Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a zipper with a detachable structure. Background Technology

[0002] Zippers, a common clothing accessory in daily life, consist of two straps, each with a row of metal or plastic teeth, used to connect the edges of an opening. By using the zipper pull, the two rows of teeth can be pulled into the interlocking position to close the opening.

[0003] A search revealed a utility model patent in China, patent publication number CN219108861U, which discloses a zipper including a top stop body and a zipper pull. A protrusion is fixedly installed on the outer side of the top stop body, and a slot is formed on the inner side of the top stop body. A support is fixedly installed at the upper end of the zipper pull, and a pull tab is movably installed inside the support. One end of a spring piece is fixedly installed inside the support. This zipper has two locking blocks on both sides inside the zipper pull, connected to a second spring piece. The second spring piece flips due to elasticity. When the zipper pull is pulled to the top stop, the locking blocks move into the slot inside the top stop body, preventing the top stop from separating from the zipper pull. When the pull tab is pulled, the slider inside the zipper pull contacts the second spring piece, which moves inward along a groove inside the slider, causing the locking blocks to separate from the slot and unlock the top stop. This design is convenient, prevents the zipper pull from slipping, and the elastic components are located inside the zipper pull for better protection.

An operator places the corresponding zipper tooth of the garment into the zipper groove at the upper end of the base 001, and then slides the protrusion 201 at the lower end of the upper seat 002 into the groove 101 on the side wall of the base 001. The lower side of the protrusion 201 contacts the inclined wall of the locking block 103. The locking block 103 automatically slides into the groove 102. After the protrusion 201 is completely slid into the slide groove 101, the groove 102 and the locking groove 202 are aligned. The locking block 103 slides out from the groove 102. At the same time, part of the locking block 103 slides into the locking groove 202 to lock and fix the protrusion 201. At the same time, the top post 205 is pushed upward to quickly fix the upper seat 002 onto the upper end of the base 001. Meanwhile, the corresponding chain tooth on one side is located in the chain groove at the lower end of the upper seat 002. When it is necessary to replace or disassemble the base 001 and the upper seat 002, the two top posts 205 slide downward to push out part of the locking block 103 located in the locking groove 202. Then, the upper seat 002 is manually pulled horizontally to make the protrusion 201 slide out from the slide groove 101, thereby quickly disassembling and separating the upper seat 002 from the base 001.

[0024] A spring 104 is fixedly connected to the bottom of the groove 102. The end of the spring 104 is fixedly connected to the lower end of the locking block 103. Through the elasticity of the spring 104, the locking block 103 inside the groove 102 is pushed upward.

The lower end of the rod 209 is fixedly connected to the upper end of the movable plate 204. When the movable block 208 slides, it drives the rod 209 to slide. The rod 209 pushes the movable plate 204 downward to slide downward.

[0028] The upper part of the upper seat 002 is provided with a pull tab 210, which is slidably connected to the movable block 208. By sliding the pull tab 210 laterally, the movable block 208 drives the upper seat 002 and the base 001 to slide laterally.

[0029] In this utility model, the operator places the corresponding side chain tooth of the garment into the upper chain groove of the base 001, and then slides the protrusion 201 at the lower end of the upper seat 002 into the slide groove 101 on the side wall of the base 001. The lower side of the protrusion 201 contacts the inclined wall of the locking block 103. The locking block 103 slides into the groove 102. After the protrusion 201 is completely slid into the slide groove 101, the groove 102 and the locking groove 202 are aligned. Through the elasticity of the spring 104, the locking block 103 inside the groove 102 is pushed upward. Part of the locking block 103 slides into the locking groove 202 to lock and fix the protrusion 201. At the same time, the top post 205 is pushed upward to fix the upper seat 002 to the upper end of the base 001. Meanwhile, the corresponding side chain tooth is located in the lower chain groove of the upper seat 002.

[0030] When it is necessary to replace or disassemble the base 001 and the upper seat 002, manually press down on the movable block 208 to make it slide inside the slot 207. The movable block 208 drives the rod 209 to slide, and the rod 209 pushes the movable plate 204 downward. The movable plate 204 drives the top column 205 to slide downward, pushing out part of the locking block 103 located inside the slot 202. At the same time, the spring 206 is compressed. Then, manually pull the upper seat 002 horizontally to make the protrusion 201 slide out from the slide groove 101, thus disassembling and separating the upper seat 002 from the base 001.

[0031] After the base 001 and the upper seat 002 are removed, the elasticity of the spring 104 pushes the locking block 103 inside the groove 102 upward, and the elasticity of the spring 206 pushes the movable plate 204 upward to slide. The movable plate 204 drives the top column 205 to slide. At the same time, the movable plate 204 pushes the movable block 208 to slide through the rod 209, thereby causing multiple components to automatically reset.
