Technical Field
[0001] This utility model relates to a hook and loop, and more particularly to an elastic hook and loop integrally molded from synthetic resin. Background Technology
[0002] Please refer to Figures 14 to 16 This is a partial schematic diagram of the existing standardized structure of an elastic hook and loop 3 integrally molded from synthetic resin. Please refer to the diagram. Figure 14 The elastic hook and loop 3 includes an integrally formed hook and loop body 3a and a movable member 3b, and the hook and loop body 3a and the movable member 3b form a ring 3c; wherein the hook and loop body 3a has a hook 3e extending from a base 3d of the hook and loop body 3a; wherein the synthetic resin hook and loop 3 has a front end 3f and a rear end 3g based on the base 3d, the base 3d is the rear end 3g, and the other end extending outward from the base 3d relative to the rear end 3g is the front end 3f; wherein the movable member 3b has a The outer front closing surface 3h is used to close with the inner front closing surface 3j of a curved portion 3i of the hook body 3a, and the outer front closing surface 3h extends to the inner front closing surface 3j; wherein the movable member 3b is elastically movable relative to the base 3d, which serves as a fulcrum, so that the movable member 3b can move into the ring 3c or return to its original position from the inside of the ring 3c to the outside; wherein when the movable member 3b is subjected to the force of a finger 2 (such as... Figure 15 As the moving part 3b moves inward toward the ring 3c (as indicated by arrow A), the outer closing surface 3h of the front end moves away from the inner closing surface 3j of the front end, forming a released closing state; in this released closing state, a hook-in space 3k is formed between the outer closing surface 3h of the front end and the inner closing surface 3j of the front end; when the moving part 3b is released from force, the outer closing surface 3h of the front end moves elastically from the inside to the outside (as indicated by arrow A). Figure 16 As indicated by arrow B in the diagram, it returns to its original position and closes with the inner closed surface 3j of the front end, thus forming a closed state.
[0003] However, when the existing elastic hook 3 is in the open / closed state, the user's finger 2 can easily slide into the hooking space 3k through the movable part 3b, making it easy for the finger 2 to be pinched and causing inconvenience in operation, resulting in a poor user experience. In addition, because the existing elastic hook 3 allows the user's finger 2 to enter the hooking space 3k, the space of the hooking space 3k is forced to shrink. This makes it difficult for the user to hook other items when using the elastic hook 3, as the space of the hooking space 3k is reduced. The same problem also exists when the elastic hook 3 is to be removed from other items, making it difficult to remove.
[0004] Therefore, an elastic hook and loop made of synthetic resin that prevents fingers from slipping into the hook and loop's hook-loop space is urgently needed by the relevant industries. Utility Model Content

Detailed Implementation
[0036] With reference to the accompanying drawings, the structure and technical features of this utility model are described in detail below. The accompanying drawings are only used to illustrate the structural relationships and related functions of this utility model. Therefore, the dimensions of each component in the accompanying drawings are not drawn to actual scale and are not intended to limit this utility model.
[0037] Please refer to Figure 1 , Figure 2 , Figure 8 and Figure 12 As shown, this utility model provides an elastic hook and loop 1 integrally molded from synthetic resin. The elastic hook and loop 1 includes an integrally molded hook and loop body 10 and a movable member 20, and the hook and loop body 10 and the movable member 20 form a ring 1a. The synthetic resin is cheaper than commonly used metal materials, which helps to reduce manufacturing costs.
