Preferably, the surfaces of the first sheet-like substrate 100 facing away from the flexible fastener 200 and the second sheet-like substrate 300 facing away from the hook 400 are provided with adhesive components, and the adhesive components can be double-sided adhesive tapes, so that the first sheet-like substrate 100 and the second sheet-like substrate 300 are respectively adhered and fixed on the two mounting bodies, and the two mounting bodies are combined and separated.

When the hook and loop fastener assembly is required to be adhered, the second sheet-shaped substrate 300 and the first sheet-shaped substrate 100 are close to each other, the head 220 of the flexible fastener 200 can be abutted against the second sheet-shaped substrate 300, the hook portion of the hook piece 400 extends between at least two flexible fasteners 200, when the second sheet-shaped substrate 300 and/or the first sheet-shaped substrate 100 are subjected to an external force parallel to the first sheet-shaped substrate 100 or the second sheet-shaped substrate 300, the head 220 of the flexible fastener 200 can limit the movement of the hook piece 400, and when the second sheet-shaped substrate 300 and the first sheet-shaped substrate 100 are far away from each other, the hook portion of the hook piece 400 is abutted against the bottom of the head 220, that is, the head 220 is abutted against the inner surface of the hook portion of the hook piece 400, so that the hook piece 400 is limited from moving away from the first sheet-shaped substrate 100; the flexible fastener 200 and the hook 400 are not easily damaged after the magic tape assembly with the above structure is bonded and separated for many times, so that the bonding capability is stable continuously, and the service life of the magic tape assembly is prolonged.

It should be noted that, the maximum distance between the flexible fastener 200 and the first sheet substrate 100 is the distance between the free end of the head 220 of the flexible fastener 200 and the first sheet substrate 100, the maximum distance between the hook 400 and the second sheet substrate 300 is the distance between the outer surface of the hook portion of the hook 400 and the second sheet substrate 300, and when the hook 400 is inserted into the plurality of flexible fasteners 200 to make the second sheet substrate 300 and the first sheet substrate 100 close to each other, if the second sheet substrate 300 receives a horizontal external force, the hook 400 can drive the rod 210 to bend, and the gap between the hook 400 and the first sheet substrate 100 can provide a movable distance for the second sheet substrate 300 and the first sheet substrate 100 to approach each other, so as to delay the time for the hook and loop assembly to reach the maximum bearing capacity, thereby achieving a better bonding effect.

In some embodiments of the present utility model, the hook 400 and the second sheet substrate 300 are a unitary structure composed of a flexible material for the convenience of manufacturing the hook and loop assembly. The hook 400 and the second sheet-like substrate 300 may be made of polypropylene, nylon, polyester, or the like. For example, when polypropylene is used, the hook 400 and the second sheet substrate 300 may be obtained by an integral injection molding or injection molding method. Of course, in other embodiments, the second sheet-like substrate 300 and the hook 400 may be made of different materials, and the hook 400 may be formed on the second sheet-like substrate 300 by post-processing.

Referring to fig. 4, in some embodiments of the utility model, the cross-sectional area of the hook 400 tapers from the root of the hook 400 toward the end of the hook 400. It will be appreciated that if the hook 400 is manufactured by injection molding, the cross-sectional area of the hook 400 becomes smaller from the root of the hook 400 to the end of the hook 400, which is advantageous for drawing, and the bearing capacity of the individual hook can be improved, and the durability in use can be improved.

Referring to fig. 1 and 4, in some embodiments of the present utility model, the plurality of hook members 400 are divided into a plurality of first hook groups 41 and second hook groups 42 which are parallel to each other, the plurality of first hook groups 41 and the plurality of second hook groups 42 are alternately arranged in sequence, the first hook groups 41 have a plurality of first hooks aligned in a straight line, and the second hook groups 42 have a plurality of second hooks aligned in a straight line, and the directions of bending of the first hooks and the second hooks are opposite. It should be noted that, the first hook and the second hook are both one type of hook 400, wherein the bending directions of the first hook and the second hook are opposite, for example, the bending direction of the first hook is horizontal to the left, the bending direction of the second hook is horizontal to the right, and when the second sheet substrate 300 moves relative to the first sheet substrate 100 along the horizontal left direction, the head 220 of the flexible fastener 200 can abut against the inner side of the first hook to prevent the second sheet substrate 300 from moving relative to the first sheet substrate 100; when the second sheet-like base material 300 moves in the horizontal rightward direction with respect to the first sheet-like base material 100, the head 220 of the flexible fastener 200 can abut against the inner side of the second hooks to prevent the second sheet-like base material 300 from moving with respect to the first sheet-like base material 100, thereby ensuring that the second sheet-like base material 300 and the first sheet-like base material 100 can be stably bonded.

Referring to FIG. 5, in some embodiments of the utility model, the length dimension of the stem 210 is a and the dimension of the head 220 extending along the length of the stem 210 is b, satisfying 1.ltoreq.a/b.ltoreq.1.5. It should be noted that, when the hook 400 is inserted between the heads 220 of two adjacent rows of the flexible fasteners 200, the stem 210 of the flexible fastener 200 contacting with the hook 400 deforms in a direction away from the hook 400, and the flexible fastener 200 with the above dimension ratio limits the elastic deformation coefficient of the stem 210 within a suitable range, so that the stem 210 can deform and the hook 400 is not easily separated from the head 220 due to easy deformation, thereby ensuring the bonding effect of the hook and loop assembly.

In some embodiments of the present utility model, the flexible fastener 200 and the first sheet substrate 100 are a unitary structure composed of a flexible material for ease of manufacturing the hook and loop assembly. The flexible fastener 200 and the first sheet-like base material 100 may be made of polypropylene, nylon, polyester fiber, or the like. For example, when polypropylene is used, the flexible fastener 200 and the first sheet-like substrate 100 may be obtained by an integral injection molding or injection molding process.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

While embodiments of the present utility model have been shown and described, it will be understood by those of ordinary skill in the art that: many changes, modifications, substitutions and variations may be made to the embodiments without departing from the spirit and principles of the utility model, the scope of which is defined by the claims and their equivalents.
