Description

Technical Field

[0001] The invention relates to a logistics box, in particular to an interlocking mechanism of a turnover box. Background Art

[0002] Turnover boxes, also known as logistics boxes, are widely used in machinery, automobiles, home appliances, light industry, electronics and other industries. They are suitable for transportation, distribution, storage, circulation and processing in factory logistics. Turnover boxes can be used in conjunction with a variety of logistics containers and workstation equipment, and are used in various warehouses, production sites and other occasions. They are essential items for production and distribution companies to carry out modern logistics management.

[0003] During the logistics transportation process, some valuables need to be placed in turnover boxes. To prevent loss, the turnover boxes need to be locked. Usually, if the turnover boxes need to be locked, each box needs a lock, and they need to be opened one by one. In addition, there is no connection between the upper and lower layers of the turnover boxes. When several layers of boxes are moved together, the bottom box must be lifted up to move them together, which has great limitations. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an interlocking mechanism for a turnover box, which effectively overcomes the defects of the prior art.

[0005] The technical solution of the present invention to solve the above technical problems is as follows:

[0006] A kind of interlocking mechanism of turnover boxes, used for locking multiple turnover boxes stacked up and down, the interlocking mechanism comprises a lock body and a position holding mechanism, the lock body can be slidably assembled at the two ends of each of the above-mentioned turnover boxes, and the positions of the lock bodies at the two ends of the multiple turnover boxes correspond to each other up and down, the lower parts of the two sides of each of the above-mentioned lock bodies are respectively provided with card grooves running through the two ends, and the lower ends of the above-mentioned lock bodies on all turnover boxes except the bottom layer are respectively hinged with hook assemblies on both sides, and under the action of external force, the above-mentioned lock bodies at the two ends of each layer of the above-mentioned turnover boxes are pushed upward to move upward, and at the same time, the above-mentioned lock body drives the hook assemblies on both sides to move closer to the inner side below it and hook the card grooves on both sides of the above-mentioned lock body corresponding to the lower layer, so that the multiple lock bodies in the upper and lower directions are connected to each other, and the above-mentioned position holding mechanism is used to connect with the lock bodies after the two ends of the above-mentioned turnover boxes on the top layer move upward, and keep them in the current position.

[0007] The beneficial effects of the present invention are: reasonable structural design, simple and convenient operation, and easy transportation.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, a seat body is installed at both ends of each layer of the turnover box, and a slideway that passes through the upper and lower parts is provided at one end of the seat body away from the turnover box. The lock body is slidably installed in the corresponding slideway, and the end of the seat body away from the turnover box leaks out of the slideway.

[0010] The beneficial effect of adopting the above further solution is that the design of the seat body facilitates good and stable assembly of the lock body on the turnover box.

[0011] Furthermore, the hook assembly includes a connecting rod and a vertically arranged hook-shaped hook, one end of the connecting rod is hinged to the corresponding side of the lower end of the corresponding lock body, one end of the hook is hinged to the side of the corresponding seat body away from the turnover box, and the end portion is hinged to the other end of the connecting rod, and the other end of the hook is provided with a hook portion, and the hook portions of the hooks on both sides of the same lock body are close to each other. The lock body moves upward under the action of external force, and drives the connecting rods and hooks on both sides to work together, so that the hooks on both sides are flipped downward and close to each other, and hook the corresponding slots of the lock body in the lower layer.

[0012] The beneficial effect of adopting the above further solution is that the hook assembly is simple in design, can stably engage and lock with the lock body adjacent to the lower layer, and is relatively simple and convenient to operate.

[0013] Furthermore, the upper part of the turnover box at the uppermost layer is covered with a box cover, and the position holding mechanism is fixed to the upper part of the box cover.

[0014] The beneficial effect of adopting the above further solution is that it facilitates the safe storage of the topmost items. At the same time, the position holding mechanism is designed on the box cover to facilitate the disassembly and assembly of the box cover without affecting the normal use of the turnover box.

[0015] Furthermore, the upper and lower ends of the two adjacent lock bodies are in contact with each other, and when the lock bodies move upward, the upper ends of the lock bodies extend out of the upper ends of the turnover boxes of the corresponding layer.

[0016] The beneficial effect of adopting the above further solution is that the upper and lower adjacent lock bodies fit tightly together and the connection between the structures is relatively stable.

[0017] Furthermore, the position holding mechanism is a linkage lock, and lock seats are fixed at the two ends of the upper part of the uppermost turnover box corresponding to the positions of the lock body, and the two lock core rods of the linkage lock pass through the two lock seats respectively. Under the action of external force, the linkage lock can drive the ends of the two lock core rods to synchronously extend out of the two lock seats, or retract into the corresponding lock seats. The upper ends of the lock bodies at both ends of the uppermost turnover box are penetrated by lock holes matching the lock core rod. When the lock body of the uppermost layer moves upward to the position where the lock hole corresponds to the lock core rod, the linkage lock can drive the two lock core rods to pass through the two lock seats respectively and extend into the corresponding lock holes.

[0018] The beneficial effect of adopting the above further scheme is that the position holding mechanism is relatively easy to use and can quickly complete the locking cooperation with the upper lock body, so that the multi-layer turnover box is firmly connected and easy to carry subsequently.

[0019] Furthermore, a handle is installed on the upper part of the box cover.

[0020] The beneficial effect of adopting the above further solution is that it is convenient to lift the multi-layer turnover boxes for transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0032] Example: Figures 1 to 3 As shown, the present embodiment provides an interlocking mechanism for a turnover box, which is used to lock a plurality of turnover boxes 3 stacked up and down. The interlocking mechanism comprises a lock body 1 and a position holding mechanism 2. The lock body 1 can be slidably assembled at the two ends of each of the turnover boxes 3, and the positions of the lock bodies 1 at the two ends of the plurality of turnover boxes 3 correspond to each other up and down. The lower parts of the two sides of each of the lock bodies 1 are respectively provided with card grooves 11 passing through the two ends. The lower ends of the lock bodies 1 on all turnover boxes 3 except the bottom layer are respectively hinged with hook components 12. Under the action of external force, the lock bodies 1 at the two ends of each layer of the turnover boxes 3 are pushed upward to move upward. At the same time, the lock body 1 drives the hook components 12 on both sides to move closer to the inner side below it and hook the card grooves 11 on both sides of the corresponding lock body 1 of the lower layer, so that the plurality of lock bodies 1 in the upper and lower directions are connected to each other. The position holding mechanism 2 is used to connect with the lock bodies 1 after the two ends of the turnover boxes 3 of the top layer move upward, and keep them in the current position.

[0033] The usage process is as follows:

[0034] Stack multiple turnover boxes 3 up and down and arrange them properly, ensuring that the lock bodies 1 at both ends of each layer of turnover boxes 3 correspond to each other in the up and down directions (distributed on the same straight line). Next, external force causes the lock bodies 1 on the multi-layer turnover boxes 3 to move upward. During the upward movement of the lock bodies, the lock bodies 1 on all turnover boxes 3 except the bottom layer drive the hook assemblies 12 on both sides to rotate and close, and hook the slots 11 on both sides of the lower lock body 1. Finally, the current positions of the lock bodies 1 at both ends of the topmost turnover box 3 are fixed by the position holding mechanism 2, so that the lock bodies on the multi-layer turnover boxes 3 are connected and maintained with each other through the cooperation of the hook assemblies 12 and the slots 11, and finally the multi-layer turnover boxes 3 are firmly and stably connected as a whole, and the operator can easily carry the multi-layer boxes together.

[0035] As a preferred embodiment, Figures 4 to 7 As shown, a seat body 4 is installed at both ends of each layer of the turnover box 3, and the end of the seat body 4 away from the turnover box 3 is provided with a slide 41 that passes through from top to bottom. The lock body 1 is slidably installed in the corresponding slide 41, and the end thereof away from the turnover box 3 leaks out of the slide 41.

[0036] In this embodiment, the design of the seat body 4 can facilitate the good assembly of the lock body 1 thereon, so that the lock body 1 can slide up and down well along the slideway 41 on the seat body 4.

[0037] As a preferred embodiment, Figures 4 to 7 As shown, the hook assembly 12 includes a connecting rod 121 and a vertically arranged hook-shaped hook 122, one end of the connecting rod 121 is hinged to the corresponding side of the lower end of the corresponding lock body 1, one end of the hook 122 is hinged to the side of the corresponding seat body 4 away from the turnover box 3, and the end portion thereof is hinged to the other end of the connecting rod 121, and the other end of the hook 122 is provided with a hook portion, and the hook portions of the hooks 122 on both sides of the same lock body 1 are close to each other, and the lock body 1 moves upward under the action of external force, and drives the connecting rod 121 and the hook 122 on both sides to work together, so that the hooks 122 on both sides are flipped downward and close to each other, and hook the corresponding slot 11 of the lock body 1 in the lower layer.

[0038] In this embodiment, the hook assembly 12 is a linkage structure, and the up and down movement of the lock body 1 drives the connecting rod 121 and the hook 122 to be linked, thereby realizing the flipping of the hook 122 in the vertical plane. The whole design is relatively clever, and the operation is very simple and quick.

[0039] As a preferred embodiment, the upper portion of the turnover box 3 at the uppermost layer is covered with a box cover 31 , and the position holding mechanism 2 is fixed to the upper portion of the box cover 31 .

[0040] In this embodiment, if Figure 1 , 8 As shown, a removable box cover 31 is provided on the turnover box 3 of the top layer, and the turnover boxes 3 of other layers do not need to be provided with box covers 31. The internal objects can be safely stored by covering the turnover boxes 3 of the upper layer. In addition, when the box cover 31 is removed, the position holding mechanism 2 is removed synchronously, so that the position holding mechanism 2 does not affect the normal loading and unloading operations of the turnover boxes 3.

[0041] As a preferred embodiment, the upper and lower ends of the two upper and lower adjacent lock bodies 1 are in contact with each other, and when the lock bodies 1 move upward, the upper ends of the lock bodies 1 extend out of the upper ends of the turnover boxes 3 of the corresponding layer.

[0042] In this embodiment, if Figure 6 , 7As shown, the upper and lower adjacent lock bodies 1 are in contact with each other, so that the lock bodies 1 are tightly connected. When moving, it is only necessary to push the bottom lock body 1 upward to realize the linkage of all the lock bodies 1 in the upper and lower directions. The operation is relatively convenient, quick, time-saving and labor-saving. At the same time, the lock bodies 1 are in contact with each other, so that the upper and lower adjacent lock bodies 1 are more firmly connected after the hook assembly 12 is engaged with the slot 11, and the locking state is relatively stable, which is convenient for the subsequent transportation of the turnover boxes together, and avoids the risk of the turnover box 3 falling during the transportation process due to loose locking.

[0043] As a preferred embodiment, Figure 1 , 8 As shown, the position holding mechanism 2 is a linkage lock, and lock seats 21 are fixed at the two ends of the upper part of the uppermost turnover box 3 corresponding to the positions of the lock body 1, and the two lock core rods of the linkage lock pass through the two lock seats 21 respectively. Under the action of external force, the linkage lock can drive the ends of the two lock core rods to synchronously extend out of the two lock seats 21, or retract into the corresponding lock seats 21. The upper ends of the lock bodies 1 at both ends of the uppermost turnover box 3 are penetrated by lock holes 32 matching the lock core rods. When the lock body 1 of the uppermost layer moves upward to the position where the lock hole corresponds to the lock core rod, the linkage lock can drive the two lock core rods to pass through the two lock seats 21 respectively and extend into the corresponding lock holes 32.

[0044] In this embodiment, the connecting rod lock is a prior art, and its specific structure will not be described here. By unlocking or closing the connecting rod lock, the two lock core rods can be driven to extend or retract, so that the lock core rods can quickly complete the locking or unlocking operation with the lock holes of the lock body 1 at both ends of the top turnover box 3. The operation process is relatively simple and quick.

[0045] Of course, in order for each layer of turnover boxes 3 except the bottom layer to be connected to the position holding mechanism 2, lock holes 32 can be opened on the lock bodies 1 at both ends of these turnover boxes 3.

[0046] As a preferred embodiment, Figure 1 , 8 As shown, a handle 311 is installed on the upper part of the box cover 31.

[0047] In this embodiment, two handles 311 are generally designed and are arranged on both sides of the connecting rod lock respectively, and are rotatably matched with the box cover 31. The handles 311 can be folded and fit on the upper part of the box cover 3, and rotated to a vertical state when needed. The operator applies external force to it to carry multiple layers of turnover boxes 3 at the same time.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
