It is one of the essential logistics equipment in modern logistics warehousing. Generally, plastic pallets made of polyethylene have good wear resistance, strong impact resistance, light weight, long service life, and good corrosion resistance due to the presence of organic solvents. However, the mechanical properties of plastic pallets are generally average, with low tensile strength, poor creep resistance, and being greatly affected by the environment. For example, they are prone to brittleness and fracture in arid and low-temperature weather environments.

The bottom of the bottom layer is provided with several support columns. The intermediate reinforcement layer includes a grid plate and an outer reinforcement strip. The outer reinforcement strip is arranged around the side wall of the grid plate. The upper and lower parts of the grid plate are respectively embedded in the first cavity and the second cavity, and the outer reinforcement strip is arranged between the top layer and the bottom layer. By setting the intermediate reinforcement layer with a grid structure, the plastic pallet is divided into three-layer structure, increasing the anti-lateral extrusion ability of the plastic pallet. The outer reinforcement strip is fixedly connected to the top layer and the bottom layer to improve the overall structural strength of the plastic pallet.

[0004] The above technology divides the plastic pallet into three-layer structure, and the intermediate reinforcement layer is located in the middle, making it difficult to change the stress structure of the plastic pallet, with limited strengthening effect on the plastic pallet. Moreover, the intermediate reinforcement layer increases the load of the pallet. When handling light goods, it instead increases the load, resulting in poor flexibility in use. Therefore, the utility model discloses a high-strength plastic pallet to solve the above problems. Summary of the Utility Model

[0027] The following further describes the present utility model in conjunction with embodiments.

[0028] Please refer to Figures 1-6 , the present utility model provides a high-strength plastic pallet, including a plastic main board 1, a stainless steel skeleton 2 and a plastic pallet 3;

[0029] Specifically, the plastic main board 1 and the plastic pallet 3 are both made of plastic materials, with the advantages of good wear resistance, strong impact resistance, light weight, long service life, and good corrosion resistance due to the containing organic solvents. The stainless steel skeleton 2 is made of stainless steel metal material, which can overcome the general mechanical properties of plastic materials, low tensile strength, poor creep resistance, and being greatly affected by the environment. For example, it is easy to be brittle and break in arid and low-temperature weather environments. The two complement each other and improve the overall performance;

[0030] Further, a plurality of drainage grooves 14 are formed on the plastic main board 1;

[0031] Specifically, the drainage grooves 14 can effectively drain the water on the plastic main board 1 and keep the goods dry and clean, which is particularly important for storing and transporting goods vulnerable to moisture.

[0032] Further, a plurality of load-bearing leg supports 11 are arranged in an array on the lower side of the plastic main board 1, and 9 load-bearing leg supports 11 are provided;

[0033] Specifically, the load-bearing leg supports 11 play a role in dispersing the support. The forklift can fork up and transfer the plastic main board 1 and the goods on its upper side by using the gaps between the load-bearing leg supports 11.

[0034] Further, plastic pallets 3 are connected between the load-bearing leg supports 11 in the same row, and 3 plastic pallets 3 are provided;

[0035] Specifically, the plastic pallets 3 play a role in dispersing the force on the load-bearing leg supports 11, which is important for realizing the structural stability of the plastic pallets 3.

[0036] Furthermore, a recessed groove 31 is provided on the upper side of the plastic support plate 3 corresponding to the load-bearing leg support 11, a limiting groove 311 is provided in the middle of the recessed groove 31 corresponding to the load-bearing reinforcement tube 21, and a hidden groove 312 having the same width as the load-bearing foot plate 211 is provided on the lower side of the plastic support plate 3;

[0037] Specifically, the recessed groove 31 allows the load-bearing leg support 11 to be correctly positioned in the plastic pallet 3 to prevent it from being displaced during the use of the pallet. The limiting groove 311 exists to provide additional fixing effect to ensure that the connection between the load-bearing reinforcement tube 21 and the plastic pallet 3 is more secure, thereby improving the load-bearing capacity and structural strength of the entire pallet. A hidden groove 312 consistent with the width of the load-bearing foot plate 211 is provided on the lower side of the plastic pallet 3. This design allows the load-bearing foot plate 211 to be embedded in the hidden groove 312, thereby enhancing the connection strength between the load-bearing foot plate 211 and the plastic pallet 3 and providing better support and load dispersion capabilities.

[0038] Furthermore, a receiving groove 111 is provided on the upper side of the load-bearing leg support 11, a first slot 12 is provided between two opposite side walls of the plastic main board 1, and a second slot 13 is provided between the other two opposite side walls of the plastic main board 1, and the first slot 12, the second slot 13 and the receiving groove 111 are connected to each other;

[0039] Specifically, the first slot 12 and the second slot 13 can form a grid structure, which can play the role of limiting the transverse steel pipe 22 and the longitudinal steel pipe 23. It is worth noting that the height of the first slot 12 is greater than the height of the second slot 13, so that the longitudinal steel pipe 23 can pass through the transverse steel pipe 22.

[0040] Further, the stainless steel frame 2 is installed between the plastic main board 1 and the plurality of plastic support plates 3. The stainless steel frame 2 is composed of a load-bearing reinforcement tube 21, a transverse steel tube 22 and a longitudinal steel tube 23. The transverse steel tube 22 is arranged through the first slot 12. The portion of the transverse steel tube 22 located in the receiving groove 111 is sleeved with the load-bearing reinforcement tube 21. The bottom end of the load-bearing reinforcement tube 21 passes through the load-bearing leg support 11 and the plastic support plate 3 is fixed with a load-bearing foot plate 211. The longitudinal steel tube 23 is arranged through the second slot 13 and each transverse steel tube 22.

[0041] Specifically, when subjected to stress, the pressure exerted on the plastic main board 1 is partially transmitted to the load-bearing reinforcement tube 21 through the grid structure formed by the transverse steel tube 22 and the longitudinal steel tube 23. The load-bearing reinforcement tube 21 disperses the stress to the ground through the load-bearing foot plate 211, thereby greatly increasing the maximum load of the plastic pallet.

[0042] Further, a first fitting groove 212 is provided on the load-bearing and strengthening pipe 21 corresponding to the cross-sectional structure of the transverse steel pipe 22, and a plurality of second fitting grooves 221 are provided on the transverse steel pipe 22 corresponding to the cross-sectional structure of the longitudinal steel pipe 23;

[0043] Specifically, after the load-bearing and strengthening pipe 21 passes through the first fitting groove 212, it can prevent the load-bearing and strengthening pipe 21 from slipping out downward. After the longitudinal steel pipe 23 passes through the second fitting groove 221, it can prevent the transverse steel pipe 22 from moving back and forth, so that the load-bearing and strengthening pipe 21, the transverse steel pipe 22, and the longitudinal steel pipe 23 can form a three-dimensional support structure.

[0044] Further, sealing plugs 4 are press-fitted at both ends of the first insertion slot 12 and the second insertion slot 13, and the sealing plugs 4 are made of plastic materials;

[0045] Specifically, the sealing plugs 4 are tightly installed at both ends of the first insertion slot 12 and the second insertion slot 13 to ensure that the sealing plugs 4 will not loosen or fall off during the use of the tray, playing a role in limiting the transverse steel pipe 22 and the longitudinal steel pipe 23 to prevent the transverse steel pipe 22 and the longitudinal steel pipe 23 from slipping out. On the other hand, the sealing plugs 4 can seal the first insertion slot 12 and the second insertion slot 13 to prevent the transverse steel pipe 22 and the longitudinal steel pipe 23 from being rusted by humid air, with beautiful appearance and good integrity.

[0046] Working principle:

[0047] During use, the plastic main board 1 alone bears the goods, and the load-bearing leg supports 11 play a role in dispersing the support. The forklift can fork up and transfer the plastic main board 1 and the goods on its upper side by using the gap between the load-bearing leg supports 11. When carrying heavy objects, first pass the load-bearing and strengthening pipes 21 through the respective limit grooves 311, then pass the transverse steel pipes 22 through the respective first insertion slots 12, and then pass the longitudinal steel pipes 23 through the respective second insertion slots 13. Press-fit the sealing plugs 4 into the respective ports of the first insertion slot 12 and the second insertion slot 13, and the assembly and strengthening of the plastic tray structure can be completed. When stressed, part of the pressure received by the plastic main board 1 is transmitted to the load-bearing and strengthening pipe 21 by the grid-like structure formed by the transverse steel pipe 22 and the longitudinal steel pipe 23. The load-bearing and strengthening pipe 21 disperses the force to the ground through the load-bearing foot plate 211, greatly improving the maximum load of the plastic tray.
