Description

Technical Field

[0001] This utility model belongs to the field of double-sided zipper pulls, specifically relating to a double-sided zipper pull and its zipper. Background Technology

[0002] Double-sided zippers are a technology used in zipper products that allows users to open or close the zipper from both sides. This design is typically used for items requiring flexibility and convenience, such as reversible jackets, and usually features a rotating zipper pull structure. The core feature of rotating zipper pulls and zippers is their double-sided pulling function. This means the zipper can be pulled simultaneously from both directions, making opening and closing the zipper more flexible and convenient. These zippers are typically made of high-strength, wear-resistant materials to ensure sufficient durability and reliability during use. Different materials can also provide different appearances and textures as needed. The manufacturing process of rotating zipper pulls and zippers is also an important part of their background technology. The manufacturing process of these zippers typically involves multiple steps, such as material cutting, stamping, and assembly. During manufacturing, the precision and quality of each component must be ensured to guarantee the performance and reliability of the entire zipper. The design of zipper pulls and zippers also needs to consider adaptability. Because different products and occasions have different requirements for zippers, rotating zipper pulls and zippers need to be flexible enough to adapt to different application scenarios. However, when the zipper pull comes off or there is no zipper pull, it will be quite inconvenient to pull the double-sided zipper and zipper.

[0003] Chinese patent CN1611162A discloses a sliding block with double connectors and a single release fork for zipper fasteners, which uses double connectors to pull the zipper, but does not disclose related technologies for zipperless operation.

[0004] Therefore, in view of the problems existing in the prior art, there is an urgent need to provide a double-sided zipper and its zipper to solve the problems existing in the prior art. Summary of the Invention

[0005] To address the problems in related technologies, this utility model proposes a double-sided zipper pull and its zipper. The zipper pull includes a zipper pull body and an annular component. The annular component is a U-shaped collar structure clamped on both sides of the zipper pull body. The fixing arms clamped on both sides of the zipper pull body are curved structures. The gripping part is formed by the height difference between the end and the middle of the fixing arm, so that the zipper pull can be pulled from both sides.

[0006] This utility model is implemented as follows:

[0007] A double-sided zipper pull includes a zipper pull body and an annular component disposed on the outer side of the zipper pull body. The zipper pull body includes two parallel clamping plates and a fixing part located between the two clamping plates. The fixing part is perpendicular to the two clamping plates and forms a zipper groove with the two clamping plates. A zipper strap that can be pulled open or closed is provided in the zipper groove.

[0008] The ring-shaped component has a U-shaped collar structure and is clamped in the fixing part of the slider body;

[0009] The annular component includes two fixed arms and a connecting arm that connects the two fixed arms into one unit. The two fixed arms are engaged on the outside of the fixed part and correspond to the positions of the two clamps respectively.

[0010] The end of the fixed arm away from the connecting arm is the end of the fixed arm; the outer side of the fixed arm is a planar or curved structure with the end protruding from the middle, and the part with the height difference formed forms a pinch part; the ring part is pulled by manually pinching the pinch part.

[0011] Preferably, the fixing arm is a curved structure with the end wider than the middle, and the middle of the two fixing arms is recessed towards the side where the pull head body is located to form the gripping part.

[0012] Specifically, the structure, which is wide at the end and narrow in the middle, makes it easier for the end to apply force to the fingertips when gripping the gripping part of the fixed arm, thus holding the fingertips in place and preventing the fingers from slipping, and making it more stable when pulling the ring part.

[0013] The concave curved structure in the middle allows you to hold your fingers in the recess, making it easy to grip the ring and pull it back and forth freely.

[0014] Preferably, the end of the fixed arm is provided with a rope hole, and each rope hole is provided with a pull rope.
