Description

Technical Field

[0001] This utility model relates to the field of prefabricated plastic running track technology, specifically an environmentally friendly prefabricated plastic running track. Background Technology

[0002] Precast synthetic running tracks are a type of prefabricated sports surface system with a flat structure. They consist of a friction surface layer, a shock-absorbing base layer, and an adhesive layer. During installation, adhesive is first evenly applied to the surface, and then the shock-absorbing base layer is bonded to the adhesive. After installation, people can run, walk, and exercise on the friction surface layer. Precast synthetic running tracks are made of environmentally friendly materials with natural and synthetic rubber as the main base materials, thus possessing environmentally friendly characteristics.

[0003] The inventors discovered in their daily work that when using prefabricated plastic running tracks, the friction surface is most easily damaged by friction due to people running, walking, and exercising on it. Since the friction surface and the shock-absorbing bottom layer are connected by an integrated composite production process, replacing the friction surface layer also requires replacing the shock-absorbing bottom layer, which may lead to a waste of resources. Utility Model Content

[0004] To address the issue that the friction surface layer of prefabricated plastic running tracks is easily damaged during use, and that traditional prefabricated plastic running tracks can only be replaced as a whole, resulting in resource waste, this utility model provides an environmentally friendly prefabricated plastic running track.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0018] As a further description of the above technical solution:

[0019] The shock-absorbing bottom layer is square, and the shock-absorbing bottom layer is provided with plug-in structures in both the horizontal and vertical directions.

[0020] As a further description of the above technical solution:

[0021] The distance between the fins and the conical ring is not less than 2 cm.

[0022] As a further description of the above technical solution:

[0023] The cone, fins, conical ring, and column are integrated into one structure.

[0024] As a further description of the above technical solution:

[0025] The fastening structure is distributed in a rectangular array between the shock-absorbing bottom layer and the friction surface layer.

[0026] The beneficial effects of this utility model are:

[0037] Please refer to the attached document. Figure 1 - Figure 6 This application illustrates an environmentally friendly prefabricated plastic running track provided in an embodiment of the present application, used for laying prefabricated plastic running tracks, which includes: a shock-absorbing base layer 1 and a friction surface layer 2 installed on top of the shock-absorbing base layer 1 through a fastening structure 3.

[0038] In this embodiment, the shock-absorbing base layer 1 and the friction surface layer 2 of the prefabricated plastic running track are separated and installed together using a snap-fit ​​structure 3. In actual use, when the friction surface layer 2 is damaged, the workers can remove the damaged friction surface layer and replace it with a new one, thus extending the overall service life of the prefabricated plastic running track without wasting the shock-absorbing base layer 1. Moreover, the process of replacing only the friction surface layer is simple, with higher construction efficiency, and it can be used immediately without the need for construction barriers.

[0039] Specifically, the fastening structure 3 includes: an inlet 302 opened on the top surface of the shock-absorbing bottom layer 1 and a plug 301 fixedly connected to the bottom of the friction surface layer 2. A base 3021 is fixedly provided on the inner bottom of the inlet 302, and a metal ring 3022 is fixedly connected to the top of the base 3021. Multiple limiting blocks 3023 are provided on the inner side of the metal ring 3022. The metal ring 3022 and the limiting blocks 3023 are made of metal and have sufficient strength to maintain structural stability during repeated disassembly, installation and use. The plug 301 includes, from bottom to top: a cone head 3012, a fin 3013, a conical ring 3014, and a column 3011.

[0040] During installation, the cone head 3012 acts as a guide. The fin 3013 first contacts the limiting block 3023 inside the metal ring 3022. Then, the installer uses a rubber hammer to tap and rub the surface layer 2, causing the fin 3013 to break. The plug 301 moves downward quickly, and the conical ring 3014 moves downward quickly, deforming past the limiting block 3023 inside the metal ring 3022. After that, the limiting block 3023 gets stuck on the top of the conical ring 3014, completing the installation of the fastening structure 3. The connection is very stable after installation. When disassembling, a screwdriver is needed to pry out the plug 301, causing the conical ring 3014 to be damaged and deformed.

[0041] In one embodiment, a friction surface 2a is provided on the top of the friction surface layer 2, and the friction surface 2a serves as an anti-slip surface.

[0042] In one embodiment, multiple shock-absorbing substrates 1 are provided, and an interlocking structure is provided between two adjacent shock-absorbing substrates 1. In this way, multiple shock-absorbing substrates 1 can be spliced ​​into various shapes to adapt to different ground needs.

[0043] In one embodiment, the plug-in structure includes: a T-shaped female connector 101 and a plug-in male connector 102. The plug-in male connector 102 includes: a main body 1021, and both ends of the main body 1021 are fixedly provided with buckle members 1022, which are snapped into the recesses on the side of the T-shaped female connector 101.

[0044] In one embodiment, the shock-absorbing bottom layer 1 is square, and the shock-absorbing bottom layer 1 is provided with plug-in structures in both the horizontal and vertical directions, so that the shock-absorbing bottom layer 1 can be spliced ​​in both the horizontal and vertical directions.

[0045] In one embodiment, the gap between the fin 3013 and the conical ring 3014 is not less than 2 cm, ensuring that the limiting block 3023 has an acceleration process after passing the fin 3013, and ensuring that the limiting block 302 can quickly pass the conical ring 3014 (the conical ring 3014 is made of plastic, which can be deformed or damaged under a large force).

[0046] In one embodiment, the cone head 3012, fin 3013, conical ring 3014, and column 3011 are an integral structure, which can be integrally formed by injection molding.

[0047] In one embodiment, the fastening structure 3 is distributed in a rectangular array between the shock-absorbing bottom layer 1 and the friction surface layer 2.
