[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Please refer to the attached Figure 1-5 The utility model provides a composite plastic track that can be quickly assembled, including several bottom substrates 1, each of which is provided with a surface layer 2 on the top, and each of which is provided with an anti-slip layer 3 on the top of the surface layer 2, that is, a composite plastic track is realized, and two adjacent bottom substrates 1 are fixedly connected by a splicing assembly;

[0024] The surface layer 2 is set to be PU injection molding material. The surface layer 2 is sprayed on the top of the bottom substrate 1. The surface layer 2 is set to 5-8mm. The surface layer 2 of PU injection molding material has good elasticity and good aging resistance, which is conducive to extending the service life of the plastic track.

[0025] The anti-slip layer 3 is made of EPDM particles and is sprayed on top of the surface layer 2. The thickness of the anti-slip layer 3 is 3-5 mm. EPDM particles are a polymer material made from ethylene propylene diene monomers. They have excellent weather resistance, aging resistance, and chemical resistance, and have good elasticity and shock absorption. They can effectively reduce the stress on athletes and children during exercise and reduce sports injuries. EPDM particles are also anti-slip, wear-resistant, waterproof, and easy to clean.

[0026] The splicing assembly includes a connecting slide rail 4, which is arranged at one end of the bottom substrate 1, and the connecting slide rail 4 and the bottom substrate 1 are an integrated structure to ensure the structural strength between the bottom substrate 1 and the connecting slide rail 4. A connecting slide groove 5 is provided at the other end of the bottom substrate 1, and a slope 6 is provided at the notches at both ends of the connecting slide groove 5. A mounting hole 7 is provided in the middle of the connecting slide rail 4, and a partition 8 is fixed in the middle of the mounting hole 7. Reset springs 9 are symmetrically fixed to the upper and lower ends of the partition 8. A limit plate 10 is fixed to the end of the reset spring 9 away from the partition 8, and a positioning pin 11 is fixed to the end of the limit plate 10 away from the reset spring 9. End covers 12 are fixed to the upper and lower ends of the mounting hole 7. A limiting hole 13 is provided in the center of the end covers 12. The end of the positioning pin 11 away from the limiting piece 10 passes through the limiting hole 13. Specifically, under the joint action of the limiting piece 10 and the end cover 12, the positioning pin 11 can be prevented from being separated from the mounting hole 7. When the user slides the connecting slide rail 4 into the connecting slide groove 5 provided on the side end of the adjacent bottom substrate 1, the positioning pin 11 will first pass through the inclined surface 6. Then, as the user continues to slide in, the positioning pin 11 will be squeezed and retracted into the mounting hole 7, thereby compressing the return spring 9, causing the return spring 9 to undergo elastic deformation and generate elastic force.

[0027] When the connecting rail 4 slides into the connecting rail 5 opened at the side end of the adjacent bottom substrate 1, the positioning pin 11 is inserted into the corresponding positioning slot 14. Specifically, as the connecting rail 4 continues to slide into the connecting rail 5, when the positioning pin 11 is squeezed and contracted into the mounting hole 7, it moves to the corresponding positioning slot 14. At this time, the positioning pin 11 is no longer squeezed by the inner wall of the connecting rail 5. Under the elastic force generated by the elastic deformation of the return spring 9, the positioning pin 11 is automatically pushed out, so that it can be inserted into the corresponding positioning slot 14, so that the two adjacent bottom substrates 1 can achieve the function of quick assembly, that is, the function of quick assembly of the composite plastic runway is realized. The operation is simple and convenient, and before assembly, several bottom substrates 1 can be conveniently carried and transported.

[0028] The use process of the present invention is as follows: when assembling, the user can first transport several pieces of bottom base plates 1 to the site where they need to be assembled, and then slide the connecting slide rail 4 at one end of the bottom base plate 1 into the connecting slide groove 5 opened at the side end of the adjacent bottom base plate 1. When the user slides the connecting slide rail 4 into the connecting slide groove 5 opened at the side end of the adjacent bottom base plate 1, the positioning pin 11 will first pass through the inclined surface 6, and then as it continues to slide in, the positioning pin 11 will be squeezed and contracted into the mounting hole 7, thereby compressing the reset spring 9, causing the reset spring 9 to undergo elastic deformation and generate elastic force, and then as the connecting slide The rail 4 continues to slide into the connecting slide 5. When the positioning pin 11 is squeezed and retracted into the mounting hole 7, it moves to the corresponding positioning slot 14. At this time, the positioning pin 11 is no longer squeezed by the inner wall of the connecting slide 5. Under the elastic force generated by the elastic deformation of the return spring 9, the positioning pin 11 is automatically pushed out and can be inserted into the corresponding positioning slot 14, so that the two adjacent bottom substrates 1 can be quickly assembled, that is, the composite plastic runway can be quickly assembled. The operation is simple and convenient, and before assembly, several bottom substrates 1 can be easily carried and transported.

[0029] During use, under the action of the surface layer 2 made of PU injection molding material, it has better elasticity and good aging resistance, which is conducive to extending the service life of the plastic track. Under the action of the anti-slip layer 3 made of EPDM granular material, it has excellent weather resistance, aging resistance and chemical resistance, and has good elasticity and shock absorption, which can effectively reduce the force exerted on athletes and children during exercise and reduce sports injuries. It also has the characteristics of anti-slip, wear resistance, waterproof and easy to clean.

Anyone skilled in the art can utilize the above-described technical solutions to modify the present invention or create equivalent technical solutions. Therefore, any simple modification or equivalent replacement based on the technical solutions of the present invention falls within the scope of protection claimed by the present invention.
