Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a zipper puller with a puller auxiliary device that can be rotatably assembled and disassembled, and a zipper pull head comprising the zipper puller. Background Art

[0002] Currently, zippers are widely used in daily necessities such as clothing, bags, tents, bedding, etc., and are used to merge or separate items.

[0003] Typically, a zipper consists of a pair of fabric tapes, a chain tether secured to the inner edges of each tape, and a slider. The slider includes a slider body mounted on the chain tethers and a pull tab mounted on the surface of the slider body. By holding the pull tab and pulling the slider body along the length of the zipper, the pair of chain tethers engage or disengage, thereby closing or opening the zipper accordingly. To enhance the design of the zipper, some existing zippers are equipped with a pull tab assistor, which is detachably attached to the pull tab of the zipper slider. This assistor not only makes pulling the slider easier but also enhances the design of the zipper.

[0004] For example, the Chinese utility model patent with authorization publication number CN217446885U discloses a split, modular pull tab that achieves a detachable connection between the rear and front pull tabs by snapping a connecting post on the rear pull tab into a connecting hole on the front pull tab. However, the outer diameter of the end of the connecting post on the rear pull tab is much larger than the diameter of the connecting hole, requiring considerable force to press the connecting post into the hole, making the installation operation difficult.

[0005] For example, in the zipper pull disclosed in Chinese invention patent publication number CN110811084B, when installing the pull-tab auxiliary device, the pull-tab auxiliary portion of the pull-tab auxiliary device is passed through the mounting hole on the pull-tab body, and the neck of one end of the pull-tab auxiliary portion is retained in the mounting hole of the pull-tab body by a head limiter. Although this makes installation of the pull-tab auxiliary device relatively easy, the pull-tab auxiliary portion needs to be passed through the mounting hole during installation. The other end of the pull-tab auxiliary portion, away from the neck, serves as the grip portion. As a result, the shape of the grip portion is restricted by the mounting hole on the pull-tab body, making it difficult to design a more diverse shape of the grip portion, which in turn limits the appearance of the pull-tab auxiliary device. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a zipper pull tab with a pull tab auxiliary device that can be rotatably assembled and disassembled, which not only facilitates the installation of the pull tab auxiliary device but also does not restrict the appearance design of the pull tab auxiliary device.

[0007] To achieve the above-mentioned object, the present invention provides a zipper pull tab with a pull tab auxiliary device for rotary assembly and disassembly, comprising a pull tab body and a pull tab auxiliary device, wherein the pull tab body is provided with a through mounting hole and an appliance mounting portion distributed around the mounting hole, the pull tab auxiliary device comprising an appliance body, an appliance column extending from the appliance body, and an appliance head fixed to the outer end of the appliance column, the appliance head being an elastically deformable body, the mounting hole having different apertures in at least two intersecting directions, the appliance head having different lengths in at least two intersecting directions, and the appliance column being rotatably received in the mounting hole;

[0008] When the length direction of the tool head is consistent with the length direction of the mounting hole, the mounting hole allows the elastically deformable tool head to pass through;

[0009] When the pull-tab assistant with the tool head having passed through the mounting hole rotates until the length direction of the tool head intersects with the length direction of the mounting hole, the tool head abuts against the tool mounting portion.

[0010] In the present application, both the mounting hole and the tool head are configured as non-circular structures, meaning that the mounting hole has different diameters in at least two intersecting directions, and the tool head has different lengths in at least two intersecting directions. Thus, the mounting hole has a larger diameter in its longitudinal direction, and the tool head has a larger length in its longitudinal direction. Thus, when the longitudinal direction of the tool head aligns with the longitudinal direction of the mounting hole, the tool head can be easily and conveniently pressed into the mounting hole, allowing it to pass through the mounting hole, thanks to the elastic deformation characteristics of the tool head. The pull-tab auxiliary device is then rotated at an angle so that the longitudinal direction of the tool head intersects with the longitudinal direction of the mounting hole. At this point, the tool head abuts against the tool mounting portion, preventing it from escaping from the mounting hole, thereby reliably connecting the pull-tab auxiliary device to the pull-tab body. Therefore, the operation of pressing the head of the device into the mounting hole in this application is very easy, which not only facilitates the installation and replacement of the pull-tab assistant, but also does not cause any constraints or restrictions on the device body caused by the mounting hole, and also does not limit the appearance design of the pull-tab assistant, so that this application can use pull-tab assistants of any appearance, greatly improving and enriching the design of the zipper pull tab, and ultimately improving and enriching the design sense of the zipper.

[0011] Furthermore, the setting structure of the mounting hole on the pull-tab body is preferably: the mounting hole is a waist-shaped hole or a rectangular hole, and the mounting hole extends straight along the width direction of the pull-tab body, that is, the length direction of the mounting hole is consistent with the width direction of the pull-tab body; and the mounting hole passes through the pull-tab body along the thickness direction of the pull-tab body.

[0012] Preferably, based on the waist-shaped hole structure or rectangular hole structure of the mounting hole, the hole wall of the mounting hole has a pair of transverse straight hole walls extending along the width direction of the pull-tab body; when the length direction of the device head is consistent with the length direction of the mounting hole, and the device head has passed through the mounting hole, there is a gap between the outer peripheral surface of the device column and the pair of transverse straight hole walls of the mounting hole, thereby facilitating the subsequent rotation of the pull-tab auxiliary device, and also facilitating the installation operation of the pull-tab auxiliary device.

[0013] Furthermore, the length directions of the tool head, the tool body, and the pull-tab body are all aligned. After the tool head is pressed through the mounting hole, the pull-tab auxiliary device is rotated until its length aligns with the length of the pull-tab body. This allows the tool head to abut against the surface of the tool mounting portion, improving the connection reliability between the pull-tab auxiliary device and the pull-tab body. Furthermore, in this state, the tool body of the pull-tab auxiliary device extends along the length of the pull-tab body, resulting in a highly consistent overall appearance of the zipper pull, which helps improve the integrity of the zipper pull and, consequently, its aesthetic appearance.

[0014] Furthermore, the instrument head has a first protrusion extending outward from the instrument column along the length direction of the instrument body, and a second protrusion extending outward from the instrument column along the width direction of the instrument body, and the protruding length of the first protrusion is greater than the protruding length of the second protrusion; when the length direction of the instrument head intersects with the length direction of the mounting hole, the first protrusion abuts against the instrument mounting portion, thereby reliably preventing the instrument head from detaching from the mounting hole.

[0015] Furthermore, the pull-tab body has a first fixing groove and a second fixing groove formed on the surface of the appliance mounting portion. The first fixing groove and the second fixing groove are distributed on both sides of the mounting hole along the length direction of the pull-tab body. When the pull-tab auxiliary device, with the appliance head having passed through the mounting hole, is rotated until the length direction of the appliance head aligns with the length direction of the pull-tab body, the length direction of the appliance head intersects the length direction of the mounting hole, and the two first protrusions at both ends of the appliance head in the length direction respectively engage in the first fixing groove and the second fixing groove. In this way, after the pull-tab auxiliary device is installed, the mating structure in which the two first protrusions respectively engage in the first fixing groove and the second fixing groove reliably restricts the arbitrary rotation and disengagement of the appliance head, thereby restricting the arbitrary rotation and disengagement of the pull-tab auxiliary device, thereby improving the installation reliability of the pull-tab auxiliary device.

[0016] Preferably, the pull-tab body is fixed with at least one first fixing buckle on the surface of the appliance mounting portion, and the first fixing buckle protrudes from the appliance mounting portion along the thickness direction of the pull-tab body, and the first fixing buckle is distributed on the outer peripheral side of the first fixing groove and / or the second fixing groove; when the length direction of the appliance head is consistent with the length direction of the pull-tab body, the first fixing buckle abuts against the outer peripheral side of the appliance head, thereby further improving the installation reliability of the pull-tab auxiliary device.

[0017] Preferably, the two first protrusions at both ends of the tool head are an outer protrusion and an inner protrusion, respectively. The groove wall profile of the first fixing groove matches the outer peripheral profile of the outer protrusion and both are semicircular. The length of the inner protrusion is greater than that of the second fixing groove, and the second fixing groove extends through the outer edge of the tool mounting portion along the length direction of the pull-tab body. When the length direction of the tool head aligns with the length direction of the pull-tab body, the outer protrusion snaps into the first fixing groove, and the inner protrusion snaps into the second fixing groove, with a portion of the inner protrusion extending outward from the pull-tab body. When removing the pull-tab auxiliary device, the semicircular first fixing groove and the outer protrusion facilitate the outer protrusion to be rotated out of the first fixing groove, thereby facilitating the removal of the pull-tab auxiliary device. At the same time, the second fixing groove, which penetrates the structure at both ends, is easy to machine.

[0018] Furthermore, the pull-tab body is provided with a second fixing buckle protruding along the thickness direction of the pull-tab body on the surface of the appliance mounting portion. A pair of third fixing slots are formed in the second fixing buckle. The pair of third fixing slots are formed on the surface of the appliance mounting portion and are distributed on both sides of the mounting hole along the length direction of the pull-tab body. When the pull-tab auxiliary device, with the appliance head having passed through the mounting hole, is rotated until the length direction of the appliance head aligns with the length direction of the pull-tab body, the length direction of the appliance head intersects the length direction of the mounting hole, and the two first protrusions at both ends of the appliance head in the length direction respectively engage in the pair of third fixing slots. In this way, the snap-fitting cooperation between the first protrusions and the third fixing slots effectively improves the reliability and stability of the pull-tab auxiliary device installed in the pull-tab body, and reliably prevents the pull-tab auxiliary device from accidentally detaching from the pull-tab body.

[0019] Preferably, the third fixing groove has at least one first inclined groove wall, which extends obliquely, moving closer to the central axis of the pull-tab body as it moves away from the mounting hole. The outer periphery of the first protrusion has at least one inclined surface. When the first protrusion is engaged in the third fixing groove, the inclination direction of the inclined surface aligns with that of the first inclined groove wall, and the two abut and cooperate, thereby limiting the first protrusion from swinging across the width of the pull-tab body. Furthermore, when the pull-tab auxiliary device is detached from the pull-tab body, the inclined first inclined groove wall facilitates the first protrusion's rotation out of the third fixing groove, thereby facilitating removal of the pull-tab auxiliary device.

[0020] Furthermore, the outer peripheral surface of the outer end of the tool head is provided with an installation guide bevel, which extends in an inclined manner such that the further away from the tool column, the closer to the central axis of the tool head. In this way, when installing the pull-tab assist device, the inclined installation guide bevel facilitates the tool head to be pressed through the installation hole, further facilitating the installation operation of the pull-tab assist device.

[0021] Furthermore, the pull-tab body is a metal part with an integrated structure, so the pull-tab body has good structural strength and is durable. At the same time, the pull-tab auxiliary device is a plastic part with an integrated structure, which is easy to manufacture and has low cost. It is easy to design a variety of pull-tab auxiliary devices with different shapes and colors at low cost. Combined with the detachable structure of the pull-tab auxiliary device on the pull-tab body, it is convenient for users to replace different pull-tab auxiliary devices, thereby enriching the design sense of the zipper.

[0022] The utility model also provides a zipper pull head, comprising a pull head body and the zipper pull tab as described above, wherein the pull tab body is connected to the pull head body.

[0023] As described above, the zipper puller and zipper head of the puller auxiliary device of the present invention have the following features:

[0024] Beneficial effects:

[0025] In the present application, both the mounting hole and the tool head are configured as non-circular shapes, and their profiles are adapted to each other. Thus, when the length of the tool head aligns with the length of the mounting hole, the tool head can be easily and conveniently pressed into the mounting hole, allowing it to pass through the mounting hole with ease. The pull-tab assist device is then rotated at an angle, and the tool head abuts against the tool mounting portion, restricting the tool head from escaping from the mounting hole, thereby reliably connecting the pull-tab assist device to the pull-tab body. Therefore, in the present application, the operation of pressing the tool head into the mounting hole is very easy, facilitating the installation and replacement of the pull-tab assist device without restricting the mounting hole from restricting the tool body, thereby eliminating any restrictions on the pull-tab assist device's external design. This allows the present application to utilize pull-tab assist devices of any external shape, significantly enhancing and enriching the design of the zipper pull tab, and ultimately enhancing and enriching the design of the zipper.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or indirectly connected to the other element through an intervening element.

[0068] In addition, the descriptions of "first", "second", etc. in this application are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0069] The present application relates to the field of zipper technology. For ease of description, in the following embodiments, the various directions are defined as follows: the length of the zipper is defined as the front-to-back direction, the width of the zipper is defined as the left-to-right direction, and the thickness of the zipper is defined as the up-down direction. A zipper primarily comprises a pair of fabric tapes arranged side by side, a chain tether secured to the inner edges of each fabric tape and extending forward and backward, and a zipper pull, which is mounted on the chain tether in a manner that allows for forward and backward sliding. When the zipper pull moves forward, the chain tethers engage, thereby closing the zipper; when the zipper pull moves backward, the chain tethers separate, thereby opening the zipper.

[0070] The utility model mainly relates to a zipper puller and a zipper tab for the zipper puller. The length, width and thickness directions of the zipper puller correspond to the length, width and thickness directions of the zipper, and the length, width and thickness directions of the zipper tab also correspond to the length, width and thickness directions of the zipper. Based on this, Figure 1 ,or Figure 4 or Figure 7 In the view shown, the upper side of the paper is the front direction, the lower side of the paper is the rear direction, the left side of the paper is the left direction, the right side of the paper is the right direction, the front side of the paper is the upper direction, and the back side of the paper is the lower direction.

[0071] like Figures 1 to 3 As shown, or as Figures 11 to 13 As shown, the zipper pull involved in the utility model includes a pull head body 40 and a zipper pull tab. The pull head body 40 includes an upper wing plate 41 and a lower wing plate 42 arranged opposite to each other in the upper and lower directions, a chain tooth passage formed between the upper wing plate 41 and the lower wing plate 42, and a pull tab mounting column 43 fixed on the upper surface of the upper wing plate 41, and some of the chain teeth on the chain belt are accommodated in the chain tooth passage. The zipper pull tab includes a pull tab body 10 and a pull tab auxiliary device 20. The front end of the pull tab body 10 is connected to the pull tab mounting column 43, thereby mounting the zipper pull tab as a whole on the upper surface of the pull head body 40; the rear end of the pull tab body 10 is detachably connected to the pull tab auxiliary device 20, so that the pull tab auxiliary device 20 can be replaced.

[0072] like Figure 4 and Figure 5 As shown, or as Figure 14 and Figure 15 As shown, the front section of the pull-tab body 10 is a slider mounting portion 13, which is used to connect to the slider mounting column 43 on the slider body 40. Preferably, the pull-tab body 10 is provided with a through column connection hole 14 in the slider mounting portion 13. The column connection hole 14 passes through the pull-tab body 10 along the thickness direction of the pull-tab body 10. The slider mounting portion 13 of the pull-tab body 10 is sleeved on the slider mounting column 43 of the slider body 40 through the column connection hole 14. Figures 1 to 3 As shown, or as Figures 11 to 13 As shown, the pull-tab body 10 is thereby mounted on the slider body 40 .

[0073] In particular, the zipper puller involved in this application is a zipper puller with a puller auxiliary device 20 that can be disassembled and assembled in a rotating manner. Figure 4 and Figure 5 As shown, or as Figure 14 and Figure 15 As shown, the rear section of the pull-tab body 10 is the appliance mounting portion 12, which is used to connect to the pull-tab auxiliary device 20. The pull-tab body 10 is provided with a through mounting hole 11 in the appliance mounting portion 12, and the appliance mounting portion 12 is distributed around the mounting hole 11. The mounting hole 11 is non-circular, such as oval, rectangular, waist-shaped, trapezoidal, etc., and the mounting hole 11 has different apertures in at least two intersecting directions. Figures 7 to 10 As shown, or as Figures 17 to 20 As shown, the pull-tab auxiliary device 20 includes a tool body 21 extending forward and backward, a tool column 22 extending downward from the front end of the tool body 21, and a tool head 23 fixed to the lower end of the tool column 22. The tool head 23 is fixed to the outer end of the tool column 22. The tool column 22 has a cylindrical or square structure, and the tool head 23 is non-circular, such as an elliptical, rectangular, waist-shaped, trapezoidal, etc., and has different lengths in at least two intersecting directions. The tool head 23 is elastically deformable; when the length direction of the tool head 23 aligns with the length direction of the mounting hole 11, the mounting hole 11 of the pull-tab main body 10 allows the elastically deformable tool head 23 in the pull-tab auxiliary device 20 to pass through. The mounting hole 11 of the pull-tab main body 10 also accommodates the tool column 22 of the pull-tab auxiliary device 20 and allows the tool column 22 to rotate.

[0074] Based on the above structure of the pull-tab main body 10 and the pull-tab auxiliary device 20, the pull-tab main body 10 and the pull-tab auxiliary device 20 can be separated and combined. Specifically, when the pull-tab auxiliary device 20 is installed, Figure 21As shown, first, the length direction of the tool head 23 is consistent with the length direction of the mounting hole 11, and the tool head 23 is aligned with the mounting hole 11, and then force is applied to press the tool head 23. Since the tool head 23 is elastically deformable and the length direction of the tool head 23 is consistent with the length direction of the mounting hole 11, that is, at this time the maximum length direction of the tool head 23 is consistent with the maximum aperture direction of the mounting hole 11, then force is applied to press the tool head 23 to easily press the tool head 23 into the mounting hole 11, so that the tool head 23 can easily pass through the mounting hole 11; then, the tool head 23 that has passed through the mounting hole 11 is removed. The pull-tab auxiliary device 20 rotates an angle so that the length direction of the tool head 23 intersects with the length direction of the mounting hole 11. Since the mounting hole 11 and the tool head 23 are both non-circular, after the rotation, at least the two ends of the tool head 23 in the maximum length direction will abut against the tool mounting portion 12. That is, after the rotation, the length direction dimension of the tool head 23 is greater than the hole pitch of the mounting hole 11 in this direction, which makes the part of the tool head 23 protruding from the tool column 22 abut against the tool mounting portion 12, limiting the tool head 23 from being separated from the mounting hole 11, and reliably connecting the pull-tab auxiliary device 20 to the pull-tab body 10. On the contrary, when disassembling the pull-tab auxiliary device 20, if Figure 22 As shown, the pull-tab assistant 20 is rotated until the length direction of the tool head 23 is consistent with the length direction of the mounting hole 11, and then force is applied to pull the tool head 23 out of the mounting hole 11. Since the maximum length direction of the tool head 23 is consistent with the maximum aperture direction of the mounting hole 11 at this time, and the tool head 23 can be elastically deformed, the tool head 23 can be easily pulled out of the mounting hole 11 when force is applied to pull out the pull-tab assistant 20, and the pull-tab assistant 20 can be detached from the pull-tab body 10.

[0075] Therefore, in the zipper pull tab involved in this application, the pull tab body 10 and the pull tab auxiliary device 20 are detachably connected, and different pull tab auxiliary devices 20 can be replaced. In particular, in this application, the operation of pressing the device head 23 into the mounting hole 11 is very easy, and then the installation of the pull tab auxiliary device 20 can be completed by simply rotating the pull tab auxiliary device 20, making the replacement of the pull tab auxiliary device 20 very easy. In this way, this application not only facilitates the installation and replacement of the pull tab auxiliary device 20, but also prevents the device body 21 from passing through the mounting hole 11, and thus does not cause any constraints on the device body 21 by the mounting hole 11, effectively preventing the mounting hole 11 from restricting the external design of the pull tab auxiliary device 20, so that this application can use pull tab auxiliary devices 20 of any shape, greatly improving and enriching the external design of the zipper pull tab, and ultimately improving and enriching the design sense of the zipper. In addition, the device column 22 and the device head 23 are both arranged on the lower side of the device body 21, that is, the back side, so that the front structure of the zipper pull is simple and clean, which is conducive to improving the aesthetics of the zipper pull.

[0076] Furthermore, the length direction of the mounting hole 11 may coincide with the length direction of the pull-tab body 10, may coincide with the width direction of the pull-tab body 10, or may intersect with both the length and width directions of the pull-tab body 10. Based on the different configurations of the mounting hole 11 and the device mounting portion 12 on the pull-tab body 10, and the different configurations of the device head 23 on the pull-tab auxiliary member 20, the zipper pull tab has multiple embodiments. Two preferred embodiments of the zipper pull tab are provided below.

[0077] Zipper puller embodiment 1

[0078] In the first embodiment of the zipper pull tab, the arrangement structure of the mounting hole 11 on the pull tab body 10 is preferably as follows: Figure 4 and Figure 5 As shown, the mounting hole 11 is a rectangular hole. The length direction of the mounting hole 11 is consistent with the width direction of the pull-tab body 10, and both are oriented horizontally. That is, the mounting hole 11 extends left and right along the width direction of the pull-tab body 10; and the mounting hole 11 penetrates the pull-tab body 10 along the thickness direction of the pull-tab body 10. The four corners of the mounting hole 11 with a rectangular hole structure are all circular arc segments 113. The mounting hole 11 with a rectangular hole structure has a rectangular hole wall profile. More specifically, the hole wall of the mounting hole 11 with a rectangular hole structure comprises a pair of horizontal straight hole walls 111 arranged side by side in a front-to-back manner, and a pair of vertical straight hole walls 112 arranged side by side in a left-to-right manner. The horizontal straight hole walls 111 extend straight left and right along the length direction of the mounting hole 11, and the vertical straight hole walls 112 extend straight front and back along the width direction of the mounting hole 11. Adjacent horizontal straight hole walls 111 and vertical straight hole walls 112 are transitionally connected by circular arc segments 113. Therefore, the diameter of the mounting hole 11 is largest between a pair of longitudinal straight hole walls 112 (ie, in the left-right direction), and the diameter of the mounting hole 11 is smallest between a pair of transverse straight hole walls 111 (ie, in the front-back direction).

[0079] Preferably, when the length direction of the device head 23 is consistent with the length direction of the mounting hole 11 and the device head 23 has passed through the mounting hole 11, there is a gap between the outer peripheral surface of the device column 22 and the pair of transverse straight hole walls 111 of the mounting hole 11, and there is also a gap between the outer peripheral surface of the device column 22 and the pair of longitudinal straight hole walls 112 of the mounting hole 11, thereby facilitating the subsequent easier rotation of the pull-tab auxiliary device 20, and also facilitating the installation operation of the pull-tab auxiliary device 20.

[0080] Further, if Figures 1 to 3 ,as well as Figures 8 to 10As shown, the tool head 23 extends straight forward and backward along the length direction of the tool body 21. The length direction of the tool head 23, the length direction of the tool body 21, and the length direction of the pull-tab body 10 are consistent, all in the front-to-back direction. The length direction dimension of the tool head 23 is greater than the hole pitch of the mounting hole 11 in the length direction of the pull-tab body 10. In this way, when installing the pull-tab auxiliary device 20, as shown in FIG. Figure 21 As shown, the pull-tab assistor 20 is first placed in a horizontal position, which aligns the length of the tool head 23 with the length of the mounting hole 11. Then, after the tool head 23 is pressed downward through the mounting hole 11, the pull-tab assistor 20 is rotated backward 90°. This effectively places the tool head 23 in contact with the surface of the tool mounting portion 12, thereby improving the connection reliability between the pull-tab assistor 20 and the pull-tab body 10. Furthermore, in this position, the tool body 21 of the pull-tab assistor 20 extends backward along the length of the pull-tab body 10, resulting in a highly consistent overall appearance of the zipper pull, which is beneficial for improving the integrity of the zipper pull and, consequently, the aesthetics of the zipper pull.

[0081] Further, if Figure 9 and Figure 10 As shown, the front and rear sides of the instrument head 23 have a first protrusion 231 extending outward from the instrument column 22 along its length direction (that is, along the length direction of the instrument body 21), and the left and right sides of the instrument head 23 have a second protrusion 232 extending outward from the instrument column 22 along its width direction (that is, along the width direction of the instrument body 21), or in other words, the first protrusion 231 is provided at the end of the instrument head 23 in its length direction, and the second protrusion 232 is provided at the end of the instrument head 23 in its width direction. In the front-to-back direction, the protruding lengths of the two first protrusions 231 relative to the instrument column 22 are W11 and W12 respectively; in the left-right direction, the protruding length of the second protrusion 232 relative to the instrument column 22 is W2; the protruding lengths W11 and W12 of the first protrusions 231 are both greater than the protruding length W2 of the second protrusion 232; in this way, when the length direction of the instrument head 23 is consistent with the length direction of the mounting hole 11, the size of the instrument head 23 in the width direction of the mounting hole 11 in this state can be reduced, so that the instrument head 23 can be more easily passed through the mounting hole when the instrument head 23 is pressed. In addition, the protruding lengths W11 and W12 of the first protrusion 231 and the protruding length W2 of the second protrusion 232 should satisfy the following requirements: when the tool head 23 is pressed downward, the tool head 23 can easily pass through the mounting hole 11; and, after the tool head 23 passes downward through the mounting hole 11 and the pull-tab assisting device 20 is rotated backward 90°, the length direction of the tool head 23 is perpendicular to the length direction of the mounting hole 11. At this time, a larger part of the first protrusion 231 abuts against the tool mounting portion 12, thereby reliably preventing the tool head 23 from detaching from the mounting hole 11.

[0082] Preferably, since the tool head 23 is disposed close to the front end of the tool body 21, the first protrusion 231 at the front end of the tool head 23 is closer to the outer edge of the tool body 21 than the first protrusion 231 at the rear end of the tool head 23. Thus, the first protrusion 231 at the front end of the tool head 23 is defined as the outer protrusion 233, and the first protrusion 231 at the rear end of the tool head 23 is defined as the inner protrusion 234. The outer protrusion 233 extends forward by a length W11, and the inner protrusion 234 extends backward by a length W12. In the first embodiment of the zipper pull tab, as shown in FIG. Figure 9 and Figure 10 As shown, the device head 23 has an asymmetric structure, the protruding length W11 of the front outer convex portion 233 of the device head 23 is smaller than the protruding length W12 of the rear inner convex portion 234, but the protruding lengths of the second convex portions 232 on the left and right sides of the device head 23 are equal.

[0083] Furthermore, if Figure 5 and Figure 6 As shown, the pull-tab body 10 has a first fixing groove 15 and a second fixing groove 16 on the back side of the fixture mounting portion 12. The first fixing groove 15 and the second fixing groove 16 are distributed along the length of the pull-tab body 10, on the front and rear sides of the mounting hole 11. In other words, the first fixing groove 15 and the second fixing groove 16 are respectively distributed on the outer circumferences of the two horizontal straight hole walls 111. When the fixture head 23 is pressed downward from the upper side of the pull-tab body 10 through the mounting hole 11 and rotated backward 90°, the length direction of the fixture head 23 and the length direction of the fixture body 21 are both aligned with the length direction of the pull-tab body 10, and the length direction of the fixture head 23 is perpendicular to the length direction of the mounting hole 11. The two first protrusions 231 at the front and rear ends of the fixture head 23 respectively engage in the first fixing groove 15 and the second fixing groove 16. Specifically, the outer protrusion 233 at the front engages in the first fixing groove 15 at the front side of the mounting hole 11, and the inner protrusion 234 at the rear engages in the second fixing groove 16 at the rear side of the mounting hole 11. Through the snap-fitting between the first fixing groove 15 and the outer protrusion 233, and the snap-fitting between the second fixing groove 16 and the inner protrusion 234, the reliability and stability of the pull-tab auxiliary device 20 installed in the pull-tab main body 10 are effectively improved, and the pull-tab auxiliary device 20 is reliably prevented from accidentally detaching from the pull-tab main body 10 and the pull-tab auxiliary device 20 is reliably prevented from rotating arbitrarily in the pull-tab main body 10.

[0084] Furthermore, if Figure 5 and Figure 6 As shown, the pull-tab body 10 is fixed with at least one first fixing buckle 30 on the back of the appliance mounting portion 12. The first fixing buckle 30 protrudes downward from the appliance mounting portion 12 along the thickness direction of the pull-tab body 10. The first fixing buckle 30 is distributed on the outer periphery of the first fixing groove 15 and / or the second fixing groove 16. In this embodiment, as shown in FIG. Figure 5 and Figure 6 As shown, there are two first fixing buckles 30, symmetrically distributed in the left-right direction around the outer periphery of the first fixing slot 15. When the two first protrusions 231 at the front and rear ends of the tool head 23 are respectively engaged in the first fixing slot 15 and the second fixing slot 16, the pair of first fixing buckles 30 respectively abut the left and right sides of the outer periphery of the tool head 23, further restricting the arbitrary rotation of the tool head 23 and more reliably improving the reliability and stability of the pull-tab auxiliary device 20 installed in the pull-tab body 10.

[0085] Furthermore, if Figure 5 and Figure 6 As shown, the groove wall profile of the first fixing groove 15 and the outer peripheral profile of the outer protrusion 233 are adapted to each other and are both semicircular; when disassembling the pull-tab auxiliary device 20, the semicircular first fixing groove 15 and the outer protrusion 233 facilitate the outer protrusion 233 to be rotated out of the first fixing groove 15, which also facilitates the disassembly operation of the pull-tab auxiliary device 20. In the front-to-back direction, the length of the inner protrusion 234 is greater than the length of the second fixing groove 16. The front end of the second fixing groove 16 extends forward to the rear edge of the mounting hole 11, and the rear end of the second fixing groove 16 passes through the rear edge of the device mounting portion 12 backward. The second fixing groove 16 is a front-to-back through-structure, which facilitates the processing of the second fixing groove 16 on the back of the device mounting portion 12. In particular, after the pull-tab auxiliary device 20 is installed, the inner protrusion 234 is clamped in the second fixing groove 16. Since the length of the inner protrusion 234 is greater than the length of the second fixing groove 16, a portion of the inner protrusion 234 is bound to extend backward from the pull-tab body 10, as shown in FIG. Figure 3 As shown, the area of ​​the contact portion between the inner protrusion 234 and the second fixing groove 16 is increased, thereby improving the reliability and stability of the pull-tab auxiliary device 20 installed in the pull-tab body 10.

[0086] Preferably, if Figure 8 As shown, the width of the tool head 23 in the left-right direction gradually increases from the outer protrusion 233 to the inner protrusion 234, and the left and right edges of the tool head 23 are inclined edges that are further away from the central axis of the tool head 23 as they move backward. The groove walls of the second fixing groove 16 abut the left and right sides of the inner protrusion 234, and the groove walls of the second fixing groove 16 are a pair of second inclined groove walls 17 that are symmetrically arranged on the left and right sides. The second inclined groove walls 17 extend in an inclined manner that they move further away from the central axis of the pull-tab body 10 as they move backward. Therefore, after the pull-tab auxiliary device 20 is installed, as shown in FIG. Figure 3As shown, the left edge of the tool head 23 is in the same inclination direction as the second inclined groove wall 17 on the left side of the second fixed groove 16, and the two are in abutment with each other. The right edge of the tool head 23 is in the same inclination direction as the second inclined groove wall 17 on the right side of the second fixed groove 16, and the two are in abutment with each other, which effectively limits the left and right shaking of the inner protrusion 234, and also limits the left and right shaking of the pull-tab auxiliary device 20.

[0087] Zipper puller embodiment 2

[0088] The difference between the second embodiment of the zipper puller and the first embodiment of the zipper puller lies in the shape of the mounting hole 11 , the back side structure of the device mounting portion 12 , and the shape of the device head 23 .

[0089] Specifically, in the second embodiment of the zipper puller, Figure 14 and Figure 15 As shown, the mounting hole 11 is a waist-shaped hole. The mounting hole 11 of the waist-shaped hole structure has a hole wall profile similar to an ellipse. More specifically, the hole wall of the mounting hole 11 of the waist-shaped hole structure has a pair of transverse straight hole walls 111 side by side in front and back, and a pair of arc hole walls 114 side by side in left and right. The transverse straight hole walls 111 extend straight left and right along the length direction of the mounting hole 11, and the pair of arc hole walls 114 are distributed at the left and right ends of the length direction of the mounting hole 11 and are connected between the pair of straight hole walls 111. Therefore, the aperture of the mounting hole 11 between the pair of arc hole walls 114 (i.e., in the left-right direction) is the largest, and the aperture of the mounting hole 11 between the pair of transverse straight hole walls 111 (i.e., in the front-back direction) is the smallest. As shown Figure 18 As shown, the outer contour of the tool head 23 is similar to an ellipse. When the length direction of the tool head 23 is consistent with the length direction of the mounting hole 11, the hole wall contour of the mounting hole 11 is adapted to the outer contour of the tool head 23, so that when the tool head 23 is pressed downward, the tool head 23 can easily pass through the mounting hole 11. Moreover, after the pull-tab auxiliary device 20 is rotated backward by 90 degrees, the tool head 23 can be better abutted against the surface of the tool mounting portion 12, improving the connection reliability between the pull-tab auxiliary device 20 and the pull-tab body 10.

[0090] Preferably, in the second embodiment of the zipper puller, Figure 19 and Figure 20 As shown, the device head 23 has a symmetrical structure, the first protrusions 231 on the front and rear sides of the device head 23 have the same protrusion length, and the second protrusions 232 on the left and right sides of the device head 23 have the same protrusion length.

[0091] Furthermore, if Figure 15 and Figure 16As shown, the pull-tab body 10 is secured to the back of the fixture mounting portion 12 with a pair of second fixing buckles 50 projecting downward along the thickness of the pull-tab body 10. These second fixing buckles 50 are symmetrically positioned on the front and rear sides of the mounting hole 11. Each second fixing buckle 50 has a third fixing slot 51 defined in the middle of the left-right direction. These third fixing slots 51 are formed on the lower surface of the fixture mounting portion 12, with two third fixing slots 51 symmetrically positioned on the back of the fixture mounting portion 12. Thus, the pair of second fixing buckles 50 and the mounting hole 11 form a cross-shaped snap-fit ​​structure on the back of the pull-tab body 10. The two third fixing slots 51 are located on the outer peripheries of the two horizontal, straight hole walls 111. After the tool head 23 is pressed downward from the upper side of the pull tab body 10 through the mounting hole 11 and rotated backward 90°, the length of the tool head 23 is aligned with that of the pull tab body 10 and perpendicular to the length of the mounting hole 11. The first protrusions 231 at each end of the tool head 23 snap into place within a pair of third fixing grooves 51. The snap-fitting engagement between the first protrusions 231 and the third fixing grooves 51 effectively enhances the reliability and stability of the pull tab auxiliary device 20 within the pull tab body 10. Therefore, the second zipper pull tab embodiment secures the tool head 23 via a pair of second fixing buckles 50, reliably preventing the pull tab auxiliary device 20 from accidentally detaching from the pull tab body 10.

[0092] Preferably, if Figure 15 As shown, the third fixing groove 51 has a pair of first inclined groove walls 52 symmetrically arranged along the width direction of the pull-tab body 10. The first inclined groove walls 52 extend in an inclined manner such that the further away from the mounting hole 11, the closer to the central axis of the pull-tab body 10. Figure 18 As shown, the outer periphery of the first protrusion 231 has a pair of inclined surfaces 24. When the first protrusion 231 is engaged in the third fixing groove 51, or in other words, when the length direction of the pull-tab auxiliary 20 is consistent with the length direction of the pull-tab body 10, as shown in FIG. Figure 12 As shown, the inclined direction of the inclined surface 24 is consistent with the inclined direction of the first inclined groove wall 52, and the two abut and cooperate, limiting the first protrusion 231 from swinging in the width direction of the pull-tab body 10. At the same time, when the pull-tab auxiliary device 20 is detached from the pull-tab body 10, the inclined first inclined groove wall 52 facilitates the first protrusion 231 to rotate out of the third fixing groove 51, thereby facilitating the removal of the pull-tab auxiliary device 20.

[0093] Preferably, when installing the pull-tab assisting device 20, when the device head 23 is pressed downward through the mounting hole 11 but the pull-tab assisting device 20 is not rotated, a pair of second fixing buckles 50 abut against the outer peripheral side of the inclined surface 24 of the outer periphery of the device head 23, limiting the arbitrary rotation of the pull-tab assisting device 20 at this time, so that the pull-tab assisting device 20 can only rotate when the user applies force.

[0094] Furthermore, in both embodiments of the zipper pull tab described above, an installation guide slope (not shown) is provided on the outer peripheral surface of the outer end of the tool head 23. The installation guide slope extends in an inclined manner such that the further away from the tool post 22, the closer to the central axis of the tool head 23. Thus, when installing the pull tab assisting device 20, the inclined installation guide slope facilitates the pressing of the tool head 23 through the mounting hole 11, further facilitating the installation operation of the pull tab assisting device 20.

[0095] Furthermore, in the two embodiments of the above zipper pull tabs, Figure 8 and Figure 9 As shown, or as Figure 18 and Figure 19 As shown, the rear end of the back of the device body 21 is provided with a slightly downwardly protruding friction-increasing ridge 25, which is used to increase the friction between the device body 21 and the user's fingers when the zipper slider is pulled back and forth by the rear end of the handheld device body 21, thereby playing an anti-slip role. Figure 9 or Figure 19 As shown, there is an inclined extension section 211 in the middle of the device body 21, and the inclined extension section 211 extends in an inclined manner as it goes backward and upward. The front section of the device body 21 in front of the inclined extension section 211 and the rear section of the device body 21 behind the inclined extension section 211 both extend straight back and forth, thereby making the rear section of the device body 21 away from the surface of the zipper, making it easier for users to better hold the device body 21.

[0096] Furthermore, the pull-tab body 10 having the above-mentioned structure is a metal part with an integrated structure. In this embodiment, the pull-tab body 10 is a zinc alloy part, so the pull-tab body 10 has good structural strength and is durable. The pull-tab auxiliary device 20 having the above-mentioned structure is a plastic part with an integrated structure, such as a hard plastic part, a soft plastic part, a rubber part, or a resin part. It is easy to manufacture and has low cost. It is easy to design a variety of pull-tab auxiliary devices 20 with different shapes and colors at low cost. Combined with the detachable structure of the pull-tab auxiliary device 20 on the pull-tab body 10, it is convenient for users to replace different pull-tab auxiliary devices 20, enriching the design sense of the zipper. In addition, during the process of disassembling and assembling the pull-tab auxiliary device 20, even if the pull-tab auxiliary device 20 is damaged, or even if the pull-tab auxiliary device 20 is damaged after using it for a period of time, it will not have a big impact due to the low cost of the pull-tab auxiliary device 20.

[0097] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0098] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
