[0001] The utility model relates to the field of shoe soles, in particular to a double puncture-proof shoe sole. Background Art

[0002] Shoes are not only a tool for foot protection, but also reflect the culture and aesthetics of each era. From the triangular-shaped shoes of ancient Egypt to modern high-tech sneakers, shoes have continuously evolved to reflect humanity's pursuit of beauty, comfort, and functionality. Shoes are mainly composed of uppers, insoles, soles, and auxiliary components. The sole is the part of the shoe that directly contacts the ground, protecting the foot, cushioning pressure, and providing traction. Choosing the right sole material is crucial for improving comfort and adapting to specific needs. Shoes can be divided into casual shoes, sports shoes, thermal shoes, and anti-puncture shoes based on their function. These types of shoes can adapt to different scenarios and meet daily needs. One type of anti-puncture shoe generally uses steel plates inside the sole to increase its hardness. However, the sole surface is fragile and easily punctured. In addition, the sole surface of traditional anti-puncture shoes is in direct contact with the ground. When stepping on a long puncture object, the pressure generated by the sole is completely applied to the puncture object, making the sole easily punctured. Therefore, a double anti-puncture sole has been proposed. Utility Model Content

[0003] The purpose of the utility model is to provide a double puncture-proof sole, which can solve the problems that the surface of the sole of traditional puncture-proof shoes is fragile and easily punctured, and the sole is easily punctured when stepping on a puncturing object that is too long.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the utility model.

[0021] See also Figure 1-2 The embodiment of the utility model provides a technical solution: a double puncture-proof sole, the bottom layer 1 includes an injection-molded polyvinyl chloride material 101, and the upper end of the bottom layer 1 is provided with a hard layer 4, and the hard layer 4 includes a steel plate material 401. By providing the injection-molded polyvinyl chloride material 101, the wear resistance of the sole surface is improved. The injection-molded polyvinyl chloride material 101 is more wear-resistant than other materials. Compared with the traditional method of only using the steel plate material 401 inside the sole, the injection-molded polyvinyl chloride material 101 is further used on the sole surface to provide another guarantee for the anti-puncture of the sole, providing two lines of defense for the anti-puncture of the sole, and improving the anti-puncture ability of the sole. The sole of the injection-molded polyvinyl chloride material 101 is directly made by an injection molding machine in combination with various molds. PVC soles have high hardness and durability and are suitable for shoes that require high wear resistance. PVC soles are corrosion-resistant and have good chemical corrosion resistance, and can resist the erosion of most chemicals. PVC soles are also waterproof. PVC material itself has good waterproof properties and is suitable for use in humid environments. PVC soles are also resistant to high temperatures. Compared with other plastics, PVC soles can withstand higher temperatures without deformation. PVC soles are also impact-modified. By adding impact modifiers, PVC soles can increase elasticity while maintaining their hard properties and improve impact resistance. PVC materials are relatively cheap compared to other materials, have low production costs, simple manufacturing processes, and are suitable for mass production.

[0022] The lower end of the sole layer 1 is provided with a first cushioning layer 2 and a second cushioning layer 3, and the first cushioning layer 2 and the second cushioning layer 3 include rubber material 201. By arranging the first cushioning layer 2 and the second cushioning layer 3, the sole is lifted off the ground. When the shoe steps on a longer piercing object, the first cushioning layer 2 and the second cushioning layer 3 increase the distance from the sole to the ground, reducing the depth of the piercing object penetrating the sole, avoiding the piercing object from piercing the sole, and improving the anti-penetration ability of the sole. The thickness of the first cushioning layer 2 and the second cushioning layer 3 should be designed according to actual conditions. If the thickness is too thin, the anti-penetration effect of the sole cannot be achieved. If the thickness is too thick, the sole is too long, affecting the wearing comfort and aesthetics.

[0023] The lower end of the steel plate material 401 is bonded to the surface of the injection-molded polyvinyl chloride material 101. The steel plate material 401 is an important component of the anti-wear sole, which realizes that the anti-wear sole has anti-wear ability. The upper end of the rubber material 201 is bonded to the surface of the injection-molded polyvinyl chloride material 101. The rubber material 201 has high wear resistance, anti-slip properties, acid and alkali resistance and good shock absorption effect. The surfaces of the first cushion layer 2 and the second cushion layer 3 are provided with anti-slip grooves 2001. The anti-slip grooves 2001 are opened on the surfaces of the first cushion layer 2 and the second cushion layer 3. The anti-slip grooves 2001 increase the friction between the sole and the ground, further enhancing the anti-slip ability of the sole. The upper end of the hard layer 4 is provided with an elastic layer 5. The elastic layer 5 includes a high-elastic ethylene-vinyl acetate copolymer material 501. The lower end of the high-elastic ethylene-vinyl acetate copolymer material 501 is bonded to the surface of the steel plate material 401. The high-elastic ethylene-vinyl acetate copolymer material 501 is soft, elastic and chemical-resistant. The high-elastic ethylene-vinyl acetate copolymer material 501 has chemical corrosion resistance and other properties, improves the elasticity of the sole, and enhances the comfort of wearing. The upper end of the high-elastic ethylene-vinyl acetate copolymer material 501 is provided with a thermoplastic polyurethane rubber material 5001, and the lower end of the thermoplastic polyurethane rubber material 5001 is bonded to the surface of the high-elastic ethylene-vinyl acetate copolymer material 501. The thermoplastic polyurethane rubber material 5001 is a thermoplastic elastomer material with high strength, high toughness, excellent wear resistance and oil resistance. It reduces the impact of the ground on the heel during exercise, which is beneficial to protecting our ankles. The upper end of the elastic layer 5 is provided with a thermal insulation layer 6, and the thermal insulation layer 6 includes a silk cotton material 601. The lower end of the silk cotton material 601 is bonded to the surface of the high-elastic ethylene-vinyl acetate copolymer material 501. The silk cotton material 601 has the ability to keep warm and can protect our feet from frostbite in winter. Compared with other thermal insulation materials, the silk cotton material 601 has excellent air permeability, moisture absorption, moisture discharge and warmth retention.

[0024] Working principle: When in use, when preventing puncturing objects from piercing the sole, the hardness of the sole surface is enhanced by setting the injection-molded polyvinyl chloride material 101, and the steel plate material 401 set inside the sole cooperates with each other to provide two lines of defense for the sole to prevent puncturing objects from piercing the sole; when preventing puncturing objects that are too long from piercing the sole, the first cushioning layer 2 and the second cushioning layer 3 are set to make the sole leave the ground. When the shoe steps on a longer puncturing object, the first cushioning layer 2 and the second cushioning layer 3 will land first, and the sole is still some distance away from the ground, which reduces the depth of the puncturing object penetrating the sole and prevents puncturing objects that are too long from piercing the sole.

[0025] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
