Description

Technical Field

[0001] The utility model belongs to the technical field of PU soles, and more specifically, particularly relates to a PU sole with a surface covered with a wear-resistant and non-slip TPU film. Background Art

[0002] PU soles refer to soles made of polyurethane materials. Polyurethane is a thermoplastic polymer that can be processed by injection molding, calendering or other molding processes during the manufacturing process of soles. PU soles are widely used in the manufacture of various types of shoes such as sports shoes, casual shoes, work shoes, etc.

[0003] Although PU soles have a series of advantages, such as wear resistance, light weight, compression resistance and good durability, which make them a popular choice, the current PU soles have weak anti-slip properties. After being made into shoes for people to wear, they are easy to cause people to slip. In addition, the soles themselves are difficult to breathe, and moisture and sweat in the shoe compartment are easy to accumulate, causing bacteria to grow and odor to be generated, reducing the comfort and health of the shoes.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a PU sole with a wear-resistant and non-slip TPU film on the surface is provided, in order to achieve a more practical purpose. Utility Model Content

[0007] Furthermore, a ventilation chamber is provided inside the midsole, the bottom ends of several ventilation holes are connected to the ventilation chamber, and the top ends of several ventilation grooves are connected to the ventilation chamber.

[0008] Furthermore, the outer sole is made of polyurethane material, the midsole is made of ethylene vinyl acetate copolymer material, and the inner sole is made of leather material.

[0009] Furthermore, the wear-resistant and anti-slip film is made of thermoplastic polyurethane material.

[0010] Furthermore, the outer edge of the top end of the inner bottom is provided with a sewn hem.

[0011] Furthermore, the horizontal height of the middle portion is higher than the horizontal heights of the front portion and the rear portion.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The utility model discloses a PU sole with a surface covered with a wear-resistant and non-slip TPU film. By arranging a plurality of grip grooves, anti-slip blocks and anti-slip strips on the front and rear of the outsole, and cooperating with a wear-resistant and non-slip film made of thermoplastic polyurethane material covering the outsole, the anti-slip performance of the outsole is greatly improved, thereby preventing people from slipping when wearing the shoes and improving safety.

[0014] The utility model discloses a PU sole with a surface covered with a wear-resistant and non-slip TPU film. By arranging a plurality of ventilation grooves in the middle part of the outsole, and cooperating with the ventilation compartment of the midsole and the plurality of ventilation holes of the insole, the breathability of the sole is greatly improved, moisture and sweat in the shoe compartment can be effectively discharged, the growth of bacteria and the generation of odor are avoided, and the comfort and health of the shoes are improved.
