Description

Technical Field

[0001] This utility model relates to the field of zipper technology, specifically to a magnetically self-locking zipper. Background Technology

[0002] Zippers, as a common connector, are widely used in clothing, bags, tents and other items. Traditional zippers usually use the mechanical engagement of the zipper head and zipper teeth to achieve closure, but they often have problems such as insecure closure and easy accidental opening. Therefore, it is particularly important to develop a magnetic self-locking zipper.

[0003] Referring to a magnetic self-locking zipper with publication number CN222129537U, it includes a fabric chain belt, chain teeth, a zipper head, and a pull plate. Chain teeth are fixedly connected to the fabric chain belt, and a zipper head is installed between two left and right fabric chain belts. The upper end of the zipper head is connected to a pull plate via a pivot. It also includes guide rods fixedly connected to the left and right sides of the zipper head, with pressure rollers mounted on the guide rods. The pressure rollers are covered with rubber sleeves. The movement of the zipper head drives the pressure rollers to move synchronously, thereby leveling the surrounding area. The board is equipped with a plug rod, and the side of the fabric chain is fixedly connected to a magnetic post with a positioning hole. This magnetically self-locking zipper can magnetically lock the zipper head after it moves to the corresponding position, preventing the zipper head from slipping due to force. At the same time, it can level the surrounding area when the zipper head moves. As can be seen from the above, although this zipper can be used well, it is usually not convenient to plug and close adjacent zipper teeth after closing, making it difficult for the zipper to achieve the expected closing effect, and further improvement is needed. Utility Model Content

[0004] The purpose of this invention is to provide a magnetically self-locking zipper to solve the problem mentioned in the background art that although zippers can be used well, it is usually inconvenient to insert adjacent zipper teeth to close them after closing, making it difficult for the zipper to achieve the expected closing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a magnetically self-locking zipper, comprising a first zipper tape, a lower limit block at the bottom of the first zipper tape, a second zipper tape at the top of the lower limit block on one side of the first zipper tape, a plurality of first zipper teeth on the inner wall of the first zipper tape, a plurality of second zipper teeth on the inner wall of the second zipper tape, slots at the top of both the first and second zipper teeth, inserts at the bottom of both the first and second zipper teeth, zipper heads mounted on the outer walls of the first and second zipper teeth between the first and second zipper tapes, a U-shaped seat at the center of the surface of the zipper head, a pull handle fitted on the outer side of the U-shaped seat, and a handle groove at the lower end of the inner part of the pull handle.

[0006] Preferably, both the upper ends of the surfaces of the first zipper tape and the second zipper tape are provided with magnetic plates, and one side of the magnetic plate is provided with a circular plate hole, both ends of which extend to the outside of the magnetic plate.

[0007] Preferably, a first upper limit block is fixed to the top end of the first zipper tape, and a second upper limit block is fixed to the top end of the second zipper tape.

[0008] Preferably, a first base is provided on both outer walls of the top of the U-shaped seat, and a telescopic rod is provided at the end of the first base away from the U-shaped seat.

[0009] Preferably, a second base is fixed to the end of the telescopic rod away from the first base, and a magnetic column is provided at the end of the second base away from the telescopic rod.

[0010] Preferably, a spring is wound around the outer wall of the telescopic rod, and the two ends of the spring are respectively connected to the inner walls of the first base and the second base.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the magnetic self-locking zipper not only ensures the closing effect of the zipper during use, but also achieves the purpose of magnetic self-locking of the zipper head, so as to reduce the phenomenon of displacement and slippage of the zipper head, and ensure the service life of the zipper.

[0012] (1) By providing slots at the top of both the first zipper tooth and the second zipper tooth, and inserting blocks at the bottom of both the first zipper tooth and the second zipper tooth, when the zipper is closed, the first zipper tooth and the second zipper tooth mesh with each other. At this time, the inserting block at the bottom of the second zipper tooth is inserted into the slot at the top of the first zipper tooth, and the inserting block at the bottom of the first zipper tooth is inserted into the slot at the top of the second zipper tooth, so as to achieve the purpose of inserting and closing the first zipper tooth and the second zipper tooth, thereby ensuring the closing effect of the zipper during use.

[0013] (2) By pulling the zipper head upward, the zipper head is positioned at the upper end between the first zipper tape and the second zipper tape. Due to the elastic pressure applied by the spring to the second base, it works with the telescopic rod to drive the magnetic column to move horizontally, so as to insert the magnetic column into the circular plate hole. Due to the principle of opposite poles attracting each other, the magnetic plate is attracted to the outer wall of the magnetic column, so as to achieve the purpose of magnetic self-locking of the zipper head, thereby reducing the phenomenon of displacement and slippage of the zipper head.

[0014] (3) By setting a lower limit block at the bottom of the first zipper belt and the second zipper belt, and setting a first upper limit block and a second upper limit block at the top of the first zipper belt and the second zipper belt respectively, the zipper head can be blocked and limited by the upper and lower ends of the first zipper belt and the second zipper belt, so as to reduce the phenomenon of the zipper head falling off the outer wall of the first zipper tooth and the second zipper tooth, thereby ensuring the service life of the zipper.
