Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, specifically a zipper with an anti-slip structure. Background Technology
[0002] Zippers are extremely common connectors in modern life. During daily use, zipper heads often experience issues such as teeth getting stuck or falling out, leading to easy damage and the need for replacement. Current zipper heads are generally one-piece structures, making them inconvenient to disassemble freely and requiring professional tools for replacement. Furthermore, traditional one-piece zipper heads make it difficult to adjust the distance between the zipper head base and the zipper head cover. This can lead to teeth falling out when the distance is too large, or getting stuck when the distance is too small, hindering the stability of the zipper during operation. Utility Model Content

Detailed Implementation
[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] Example 1: As Figures 1-3 The zipper head includes a zipper head base 100 and a zipper head cover 200 rotatably connected to the top of the zipper head base 100. A first nut 120 is fixedly installed on the bottom inner wall of the zipper head base 100, and a second nut 210 is fixedly installed on the bottom inner wall of the zipper head cover 200. A screw 230 is threadedly connected to the inner wall of the first nut 120 and the second nut 210. An internal hexagonal groove 232 is formed on the top of the screw 230. An anti-detachment cover 240 is inserted and connected to the top of the zipper head cover 200. A hexagonal prism 250 is fixedly installed on the bottom inner wall of the anti-detachment cover 240. The hexagonal prism 250 is inserted and connected to the inner wall of the internal hexagonal groove 232.
[0026] The specific application scenario of this embodiment is as follows: By setting the zipper head base 100 and the zipper head cover 200 as separate structures, it is convenient to quickly replace the zipper head after it is damaged. By connecting the zipper head base 100 and the zipper head cover 200 together, the screw 230 is threadedly connected to the first nut 120 and the second nut 210 by the handwheel 231, thereby locking the zipper teeth between the zipper head base 100 and the zipper head cover 200, which facilitates quick replacement of the zipper head. At the same time, an anti-slip cover 240 is inserted and installed on the top of the zipper head cover 200, which can lock the screw 230, thereby preventing the screw 230 from loosening and improving the anti-slip effect of the zipper.
[0027] Example 2: As Figures 3-5A first connecting block 130 is fixedly installed on the top inner wall of the zipper head base 100, and a second connecting block 280 is fixedly installed on the bottom inner wall of the zipper head cover 200. The first connecting block 130 and the second connecting block 280 are connected by a flexible chain 131. The second nut 210 and the first nut 120 are symmetrically distributed vertically. The top of the zipper head cover 200 has an insertion hole 220, which is distributed at the four corners of the second connecting block 280. Insert rods 241 are fixedly connected at the four corners of the bottom inner wall of the anti-slip cover 240. The insert rods 241 are inserted into the inner wall of the anti-slip cover 240. A handle is fixedly connected to the top of the anti-slip cover 240, and a handwheel 231 is fixedly connected to the top outer wall of the screw 230.
[0028] The specific application scenario of this embodiment is as follows: the anti-slip cover 240 is inserted and installed on the top of the zipper head cover 200, so that the insert rod 241 is inserted and connected to the inner wall of the insertion hole 220, so that the anti-slip cover 240 is installed on the top of the zipper head cover 200, and the hexagonal prism 250 is inserted and installed on the inner wall of the internal hexagonal groove 232, thereby locking the screw 230, thereby preventing the connection between the screw 230 and the first nut 120 and the second nut 210 from loosening, thereby preventing the screw 230 from loosening and falling off during long-term use, and playing a locking role for the zipper head base 100 and the zipper head cover 200.
[0029] Example 3: As Figure 3 A support base 260 is fixedly installed on the top outer wall of the zipper head cover 200. The support base 260 is rotatably connected to the handle 261 via a pivot. A first limiting baffle 110 is fixedly connected to the top of the zipper head base 100. A second limiting baffle 270 is fixedly connected to the bottom inner wall of the zipper head cover 200. The first limiting baffle 110 and the second limiting baffle 270 cooperate to limit the opening and closing of the zipper teeth.
[0030] The specific application scenario of this embodiment is as follows: by setting the first limiting baffle 110 and the second limiting baffle 270 to engage and limit the zipper teeth, the opening and closing of the zipper teeth can be controlled.
[0031] The working principle of this utility model is as follows: When used by those skilled in the art, the zipper head base 100 and the zipper head cover 200 are rotated through the cooperation of the first connecting block 130, the second connecting block 280, and the flexible chain 131, so that the zipper head base 100 and the zipper head cover 200 clamp the zipper teeth, causing the zipper teeth on both sides to mesh. The zipper head base 100 and the zipper head cover 200 are then threaded together through the cooperation of the screw 230, the first nut 120, and the second nut 210, so that the bottom ends of the zipper head base 100 and the zipper head cover 200 are fixedly connected. The anti-slip cover 240 is inserted and installed on the top of the zipper head cover 200, so that the insert rod 241 is inserted and connected to the inner wall of the insertion hole 220. The anti-slip cover 240 is installed on the top of the zipper head cover 200, and the hexagonal prism 250 is inserted and connected to the inner wall of the internal hexagonal groove 232, thereby locking the screw 230 and preventing the connection between the screw 230 and the first nut 120 and the second nut 210 from loosening. This prevents the screw 230 from loosening and falling off during long-term use, and plays a locking role for the zipper head base 100 and the zipper head cover 200.
[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
