Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
Embodiment 1: with reference to figure 1, Fig. 2, Fig. 5 and shown in Figure 6, a kind of have that the tip mechanism tape measure comprises chi shell 100, overcoat 5, goes up push piece 6, push piece 7, driving mechanism, dead head 8, return unit 10 and top 9 down.
With reference to shown in Figure 3, chi shell 100 is assembled by positive chi shell 1 and anti-chi shell 11, and it is ccontaining for tip mechanism that the centre has cavity, and oral area has a mouthful edge.
Overcoat 5 is located in the chi shell 100, and the center has a protruding column 5d, and this cylinder 5d center has the through hole 5f that runs through overcoat 5, has axial slide rail 5a in this through hole 5f, and there is the zigzag first helical teeth 5b this cylinder 5d bottom around forming through holes.Overcoat 5 upper ends are extended with a pair of lug 5c, and this is to being provided with a pivot pin 4 between the lug 5c, and the rearward end of overcoat 5 also has the guiding slot port 5e that passes through after 2 rotations of confession driving stem press down, referring to shown in Figure 4.
Following push piece 7 lower ends and top 9 offset, the upper end is by portion of going deep on it 73 and last push piece 6 dismountable type socket connections, lower end perisporium evagination has and is distributed with first of second ring tooth 71 and last push piece and encircles tooth 61 and present that calibration is rotary to be cooperated, it is equally distributed encircling tooth exactly, rotation is rotated according to design point of view successively, and periphery wall has second helical teeth 72 that cooperates with the first helical teeth 5b of described cylinder bottom, this second helical teeth is that radially evagination becomes second flange, slidably reciprocate with slide rail 5a in the described through hole and to cooperate, wherein under the state, second helical teeth 72 of following push piece 7 is limited among the first helical teeth 5b of described cylinder bottom, under another state, first flange 62 of second flange of following push piece 7 and last push piece 6 is involutory substantially, bounces back among the axial slide rail 5a in through hole;
Driving mechanism is used to drive push piece 6 and moves to through hole 5f upper end, driving mechanism comprises that a middle part has the driving stem 2 and the return springs 3 of bending, the first end 21 of driving stem 2 is sheathed on the pivot pin 4 and can rotates around pivot pin 4, the free end of the second end 22 for using for the application of force, this free end exposes chi shell 100, be convenient to operation, can push the upper end of push piece 6 after rotate at the middle part of driving stem 2, this return springs 3 forces the driving stem middle part to break away from the upper end of going up push piece 6.Return springs 3 is sheathed on torsion spring on the pivot pin for the middle part in the present embodiment, and torsion spring one end and overcoat 5 upper end outer walls offset, and the other end then offsets with driving stem 2.
In the present embodiment, dead head 8 and top 9 is split designs, dead head 8 is used to be provided with fixing metal top 9, be limited in overcoat 5 bottoms telescopicly, dead head 8 one bottoms are the dead head shape, the upper end is the column of being with bulge loop and has opening, toply is shaft-like and vertically is arranged in the dead head 8 and from exposing dead head 8 bottoms.
Return unit 10 forces dead head 8 to be drawn close to overcoat 5 all the time, return unit 10 is a compression spring in the present embodiment, accordingly, dead head 8 upper ends have the voltage supply bulge loop 81 that spring offsets that contracts around perisporium, the other end of compression spring then with chi shell 100 opening mouths along offseting.
Principle of work:
With reference to figure 5 and shown in Figure 6, need indentation hide top 9 when stretching out, only with hand is pressed driving stem 2, because driving stem 2 is to be arranged on the straight pin 4 and straight pin 4 is fixed on the lug 5c of overcoat 5, when driving stem 2 is pressed down by external force, driving stem 2 meeting power transmissions are in last push piece 6 upper ends, utilize first flange 62 in the slide rail 5a of through hole 5f, to slide to do rectilinear motion and go up push piece 6, when last push piece 6 slides, following push piece 7 is being pushed away by the first ring tooth 61 of last push piece 6 and is moving down, and following push piece 7 utilizes second flange to slide in the slide rail 5a of through hole 5f.Front end face circular arc concave surface headed on the bulb of top 9 elongated portion when following push piece 7 slided, force top 9 to move, because top 9 are located on the dead head 8 and fixing, top 9 are being with when moving dead head 8 to move together, the bulge loop 81 of dead head forces return unit 10 to do compression movement simultaneously, when driving stem 2 is pressed into certain stroke, second flange of following push piece 7 can break away from the slide rail 5a of overcoat 5, after second flange of following push piece 7 breaks away from the slide rail 5a of overcoat 5, cancel the external force effect this moment, driving stem 2 is resetted by resilience under the twisting resistance effect of return springs 3, and push piece 7 moves toward above-mentioned opposite direction under the energy storage effect of return unit 10 down, when second helical teeth 72 of push piece 7 contacts with the first helical teeth 5b of protruding column 5d lower surface instantly, because the first helical teeth 5b effect forces down push piece 7 to be rotated further, when push piece 7 moves to the first helical teeth 5b root instantly, second flange at the same push piece at present 7 that descends push piece 7 to stop operating can be stuck among the first helical teeth 5b, force return unit 10 stop motions, top like this 9 just stretched outside chi shell 100 easy to use.
With reference to shown in Figure 1, when need be stretching dead head 8 outside chi shell 100 and top 9 indentations when hiding, only with hand is pressed driving stem 2, when driving stem 2 is pressed onto push piece 6, the first ring tooth by last push piece 6 forces down push piece 7 to move, when following push piece 7 breaks away from the overcoats 5 slide rail 5a, the design cause because the second ring tooth of first ring tooth of last push piece 6 and following push piece staggers, under external force as the thrust of return unit 10, force down push piece 7 to take place to rotate a little, cancel pressing force this moment, driving stem 2 is rebounded under the twisting force of return springs 3 to be resetted, and following push piece 7 is subjected to the thrust of return unit 10, force down push piece 7 to moving in the other direction, when second helical teeth 71 of push piece 7 contacts once more with the first helical teeth 5b instantly, because the ramp effect of the first helical teeth 5b forces down push piece 7 to rotate once more, design arrangement is good in advance owing to slide rail 5a, near root at the first helical teeth 5b, this at present second flange of push piece 7 forward among the slide rail 5a of through hole and can bounce back, simultaneously under the effect of return unit 10, make dead head 8 power transmissions in top 9, top 9 again power transmission in following push piece 7, following push piece 7 again power transmission in last push piece 6, when the end face of dead head 8 contacts with the inwall of overcoat 5 with regard to stop motion, be hidden in fully in the housing this moment top 9, so just dwindled the volume of tape measure.
