AI Technical Summary
Traditional shoe sole manufacturing processes are complex and inefficient, with uneven connection methods. A single material cannot simultaneously meet the requirements for support and flexibility, affecting comfort and service life.
The shoe features a composite sole design, including an outsole, midsole, and insole. It utilizes anti-deviation structures and cavity structures to improve connection stability and elasticity, and achieves fixation through ring walls and protruding ridge structures. The midsole and insole have cavities at the heel to increase elasticity.
The manufacturing process has been simplified, avoiding the problem of glue coming undone, improving the comfort and elasticity of the sole, preventing the midsole from shifting, and extending the lifespan of the shoes.

Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to sole manufacturing technical field, especially a kind of high elastic combined sole. BACKGROUND
[0002] In the manufacture and installation of traditional sole, the connection between sole and upper is usually adopted relatively complex process. For example, traditional sewing process needs a large amount of manual operation, not only time-consuming and laborious, but also higher technical requirements for workers, and the production efficiency is low. Although the paste mode using glue is relatively simple, there are problems such as uneven glue spreading and long curing time, which affect the production progress.
[0003] Traditional single material sole is difficult to meet multiple performance requirements. For example, in order to pursue good supportability, some soles are made of hard material, which leads to insufficient flexibility, poor comfort when wearing, and easy to feel tired after a long walk or exercise. Some soles with soft and comfortable selling points are also lacking in wear resistance and supportability, which seriously affects the overall quality and service life of the shoes. SUMMARY
[0004] The utility model aims at solving the shortcomings in the prior art and provides a high elastic combined sole.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0006] A high elastic combined sole, characterized in that it comprises an outsole and a midsole; the outsole is provided with a receiving groove for the midsole; the upper surface of the outsole and the lower bottom of the midsole are provided with an anti-deviation structure for preventing the midsole from deviating; and the lower bottom surface of the midsole at the heel is further provided with a cavity.
[0007] A preferred technical feature: the cavity is located inside the midsole.
[0008] A preferred technical feature: the cavity comprises a groove recessed inwardly on the lower bottom surface of the midsole.
[0009] A preferred technical feature: the groove is a semicircular structure.
[0010] A preferred technical feature: the anti-deviation structure comprises a groove on the upper surface of the outsole and a protrusion on the lower bottom of the midsole; the protrusion is located in the groove and is adapted to the groove.
[0011] A preferred technical feature: the protrusion of the midsole and the groove of the outsole are arranged away from the elastic cavity.
[0012] A preferred technical feature: it further comprises an insole; the insole is placed above the midsole; and the insole at the heel is also provided with a cavity.
[0013] A preferred technical feature: the cavity is an inwardly recessed groove on the bottom surface of the insole, and the groove is located on the bottom surface of the heel part of the insole.
[0014] A preferred technical feature: the outsole includes a body; an annular wall extending upward from the body; the annular wall forms a receiving groove in the midsole. Beneficial effects
[0015] The beneficial effects of this utility model are as follows: The advantages of using a combined sole are as follows: 1. The production of the finished sole saves on processes such as gluing and drying; it also avoids problems such as glue detachment; 2. The upper surface of the outsole and the lower surface of the midsole are provided with a fixing structure that fixes each other; this mainly prevents the midsole from shifting during wear; 3. Rubber outsoles, especially the inner soles of skate shoes, are relatively hard, affecting their comfort. In this utility model, a cavity is provided at the heel of the midsole and / or insole to increase its elasticity. Attached Figure Description
[0016] To more clearly illustrate the embodiments of the present invention, the drawings used in the implementation process are briefly described below:
[0017] Fig. 1 This is a schematic diagram of the overall structure of the high-elastic composite sole;
[0018] Fig. 2 This is a schematic diagram of the base structure;
[0019] Fig. 3 This is a schematic diagram of the structure of embodiment 1 of the midsole;
[0020] Fig. 4 This is a schematic diagram of the structure of embodiment 2 of the midsole;
[0021] Fig. 5 This is a schematic diagram of the insole structure; Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figs. 1-3 A high-elastic composite shoe sole includes an outsole 1, a midsole 2, and an insole 3; the outsole 1 includes an annular wall 11 extending upward along its periphery, the annular wall 11 forming an annular groove, and the midsole 2 is placed in the groove; the upper surface of the outsole 1 and the lower surface of the midsole 2 are provided with a deviation structure to prevent the midsole from deviating; the lower surface of the midsole 2 at the heel is also provided with a cavity 21.
[0024] In a preferred embodiment, the cavity 21 in the heel of the midsole has two structures: 1. The cavity is located inside the midsole, like an air bag; 2. The cavity is a groove on the lower surface of the midsole, which is concave inwardly; the groove is semicircular in structure.
[0025] In a preferred embodiment, the semicircular groove is directly covered on the upper surface of the outsole 1.
