Description

Technical Field

[0001] This utility model relates to the field of sports shoes, specifically a highly elastic, lightweight, 45-degree anti-slip sole structure. Background Technology

[0002] In the footwear industry, the design and performance of the sole structure play a crucial role in the overall quality and wearing experience of shoes. Currently, traditional sole structures face numerous challenges in terms of connection methods and performance improvement.

[0003] In terms of connecting different parts of the sole, common connection methods are quite cumbersome. Connecting different layers of the sole often requires complex external positioning tools and methods to achieve precise alignment. For example, when connecting the abrasion-resistant insole to the outsole overlay, complex measurements and markings are usually required first, followed by multiple processes to ensure accurate positioning before fixing. This is not only time-consuming and labor-intensive but also inefficient. Furthermore, this connection method lacks stability. During long-term wear and walking, various external forces can cause displacement or separation between the layers, affecting the shoe's lifespan and wearing safety.

[0004] In terms of sole performance, improving the abrasion resistance and strength of traditional soles faces challenges. The abrasion layer of ordinary soles often uses only a single material, resulting in limited abrasion resistance and overall strength. When the shoe wears down to a certain extent, the performance of the abrasion layer rapidly declines, shortening the shoe's lifespan. Furthermore, the bonding strength between different layers in traditional soles is not ideal. For example, the elastic layer and the foam layer are usually simply bonded together or connected using ordinary methods. During daily wear, with foot movement and pressure changes, these two layers are prone to loosening and separation, severely affecting the shoe's comfort and functionality, and failing to meet consumers' demands for high-quality shoes. Therefore, those skilled in the art have provided a highly elastic, lightweight, 45-degree anti-slip sole structure to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a highly elastic and lightweight 45-degree anti-slip shoe sole structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A highly elastic and lightweight 45-degree anti-slip shoe sole structure includes a sole covering layer and an elastic layer, a foam layer, and a breathable pad disposed on the sole covering layer from bottom to top. The bottom periphery of the sole covering layer has an inverted trapezoidal annular groove integrally formed. The bottom of the sole covering layer is provided with an abrasion-resistant shoe bottom layer. A trapezoidal retaining ring is integrally formed and inserted into the inverted trapezoidal annular groove along the outer edge of the abrasion-resistant shoe bottom layer. The abrasion-resistant shoe bottom layer is bonded to the sole covering layer.

[0008] As a further embodiment of this utility model: the top of the sole covering layer is integrally formed with a shoe upper connecting protrusion for connecting with the shoe upper, and the side wall of the sole covering layer is integrally formed with a plurality of parallel decorative protrusions.

[0009] As a further embodiment of this utility model: the bottom of the wear-resistant shoe is integrally formed with staggered trapezoidal opening grooves and anti-slip protrusions, and the bottom of the anti-slip protrusions is provided with V-shaped grooves for anti-slip.

[0010] As a further improvement of this utility model: multiple wear-resistant rubber strips are provided inside the bottom layer of the wear-resistant shoe, and the wear-resistant rubber strips cover the inside of the bottom layer of the wear-resistant shoe.

[0011] As a further improvement of this utility model: a plurality of foam connection holes are evenly provided above the elastic layer, and the foam connection holes are circular or polygonal.

[0012] As a further improvement of this utility model: the bottom of the foam layer is filled inside the foam connection card hole, and the foam layer constructs a three-dimensional mesh-like fluffy structure through microporous foaming technology, achieving a density gradient distribution while maintaining a hardness of 45±2 Shore C.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model achieves the connection between the wear-resistant shoe bottom layer and the sole covering layer by setting an inverted trapezoidal groove and a trapezoidal retaining ring, and then using adhesive bonding. This allows for the positioning connection between the two, and the mating connection can be achieved directly through positioning, eliminating the trouble of using external auxiliary positioning to achieve the connection, greatly improving efficiency and saving time and effort.

[0015] 2. This utility model improves the overall strength of the abrasion-resistant shoe sole by embedding abrasion-resistant rubber strip inside the sole. It also enhances the abrasion resistance and durability when the abrasion-resistant rubber strip is worn down. By opening foam connection holes in the elastic layer to connect with the foam layer, the connection strength between the two can be greatly improved. Moreover, it can realize the docking and positioning of the two, which is extremely convenient and quick. Attached Figure Description

[0022] 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.

[0023] Please see Figures 1-5 In this embodiment of the utility model, a high-elasticity, lightweight, 45-degree anti-slip shoe sole structure includes a sole covering layer 1 and an elastic layer 5, a foam layer 4, and a breathable pad 3 disposed on the sole covering layer 1 from bottom to top. The bottom periphery of the sole covering layer 1 is integrally formed with an inverted trapezoidal groove 103. The bottom of the sole covering layer 1 is provided with a wear-resistant shoe bottom layer 2. A trapezoidal retaining ring 203 is integrally formed and inserted into the inverted trapezoidal groove 103 at the outer edge of the upper part of the wear-resistant shoe bottom layer 2. The wear-resistant shoe bottom layer 2 is bonded to the sole covering layer 1.

[0024] By adopting the above technical solution, after setting the inverted trapezoidal groove 103 and the trapezoidal retaining ring 203 to cooperate, the wear-resistant shoe bottom layer 2 and the shoe sole covering layer 1 are connected by adhesive. The positioning connection between the two can be achieved directly through positioning, eliminating the trouble of using external auxiliary positioning to achieve the connection, greatly improving efficiency and saving time and effort.

[0025] Among them, the top of the sole covering layer 1 is integrally formed with a shoe upper connecting protrusion 102 for connecting with the shoe upper, and the side wall of the sole covering layer 1 is integrally formed with several parallel decorative protrusions 101, which can play a decorative role.

[0026] Among them, the bottom of the wear-resistant shoe bottom layer 2 is integrally formed with staggered trapezoidal opening grooves 201 and anti-slip protrusions 202. The bottom of the anti-slip protrusions 202 is provided with V-shaped grooves 2021 for anti-slip, which can ensure the anti-slip effect of the wear-resistant shoe bottom layer 2.

[0027] The wear-resistant shoe bottom layer 2 has multiple wear-resistant rubber strips 204 inside. The wear-resistant rubber strips 204 cover the inside of the wear-resistant shoe bottom layer 2. By embedding the wear-resistant rubber strips 204 inside the wear-resistant shoe bottom layer 2, the overall strength of the wear-resistant shoe bottom layer 2 can be improved, and when the wear-resistant rubber strips 204 are worn, their wear resistance is enhanced, and their durability is improved.

[0028] The elastic layer 5 has several evenly spaced foam connection holes 501, which are circular or polygonal. The bottom of the foam layer 4 is filled inside the foam connection holes 501. The foam layer 4 uses microporous foaming technology to construct a three-dimensional mesh-like fluffy structure, achieving a density gradient distribution while maintaining a hardness of 45±2 Shore C. This biomimetic design reduces the compression deformation of the midsole by 12% while increasing the impact absorption rate to 89%, resulting in a 32% weight reduction compared to traditional EVA materials.

[0029] By adopting the above technical solution, the connection between the elastic layer 5 and the foam layer 4 can be achieved by opening foam connection holes 501 on the elastic layer 5, which can greatly improve the connection strength between the two and realize the docking connection positioning of the two, which is extremely convenient and quick.
