Description

Technical Field

[0001] The present application relates to the technical field of zippers, and in particular to a self-locking zipper. Background Art

[0002] A zipper is a fastener that connects or separates items by means of continuously arranged chain teeth. It is now widely used in clothing, bags, tents, etc. Its characteristics are: 1. A fastener consisting of two strips with a row of metal or plastic teeth on each side, used to connect the edges of an opening (such as clothing or bag openings), with a sliding piece that pulls the two rows of teeth into an interlocking position to close the opening; 2. A chain that is attached to an object (as an object to be lifted or lowered) to tighten, stabilize or guide the object.

[0003] The patent document with announcement number CN214802818U proposes a self-locking zipper, including two zipper tapes and a zipper head connected to the two zipper tapes, a pull ring connected to the zipper head, an active connector connected to the pull ring, a passive connector connected to the active connector at the end of the zipper tape, the pull ring includes a main board connected to the zipper head and connecting plates arranged on both sides of the main board, and the active connector is connected to the connecting plate. An active connector is arranged on the zipper head, and a passive connector is arranged on the zipper tape. When the zipper is used to close the clothes, the active connector can be connected to the passive connector, which will limit the position of the zipper head. When the human body moves, it will pull the zipper, but the zipper head will not move over a large range, ensuring the stability of the zipper connection and preventing the clothes from being frequently torn open.

[0004] The above cases exist in actual use. Since each person pulls the zipper to a different position, the position of the self-locking mechanism used in the above cases is relatively fixed, which is difficult to meet people's needs during use. For this reason, we propose a self-locking zipper. Utility Model Content

[0005] In view of the deficiencies of the prior art, the present application provides a self-locking zipper, which overcomes the deficiencies of the prior art and aims to solve the problems in the prior art.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a self-locking zipper, comprising a zipper tape and a fixed plate, the front side of the zipper tape is fixedly connected to an iron bar, one side of the zipper tape is fixedly connected to a zipper tooth, the outside of the zipper tooth is slidably connected to a zipper head, the front side of the zipper head is rotatably connected to a pull ring, the outside of the pull ring is fixedly connected to a clamping sleeve, one side of the fixed plate is fixedly connected to a card plate, the top and bottom of the card plate are both slidably connected to a clamping block, the inside of the card plate is fixedly connected to a limiting column, a spring is arranged on the outside of the limiting column, the top and bottom of the spring are respectively fixedly connected to the bottom and top of two clamping blocks, and the top and bottom of the fixed plate are both provided with magnet sheets that cooperate with the iron bar.

[0007] As a preferred technical solution of the present application, the top and bottom of the sleeve are provided with a snap-in hole adapted to one end of the card block.

[0008] By adopting the above technical solution, the clamping block can be limited by the clamping hole to achieve fixation between the clamping sleeve and the clamping plate.

[0009] As a preferred technical solution of the present application, the interior of one side of the ferrule is adapted to the exterior of one side of the card plate.

[0010] By adopting the above technical solution, the card sleeve can be clamped on the outside of the card plate.

[0011] As a preferred technical solution of the present application, the width of the magnet sheet is smaller than the width of the iron bar, the iron sheet is located on one side of the zipper head, and the fixing plate is located directly in front of the iron sheet.

[0012] By adopting the above technical solution, the fixing plate cooperates with the magnet sheet to be adsorbed on the front side of the iron bar.

[0013] The beneficial effects of the present application are as follows: by providing iron bars, clamping sleeves, clamping blocks, limit posts, springs, clamping plates and fixing plates, the zipper head can be pulled up according to the user's habits when the zipper is used, and fixed at any position by adsorption of the magnet sheet, which can meet the needs of the user and is worthy of promotion and use.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] Reference Figure 1-3A self-locking zipper comprises a zipper tape 1 and two fixing plates 11. An iron bar 2 is connected to the front of the zipper tape 1 and the positions corresponding to the two fixing plates 11. A zipper tooth 3 is fixedly connected to one side of the zipper tape 1. A zipper head 4 is slidably connected to the outside of the zipper tooth 3. A pull ring 5 is rotatably connected to the front of the zipper head 4. Magnet sheets are arranged on the top and bottom of the fixing plate 11. The width of the magnet sheet is smaller than the width of the iron bar 2. The iron bar 2 is located on one side of the zipper head 4. The fixing plate 11 is located directly in front of the iron bar 2. When using the zipper, the zipper head 4 is pulled to a suitable position outside the zipper tooth 3, and the pull ring 5 is released to make the fixing plate 11 close to the iron bar 2, so that the fixing plate 11 is adsorbed on the front of the iron bar 2 through the magnet sheet, thereby completing the self-locking of the zipper.

[0020] In addition, the outside of the pull ring 5 is fixedly connected to a sleeve 6, one side of the fixed plate 11 is fixedly connected to a card plate 10, the top and bottom of the card plate 10 are slidably connected to a card block 7, the inside of the card plate 10 is fixedly connected to a limiting column 8, the outside of the limiting column 8 is provided with a spring 9, the top and bottom of the spring 9 are respectively fixedly connected to the bottom and top of the two card blocks 7, the top and bottom of the fixed plate 11 are provided with magnet sheets, the top and bottom of the sleeve 6 are provided with card holes that are compatible with one end of the card block 7, the inside of one side of the sleeve 6 is compatible with the outside of one side of the card plate 10, when the user does not need to self-lock the zipper, the card block 7 can be pressed to make the card block 7 embedded in the inside of the card plate 10, and then the card plate 10 can be pulled out from the inside of the sleeve 6, and the fixed plate 11 can be removed, thereby preventing the zipper from self-locking.

[0021] Working principle: When using the zipper, pull the zipper head 4 outside the zipper teeth 3 to the desired position, loosen the pull ring 5, so that the fixing plate 11 is close to the iron bar 2, so that the fixing plate 11 is adsorbed on the front of the iron bar 2 through the magnet sheet, and then the self-locking of the zipper is completed. Finally, when the user does not need to self-lock the zipper, the card block 7 can be pressed so that the card block 7 is embedded in the inside of the card plate 10, and then the card plate 10 can be pulled out from the inside of the card sleeve 6, and the fixing plate 11 can be removed, thereby preventing the zipper from self-locking.

[0022] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
