Description

Technical Field

[0001] This utility model relates to the field of plastic pallet technology, and more specifically, to a plastic pallet with a limiting function. Background Technology

[0002] Plastic pallets are logistics units used in conjunction with forklifts, racks, and other logistics equipment. They are used to store, load, and transport goods and are an indispensable piece of logistics equipment in modern warehousing. The emergence of plastic pallets is in line with environmental protection needs; using plastic pallets instead of wooden pallets is the best way to reduce damage to forests. However, when using existing plastic pallets, there is a lack of suitable limiting and protection mechanisms for different stacking heights after goods are stacked, which affects safety. Furthermore, the installation efficiency of the bottom limiting mechanism corresponding to the pallet body is low, lacking a suitable quick-installation mechanism. In addition, the assembly efficiency between multiple limiting mechanisms is low, lacking a suitable quick-connect locking mechanism. Utility Model Content

[0008] The present invention is further provided that each of the multiple L-shaped locking rods is provided with an anti-slip rubber sleeve corresponding to the locking groove to ensure a tight and anti-slip effect.

[0009] The present invention is further configured such that a retaining ring is fitted on the outer end face of each of the plurality of L-shaped retaining rods, and the retaining ring is threadedly connected to the L-shaped retaining rod to achieve anti-dislodgement locking.

[0010] The present invention is further configured such that a first connecting plate and a second connecting plate are detachably provided between two adjacent limiting frames.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a plastic tray with a limiting function, which has the following beneficial effects:

[0015] 1. Through its detachable and stackable multi-layered limit frame design, this plastic pallet achieves flexible height control and protection for stacked goods. Users can choose to install one or more limit frames according to the actual stacking height of the goods, effectively preventing high-rise goods from tilting, slipping, or collapsing during transportation or storage. This modular limiting method greatly enhances the pallet's versatility and adaptability, providing stable lateral support and enclosure protection for stacks of different sizes, ensuring the stability and safety of stacked goods.

[0016] 2. The design of the first or second connecting plate allows for detachable connections between multiple limit frames, providing high flexibility and adjustability. When stacking multiple limit frames, users can choose to use a single first connecting plate or two symmetrical second connecting plates to connect adjacent layers, depending on actual space and structural requirements. The use of positioning rods, positioning holes, and threaded positioning rings enables quick and secure installation and locking of the connecting plates, ensuring the structural integrity and stability of the entire limit frame assembly and resulting in a reliable and uniform connection of the stacked limit frames.

[0017] 3. The locking plate design allows for secure locking of the limit frame to the tray by aligning the mounting block at the lower end of the limit frame with the mounting slot on the tray, inserting the locking rod through the side locking hole, and connecting the locking rods on the same side with the locking plate. This externally locks the limit frame firmly onto the tray. The rotatable L-shaped locking rod engages with the slot on the locking plate, and anti-slip rubber sleeves and threaded retaining rings provide further anti-slip and anti-dislodgement reinforcement, forming a highly efficient and reliable multi-layered locking mechanism. This method is not only simple and quick to operate but also provides strong locking force, effectively preventing the limit frame from loosening or shifting under external impact, ensuring the stability of the basic connection.
