Description

Technical Field

[0001] The utility model relates to the technical field of plastic runways, in particular to a runway material with high impact absorption. Background Art

[0002] Plastic tracks are widely used because of their good flatness, high compressive strength, appropriate hardness and elasticity, and stable physical properties. They are conducive to the athletes' speed and technology, effectively improving sports performance and reducing the rate of falls.

[0003] The existing technology has the following deficiencies: the prior art application number 201620536780.6 states that “a plastic running track” comprises a base surface layer, a primer layer composed of glue is provided on the base surface layer, a black granule layer composed of glue and black granules is provided on the primer layer, a sprayed surface layer composed of EPDM rubber particles is provided on the black granule layer, a heat insulation layer is provided between the black granule layer and the sprayed surface layer, the heat insulation layer is composed of aerogel felt material, and a water retention layer is provided between the heat insulation layer and the black granule layer, the water retention layer is formed by a mixture of sintered soil and glue”;

[0004] The above-mentioned equipment sets up insulation layers, breathable layers, etc., so that the runway is not easy to retain temperature, so as to quickly dissipate heat and improve the cooling effect of people walking. However, the above-mentioned equipment usually only sets up a single layer of cushioning pad as a cushioning layer to make the runway as a whole have a cushioning effect. The cushioning effect of the runway on impact force is relatively simple, and the runway surface layer is often easily worn and damaged. The wear resistance of the runway surface layer can be further improved. The buffer layer and surface layer of the above-mentioned equipment are usually designed as an integrated whole. During the use of the runway, the buffer layer and surface layer on the top will often be worn by force. When a part of the top of the runway is damaged after a long period of use, it usually needs to be replaced on a large scale. It is often difficult to replace it in a targeted manner, which easily leads to waste of resources. Utility Model Content

[0007] The buffer component includes a cavity, a first elastic block, a second elastic block and a filling particle block. The buffer layer is provided with a cavity, and the first elastic block, the second elastic block and the filling particle block are arranged in the cavity.

The first elastic block and the second elastic block are both semicircular as a whole and are made of soft rubber. Several groups of first elastic blocks and second elastic blocks are symmetrically arranged in the cavity, and the protruding ends of each group of first elastic blocks and the corresponding second elastic blocks are in contact with each other.

[0012] As an optimal technical solution of the present invention, the gaps between the first elastic block, the second elastic block and the cavity are filled with filling particle blocks, and the specific material of the filling particle blocks is EPDM particles.

[0015] 1. This runway material with high impact absorption is provided with a buffer component, a wear-resistant pad, a wear-resistant block, and a wear-resistant coating.

The runway material can buffer and absorb high impact forces. Since the wear-resistant pad itself has a certain wear resistance, the wear-resistant block can increase the coverage of the wear-resistant coating, thereby improving the overall wear resistance of the wear-resistant pad, and further improving the wear resistance of the top of the surface layer;

During this process, the corresponding fasteners are squeezed and deformed to fit tightly against the connecting block, and the connecting block will not move at will. The buffer layer module installed with the surface layer is relatively convenient to replace.

[0026] In this embodiment, the surface layer 3 is fixedly installed on the bottom of the buffer layer 2, and the specific material of the buffer layer 2 is silicone-modified polyurethane resin;

[0027] Specifically, the buffer layer 2 itself has a certain buffering effect;

[0028] In this embodiment, the wear-resistant pad 9 is fixedly mounted on the top of the surface layer 3 and is thin as a whole. The wear-resistant pad 9 and the plurality of groups of wear-resistant blocks 10 on the top form a whole. The specific material of the wear-resistant pad 9 is soft rubber.

[0029] Specifically, the wear-resistant pad 9 itself has good wear resistance;

[0031] Specifically, the wear-resistant block 10 can increase the contact range between the surface of the wear-resistant pad 9 and the wear-resistant coating 11, thereby increasing the coverage of the wear-resistant coating 11 and improving the overall wear resistance of the wear-resistant pad 9;

[0032] In this embodiment, the first elastic block 802 and the second elastic block 803 are fixedly mounted on the bottom and top of the inner wall of the cavity 801, respectively.

Since the first elastic block 802 and the second elastic block 803 are semicircular as a whole and the protruding ends of each group of first elastic blocks 802 and the corresponding second elastic blocks 803 are in contact with each other, the first elastic block 802 and the corresponding second elastic block 803 can offset each other's impact forces, and the filling particle block 804 can ensure the elasticity of the gap in the cavity 801, thereby improving the overall buffering effect of the buffer layer 2, and the runway material can buffer and absorb the high impact force received.

In this process, the corresponding fasteners 7 are squeezed and deformed and will fit tightly against the connecting block 5, and the connecting block 5 will not move at will. The connecting block 5 is clamped in the connecting groove 6 to limit the buffer layer 2 and surface layer 3 above the base layer 1 as a whole, and prevent the surface layer 3 and buffer layer 2 from moving left and right after being subjected to force. The replacement of the buffer layer 2 module with the surface layer 3 is relatively convenient. This structure can carry out targeted replacement of the damaged part of the runway top without large-scale overall replacement, which can reduce resource waste.
