Description

Technical Field

[0001] The utility model belongs to the technical field of zippers, and particularly relates to an anti-slip zipper. Background Art

[0002] Zippers are connectors that connect or separate items by relying on a series of linked teeth. They are widely used in clothing, bags, tents, and other applications. Zippers consist of linked teeth, a slider, and upper and lower stops (front and back stops) or locking elements. The linked teeth are a key component, directly determining the zipper's lateral pull strength. A typical zipper consists of two chain straps, each with a row of linked teeth. The two rows are staggered, and the slider grips the linked teeth on both sides. The pull tab slides to engage or disengage the linked teeth.

[0003] Publication number CN 221410591 U, as retrieved, relates to a non-slip zipper. The key technical features of the zipper are as follows: a cam and a fixing assembly are provided. When the slider is pulled to the desired position, the tension assembly rotates clockwise and remains parallel to the top frame. The protrusion of the cam rotates to the bottom, pressing the top block, which pushes the cone head into the gap between the zipper teeth, thereby fixing the slider and preventing it from sliding due to vibration. Simultaneously, the second magnet and the first magnet attract each other due to opposite polarities, generating a pulling force on the tension assembly toward the slider, thereby preventing the tension assembly from flipping due to vibration.

[0004] The above process can facilitate the self-control and adjustment of the zipper during use, but there are still some defects in this process. When the zipper is inadvertently subjected to external force and slides relative to each other during use, it is easy to slip, which makes it inconvenient to limit the position of the zipper pull head. In view of this, we propose a new type of anti-slip zipper to solve the above problem. Utility Model Content
