DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-5A wear-resistant and high-temperature resistant plastic pallet comprises a pallet body 1, characterized in that the pallet body 1 is provided with a through hole, in which two air-permeable plates 4 are fixedly installed, and the two air-permeable plates 4 are provided with a plurality of air-permeable holes, and three groups of wear-resistant layers 5 are arranged on the top side of the upper air-permeable plate 4, and the number of each group of wear-resistant layers 5 is multiple, and the material of each wear-resistant layer 5 is nitrile rubber, and multiple support seats 2 are arranged below the pallet body 1, and the bottom sides of the multiple support seats 2 are provided with slots, and the multiple slots are plugged with wear-resistant pads 3, and the material of the multiple wear-resistant pads 3 is wear-resistant steel, and clamping limiters are arranged between the multiple support seats 2. The component comprises a tray body 1 and a breathable plate 4, wherein the materials of the tray body 1 and the breathable plate 4 are polyimide and polyether ketone respectively, and polyimide has good high temperature durability and mechanical properties, can be used at a temperature of up to 350°C, and has excellent chemical stability and electrical properties, and polyether ketone material has good stability and mechanical properties in high temperature and chemical corrosion environments, and can also be used at a temperature of up to 250°C, and polyether ketone material has excellent friction and wear properties, and can withstand a certain degree of high temperature resistance, and by setting multiple wear-resistant layers 5, multiple wear-resistant layers 5 The materials are all nitrile rubber, which is a synthetic rubber with excellent oil resistance, solvent resistance, chemical resistance and wear resistance. Among various synthetic rubbers, nitrile rubber has higher mechanical strength and can maintain softness without deformation. Because there are multiple wear-resistant layers 5, after the wear-resistant layer 5 on the top side is damaged, you only need to tear off the wear-resistant layer 5 on the top side, and then the new wear-resistant layer 5 can be used for a long time, thereby greatly increasing the overall service life of the pallet body 1. And because the two breathable plates 4 are provided with multiple breathable holes, they can During forklift transportation, outside air can enter the bottom of the cargo through multiple air holes, thereby having a heat dissipation effect on the cargo, and at the same time, the two air permeable plates 4 can also dissipate heat. In addition, multiple wear-resistant pads 3 are provided, and the material of the multiple wear-resistant pads 3 is wear-resistant steel. Wear-resistant steel is a material that performs well when subjected to impact and friction. When subjected to impact or contact stress, its surface will harden rapidly, while the core maintains high toughness. This hard-outer-tough-inner characteristic makes it both wear-resistant and impact-resistant. Therefore, when the forklift places the pallet body 1 on the ground, the multiple wear-resistant pads 3 can play a wear-resistant role.

[0023] Specifically, the clamping limit assembly includes two support seats 2, both of which are provided with circular holes, and a bidirectional screw 6 is arranged in the circular holes, one end of the bidirectional screw 6 is rotatably connected to one side of the support seat 2 on the left side, and two groups of first thread grooves 7 and second thread grooves 8 are respectively provided on the outer sides of the bidirectional screw 6, and the thread directions of the two groups of first thread grooves 7 and second thread grooves 8 are opposite, and the outer sides of the two first thread grooves 7 and the two second thread grooves 8 are respectively slidably installed with a first slider 10 and a second slider 11, and the two groups of first sliders 10 and the second sliders 11 are symmetrically arranged, and the top sides of the two groups of first sliders 10 and the two groups of second sliders 11 are respectively fixedly installed with a second clamping plate 18 and a first clamping plate 12, and the two groups of first clamping plates 12 and the second clamping plates 18 are both Z-shaped, and the two groups of first clamping plates 12 and the two groups of second clamping plates 18 are symmetrically arranged, and the other end of the bidirectional screw 6 is fixedly connected with a rotating disk 13, and a plurality of rotating rods 14 are fixedly installed on the outer side of the rotating disk 13, and the plurality of rotating rods 14 are distributed in a circular array, and the rotating disk 13 and the support seat 2 on the right side are respectively provided with a plurality of The mounting holes 15 and the plurality of mounting grooves 16, one of the mounting holes 15 among the plurality of mounting holes 15 is internally threadedly installed with a threaded column 17, and the other end of the threaded column 17 is threadedly installed in the mounting groove 16 aligned with one of the mounting holes 15. When the forklift inserts the two insertion rods between the three support seats 2, the bidirectional screw 6 is rotated synchronously by rotating the turntable 13 clockwise, so that the two groups of first sliders 10 and the two groups of second sliders 11 are close to each other, and then the two groups of first clamping plates 12 and the two groups of second clamping plates 18 are close to each other toward the two sides of the two insertion rods, and then the clamping and limiting of the two insertion rods are completed, so that in the process of transporting goods by the forklift, the two insertion rods can be fixed by the two groups of first clamping plates 12 and the two groups of second clamping plates 18, thereby preventing the pallet body 1 from being separated from the insertion rod, causing the goods to fall off. When separation is required, the turntable 13 only needs to be rotated counterclockwise to make the two groups of first sliders 10 and the two groups of second sliders 11 move away from each other, so that the first clamping plates 12 and the second clamping plates 18 stop clamping the two insertion rods.

[0024] Specifically, a support seat 2 located in the middle is provided with two circular holes, and guide rods 9 are fixedly installed in the two circular holes. Two groups of first sliders 10 and two groups of second sliders 11 slide on the two guide rods 9 respectively. The two guide rods 9 can provide a stable guiding effect when the two groups of first sliders 10 and the two groups of second sliders 11 move away from each other or move away from each other.

[0025] When in use: by setting the tray body 1 and the breathable plate 4, and the materials of the tray body 1 and the breathable plate 4 are polyimide and polyether ketone respectively, and polyimide has good high temperature durability and mechanical properties, can be used at a temperature of up to 350°C, and has excellent chemical stability and electrical properties, and the polyether ketone material has good stability and mechanical properties in high temperature and chemical corrosion environment, and can also be used at a temperature of up to 250°C, and the polyether ketone material has excellent friction and wear properties, and can withstand a certain degree of high temperature resistance, and by setting multiple wear-resistant layers 5, the material of the multiple wear-resistant layers 5 is nitrile rubber, and nitrile rubber is a synthetic rubber with excellent oil resistance, solvent resistance, chemical resistance and wear resistance. Among various synthetic rubbers, nitrile rubber has higher mechanical strength, and can maintain softness without deformation, and because there are multiple wear-resistant layers 5, the wear-resistant layer 5 located on the top side is When the forklift 10 is used to transport the goods, the two rods can be fixed by the two groups of first and second clamping plates 12 and 18, thereby preventing the pallet body 1 from being separated from the rods and causing the goods to fall off. When separation is required, the turntable 13 can be rotated counterclockwise to make the two groups of first and second sliders 10 and 11 move away from each other, thereby stopping the first and second clamping plates 12 and 18 from clamping the two rods.
