Description

Technical Field

[0001] The present invention relates to the technical field of logistics transportation equipment, and particularly to a square plastic logistics pallet with high load-bearing capacity, anti-bending, anti-compression and anti-slip properties. Background Art

[0002] In the context of today's globalized economy, the logistics industry has become a key link connecting various aspects of production, circulation and consumption. Its efficient operation plays a crucial supporting role in the stable growth of the national economy. In recent years, with the rapid development of e-commerce, the continuous upgrading of the manufacturing industry and the advancement of supply chain management towards refinement, the business volume of the logistics industry has shown an explosive growth trend. In this context, as a basic unitized appliance in the processes of logistics transportation, storage and handling, the performance of logistics pallets directly affects the overall efficiency, cost and safety of logistics operations.

[0003] Traditional wooden pallets are prone to moisture absorption, deformation, cracking, have limited anti-bending and anti-compression capabilities when carrying heavy objects, and have a short service life. Plastic pallets have relatively weak strength, are difficult to handle long-term storage and handling of heavy goods, and have insufficient anti-bending performance. Metal pallets, although having high strength, are heavy in weight, increase transportation costs and are inconvenient to operate, and are prone to damaging goods and equipment. Moreover, most existing pallets lack effective anti-slip designs, and goods are prone to sliding and tipping during transportation due to vehicle acceleration, deceleration, turning or bumping, resulting in damage to goods and endangering transportation safety. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems, and a square plastic logistics pallet with high load-bearing capacity, anti-bending, anti-compression and anti-slip properties is proposed.

[0005] To achieve the above purpose, the following technical solutions are adopted: A square plastic logistics pallet with high load-bearing capacity, anti-bending, anti-compression and anti-slip properties, comprising an upper plate assembly and a lower plate assembly. The upper plate assembly consists of a tray and nine support foot columns. The lower plate assembly consists of a bottom plate and nine support foot columns. A support plate is integrally provided at the edge of the bottom plate between two adjacent support foot columns. First reinforcing rib groups are uniformly provided inside the tray and the bottom plate. Second reinforcing rib groups are provided inside each support foot column. Reinforcing columns are provided inside the tray and the bottom plate. Steel pipes are provided inside the reinforcing columns. Mounting holes are respectively provided on the sides of the upper plate assembly and the lower plate assembly. Weight-reducing holes are provided on the bottom surface of the bottom plate. Third reinforcing rib groups are provided on the bottom surface of the support plate. Mounting grooves are uniformly provided at the top, inside of the tray and at the bottom of the bottom plate. Anti-slip devices are provided inside the mounting grooves.

[0006] Preferably, the upper plate assembly and the lower plate assembly are connected by a hot-melt method.

[0007] Preferably, the lower plate assembly has a cross-shaped structure. The side surface of the support plate has a certain inclination angle. The bottom surface of the support plate is provided with a weight-reducing groove, and a third reinforcing rib group is arranged in the weight-reducing groove. The third reinforcing rib group is triangular.

[0008] Preferably, the reinforcing ribs of the first reinforcing rib group and the second reinforcing rib group are criss-crossed. The first reinforcing rib group and the second reinforcing rib group are connected to the upper plate assembly and the lower plate assembly by integral injection molding.

[0009] Preferably, the reinforcing columns are hollow. The reinforcing columns are arranged in a crosswise pattern within the tray and the bottom plate. The reinforcing columns within the tray are horizontal, and the reinforcing columns within the bottom plate are vertical.

[0010] Preferably, the number and positions of the mounting holes match those of the reinforcing columns, and a plug is provided in each mounting hole.

[0011] Preferably, insertion holes are provided at both ends of the reinforcing columns and on the plugs, and pins are provided in the insertion holes.

[0012] Preferably, the front end of the pin is a conical plug, and the end of the pin is flat.

[0013] Preferably, the anti-slip device includes an anti-slip pad and a base. The anti-slip pad is made of polyphenylene ether material, and the base is made of polypropylene material. The thickness of the anti-slip device is higher than the depth of the installation groove.

[0014] Preferably, the side surface of the support foot column is provided with protrusions, and the top surface of the tray is provided with convex patterns.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The cross-shaped structure design enhances stability and improves load-bearing capacity. The reinforcing rib groups of the upper and lower plate assemblies and the reinforcing columns filled with steel pipes inside greatly improve the bending and compressive resistance capabilities, can carry heavy goods, reduce the risk of tray damage and cargo loss, and solve the problem of insufficient mechanical properties of traditional trays.

[0016] An anti-slip device is arranged in the installation groove, and the anti-slip device is composed of an anti-slip pad made of polyphenylene ether material and a base made of polypropylene material. While improving the anti-slip effect, the harder base can also prevent the accident of falling off caused by the softer anti-slip pad, providing strong support, thereby ensuring the stability of the goods during transportation, storage, and handling, and solving the anti-slip performance defect of the existing tray.

[0018] Hereinafter, with reference to the accompanying drawings, the anti-bending, anti-compression, anti-slip and high-load cross-shaped plastic logistics tray of the present invention will be specifically described.

[0019] As Figure 1 、 Figure 2 、 Figure 3 shown, the anti-bending, anti-compression, anti-slip and high-load cross-shaped plastic logistics tray includes an upper plate assembly 1 and a lower plate assembly 2. The upper plate assembly 1 is composed of a tray 11 and nine support foot columns 3, and the lower plate assembly 2 is composed of a bottom plate 21 and nine support foot columns 3. A support plate 22 is integrally provided at the edge of the bottom plate 21 between two adjacent support foot columns 3. First reinforcing rib groups 4 are uniformly provided inside the tray 11 and the bottom plate 21. Second reinforcing rib groups 5 are provided inside each support foot column 3. Reinforcing columns 6 are provided inside the tray 11 and the bottom plate 21. Steel pipes 61 are provided inside the reinforcing columns 6. Mounting holes 7 are respectively provided on the sides of the upper plate assembly 1 and the lower plate assembly 2. A weight-reducing hole 23 is provided on the bottom surface of the bottom plate 21. Third reinforcing rib groups 24 are provided on the bottom surface of the support plate 22. Mounting grooves 8 are uniformly provided at the top, inside of the tray 11 and the bottom of the bottom plate 21. Anti-slip devices 9 are provided in the mounting grooves 8.

[0020] Furthermore, the upper plate assembly 1 and the lower plate assembly 2 are connected by hot melting. Connecting the upper plate assembly 1 and the lower plate assembly 2 by hot melting can cause the materials of the two to melt and fuse into one under the action of high temperature. This connection method can form a connection part with high strength and good continuity, and its functions and effects are remarkable. On the one hand, it greatly enhances the stability of the overall structure of the tray, ensuring that there is no loosening or separation between the upper and lower plates during the process of carrying heavy objects and frequent handling, providing a solid guarantee for the bending and compressive resistance performance of the tray; on the other hand, compared with other connection methods such as bolt connection, hot melt connection does not require additional connecting parts, avoiding potential safety hazards caused by loosening and corrosion of the connecting parts, and the surface of the connection part is flat, reducing the risk of cargo scratching. At the same time, it simplifies the production process, improves production efficiency, and reduces production costs.

[0021] As Figure 3 , Figure 5 shown, the lower plate assembly 2 has a cross-shaped structure. The side surface of the support plate 22 has a certain inclination angle. A weight reduction groove 25 is provided on the bottom surface of the support plate 22, and a third reinforcing rib group 24 is arranged in the weight reduction groove 25. The third reinforcing rib group 24 is triangular. The lower plate assembly 2 adopts a cross-shaped structure and is matched with the support plate 22 with a specific design, and the effect is remarkable in improving performance and optimizing the structure. The cross-shaped structure enables the lower plate assembly 2 to have uniform load-bearing capacity in all directions, effectively disperses the weight of the goods, and enhances the overall stability. The side surface of the support plate 22 has a certain inclination angle, which can not only guide during handling to reduce collisions, but also facilitate forklift operation. The weight reduction groove 25 provided on the bottom surface of the support plate 22 reduces the overall weight of the tray on the premise of ensuring the structural strength, reducing transportation energy consumption and labor costs. The triangular third reinforcing rib group 24 in the weight reduction groove 25 utilizes the stability of the triangle to strengthen the compressive and bending resistance of the support plate 22, ensuring that it does not deform or damage when carrying heavy objects, and guaranteeing the reliable use of the tray in a complex logistics environment.

[0022] As Figure 4 , Figure 5 shown, the reinforcing ribs of the first reinforcing rib group 4 and the second reinforcing rib group 5 are arranged in a crisscross pattern. The first reinforcing rib group 4 and the second reinforcing rib group 5 are connected to the upper plate assembly 1 and the lower plate assembly 2 by integral injection molding. The first and second reinforcing rib groups are arranged in a crisscross pattern and are connected to the upper and lower plate assemblies by integral injection molding, playing a crucial role. The crisscross layout enhances the structural strength of the tray in all directions. Just like building a solid mechanical support network, it effectively improves the bending and anti-twisting capabilities of the upper and lower plate assemblies, ensuring that the tray surface is not easily deformed when carrying various goods. The integral injection molding connection method makes the reinforcing ribs and the plate assembly form a tight whole, eliminating the gaps and weak points that may be generated by traditional connection methods, and greatly enhancing the bonding strength.

[0023] Furthermore, the reinforcing column 6 is hollow. The reinforcing columns 6 in the tray 11 and the bottom plate 21 are arranged crosswise with each other. The reinforcing columns 6 in the tray 11 are horizontal, and the reinforcing columns 6 in the bottom plate 21 are vertical. The hollow reinforcing column 6 reduces its own weight while not reducing its structural strength, achieving a balance between lightweight and high strength. The reinforcing columns 6 in the tray 11 and the bottom plate 21 are arranged crosswise with different directions, constructing a three-dimensional support network that can disperse and bear external forces from multiple dimensions, effectively improving the overall bending resistance of the tray. When the tray faces complex stress conditions, it can still maintain structural stability and reduce the risk of deformation.

[0024] Such as Figure 4 , Figure 5 , Figure 7 , the number and positions of the mounting holes 7 match those of the reinforcing columns 6, and a plug 71 is provided in each mounting hole 7. The precisely matched mounting holes 7 provide precise positioning for the installation of the reinforcing columns 6, ensuring that the reinforcing columns 6 are installed firmly and in accurate positions, guaranteeing that they can fully play the role of enhancing the overall structural strength of the tray. The plug 71 can also prevent the steel pipe 61 inside the reinforcing column 6 from shifting or coming out, ensuring the stability and reliability of the connection between the reinforcing column 6 and the tray structure, and thus improving the safety and durability of the entire tray during logistics operations.

[0025] Such as Figure 7 , Figure 8 As shown, jack holes 61 are respectively provided at both ends of the reinforcing column 6 and on the plug 71, and a pin 62 is provided in the jack hole 61. After the pin 62 is inserted into the jack hole 61, the plug 71 and the reinforcing column 6 are tightly connected into a whole, greatly enhancing the reliability of the fixation of the plug 71, further preventing the accidental detachment of the plug 71, and avoiding the displacement of the steel pipe 61 inside the reinforcing column 6. Moreover, the connection method of the pin 62 provides convenience for subsequent maintenance, repair, or component replacement.

[0026] Furthermore, the plug 71 is divided into two types. One type has a wider shape and is used for the upper plate assembly 1, and the other type has a slender shape and is used for the lower plate assembly 2.

[0027] Furthermore, the front end of the pin 62 is a conical plug, and the end of the pin 62 is flat. The diameter of the conical plug at the front end is slightly larger than that of the jack hole 61. When inserted into the jack hole 61, it can gradually expand the surrounding material of the jack hole 61 by virtue of its taper to form an inverted buckle structure, and the flat design at the end enables the operator to apply force more conveniently when inserting and removing the pin 62, making the operation easier.

[0028] Such as Figure 9As shown, the anti-slip device 9 includes an anti-slip pad 91 and a base 92. The anti-slip pad 91 is made of polyphenylene ether, and the base 92 is made of polypropylene. The thickness of the anti-slip device 9 is higher than the depth of the installation groove 8. The anti-slip pad 91 made of polyphenylene ether has outstanding insulation performance, water resistance, high mechanical strength and a large surface friction coefficient, which can provide good anti-slip effect for the goods in various environments. The base 92 made of polypropylene has good rigidity, chemical corrosion resistance and molding processing performance, providing stable and reliable support for the anti-slip pad 91. The thickness of the anti-slip device 9 being higher than the depth of the installation groove 8 enables the anti-slip pad 91 to fully contact the goods, further increasing the friction force and improving the anti-slip effect.

[0029] As Figure 10 shown, the side of the support foot column 3 is provided with a protrusion 31, and the top surface of the tray 11 is provided with a convex pattern 12. The protrusion 31 on the side of the support foot column 3 can act as an anti-collision buffer structure during the handling of the tray, reducing the damage to the support foot column 3 caused by collision, effectively protecting the integrity of the tray structure and extending its service life. When the goods are shrink-wrapped, these protrusions 31 can be used as the support points for the shrink film, enabling the film to wrap the goods more tightly and stably, preventing the film from slipping, improving the packaging quality, while the convex pattern 12 on the top surface of the tray 11 greatly increases the friction force between the goods and the tray surface, effectively preventing the goods from sliding and displacing on the tray.

[0030] In this embodiment, the rectangular steel pipes 61 are respectively inserted into the interiors of the tray 11 and the bottom plate 21 from the installation holes 7, and the plugs 71 are installed in the installation holes 7. The pins 62 are inserted into the jacks 61 on the reinforcing columns 6 and the plugs 71 from the surfaces of the tray 11 and the bottom plate 21, and the plugs are passed through the reinforcing columns 6 for fixation. The base 92 of the anti-slip device 9 is driven into the installation groove 8 by an interference connection method. After installing the anti-slip device 9, the support foot columns 3 of the upper plate assembly 1 and the lower plate assembly 2 are aligned with each other and heat-melted and connected, so that the upper plate assembly 1 and the lower plate assembly 2 are fixed and connected together.

[0031] The above are only the preferred examples of the present application and are not used to limit the present application. For those skilled in the art, the present application can have other optimization schemes and additional functions. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
