[0002] A plastic pallet is a logistics unit used in conjunction with logistics equipment such as forklifts and shelves. It can be used to store, load, and transport goods, and is one of the essential logistics equipment in modern logistics warehousing.

[0003] In actual use of the existing plastic pallets, in order to facilitate stacking of the plastic pallets, support blocks are often provided at the bottom of the pallets, and matching slots are opened at the top of the pallets. When stacking the pallets, the support blocks are inserted into the slots to achieve stacking limit. However, in the actual use process, the support blocks are prone to wear, and the support blocks and the slots cannot be fully adapted. Therefore, during the transportation of the stacked plastic pallets, the stacked pallets will shake, which is likely to cause the pallets to be damaged by impact. Therefore, we propose a plastic pallet convenient for stacking. Summary of the Utility Model

[0029] Please refer to Figures 1-3 , the present utility model provides a technical solution: a plastic tray that is easy to stack, including a first plate body 1 and a second plate body 2. A support block 11 is fixed on the top of the first plate body 1, and the top of the support block 11 is fixedly connected to the bottom of the second plate body 2;

[0030] Limit slots 21 are provided on the four sides of the top of the second plate body 2. Limit components 3 are fixed on the four sides of the bottom of the first plate body 1. The limit component 3 includes a fixed shell 31. A movable block 37 movably penetrates through the middle of the bottom of the fixed shell 31. A tapered block 36 is fixed to the inner end of the movable block 37. Wedge-shaped blocks 32 are arranged on both sides of the inner cavity of the fixed shell 31. A push rod 33 is fixed to one side wall of the wedge-shaped block 32. The outer end of the push rod 33 movably penetrates through the fixed shell 31 and is fixedly connected to a pressing plate 34. Fixing plates are fixed on both sides of the top of the fixed shell 31. A spring 35 is fixed to the inner side wall of the fixing plate. The outer end of the spring 35 is fixedly connected to the side wall of the corresponding wedge-shaped block 32;

[0031] During actual use, when stacking trays, first insert the limit component 3 at the bottom of the upper tray into the limit slot 21 of the lower tray. Then, under the action of the self-weight of the tray, the movable block 37 is pressed, so as to push the tapered block 36 to move upward. Thus, the tapered block 36 will push the two wedge-shaped blocks 32 to move outward, realizing pushing the push rod 33 to drive the pressing plate 34 to press against both side walls of the inner cavity of the limit slot 21, so as to ensure a high limit fit degree of the trays after stacking, and further improve the stability of the stacked trays, avoid shaking during transportation, and further avoid damage to the trays caused by excessive shaking.

[0032] Furthermore, an anti-slip pattern 22 is provided at the middle of the top of the second plate body 2. The setting of the anti-slip pattern 22 can prevent the goods from sliding when stacking goods on the tray.

[0033] Even further, a suitable first rubber pad is fixedly glued to the bottom of the fixed shell 31. The setting of the first rubber pad can increase the friction when the bottom tray supports the ground, avoiding sliding.

[0034] It is worth introducing that a suitable second rubber pad 38 is fixedly glued to the outer wall of the pressing plate 34. The setting of the second rubber pad 38 can improve the fitting degree when the pressing plate 34 presses, and further improve the limit effect.

[0035] It should be noted that the top of the wedge-shaped block 32 fits against the top of the inner cavity of the fixed shell 31, so as to ensure the stable movement of the wedge-shaped block 32 when the tapered block 36 pushes the wedge-shaped block 32 to move.

[0036] As Figure 1 and 2 shown; the number of the support blocks 11 is multiple, and the multiple support blocks 11 are evenly distributed in an array between the first plate body 1 and the second plate body 2, so as to improve the stability of the support for the second plate body 2, and at the same time, the spatial distribution is uniform, ensuring that the forklift insertion is not affected.

[0037] The implementation principle of a plastic tray that is convenient for stacking in this application is as follows: In actual use, when it is necessary to stack the trays, first insert the movable block 37 into the corresponding limiting groove 21 for preliminary alignment, and then slightly rotate the plastic tray so that the fixed shell 31 is aligned and inserted, thereby realizing that the limiting component 3 at the bottom of the upper tray is inserted into the limiting groove 21 of the lower tray. Then, under the action of the self-weight of the tray, the movable block 37 is pressed, thereby pushing the tapered block 36 upward. As a result, the tapered block 36 will push the two wedge-shaped blocks 32 outward, realizing the pushing of the push rod 33 to drive the pressing plate 34 to press against the inner cavity side walls of the limiting groove 21, so as to ensure a high limiting fit degree of the trays after stacking, thereby improving the stability of the stacked trays and avoiding shaking during transportation, which is conducive to avoiding damage to the trays caused by excessive shaking.
