[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] The core of this utility model is to provide a zipper pull with fewer parts, high assembly efficiency, simple process, and low scrap rate of finished products.

[0042] Another core aspect of this invention is to provide a zipper that includes the aforementioned zipper head.

[0043] Please refer to Figure 1 A zipper pull for controlling the closing of a zipper includes a zipper pull body 1 and a zipper tab body 2. The zipper pull body 1 has a connecting shaft 101, and a zipper pull slot 102 is formed between the connecting shaft 101 and the zipper pull. The zipper tab body 2 has an elastic deformation function and includes a pull part 201 and a connecting part 206 located at one end of the zipper tab body 2. The connecting part 206 is bent from the end of the zipper tab body 2. A first preset gap is provided on the side of the connecting part 206 and the pull part 201 near the bending position to form the zipper tab slot 202. When the connecting part 206 passes through the zipper pull slot 102 and the connecting shaft 101 is completely located in the zipper tab slot 202, the zipper tab body 2 and the zipper pull body 1 are rotatably connected along the length of the zipper. The connecting shaft 101 and the zipper tab slot 202 are interference-fitted.

[0044] It should be noted that in this embodiment of the utility model, both the pull head body 1 and the pull tab body 2 can be made of plastic or metal, preferably plastic, and injection molding is used. The handle formed by this method and using this material has higher strength, a simpler production process, and better flexibility.

[0045] In the above embodiments, when the pull sheet body 2 is produced by injection molding, the bending position can be formed at the same time by injection molding, avoiding the need for secondary bending.

[0046] Optionally, in some embodiments, the pull tab body 2 can adopt a strip-shaped structure or rod-shaped structure of any shape, such as a circular or polygonal cross-section, which can be selected according to the clothing design.

[0047] Optionally, in some embodiments, anti-slip textures or anti-slip materials are provided at the contact position between the pull tab slot 202 and the connecting shaft 101, which can further improve the stability after the pull tab and the pull head are connected, and effectively prevent the pull tab from separating from the pull head through the interference fit between the connecting shaft 101 and the pull tab slot 202.

[0048] Optionally, in some embodiments, the side of the pull tab 201 away from the bend is divided into multiple segments, and the multiple segments are arranged at a preset angle. Specifically, there are horizontal segments and connecting segments. The connecting segments are connected to the horizontal end at an obtuse angle so that the distance between the horizontal end and the zipper is smaller than the distance between the bend and the zipper. This reduces the overall distance between the pull tab and the zipper, thereby improving the concealment effect of the pull tab during use.

[0049] In this invention, the zipper head is used to control the closure of the zipper. The zipper head includes a zipper head body 1 and a pull tab body 2. The zipper head body 1 is provided with a connecting shaft 101. The pull tab body 2 has an elastic deformation function. The pull tab body 2 includes a pull part 201 and a connecting part 206 located at one end of the pull tab body 2. The connecting part 206 is formed by bending the end of the pull tab body 2. Bending helps to improve the strength of the pull tab body 2 and reduces the number of processes to improve production efficiency. The connecting part 206 and the pull part 201 are provided with a first preset gap on the side near the bending position for forming a pull tab slot 202. When the connecting part 206 passes through the zipper head slot 102 and the connecting shaft 101 is fully engaged... Within the pull tab slot 202, the pull tab body 2 and the zipper head body 1 are rotatably connected along the length of the zipper. That is, when the zipper head body 1 and the pull tab body 2 are installed, the connecting part 206 passes through the zipper head slot 102 and the connecting shaft 101 is completely located within the pull tab slot 202. At this time, the pull tab body 2 can rotate around the connecting shaft 101, so that the user can operate the zipper head to control the zipper closure. The connecting shaft 101 and the pull tab slot 202 are interference-fitted, which can facilitate the separation of the pull tab body 2 and the zipper head body 1, ensuring the effectiveness of the zipper head, improving the user experience, and reducing the number of parts, resulting in high assembly efficiency, simple process, and low scrap rate of finished products.

[0050] Please refer to Figure 3In some embodiments, the zipper head body 1 is provided with two support protrusions 103, and the connecting shaft 101 is arranged perpendicular to the length of the zipper. The two ends of the connecting shaft 101 are respectively connected to the two support protrusions 103, so that the two support protrusions 103, the connecting shaft 101 and the zipper head body 1 together form the zipper head slot 102. That is, by providing two support protrusions 103 on the zipper head body 1 and fixing the connecting shaft 101 to the two support protrusions 103, the connecting shaft 101 is fixed, and the two support protrusions 103, the connecting shaft 101 and the zipper head body 1 together form the zipper head slot 102.

[0051] Optionally, in some embodiments, the two support protrusions 103 and the connecting shaft 101 are integrally formed with the slider body 1.

[0052] Optionally, in some embodiments, the shape and structure of the support protrusion 103 can be determined according to the specific style of the clothing, as long as it cooperates with the connecting shaft 101 to form the pull head slot 102.

[0053] Please refer to Figure 5 In some embodiments, the cross-section of the connecting shaft 101 is a polygonal structure, and the shape of the pull tab slot 202 is similar to that of the connecting shaft 101, so that when the pull tab body 2 is in a position parallel to the length direction of the zipper, the connecting shaft 101 has the function of restricting the pull tab body 2 to be in that position. That is, by setting the connecting shaft 101 as a polygonal structure, and through the interference fit between the pull tab slot 202 and the connecting shaft 101, the connecting shaft 101 has the function of restricting the free rotation of the pull tab body 2, which is beneficial to keep the pull tab body 2 fixed when in use and prevent it from shaking when it moves with the user.

[0054] Optionally, in some embodiments, the cross-section of the connecting shaft 101 is rectangular and parallel to the length direction of the zipper. The shape of the pull tab slot 202 along the direction parallel to the cross-section is also rectangular. Therefore, the connecting shaft 101 has the function of restricting the free rotation of the pull tab body 2. When the pull tab body 2 rotates, it will have the rotation function due to the elastic deformation generated by the pull tab body 2.

[0055] In the above embodiment, the connecting shaft 101 with a rectangular cross-section has its long side parallel to the length direction of the zipper, while its short side is perpendicular to the length of the zipper. Therefore, when the zipper body 2 is in a position parallel to the length direction of the zipper, the connecting shaft 101 restricts the zipper body 2 to be in a position parallel to the length direction of the zipper, so as to ensure that the zipper body 2 is close to the user's clothing, thereby improving its aesthetics and concealment.

[0056] Please refer to Figure 6In some embodiments, the pull tab body 2 further includes a limiting part 203, which is located on the side of the connecting part 206 away from the bending point of the pull tab body 2. The limiting part 203 is a protruding structure so that the distance between the limiting part 203 and the pull part 201 is smaller than the distance between the connecting part 206 and the pull part 201. That is, by providing a limiting part 203 on one side of the connecting part 206, the protruding limiting part 203 can limit the position after the connecting shaft 101 enters the pull tab slot 202, which can further prevent the pull tab body 2 from separating from the pull head body 1.

[0057] In the above embodiment, the limiting part 203 is a protruding structure that is inclined toward the pull tab groove 202. That is, the inclination angle of the limiting part 203 toward the pull tab groove 202 is close to 90 degrees, so as to further increase the limiting effect on the pull tab body 2.

[0058] Optionally, in some embodiments, in order to further prevent the pull tab body 2 from detaching from the pull head body 1, the limiting part 203 and the pull part 201 are connected. That is, after the connecting shaft 101 enters the pull tab slot 202, the limiting part 203 and the pull part 201 remain connected, so that the pull tab slot 202 becomes a closed structure, thereby further improving the firmness of the connection between the pull tab body 2 and the pull head body 1.

[0059] Please refer to Figure 7 In some embodiments, the pull tab body 2 further includes an entry portion 205. The entry portion 205 is provided on the side of the connecting portion 206 and the pull portion 201 away from the bending position. A second preset gap is provided between the entry portion 205 and the pull portion 201. The maximum width of the second preset gap is less than the minimum width of the first preset gap. That is, in order to facilitate the user to smoothly insert the connecting portion 206 into the pull tab slot 102, an entry portion 205 is provided on one side of the connecting portion 206. The entry portion 205 can facilitate the insertion of the connecting portion 206 into the pull tab slot 102.

[0060] Optionally, in some embodiments, the width of the end of the inlet 205 away from the connecting part 206 gradually decreases so that the connecting part 206 can be quickly inserted into the pull head slot 102 during installation.

[0061] Optionally, in some embodiments, the thickness of the end of the inlet 205 away from the connecting part 206 gradually decreases so that the connecting part 206 can be quickly inserted into the pull head slot 102 during installation.

[0062] Optionally, in some embodiments, the limiting part 203 is located between the connecting part 206 and the entering part 205, and the limiting part 203 and the entering part 205 are smoothly connected to further improve the smoothness of the connecting shaft 101 entering the pull tab groove 202.

[0063] Optionally, in some embodiments, the minimum distance between the limiting part 203 and the pull part 201 is the same as the second preset gap. By limiting the width of the second preset gap, that is, increasing the distance to the limiting position of the connecting shaft 101, the limiting effect on the position of the connecting shaft 101 is improved.

[0064] Optionally, in some embodiments, a plurality of anti-detachment components are evenly arranged on the side of the entry portion 205 near the handle portion 201. The anti-detachment components are used to prevent the handle body and the pull head body 1 from separating.

[0065] In the above embodiment, the anti-detachment component is a barbed structure, specifically, it consists of several evenly distributed barbed protrusions, and the inclination direction of the barbed protrusions is the same as the direction in which the connecting shaft 101 enters the pull tab groove 202.

[0066] Please refer to Figure 7 In some embodiments, the pull tab body 2 further includes a bending groove 204. The bending groove 204 is a strip-shaped groove and is arranged perpendicular to the length direction of the zipper. The bending groove 204 is located between the connecting part 206 and the entry part 205, and is located on the side away from the pull part 201. The bending groove 204 is used to make the connecting part 206 and the entry part 205 more easily deformable. When the connecting shaft 101 enters the pull tab groove hole 202 through the entry part 205, the thickness of the connecting shaft 101 is greater than the second gap. Therefore, the bending groove 204 can make the entry part 205 more easily deformable, thereby improving the smoothness of the assembly of the pull tab body 2 and the zipper head body 1.

[0067] Optionally, in some embodiments, the cross-section of the bending groove 204 is an arc shape, a U-shape, or a V-shape.

[0068] Optionally, in some embodiments, the width of the bending groove 204 can be determined according to the requirements of actual use.

[0069] Please refer to Figure 7 In some embodiments, the pull tab body 2 has an arc structure with an opening facing away from the pull head body 1 at the side near the bend and the contact position with the pull head body 1. The arc structure is used to make the pull tab body 2 rotate more smoothly and improve the user experience.

[0070] Please refer to Figure 7 In some embodiments, the pull tab body 2 also includes an anti-slip part 207. The anti-slip part 207 is located on the side of the pull part 201 away from the bend of the pull tab body 2 and on the side of the pull part 201 close to the pull head body 1. The anti-slip part 207 helps to improve the user's operating experience when pulling the pull head and prevents the fingers from slipping.

[0071] Optionally, in some embodiments, the anti-slip portion 207 is a plurality of protrusions provided on the handle portion 201, and the protrusions may be strip-shaped protrusions or dot-shaped protrusions.

[0072] A zipper comprising the zipper pull described in any of the preceding claims.

[0073] In other words, the key point of this utility model is that the pull tab body 2 has an elastic deformation function. The pull tab body 2 includes a pull part 201 and a connecting part 206 located at one end of the pull tab body 2. The connecting part 206 is formed by bending the end of the pull tab body 2. Bending helps to improve the strength of the pull tab body 2 and reduce the number of processes to improve production efficiency. The connecting part 206 and the pull part 201 are provided with a first preset gap on the side near the bending position for forming the pull tab groove 202. When the connecting part 206 passes through the pull head groove 102 and the connecting shaft 101 is completely located in the pull tab groove 202, it is used to make the pull tab body 2... The zipper head body 1 is rotatably connected to the zipper body 2 along the length of the zipper. That is, when the zipper head body 1 and the zipper body 2 are installed, the connecting part 206 passes through the zipper head slot 102 and the connecting shaft 101 is completely located in the zipper slot 202. At this time, the zipper body 2 can rotate around the connecting shaft 101 to facilitate the user to operate the zipper head to control the zipper closure. The connecting shaft 101 and the zipper slot 202 are interference-fitted, which can facilitate the detachment of the zipper body 2 from the zipper head body 1 to ensure the zipper head's performance and improve the user experience. In addition, the number of parts is small, the assembly efficiency is high, the process is simple, and the scrap rate of finished products is low.
