Description

Technical Field

[0001] This utility model relates to the field of fire suit accessories technology, specifically a non-drip fire suit anti-slip hook and loop fastener. Background Technology

[0002] Firefighting suits are crucial protective equipment for firefighters during missions, and their safety is paramount. Hook and loop fasteners, as key components of firefighting suits used to connect and secure various parts, need to possess several special properties. However, existing firefighting suits are mostly made of synthetic fibers such as polyester and nylon. While lightweight, these fibers can produce molten droplets during combustion, accelerating flame spread and increasing the size of the fire. If molten material adheres to the skin, it can cause burns, and removing the molten material can easily tear the skin, resulting in extensive burns. Furthermore, the simple structure of existing firefighting suit hook and loop fasteners makes them prone to detachment during use, posing a safety hazard. To address these shortcomings, existing technology (Chinese patent application number: 202220546350.8, authorized announcement date: 2022-07-26) discloses a drip-free hook and loop fastener for firefighting suits. By installing a protective layer, it solves the problem of dripping fasteners found in most existing firefighting suits. Made of synthetic fibers such as polyester and nylon, these materials, though lightweight, produce molten droplets during combustion, accelerating flame spread and increasing the size of the fire. If the molten material adheres to the skin, it can cause burns, and removing the molten material can easily tear the skin, resulting in extensive burns. The installation of a protective layer enables high-temperature resistant, flame-retardant protective clothing, reducing molten droplets, slowing flame spread and fire expansion, and minimizing burns and skin damage. The hook-and-loop fasteners on this fire-fighting suit, through a combination of sub-attachments, female attachments, fasteners, and retaining rings, solve the problem of existing fire-fighting suit hook-and-loop structures being simple and prone to detachment during use, posing a safety hazard. The combination of sub-attachments, female attachments, fasteners, and retaining rings strengthens the existing hook-and-loop structure, ensuring a secure bond and preventing easy detachment, thus guaranteeing the normal use of the fire-fighting suit.

[0003] Existing technology solves the problem of simple hook and loop fasteners on fire suits being prone to falling off during use by using a combination of sub-attachments, female-attachments, fasteners, and fastening rings. However, when ordinary sub-attachments and female-attachments are fastened together, the barbs on the sub-attachments cannot be fully embedded into the fiber gaps of the female-attachments, resulting in poor adhesion and causing the hook and loop fasteners to easily loosen due to external force. At the same time, the sub-attachments and female-attachments are prone to deformation or displacement during use. Therefore, we have proposed a drip-free fire suit anti-fall hook and loop fastener that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a non-drip fire suit anti-slip hook and loop fastener to solve the problems mentioned in the background art, where when the sub-attachment and the female-attachment are fastened together, the barbs on the sub-attachment cannot be fully embedded into the fiber gaps of the female-attachment, resulting in poor adhesion and causing the hook and loop fastener to easily loosen due to external force. At the same time, the sub-attachment and the female-attachment are prone to deformation or displacement during use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-drip fire-fighting suit anti-slip hook and loop fastener, comprising a hook and loop fastener body and an adjusting buckle, wherein a hook surface layer is connected to the upper left end of the hook and loop fastener body, and a textured surface layer is provided at the lower right end of the hook and loop fastener body, and the hook and loop fastener body passes through the interior of the adjusting buckle; further comprising: anti-slip hooks are provided at equal intervals at the top edge of the hook surface layer, and limiting holes are provided at equal intervals at the bottom edge of the textured surface layer; a reinforcing layer is bonded between the hook surface layer and the textured surface layer and the hook and loop fastener body; protective blocks are provided on the outer sides of both ends of the hook and loop fastener body; and a fire-retardant coating is applied to the surface of the hook and loop fastener body.

[0006] Preferably, the hook and loop fastener body is made of aramid fiber fabric, the hook surface layer and the loop surface layer are bonded together, the anti-detachment hooks and the limiting holes are positioned one-to-one, the ends of the anti-detachment hooks are shaped like "mushroom heads", the diameter of the anti-detachment hooks is 0.15 mm, and the anti-detachment hooks and the limiting holes are connected by an interlocking mechanism.

[0007] Preferably, the reinforcing layer is made of high-strength polyester mesh material, and the reinforcing layer can improve the overall strength and stability of the hook and loop fastener body.

[0008] Preferably, the fire-retardant coating is applied to the outer surface of the hook and loop fastener body, and the thickness of the fire-retardant coating is 0.05 mm. An antistatic coating is applied to the side of the fire-retardant coating away from the hook and loop fastener body, and the thickness of the antistatic coating is 0.03 mm.

[0009] Preferably, a fixing ring is fitted on the outer side of one end of the hook and loop fastener body, and the fixing ring can enhance the fixing effect of the hook and loop fastener body.

[0010] Preferably, the outer layer of the hook and loop fastener body is heat-pressed with a protective layer, and the protective layer is made of fiberglass fabric.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the anti-slip hook and loop fastener of the drip-free fire suit adopts a novel structural design, the specific details of which are as follows:

[0012] (1) A small anti-detachment barb is set on the edge of the hook surface layer of the hook and loop fastener body, so that when the hook and loop fastener bodies are fastened together, these anti-detachment barbs will be embedded in the limiting holes of the surface layer, forming additional resistance and preventing the hook and loop fastener bodies from being easily loosened by external force; furthermore, through the setting of the fixing ring, it can be put on the fixing buckle of the fire suit, further enhancing the fixing effect of the hook and loop fastener body.

[0013] (2) The use of high-temperature resistant and non-drip aramid fiber fabric and specially treated hook and loop fastener structural material ensures that the hook and loop fastener body will not melt and drip in high-temperature fire environment, greatly reducing the risk of firefighters being burned by molten droplets and providing reliable high-temperature protection for firefighters.

[0014] (3) A high-strength mesh reinforcement layer is added between the hook and loop layer and the loop layer. This reinforcement layer is woven from high-strength glass fiber or carbon fiber. The reinforcement layer can effectively disperse the external force on the hook and loop tape, enhance the overall strength of the hook and loop tape, and prevent it from breaking or falling off when it is pulled.

[0015] (4) The fire-retardant coating can decompose to produce non-combustible gas when exposed to high temperature or flame, which can isolate oxygen, prevent the spread of flame, protect the hook and loop fastener body and other parts of the fire suit from flame damage, and reduce the resistance of the hook and loop fastener body surface, accelerate the charge dissipation speed, prevent static electricity accumulation, and avoid the danger caused by static electricity sparks.

[0022] 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.

[0023] Please see Figures 1-5 This utility model provides the following technical solution: a non-drip fire suit anti-slip hook and loop fastener;

[0024] Example 1: To address the problem in existing technologies where, when the female and male adhesive strips are interlocked, the barbs on the female adhesive strip cannot be fully embedded into the fiber gaps of the male adhesive strip, resulting in poor adhesion and easy loosening of the hook and loop fastener due to external force, and the tendency for the female and male adhesive strips to deform or shift during use, the following solution is disclosed. Please refer to the following for details. Figures 1-3 As shown, the device includes a hook and loop fastener body 1 and an adjusting buckle 3. A hook surface layer 2 is connected to the upper left end of the hook and loop fastener body 1, and a loop surface layer 4 is located on the lower right end of the hook and loop fastener body 1. The hook and loop fastener body 1 passes through the interior of the adjusting buckle 3. It also includes: anti-slip hooks 7 evenly spaced at the top edge of the hook surface layer 2, and limit holes 8 evenly spaced at the bottom edge of the loop surface layer 4. The hook and loop fastener body 1 is made of aramid fiber fabric, and the hook surface layer 2 and the loop surface layer 4 are bonded together. The anti-slip hooks 7 and the limit holes 8 are positioned one-to-one. Furthermore, the end of the anti-slip hook 7 is set in a "mushroom head" shape, and the diameter of the anti-slip hook 7 is 0.15MM. The anti-slip hook 7 and the limiting hole 8 are connected by an insertion. The hook surface layer 2 and the rough surface layer 4 are bonded to the hook and loop fastener body 1 with a reinforcing layer 9. The reinforcing layer 9 is made of high-strength polyester mesh material. The reinforcing layer 9 can improve the overall strength and stability of the hook and loop fastener body 1. Protective blocks 5 are fitted on the outer sides of both ends of the hook and loop fastener body 1. The surface of the hook and loop fastener body 1 is connected with a fire-retardant coating 10.

[0025] When wearing the fire suit, align the parts that need to be connected, then press the hook-and-loop fastener body 1 (hook and loop layer 2 and loop layer 4) together firmly to ensure a tight connection. This ensures the fastener connection is secure and will not come loose accidentally during firefighting operations. Because a ring of tiny anti-loosening hooks 7 is provided around the edge of the hook and loop layer 2 of the fastener body 1, these hooks 7 will embed into the limiting holes 8 of the loop layer 4 when the fastener bodies 1 are fastened together, creating additional resistance and preventing the fastener bodies 1 from easily coming loose due to external force. The adjustable buckle 3 ensures the fastener is at a moderate tightness, neither too tight to affect blood circulation and mobility, nor too loose to cause the fire suit to shake or fall off during operations. The suit is made of high-temperature resistant, non-drip aramid fiber fabric and features a specially treated fastener structure. The material ensures that the hook and loop fastener body 1 will not melt and drip in high-temperature fire environments, greatly reducing the risk of firefighters being burned by molten drips and providing reliable high-temperature protection for firefighters. Furthermore, a high-strength mesh reinforcement layer 9 is added between the hook and loop fastener body 1 and the hook surface layer 2 and the textured surface layer 4. This reinforcement layer 9 is woven from high-strength glass fiber or carbon fiber. The reinforcement layer 9 can effectively disperse the external force on the hook and loop fastener body 1, enhance the overall strength of the hook and loop fastener body 1, and prevent breakage or detachment when pulled. In the process of fire rescue, firefighters need to move, climb, and crawl frequently. The protective blocks 5 set at both ends of the hook and loop fastener body 1 can prevent its sharp edges from scratching the firefighters' skin or snagging on other equipment or objects, affecting rescue operations or even causing accidental injuries.

[0026] Example 2: Unlike Example 1, this example utilizes a fixing ring 6 to enhance the fixing effect of the hook and loop fastener body 1. See details... Figure 2 , Figure 4 and Figure 5 As shown, a fixing ring 6 is fitted on the outer side of one end of the hook and loop fastener body 1, and the fixing ring 6 can enhance the fixing effect of the hook and loop fastener body 1. The outer layer of the hook and loop fastener body 1 is heat-pressed with a protective layer 12, and the protective layer 12 is made of fiberglass fabric.

[0027] The fixed ring 6 can be placed on the fastener of the fire suit to further enhance the fixing effect of the hook and loop fastener body 1. The protective layer 12 is non-flammable and high temperature resistant, and can withstand high temperatures without melting or burning. It can effectively block heat transfer. At the same time, it also has good chemical stability and is resistant to corrosion by acids, alkalis and other chemicals, so that the hook and loop fastener body 1 can adapt to complex fire scene environments.

[0028] Example 3: Unlike Example 2, this example utilizes a fire-retardant coating 10 to protect the hook and loop fastener body 1 and other parts of the fire suit from flame damage. See details... Figure 4 and Figure 5 As shown, a fire-retardant coating 10 is applied to the outer surface of the hook and loop fastener body 1, and the thickness of the fire-retardant coating 10 is 0.05 mm. An antistatic coating 11 is applied to the side of the fire-retardant coating 10 away from the hook and loop fastener body 1, and the thickness of the antistatic coating 11 is 0.03 mm.

[0029] The fire-retardant coating 10 can decompose to produce non-combustible gas when exposed to high temperatures or flames, thus isolating oxygen, preventing the spread of flames, and protecting the hook and loop fastener body 1 and other parts of the fire suit from flame damage. The antistatic coating 11 reduces the surface resistance of the hook and loop fastener body 1, accelerates the dissipation of charge, prevents static electricity accumulation, and avoids the danger caused by sparks generated by static electricity.
