DETAILED DESCRIPTION

[0028] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0029] like Figures 1 to 4 As shown, a puncture-proof insulating boot comprises an insulating shoe body 1 and an insulating sole 2 connected to the insulating shoe body 1; the insulating shoe body 1 is made of a high-insulation material to ensure electrical safety. The insulating sole 2 comprises an upper puncture-proof layer 21, an anti-puncture edge layer 22, a lower puncture-proof layer 23 and an elastic reinforcement rib structure 24. The upper puncture-proof layer 21 is adaptively connected to the bottom end surface of the insulating shoe body 1; the upper puncture-proof layer 21 is directly adaptively connected to the bottom end surface of the insulating shoe body 1 and is made of a high-strength, highly wear-resistant hard material. As a puncture-proof line of defense, it can effectively resist direct puncture from most sharp objects. The puncture-proof edge layer 22 is arranged along the edge of the upper puncture-proof layer 21 on the bottom end surface of the upper puncture-proof layer 21; the puncture-proof edge layer 22 is arranged along the edge of the upper puncture-proof layer 21 to form a circle of protective barrier, further enhancing the edge protection capability of the sole and preventing side punctures. The lower puncture-proof layer 23 is consistent in shape and size with the upper puncture-proof layer 21 and is connected to the bottom end surface of the puncture-proof edge layer 22. The lower puncture-proof layer 23 is located at the bottom and is also made of a high-strength, highly wear-resistant hard material. It is tightly connected to the puncture-proof edge layer 22 to form a solid bottom protective layer 3 that can maintain structural integrity even when subjected to strong impact forces. Several elastic reinforcing rib structures 24 are arranged between the upper puncture-proof layer 21 and the lower puncture-proof layer 23. Arranging several elastic reinforcing rib structures 24 between the upper puncture-proof layer 21 and the lower puncture-proof layer 23 not only improves the sole's resistance to bending and twisting, but also has good elasticity and shock absorption effects. It can effectively disperse force when impacted, reduce local stress concentration, and thus enhance the overall puncture-proof effect. It has high practical value and promotion prospects.

[0030] Based on the insulating shoe body 1 and the insulating sole 2, the puncture-proof insulating boots improve the insulating sole 2. By providing an upper puncture-proof layer 21, an anti-puncture edge layer 22, a lower puncture-proof layer 23 and an elastic reinforcement rib structure 24, a good protective structure is formed, which effectively solves the shortcomings of traditional insulating boots in puncture resistance, significantly improves the puncture-proof ability of the boots, and provides more reliable protection for the foot safety of workers in high-risk environments.

[0031] In this embodiment, the elastic reinforcement rib structure 24 includes a reinforcement rib seat 241, a reinforcement rib sliding column 242 and a plastic spring 243; the reinforcement rib seat 241 is connected to the lower anti-puncture layer 23; the reinforcement rib seat 241 has a sliding cavity 2411; the plastic spring 243 is placed in the sliding cavity 2411; the upper end of the reinforcement rib sliding column 242 is connected to the bottom end surface of the upper anti-puncture layer 21; the lower end of the reinforcement rib sliding column 242 can be movably embedded in the sliding cavity 2411 and abut against the top of the plastic spring 243. By providing a reinforcing rib seat 241, a reinforcing rib slide 242, and a plastic spring 243 to form an elastic reinforcing rib structure 24, after the foot wears the puncture-proof insulating boot and the foot force acts on the insulating sole 2, the reinforcing rib slide 242 can move back and forth up and down within the sliding cavity 2411, having a good elastic effect and a good shock-absorbing effect, thereby enhancing the comfort of wearing the puncture-proof insulating boot. At the same time, this design, combined with the upper puncture-proof layer 21 and the lower puncture-proof layer 23, not only improves the bending and twisting resistance of the sole, but also has a good elastic effect and a good shock-absorbing effect, can effectively disperse force when impacted, reduce local stress concentration, and thus enhance the overall puncture-proof effect. Of course, the shape, specifications, and quantity of the reinforcing rib seat 241, the reinforcing rib slide 242, and the plastic spring 243 can be reasonably set according to needs and are not limited to those shown in the embodiment drawings of this application.

[0032] In order to facilitate production and stabilize the structural connection, the upper puncture-proof layer 21 , the puncture-proof edge layer 22 and the reinforcing rib sliding column 242 are integrally formed; the lower puncture-proof layer 23 and the reinforcing rib sliding column 242 are integrally formed.

[0033] Preferably, the upper puncture-proof layer 21, the lower puncture-proof layer 23, the puncture-proof edge layer 22, the rib seat 241, and the rib slide 242 are all made of Kevlar. Using Kevlar to form the upper puncture-proof layer 21, the lower puncture-proof layer 23, the puncture-proof edge layer 22, the rib seat 241, and the rib slide 242 reduces the use of multiple materials, facilitating production and increasing production efficiency. Kevlar also offers high strength, excellent toughness, high-temperature resistance, and excellent insulation, making it easy to process and form. Its strength is five times that of steel of equivalent quality, resulting in excellent puncture-proof performance for the insulating sole 2. Of course, other materials, such as glass fiber and aramid fiber, can also be considered as alternatives to Kevlar. The plastic spring 243 is made of PP. Compared to traditional metal materials, this plastic spring 243 is lightweight, corrosion-resistant, highly elastic, and insulating. It can not only deform quickly and absorb energy when impacted by external force, but also quickly return to its original shape after the impact to maintain the integrity of the structure, so that the elastic reinforcement rib structure 24 has good elasticity.

[0034] In order to improve the anti-slip ability of the anti-puncture insulating boots, anti-slip concave-convex patterns 231 are provided on the front bottom surface of the lower anti-puncture layer 23 .

[0035] In this embodiment, the insulating shoe body 1 includes, from the inside out, a skin-friendly inner layer 11, a Kevlar middle layer 12, and a rubber outer layer 13. By configuring the insulating shoe body 1 in this manner, the skin-friendly inner layer 11 is first of all in direct contact with the wearer's foot. Therefore, its material needs to be both skin-friendly and breathable to ensure comfort when worn. Secondly, the Kevlar middle layer 12 primarily provides additional support and protection to enhance the overall strength and durability of the shoe body, while also providing puncture resistance. At the same time, because Kevlar fiber has excellent electrical insulation properties, it can also improve the insulation effect of the shoe body to a certain extent. Finally, the rubber outer layer 13 primarily isolates electrical hazards from the external environment to ensure the wearer's safety. Furthermore, the rubber outer layer 13 also has certain wear resistance, anti-slip, and weather resistance properties to cope with various complex working environments. The design of the insulating shoe body 1 fully considers the wearer's comfort and safety needs. Through reasonable material selection and structural design, it achieves a perfect balance between electrical insulation, support and protection, and comfortable wearing.

[0036] Preferably, the skin-friendly inner layer 11 is made of a microfiber material; and the rubber outer layer 13 is made of natural rubber. The skin-friendly inner layer 11 is made of a microfiber material, which has excellent softness and comfort, can fit closely to the skin, and provide an unparalleled skin-friendly experience. The fine structure of the microfiber gives the inner layer excellent air permeability and moisture absorption, effectively keeping the skin dry, reducing friction and discomfort. Secondly, the rubber outer layer 13 is made of natural rubber, which has excellent elasticity and wear resistance, as well as insulation, anti-electrical and waterproof functions. The unique physical properties of natural rubber enable the outer layer to fit closely to various surfaces, providing long-lasting protection.

[0037] To improve the puncture resistance of the insulating shoe body 1, the thickness of the Kevlar intermediate layer 12 is greater than that of the rubber outer layer 13 and greater than that of the skin-friendly inner layer 11. By limiting the thickness of the Kevlar intermediate layer 12, the strength of the insulating shoe body 1 is enhanced, more effectively resisting external forces, ensuring product integrity and safety, and improving the puncture resistance of the insulating shoe body 1.

[0038] In order to further enhance the strength of the insulating shoe body 1 , better protect the soles and toes, and achieve a puncture-proof effect, a PVC protective layer 3 is provided on the outer surface of the upper end of the insulating shoe body 1 corresponding to the front end position of the insulating sole 2 .

[0039] In summary, the embodiment of the present invention provides a puncture-proof insulating boot, wherein the puncture-proof insulating boot has the following advantages:

[0040] 1. Based on the insulating shoe body 1 and the insulating sole 2, the insulating sole 2 is improved by providing an upper anti-puncture layer 21, an anti-puncture edge layer 22, a lower anti-puncture layer 23 and an elastic reinforcement structure 24 to form a good protective structure, which effectively solves the shortcomings of traditional insulating boots in terms of puncture resistance, significantly improves the puncture resistance of the boots, and provides more reliable protection for the foot safety of workers in high-risk environments.

[0041] Second, a plurality of elastic reinforcing rib structures 24 are arranged between the upper anti-puncture layer 21 and the lower anti-puncture layer 23. On the one hand, they not only improve the anti-bending and anti-twisting capabilities of the sole, but also have good elasticity and shock absorption effects. They can effectively disperse force when impacted and reduce local stress concentration, thereby enhancing the overall anti-puncture effect. This has high practical value and promotion prospects.

[0042] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present application. These improvements and replacements should also be regarded as the scope of protection of the present application.
