[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figures 1-6 The utility model provides a technical solution: a plastic pallet with a built-in anti-collision buffer structure, including a lower pallet 1, an upper pallet 2, support legs 3, a card slot 4, a card hole 5, a connecting hole 1 6, a support block 7, a connecting hole 2 8, a support plate 1 9, a connecting rod 10, a support plate 2 11, and a buffer spring 12.

[0029] The lower tray 1 is a box-shaped structure with an open upper surface. An upper tray 2 is arranged above the lower tray 1. The upper tray 2 is a plate-shaped structure, and the upper tray 2 is the same size as the lower tray 1. The surface of the upper tray 2 is provided with square hollow holes. The lower tray 1 and the upper tray 2 together constitute a tray structure. The surfaces of the upper tray 2 and the lower tray 1 are provided with a supporting structure. The supporting structure is used to lock and store multiple trays while preventing air pressure from affecting the separation of the trays. The supporting structure includes supporting legs 3. The supporting legs 3 are rectangular structures. The upper surface of the supporting legs 3 is provided with a supporting structure. The surface is fixedly installed on the lower surface of the lower tray 1. The lower surface of the lower tray 1 is rectangularly distributed with 9 support legs 3. The outer surface of the support leg 3 is provided with a U-shaped groove, and the groove on the surface of the support leg 3 is set through the lower surface of the support leg 3. The upper surface of the lower tray 1 is correspondingly provided with a card slot 4. The card slot 4 is engaged with the support leg 3, and the depth of the card slot 4 is less than the height of the support leg 3. The card slot 4 is fixedly installed on the upper surface of the lower tray 1. The top of the card slot 4 is aligned with the card hole 5. The card hole 5 is set through the surface of the upper tray 2, and the card hole 5 is the same size as the card slot 4;

[0030] like Figure 1 、 Figure 2 and Figure 6 As shown, when using this device, the pallet structure composed of the lower pallet 1 and the upper pallet 2 is used to support and transport the goods. When the pallet is idle, the support legs 3 are inserted into the surface of another pallet, so that the support legs 3 pass through the card holes 5 and engage with the card slots 4, so that stacking between the two pallet structures is prevented, and there is a gap between the pallet structures, and a through U-shaped groove is provided on the lower surface of the support leg 3. When the support leg 3 is engaged with the card slot 4, the groove on the surface of the support leg 3 allows the card slot 4 to always be connected to the external air, avoiding the formation of low pressure inside the card slot 4, adsorbing the support leg 3, thereby avoiding the support leg 3 being adsorbed inside the card slot 4 and unable to be pulled out, affecting the use of the pallet structure.

[0031] A connecting structure is provided between the lower tray 1 and the upper tray 2. The connecting structure allows the lower tray 1 and the upper tray 2 to be detachably assembled to adapt to different usage scenarios. The connecting structure includes a connecting hole 1 6, which is provided through the surface of the upper tray 2 and has an inner wall provided with a thread. The cross section of the connecting hole 1 6 is T-shaped. A support block 7 is provided below the connecting hole 1 6. The support block 7 is fixedly mounted on the surface of the lower tray 1. The four support blocks 7 form a cross-shaped structure on the surface of the lower tray 1. The surface of the support block 7 is provided with a connecting hole 2 8. The inner wall of the connecting hole 2 8 is a threaded structure. The connecting hole 1 6 and the connecting hole 2 8 are connected by bolts.

[0032] like Figure 3 、 Figure 4 and Figure 5 As shown, when the lower pallet 1 and the upper pallet 2 are separated, the lower pallet 1 alone can be used as a pallet to support small-volume goods. The small-volume goods are placed on the open upper surface of the lower pallet 1. When the goods are larger, the upper pallet 2 is placed above the lower pallet 1, and the connecting hole 1 6 is connected to the connecting hole 2 8 on the surface of the lower support block 7 by bolts, so that the upper pallet 2 is fixed to the upper surface of the lower pallet 1. At this time, large-volume goods can be placed on the flat surface of the upper pallet 2 for transportation, which increases the application occasions of the pallet.

[0033] The surface of the lower tray 1 is provided with a buffer structure, which buffers and reduces shock on the surface of the lower tray 1 to protect the tray. The buffer structure includes a support plate 9, which is provided on the side surface of the lower tray 1. A connecting rod 10 is fixedly connected to the surface of the support plate 9. The other end of the connecting rod 10 passes through the side surface of the lower tray 1 and is connected to a support plate 2 11. The connecting rod 10 is slidably connected to the side surface of the lower tray 1. A buffer spring 12 is provided on the outer surface of the connecting rod 10. One end of the buffer spring 12 is fixed to the outer surface of the lower tray 1, and the other end of the buffer spring 12 is fixed to the surface of the support plate 9.

[0034] like Figure 1 and Figure 4 As shown, the goods are placed on the surface of the pallet structure for supported transportation. When the pallet structure is impacted by external force, the support plate 1 9 drives the connecting rod 10 to slide inward and compress the buffer spring 12. A buffer is formed between the buffer spring 12 and the connecting rod 10, thereby buffering and shock-absorbing the external force, playing a force unloading role, and providing buffering protection for the pallet and goods. Similarly, the support plate 2 11 can provide buffering protection for small-volume goods inside the lower pallet 1.

[0035] Working principle: When using the plastic pallet with a built-in anti-collision buffer structure, the support leg 3 of one pallet is passed through the card hole 5 of the other pallet and engaged with the card slot 4. Since a U-shaped groove is set through the surface of the support leg 3, the card slot 4 is always connected to the air, avoiding the support leg 3 being adsorbed in the card slot 4 due to air pressure. When the lower pallet 1 and the upper pallet 2 are separated, the lower pallet 1 can support small-volume goods. After the lower pallet 1 and the upper pallet 2 are connected by bolts, large-volume goods can be supported on the upper surface of the upper pallet 2. When the pallet structure is impacted by external force, a buffer is formed between the support plate 1 9, the support plate 2 11 and the buffer spring 12 to provide buffering protection for the goods, thereby increasing the overall practicality.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
