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

Embodiment 1

[0025] refer to Figure 1 to Figure 3 , what embodiment 1 discloses is that a waterproof and breathable sole comprises a midsole 1 and a rubber bottom sheet 2 attached to the lower surface of the midsole, the lower surface of the midsole 1 is provided with a ventilation groove, and the ventilation groove is formed by A ring-shaped thread groove 3 formed by turning and winding from outside to inside, the groove cross section of the ring-shaped thread groove 3 is trapezoidal, and the groove depth of the ring-shaped thread groove 3 is 3.5mm , the width is 3mm, and the distance between adjacent turns of the ring-shaped thread groove 3 is 8mm; the outer end of the ring-shaped thread groove 3 is provided with a ventilation notch 31 extending to the outside of the midsole; There are multiple ring-shaped thread grooves 3, and each ring-shaped thread groove 3 is arranged in an array on the sole and heel of the midsole 1; the corresponding ring-shaped thread grooves on the upper surface...

Embodiment 2

[0027] refer to Figure 4 to Figure 6 , the structure of embodiment 2 is almost the same as that of embodiment 1, the difference is that in embodiment 2, the ring-shaped threaded groove 3 is arranged on the upper surface of the rubber base 2; and the lower surface of the rubber base 2 is provided with anti-skid patterns; The anti-slip pattern includes a plurality of quadrilateral anti-slip structures 21, the four corners of the quadrilateral anti-slip structures 21 are respectively provided with hexagonal anti-slip blocks, and connecting blocks are provided between adjacent hexagonal anti-slip blocks. Anti-slip strips are provided with triangular anti-slip blocks between adjacent connected anti-slip bars, and anti-slip grooves are provided on the surface of the triangular anti-slip blocks; adjacent quadrilateral anti-slip structures 21 share a connection anti-slip strip.

Embodiment 3

[0029] refer to Figure 7 , the structure of embodiment 3 is almost the same as that of embodiment 1, the difference is that there are only two ring-shaped thread grooves 3 in embodiment 3, and the number of turns of the two ring-shaped thread grooves 3 is respectively covered on the sole of the midsole 1 and heel.

[0030] In summary, the waterproof and breathable sole designed above has a simple structure, is convenient to manufacture, can effectively take into account both breathability and waterproof effects, and has strong practicability.

Abstract

The invention relates to a shoe sole, and provides a waterproof breathable shoe sole which is simple in structure and convenient to manufacture and can effectively achieve the breathable effect and the waterproof effect. The waterproof breathable shoe sole comprises an insole and a rubber bottom sheet arranged on the lower surface of the insole. A ventilating groove is formed between the insole and the rubber bottom sheet. The ventilating groove is an annular threaded groove formed by rotating and coiling a groove from outside to inside. A ventilating notch extending to the outside of the insole is formed in the outer end of the annular threaded groove. A ventilating hole penetrating through the upper surface and the lower surface of the insole is formed in the insole. The ventilating hole is located in the upper portion of the inner end of the annular threaded groove and communicated with the inner end of the annular threaded groove.

Description

technical field [0001] The invention relates to a shoe sole, in particular to a waterproof and breathable shoe sole. 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 breathable and waterproof effect. The vent...
