Description

Technical Field

[0001] The utility model relates to the field of shoe soles, in particular to a non-slip and wear-resistant EVA sheet for shoe soles. Background Technique

[0002] EVA material is a copolymer, which is widely used in the preparation of shoe soles; the shoe soles directly made of EVA material have the properties of lightness, softness and non-slip and wear resistance during movement.

[0003] Traditional EVA sheets are similar to a non-slip EVA sheet disclosed in ZL202223143247.8. It improves the non-slip performance of the EVA sheet by setting non-slip strips on the bottom surface and making the non-slip strips arranged in a continuously bent shape. When this type of EVA sheet is applied to the preparation of shoe soles, the non-slip strip, as the main structure in contact with the ground, has poor wear resistance itself; and the non-slip performance of the non-slip strip is limited when stressed on the left and right sides. When the user is moving, the shoe sole is easily subjected to forces in various directions, especially the forces on the left and right sides. This structure cannot meet the non-slip requirements of the shoe sole during movement.

[0004] Therefore, the existing EVA shoe soles have problems of poor wear resistance and poor non-slip performance. Content of the Utility Model

[0005] The purpose of the utility model is to provide a non-slip and wear-resistant EVA sheet for shoe soles. The utility model can not only improve the wear resistance, but also has the advantage of good non-slip performance.

[0006] The technical solution of the utility model: A non-slip and wear-resistant EVA sheet for shoe soles, including an EVA layer; a plurality of anti-slip protrusions are provided on the bottom surface of the EVA layer. The top of each anti-slip protrusion located on the left side of the front end and the right side of the rear end of the bottom surface of the EVA layer is provided with a first anti-slip concave groove inclined to the left, and the top of each anti-slip protrusion located on the right side of the front end and the left side of the rear end of the bottom surface of the EVA layer is provided with a second anti-slip concave groove inclined to the right; a first sponge layer, a deodorizing layer, a second sponge layer and a breathable mesh layer are adhesively connected in sequence above the EVA layer, and a plurality of air holes distributed in an array are provided on the second sponge layer.

[0007] In the foregoing non-slip and wear-resistant EVA sheet for shoe soles, grooves are provided at the front end and the rear end of the bottom surface of the EVA layer, and an anti-slip rubber sheet is adhesively bonded to each groove, and a plurality of transverse anti-slip concave grooves are provided on the surface of each anti-slip rubber sheet.

[0008] In the foregoing non-slip and wear-resistant EVA sheet for shoe soles, an anti-slip rubber strip is arranged in the anti-slip concave groove, and the top end of the anti-slip rubber strip is lower than the top end of the anti-slip concave groove.

[0009] In the aforementioned anti-skid and wear-resistant EVA sheet for shoe soles, the distance between the top of the anti-skid rubber strip and the top of the anti-skid groove is 1 mm.

[0010] In the aforementioned anti-skid and wear-resistant EVA sheet for shoe soles, the anti-skid protrusions are in the shape of prisms.

[0011] In the aforementioned anti-skid and wear-resistant EVA sheet for shoe soles, the height of the anti-skid protrusions is 3 mm, and the spacing between adjacent anti-skid protrusions is 5 mm.

[0012] Compared with the prior art, the utility model improves the anti-skid performance by providing a plurality of anti-skid protrusions on the left side of the front end, the right side of the front end, the left side of the rear end and the right side of the rear end at the bottom surface of the EVA layer, and the anti-skid protrusions are made of EVA and have good wear resistance; the top surface of each anti-skid protrusion at the left side of the front end and the right side of the rear end is provided with a first anti-skid groove inclined to the left, and the top surface of each anti-skid protrusion at the right side of the front end and the left side of the rear end is provided with a second anti-skid groove inclined to the right, so that each anti-skid protrusion has good anti-skid performance, and the bottom surface of the entire EVA layer can form a diamond-shaped anti-skid pattern, which can better meet the anti-skid requirements when subjected to force in all directions, and has good anti-skid performance. By sequentially adhering the first sponge layer, the deodorizing layer, the second sponge layer and the breathable mesh layer on the top of the EVA layer, it has a comfortable stepping feeling and deodorizing effect; by providing a plurality of air holes distributed in an array on the second sponge layer, the gas at the sole of the foot can more conveniently penetrate into the deodorizing layer when stepping, improving the deodorizing effect.

[0013] In addition, the front and rear ends of the bottom surface of the EVA layer in the utility model are provided with grooves, and anti-skid rubber sheets are connected in the grooves, and each anti-skid rubber sheet is provided with a plurality of transverse anti-skid grooves, which improves the anti-skid performance of the front and rear ends of the EVA layer when running and stopping; and the anti-skid rubber sheet is made of rubber, which has good wear resistance. An anti-skid rubber strip is provided in each anti-skid groove, and a 1mm gap is provided between the top of the anti-skid rubber strip and the top of the anti-skid groove, which ensures that the surface of the anti-skid rubber sheet remains concave and convex while avoiding granular stones from getting stuck in the anti-skid grooves, and when running on the plastic track, the concave and convex particles on the plastic track can contact the anti-skid rubber strip, further improving the anti-skid performance.

[0014] The anti-skid protrusions are in the shape of prisms, and the height of the anti-skid protrusions is 3 mm, and the spacing between adjacent anti-skid protrusions is 5 mm, so that granular stones on the road surface are not easily stuck between adjacent anti-skid protrusions.

[0015] Therefore, the utility model can not only improve the wear resistance, but also has the advantages of good anti-skid performance, good deodorizing effect and not easy to get stuck with stones. BRIEF DESCRIPTION OF THE DRAWINGS
