Description

Technical Field

[0001] The utility model relates to a sole, in particular to a wear-resistant sole. Background Art

[0002] Shoes are a necessity of life, and their comfort, breathability, warmth retention, deodorization, skid resistance, and wear resistance are key features that people consider when choosing shoes. Skid resistance and wear resistance are essential features of a shoe sole, directly impacting wear safety. Outdoor shoes and military footwear, in particular, place high demands on the wear resistance of their soles. To enhance the wear resistance of their soles, high-wear-resistant rubber has been used in the overall soles. While this improves the wear-resistant hardness of the soles, it also makes the soles heavier and reduces comfort. Furthermore, existing wear-resistant soles focus solely on the wear resistance of the soles, lacking grip, making them unsuitable for use in unusual road conditions. Therefore, there is a need to design a wear-resistant sole that combines both grip and wear resistance. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide a wear-resistant sole, which has good wear resistance, grip and anti-slip properties, and is comfortable to wear.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a wear-resistant sole, comprising a sole body and a waist reinforcement part, wherein the waist reinforcement part is fixed at the waist of the bottom of the sole body, and a number of raised particles extending outward are evenly arranged on the outer surface of the waist reinforcement part.

[0005] Furthermore, the protruding particles are streamlined quadrangular prism protrusions.

[0006] Furthermore, a first reinforcement portion and a second reinforcement portion are press-fitted and fixed to the forefoot of the bottom of the sole body. The first reinforcement portion corresponds to the first metatarsophalangeal joint of the human foot, and the second reinforcement portion corresponds to the fifth metatarsophalangeal joint of the human foot.

[0007] Furthermore, a heel reinforcement portion is press-fitted and fixed to the heel of the sole body.

[0008] Furthermore, the hardness of the first reinforcement part, the second reinforcement part and the heel reinforcement part is greater than the hardness of the sole body.

[0009] Furthermore, the shoe waist reinforcement portion is pressed and fixed to the shoe waist of the bottom of the sole body, and the shoe waist reinforcement portion and the bottom of the sole body are hot-pressed.

[0010] Furthermore, the shoe waist reinforcement part is prepared by mixing modified carbon black and rubber.

[0011] Furthermore, outer surfaces of the first reinforcement portion, the second reinforcement portion and the heel reinforcement portion are flush with the raised outer surface of the sole body.

[0012] Furthermore, the heights of the first reinforcement portion, the second reinforcement portion and the heel reinforcement portion are greater than the protrusion of the sole body.

[0013] Furthermore, grooves are provided at the forefoot, heel and arch of the upper end of the sole body, shock-absorbing blocks are provided in the forefoot groove and the heel groove, and a carbon fiber plate is provided in the arch groove.

[0014] The effects of the utility model are as follows:

[0015] 1. A waist reinforcement part is fixed to the bottom of the sole body, and the waist reinforcement part has a number of evenly arranged streamlined quadrangular prism raised particles. The raised particles deform according to the structure of the waist pit, and the raised particles protrude outward, which is beneficial to increase grip, enhance anti-slip performance, and increase the aesthetics of the sole.

[0016] 2. The forefoot of the sole has a first reinforcement and a second reinforcement, corresponding to the first and fifth metatarsophalangeal joints of the human foot, and the heel has a heel reinforcement. The areas corresponding to the first, second, and heel reinforcements are prone to severe wear during walking. The material hardness of these three areas is greater than that of the sole body, enhancing the wear resistance of these three areas. Furthermore, the material of the sole body is softer than these three areas, making the overall weight of the sole body lighter. This ensures the sole's wear resistance while also ensuring comfortable wearing. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Reference Figure 1-3As shown, the utility model provides a wear-resistant sole, comprising a sole body 1 and a waist reinforcement part 2. The waist reinforcement part 2 is separately pressed together to form an independent accessory, and then hot-pressed with the bottom of the sole body so that the waist reinforcement part 2 is pressed and fixed at the waist of the bottom of the sole body. The waist reinforcement part 2 is prepared by mixing modified carbon black and rubber. The modified carbon black serves as a reinforcing filler for the rubber, which makes the waist reinforcement part have high wear resistance, high grip and torsion resistance. A number of raised particles 21 are evenly arranged on the outer surface of the waist reinforcement part, wherein the raised particles are streamlined quadrangular prism protrusions. The quadrangular prism raised particles are combined with the material of the waist reinforcement part to enhance the grip at the waist and improve the poor anti-slip situation.

[0022] Furthermore, a first reinforcement portion 3 and a second reinforcement portion 4 are press-fitted and fixed at the forefoot of the bottom of the sole body, and a heel reinforcement portion 5 is press-fitted and fixed at the heel of the sole body, wherein the first reinforcement portion, the second reinforcement portion and the heel reinforcement portion all have a plurality of wear-resistant protrusions. The sole body is preferably made of rubber material, and the first reinforcement portion 3, the second reinforcement portion 4 and the heel reinforcement portion 5 are made of highly wear-resistant rubber material, and the material hardness of the first reinforcement portion 3, the second reinforcement portion 4 and the heel reinforcement portion 5 is greater than the hardness of the sole body. During production, the first reinforcement portion, the second reinforcement portion and the heel reinforcement portion are first press-fitted separately to form independent accessories, and then hot-pressed with the sole body.

[0023] The first reinforcement 3 corresponds to the first metatarsophalangeal joint of human foot, the second reinforcement 4 corresponds to the fifth metatarsophalangeal joint of human foot, and the heel reinforcement 5 is located at the heel tail end. The first reinforcement 3, the second reinforcement 4 and the heel reinforcement 5 are the three zones where the sole wears out more seriously when walking, particularly near the sole edge. Therefore, the material hardness of these three parts is greater than the sole body hardness, and the end area of the first reinforcement and the second reinforcement near the sole body edge is larger, and the end area of the first reinforcement and the second reinforcement near the middle of the sole body is smaller, which strengthens the wear resistance in the three zones. Simultaneously, the material of the sole body is softer than these three zones, so that the sole body overall weight is light, and when ensuring the wear resistance of the sole, the comfort of wearing is taken into account.

[0024] The bottom of the sole body 1 has multiple protrusions 11 with the same hardness as the sole body. The sole body protrusions 11 are integrally formed with the sole body. The outer surfaces of the first reinforcement 3, second reinforcement 4, and heel reinforcement 5 can be flush with the outer surfaces of the protrusions of the sole body. Alternatively, the first reinforcement 3, second reinforcement 4, and heel reinforcement 5 can be taller than the sole body protrusions, that is, the first reinforcement 3, second reinforcement 4, and heel reinforcement 5 slightly protrude from the sole body protrusions 11.

[0025] The upper end of the sole body is provided with grooves at the forefoot, heel, and arch. Shock absorbers 6 are located within the forefoot groove 12 and heel groove 13, while a carbon fiber plate 7 is located within the arch groove 14. The shock absorbers are made of shock-absorbing material, providing a cushioning effect and alleviating foot fatigue. A carbon fiber plate is located at the waist and arch for support and torsion resistance.
