[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] like Figures 1 to 5As shown, the utility model is a hook-surface Velcro. As known to those skilled in the art, the existing Velcro has a short service life, and the hook-shaped structure of the hook surface is easily straightened, resulting in a decrease in bonding performance; and, during use, the soft fiber surface and the elastic fiber surface of the adhesive buckle 2 are easily separated by force, losing their bonding function.

[0024] In this embodiment, it includes a hook surface base layer 1, and a plurality of adhesive buckles 2 are arranged on the top surface of the hook surface base layer 1. The adhesive buckles 2 include a base 21, a connecting column 22 and a top block 23. The base 21 is fixedly connected to the hook surface base layer 1, and the connecting column 22 is arranged between the base 21 and the top block 23. The base 21 is a truncated cone with an upper bottom surface radius smaller than a lower bottom surface radius. The top block 23 is a hemispherical shape. A plurality of adhesive buckles 2 form a plurality of annular arrays and are arranged on the top surface of the hook surface base layer 1. An annular frame 3 is provided on the top surface of the hook surface base layer 1 and on the outside of the plurality of annular arrays.

[0025] The hook-side Velcro is provided, which cooperates with the fleece-side Velcro when used. The adhesive buckle 2 on the hook-side Velcro is inserted into the fleece surface, and the small and soft fiber round hairs on the fleece surface are entangled with the adhesive buckle 2. The top block 23 of the adhesive buckle 2 forms a hemispherical hook platform with an increased contact area with the round hairs, which can be firmly hooked and adhered to the round hairs, making the two not easy to peel off, so that the Velcro can be connected. Only when all the round hairs hooked and adhered to the hook platform formed by the top block 23 are separated from the top block 23 can the two Velcros be separated, which greatly improves the bonding effect of the Velcro and has a long service life. There is no need to worry about the adhesive hook being pulled The hook surface base 1 has a plurality of circular arrays formed by the plurality of adhesive buckles 2. The design of the circular array of the adhesive buckles 2 enables the adhesive buckles 2 to effectively hook the round hairs of the opposite hair surface in multiple directions, thereby increasing its flexibility of use, thereby improving the stability and reliability of adhesion. Even when subjected to pulling forces in different directions, the Velcro can maintain a good bonding effect. The annular frame 3 is set up, when the hook surface and the hair surface are torn apart by external force, the force can be transmitted well, and the entire hook surface can be driven to move to separate it from the hair surface.

[0026] Moreover, in this embodiment, an arc-shaped edge 4 is circumferentially provided at the bottom end of the bottom surface of the top block 23 , and the arc center point of the arc-shaped edge 4 is below the top block 23 .

[0027] By providing the arcuate edge 4, the arcuate edge 4 further improves the firmness of the adhesion between the top block 23 and the round hair hook, thereby further improving the bonding effect of the buckle.

[0028] Furthermore, in this embodiment, the height of the annular frame 3 is smaller than that of the adhesive buckle 2 , and the hardness of the annular frame 3 is greater than that of the hook surface base layer 1 .

[0029] The annular frame 3 is provided with a height smaller than the adhesive buckle 2 to ensure that the adhesive buckle 2 contacts the round hairs of the hair surface. The hardness of the annular frame 3 is greater than the hook surface base layer 1 to facilitate force transmission and driving.

[0030] Furthermore, in this embodiment, the distance between two adjacent annular arrays gradually increases from the outside to the inside, and the distance between two adjacent adhesive buckles 2 in the same annular array gradually increases from the outer annular array to the inner annular array.

[0031] During the use of hook-type Velcro, the outer adhesive buckles 2 are often subjected to greater external forces, causing them to easily separate from the corresponding round hairs, resulting in curling, which not only affects the bonding effect but also the appearance. By arranging the adhesive buckles 2 in a circular array, it is possible to ensure that the adhesive buckles 2 are evenly distributed, thereby improving the overall adhesion effect. At the same time, the density of the adhesive buckles 2 is gradually reduced from the outside to the inside. While maintaining a certain adhesion force, unnecessary adhesive buckles 2 can be reduced, making the Velcro more lightweight and flexible. Moreover, the gradually decreasing density of the adhesive buckles 2 can also reduce friction and wear between the adhesive buckles 2, thereby extending the service life of the Velcro. By rationally arranging the distribution of the adhesive buckles 2, the amount of material used can be reduced, thereby reducing production costs. The circular array and the gradually decreasing density of the adhesive buckles 2 design can optimize material use while ensuring performance.

[0032] Furthermore, in this embodiment, a plurality of adhesive buckles 2 are arranged in an array on the top surface of the hook surface base layer 1 and at the four corners outside the annular frame 3 .

[0033] Through such a setting, the bonding effect around the four corners of the Velcro can be ensured, making it difficult to separate, and it can also prevent the entire Velcro from being separated due to accidental pulling by external force.

[0034] Furthermore, in this embodiment, the bottom surface of the hook surface base layer 1 is also provided with a plurality of adhesive buckles 2 corresponding one-to-one to the plurality of adhesive buckles 2 on the top surface of the hook surface base layer 1 .

[0035] This arrangement means that each side of the hook-type Velcro has an adhesive buckle 2, which provides fixing options in two directions, increases flexibility of use, and can be used in more types of application scenarios. For example, in situations where repeated disassembly and installation are required, double-sided Velcro can provide better performance.

[0036] Furthermore, in this embodiment, a first drawstring 5 and a second drawstring 6 are respectively provided on both side surfaces of the hook surface base layer 1, and the first drawstring 5 and the second drawstring 6 are detachably connected via a connecting assembly.

[0037] The first pull tape 5 and the second pull tape are provided to facilitate peeling off the hook-side fastener and the loop-side fastener that are firmly adhered together. The user separates the fasteners by pulling the first pull tape 5 and the second pull tape.

[0038] Moreover, in this embodiment, the connecting component includes a female buckle 7 and a sub-buckle 8 adapted to the female buckle 7. An open groove 51 is provided at the end of the first drawstring 5, and the second drawstring 6 can pass through the open groove 51. A female buckle 7 is provided at the front end of the top face of the second drawstring 6. Several sub-buckles 8 with equal spacing are provided on the bottom surface of the first drawstring 5 and behind the open groove 51. A female buckle 7 is also provided at the front end of the bottom face of the second drawstring 6. Several sub-buckles 8 with equal spacing are provided on the top surface of the first drawstring 5 and behind the open groove 51.

[0039] Through the provided connecting assembly, the connecting assembly facilitates connecting the first draw strap 5 and the second draw strap 6 together. The second draw strap 6 passes through the open slot 51 on the first draw strap 5, and the mother buckle 7 is fastened with one of the child buckles 8 to complete the connection between the first draw strap 5 and the second draw strap 6. The Velcro can be pulled with one hand and both sides are evenly stressed, which is convenient for the user to operate.

[0040] When in use, the hook-side Velcro is matched with the fleece-side Velcro, and the adhesive buckle 2 on the hook-side Velcro is inserted into the fleece, and the small and soft fiber round hairs on the fleece are entangled with the adhesive buckle 2. The top block 23 of the adhesive buckle 2 forms a hemispherical hook platform, which increases the contact area with the round hairs and can be firmly hooked on the round hairs, making the two not easy to peel off, so that the Velcro can be connected, and the bottom end of the bottom surface of the top block 23 is provided with an arc-shaped edge 4 to further improve the firmness of the top block 23 and the round hair hook, thereby further improving the bonding effect of the fastener; the design of the annular array of the adhesive buckle 2 makes the adhesive buckle 2 can be used in multiple directions It effectively hooks the round hairs on the opposite fleece surface, and at the same time, gradually reduces the density of the adhesive buckles 2 from the outside to the inside, which can reduce unnecessary adhesive buckles 2 while maintaining a certain adhesion force, making the Velcro more lightweight and flexible; when the two Velcro strips need to be separated, the second draw tape 6 is passed through the open slot 51 on the first draw tape 5, and the mother buckle 7 is fastened with one of the child buckles 8 to complete the connection between the first draw tape 5 and the second draw tape 6. Pull the first draw tape 5 and the second draw tape 6, and the force can be well transmitted through the set annular frame 3, which can well drive the entire hook surface base layer 1 to move and separate it from the fleece surface.
