Shoe sole with spiral breathable waterproof element

Abstract

The invention relates to a shoe sole and provides a shoe sole with a spiral breathable waterproof element, which has a simple structure, can be manufactured conveniently and can effectively achieve breathability and waterproof effect. The shoe sole comprises a sole body and the spiral breathable waterproof element, the spiral breathable waterproof element comprises a threaded rod with threads on the outer surface and a cap, the cap comprises an inner cap layer and an outer cap layer, the inner cap layer is sheathed with the outer cap layer, a sealing structure is arranged between the inner cap layer and the outer cap layer, a first vent hole is formed in the inner cap layer, a second vent hole is formed in the outer cap layer, the inner cap layer and the outer cap layer can rotate relatively to achieve communication or separation of the first vent hole and the second vent hole, a mounting slot, which is provided with an outward opening and into which the threaded rod is inserted to be fixed, is formed in the side part of the sole body, an air vent penetrating through the upper surface of the sole body is formed in the wall of the mounting slot and is disposed between the adjacent threads of the threaded rod, and the cap is arranged on the opening of the mounting slot.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a shoe sole provided with a spiral air-permeable and waterproof element. Background technique [0002] Shoes are an indispensable daily necessities in people's daily life. The comfort of shoes depends not only on the soles conforming to human anatomy, but also on whether the shoes can discharge the water vapor generated by perspiration in the shoes, so as to avoid the dampness and heat in the shoes, and bacteria breed. Most of the foot sweat in the shoes occurs between the soles of the feet and the soles. The sweat here is difficult to evaporate, and will gather on the insoles and insoles that the feet step on, especially resin soles. This problem is particularly important. Penetration through the sole is completely blocked, in order to solve this technical problem, [0003] In the prior art, a method of setting breathable waterproof cloth and vent holes in the sole is adopted to achieve breathab...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, a method of setting breathable waterproof cloth and vent holes in the sole is adopted to achieve breathable and waterproof effect. The vent holes communicate the inner space of the sole with the outside world, and the breathable waterproof cloth is used to block water and pass air, so that the inside of the shoe The hot and humid air leaks out, and the fresh air from the outside enters to realize ventilation, but the breathable waterproof sole has the following defects: 1. The inner space of the sole is narrow and small, and the space capacity for accommodating the hot and humid air is limited. If the air in the shoe cannot be discharged in time, There may be a problem of backflow of hot air; 2. The installation structure of the breathable waterproof cloth is not ideal, the reliability is poor, it is easy to fall off and shift, and it cannot guarantee that it can still filter water after wearing it for a long time, which will affect the waterproof performance; 3. The structure is complex, high manufacturing cost
