Technical Field

[0001] This utility model relates to the field of zipper head technology, specifically to a zipper head with an assembled structure. Background Technology

[0002] The zipper pull is the core component that controls the opening and closing of the zipper. It is usually made of metal or plastic and is responsible for engaging or disengaging the chain teeth on both sides. It is also called the zipper slider. In order to facilitate the assembly and installation of the zipper pull, a modular zipper pull structure is required.

[0003] Traditional assembled zipper heads are mostly manufactured by welding. However, due to long-term use, traditional zipper heads may jam inside the zipper, making it difficult to move. This can damage the zipper under strong pulling, affecting the use of the device. Furthermore, the zipper head may break under pulling, affecting the stable movement of the zipper head.

[0006] As a preferred technical solution of this utility model, a first magnet plate is fixedly installed on the inner wall of the bottom of the limiting groove, a limiting plate is rotatably connected to the inner wall of the limiting groove, and the shape and size of the outer edge of the limiting plate are adapted to the shape and size of the inner wall of the second slide groove and the inner wall of the first slide groove. A pull rod is fixedly installed on the top of the limiting plate, and a second magnet plate is fixedly installed on the inner wall of the bottom of the limiting plate, and the bottom of the second magnet plate is attracted to the top of the first magnet plate.

[0007] As a preferred embodiment of this utility model, a spring is fixedly connected to the inner wall of the second arc-shaped rod, and the end of the spring away from the second arc-shaped rod is fixedly connected to the side of the square plate. A baffle is fixedly mounted on the side of the square plate, and an auxiliary frame is fixedly mounted on the side of the baffle. The inner wall of the auxiliary frame is slidably connected to the side of the first arc-shaped rod. Pull heads are movably sleeved on the outer edges of the first arc-shaped rod and the outer edges of the second arc-shaped rod.

[0008] As a preferred technical solution of this utility model, a limiting frame is fixedly installed on the side of the baffle away from the auxiliary frame, and the inner wall of the limiting frame is slidably connected to the side of the arc-shaped rod II. Rubber pads are fixedly installed on the bottom of the limiting frame, the bottom of the baffle, and the bottom of the auxiliary frame.

[0009] As a preferred technical solution of this utility model, there are two magnet plates and two magnet plates, and the two magnet plates are respectively arranged facing each other on the inner wall of the limiting groove and the inner wall of the bottom of the limiting plate.

[0010] In a preferred embodiment of this invention, the number of springs is two, and the connection structure of the two springs is completely identical.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The zipper head of this assembled structure, through the cooperation of the limiting plate and the pull rod, allows the lower locking plate and the upper locking plate to be disassembled when needed. By rotating the pull rod, the limiting plate is rotated, which in turn assists the outer edge of the limiting plate to rotate within the inner wall of the limiting groove. This, in turn, assists the misalignment of magnet plate one and magnet plate two. Then, the pull rod moves along the inner wall of slide groove two and the inner wall of slide groove one, thereby assisting in the disassembly of the central column and the upper locking plate, thus facilitating convenient repair of the zipper.

[0012] 2. The zipper head of this prefabricated structure, through the cooperation of the arc-shaped rod two and the square plate, allows the square plate to move towards the arc-shaped rod two when the zipper head is damaged. This helps to move the side of the square plate away from the inner wall of the arc-shaped rod one, thereby assisting in the disassembly of the zipper head from the outer edge of the arc-shaped rod one, facilitating the replacement of the zipper head. Furthermore, when the zipper head is installed, the side of the square plate is used to limit the movement against the inner walls of the arc-shaped rod one and the inner walls of the arc-shaped rod two, and the inner wall of the auxiliary frame is used to limit the movement against the side of the arc-shaped rod one, while the inner wall of the limiting frame is used to limit the movement against the side of the arc-shaped rod two. This ensures that the zipper head can be used stably and prevents it from detaching during use. Attached Figure Description
