Description

Technical Field

[0001] This utility model belongs to the field of zipper technology and relates to a quick-release zipper head. Background Technology

[0002] The zipper pull is an important component of a zipper. Located at the top of the zipper, it is typically made of metal or plastic. Zipper pulls come in a variety of designs and shapes, ranging from simple rectangles to complex patterns or decorations. Its main function is to provide a grip, allowing users to easily open or close the zipper by hand. The size and shape of the zipper pull need to match the zipper's teeth to ensure smooth sliding and good durability.

[0003] The current zipper pulls are inconvenient to install and disassemble during use, so it is particularly necessary to design a quick-release zipper pull. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a quick-release zipper pull.

[0005] The purpose of this utility model can be achieved through the following technical solution: A quick-release zipper head, comprising an upper pressure plate and a lower pressure plate, characterized in that the lower pressure plate is detachably connected to the chain post of the upper pressure plate by a snap-fit ​​method, the upper pressure plate has a circular through hole that penetrates the chain post, the lower pressure plate has a threaded hole, and a connecting stud passes through the circular through hole and the threaded hole to connect the upper pressure plate and the lower pressure plate, and a pull tab is detachably connected to the connecting stud.

[0006] The chain post has a connecting protrusion, and the lower pressure plate has a connecting groove that mates with the connecting protrusion.

[0007] Both the connecting protrusion and the connecting groove adopt a dovetail groove structure.

[0008] The pull tab includes a pull tab body with a connecting hook, and a limiting rod that cooperates with the connecting hook is hinged to the pull tab body.

[0009] The connecting stud includes a screw portion and a connecting portion with a connecting hole.

[0010] Compared with existing technologies, this quick-release zipper pull has the following advantages:

[0011] In this invention, the connection between the upper and lower pressure plates is achieved by inserting the connecting protrusion of the upper pressure plate into the connecting groove of the lower pressure plate, and then passing the connecting stud through the circular through hole and the threaded hole. That is, the pull tab is designed as a detachable structure, which makes it easy to disassemble or install the zipper head. Attached Figure Description

Detailed Implementation

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figures 1-7 As shown, this quick-release zipper pull includes an upper pressure plate 1 and a lower pressure plate 2. The lower pressure plate 2 is detachably connected to the chain post 101 of the upper pressure plate 1 by a snap-fit ​​connection. The upper pressure plate 1 has a circular through hole 103 that passes through the chain post 101. The lower pressure plate 2 has a threaded hole 202. A connecting stud 3 passes through the circular through hole 103 and the threaded hole 202, connecting the upper pressure plate 1 and the lower pressure plate 2. A pull tab 4 is detachably connected to the connecting stud 3.

[0022] The chain post 101 has a connecting protrusion 102, and the lower pressure plate 2 has a connecting groove 201 that mates with the connecting protrusion 102; specifically, both the connecting protrusion 102 and the connecting groove 201 adopt a dovetail groove structure.

[0023] The pull tab 4 includes a pull tab body 401 with a connecting hook. A limiting rod 402 that cooperates with the connecting hook is hinged on the pull tab body 401. In this embodiment, the limiting rod 402 adopts an existing structure and has an automatic spring-back function.

[0024] The connecting stud 3 includes a screw portion 302 and a connecting portion 301 with a connecting hole.

[0025] The upper pressure plate 1, lower pressure plate 2, connecting stud 3, and pull plate 4 can all be manufactured using existing methods.

[0026] In this utility model, by inserting the connecting protrusion 102 of the upper pressure plate 1 into the connecting groove 201 of the lower pressure plate 2, and then passing the connecting stud 3 through the circular through hole 103 and the threaded hole 202, the connection between the upper pressure plate 1 and the lower pressure plate 2 can be realized. That is, the pull tab 4 is designed as a detachable structure, so that the zipper head can be easily disassembled or installed.

[0027] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0028] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
