Double-damping sneaker sole with double-nested structure and manufacture method of damping balls

Abstract

The invention discloses a double-damping sneaker sole with a double-nested structure and a manufacture method of damping balls. The double-damping sneaker sole comprises a sneaker insole and a rubber outsole, double-nested damping balls are further arranged between the sneaker insole and the rubber outsole, the sneaker insole is provided with fitting grooves for accommodating the damping balls, the number of the damping balls is two or more, the damping balls are symmetrically arranged in the sneaker insole, the number and position of the fitting grooves formed in the sneaker insole correspond to that of the damping balls, the damping ball comprises an inner layer elastic ball and outer layer ball rubber, the inner layer elastic ball is made of elastic foam materials, and the outer layer ball rubber is made of elastic rubber materials. When under pressure, not only are respective damping functions of the inner layer elastic ball and the outer layer ball rubber realized, but also the interaction between the inner layer elastic ball and the outer layer ball rubber further delivers better damping effect.

Description

technical field [0001] The invention relates to the technical field of footwear, in particular to a double shock-absorbing sports shoe sole with a double nesting structure and a method for making a shock-absorbing sphere. Background technique [0002] Shoes, as people's daily necessities, undertake functions such as keeping warm, protecting, and looking beautiful. In some occasions, such as outdoor activities, training, rescue and other occasions, it is usually required that the shoes have some shock-absorbing functions to meet people's needs for the safety of legs and feet. Shock-absorbing shoes are a kind of functional shoes, which mainly refer to shoes that can absorb the impact force of the feet and protect the feet. People attach great importance to the shock-absorbing effect of shoes, because the shock-absorbing effect of shoes directly affects their wearing comfort and sports effect, especially in the field of competitive sports. A pair of shoes with good shock-absor...

AI Technical Summary

Problems solved by technology

[0005] 2. Oil-pack shock absorption: semi-liquid gel is used as the absorption medium of the buffer force, but its fluidity is poor, and it is not suitable for fast-moving types;

[0006] 3. Material shock absorption: The shock-absorbing polyurethane material is mainly used to achieve the shock-absorbing effect, and its shock-absorbing effect is limited, and it is difficult to achieve the ideal shock-absorbing requirements simply by relying on shock-absorbing materials;

[0007] 4. Shock-absorbing insoles: The shock-absorbing effect is mainly achieved through shock-absorbing insoles, but the materials used in shock-absorbing insoles generally have good elasticity, but poor air permeability and comfort. Since the insoles are in direct contact with the soles of the feet, And sealed inside the shoes, it is easy to cause problems such as sweaty feet or smelly feet;

[0008] 5. Spring shock absorption: the shock absorption effect is performed by setting the spring structure. However, when a large impact force is received, only the independent spring is used for shock absorption, which will easily cause the elastic fatigue of the spring and affect its shock absorption effect. shortened service life

[0009] As consumers' requirements for finished shoes continue to increase, the traditional shock-absorbing shoes listed above are basically composed of a single shock-absorbing material to form an overall sole structure of the shock-absorbing material. Even if there is a combination of two shock-absorbing materials, there are many It is difficult to integrate the properties of the two materials and exert a better shock absorption effect for the upper and lower structures or completely separate and independent shock absorption structures
