Fire-fighting shoes with corrosion-resistant function

Abstract

This utility model relates to the field of fire-fighting shoes, specifically a fire-fighting shoe with corrosion resistance. It includes a fire-fighting boot body, the outer layer of which is covered with several detachable additional layers on the front. Each additional layer includes a separable forefoot and boot shaft, the dimensions of which are adapted to the outer dimensions of the fire-fighting boot body. An embedded slot is provided at the junction of the forefoot and boot shaft. In this utility model, the additional layers serve as an external protective layer for the fire-fighting boot body, further enhancing its corrosion resistance on top of the original corrosion resistance.

Description

Technical Field

[0001] This utility model relates to the field of fire-fighting shoes, specifically a fire-fighting shoe with corrosion resistance. Background Technology

[0002] Fire boots are protective footwear specifically designed for firefighters and rescue personnel. They are made of fire-resistant nitrile rubber or composite flame-retardant rubber, offering excellent protection against high temperatures, heat flow, and flames. The upper can withstand a heat flow of 2W / cm² for three minutes. The fire-resistant upper provides excellent protection against common chemicals: fuels, greases, solvents, and weak acids with a maximum pressure resistance of 500 volts. They are also impact-resistant, puncture-resistant, anti-static, have a wear-resistant sole, and a cut-resistant upper.

[0003] The core protective function of firefighter shoes relies heavily on the outer layer material. If the outer corrosion-resistant layer cracks, hardens, loses elasticity, or has increased porosity due to ultraviolet radiation, chemical erosion, or mechanical wear, its physical barrier function will be destroyed. This can lead to external corrosive substances potentially corroding the sole, lining, and other structures, or causing the loss of waterproof function, directly affecting the safety of firefighters' feet.

[0004] Firefighter boots are mostly made of high-molecular polymers, and their aging is an irreversible process. These changes cannot be restored by simple repairs. Firefighter boots are frequently exposed to corrosive media in common firefighting scenarios during each mission, such as acids / alkalis / salts in sewage, oils, chemical reagents, and residual corrosive substances after firefighting. Especially in high-temperature environments, the outer layer of firefighter boots is prone to rapid aging. Most commercially available firefighter boots are one-piece designs, and firefighter boots with only the outer layer aged and damaged need to be scrapped entirely for safety reasons. To enhance the corrosion resistance and durability of firefighter boots and extend their service life, we have proposed a firefighter boot with corrosion resistance. Utility Model Content

[0005] The purpose of this invention is to provide a fire-fighting shoe with corrosion resistance to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a fire boot with corrosion resistance is provided, comprising a fire boot body, wherein the outer layer of the fire boot body is covered with several detachable additional layers on the front, the additional layers comprising a separable boot front and a boot shaft, the dimensions of the boot front and the boot shaft being adapted to the outer dimensions of the fire boot body, and an embedded slot being provided at the junction between the boot front and the boot shaft.

[0007] Furthermore: both the outer surface of the fire boot body and the outer surface of the outer additional layer are provided with positioning protrusions, and the inner surface of the outer additional layer is provided with positioning grooves that are adapted to the size of the positioning protrusions.

[0008] Furthermore: the surface of the outer additional layer has through holes on opposite sides of the fire boot body, and the outer wall of the fire boot body has a positioning rod at the through hole position, with a positioning ball threaded to one end of the positioning rod.

[0009] Furthermore, the corners of the front part of the boot and the boot shaft are both rounded.

[0010] Furthermore: at the junction of the boot front and the boot shaft, the corner of the boot shaft covers the outer side.

[0011] Furthermore, the diameter of the positioning ball is not less than the diameter of the through hole.

[0012] Furthermore, both the outer additional layer and the outer surface of the positioning ball are smooth surfaces.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, the outer additional layer serves as an external protective layer for the fire boot body. Building upon the original corrosion-resistant function of the fire boot body, it further enhances its corrosion resistance. Since the front of the fire boot, especially the toe and outer side of the shoe, is in direct contact with the ground and potentially corrosive liquids and is subjected to frequent mechanical damage, it is the area with the highest risk of corrosion. Therefore, the outer additional layer is detachably installed on the outer front of the fire boot body and can be replaced after corrosion, enhancing the corrosion resistance and durability of the fire boot and helping to ensure that the service life of the fire boot reaches the expected value, making it more environmentally friendly.

[0016] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-2The figure shows a preferred embodiment of the present invention, a fire boot with corrosion resistance, including a fire boot body 1. The outer layer of the fire boot body 1 is covered with several detachable additional layers 2 on the front. The additional layers 2 include a separable boot front part 3 and boot shaft part 4. The dimensions of the boot front part 3 and boot shaft part 4 are adapted to the outer dimensions of the fire boot body 1. An embedded groove is provided at the junction between the boot front part 3 and boot shaft part 4 to prevent corrosive substances from seeping in from the edge. The front of the fire boot, especially the toe and the outer side of the shoe body, is the area with the highest risk of corrosion because it is in direct contact with the ground and potentially corrosive liquids and is subjected to high frequency of mechanical damage. Therefore, the additional layers 2 are provided on the outer front of the fire boot body 1.

[0018] Specifically, the outer surfaces of both the fire boot body 1 and the outer additional layer 2 are provided with positioning protrusions 5, and the inner surfaces of the outer additional layer 2 are provided with positioning grooves 6 that are adapted to the size of the positioning protrusions 5. The positioning protrusions 5 and positioning grooves 6 are mainly provided to facilitate the positioning of the outer additional layer 2 during quick disassembly, and can also assist in the stable connection between several outer additional layers 2.

[0019] Among them, the surface of the outer additional layer 2 is provided with through holes 7 on the opposite sides of the fire boot body 1. The outer wall of the fire boot body 1 is provided with a positioning rod 8 at the through hole 7. One end of the positioning rod 8 is threadedly connected to a positioning ball 9. The positioning rod 8 and the fire boot body 1 can be integrally formed or glued to the fire boot body 1. The positioning ball 9 can tightly fix the outer additional layer 2 to the outside of the fire boot body 1.

[0020] Understandably, the corners of the front part 3 and the boot shaft part 4 are rounded to reduce stress concentration and avoid adverse effects from long-term bending.

[0021] Since the boot shaft 4 is located on the upper side, the corrosive liquid will flow from top to bottom according to the gravitational potential energy. Therefore, the corner of the boot shaft 4 at the junction of the boot front 3 and the boot shaft 4 is covered on the outside.

[0022] To ensure that the positioning ball 9 can fix the outer additional layer 2, the diameter of the positioning ball 9 is not less than the diameter of the through hole 7. It should also be noted that the size of the positioning ball 9 is only slightly larger than the size of the through hole 7. The outer additional layer 2 is preferably made of fluororubber, butyl rubber, polyether polyurethane or fluoropolymer that is resistant to strong acids and alkalis. Due to the influence of the material and thickness of the outer additional layer 2, the outer additional layer 2 has a certain degree of elasticity or extensibility. When necessary, the outer layer 2 can be torn off from the outside of the fire boot body 1 to prevent the corroded outer additional layer 2 from carrying corrosive substances to remain on the inner side of the outer additional layer 2. In non-emergency situations, under normal circumstances, the outer layer 2 should be replaced from the surface of the fire boot body 1 after the positioning ball 9 is removed.

[0023] Understandably, the outer surfaces of the outer additional layer 2 and the positioning ball 9 are smooth surfaces to prevent corrosive liquids from remaining.

[0024] In this embodiment, during installation, the positioning protrusions 5 and positioning grooves 6 facilitate the positioning of the outer additional layer 2 during quick disassembly and also assist in the connection between several outer additional layers 2. After several outer additional layers 2 are attached and tightened, the positioning ball 9 can be screwed onto the positioning rod 8 to firmly fix the outer additional layer 2 to the outside of the fire boot body 1. The outer additional layer 2 serves as an external protective layer for the fire boot body 1, further enhancing the corrosion resistance of the fire boot body 1 on the basis of its original corrosion resistance function. Since the front of the fire boot, especially the toe and the outer side of the shoe, is in direct contact with the ground and potentially corrosive liquids and is subjected to high-frequency mechanical damage, it is the area with the highest risk of corrosion. Therefore, the outer additional layer 2 is located on the outer front of the fire boot body 1.
