Description

Technical Field

[0001] The utility model relates to the technical field of pallets, in particular to a combined plastic pallet. Background Art

[0002] Plastic pallets are used to facilitate cargo loading and unloading, transportation, storage and distribution. They are composed of a load surface that can carry a certain number of items and a forklift socket.

[0003] For example, a plastic pallet with patent announcement number CN221050245U includes a pallet body, which is integrally formed, with sockets provided at the middle positions of both sides of one end of the pallet body, forklift ports provided at the bottom of both ends of one side of the pallet body, and a plurality of uniformly distributed rigid cavities provided in the pallet body, wherein the sockets are located between two adjacent rigid cavities. The above document still has deficiencies. When in use, the integrally formed pallet body greatly enhances the supporting performance. The column formed by the side walls of the forklift port and the socket is close to the edge of the pallet body, which can further improve the supporting performance of the pallet body. In addition, the steel pipe increases the load-bearing capacity and rigidity of the pallet body. The plastic pallet can be greatly improved to protect the safety of the product to the maximum extent. Therefore, the supporting strength of the pallet can be improved. However, the plastic pallet is easy to break when subjected to external force, especially when the fork shovel is inserted into the bottom of the pallet to lift the pallet. The plastic pallet is not strong enough, which can easily lead to damage to the plastic pallet. After the bottom of the plastic pallet is damaged, the entire plastic pallet is often thrown away directly, which causes great waste. At the same time, when the forklift lifts the plastic speed plate, it tilts the plastic speed plate toward the forklift. The goods on the plastic pallet lean on the forklift arm and will not fall off from the front and back directions of the plastic pallet. However, when the goods are subjected to left and right forces, the goods are easy to fall off from the left and right directions of the plastic pallet. Utility Model Content
