Description

Technical Field

[0001] The utility model relates to the field of plastic pallets, and specifically relates to an up-and-down combined plastic pallet. Background Art

[0002] As is well known, a plastic pallet is a logistics unit used in conjunction with logistics equipment such as forklifts and shelves, mainly for storing, loading, and transporting goods. A combined plastic pallet is a plastic pallet formed by splicing two upper and lower components through snap-fasteners or other means. The advantage of the up-and-down combined plastic pallet is that local components can be conveniently replaced locally after being damaged, without the need to replace the entire pallet, greatly reducing the cost of using the pallet.

[0003] Regarding the above problems, a kind of up-and-down combined plastic pallet with the Chinese patent publication number: CN218641337U, through the design of multiple connecting bolts, is convenient for the disassembly and assembly between the support seat and the connecting block. Therefore, when the pallet or the support seat is damaged, they can be replaced separately according to needs, without the need to replace the whole pallet, effectively avoiding the problem of waste.

[0004] Although the comparative patent solves the problem of large waste caused by the need to replace the whole when the upper pallet or the support seat is damaged, the device realizes the disassembly and assembly of the mounting plate, the pallet, and the support seat through the connection of bolts. Since the bolts will reverse and loosen under strong vibration, the stability of the device is greatly reduced.

[0005] In view of the above related technologies, the device has the defect that the bolts will reverse and loosen under strong vibration, thus greatly reducing the stability of the device. Content of the Utility Model

[0024] In order to make the above objects, features and advantages of the utility model more obvious and understandable, the following detailed description of the specific embodiments of the utility model will be given in conjunction with the accompanying drawings of the specification.

[0025] Embodiment 1

[0026] Refer to Figures 1-4, which is the first embodiment of the present utility model, provides an up-and-down combined plastic tray, including a bottom tray 1, a tray base 4 and a top tray 7. A clamping post 8 is fixedly connected to the top of the bottom tray 1. A groove 9 is formed in the outer wall of the clamping post 8. A spring 10 is fixedly connected to the inner wall of the groove 9. One end of the spring 10 is fixedly connected to a clamping block 11. A channel 12 is formed in the top of the top tray 7. A clamping groove 13 is formed in the inner wall of the channel 12. A support 14 is fixedly connected to the top of the top tray 7. A support plate 15 is fixedly connected to the top of the support 14. A threaded channel 16 is formed in the top of the support plate 15. A threaded column 17 is threadedly sleeved in the inner wall of the threaded channel 16. A lifting groove 18 is formed in the bottom of the threaded column 17.

[0027] The clamping groove 13 is movably clamped with the clamping block 11. The clamping post 8 extends into the channel 12, and the outer wall of the clamping post 8 is slidably connected to the channel 12. Through the clamping of the clamping groove 13 and the clamping block 11, the clamping block 11 plays a role in limiting and fixing the top tray 7, so that the top tray 7 and the bottom tray 1 are installed together.

[0028] The outer wall of the clamping block 11 is slidably connected to the inner wall of the groove 9, and the shape of the clamping block 11 is a "right trapezoid" structure. When a relatively large force is applied to the inclined surface of the clamping block 11, the clamping block 11 will move into the groove 9. The bottom of the clamping block 11 is a straight surface, which can play a role in limiting, so that the top tray 7 will not automatically separate from the bottom tray 1.

[0029] During the use process, in step one, place the top tray 7 on the bottom tray 1 and move the top tray 7 downward. The inclined surface of the clamping block 11 will move into the groove 9 under the resistance of the inner wall of the channel 12. When the clamping block 11 moves to one side of the clamping groove 13, it will be reset by the elastic force of the spring 10. One end of the clamping block 11 will extend into the clamping groove 13. Through the clamping of the clamping groove 13 and the clamping block 11, the clamping block 11 plays a role in limiting and fixing the top tray 7, so that the top tray 7 and the bottom tray 1 are installed together;

[0030] In step two, when it is necessary to disassemble the bottom tray 1 and the top tray 7, rotate the threaded column 17. The bottom of the threaded column 17 will move downward in the channel 12. Then the threaded column 17 will be sleeved on the clamping post 8 through the lifting groove 18. Subsequently, the inclined surface of the clamping block 11 will be blocked by the inner wall of the lifting groove 18 and move into the groove 9. Then the clamping block 11 will be separated from the clamping groove 13, and then the bottom tray 1 and the top tray 7 can be separated.

[0031] Embodiment 2

[0032] Refer to Figures 1-4, which is the second embodiment of the present utility model. A threaded groove 2 is provided at the bottom of the bottom tray 1. A threaded block 6 is fixedly connected to the top of the tray base 4. The outer wall of the threaded block 6 is threadedly connected to the inner wall of the threaded groove 2. By the threaded connection between the threaded block 6 and the threaded groove 2, the tray base 4 can be installed at the bottom of the bottom tray 1.

[0033] A first magnetic plate 3 is fixedly connected to the bottom of the bottom tray 1. The shape of the first magnetic plate 3 is a "ring" - shaped structure. A second magnetic plate 5 is fixedly sleeved on the outer wall of the tray base 4. The first magnetic plate 3 and the second magnetic plate 5 are identical in shape and size. When the tray base 4 is installed on the bottom tray 1, the first magnetic plate 3 and the second magnetic plate 5 will come into contact.

[0034] The shape of the second magnetic plate 5 is the same as that of the first magnetic plate 3, and the first magnetic plate 3 and the second magnetic plate 5 attract each other. Since both the first magnetic plate 3 and the second magnetic plate 5 have relatively large magnetic forces, the first magnetic plate 3 and the second magnetic plate 5 will be attracted to each other, and the tray base 4 is limited and fixed through the action of the magnetic force.

[0035] During use, when the tray base 4 is installed on the bottom tray 1, the first magnetic plate 3 and the second magnetic plate 5 will come into contact. Since both the first magnetic plate 3 and the second magnetic plate 5 have relatively large magnetic forces, the first magnetic plate 3 and the second magnetic plate 5 will be attracted to each other, and the tray base 4 is limited and fixed through the action of the magnetic force.

[0036] It should be noted that the above - mentioned embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
