Description

Technical Field

[0001] This utility model relates to the field of heat-insulating shoe technology, specifically to a front and rear protective heat-insulating shoe. Background Technology

[0002] Safety shoes are a general term encompassing both safety and protective footwear. They typically refer to footwear worn in various work environments to protect the feet and legs from foreseeable injuries. In fields such as highways, metallurgy, casting, thermal engineering, and fire rescue, workers often need to walk on high-temperature surfaces for short periods. In such situations, ordinary work shoes are insufficient to withstand high temperatures, leading to adverse consequences such as sole damage and foot burns. However, some existing high-temperature resistant and heat-insulating safety shoes have relatively simple structures and functions, resulting in limited protection and poor protection at the front and rear. For example, during fire rescue or hazardous operations in high-temperature environments, if the front or rear of the heat-insulating shoe is bumped or struck during movement, causing significant deformation or even breakage, the shoe's heat insulation performance can be reduced, potentially leading to injuries to workers and foot injuries. Utility Model Content

[0008] Preferably, multiple sets of reinforcing plates are fixedly connected at equal intervals around the outer and inner sides of the upper surface of the substrate, and the adjacent reinforcing plates on the outer and inner sides of the upper surface of the substrate are staggered. The reinforcing plates have a long strip structure, and the end face of the reinforcing plates has a fan-shaped ring structure. Furthermore, puncture-resistant fabric is fixedly connected between the outer reinforcing plate and the inner reinforcing plate.

[0009] Preferably, the shoe upper is composed of a heat-insulating lining and a fireproof cloth. The heat-insulating lining is fixedly connected to the inside of the fireproof cloth, while the front protective layer and the rear protective layer are fixedly connected to the outside of the fireproof cloth.

The sole 1 is composed of a flame-retardant layer 2, a heat-insulating layer 3, a puncture-resistant plate layer 4, a cushioning layer 5, and a puncture-resistant mesh layer 6. A front anti-slip layer 7 and a rear anti-slip layer 16 are fixedly connected to the lower surface of the flame-retardant layer 2, respectively. The heat-insulating layer 3 is fixedly connected to the upper surface of the flame-retardant layer 2, and a puncture-resistant plate layer 4 is fixedly connected to the upper surface of the heat-insulating layer 3. Layer 4 is fixedly connected to the stab-resistant mesh layer 6 via the buffer layer 5. At the same time, the main transverse rib 11 is fixedly connected to the front protective layer 13. The main vertical rib 14 and the secondary vertical rib 15 are fixedly connected to the upper surface of the main transverse rib 11, and the secondary transverse rib 12 is fixedly connected to the surface of the main vertical rib 14.

The surface of the reinforcing plate 18 is fixedly connected to the stab-resistant fabric 19. The upper end of the rear protective layer 20 is fixedly connected to the rear end surface of the shoe upper 8.

[0019] In this embodiment, when a user wears these heat-insulating shoes for fire rescue or other high-temperature environments, the front anti-slip layer 7 and the rear anti-slip layer 16 enhance the anti-slip effect of the shoes. The combination of the heat insulation layer 3, the puncture-resistant plate layer 4, the cushioning layer 5, and the puncture-resistant mesh layer 6 effectively enhances the heat insulation and anti-puncture effect of the sole 1, ensuring the user's safety while walking. Furthermore, the frame structure within the front protective layer 13, composed of main transverse ribs 11, secondary transverse ribs 12, main vertical ribs 14, and secondary vertical ribs 15, helps to reduce the front anti-slip effect. The weight of the protective layer 13 helps to enhance the overall structural strength of the front protective layer 13, increase the resistance of the front of the heat-insulating shoe to impacts from external objects, reduce the probability of deformation and damage to the front of the heat-insulating shoe, and also reduce the probability of accidental injury to the user's toes. The base plate 17, reinforcing plate 18 and puncture-resistant fabric 19 provided in the rear protective layer 20 can not only enhance the impact protection effect of the rear of the heat-insulating shoe, but also help to enhance the puncture resistance effect, ensure the safety of the user's feet when walking, and also help to reduce the probability of the heat-insulating shoe being damaged due to accidental impacts.

[0020] In a preferred embodiment, the front protective layer 13 has a curved structure, and the cross-section of the front protective layer 13 has an L-shaped structure. The cross-sections of the main horizontal rib 11, secondary horizontal rib 12, main vertical rib 14 and secondary vertical rib 15 fixedly connected within the front protective layer 13 are all cylindrical.

[0021] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The main transverse rib 11, secondary transverse rib 12, main vertical rib 14 and secondary vertical rib 15 provided in the front protective layer 13 can help enhance the overall structural strength of the front protective layer 13, reduce the probability of the front protective layer 13 being deformed due to the impact of external objects, and thus help enhance the protective effect of the heat-insulating shoe on the user's toes. At the same time, the front protective layer 13 can be made of flame-retardant and wear-resistant rubber material.

[0022] In a preferred embodiment, the main horizontal rib 11 has a U-shaped structure, while the main vertical rib 14 and the secondary vertical rib 15, which are fixedly connected to both ends of the main horizontal rib 11, both have a U-shaped structure. Furthermore, multiple sets of secondary horizontal ribs 12 are fixedly connected at equal intervals on the side of the main vertical rib 14 away from the secondary vertical rib 15, and the multiple sets of secondary horizontal ribs 12 all have a fan-shaped ring structure.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The main horizontal rib 11, secondary horizontal rib 12, main vertical rib 14 and secondary vertical rib 15 can effectively enhance the protective effect of the front end of the heat-insulating shoe, and can also play a corresponding shaping effect on the front end of the heat-insulating shoe, reducing the probability of the front end of the heat-insulating shoe being accidentally deformed and damaged due to impact from external objects.

[0024] In a preferred embodiment, the rear protective layer 20 has a fan-shaped annular structure, and the two sets of substrates 17 fixedly connected within the rear protective layer 20 both have fan-shaped annular structures. The sides of the substrates 17 are symmetrically provided with fitting grooves, which are elongated. The end face formed by the substrates 17 and the fitting grooves together has an I-shaped structure.

[0025] In this embodiment, as Figure 1 and Figure 5 The rear protective layer 20 can be made of flame-retardant and wear-resistant rubber material, and the fitting grooves on both sides of the substrate 17 can help enhance the stability of the substrate 17 fixedly connected inside the rear protective layer 20.

[0026] In a preferred embodiment, multiple sets of reinforcing plates 18 are fixedly connected around the outer and inner sides of the upper surface of the substrate 17 at equal intervals along the circumference. The adjacent reinforcing plates 18 on the outer and inner sides of the upper surface of the substrate 17 are staggered. The reinforcing plates 18 have a long strip structure, and the end face of the reinforcing plate 18 has a fan-shaped annular structure. Furthermore, puncture-resistant fabric 19 is fixedly connected between the outer reinforcing plate 18 and the inner reinforcing plate 18.

[0027] In this embodiment, as Figure 1 , Figure 3 , Figure 4 and Figure 5 The staggered distribution of the reinforcing plates 18 can reduce the number of reinforcing plates 18, reduce the overall weight of the rear protective layer 20, and also help enhance the overall structural strength and protective effect of the rear protective layer 20. Furthermore, the combination of the reinforcing plates 18 and the puncture-resistant fabric 19 can further enhance the puncture resistance of the rear protective layer 20, effectively protecting the user's feet.

[0028] In a preferred embodiment, the upper 8 is composed of a heat-insulating liner 9 and a fireproof cloth 10. The heat-insulating liner 9 is fixedly connected to the inside of the fireproof cloth 10, while the outer side of the fireproof cloth 10 is fixedly connected to the front protective layer 13 and the rear protective layer 20, respectively. The lower end of the front protective layer 13 is fixedly connected to the front anti-slip layer 7, and the lower end of the rear protective layer 20 is fixedly connected to the rear anti-slip layer 16.

[0029] In this embodiment, as Figure 1 and Figure 3 The fireproof cloth 10 can be made of basalt fiber, while the heat insulation lining 9 can help enhance the overall heat insulation effect of the shoe upper 8. At the same time, the upper and lower ends of the front protective layer 13 and the rear protective layer 20 are fixedly connected to the sole 1 and the shoe upper 8 respectively, thereby helping to enhance the stability of the connection between the various parts of the heat-insulating shoe.

[0030] As a preferred embodiment, the flame-retardant layer 2, the front anti-slip layer 7 and the rear anti-slip layer 16 are all made of flame-retardant and wear-resistant rubber, while the anti-stab plate layer 4 is made of TPU, the buffer layer 5 is made of EVA, and the anti-stab mesh layer 6 is made of Kevlar fiber. At the same time, the front anti-slip layer 7 and the rear anti-slip layer 16, which are fixedly connected to the lower surface of the flame-retardant layer 2, are both square structures with anti-slip stripes on their surfaces.

[0031] In this embodiment, as Figure 1 The puncture-resistant plate layer 4 is made of TPU material, which has good puncture resistance and abrasion resistance, as well as high bending strength. This not only enhances the puncture resistance but also makes it easy for users to wear and walk. Meanwhile, the cushioning layer 5 is made of EVA material, which has excellent elasticity and improves the user's comfort when wearing it. The puncture-resistant mesh layer 6 is made of Kevlar fiber material, which can further enhance the puncture resistance. Therefore, the sole 1, through the combination of multiple protective structures, can effectively enhance the overall protective effect of the heat-insulating shoe.
