Description

Technical Field

[0001] This utility model relates to the field of shoe technology, specifically to a shoe sole and shoe with good wear resistance. Background Technology

[0002] In the field of footwear technology, the performance of the sole has always been a key factor affecting the overall quality and lifespan of shoes. With the improvement of people's living standards and the increasing functional requirements of footwear products, the abrasion resistance of soles is receiving more and more attention.

[0003] Currently, there are various types of shoe soles on the market, made from a wide variety of materials, commonly including rubber, polyurethane, and ethylene-vinyl acetate copolymer (EVA). However, due to the inherent characteristics of their manufacturing materials, some shoe soles exhibit obvious defects during actual wear. Specifically, the forefoot and heel of the sole are prone to wear.

[0004] A search revealed that existing technologies also include some solutions for improving the abrasion resistance of shoe soles, such as adding abrasion-resistant coatings to the sole surface, using special sole pattern designs, and adding abrasion-resistant structures to the sole.

[0005] Adding abrasion-resistant structures to the sole requires consideration of how to design these structures and how to connect them to the sole. Utility Model Content

[0006] In view of the problems pointed out in the background art, this utility model proposes a shoe sole and shoe with good wear resistance to solve the above-mentioned technical problems.

[0007] The technical solution of this utility model is implemented as follows:

[0008] A shoe sole with good abrasion resistance includes a shoe sole body, a front abrasion-resistant wrapping body and a rear abrasion-resistant wrapping body respectively connected to the lower sides of the front and rear ends of the shoe sole body, and an abrasion-resistant strip arranged along the front and rear direction and fixedly connected to the front and rear abrasion-resistant wrapping bodies. The middle part of the abrasion-resistant strip is arched upward and fixedly connected to the shoe sole body. The hardness of the abrasion-resistant strip is greater than the hardness of the front and rear abrasion-resistant wrapping bodies.

[0009] The present invention is further configured such that both the front and rear abrasion-resistant wrapping bodies have wrapping cavities that are adapted and connected to the front and rear ends of the sole body, respectively.

[0010] The present invention is further configured such that the front end of the wear-resistant strip is widened, and the front wear-resistant wrapping body is provided with a front connecting groove that is adapted to and connected to the front end of the wear-resistant strip.

[0011] The present invention is further configured such that the rear end of the wear-resistant strip extends upward and is fixedly connected to the rear side of the rear wear-resistant wrapping body, and the lower side and rear side of the rear wear-resistant wrapping body are provided with a rear connecting groove adapted to and connected to the rear end of the wear-resistant strip, and the wear-resistant strip is provided with an upwardly protruding limiting part, which abuts against the front side of the rear wear-resistant wrapping body.

[0012] The present invention is further provided that the lower side of the wear-resistant strip is provided with a textured groove along its length.

[0013] The present invention is further configured such that the wear-resistant strip is made of hard plastic, and the front wear-resistant wrapping body and the rear wear-resistant wrapping body are made of rubber.

[0014] The present invention is further configured such that a limiting groove connected to the limiting part is provided on the front side of the rear wear-resistant wrapping body.

[0015] A shoe includes a sole and an upper, wherein the sole is the sole described above.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] The shoe sole and shoe with good wear resistance provided by this utility model have a front wear-resistant wrapping body and a rear wear-resistant wrapping body respectively set at the front and rear ends of the sole body. This enhances the wear resistance of the front and rear ends of the sole. At the same time, the front wear-resistant wrapping body and the rear wear-resistant wrapping body are fixedly connected by a wear-resistant strip, thus fixing the distance between the front wear-resistant wrapping body and the rear wear-resistant wrapping body. This makes it easier to find the correct connection position when the front wear-resistant wrapping body and the rear wear-resistant wrapping body are fixed to the sole body. Moreover, the hardness of the wear-resistant strip is greater than that of the front wear-resistant wrapping body and the rear wear-resistant wrapping body, which can further enhance the wear resistance of the sole.

[0018] The front end of the wear-resistant strip is widened so that the front end of the wear-resistant strip can be fitted and connected to the front connecting groove, forming a limiting structure in the front and back directions to prevent the front end of the wear-resistant strip from separating from the front wear-resistant wrapping body due to pulling.

[0019] The rear end of the wear-resistant strip is wrapped around the rear side of the rear wear-resistant wrapping body, and the limiting part on the wear-resistant strip abuts against the front side of the rear wear-resistant wrapping body. This makes the rear end of the wear-resistant strip and the rear wear-resistant wrapping body fixedly connected in the front-back direction, preventing the rear end of the wear-resistant strip from separating from the rear wear-resistant wrapping body due to pulling.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] For reference as follows Figures 1-3 The present invention will be described as follows:

[0027] Example: A shoe sole with good abrasion resistance includes a sole body 1, and a front abrasion-resistant wrap 2 and a rear abrasion-resistant wrap 3 respectively connected to the lower sides of the front and rear ends of the sole body 1, forming direct protection for easily worn areas. This split wrap design can specifically reinforce the front push-off friction area and the rear impact landing area. Compared with the traditional integral abrasion-resistant layer design, it can precisely improve the abrasion resistance of key parts and reduce material consumption in unnecessary areas, achieving a balance between cost and performance.

[0028] It also includes a wear-resistant strip 4 that is set along the front and back direction and fixedly connected to the front wear-resistant wrap 2 and the rear wear-resistant wrap 3. The middle part of the wear-resistant strip 4 is arched upward and fixedly connected to the sole body 1.

[0029] The fixed connection of the abrasion-resistant strip 4 clearly defines the relative positions of the front and rear abrasion-resistant wraps, solving the spacing deviation problem that easily occurs during the installation of traditional split abrasion-resistant structures. During the production and assembly process, the preset length and curvature of the abrasion-resistant strip 4 can ensure that the front abrasion-resistant wrap 2 and the rear abrasion-resistant wrap 3 are precisely aligned with the stress centers at the front and rear ends of the sole, improving assembly efficiency and structural stability.

[0030] The arched structure in the middle forms an elastic support point. When the sole is subjected to ground reaction force, the arched part can absorb part of the impact force through deformation, reducing the stress directly transmitted to the sole body, thereby reducing the fatigue wear of the body material. At the same time, the arched structure makes the abrasion strip 4 and the sole body form a three-point support (both ends and the middle), enhancing the bending resistance of the entire abrasion protection system.

[0031] The abrasion strip 4 has a higher hardness than the front abrasion-resistant wrap 2 and the rear abrasion-resistant wrap 3. During the wear process of the sole, the abrasion strip 4, which has a higher hardness, can preferentially contact the raised particles on the ground and protect the surrounding wrap material through its own lower wear rate, forming a "rigid protective skeleton".

[0032] The front and rear ends of the abrasion-resistant strip 4 can be bonded to the front abrasion-resistant wrap 2 and the rear abrasion-resistant wrap 3 with high-strength adhesive, and the front abrasion-resistant wrap 2 and the rear abrasion-resistant wrap 3 can be bonded to the sole body 1 with high-strength adhesive.

[0033] The front end of the abrasion-resistant strip 4 is widened, and the front abrasion-resistant wrap 2 has a front connecting groove 6 that adapts and connects to the front end of the abrasion-resistant strip 4. This design creates a limiting structure during assembly, with the side walls of the widened portion contacting and fitting against the side walls of the groove. When the front end of the sole is subjected to the friction force of stepping on the ground, the front end of the abrasion-resistant strip 4 will be subjected to a backward pulling force. At this time, the structure of the widened portion and the groove wall of the front connecting groove 6 generate a mutually restraining force.

[0034] The rear end of the wear-resistant strip 4 extends upward and is fixedly connected to the rear side of the rear wear-resistant wrapping body 3. The lower and rear sides of the rear wear-resistant wrapping body 3 are provided with rear connecting grooves 7 that are adapted to connect with the rear end of the wear-resistant strip 4. The wear-resistant strip 4 is provided with an upwardly protruding limiting part 8, which abuts against the limiting groove 10 on the front side of the rear wear-resistant wrapping body 3. Front-back direction limiting: The limiting part 8 is embedded in the limiting groove 10 on the front side of the rear wear-resistant wrapping body 3, forming a rigid stop in the front-back direction. When the rear end of the wear-resistant strip is subjected to a forward thrust, the limiting part 8 abuts against the front wall of the limiting groove 10.

[0035] The combined design of widened front end and three-dimensional connection at the rear end upgrades the connection between the wear-resistant strip 4 and the front and rear wear-resistant wrapping bodies from a traditional two-dimensional planar fixation to a three-dimensional spatial constraint. Due to the improved reliability of the connection points, the wear-resistant strip 4 can continue to provide support and wear resistance during long-term use.

[0036] Both the front abrasion-resistant wrap 2 and the rear abrasion-resistant wrap 3 have wrapping cavities 5 that are adapted and connected to the front and rear ends of the sole body 1, respectively. The front and rear ends of the sole body 1 are connected to the wrapping cavities 5 of the front abrasion-resistant wrap 2 and the rear abrasion-resistant wrap 3, respectively.

[0037] The enclosing cavity 5 adopts a three-dimensional contour design, and the internal contour of the cavity is adapted to the shape of the front and rear ends of the sole body 1.

[0038] The lower side of the wear-resistant strip 4 has grooves 9 along its length. The grooves are V-shaped or rectangular, which maximizes the contact area without reducing the structural strength of the wear-resistant strip.

[0039] The wear-resistant strip 4 is made of hard plastic, while the front wear-resistant wrapping 2 and the rear wear-resistant wrapping 3 are made of rubber.

[0040] A shoe includes a sole and an upper, wherein the sole is the sole described above.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
