Abstract

An HZG small-scale submachine gun is designed to counteract the impact force of a firing pin during a counter-recoil process of a bolt and a bolt spring so as to enable the gun to fire until the bolt and the bolt spring enter a bore and are in position. The gun actually belongs to a semi-free gun-lock preshoot firing pin shifting firing type with a shutting mode being a bolt feeding type. In consideration of the design, in order to shorten the length of the whole gun, a cartridge magazine is inserted into a grip and a counter-recoil spring is disposed below a front gun barrel. Bullets shot from the gun is specially designed to be single hole bokser primer submachine bullets of 8.3mm*25mm. the type of bullets is mainly characterized in that a stable hole for stabilizing the flying of bullets is arranged inside the warhead and the hole is loaded with a gun propellant powder. The bullets have two types. One type is a pointed-end warhead; the other type is an egg-shaped warhead. The oral area of the gun-barrel is processed with screw threads so that it is convenient to install a silencer. The gunstock of the gun is foldable and demountable. Allocated magazines have two types. One type is a long magazine with bullets being no less than 30; the other type is a short magazine with bullets being no less than 20. The appearance of the gun is unique; the gun looks like the big size of a pistol, is much shorter than common submachine guns, and is convenient to carry.

Description

The HZG burp gun

(1) technical field

Patent of the present invention relates to light arm manufacturing technology field, specifically reduces size to alleviating weapon weight, strengthen hazard boundary and improve precision, and raising mobility belongs to a kind of to the new art designs scheme of firearms implementation.

(2) background technology

Since history, what most of tommy guns adopted is the locking of preshoot percussion formula inertia, the benefit of this design is simple in structure, motor-driven unfailing performance height easy to process, can adapt to and under various environment, use, to be that size is less be convenient to concealed going along withly for next, and tommy gun generally in the use more adopts burst-firings, so the cartridge chamber internal temperature is very high.Because preshoot percussion formula trigger mechanism bullet before percussion is not failed into thorax, but in magazine oral area and cartridge chamber, be a tilt condition, reduced to meet accident and cocked off, but the tommy gun low precision of free gunlock preshoot percussion formula causes easily early and sends out and fried shell because of bore is overheated.Secondly less, the propellant powder quantity not sufficient of most of gubmachine gun cartridge sizes, bullet are too short, and the flight stability difference is unfavorable for precisely killing and wounding.

(3) summary of the invention

1, technical problem to be solved

This design is that gunlock and bullet are improved, and mainly is the accuracy at target that improves rifle, and requires to keep the equal advantage of original tommy gun aspect firepower and reliability, and the rifle length of will demanding perfection aspect size is shorter than conventional tommy gun.

2, technical scheme

This rifle can be divided into seven major parts substantially, and they are respectively upper casings, following casing, gunlock and front slide device, emitter, gun barrel, magazine, gun stock etc.

(1) upper casing

The upper casing front portion of this rifle is slightly higher than the rear portion, because the upper casing front portion is to be inserted in down the casing front portion, the kayser breach and the safeties of preceding sighting device, back sighting device, machine handle loose slot, machine handle assembling passage and machine handle assembling channel seal plate, upper casing standing screw hole (1) (2) (3) upper casing and following casing are arranged in upper casing.

Preceding sighting device and back sighting device

The preceding sighting device of this rifle can be divided into foresight and two side guard plates, for the ease of the aiming foresight is a right angled triangle sight plate that stands in both sides center of protecting panel, sight plate is thicker, onboard on the webbing top to the bottom go up top apart from opening a foresight aperture on the mid-point be to be inclined upwardly gradually by the webbing both sides to be point of a knife shape, it is apex of front sight, in foresight, the foresight aperture mainly is to play accurate aiming, and apex of front sight is just for slewing, back sighting device is that the backplate by a sight and both sides constitutes, a sight hole bigger slightly than preceding foresight aperture has been opened at the positive center of sight face, the center has a notch of back sight directly over the sight face, the sight hole heart and the foresight hole heart in line, and notch of back sight and apex of front sight have played accurate aiming in line like this, have played aiming fast again.

Machine handle loose slot

Machine handle loose slot is to work as rifle in emission state, gunlock and front slide guide ceaselessly front and back advance in the process again, and the front and back that the bolt handle that is connected slip guide front portion does not also stop are advanced again, but bolt handle then is to be connected to be interlinked to the outside with the slip guide to stretch out in machine handle loose slot, no matter be to pull back gunlock or in emission state with hand, therefore bolt handle all slides at this groove before and after ceaselessly that this groove must have enough length could allow the machine handle slide before and after this groove.

Machine handle assembling passage

Machine handle assembling passage is the breach below machine handle loose slot of communicating with machine handle loose slot, this breach mainly is when decomposing upper casing, then breach is by taking off upper casing thus for bolt handle, and bolt handle also will just can enter machine handle loose slot by this groove when installing casing.

Machine handle assembling channel seal plate

Upper casing is compact more must to design a plate that can seal machine handle assembling passage in order to make, the both sides of plate must be fixed on plate outside the machine handle assembling passage of casing by two screws respectively, more closely the close passage of the envelope place of this plate must evagination so in order to make passage, and the thickness of the degree of evagination and upper casing quite just snaps in passage.

The kayser breach of the tight lock of upper casing standing screw hole (1) fixing hole (2) fixing hole (3) and upper casing and following casing.

Standing screw penetrates and screws with the same screw hole of following casing from upper casing standing screw hole (1) (2) (3), thereby mainly be the fixing contour structures that forms whole rifle that makes upper casing and following casing firm, the kayser breach then is inserted in down in the kayser vertebra at casing rear portion mainly in order to prevent that upper casing and following casing from becoming flexible.

Safety lock

Safety lock is the top position of design outside the machine handle loose slot of upper casing, also pins whole carriage and gunlock and has realized preventing the rifle accidental fall and cock off thereby mainly pin bolt handle.

(2) casing under

Following casing and other tommy gun are different, and to be that one is undecomposable be made of an independent casing integral body for handle and magazine seat.

The handle inboard of following casing is that the every limit of magazine seat two broadside inwalls has been designed 4 and highly is the firmly prominent muscle of the magazine of the thick 3mm of 2.5mm, totally 8 the prominent muscle in both sides snap in respectively in the prominent muscle groove of magazine two broadsides, and the preceding bottom of following casing has diameter circular hole this circular hole consistent with the recoil rod tube to be convenient to the recoil rod tube to pass thus and just allow the upper casing front portion tightly prop up and be convenient to firm recoil rod tube.

(3) gunlock and front slide device

Gunlock front slide device, advancing guide again is a fixing integral body, wherein is furnished with the tight tube of gun barrel in the front slide device, sliding sleeve is advanced again in front and back in the process keeps balance to help improving precision with gun barrel, advancing guide again mainly holds the recoil rod tube and passes in the guide thus, and the kicker front end withstands guide, the rear end props up the recoil rod cylinder base, under the effect of kicker power, push sliding sleeve and gunlock to the place ahead position location thus, gunlock shows complicated slightly on the whole, and inner its mainly divides movement and two most of formations of firing pin assembly.

Movement is a long boss cylinder unit, and its hollow can be held firing pin and seesaw, and the extractor of its top is fixed together with movement and springs into thorax and enter in thorax with movement in the multiple moment of entering the location along with gunlock send

About, the firing pin assembly has 2 boss, firing pin is the small boss center that is fixed on the firing pin assembly, little boss is consistent with movement rear boss diameter, gunlock retreat and the percussion process in, small boss bears firing pin and prevents that in knockout process firing pin is out of shape the rear boss that props up movement, make its dispensing impact too, a big boss surface of firing pin module back has the dark screw thread of 2mm, this screw thread be convenient in the internal thread that the firing pin assembly screws in the gunlock afterbody with the firing pin assembly and before movement be fixed in the gunlock, there is the hole of 4 symmetries big boss back, be convenient to snap in the hole its rotation is decomposed with spanner, movement spring one end snaps in firing pin assembly small boss, the rear boss that the other end snaps in movement makes movement rear boss and firing pin assembly small boss have only the 2.5mm distance, when pushing away on the gunlock plays fin bullet pushed cartridge chamber behind the location, because the spring power of kicker is far longer than the spring power of movement spring, along with gunlock and firing pin assembly compression movement spring, movement was located the firing pin that remains static and was then moved on gunlock and hit the combustion bullet about 2mm this moment.But movement projection 2mm forward before movement location because under the effect of movement spring, just expose needle point when striker head also has 1mm in the movement hole this moment, thereby can not cause that early discovery resembles.

The gunlock outside, it is vertical plane that the top is the circular arc dual-side, the base, by both sides, dual-side place the wide even surface of 2mm is arranged respectively, this face mainly leans against down on casing end face two webbings, inboard have the dark boss side surfaces of 2mm to lean on into the side on both sides, casing top down mainly sliding for the ease of front and back equally, its gunlock and front slide guide top sidepiece advance in the process with the consistent carriage that tightly covers back gunlock and whole inside at upper casing of upper casing top side portion cavity shape in front and back again, whole limit face is all closely fitted with following casing, can not produce distort or about teetertotter and not only improved mobility but also guaranteed precision.

One section dead slot of gunlock movement bottom, this groove mainly hold bullet makes bullet play fin and this groove of movement position and on-hook bayonet socket place joint except that pushing away bullet fin groove in addition in addition near pushing away.

Recoil rod tube fixation kit is to be welded on down the preceding lower position of casing bore, wherein the fixation kit front portion is one and is threaded post, and recoil rod tube rear inside wall has the silk mouth, the guide rod tube tightly can be rotated with and fix on the threaded post, guide rod tube front portion then is one and has 4 driving holes and be convenient to the dismounting of guide rod tube.

(4) emitter

The emission of this rifle and simply be divided into and be trigger, trigger bar, and three major parts of sear.

Trigger:

In trigger webbing top and the limit that the connecting rod of trigger is connected a rectangle groove is arranged, respectively there is a rectangular groove on the sidepiece both sides, that groove that is connected with trigger bar is to allow the front of trigger bar snap in this groove can transfer up and down, thereby each groove of sidepiece both sides is to have formed single running fire conversion in order to allow the connecting rod of trigger be used to wear both sides and can transfer up and down, is running fire when being single-shot tuning below during the tuning top.

Trigger bar:

The connecting rod that links to each other with trigger is arranged before the trigger bar, the connecting rod middle part is both sides and is extended by handle inwall sidepiece, the connecting rod rear portion links to each other with sear, magazine is stretched out by the empty position in the connecting rod when handle inserts and pushes away the bullet fin on a little higher than gunlock of first bullet in the magazine, the single-shot bar is connected in the later half position on connecting rod both sides, rise to the single-shot startup groove face handing-over of gunlock and gunlock respectively by casing both sides in rear in the handle, the connecting rod rear portion is provided with a sear and frees tenon, tenon connects in the tenon groove at connecting rod rear portion (being the tenon seat) by tenon pin and tenon spring, tenon can be depressed along with rising to the location under the effect of tenon spring power again, there is a plate machine connecting rod circlip circle at tenon seat rear portion, extension of connecting rod spring this ring, and the other end hangs down in the spring hook of casing back.

Sear:

Sear is installed on down in the raceway groove in the tight seat board of casing, sear top gunlock free sear face (startup inclined-plane) be gunlock when retreating thus the inclined-plane slide and depress sear, make sear lift the location on again, sear on-hook face snaps in the gunlock bayonet socket, gunlock is hung on the rear, the sear both sides respectively have one zanjon to hold the sear spring on sear both sides, and the sear spring on sear and both sides is lived by sear together and sold fixing.

The trigger mechanism principle

When the top position that the connecting rod handle on the trigger bar is pushed the trigger connecting hole to be that the single-shot position is lifted on the trigger bar this moment and the single-shot bar that is connected both sides, trigger bar postmedian position also with on lift to the inboard boss face of gunlock with following casing, the anterior both sides of boss face respectively have one to press down the inclined-plane, and at the single-shot lever pin at single-shot bar rear portion as fulcrum.This moment, connecting rod rear portion sear was freed the card vertebra slightly to moving down, and move to the front upper place when cocking plate machine drives trigger bar, and the single-shot lever pin was as fulcrum.Sear draws to the front lower place and forces sear descend to discharge gunlock along with freeing the card vertebra, when gunlock in the reach process, press down the inclined-plane on each one on both sides, boss bottom and depress the single-shot bar to front slide, the whole rear portion of single-shot bar drivening rod descends and the card vertebra that combines with sear also descends thereupon, before entering the position again, discharge sear and return original position, in fallback procedures, allow sear in position that it is hung into the rear again when gunlock enters position percussion bullet again, unclamp trigger this moment.Along with trigger under the effect of trigger bar spring moves backward to front rod, this moment the single-shot bar to the rear lower displacement moving and with the single-shot lever pin as fulcrum, card vertebra position on the connecting rod is then along with under the effect that pushes away spring on the trigger bar, move to the back upper place, free card vertebra and sear free the reverse side phase resistance of face force the card vertebra to descend and free when retreating into card vertebra along with the effect of card vertebra spring time and on lift and be interlocked with the sear face of freeing again, cocking again, connecting rod drives sear, discharges gunlock formation semi automatic fire thereby descend thereupon.The lower position of pushing the trigger connecting hole when the connecting rod handle to is that running fire position trigger bar this moment descends and the also decline thereupon of single-shot bar, break away from boss and be that the connecting rod at fulcrum rear portion is along with moving in the effect that pushes away spring on the trigger bar down with the single-shot lever pin, block that vertebra is freed face and the sear face of freeing is interlocked this moment, the surplus buckling surface of foot is arranged, pull plate machine connecting rod and drive sear decline release gunlock, this moment, gunlock advanced in the process because the single-shot bar descends to leave the boss inclined-plane again, pressed down inefficacy so press down the generation of being separated by of boss inclined-plane and single-shot bar.Work as gunlock this moment and enter the position again, only otherwise unclamp trigger, behind the connecting rod free that the card vertebra still fastens sear and sear still is in the decline state, gunlock retreats along with the effect of powder gas when falling back on the sear position, sear is to be in the decline state, thereby hang less than gunlock, thereby when extractor with push away and play fin shell case gunlock from shell throwing-out window is dished out after is still answered into formation full automatic fire automatically so be separated by with gunlock on-hook bayonet socket.

Ejector activity principle

The ejector of this rifle is different with the design of traditional type, it mainly is in gunlock is answered into motion process repeatedly, ejector then snaps in and pushes away the ejector groove that plays the fin centre position, along with the startup inclined-plane at ejector groove rear portion under the effect of ejector spring and motion one on the other, when gunlock retreats the bullet that puts in place to the ejector position, ejector has left the startup inclined-plane and has lifted and carry out ejection upward, when gunlock enters the position again because there is an inclined-plane at the rear portion of ejector groove, this moment, incline position was just below above the ejector pressing to ejector.

(5) gun barrel

The gun barrel precision of this rifle directly has influence on the dispersion radii of bullet need process interior thorax chromium plating to guarantee the life-span through forging.Gun barrel is to be fixed on down in the gun barrel holder of casing, and an end is that fixedly resistance face heads into an end of holder, the other end then be by gun barrel fixedly bung flange fix; When bung flange tightly revolves, forward tensile force is played at the breech position of whole gun barrel; And other end gun barrel breech fixedly resistance face and holder are also just fixed tightly more, shell hook groove is taken out at the bore position, push away bullet fin groove, mainly just seal close this groove to guarantee precision so also should to about reach 1.45mm, push away the bullet fin at this moment when its firing pin percussion primer behind the gunlock location.And button shell hook still remains static when firing pin is pulled the trigger at the close button shell hook groove of envelope behind the location with movement, the gun barrel inwall has 6 right hand twists, land is triangular pyramidal, it mainly is the tapered resistance that can reduce bullet of land that groove is hypotenuse shape, land is 0.15mm more deeply, and the muzzle place has screw thread to be convenient to install muffler.

(6) magazine

The magazine that this rifle was equipped with can be divided into military or alert usefulness, and the longer cartridge capacity of military version magazine is not less than 32, is fit to charge.Alert short in convenient going along with the type magazine, but cartridge capacity is many like that not as good as military version, and mainly preferably generally be not less than 20 bullets with semi-automatic emission.Two kinds of magazines adopt double unidirectional ammo feed mechanism, promptly the position from magazine resistance bullet face is that benchmark is an inclined plane with its two webbing downwards, all bullets below the inclined plane are double, thereby upwards form single owing to the inclined-plane upwards makes the appearance bullet space of upper part magazine narrow down gradually to hindering the bullet face from the inclined plane.In magazine, fill bullet, insert handle and gunlock pulls to the rear and allows sear tangle the formation arm-to-arm, the interior first bullet of magazine this moment stops with resistance bullet face, bullet is then slightly upwards near the bore mouth, below the center of thorax mouth, this moment, bullet was an inclination, but the first bullet of magazine all is to be single in magazine, so promptly be not partial to the right-hand left of yet not being partial to of thorax mouth, so not only guaranteed that bullet into is smooth and easy but also guaranteed the precision of rifle, when advancing to push away to play fin again, gunlock pushes away when springing into thorax, when promptly pushing away bullet and in bore, advancing 15mm, then resistance bullet face is just crossed at the later half position of bullet, lost efficacy thereby form resistance bullet face, and inferior bullet rises to resistance with follower and play the kept man of a noblewoman and send out bullet and form and be forced to upwards and the extractor at movement top just hooks root edge limit groove under the effect of magazine spring power, bullet entered bore 1/3 and became same balance axis with bore this moment, thereby improved precision, magazine two broadsides have equally distributed 4 rib grooves, blocked by 4 ribs in the handle magazine is played firm effect.The tenon of this bullet casket equally is arranged on the handbar at trigger guard rear with conventional semi-automatic handgun, but because the tommy gun magazine is long and cartridge capacity is more than the capacity of magazine of pistol, therefore the tenon face of magazine catch should be than the tenon face length of the magazine catch of pistol, and below, magazine inclined plane then is provided with a magazine catch groove.

(7) gun stock

This rifle gun stock is that collapsible mainly to be convenient to shooter's secret going along with, and gun stock is not only collapsible but also can take off arbitrarily, and gun stock mainly is divided into the gun stock seat, and gun stock bar, shoulder frame plate and lock pin constitute.Pintle hook lock seat after the tail end of gun stock seat has designed one, have in the back pintle hook lock seat one with the square hole that communicates up and down (pintle hook lock seat hole) thus mainly be to be convenient to lock pin the gun stock of open mode to be locked in whole gun stock is fixed in this pintle hook lock seat, equally upper casing right front have a pair of before the pintle hook lock seat, preceding pintle hook lock seat mainly is in order to be fixed on gun stock on the body of a gun tightly after gun stock is folding, lock pin is a square strip device, when lock pin inserts from pintle hook lock seat hole when not locating fully, lock pin stator under the lock pin is in the withdrawal lock pin bar, when stretching out promptly in by the lock pin bar, lock pin location back lock pin stator locatees, after gun stock is folding, the trigger guard front portion have one section surplus with the distance mainly for when shooter has little time to open gun stock running into emergent target, can be convenient to left-handed herein.The right hand can be held the handle cocking and shoot immediately.Gun stock is opened or be folding all is right-hand at rifle.When opening since gun stock right-hand when aiming cheekbone near gun stock, and this moment, right eye was just aimed at sight and foresight is convenient to slewing.

Bullet:

The bullet that this rifle is allotted is custom-designed 8.3*25mm single hole Bock plug fire in a stove before fuel is added formula gubmachine gun cartridge.It is big that this plays size lengthening appearance dose, the difference that belongs to big power gubmachine gun cartridge and calipers bullet mainly is because there is a diameter positive center, bullet bottom is the stable hole of 10mm for the 4mm degree of depth, propellant powder also is housed in the stable hole, the total length of bullet is 20mm, and is longer than the gubmachine gun cartridge bullet of the 9mm pistol cartridge of conventional formula and 7.62mm.When bullet flies away from muzzle since stable hole in propellant powder not only can keep the flight stability of bullet but also can strengthen the motive force of powder gas bullet, thereby strengthened lethality, improved precision again.This bullet has pointed bullet and avette bullet to be the plain edition bullet.Pointed bullet mainly is can effectively destroy flak jackets.Avette bullet requires to fail stronger, and it is fast to discharge kinetic energy.

Cutfit is decomposed in the scouring of rifle

The scrubbing tool of this rifle be equipped with specially one piece long be the hairbrush of 270mm, multifunctional screw driver and a special spanner that decomposes striker post.

Hairbrush mainly is to be used to clean gun barrel, multifunctional screw driver is mainly used in the screw rod that decomposes in upper casing and the screw rod fixing hole (1) (2) (3) that following casing is connected etc., and the special spanner of decomposition striker post can decompose gun barrel fixedly bung flange, recoil rod tube and striker post etc.

3, beneficial effect

The design concept of this invention must be shorter than conventional tommy gun with the size design of tommy gun, quality is lighter, the semi-free gunlock preshoot percussion movement that adopts advances the thorax enclosed type, secondly bullet has also been carried out improve having improved precision, in the practical value that closely has the anti-terrorism equipment.

(5) specific embodiment

This design is fairly simple, magazine inserts just as the neat tommy gun of the crow of Israel in by handle on the structure of profile, but counterrecoil mechanism and gunlock all adopt the semi-automatic handgun sleeve of traditional type and the gunlock principle in the sleeve, trigger method still impacted in the past to be sent out rather than the hammer percussion, length when the length pin pulled to the rear greater than automatic pistol with front sleeve when therefore full rifle did not carry a gun holder, shorter than the neat tommy gun length of original crow, but adopt semi-free gunlock preshoot percussion movement to advance the thorax enclosed type, thereby make precision be better than the neat tommy gun of crow of Israel, and firepower and effective area and crow are quite neat, the design concept that the firing lock of this design is stepped on tommy gun in the department that all adopts Britain aspect the sear principle, trigger bar and single-shot bar adopt Switzerland West Germany your the pistol principle that continues, because of your the pistol single-shot bar that continues has only one to depress when sleeve backwards, this single-shot bar is in order to make both sides dynamics balance, so each single-shot bar of plate machine connecting rod bifurcated the right and left is depressed when the gunlock preshoot, safety lock has then adopted spinach spinach Sha 41 formula tommy guns insurance principle of the former Soviet Union, just spinach spinach Sha tommy gun safety lock is that design is on the machine handle, and this safety lock is that design is on casing, gunlock then adopts semi-free gunlock, just as the HKmp of Germany ₅Tommy gun is the same, but mp ₅Tommy gun head more complicated adopts the roller enclosed type; When this design then adopts movement to advance the thorax locking, thereby gunlock is simplified, and the design of bullet head is to adopt the telescopic howitzer principle of Belgian FNC37mm rifle, because rifle grenade is purely by fin stabilization; And it is stable unlike the bullet bullet by bore and rifling, therefore bullet is passed the motive force that makes the center and adds stabilizer much larger than the motive force of the powder gas at edge and be as the criterion with the positive center of howitzer and a little form lonely line and accurately kill and wound by the positive center of howitzer when launching, therefore this bullet adopts this principle that the bullet center is added with a deep hole, in this deep hole, also load propellant powder, make the motive force at bullet center add the stable of bore and rifling, make it improve killing and wounding of precision the bullet lengthening again greater than the motive force at bullet edge.To guarantee convenient aiming, the specific embodiment of total this rifle of coming back is to adopt the advantages of multiple rifle design to form at body of a gun right-hand member for gun stock design, adds some uniqueness of oneself and improves design and design.

Claims

1. this rifle is the most outstanding is improvement aspect gunlock and counterrecoil mechanism, and gunlock becomes balance to seesaw with gun barrel with counterrecoil mechanism when advancing again, adds because semi-free gunlock preshoot percussion movement advances the thorax enclosed type to guarantee closed and precision.

2. for the dispersion radii that reduces bullet improves accurate hit rate, be added with the stable hole of a stable bullet flight at the bullet center, again bullet extended.

3. the tommy gun of the unique outlook of this design and traditional type is different, magazine is by inserting in the handle, the kicker design is below preceding gun barrel, have a few picture in the contour structures of rifle if take off gun stock, therefore size is littler than the size of conventional tommy gun, and the compacter user of guaranteeing of inner body is convenient to secret going along with.
