Description

Technical Field

[0001] This utility model relates to the field of pallet technology, specifically to an assembled plastic pallet. Background Technology

[0002] Pallets, as a basic logistics carrier, are widely used in warehousing, transportation, and cargo stacking. Their function is to unitize goods, making it easy to load, unload, handle, and store them using machinery. They are an important tool for achieving standardization and efficiency in logistics operations. Currently, the pallets commonly found on the market are mainly divided into wood, metal, and plastic types based on their materials. Among them, plastic pallets are increasingly widely used due to their advantages such as corrosion resistance, easy cleaning, light weight, and recyclability.

[0003] Traditional plastic pallets are mostly manufactured using a one-piece injection molding process. While this type of pallet has good overall structural integrity, it also has obvious limitations: First, the mold cost is high, and once the product size and structure are finalized, it is difficult to adjust flexibly; second, the one-piece molded pallet has a fixed volume, which occupies a lot of space when being collected or stored empty, resulting in high transportation and warehousing costs; third, if a pallet is partially damaged, it often needs to be replaced entirely, resulting in poor maintainability and low economic efficiency.

[0004] To overcome the aforementioned shortcomings, modular plastic pallet designs have emerged. Existing modular pallets are typically manufactured separately from components such as panels and support legs, and then assembled on-site using bolts, clips, or plugs. This design improves the convenience of transportation and storage to some extent and allows for component replacement. However, existing modular structures often have shortcomings in terms of connection stability, overall load-bearing strength, and long-term reliability. 1. The connection between the support column and the top plate and base may not be firm enough, and it is easy to loosen under dynamic load or long-term static pressure; 2. An unreasonable layout of the supporting structure may lead to stress concentration, causing premature local damage; 3. If the cooperation and locking mechanisms between multiple components are too complex, it will reduce assembly efficiency. Utility Model Content

[0005] This utility model provides an assembled plastic pallet. By using a support and lifting mechanism and a connecting mechanism, combined with a locking mechanism, multi-dimensional rigid connection nodes are formed between the support columns, top plate, and load-bearing base. This solves the problem of loosening at the connection points of traditional assembled pallets, significantly improving the overall structural rigidity and torsional resistance of the pallet. It ensures high load-bearing performance and stability under dynamic loading and unloading and long-term static load conditions. The modular design facilitates replacement and maintenance. The detachable structure saves transportation and storage space. When not in use, the pallet can be completely disassembled into independent components such as a flat plate, uprights, and base, greatly reducing the volume occupied and facilitating stacking and storage during logistics transportation. The connecting plate connects and fixes the side support columns and the middle support column, so that multiple support points are no longer isolated. The independent units form a stable frame-like support network, evenly distributing the top load to each support point and the bottom bearing seat, avoiding stress concentration, greatly enhancing the pallet's impact and deformation resistance, and thus extending its service life. All components can be produced in a standardized and modular manner, allowing the pallet to be completely disassembled into flat panels and compact rod and block sets when not in use, reducing storage space and return transport volume. The assembly process is completed through plug-in and snap-fit, requiring no special tools. The operation steps are clear, simple and quick, significantly improving the deployment efficiency before use and the economy of empty-load recovery. If a part of the pallet is damaged due to accident, it is not necessary to scrap the entire pallet; only the damaged standard parts need to be replaced, greatly reducing maintenance costs.
