Description

Technical Field

[0001] This utility model relates to the field of pallet technology, and in particular to a plastic pallet splicing structure. Background Technology

[0002] Traditional one-piece plastic pallets, while structurally stable, are heavy, increasing raw material consumption and production costs. They also consume more energy during empty pallet handling and turnover, making them particularly unsuitable for scenarios requiring frequent manual handling. Furthermore, the one-piece structure cannot be flexibly adjusted to load-bearing requirements; when a part is damaged, the entire pallet must be replaced, resulting in resource waste. While modular plastic pallets address some flexibility issues, their splicing structure design is often flawed. Common splicing methods rely heavily on bolts, rivets, and other fasteners, making assembly and disassembly cumbersome, requiring tools, increasing manual operation time and labor intensity, and reducing work efficiency. Moreover, fasteners are prone to loosening or corrosion over time, affecting connection stability and causing the pallet to wobble or even separate when carrying heavy loads, posing safety hazards. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing split-type pallet guide and positioning structures, which suffer from insufficient precision, leading to misalignment during assembly and assembly difficulties. Furthermore, the lack of effective auxiliary positioning devices during stacking causes pallets to easily shift or misalign, affecting stacking neatness and potentially causing collapses due to unstable stacking, thus increasing warehouse management risks. Simultaneously, most pallets fail to balance lightweight design with structural strength, either sacrificing weight for strength or reducing load-bearing capacity due to lightweight design, making it difficult to meet the comprehensive usage needs of various scenarios.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A plastic pallet splicing structure includes a base with a pallet mounted on its upper end. The base includes a grid-shaped reinforcing rib with a plurality of weight-reducing holes evenly spaced on it. A plurality of square guide members are also evenly spaced on the grid-shaped reinforcing rib, each square guide member having a snap-fit ​​nose on both sides. The pallet includes a flat plate with a plurality of square insertion slots evenly spaced on its bottom. Each square insertion slot has a snap-fit ​​nose locking hole on both sides. A plurality of weight-reducing ventilation holes are also evenly spaced on the flat plate. Adsorption magnets are installed at the four corners of the base, inside the square guide members. The grid-shaped reinforcing rib enhances the structural strength of the base, while the weight-reducing holes and ventilation holes effectively reduce the overall weight, lowering material costs and transportation energy consumption. The coordinated design of the square guide members with the square insertion slots and the snap-fit ​​noses with the snap-fit ​​nose locking holes enables rapid splicing and fixing of the base and pallet. The corner magnets provide basic positioning for stacking. The overall structure balances structural stability, lightweight design, and ease of assembly.

[0006] Furthermore, the square guide is assembled and connected with the square insertion slot, and the snap-fit ​​nose is assembled and connected with the snap-fit ​​nose locking hole for locking and fixing. This clarifies the assembly relationship between the square guide and the square insertion slot, and between the snap-fit ​​nose and the snap-fit ​​nose locking hole, ensuring precise alignment during assembly and avoiding installation deviations. The locking and fixing function of the snap-fit ​​nose and the snap-fit ​​nose locking hole can prevent relative displacement between the base and the tray during use, improve the connection reliability of the overall structure, and ensure the stability of the tray when carrying items.

[0007] Furthermore, the adsorption magnets are fixed to the four corners of the base with glue. When the pallets are stacked, they can be used for basic positioning. The use of glue to fix the adsorption magnets is simple and reliable, reducing assembly difficulty. The basic positioning function of the adsorption magnets during stacking can reduce misalignment between pallets, making the stacking process smoother and more efficient, while preventing pallets from shifting due to slight collisions after stacking.

[0008] Furthermore, the height of the square guide is adapted to the depth of the square insertion slot, and the gap between the two is controlled within the range of 0.1-0.3mm. This ensures accurate guidance and stable fit during splicing. The matching of the height of the square guide with the depth of the square insertion slot, and the control of the gap within 0.1-0.3mm, not only ensures accurate guidance during splicing and avoids shaking caused by excessive gaps, but also reduces assembly resistance, making the splicing process more labor-saving.

[0009] Furthermore, the snap-fit ​​nose is made of elastic plastic material, and its end is provided with a guide slope with an inclination angle of 30°-45°. During the splicing process of the square guide and the square insertion slot, elastic deformation can be generated by the compression of the guide slope, which facilitates the snap-fit ​​nose to smoothly engage with the snap-fit ​​nose lock hole. The snap-fit ​​nose made of elastic plastic material has good deformation ability. Combined with the 30°-45° guide slope, it can smoothly undergo elastic deformation by compression during splicing, which facilitates the snap-fit ​​nose to engage with the snap-fit ​​nose lock hole, reduces the force required for splicing operation, and improves assembly efficiency. At the same time, the snap-fit ​​nose after elastic deformation can be tightly engaged in the lock hole, enhance the locking effect, prevent accidental disengagement during use, and ensure the firmness of the connection.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. Double-layer assembly pallets enhance the stability of the pallet's bottom structure. The overall structure is reinforced with a grid-shaped rib to ensure load-bearing strength, making it suitable for heavy-duty transportation scenarios. The lightweight design (weight-reducing holes and ventilation holes) reduces energy consumption when handling empty pallets, making it suitable for frequent turnover scenarios. The ease of splicing and stacking (clamping and magnetic positioning) improves warehouse stacking efficiency, meeting the comprehensive usage needs of multiple scenarios such as logistics transportation and warehousing.

[0012] 2. The combination of grid-shaped reinforcing ribs and lightweight holes ensures strength while reducing raw material consumption and lowering production costs; the snap-fit ​​splicing eliminates the need for additional fasteners, and magnetic positioning simplifies the palletizing process, reducing manual operation time and labor intensity, and lowering assembly and warehousing management costs; the overall structural stability and durability also extend the lifespan of the pallet and reduce repeated procurement expenditures.

[0013] 3. The tight fit between the snap-fit ​​nose and the lock hole, along with the precise gap control of the guide components, prevents loosening or displacement after assembly, thus preventing the carried items from slipping off; the positioning effect of the magnets during stacking reduces the risk of pallet shifting and lowers the risk of stack collapse; the convenient operation and secure locking of the elastic snap-fit ​​not only reduces the rate of operational errors during assembly but also ensures structural stability during long-term use, comprehensively improving the safety of the operation process.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Combination Figure 1-3As shown, a plastic pallet splicing structure includes a base 1, with a pallet 2 mounted on the upper end of the base 1. The base 1 includes a grid-shaped reinforcing rib 11, with a plurality of weight-reducing holes 12 evenly arranged on the grid-shaped reinforcing rib 11, and a plurality of square guide members 13 evenly arranged on the grid-shaped reinforcing rib 11. Each square guide member 13 has a latching nose 14 on both sides. The pallet 2 includes a flat plate 21, with a plurality of square insertion slots 22 evenly arranged on the bottom of the flat plate 21, and each square insertion slot 22 has a latching nose locking hole 23 on both sides. The plate 21 has several weight-reducing and ventilation holes 24 arranged at equal intervals. The four corners of the base 1 are equipped with magnets 3 inside the square guide 13. The structural strength of the base is improved by the grid-shaped reinforcing ribs. The weight-reducing and ventilation holes effectively reduce the overall weight, reduce material costs and transportation energy consumption. The design of the square guide and the square plug-in slot, the buckle nose and the buckle nose locking hole enables the quick splicing and fixing of the base and the pallet. The magnets at the four corners provide basic positioning for stacking. The overall structure takes into account structural stability, lightweight and easy splicing.

[0020] The square guide 13 is assembled and connected to the square insertion slot 22, and the snap-fit ​​nose 14 is assembled and connected to the snap-fit ​​nose locking hole 23 for locking and fixing. This clarifies the assembly relationship between the square guide 13 and the square insertion slot, and between the snap-fit ​​nose and the snap-fit ​​nose locking hole, ensuring precise alignment during assembly and avoiding installation deviations. The locking and fixing function of the snap-fit ​​nose and the snap-fit ​​nose locking hole prevents relative displacement between the base and the tray during use, improving the overall structural connection reliability and ensuring the stability of the tray when carrying items. The adsorption magnet 3 is fixed to the four corners of the base 1 with glue. During pallet stacking, it can be used for basic positioning. Using glue to fix the adsorption magnet is simple and reliable, reducing assembly difficulty. The basic positioning function of the adsorption magnet during stacking reduces misalignment between trays, making the stacking process smoother and more efficient, while preventing the tray from shifting due to slight collisions after stacking. The height of the square guide 13 is adapted to the depth of the square insertion slot 22, and the gap between them is controlled within the range of 0.1-0.3mm. Within the enclosure, to ensure precise guidance and stable fit during assembly, the height of the square guide component matches the depth of the square insertion slot, with the gap controlled at 0.1-0.3mm. This ensures precise guidance during assembly, preventing wobbling caused by excessive gaps, and reduces assembly resistance, making the assembly process easier. The snap-fit ​​nose 14 is made of elastic plastic, with a guide bevel at its end at an angle of 30°-45°. During the assembly process between the square guide component 13 and the square insertion slot 22, the guide component can guide the movement of the square guide component 13 through the square insertion slot 22. The pressure of the inclined surface generates elastic deformation, which facilitates the snap-nose 14 to smoothly engage with the snap-nose lock hole 23. The snap-nose made of elastic plastic has good deformation ability. With the 30°-45° guide inclined surface, it can smoothly undergo elastic deformation through pressure during splicing, which makes it easy for the snap-nose to engage with the snap-nose lock hole, reduces the force required for splicing operation, and improves assembly efficiency. At the same time, the snap-nose after elastic deformation can be tightly engaged in the lock hole, enhancing the locking effect, preventing accidental disengagement during use, and ensuring the firmness of the connection.
