Embodiment Construction

[0017] Table 1 shows the tearing load test data of the midsole without mesh and inlaid hexagonal or circular mesh shape mesh, where the area of ​​a single mesh is 5mm 2 , the grid area in the mesh 2 accounts for 90% of the entire mesh area, and the height of the protrusion 3 is 0.5mm. When using the crack load method, the laboratory researchers first thought of the hexagonal shape, that is, the shape of the honeycomb. This shape can fully disperse the pressure well during the stretching and tearing process in all directions. For other shapes, the circle is the most suitable. Close to the hexagon, in advanced mathematics, the polygon is infinitely close to the circle, but the circle is easy to deform under the force and the pressure distribution is not as good as the hexagon, and other geometric shapes are not as good as the six in terms of force resistance, deformation resistance and pressure distribution. polygon. The tensile testing machine conforms to the regulations of QB...

Abstract

The invention relates to a sole, in particular to an insole structure of sneakers. The insole structure comprises an insole made of an EVA or a polyurethane material and net cloth provided on the underside and the side of the insole; the net cloth and the EVA insole are integrally foamed and molded; and the EVA insole protrudes from grids of the net cloth to form a plurality of protrusions. The insole structure uses a cobweb structure for reference, adopts advanced EVA foaming technology and once molding of the net cloth and forms one layer of the cobweb structure by embedding the net cloth in the underside and the side of the insole in the EVA raw material foaming and molding process to improve and increase the tearing resistance, wearing resistance and tensile resistance of the insole, also improve the stability of the insole on the heel motion, have three-dimensional shape effect at the same time, and close to and realize partial functions of the double-density insole.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a sports shoe midsole structure. Background technique [0002] The role of the midsole structure of sports shoes is to provide cushioning, stability and flexibility, and it is one of the most important parts of sports shoes. At present, the midsole of sports shoes is generally made of EVA or polyurethane foam, and different sports performances can be realized by controlling the raw material formula, temperature during production, and molding time. At present, one of the cutting-edge technologies of midsole is to design and manufacture it with double density according to human body sports biomechanics and sports anatomy. It is difficult to make midsole, and it is difficult to find sports shoes with double-density midsole in the domestic market. Therefore, the comprehensive performance of the midsole structure of ordinary sports shoes is not high. Contents of the invention [0003] The technic...
