Description

Technical Field

[0001] This utility model relates to the technical field of hook and loop fasteners, specifically a flame-retardant and breathable hook and loop fastener with a tightening structure. Background Technology

[0002] Hook and loop fasteners, also known as Velcro or Velcro, are a common fastening accessory used in clothing. They have two sides: one side is made of fine, soft fibers with rounded fibers, and the other side is made of stiffer, hooked fibers.

[0003] For example, a flame-retardant and breathable hook and loop fastener with authorization announcement number "CN222178933U" solves the problem that traditional hook and loop fasteners are flammable, thus leaving room for further improvement in flame-retardant performance. The aforementioned method uses a first substrate layer, one side of which has a flame-retardant layer to enhance the flame-retardant performance of the sub-tape. The other side of the sub-tape has a first waterproof and breathable layer, and the other side of the flame-retardant layer has a second waterproof and breathable layer. Both the first and second waterproof and breathable layers are made of polypropylene fiber material, ensuring sufficient waterproof and breathable performance. Considering existing flame-retardant and breathable hook and loop fasteners, where the polypropylene fiber is woven into the fastener, the fabric on the surface of the fastener is still exposed. When exposed to a fire source, the threads in the fastener will burn, resulting in a shorter flame-retardant time. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing flame-retardant and breathable hook and loop fasteners suffer from burnt threads when exposed to a fire source, resulting in a short flame-retardant time. The invention proposes a flame-retardant and breathable hook and loop fastener with a tightening structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a flame-retardant and breathable hook and loop fastener with a tightening structure, comprising a sub-tape and a mother tape, wherein the lower end of the sub-tape is adhered to the mother tape, the outer wall of the sub-tape is fixedly connected to a first adhesive layer, the outer wall of the mother tape is fixedly connected to a second adhesive layer, and a flame-retardant mechanism is connected to the outer wall of the first adhesive layer.

[0006] Preferably, the flame-retardant mechanism includes an upper outer cover, the inner wall of which is fixedly connected to a first adhesive layer, the outer wall of which is fixedly connected to a first connecting strip, the lower end of which is fixedly connected to a square strip, and the inner wall of the first connecting strip is machined with a first threading hole.

[0007] Preferably, the inner wall of the outer cover is provided with ventilation openings, and the outer wall of the square strip is connected to a docking mechanism.

[0008] Preferably, the docking mechanism includes a square recessed strip, the inner wall of which abuts against a square strip, the outer wall of which is fixedly connected to the lower outer cover, and the outer wall of the lower outer cover is fixedly connected to the second connecting strip.

[0009] Preferably, the inner wall of the lower outer cover is fixedly connected to the second adhesive layer.

[0010] Preferably, the outer wall of the second connecting strip is machined with a second threading hole.

[0011] The present invention proposes a flame-retardant and breathable hook and loop fastener with a tightening structure. The advantages are as follows: the square strips on both sides of the upper outer cover are inserted into the square recessed strips, so that the outer sides of the sub-tape and the main tape are sealed. When facing high-temperature flames, the first connecting strip, the second connecting strip, the upper outer cover and the lower outer cover made of polypropylene isolate the flames, preventing the sub-tape and the main tape from directly contacting the fire source, thereby improving the flame retardant time and service life.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] Please see Figure 1-6In this embodiment, a flame-retardant and breathable hook and loop fastener with a tightening structure includes a sub-belt 1 and a mother belt 2. The lower end of the sub-belt 1 is bonded to the mother belt 2. The outer wall of the sub-belt 1 is fixedly connected to the first adhesive layer 3. The outer wall of the mother belt 2 is fixedly connected to the second adhesive layer 4. A flame-retardant mechanism 5 is connected to the outer wall of the first adhesive layer 3.

[0021] The flame-retardant mechanism 5 includes an upper outer cover 501, which isolates flames through a first connecting strip 502, a second connecting strip 703, an upper outer cover 501, and a lower outer cover 702 made of polypropylene, preventing the sub-belt 1 and the mother belt 2 from directly contacting the fire source. The inner wall of the upper outer cover 501 is fixedly connected to the first adhesive layer 3, the outer wall of the upper outer cover 501 is fixedly connected to the first connecting strip 502, and the lower end of the upper outer cover 501 is fixedly connected to the square strip 503. The inner wall of the first connecting strip 502 is machined with a first threading hole 504.

[0022] The square strips 503 on both sides of the upper outer cover 501 are inserted into the square recessed strips 701, so that the outer sides of the sub-belt 1 and the mother belt 2 are sealed. When facing high-temperature flames, the first connecting strip 502, the second connecting strip 703, the upper outer cover 501 and the lower outer cover 702, made of polypropylene, isolate the flame, prevent the sub-belt 1 and the mother belt 2 from directly contacting the fire source, and improve the flame retardant time and service life.

[0023] The inner wall of the outer cover 501 is processed with a vent 6, and the outer wall of the square strip 503 is connected with a docking mechanism 7. The hook and the rough surface on the sub-strip 1 inside the upper outer cover 501 and the mother strip 2 inside the lower outer cover 702 are brought close to each other and adhered. At the same time, the square strips 503 on both sides of the upper outer cover 501 will be inserted into the square recessed strip 701 to form a docking effect. The docking mechanism 7 includes the square recessed strip 701. The inner wall of the square recessed strip 701 is pressed against the square strip 503. The outer wall of the square recessed strip 701 is fixedly connected to the lower outer cover 702. The outer wall of the lower outer cover 702 is fixedly connected to the second connecting strip 703. The inner wall of the lower outer cover 702 is fixedly connected to the second adhesive layer 4. The outer wall of the second connecting strip 703 is processed with a second thread hole 8.

[0024] Working principle:

[0025] The first adhesive layer 3 on the outer wall of the sub-belt 1 is attached to the inside of the upper outer cover 501, thus fixing the sub-belt 1 to the inside of the upper outer cover 501. The second adhesive layer 4 on the mother belt 2 is attached to the inside of the lower outer cover 702, thus fixing the mother belt 2 to the inside of the lower outer cover 702. The outer yarn is passed through the first thread hole 504 on the first connecting strip 502 and other garments for sewing and fixing. Similarly, the outer yarn is passed through the second thread hole 8 on the second connecting strip 703 and other garments for sewing and fixing on the other side, thus fixing the upper outer cover 501 and the lower outer cover 702 to the garments.

[0026] When it is necessary to continue sealing the opening of the garment, press the outer sides of the upper outer cover 501 and the lower outer cover 702 with both hands to bring the hook and loop sides of the sub-tape 1 inside the upper outer cover 501 and the mother tape 2 inside the lower outer cover 702 closer together and stick them together. At the same time, the square strips 503 on both sides of the upper outer cover 501 will insert into the square recessed strips 701, so that the outer sides of the sub-tape 1 and the mother tape 2 are sealed. When facing high-temperature flames, the first connecting strip 502, the second connecting strip 703, the upper outer cover 501 and the lower outer cover 702, which are made of polypropylene, provide flame isolation to prevent the sub-tape 1 and the mother tape 2 from directly contacting the fire source, thereby improving the flame-retardant effect of the mother tape 2. At the same time, the upper outer cover 501 and the lower outer cover 702 have ventilation holes 6 on both sides to ensure the dryness of the sub-tape 1 and the mother tape 2 and extend their service life.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
