With the above structure, the fixing plate is provided to coordinate with the fixing rod, spring, and limit frame.

[0004] The above patent has the following problems:

[0005] The tops of existing plastic pallets are flat, making it easy to take goods out. However, the limit frame in the above patent is higher than the pallet body, which is not convenient for taking goods out, and the limit height of the limit frame is also insufficient. Therefore, we have launched a plastic pallet with a built-in limit structure. Utility Model Content

[0006] The purpose of the utility model is to provide a plastic pallet with a built-in limiting structure, which can automatically limit the cargo when the pallet is lifted by a forklift, and the limiting position is relatively high, which is also convenient for taking the cargo, so as to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A plastic pallet with a built-in limiting structure includes a pallet body, corner support blocks are fixedly provided at the four corners of the bottom of the pallet body, a side support block is fixedly provided at the middle of the bottom edge of the pallet body, a pressure plate is provided at the bottom of the pallet body, a limiting frame is provided on the outside of the pallet body, a connecting plate is provided between the side support block and the corner support block, and the two sides of the connecting plate are respectively fixedly connected to the side walls of the pressure plate and the bottom of the limiting frame, a reset structure is provided between the four corners of the pressure plate and the pallet body, and a limiting mechanism is provided between the limiting frame and the pallet body.

[0009] Furthermore, the reset structure includes a movable rod, and circular grooves are provided at the four corners of the pressure plate at the bottom of the tray body. The movable rod is slidably arranged in the circular groove, and the lower end of the movable rod is fixedly connected to the pressure plate. The wall of the movable rod is provided with a strip hole, and a fixed rod is slidably provided in the strip hole. The two ends of the fixed rod are fixedly connected to the circular groove, and a spring is fixed at the top of the circular groove.

The goods are first stacked on the pallet body. After stacking is completed, the steel fork of the forklift is inserted from below between the side support block and the corner support block, and the steel fork of the forklift is located between the pressure plate and the connecting plate. When the steel fork rises, it drives the pressure plate close to the pallet body, and the pressure plate drives multiple movable rods to squeeze the spring. The pressure plate drives the limiting frame to rise through the connecting plate. The arc surface of the limiting frame pushes the multiple limiting plates to rotate to a vertical state through the movable connecting parts. At this time, the multiple limiting plates can automatically limit the goods when the forklift lifts the pallet, and the limiting position is relatively high, which is also convenient for taking the goods.

[0022] 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.

[0023] See also Figures 1 to 4 , the utility model provides a technical solution:

[0024] A plastic pallet with a built-in limiting structure includes a pallet body 1, corner support blocks 5 are fixedly provided at the four corners of the bottom of the pallet body 1, a side support block 6 is fixedly provided at the middle of the bottom edge of the pallet body 1, a pressure plate 7 is provided at the bottom of the pallet body 1, a limiting frame 4 is provided on the outside of the pallet body 1, a connecting plate 8 is provided between the side support block 6 and the corner support block 5, and the two sides of the connecting plate 8 are respectively fixedly connected to the side walls of the pressure plate 7 and the bottom of the limiting frame 4, and the upper end of the inner side wall of the limiting frame 4 is provided with an arc surface, which reduces the friction between the limiting frame 4 and the limiting plate.

[0025] A reset structure is provided between the four corners of the pressure plate 7 and the tray body 1. The reset structure includes a movable rod 11. Circular grooves are provided at the four corners of the pressure plate 7 at the bottom of the tray body 1. The movable rod 11 is slidably set in the circular groove. The lower end of the movable rod 11 is fixedly connected to the pressure plate 7. A strip hole is provided on the rod wall of the movable rod 11. A fixed rod 10 is slidably provided in the strip hole. Both ends of the fixed rod 10 are fixedly connected to the circular groove. A spring 9 is fixedly provided at the top of the circular groove. The spring 9 is always in a compressed state. The pressure plate and the limit frame can be reset through the reset structure.

[0026] A limiting mechanism is provided between the limiting frame 4 and the pallet body 1, and the limiting mechanism includes a limiting plate 2. The limiting plate 2 is vertically slidably arranged between the limiting frame 4 and the pallet body 1, and the lower end of the limiting plate 2 is rotatably connected to the lower end of the side wall of the pallet body 1 through a movable connecting part. When the steel fork of the forklift lifts the plastic pallet, the limiting mechanism can drive multiple limiting plates to stand upright and limit the goods. The limiting plate is long, so it can limit goods stacked higher.

[0027] Reset blocks 3 are fixedly provided on the side walls around the pallet body 1. After the steel forks of the forklift leave the bottom of the pallet body 1, the reset blocks 3 push the corresponding limit plates to rotate to a horizontal state, thereby facilitating the removal of goods. The reset blocks 3 are wear-resistant rubber blocks with good wear resistance and long service life.

[0028] When in use, first stack the goods on the pallet body 1. After stacking is completed, insert the steel fork of the forklift from below between the side support block 6 and the corner support block 5, and the steel fork of the forklift is located between the pressure plate 7 and the connecting plate 8. When the steel fork rises, it drives the pressure plate 7 close to the pallet body 1, and the pressure plate 7 drives multiple movable rods 11 to squeeze the spring 9. The pressure plate 7 drives the limit frame 4 to rise through the connecting plate 8. The curved surface of the limit frame 4 pushes the multiple limit plates 2 to rotate to a vertical state through the movable connecting parts. At this time, the multiple limit plates 4 can automatically limit the goods when the forklift lifts the pallet, and the limit position is high, which is also convenient for taking the goods.

[0029] 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.
