Problems solved by technology

But strengthening the strength of the shock-absorbing parts means reducing the up-and-down elasticity and expansion space of the shock-absorbing parts, which will inevitably affect the air flow in the air chamber inside the shock-absorbing parts
This is a conflicting issue

Embodiment Construction

[0027] Such as figure 1 , figure 2 Shown, a kind of shock-absorbing sole described in Embodiment 1 of the present invention;

[0028] The midsole (100) adopts an injection molding process and is composed of PU injection molding material and a shock-absorbing component (300) embedded in the heel. The bottom position of the shock-absorbing component (300) should be at the same level as the extension line below the midsole (120) or above the level.

[0029] The bottom (120) heel portion of the midsole (100) forms a groove from bottom to top that can embed the shock absorbing component (300), an air output-input channel (111) and an air output-input duct (112) from the midsole (100) Top (110) forefoot position extends to heel always, passes through the connecting pipe of shock absorbing part (300) by connecting passage (122) and links to each other with the shock absorbing part (300) inner air storehouse in the groove with otch (332).

[0030] The shock absorbing part (300) ex...

Abstract

The invention discloses a shock-absorption sole, and specifically provides a comfortable and light shock-absorption sole with spring type reliable shock absorption performance and air bag type shock absorption performance at the same time. The shock-absorption sole comprises an insole and an outsole, wherein the insole adopts a PU injection molding process, the outsole is made of natural rubber, the shock absorption sole is provided with a shock-absorption component which is a hollow pad, and the upper center of the hollow pad is opened; the opening periphery of the shock-absorption component is upward extended with a convex edge to form a convex shape; the convex edge is provided with a plurality of outward radial notches from the center to the peripheral four radial directions; the insole is provided with an air import / export pipeline which is extended to the heel from the front sole part to communicate with the shock-absorption component; and the outsole, the insole and the shock-absorption component are fixed together to combine the advantages of the air bag type shock-absorption technology and the spring type reliable shock-absorption technology.

Description

technical field [0001] The invention relates to the shock absorption technology of shoe soles, in particular to a shock-absorbing shoe sole which has the reliable shock-absorbing performance of a spring and the comfort and lightness of an airbag-type shock absorption. Background technique [0002] Generally speaking, shoes are mainly designed and made for people to protect their feet during walking. In general, the structure of shoes can be divided into uppers that protect the feet and ankles, and soles that protect the soles of the feet, exert anti-skid performance and cushioning effects, and improve walking efficiency. The uppers are connected to the soles. [0003] The sole can be divided into insole, midsole and outsole. [0004] The common sole shock absorption technology is a fully enclosed shock-absorbing air bag based on the principle of aerodynamics, or a spring-type shock-absorbing principle of a similar shape such as a bow spring. [0005] Among them, once the s...
