[0001] The utility model relates to the technical field of zippers, in particular to a zipper structure. Background Art

[0002] As one of the ten great inventions of the 20th century, the zipper has penetrated into human daily life and many industries, and is widely used in aerospace, deep ocean, national defense and military, daily civilian use, industry, agriculture and fisheries, and medical care and environmental protection.

[0003] The utility model patent application document with publication number "CN221785517U" discloses a zipper structure, which is mainly composed of a zipper head, a fixing ring, a pull ring and an anti-stuck edge element. This technical solution sets an anti-stuck edge element and uses an arc-shaped dividing block to separate the inner fabric of the clothes to prevent the inner fabric from being hinged into the zipper head. By setting a detachable partition between the lower pull block and the upper pull block, the lower pull block can be separated from the upper pull block, and the fabric hinged into the zipper head can be loosened. The operation is simple and convenient to deal with the situation where the fabric is hinged into the zipper head and cannot be removed.

[0004] The zipper structure disclosed in the above document has the following defects: the upper pull block and the lower pull block in this technical solution are fixed and installed by means of screws. However, when the user is running, the zipper head on the clothes will vibrate. Under the action of long-term vibration, the connection of the screw may become loose, causing the screw to detach from the threaded hole, resulting in the separation of the upper pull block and the lower pull block.

[0005] It can be seen from this that the upper pull block and the lower pull block of the existing zipper structure do not have a good connection component, and it is necessary to improve the existing shortcomings and provide a zipper structure. Utility Model Content
