Description

Technical Field

[0001] The utility model relates to the technical field of hook and loop fasteners, and more particularly to a fleece-surface hook and loop fastener. Background Art

[0002] There are some significant problems and limitations in the existing fleece-surface Velcro technology, which not only affect the convenience of product use, but may also lead to a shortened service life and safety hazards.

[0003] First of all, the structure of the fleece-surface Velcro in the prior art is usually relatively simple. Although this simplicity may bring certain advantages in the manufacturing process, it has obvious shortcomings in actual use and storage. The simple structural design often ignores the actual needs of users in daily life or work, resulting in the Velcro being difficult to effectively store when not in use. This inconvenience in storage may cause the Velcro to easily become entangled, deformed or contaminated with dust, which not only affects the appearance, but may also reduce its bonding effect.

[0004] Secondly, in response to the above-mentioned storage problem, some manufacturers have tried to use additional components to store the Velcro. Although this method can theoretically solve the storage problem, it faces new challenges in practical applications. The main problem lies in the design and use of these storage components: their installation and disassembly operations are usually cumbersome, involving multiple steps and complex operations. This cumbersomeness not only increases the usage time, but also increases the user's operational burden. More importantly, when the Velcro material becomes fatigued or damaged and needs to be replaced, the complicated disassembly and assembly process may hinder timely replacement, causing users to continue using Velcro with degraded performance, affecting the use effect and safety.

[0005] Finally, in order to solve the problem of cumbersome disassembly and assembly of storage devices, some manufacturers have adopted certain simplified component combinations to achieve quick disassembly and assembly of storage devices. Although these solutions have simplified the disassembly and assembly process to a certain extent and improved efficiency, they have brought new problems. The main problem is that these simplified designs are often too simple in structure, resulting in low overall stability and easy loosening. In daily use, the Velcro may be subjected to various external forces, such as pulling, bending, etc. The simple fixing structure may not be able to remain stable for a long time, causing the storage device to gradually loosen. Secondly, when subjected to accidental collisions or vibrations, this looseness may rapidly deteriorate and even cause the storage device to fall off completely. This will not only cause the Velcro to be unable to be effectively protected and stored, but may also cause damage or loss of the Velcro. Utility Model Content
