Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, well-known features have not been described in detail in order to avoid obscuring the embodiments of the invention.

In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the present invention. It will be apparent that embodiments of the invention may be practiced without limitation to the specific details that are set forth by those skilled in the art.

First embodiment

Referring to fig. 1 to 10B, a tray box according to a first embodiment of the present invention and a combined tray box 100 formed by connecting tray boxes will be described.

The pallet bin referred to herein is a container, preferably a collapsible container.

The case 1 of the tray case includes a chassis 50, side plates 51 (i.e., first plates) disposed at both ends of the case in a lateral direction (i.e., first horizontal direction), and end plates 52 (i.e., second plates) disposed at both ends of the case in a longitudinal direction (i.e., second horizontal direction). Wherein at least one of the side panels 51 is removable from the case and the end panel 52 is foldably connected to the chassis 50. It should be noted that "transverse" as used herein refers to the width direction of the case, and "longitudinal" refers to the length direction of the case.

Two cases 1 from which one side plate 51 is removed are connected side by side in the lateral direction of the case 1 to form a combined tray case 100. It will be appreciated that the size of the combination pallet magazine 100 is approximately twice the size of the magazine body 1 of the pallet magazine.

Preferably, as shown in fig. 3B, chassis upright posts extending upwards are arranged at the upper parts of four corners of the chassis of the tray box, and chassis feet are arranged at the lower parts of four corners of the chassis. Screw holes 13 are formed in the end face (namely the second face) of the chassis upright post, guide grooves 12 are formed in the side face (namely the first face) of the chassis upright post, and circular matching holes 11 are formed in the side face (namely the first face) of the chassis foot. Also preferably, the upper corner of the end plate 52 is provided with a connection lock 20 for connection.

The "first surface" of a member in the present invention refers to a surface of the member facing the outside or the inside of the case in the first horizontal direction, and the "second surface" of a member refers to a surface of the member facing the outside or the inside of the case in the second horizontal direction.

Correspondingly, the first connecting mechanism 2 (refer to fig. 4A, 4B) is installed at the upper end face of the chassis upright adjacent to the two cases 1 for cooperation with the screw holes 13. The first connection mechanism preferably includes a first connection plate 201 and a first screw 202 extending inward from the first connection plate 201 in the longitudinal direction of the case 1. When the first connecting mechanism 2 connects the two boxes 1, the threaded holes 13 are matched with the first screws 202, and the two chassis uprights are connected together through the first connecting plate 201.

More preferably, in order to prevent the screw from being lost after the connection plate is detached, the first connection mechanism 2 may be provided as a screw escape prevention structure, taking the first connection mechanism 2 as an example. As shown in fig. 4B, the first connection plate 201 is provided with a threaded hole M1, the screw head root of the first screw 202 is provided with a unthreaded polished rod, the diameter Φ1 of the polished rod is smaller than the diameter Φ2 of the threads of the first screw 202, and the length L1 of the polished rod portion is greater than the length L2 of the threaded hole of the first connection plate 201. When the first screw 202 is screwed from the screw hole of the first connection plate 201 and the screw hole of the first connection plate 201 is located at the polish rod portion of the first screw 202, the first screw 202 is engaged with the first connection plate 201 to realize the anti-drop function. It will be appreciated that at this point the screw is disconnected from the connection plate and the screw is manually re-threaded into the threaded hole of the connection plate to disengage the screw from the connection plate. When the combined pallet box 100 is assembled or disassembled, the threaded holes of the first connecting plate 201 are always positioned at the polished rod part of the first screw 202 in the process of connecting or disassembling the first connecting mechanism 2, so that screw drop prevention (namely, screw drop prevention and connecting plate loss) is realized.

Preferably, in order to increase the connection strength of the first connection plate 201, male hooks (as shown in fig. 4B) may be provided at both sides of the first connection plate 201, and the chassis upright is provided with grooves corresponding to the male hooks. After the first screw 202 is connected and fastened with the chassis upright, the convex hook is embedded with the groove, so that the tensile and compressive capacities of the first connecting plate 201 are increased, and meanwhile, the first screw 202 is prevented from being damaged excessively by shearing force.

Correspondingly, the second connecting means 3 (see fig. 5) are provided on the side of the chassis foot adjacent to the two housings 1 for cooperation with the cooperation holes 11. The second connection mechanism 3 preferably includes a lock bolt 301, an adjustment bolt 302, an adjustment nut 303, and a lock nut 304. When the second connecting mechanism 3 connects the two boxes 1, the locking bolt 301 passes through the matching hole 11 on the chassis, the adjusting bolt 302 and the adjusting nut 303, and the two chassis are connected through the locking nut 304. After the installation is completed, the adjusting bolts 302 and the adjusting nuts 303 are positioned between the adjacent chassis feet of the two boxes 1, and the adjusting bolts 302 and the adjusting nuts 303 respectively prop against the adjacent chassis feet of the two boxes 1 through adjustment.

More preferably, the adjustment bolt 302 is provided with a through hole extending along its axis and having a smooth inner surface, and the body portion of the lock bolt 301 is fitted into the through hole so that the adjustment bolt 302 can slide in its axial direction with respect to the lock bolt 301. In the present embodiment, the adjusting bolt 302 and the adjusting nut 303 are formed together as an adjusting assembly, and it is understood that the adjusting bolt 302 and the adjusting nut 303 cooperate to form, in effect, together as a washer of adjustable thickness positioned between the two housings 1.

The arrangement is such that when two pallet boxes are to be joined together by fork-lift truck or the like, especially when the pallet boxes are to be fork-lifted in a folded and stacked condition, adjacent chassis feet of the two boxes 1 do not come together relatively so as to cause the pallet boxes to arch and deform. The second connecting mechanism 3 is provided with an adjustable structure instead of a fixed size, because the chassis upright post and the chassis foot of the embodiment of the invention are two parts, positioning errors exist in production, and when the first connecting mechanism 2 is connected, the distance between the adjacent chassis feet of the two boxes 1 is not necessarily the same, so that the adjustable structure can ensure that the adjusting bolt 302 and the adjusting nut 303 respectively prop against the adjacent chassis feet of the two boxes 1.

It will be appreciated that if the chassis upright extends downwardly and the mating aperture 11 is provided in the chassis upright, both the first and second connection means 2, 3 are connected to the chassis upright, a fixed structure may be provided instead of the adjustable second connection means 3. In this embodiment, the first connecting mechanism 2 has a small height due to the limitation of the structure, and the upper parts of the chassis uprights can be connected only by two first screws 202, so that the second connecting mechanism 3 is required to be connected to the lower parts of the chassis four corners. In other embodiments, not shown, the second connecting means 3 can be omitted if the connection strength is sufficient, if the first connecting means 2 is allowed to extend downwards, and the upper and lower parts of the chassis upright can be connected by 4 first screws 202.

Preferably, a connecting upright 4 extending in the vertical direction is connected between the adjacent end plates 52 of two cases 1. The two sides of the lower end of the connecting upright 4 are provided with pin shafts 401 (refer to fig. 6B), and the pin shafts 401 and the lower part of the connecting upright 4 are preferably integrally formed through casting and other processes. The pin 401 can be matched with the guide groove 12 on the chassis to realize the up-and-down sliding and rotation of the pin 401 in the guide groove 12, so that the connecting upright post 4 can be folded.

More preferably, the upper end of the connecting upright post 4 is provided with a locking hole 402 (as shown in fig. 7A), the locking hole 402 cooperates with the connecting lock 20 on the end plate 52 to realize connection of the end plates 52 of the two boxes 1, and the top end of the connecting upright post 4 can be provided with a stacking block 403 for stacking two boxes on the combined box 100 (i.e. smaller boxes on the combined box 100). When stacking two large boxes in an assembled state, the middle part can be stacked to bear stacking force besides four corner stacking, so that the bearing capacity of the combined tray box 100 is improved.

Preferably, the modular tray case 100 further comprises a closing plate 5 (fig. 8A to 8B) located between the chassis 50 of the two cases 1 and extending in the longitudinal direction. The sealing plate 5 spans the side beams of the two chassis to shield the assembly gap of the two boxes (the gap between the side beams of the adjacent chassis of the two boxes 1). The side beams of the chassis have grooves which are wider at the bottom and narrower at the top, and the cross section of the sealing plate 5 (fig. 8B) corresponds to the grooves of the side beams. The side of shrouding 5 cooperates with the side of the side beam of chassis, and behind two box 1 connection, because the reason that down is wide and narrow on, shrouding 5 can not be dismantled to also can play firm connection.

It will be appreciated that the closure plate 5, the connecting stud 4, the first connecting means 2 and the second connecting means 3 all constitute connecting members for connecting the two housings 1. The combined pallet box combined by the connecting members can also be folded in the same manner as the pallet box, and the locks 6,7 are opened first, two sets of two end plates 52 connected together are folded, and then the two side plates 51 are folded, as shown in fig. 2A.

The combination pallet magazine 100 may also comprise a tie rod 8 connected between the top ends of the two connecting uprights 4. Referring to fig. 9A and 9B, the pull rod 8 preferably includes a latch 801, a catch 802, an operating handle 803, and a pull rod body 804. The latch 801 and the operating handle 803 are fixedly connected and can slide along the length direction of the pull rod body 804 (i.e., the longitudinal direction of the case 1). The upper part of the connecting upright post 4 is provided with a through hole. The width B of the pull rod body 804 is matched with the dimension B1 of the stacking block 403 at the upper end of the connecting upright post 4 during assembly, the width C of the clamping groove 802 is matched with the dimension C1 of the stacking block 403, and the dimension D of the bolt 801 is matched with the dimension D1 of the stacking block 403, so that the bolt 801 penetrates through the through hole of the connecting upright post 4, and the pull rod 8 is completely locked with the connecting upright post 4 (refer to fig. 10B).

More preferably, a spring may be provided to maintain the locked state. In the locked state, the spring is natural or has a slight biasing force, and when the operating handle 803 has a certain displacement with respect to the locked state, the spring has a biasing force that biases the pull rod 8 toward a state in which the pull rod 8 and the connecting column 4 are locked with each other. The tie rod 8 can play a role in connection reinforcement when the load is swelled. When folded, the pull rod 8 can be folded together with the box and placed on the folded connecting upright posts 4 between the adjacent chassis upright posts.

Two box bodies 1 with one side plate 51 detached are firstly closed, the sealing plate 5 is buckled in a groove of a side beam of the chassis, the pin shafts 401 connected with the upright posts 4 are aligned with the guide grooves 12, the two box bodies 1 are abutted to enable the side beam of the chassis to be jointed with the sealing plate 5, and meanwhile, the pin shafts 401 enter the guide grooves 12. Subsequently, the first screw 202 of the first connection mechanism 2 is cyclically screwed down, while the male hook on the connection plate 201 is engaged with the groove on the chassis upright, the adjusting bolt 302 and the adjusting nut 303 are screwed down to a smaller length and put between the two chassis, the locking bolt 301 is penetrated, the adjusting bolt 302 and the adjusting nut 303 are adjusted to be respectively contacted with the chassis of the two cases 1, the locking nut 304 is screwed down, and the lock 20 is locked, thereby completing the assembly of the combined tray case 100. The disassembly process of the combination pallet magazine 100 is opposite to the above process, and will not be described again.

Second embodiment

Fig. 11 to 14B show a tray box according to a second embodiment of the present invention and a combined tray box 200 formed by connecting tray boxes. For the sake of simplicity, the description of the present embodiment that is the same as or similar to the first embodiment will be omitted.

In the present embodiment, the end plate (i.e., the first plate) of the case body 31 of the tray case is detachable, and the side plate (i.e., the second plate) is foldable. It will be appreciated that in this embodiment, the first horizontal direction is the longitudinal direction of the case 31, and the second horizontal direction is the transverse direction of the case 31.

Two cases 31 (see fig. 11) with one of the end plates removed are connected side by side in the longitudinal direction of the case 31. The side of the chassis upright (i.e. the second face of the chassis upright) is provided with a second threaded hole 41 (i.e. one embodiment of a threaded hole) for connecting to the box, and the second face of the upper corner of the side plate is provided with a third threaded hole 42 for connecting.

Correspondingly, the third connecting mechanism 32 (i.e. another embodiment of the first connecting mechanism) is disposed on the side surface of the chassis upright post and the chassis foot adjacent to the two boxes 31, and specifically consists of a second connecting plate 43 and a second screw 44, when the two boxes 31 are connected, the second screw 44 is matched with the second threaded hole 41, and the chassis of the two boxes 31 are connected together through the second connecting plate 43.

Correspondingly, the fourth connecting mechanism 33 (i.e. another embodiment of the first connecting mechanism) is disposed on the outer surface of the upper corner of the adjacent side plates of the two boxes 31, and specifically consists of a third connecting plate 45 and a third screw 46, and when the two boxes 31 are connected, the third screw 46 cooperates with the third threaded hole 42 to connect the adjacent side plates of the two boxes 31 together. The folding mode of the box body after connection is the same as that of the original box body, firstly, the end plate upper locks 34 and 35 are opened, the two end plates are folded, and then the two groups of two side plates connected together are folded in sequence.

In order to increase the connection strength of the second connection plate 43 and the third connection plate 45, a convex hook similar to the first connection plate 201 in structure can be arranged on the second connection plate 43 and the third connection plate 45, and grooves corresponding to the convex hook are arranged on the chassis upright post and the upper corner (side plate stacking piece) of the side plate. The connection form and function of the male hooks and the female grooves are similar to those of the first connection plate 201, wherein the female grooves corresponding to the male hooks of the second connection plate 43 can use the guide grooves 12. In addition, a stud may be disposed in the middle of the second connecting plate 43 and the third connecting plate 45, where the stud extends in the vertical direction and is used to connect the two boxes 31 and space the two boxes 31 apart from each other, so as to avoid difficulty in connecting the two boxes 31 by the second connecting plate 43 and the third connecting plate 45 due to machining and welding errors of the chassis end edge beam, the chassis upright, the chassis foot and the side plate side upright (for example, the two boxes 31 cannot abut against each other and the screw cannot be centered with the screw hole due to machining and welding errors). Another function of the studs is to prevent the two boxes 31 from being forced closer together when the joined large boxes are lifted, causing the boxes to deform.

Preferably, screw anti-drop devices similar to the first connecting mechanism 2 can also be arranged on the third connecting mechanism 32 and the fourth connecting mechanism 33.
