Problems solved by technology

Since the outsole of ethylene-vinyl acetate copolymer is made of one injection in the mold and foamed outside the mold, the shoe mold used is made by reducing the size of a certain proportion, and the density of the outsole of ethylene-vinyl acetate copolymer is very small, so it cannot There are tightly arranged ventilation grooves on the outsole, so it is impossible to set the ventilation device on the ethylene-vinyl acetate copolymer combination sole sports shoes

Embodiment Construction

[0012] Such as Figure 1-Figure 5 As shown, the present embodiment comprises ethylene-vinyl acetate copolymer outsole (1), outsole patch (15), midsole (14), movable insole (18).

[0013] Such as figure 1 As shown, a mounting hole occupying a certain area is provided at the sole of the sole of the ethylene-vinyl acetate copolymer (1), and the mounting hole is inlaid with an independent core block (2) provided with several ventilation grooves (13). The heel portion of the ethylene copolymer outsole (1) is also provided with a mounting hole, and an air bag (6) is placed in the mounting hole. The exhaust one-way valve (4) is supported on the shoe waist connecting piece (3) (as figure 2 As shown), it is connected with the air bag (7) through a hose (5) outsourcing, and a movable soft support (10) is provided in the hose (5), so that the hose (5) can be bent when the hose (5) is bent. It will not be clamped, ensuring the smoothness of the pipeline. The meeting point of the vent...

Abstract

The present invention relates to a kind of sport shoes. Its sole is made up by using ethylene-polyvinylacetate copolymer and is equipped with an air-changing device. Said invention also provides the concrete structure of said air-changing device. As compared with existent technology said invention not only raise the air permeability and comfort ability of high-grade sport shoes, but also has the advantages of large air-changing quantity and long service life, etc.

Description

technical field [0001] The invention relates to sports shoes with sanitary equipment, in particular to an ethylene-vinyl acetate copolymer composite bottom sports shoe with a ventilation device on the sole. Background technique [0002] At present, the soles of all kinds of sports shoes of world famous brands are composed of ethylene-vinyl acetate copolymer outsoles and rubber patches, which are called super shoe materials by the shoe industry. Since the outsole of ethylene-vinyl acetate copolymer is made of one injection in the mold and foamed outside the mold, the shoe mold used is made by reducing the size of a certain proportion, and the density of the outsole of ethylene-vinyl acetate copolymer is very small, so it cannot On the outsole, closely arranged ventilation grooves are arranged, so it is impossible to arrange the ventilation device on the ethylene-vinyl acetate copolymer combined bottom sports shoes. Contents of the inv...
