Description

Technical Field

[0001] This utility model belongs to the field of zipper technology, and in particular relates to a double-sealed waterproof zipper. Background Technology

[0002] Zippers are commonly used in clothing, bags and other products, and are a common accessory. Currently, many products, especially outdoor products, have high requirements for waterproof performance, so waterproof zippers have appeared on the market.

[0003] According to a public announcement (announcement number: CN 214759529U), a waterproof zipper includes a chain belt with two rows of teeth. One end of the chain belt has an upper stop, and a zipper head is mounted on each tooth. The upper stop has a gap. The zipper head includes a base and a pull tab. The base slides with the teeth. A post is provided inside the base for opening or engaging the teeth. The shape of the post matches the gap, and the post is engaged within the gap. The front end of the base forms a receiving space to accommodate the upper stop. A waterproof membrane layer is provided on the surface of the chain belt.

[0004] In the aforementioned application, the interaction between the zipper head and the zipper teeth makes it difficult to fix the zipper head when it is pulled to the top of the zipper teeth. This causes the zipper head to loosen when subjected to the impact of water, which in turn causes the zipper teeth to separate. Therefore, we propose a double-sealed waterproof zipper. Utility Model Content

[0005] The purpose of this invention is to provide a double-sealed waterproof zipper. Through the cooperation of components such as the zipper lock, sealing strip, and fixing block in the sealing structure, when the zipper body is used, the user pulls the pull ring upwards, causing the zipper lock to move. The internal structure of the zipper allows the first and second chain teeth to engage, simultaneously engaging the sealing strip and the inlay strip, thus achieving a double seal and forming a complete waterproof barrier. When the zipper moves to the top, the connecting rod causes the two semi-circular blocks to overlap. At this point, the pull ring moves to the back via the limiting strip and engages with the semi-circular blocks. The fixing block moves outwards via a return spring, securing the pull ring. This design achieves a double-sealed and fixed effect on the zipper body, effectively preventing the zipper from loosening due to water impact and solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a double-sealed waterproof zipper, including a zipper body, a first zipper tooth fixedly connected to the side of the zipper body, a second zipper tooth fixedly connected to the side of the zipper body, and a sealing structure provided on the side of the zipper body.

[0008] The sealing structure includes a zipper, one end of which is slidably connected to the side of the first chain tooth, the other end of which is slidably connected to the side of the second chain tooth, a limit strip is fixedly connected to the side of the zipper, a pull ring is slidably connected to the side of the limit strip, a sealing strip is fixedly connected to the side of the zipper body, and an inlay strip is fixedly connected to the other side of the zipper body.

[0009] Furthermore, a connecting rod is fixedly connected to the side of the zipper body, and a semi-circular block is fixedly connected to the end of the connecting rod away from the side of the zipper body. The function of the semi-circular block is to be embedded with the pull ring when the first zipper tooth and the second zipper tooth are engaged.

[0010] Furthermore, a spring hole is provided on the circumferential surface of the semicircular block, and a return spring is fixedly connected inside the spring hole. A fixing block is fixedly connected to the end of the return spring away from the inside of the spring hole. The function of the fixing block is to fix the semicircular block and the pull ring after they are embedded, so as to prevent the semicircular block and the pull ring from falling off.

[0011] Furthermore, the fixing block is elastically connected to the inside of the spring hole via a reset spring, and a stop block is fixedly connected to the side of the zipper body. The function of the stop block is to prevent the zipper from falling off the zipper body during the pulling process.

[0012] Furthermore, the zipper is made of metal, and the sealing strip and the inlay strip are made of nylon. The purpose of making the zipper of metal is to improve its corrosion resistance, and the purpose of making the sealing strip and the inlay strip of nylon is to ensure tight waterproofing when the sealing strip and the inlay strip are engaged.

[0013] Furthermore, the number of connecting rods, spring holes, and fixing blocks is set to two, and they are symmetrical to each other along the vertical central axis of the zipper body. The function of setting the number of connecting rods, spring holes, and fixing blocks to two, and symmetrical to each other along the vertical central axis of the zipper body, is that the two fixing blocks prevent the first and second zipper teeth from being separated by external force after they are engaged.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes the interplay between components such as the zipper, sealing strip, and fixing block in a sealed structure. When the zipper body is in use, the user pulls the pull ring upwards, causing the zipper to move. Through the internal structure of the zipper, the first and second chain teeth engage, simultaneously engaging the sealing strip and the inlay strip, thus achieving a double-layer seal and forming a complete waterproof barrier. When the zipper reaches its top, the connecting rod causes the two semicircular blocks to overlap. At this point, the pull ring moves to the back via the limiting strip and engages with the semicircular blocks. The fixing block moves outwards via the return spring, securing the pull ring. This design achieves a double-layer sealing and fixing effect on the zipper body, effectively preventing the zipper from loosening due to water impact.
