Abstract

The invention belongs to the technical field of shoe soles, specifically a polyurethane shoe sole, which includes an inner layer that can be in contact with the sole of the foot and a bottom layer that can be in contact with the ground; it includes a heating module, a shock-absorbing module and a breathable module; the heating module includes a sliding plate, Connecting rod, friction plate, No. 1 cavity and return spring; there are two No. 1 cavities at the front end of the bottom layer, and the No. 1 cavity is I-shaped; a friction plate is placed on the upper part of the No. 1 cavity, and the friction The upper end of the plate is in contact with the inner layer; the middle part of the No. 1 cavity is provided with a connecting rod, and the upper end of the connecting rod is fixedly connected with the lower end of the friction plate; the lower part of the No. The upper end of the part is fixedly connected with the lower end of the connecting rod; the upper part of the No. 1 cavity is fixedly connected with a return spring at the position towards the rear end, and the other end is fixedly connected with the friction plate; Problem with cold feet when walking.

Description

Technical field [0001] The present invention belongs to the field of sole technology, specifically a polyurethane sole. Background [0002] Polyurethane is a polymer with a repeating structural unit of carbamate segments made by the reaction of isocyanates with polyols. Compared with ordinary rubber soles, polyurethane soles have the characteristics of light weight and good wear resistance. The polyurethane sole uses polyurethane resin as the main raw material to solve the problems of easy bottoming of domestic plastic soles and recycled rubber soles and the problems of easy opening of rubber soles and rubber soles. By adding various additives, the polyurethane sole has been greatly improved in terms of wear resistance, oil resistance, electrical insulation, anti-static and acid and alkali resistance. The author's research adopts new processing technology, molding technology and appearance design, and the safety performance of shoes is more stable, and it is beautiful and comfor...
