[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0026] Specific implementation examples are given below.
[0027] Please see Figures 1-5This utility model provides flame-retardant, heat-resistant, impact-resistant, and puncture-resistant safety shoes, including a sole 1 and an upper 2. The upper 2 is equipped with a surface protection mechanism, which enhances the impact resistance and puncture resistance of the upper 2. The surface protection mechanism includes a toe cap 3, made of synthetic rubber, hot-melt bonded to the edge of the upper 2 at the toe. The toe cap 3 provides impact and puncture protection for the user's toes. A protective plate 4 is located on the upper 2 at the toe, providing impact protection for the user's instep. Puncture-resistant plates 5 are located on both sides of the upper 2, providing puncture protection for the sides of the user's foot. A support heel counter 6 is located on the upper 2 at the ankle, enhancing the support of the upper 2 at the heel. The upper 2 has a multi-layer structure, consisting of a Cordura fabric 7, an aramid fabric 8, a fiberglass fabric 9, and an inner lining layer 10, arranged sequentially from the outside to the inside. The Cordura fabric 7... At the same weight, its durability is twice that of standard nylon fabric, three times that of polyester fabric, and ten times that of cotton canvas. It can resist various frictions and scratches, improving the puncture resistance of the upper 2. Aramid fabric 8 is a high-performance synthetic fiber with excellent flame retardant properties. Its limiting oxygen index is usually above 28%, making it difficult to ignite in a flame. It can quickly self-extinguish after leaving the fire source and will not produce molten droplets, effectively protecting the wearer from flame damage. At the same time, aramid fabric 8 also has high strength, high modulus, high temperature resistance, chemical corrosion resistance, and good wear resistance. It can withstand a certain degree of friction and stretching without damage. Fiberglass fabric 9 is woven from fiberglass yarn. It is relatively hard and has a certain degree of stiffness, which can effectively block the transfer of flames and heat and has excellent flame retardant properties. The inner lining layer 10 improves the comfort of wearing the shoe. The sole 1 is equipped with a bottom anti-puncture mechanism, which improves the puncture resistance of the sole 1 through its structure.
[0028] Furthermore, such as Figure 2 and Figure 3 As shown, multiple nylon threads 11 are embedded inside the toe bumper 3 to enhance its puncture resistance.
[0029] Furthermore, such as Figure 1 and Figure 2 As shown, multiple reinforcing ribs 12 are provided on the surface of the protective plate 4. By providing multiple reinforcing ribs 12 on the protective plate 4, the support strength of the protective plate 4 is improved, and the user's feet are protected from impact.
[0030] Furthermore, such as Figure 2 As shown, a steel sheet layer 13 is embedded in the support of the toe box 6. The thickness of the steel sheet layer 13 is 2-5 mm. This structure improves the support of the toe box 6 for the heel and enhances the heel's resistance to impact and puncture.
[0031] Furthermore, such as Figure 1 As shown, the Cordura fabric 7 has a hydrophobic coating to improve the water-repellent performance of the shoe upper 2.
[0032] Furthermore, such as Figure 2 As shown, the bottom puncture protection mechanism includes an abrasion-resistant rubber layer 14 set at the bottom of the sole 1, steel plates 15 embedded in the front and back sides of the sole 1, carbon plate 16 and TPU plate 17 embedded in the middle of the sole 1, with the TPU plate 17 located below the carbon plate 16. Through the internal structure of the sole 1, the sole 1 is protected against punctures in sections, and compared with the sole 1 being embedded with a whole steel plate 15, the feel of the shoe is improved.
[0033] Working principle: The structure of the upper layer protection mechanism improves the impact resistance and puncture resistance of the shoe upper 2. The toe impactor 3 can protect the user's toes from impact and puncture. The toe impactor 3 is embedded with multiple nylon threads 11 to enhance its puncture resistance. The protective plate 4 protects the user's instep from impact. The protective plate 4 is provided with multiple reinforcing ribs 12 on its surface to enhance its support strength. The puncture-proof plate 5 can protect the sides of the user's foot from puncture. The support backrest 6 supports the heel of the shoe upper 2. The support backrest 6 is embedded with a steel plate layer 13 to enhance the impact resistance and puncture resistance of the heel.
[0034] Through the structural design of the upper 2, the Cordura fabric 7 can resist various frictions and scratches, improving the puncture resistance of the upper 2. The aramid fabric 8 has excellent flame retardant properties, with a limiting oxygen index usually above 28%. It is difficult to ignite in a flame and can quickly self-extinguish after leaving the fire source without producing molten droplets, effectively protecting the wearer from flame damage. At the same time, the aramid fabric 8 also has high strength, high modulus, high temperature resistance, chemical corrosion resistance and other characteristics. It also has good wear resistance and can withstand a certain degree of friction and stretching without damage. The glass fiber fabric 9 is woven from glass fiber yarn, which can effectively block the transfer of flame and heat and has excellent flame retardant properties.
[0035] The puncture resistance of the sole 1 is improved by the bottom anti-puncture mechanism. Steel plates 15 are embedded in the front and back sides of the sole 1, respectively. Carbon plate 16 and TPU plate 17 are embedded in the middle of the sole 1. The TPU plate 17 is located below the carbon plate 16. Through the internal structure of the sole 1, the sole 1 is protected against punctures in sections.
[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
