[0029] As described in the background, with the development of the clothing, luggage and other industries, the requirements for the zipper puller are also getting higher and higher. In the fashion field, consumers not only pay attention to the practicability of the product, but also pay attention to its appearance design. This has prompted the zipper puller to change from a purely functional part to a part with decoration. For example, in high-end fashion design, the design of the puller needs to match the overall style of the clothing, and may require the puller to use special materials (such as precious metals, crystals, etc.) to improve the grade of the clothing. In terms of functionality, for some special purpose zippers, such as outdoor equipment, industrial products, the puller needs to have better anti-slip performance. Because in outdoor environment or industrial operation, the user may wear gloves to operate, and ordinary puller is difficult to pull in this case. Therefore, it is necessary to design a puller with anti-slip texture or special shape to facilitate easy operation of the zipper when wearing gloves. However, the holding part of the existing puller cannot be separated and replaced from the connecting part, and the user experience is poor.

[0030] Referring to Figures 1 to 4To solve the above problems, according to one aspect of the present application, the embodiment of the present application provides a pull tab, which is used for connecting with a puller of a zipper, and the pull tab comprises a connecting part 10 and a pull tab part 20, wherein the connecting part 10 comprises a connecting main body 11 and an elastic main body 12, the elastic main body 12 is arranged on the connecting main body 11, the connecting main body 11 is provided with a connecting structure 111, the connecting main body 11 is connected with the puller through the connecting structure 111, and the elastic main body 12 is provided with an embedded cavity 121; the pull tab part 20 comprises a pull tab main body 21 and an embedded main body 22, the embedded main body 22 is arranged on the pull tab main body 21, the embedded cavity 121 is provided with a first embedded structure, the embedded main body 22 is provided with a second embedded structure, the embedded main body 22 can be arranged in the embedded cavity 121, and the embedded main body 22 is detachably embedded in the embedded cavity 121 through elastic deformation of the elastic main body 12 and cooperation of the first embedded structure and the second embedded structure. The pull tab provided by the embodiment is connected with the puller of the zipper through the connecting structure 111 arranged on the connecting main body 11. Meanwhile, the pull tab provided by the embodiment is provided with the embedded cavity 121 on the elastic main body 12, the first embedded structure is arranged in the embedded cavity 121, the embedded main body 22 is arranged on the pull tab main body 21, and the second embedded structure is arranged on the embedded main body 22, so that the embedded cavity 121 and the embedded main body 22 can be embedded through cooperation of the first embedded structure and the second embedded structure, and the pull tab part 20 can be stably installed on the connecting part 10. Since the elastic main body 12 provided with the embedded cavity 121 has a certain elastic deformation capacity, the embedded main body 22 can be smoothly arranged in the embedded cavity 121 and stably embedded by exerting a certain insertion force on the pull tab part 20 during embedding of the embedded main body 22 and the embedded cavity 121. When the pull tab part 20 needs to be removed, an external force greater than a predetermined separation threshold value is exerted on the pull tab part 20 to overcome the friction and interaction force between the embedded main body 22 and the embedded cavity 121, so that the embedded main body 22 is separated from the embedded cavity 121, thereby achieving removal of the pull tab part 20. Since the pull tab part 20 can be separated from the connecting part 10, users can replace the pull tab part 20 with different appearances according to different occasions, seasons or personal preferences, thereby improving the use experience.

[0031] In an alternative embodiment, the embedded cavity 121 provided by the embodiment is located on a side of the elastic main body 12 away from the connecting main body 11 and communicates with a side wall of the side of the elastic main body 12 away from the connecting main body 11.

[0032] In a specific embodiment, the connecting structure 111 provided by the embodiment is a conventional structure in the prior art, which will not be described herein.

[0033] Referring to Figure 2 and Figure 3As shown, in a specific embodiment, a first fitting structure is arranged in the fitting cavity 121, and a second fitting structure is arranged on the fitting body 22, so that the fitting body 22 can be fitted with the fitting cavity 121 by cooperation of the first fitting structure and the second fitting structure when the fitting body 22 is arranged in the fitting cavity 121. Through cooperation of the first fitting structure and the second fitting structure, the fitting cavity 121 and the fitting body 22 can be accurately positioned during fitting, ensuring the accuracy of the fitting position. In addition, the existence of the first fitting structure and the second fitting structure can make the connection between the elastic body 12 and the fitting body 22 more closely, so that the pull tab is more stable during pulling and does not shake and make noise.

[0034] As shown in Figure 2 and Figure 3 As shown, in a specific embodiment, one of the first fitting structure and the second fitting structure in the embodiment includes a fitting protrusion 1211, and the other of the first fitting structure and the second fitting structure includes a fitting recess 221. The fitting protrusion 1211 is adapted to the fitting recess 221. When the fitting body 22 is arranged in the fitting cavity 121, the fitting protrusion 1211 and the fitting recess 221 are in abutting cooperation to fit the fitting body 22 with the fitting cavity 121. One of the first fitting structure and the second fitting structure is arranged to include the fitting protrusion 1211, and the other of the first fitting structure and the second fitting structure is arranged to include the fitting recess 221. At the same time, the fitting protrusion 1211 is arranged to be adapted to the fitting recess 221. When the fitting body 22 is arranged in the fitting cavity 121, the fitting body 22 can be fitted with the fitting cavity 121 by cooperation of the fitting protrusion 1211 and the fitting recess 221. Through cooperation of the fitting protrusion 1211 and the fitting recess 221, the fitting cavity 121 and the fitting body 22 can be accurately positioned during fitting, ensuring the accuracy of the fitting position. In addition, the existence of the fitting protrusion 1211 and the fitting recess 221 can make the connection between the elastic body 12 and the fitting body 22 more closely, so that the pull tab is more stable during pulling and does not shake and make noise.

[0035] In a specific embodiment, when the fitting body 22 is fitted with the fitting cavity 121, the projection of the fitting recess 221 in the extension direction of the fitting body 22 at least partially overlaps the projection of the fitting protrusion 1211 in the extension direction of the fitting body 22.

[0036] As shown in Figure 2As shown, in a specific embodiment, the first fitting structure in the present embodiment includes a plurality of fitting protrusions 1211, the second fitting structure includes a plurality of fitting recesses 221, the fitting cavity 121 has two opposite side walls in the first direction, the plurality of fitting protrusions 1211 are respectively arranged on the two opposite side walls of the fitting cavity 121 in the first direction, the fitting main body 22 has two opposite side walls in the first direction, and the plurality of fitting recesses 221 are respectively arranged on the two opposite side walls of the fitting main body 22 in the first direction, wherein the first direction is perpendicular to the thickness direction of the pull-tab main body 21 and the extension direction of the pull-tab main body 21; when the fitting main body 22 is inserted into the fitting cavity 121, the plurality of fitting protrusions 1211 correspond to the plurality of fitting recesses 221 one by one, the fitting protrusion 1211 and the corresponding fitting recess 221 are in abutting fit, so that the fitting main body 22 and the fitting cavity 121 are fitted. Through the abutting fit of the plurality of fitting protrusions 1211 and the plurality of fitting recesses 221, the connection strength between the elastic main body 12 and the fitting main body 22 can be effectively improved. Since the plurality of fitting protrusions 1211 are respectively arranged on the two opposite side walls of the fitting cavity 121 in the first direction, and the plurality of fitting recesses 221 are respectively arranged on the two opposite side walls of the fitting main body 22 in the first direction, multi-directional fixation can be provided. When the pull-tab is subjected to lateral tension, torsion or complex combined external force, the plurality of fitting points can work cooperatively to effectively prevent the pull-tab part 20 from being displaced or detached from the connecting part 10. At the same time, the existence of the plurality of fitting protrusions 1211 and the plurality of fitting recesses 221 can uniformly distribute the external forces such as tension and pressure received by the pull-tab during use on each fitting point, thereby avoiding damage to the fitting protrusion 1211 and / or the fitting recess 221 due to excessive local stress, thereby prolonging the service life of the pull-tab. Since the external force is dispersed to the plurality of fitting points, the friction and wear of each fitting protrusion 1211 and fitting recess 221 are relatively small. During frequent use of the pull-tab, the local wear rate of the fitting part can be reduced, and the possibility of fitting failure due to wear can be reduced.

[0037] Referring to Figure 2In a specific embodiment, as shown, at least two of the plurality of fitting protrusions 1211 in the present embodiment are mirror images of each other along the middle section of the fitting cavity 121 in the first direction, and at least two of the plurality of fitting recesses 221 are mirror images of each other along the middle section of the fitting body 22 in the first direction. By arranging at least two of the plurality of fitting protrusions 1211 as mirror images of each other along the middle section of the fitting cavity 121 in the first direction, and at least two of the plurality of fitting recesses 221 as mirror images of each other along the middle section of the fitting body 22 in the first direction, the operator can be provided with more intuitive guidance during the assembly of the connecting portion 10 and the pull-tab portion 20, which facilitates the operator to determine the accuracy of the assembly direction and position. In addition, when the fitting body 22 is inserted into the fitting cavity 121, the symmetry of the layout makes the fitting process on the left and right sides similar and repetitive, which reduces the difficulty of assembly, thereby improving the precision and speed of assembly, and effectively reducing the assembly time and error rate, especially in mass production.

[0038] Referring to Figure 2 In a specific embodiment, as shown, the first fitting structure in the present embodiment includes a fitting protrusion 1211 arranged on the inner side wall of the fitting cavity 121, and a first inclined surface 12111 arranged on the side of the fitting protrusion 1211 close to the pull-tab body 21, which is inclined towards the side close to the middle of the fitting cavity 121 in the direction from the first end of the elastic body 12 to the second end of the elastic body 12. The first end of the elastic body 12 close to the pull-tab body 21 is the first end of the elastic body 12, and the second end of the elastic body 12 away from the pull-tab body 21 is the second end of the elastic body 12. The first inclined surface 12111 arranged on the side of the fitting protrusion 1211 close to the pull-tab body 21 is inclined towards the side close to the middle of the fitting cavity 121 in the direction from the first end of the elastic body 12 to the second end of the elastic body 12, which allows the elastic body 12 to guide the insertion of the fitting body 22 during the process of inserting the fitting body 22 into the fitting cavity 121, so that the fitting body 22 can be more easily aligned with the fitting protrusion 1211 and start the fitting process, thereby improving the convenience and efficiency of assembly. Due to the presence of the first inclined surface 12111, the requirements for the angle and position of the insertion of the fitting body 22 during assembly are relatively reduced. Even if there is a certain deviation during the insertion process, the first inclined surface 12111 can guide the fitting body 22 to automatically adjust the position so that it is correctly matched with the fitting protrusion 1211, which means that the operating skill requirements of the assembly personnel can be appropriately reduced, and the rate of defective products due to improper assembly can be reduced.

[0039] Referring to Figure 2As shown in the figure, in a specific embodiment, the first fitting structure in the embodiment includes a fitting protrusion 1211 arranged on the inner side wall of the fitting cavity 121, and a second inclined surface 12112 is arranged on the side of the fitting protrusion 1211 away from the pull-tab body 21, which is inclined to the side close to the middle of the fitting cavity 121 in the direction from the second end of the elastic body 12 to the first end of the elastic body 12. The end of the elastic body 12 close to the pull-tab body 21 is the first end of the elastic body 12, and the end of the elastic body 12 away from the pull-tab body 21 is the second end of the elastic body 12. The second inclined surface 12112 arranged on the side of the fitting protrusion 1211 away from the pull-tab body 21 in the direction from the second end of the elastic body 12 to the first end of the elastic body 12 and inclined to the side close to the middle of the fitting cavity 121 can disperse the disassembly force of the fitting body 22 to a certain extent. In the disassembly process of the fitting body 22, directly applying force to separate the fitting body 22 from the fitting protrusion 1211 may generate a large local stress. The second inclined surface 12112 can disperse this disassembly force to the inclined surface, so that the stress is more evenly distributed, thereby reducing the wear of the fitting protrusion 1211 and the fitting body 22 in the disassembly process.

[0040] Referring to Figure 2 and Figure 3 As shown in the figure, in a specific embodiment, the first fitting structure in the embodiment includes a fitting protrusion 1211 arranged on the inner side wall of the fitting cavity 121, and a second inclined surface 12112 is arranged on the side of the fitting protrusion 1211 away from the pull-tab body 21, which is inclined to the side close to the middle of the fitting cavity 121 in the direction from the second end of the elastic body 12 to the first end of the elastic body 12. The end of the elastic body 12 close to the pull-tab body 21 is the first end of the elastic body 12, and the end of the elastic body 12 away from the pull-tab body 21 is the second end of the elastic body 12. The second inclined surface 12112 arranged on the side of the fitting protrusion 1211 away from the pull-tab body 21 in the direction from the second end of the elastic body 12 to the first end of the elastic body 12 and inclined to the side close to the middle of the fitting cavity 121 can disperse the disassembly force of the fitting body 22 to a certain extent. In the disassembly process of the fitting body 22, directly applying force to separate the fitting body 22 from the fitting protrusion 1211 may generate a large local stress. The second inclined surface 12112 can disperse this disassembly force to the inclined surface, so that the stress is more evenly distributed, thereby reducing the wear of the fitting protrusion 1211 and the fitting body 22 in the disassembly process.

[0041] In an optional embodiment, the guide surface 2211 provided in the embodiment is an inclined surface inclined to the side close to the middle of the fitting body 22 in the direction from the first end of the fitting body 22 to the second end of the fitting body 22. Arranging the guide surface 2211 as an inclined surface can guide the elastic deformation of the fitting protrusion 1211 in the disassembly process of the fitting body 22, thereby reducing the resistance of the fitting protrusion 1211 and the fitting body 22 in the disassembly process.

[0042] In another embodiment, the guide surface 2211 is a curved surface gradually protruding from the two sides of the fitting body in the thickness direction to the middle of the fitting body in the thickness direction, and the extension direction of the guide surface 2211 is inclined to the side close to the middle of the fitting body 22 in the direction from the first end of the fitting body 22 to the second end of the fitting body 22. By setting the guide surface 2211 as a curved surface that protrudes outward, the fitting area of the guide surface and the fitting protrusion can be reduced while guiding the elastic deformation of the fitting protrusion 1211, thereby reducing the resistance of the fitting protrusion 1211 and the fitting body 22 during disassembly. Of course, in other embodiments, the guide surface 2211 provided by the present embodiment can also be other structures that can guide the elastic deformation of the fitting protrusion 1211 to reduce the resistance of the fitting protrusion 1211 during disassembly.

[0043] Referring to Figure 3 In a specific embodiment, the side of the fitting body 22 close to the elastic body 12 is provided with a guide protrusion that gradually protrudes away from the fitting body 22 from the two sides of the fitting body 22 in the first direction to the middle of the fitting body 22 in the first direction, for guiding the movement of the fitting body 22 during the fitting of the fitting body 22 and the fitting cavity 121. The guide protrusion that gradually protrudes away from the fitting body 22 from the two sides of the fitting body 22 in the first direction to the middle of the fitting body 22 in the first direction can guide the insertion of the fitting body 22, making it easier for the fitting body 22 to align with the fitting cavity and start the fitting process, thereby improving the convenience and efficiency of assembly.

[0044] Referring to Figure 4 In a specific embodiment, the end of the elastic body 12 close to the pull-tab body 21 is provided with a receiving groove 122, and the pull-tab body 21 can be at least partially received in the receiving groove 122 when the fitting body 22 is fitted with the fitting cavity 121. By providing the receiving groove 122 at the end of the elastic body 12 close to the pull-tab body 21, the pull-tab body 21 can be at least partially received in the receiving groove 122 when the fitting body 22 is fitted with the fitting cavity 121, thereby improving the integrity of the pull-tab, and the receiving groove 122 can also limit the pull-tab body 21 to some extent, thereby improving the connection reliability between the pull-tab portion 20 and the connecting portion 10.

[0045] In an optional embodiment, the elastic body 12 provided by the present embodiment is fixedly connected with the connecting body 11 by pressure bonding.

[0054] In summary, the pull tab and the zipper provided by the embodiment have at least the following beneficial technical effects: the pull tab provided by the embodiment is connected with the puller of the zipper through the connecting structure 111 arranged on the connecting body 11, and the pull tab is installed on the connecting part 10 through the embedding cavity 121 arranged on the elastic body 12 and the embedding body 22 arranged on the pull tab body 21, so that the pull tab part 20 is stably embedded. Since the elastic body 12 with the embedding cavity 121 has a certain elastic deformation capacity, the embedding body 22 can smoothly enter the embedding cavity 121 and be stably embedded by exerting a certain insertion force on the pull tab part 20 during the embedding of the embedding body 22 and the embedding cavity 121. When the pull tab part 20 needs to be removed, an external force greater than a predetermined separation threshold is exerted on the pull tab part 20 to overcome the friction and interaction between the embedding body 22 and the embedding cavity 121, so that the embedding body 22 is separated from the embedding cavity 121, thereby achieving the removal of the pull tab part 20. Since the pull tab part 20 can be separated and replaced from the connecting part 10, the user can replace the pull tab part 20 with different appearances according to different occasions, seasons or personal preferences, thereby improving the user experience.

[0055] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
