The mounting column 42 is fixed to the top surface of the No. 1 tray unit 1, and the mounting column 42 passes through the limiting plate 41. A limiting disk 421 is fixed on the top of the mounting column 42. The distance between the mounting column 42 and the end surface of the No. 1 tray unit 1 is equal to the distance between the limiting groove 21 and the end surface of the No. 2 tray unit 2. The reset spring 43 is sleeved on the mounting column 42 and is located between the limiting plate 41 and the limiting disk 421. After adopting the above scheme, when in use, the plastic folding pallet has two usage states, namely, Figure 1 and Figure 2 As shown, when the cargo is a long straight member, use Figure 2 In the state shown, when unfolding pallet unit No. 1 and pallet unit No. 2, first pull up the limit plate 41 to disengage the limit post 411 from the limit slot 21, then rotate pallet unit No. 2 to rotate it 90 degrees, and rotate the limit plate 41 synchronously. When the end faces of pallet unit No. 1 and pallet unit No. 2 are in contact with each other, release the limit plate 41. At this time, the reset spring 43 releases the elastic force, and the limit post 411 is embedded in the limit slot 21 again to lock pallet unit No. 1 and pallet unit No. 2, thereby ensuring the stability of pallet unit No. 1 and pallet unit No. 2 after adjustment. At this time, the plastic folding pallet can be used to place long straight goods without the need to splice multiple plastic pallets, which can greatly reduce the number of plastic pallets used.

[0035] Preferably, by Figures 1 - 3 As shown, in this embodiment, it also includes: a pull ring 412, which is fixed to the top surface of the limiting plate 41. After adopting the above solution, it is easy to pull the limiting plate 41 to move through the set pull ring 412.

[0036] Preferably, by Figures 1 - 3 As shown, in this embodiment, the diameter of the limiting short column 411 is equal to the diameter of the limiting groove 21. After adopting the above scheme, when the limiting short column 411 is embedded in the limiting groove 21, the outer wall of the limiting short column 411 is against the inner wall of the limiting groove 21, further ensuring the stability of the No. 1 tray unit 1 and the No. 2 tray unit 2 after adjustment to avoid shaking.

[0037] Preferably, by Figure 1 and Figure 2As shown in the figure, in this embodiment, it further includes: side limit plates 7. The side limit plates 7 are "L"-shaped members. Side limit plates 7 are fixed to the top ends of the first pallet unit 1 and the second pallet unit 2. After adopting the above solution, the side limit plates 7 provided are used to block the goods, prevent the goods from rolling down, and ensure the safety of the goods.

[0038] Optionally, Figure 1 , Figure 2 and Figure 4 As shown in the figure, in this embodiment, it further includes: locking bolts 8. The side limit plates 7 are fixed to the top ends of the first pallet unit 1 and the second pallet unit 2 by means of the locking bolts 8. After adopting the above solution, the side limit plates 7 of the present utility model are installed by using the locking bolts 8. On the premise of ensuring stable installation, it is also convenient for disassembly, so as to change the installation position of the side limit plates 7 after adjusting the first pallet unit 1 and the second pallet unit 2.

[0039] Preferably, Figure 1 , Figure 2 and Figure 4 As shown in the figure, in this embodiment, a binding opening 71 is processed on the side limit plates 7. After adopting the above solution, through the provided binding opening 71, after the goods are placed on the first pallet unit 1 and the second pallet unit 2, straps can be used to pass through the binding opening 71 to tie up the goods, further improving the stability of the goods.

[0040] Preferably, Figure 1 and Figure 2 As shown in the figure, in this embodiment, it further includes: positioning convex columns 6. Positioning convex columns 6 are fixed to the four corners of the bottom surfaces of the first pallet unit 1 and the second pallet unit 2. Positioning grooves 5 for the positioning convex columns 6 to be embedded are provided on the top surfaces of the first pallet unit 1 and the second pallet unit 2. Through the provided positioning convex columns 6 and positioning grooves 5, when storing plastic pallets, different plastic pallets can be stacked, reducing the floor space. Making the positioning convex columns 6 embedded in the positioning grooves 5 can improve the stacking stability of the plastic pallets.

[0041] Preferably, Figure 1 and Figure 2 As shown in the figure, in this embodiment, the sum of the depth of the positioning groove 5 and the height of the vertical part of the side limit plate 7 is equal to half of the height of the positioning convex column 6. Therefore, after adopting the above design, when stacking different plastic pallets, it is not necessary to disassemble the side limit plates 7. In addition, when the height of the goods is not large, the goods can also be stored in a stacked form.

[0042] The components not described in detail in this article are prior art.

[0043] Working principle and use process of the utility model: When the plastic pallet of the utility model is in use, the plastic folding pallet has two use states, which can be adjusted according to the actual shape of the goods and is suitable for goods of different shapes;

[0044] When the goods are long straight components, unfold the No. 1 pallet unit 1 and the No. 2 pallet unit 2, first pull up the limiting plate 41 to make the limiting short column 411 disengage from the limiting groove 21, then rotate the No. 2 pallet unit 2 to make the No. 2 pallet unit 2 rotate 90 degrees, and rotate the limiting plate 41 synchronously. When the end faces of the No. 1 pallet unit 1 and the No. 2 pallet unit 2 are in contact, release the limiting plate 41. At this time, the reset spring 43 releases the elastic force, and the limiting short column 411 is embedded in the limiting groove 21 again, locking the No. 1 pallet unit 1 and the No. 2 pallet unit 2 to ensure the stability of the No. 1 pallet unit 1 and the No. 2 pallet unit 2 after adjustment. At this time, the plastic folding pallet can be used to place long straight goods without the need to splice multiple plastic pallets, which can greatly reduce the number of plastic pallets used;

[0045] By setting the positioning boss 6 and the positioning groove 5, different plastic pallets can be stacked when storing plastic pallets to reduce the occupied space. The positioning boss 6 is embedded in the positioning groove 5, which can improve the stability of the stacking of plastic pallets. In addition, when the height of the goods is not large, the goods can also be stored in a stacked form.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
