Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a pull tab and a zipper. Background Art

[0002] With the increasing diversification of clothing and luggage designs, zippers, as key accessories in these products, are attracting increasing attention for both their functionality and aesthetics. Zippers typically consist of a slider and a tab. The slider opens and closes the zipper, while the tab is designed for easy grip and operation. To further enhance grip and comfort, a pull tab is often added to the tab.

[0003] As an additional accessory, a pull tab is designed to provide a larger grip area and a more comfortable grip, thereby enhancing the user experience. For example, Chinese patent application number CN202122070461.4 proposes an adjustable pull tab structure. This structure has an extension portion passing through a through hole in the pull tab and further through a fixed frame. Finally, a stopper engages with the fixed frame to achieve post-assembly of the pull tab on the pull tab.

[0004] However, this existing tab installation method has some significant drawbacks. First, the assembly process is relatively complex, requiring the extension to be fully inserted through the tab's mounting hole, then through the fixed frame, before finally engaging. This process involves numerous assembly steps and is relatively inefficient, making it difficult to meet the needs of large-scale production or rapid tab replacement.

[0005] Therefore, how to provide a pull tab to simplify the assembly process and improve installation efficiency is a technical problem that those skilled in the art currently need to solve. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] See also Figure 1-Figure 2 The present application provides a pull tab, including a connecting belt 1, a clamping member 2 is provided at one end of the connecting belt 1, and a force-applying member 3 is provided at the other end. A clamping base 4 is also provided on the connecting belt 1 between the clamping member 2 and the force-applying member 3. The clamping member 2 can pass through the through hole of the pull tab 5 and realize a clamping connection with the clamping base 4, thereby completing the connection between the connecting belt 1 and the pull tab 5.

[0032] Specifically, the connecting belt 1 is made of a flexible material and has a certain strength and flexibility;

[0033] The clamping member 2 is arranged at one end of the connecting belt 1, and is used to pass through the through hole of the pull tab 5 and realize a clamping connection with the clamping base 4; the force-applying member 3 is arranged at the other end of the connecting belt 1, and is used to provide a gripping area for the user; the force-applying member 3 can be designed into various shapes, such as ring-shaped, flat, etc., to improve the user's comfort; the clamping base 4 is located between the clamping member 2 and the force-applying member 3, and is fixedly connected to the pull tab 5.

[0034] The present application provides a pull tab connection method in which the user only needs to pass the clamping member 2 through the through hole of the pull tab 5 and insert it into the clamping base 4 to complete the assembly without the need for complicated tools or steps, thereby greatly improving production efficiency.

[0035] Specifically, the width of the clamping member 2 is smaller than the diameter of the through hole of the pull tab 5 , so that the clamping member 2 can pass through the through hole of the pull tab 5 at an inclined angle.

[0036] Based on the above embodiment, the clamping base 4 is symmetrically provided with clamping grooves 41 on both sides, and the clamping member 2 includes a clamping seat 21, one side of the clamping seat 21 is connected to the connecting belt 1, and the other side is symmetrically provided with clamping claws 22 that cooperate with the clamping grooves 41.

[0037] Specifically, a card slot 41 is symmetrically provided on the left and right sides of the snap-fit ​​base 4, and the clamping member 2 includes a clamping seat 21, one side of the clamping seat 21 is connected to the connecting belt 1, and two claws 22 are symmetrically provided on the left and right ends of the other side. The shape and size of the two claws 22 match the card slot 41, so that they can be smoothly inserted into the card slot 41 and realize a firm snap connection, that is, the claw 22 is inserted into the card slot 41 of the snap-fit ​​base 4, and the claw 22 and the card slot 41 bite into each other to realize a firm snap connection, thereby fixing the connecting belt 1 and the pull tab 5 together.

[0038] Based on the above embodiment, each claw 22 includes a base 23 and a hook 24. The hook 24 is connected to the clamping seat 21 through the base 23. The clamping member 2 is an elastic member. The length of the base 23 is the same as the thickness of the clamping base 4, so that the hook 24 fits tightly on the upper surface of the clamping base 4, and the base 23 fits tightly on the lower surface of the clamping base 4.

[0039] That is to say, when the clamping member 2 passes through the through hole of the pull tab 5, the hooks 24 on both sides will pass through the corresponding slots 41, and then the hooks 24 will abut against the outer surface of the slot 41 facing the opening. Since the width between the inner edges of the two slots 41 is greater than the opening width formed by the inner sides of the two hooks 24 (i.e. Figure 2 The distance L1 is greater than the distance L2), and the outer surface of the slot 41 facing the opening side will give the hook 24 an outward expansion force, and the two hooks 24 will move away from each other to drive the two bases 23 away. After the two hooks 24 pass through the slot 41 and are located on the upper surface of the engaging base 4, due to the elasticity of the clamping member 2, the two hooks 24 are naturally reset and fit tightly to the upper surface of the engaging base 4. At the same time, the base 23 fits tightly to the lower surface of the engaging base 4. In this way, a firm connection between the clamping member 2 and the engaging base 4 is completed.

[0040] Based on the above embodiment, the clamping seat 21, the base 23 and the hook 24 are an integrated structure.

[0041] Specifically, the clamping seat 21, the base 23 and the hook 24 are integrated, thereby enhancing the structural strength of the entire clamping member 2, and the integrated structural design simplifies the manufacturing process and reduces the number of parts and assembly steps.

[0042] Based on the above embodiment, the outer surface of the slot 41 facing the opening is a slope 42 , the angle between the slope 42 and the bottom surface of the engaging base 4 is an obtuse angle, and the opposite side of the two hooks 24 is set as an arc surface 25 .

[0043] That is to say, the inclined surface 42 serves to guide the hook portion 24 to smoothly enter the slot 41. When the clamping member 2 is pushed from top to bottom toward the locking base 4, the hook portion 24 will first contact the bottom of the inclined surface 42. The opposite side of the two hook portions 24 is set to be an arc surface 25. The arc surface 25 helps to reduce the friction between the hook portion 24 and the slot 41. When the hook portion 24 moves in the slot 41, the arc surface can slide more smoothly, thereby reducing wear and resistance.

[0044] Based on the above embodiment, the side of the hook 24 facing the clamping seat 21 is a limiting surface 26, and the limiting surface 26 is tightly fitted to the upper end surface of the clamping base 4; the limiting surface 26 and the upper end surface of the clamping base 4 are both horizontal surfaces; and anti-slip grooves are provided on the limiting surface 26.

[0045] In other words, both the limiting surface 26 and the upper surface of the engaging base 4 are designed to be horizontal, ensuring more uniform contact between them. Anti-slip grooves are also added to the limiting surface 26. These anti-slip grooves are composed of a series of tiny protrusions or grooves that increase the friction between the limiting surface 26 and the upper surface of the engaging base 4. When external forces attempt to pull the hook 24 out of the engaging slot 41, the anti-slip grooves provide additional resistance, preventing the pull tab from accidentally disengaging.

[0046] On the basis of the above embodiment, the outer surface of the force applying member 3 is provided with anti-skid particles, anti-skid stripes or anti-skid grooves, thereby effectively increasing the friction between the force applying member 3 and the user's hand.

[0047] In addition, the present application also provides a zipper, which includes a pull tab, a slider and a pull piece 5. The pull tab is any of the pull tabs mentioned above. The slider is used to open and close the chain teeth. The pull tab 5 is arranged on the slider. A through hole is provided on the pull tab 5. The connecting belt 1 of the pull tab passes through the through hole and is connected to the pull tab 5.

[0048] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0049] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
