Description

Technical Field

[0001] The utility model relates to the technical field of fastener structures, in particular to a composite hook and loop fastener structure. Background Art

[0002] Velcro, also known as hook and loop fastener or snap fastener, is a commonly used connecting material on clothes. It has two sides of the molecule and is widely used in clothing, shoes, hats, gloves, bags, sofas, vehicles and ships, seat cushions, aviation supplies, raincoats, curtains, toys, sleeping bags, sports equipment, audio equipment, medical equipment, tents, bicycle covers, various military products, electronic wires, chargers, display appliances, etc.

[0004] When the above-mentioned device is in use, the existing device utilizes buckle posts and limiting holes to make the binding effect of the Velcro main body better and more reliable, and is easy to use, avoiding the phenomenon of loose fixation. However, in actual use, the Velcro will be detached due to the pulling force at both ends, resulting in poor effect and detachment of the buckle posts. For this reason, the present device changes the traditional single-layer adhesion method and increases the adhesion effect of the Velcro. In addition, during the use of the Velcro, long-term wear will cause damage to the thorny surface and the rough surface, and cause the adhesion effect to deteriorate. Therefore, a composite Velcro structure that solves the above-mentioned problems is needed. Utility Model Content
