Description

[Technical field]

[0001] The present invention relates to the technical field of fasteners, and in particular to a zipper puller with a rotatable and detachable puller assistant, and a zipper slider including the zipper puller. [Background technology]

[0002] Nowadays, zippers are widely used in everyday items such as clothing, bags, tents, and bedding, and zippers are used to assemble and separate items.

[0003] Usually, a fastener mainly includes a pair of cloth tapes, a chain fixed to the inner edge of each cloth tape, and a slider, the slider includes a slider body attached to the chain and a pull tab attached to the surface of the slider body, and the pair of chains are engaged or disengaged by holding the pull tab and pulling the slider body along the length direction of the fastener, thereby opening and closing the fastener accordingly. In order to improve the design of the fastener, in the prior art, some fasteners are provided with a pull tab assistant that is detachably attached to the pull tab of the fastener slider, and the pull tab assistant not only improves the convenience of pulling the slider, but also enriches the design of the fastener.

[0004] For example, in the split combination puller disclosed in the Chinese utility model with the license number CN217446885U, the rear puller and the front puller are detachably connected by engaging the connecting post of the rear puller with the connecting hole of the front puller. However, since the outer diameter of the end of the connecting post of the rear puller is much larger than the diameter of the connecting hole, a large force is required to press the connecting post into the connecting hole, making it difficult to install the connecting post by pressing it into the connecting hole.

[0005] For example, in the fastener puller disclosed in the Chinese patent with the license number CN110811084B, when attaching the puller auxiliary device, the puller auxiliary part of the puller auxiliary device is passed through the mounting hole of the puller main body, and then the head position is restricted so that the neck part of the end of the puller auxiliary part is held in the mounting hole of the puller main body. This makes it easy to attach the puller auxiliary device, but since the puller auxiliary part needs to pass through the mounting hole during attachment and the other end of the puller auxiliary part away from the neck part is the grip part, the shape of the grip part is restricted by the mounting hole of the puller main body, making it difficult to design the outer shape of the grip part more freely, and the outer shape of the puller auxiliary device is restricted. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above-mentioned shortcomings of the prior art, the technical problem that the present invention aims to solve is to provide a zipper puller with a rotatable and detachable puller assistant, which makes it easy to install the puller assistant and does not restrict the external design of the puller assistant. [Means for solving the problem]

[0007] In order to achieve the above object, the present invention provides a zipper puller with a rotatable and detachable puller auxiliary, the zipper puller including a puller body and a puller auxiliary, the puller body having a through mounting hole and an auxiliary attachment part distributed around the outer periphery of the mounting hole, the puller auxiliary including an auxiliary body, an auxiliary post part extending from the auxiliary body, and an auxiliary head part fixedly installed on the outer end of the auxiliary post part, The auxiliary head is an elastically deformable body, the mounting hole has a different hole diameter in at least two intersecting directions, the auxiliary head has a different length in at least two intersecting directions, and the auxiliary post portion can be rotatably accommodated in the mounting hole, When the length direction of the auxiliary head coincides with the length direction of the mounting hole, the mounting hole allows the elastically deformable auxiliary head to pass through; When the pull handle auxiliary rotates until the length direction of the auxiliary head intersects with the length direction of the mounting hole, the auxiliary head abuts against the auxiliary mounting portion.

[0008] In this application, the mounting hole and the auxiliary head are both installed in a non-circular structure, so that the mounting hole has different hole diameters in at least two intersecting directions, and the auxiliary head has different lengths in at least two intersecting directions, so that the mounting hole has a large hole diameter in its length direction, and the auxiliary head has a large length in its length direction. In this way, when the length direction of the auxiliary head and the length direction of the mounting hole are consistent, the elastic deformation characteristics of the auxiliary head allow the auxiliary head to be easily and conveniently pressed into the mounting hole, so that the auxiliary head easily passes through the mounting hole, and then the puller auxiliary is rotated by a certain angle so that the length direction of the auxiliary head and the length direction of the mounting hole intersect, and at this time, the auxiliary head and the auxiliary mounting part abut against each other, restricting the auxiliary head from coming off the mounting hole, and the puller auxiliary is reliably connected to the puller body. Therefore, in this application, the operation of pressing the head of the auxiliary into the mounting hole is very simple, not only making it easy to install and replace the puller auxiliary, but also the mounting hole does not impose any restrictions on the main body of the auxiliary, that is, there is no restriction on the external design of the puller auxiliary, so that in this application, puller auxiliary of any external shape can be used, greatly improving and enriching the design of the zipper puller, and finally improving and enriching the design of the zipper.

[0009] Furthermore, the installation structure of the mounting hole in the pull tab body is preferably as follows: the mounting hole is a waist-shaped hole or a rectangular hole, the mounting hole extends linearly along the width direction of the pull tab body, i.e., the length direction of the mounting hole and the width direction of the pull tab body coincide with each other, and the mounting hole penetrates the pull tab body along the thickness direction of the pull tab body.

[0010] Preferably, the mounting hole has a waist-shaped hole or a rectangular hole structure, so that the hole wall of the mounting hole has a pair of horizontal straight hole walls extending along the width direction of the puller body, the length direction of the auxiliary head and the length direction of the mounting hole are aligned, and when the auxiliary head passes through the mounting hole, there is a gap between the outer circumferential surface of the auxiliary post and the pair of horizontal straight hole walls of the mounting hole, which makes it easier to rotate the subsequent puller auxiliary and to install the puller auxiliary.

[0011] Furthermore, the length direction of the auxiliary head, the length direction of the auxiliary body, and the length direction of the puller body are all consistent. When the auxiliary head is pressed through the mounting hole and then rotated until its length direction coincides with the length direction of the puller body, the auxiliary head is brought into good contact with the surface of the auxiliary mounting part, improving the connection reliability between the puller auxiliary and the puller body. In this state, the auxiliary body of the puller auxiliary extends along the length direction of the puller body, so that the overall outer shape of the zipper puller has a very good consistency, which helps to improve the overall appearance of the zipper puller and the appearance of the zipper puller.

[0012] Furthermore, the auxiliary head has a first protrusion extending outward from the auxiliary post along the length of the auxiliary body and a second protrusion extending outward from the auxiliary post along the width of the auxiliary body, the extension length of the first protrusion being greater than the extension length of the second protrusion, and when the length of the auxiliary head intersects with the length of the mounting hole, the first protrusion abuts against the auxiliary mounting part, thereby reliably preventing the auxiliary head from coming off the mounting hole.

[0013] Furthermore, a first fixing groove and a second fixing groove are formed on the surface of the auxiliary attachment part of the puller body, and the first fixing groove and the second fixing groove are distributed on both sides of the attachment hole along the length direction of the puller body, and when the puller auxiliary head passes through the attachment hole and rotates until the length direction of the auxiliary head coincides with the length direction of the puller body, the length direction of the auxiliary head and the length direction of the attachment hole intersect, and the two first protrusions at both ends of the length direction of the auxiliary head are respectively engaged with the first fixing groove and the second fixing groove. In this way, after the attachment of the puller auxiliary is completed, the engagement structure in which the two first protrusions are respectively engaged with the first fixing groove and the second fixing groove reliably restricts the auxiliary head from rotating or coming off freely, and also reliably restricts the puller auxiliary from rotating or coming off freely, thereby improving the attachment reliability of the puller auxiliary.

[0014] Preferably, at least one first fixing buckle is fixedly installed on the surface of the auxiliary attachment part of the puller body, the first fixing buckle protrudes from the auxiliary attachment part along the thickness direction of the puller body, the first fixing buckle is distributed on the outer periphery of the first fixing groove and / or the second fixing groove, and when the length direction of the auxiliary head coincides with the length direction of the puller body, the first fixing buckle abuts against the outer periphery of the auxiliary head, thereby further improving the attachment reliability of the puller auxiliary.

[0015] Preferably, the two first convex parts at both ends of the auxiliary head are an outer convex part and an inner convex part, the groove wall contour of the first fixing groove and the outer peripheral contour of the outer convex part are matched and both are semicircular, the length of the inner convex part is greater than the length of the second fixing groove, the second fixing groove penetrates the outer edge of the auxiliary attachment part along the length direction of the puller body, when the length direction of the auxiliary head and the length direction of the puller body are consistent, the outer convex part is engaged with the first fixing groove, the inner convex part is engaged with the second fixing groove, and a part of the inner convex part extends outside the puller body. When the puller auxiliary is removed, the semicircular first fixing groove and the outer convex part make it easy to rotate the outer convex part and remove it from the first fixing groove, and the removal operation of the puller auxiliary is also easy, and at the same time, the second fixing groove with a double-end through structure is easy to process.

[0016] Furthermore, a second fixing buckle protruding along the thickness direction of the puller body is fixedly installed on the surface of the auxiliary attachment part of the puller body, and a pair of third fixing grooves are formed on the second fixing buckle, and the pair of third fixing grooves are formed on the surface of the auxiliary attachment part and distributed on both sides of the attachment hole along the length direction of the puller body, and when the puller auxiliary head passes through the attachment hole and rotates until the length direction of the auxiliary head and the length direction of the puller body coincide with each other, the length direction of the auxiliary head and the length direction of the attachment hole intersect, and the two first protrusions at both ends of the length direction of the auxiliary head are respectively engaged with a pair of the third fixing grooves. In this way, the engagement between the first protrusions and the third fixing grooves effectively improves the attachment reliability and stability of the puller auxiliary to the puller body, and reliably prevents the puller auxiliary from being accidentally removed from the puller body.

[0017] Preferably, the third fixing groove has at least one first inclined groove wall, the first inclined groove wall extends at an incline so as to approach the central axis of the pull handle body as it moves away from the mounting hole, and the outer periphery of the first protrusion has at least one inclined surface. When the first protrusion is engaged with the third fixing groove, the inclined surface and the first inclined groove wall have the same inclination direction and abut and engage with each other, thereby limiting the wobbling of the first protrusion in the width direction of the pull handle body. In addition, when the pull handle auxiliary is removed from the pull handle body, the first inclined groove wall installed at an incline makes it easy to rotate the first protrusion and remove it from the third fixing groove, and also makes it easy to remove the pull handle auxiliary.

[0018] The outer peripheral surface of the outer end of the auxiliary head is provided with an installation guide inclined surface that extends at an incline so as to approach the central axis of the auxiliary head as it moves away from the auxiliary column. In this way, when installing the pull aid, the inclined installation guide inclined surface makes it easy to press the auxiliary head to pass through the installation hole, making the installation operation of the pull aid even easier.

[0019] Furthermore, since the puller body is an integral metal member, it has high structural strength and excellent durability; at the same time, the puller assistant is an integral plastic member, which is easy to manufacture and low cost, and it is easy to design puller assistants with multiple different shapes and different colors at low cost. Combined with the removable structure of the puller assistant on the puller body, it is easy for users to replace different puller assistants, enriching the design of the fastener.

[0020] The present invention further provides a fastener slider, which includes a slider body and the above-mentioned fastener pull tab, and the pull tab body is connected to the slider body. Effect of the Invention

[0021] As described above, the zipper puller and zipper slider with a rotatable and detachable puller assistant according to the present invention have the following beneficial effects:

[0022] In this application, both the mounting hole and the head of the auxiliary device are installed in a non-circular structure, and the contours of both are compatible. In this way, when the length direction of the head of the auxiliary device and the length direction of the mounting hole are consistent, the head of the auxiliary device can be easily and conveniently pressed into the mounting hole, so that the head of the auxiliary device easily passes through the mounting hole, and then the puller auxiliary device is rotated by a certain angle, and the head of the auxiliary device and the auxiliary device mounting part abut against each other, thereby restricting the head of the auxiliary device from coming off the mounting hole, and the puller auxiliary device is securely connected to the puller body. Therefore, in this application, the operation of pressing the head of the auxiliary device into the mounting hole is very simple, and not only is it easy to install and replace the puller auxiliary device, but the mounting hole does not cause any restriction on the auxiliary device body, that is, it does not restrict the external design of the puller auxiliary device. As a result, in this application, any external shape of the puller auxiliary device can be used, which greatly improves and enriches the design of the zipper puller, and ultimately improves and enriches the design of the zipper.

If the combination of technical means is contradictory or cannot be realized, it should be considered that such combination of technical means does not exist and is not included in the scope of protection of this application.

[0028] This application relates to the technical field of fasteners. For convenience of explanation, in the following embodiments, the length direction of the fastener is defined as the front-rear direction, the width direction of the fastener is defined as the left-right direction, and the thickness direction of the fastener is defined as the up-down direction. The fastener includes a pair of cloth tapes distributed mainly side by side on the left and right, a chain fixed to the inner edge of each cloth tape and extending forward and backward, and a fastener slider, and the fastener slider is attached to the chain so as to be slidable forward and backward. When the fastener slider is moved forward, the pair of chains mesh with each other to close the fastener, and when the fastener slider is moved backward, the pair of chains separate to open the fastener.

[0029] This invention mainly relates to a zipper slider and a zipper pull tab used for the zipper slider. The length, width and thickness directions of the zipper slider correspond one-to-one to the length, width and thickness directions of the zipper, and the length, width and thickness directions of the zipper pull tab also correspond one-to-one to the length, width and thickness directions of the zipper. Based on this, in the drawings shown in Figure 1, Figure 4 or Figure 7, 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 up direction, and the back side of the paper is the down direction.

[0030] As shown in Figs. 1 to 3 or Figs. 11 to 13, the fastener slider according to the present invention includes a slider body 40 and a fastener puller. The slider body 40 includes an upper wing 41 and a lower wing 42 that are arranged vertically opposite to each other, an element passage formed between the upper wing 41 and the lower wing 42, and a puller attachment post 43 fixed to the upper surface of the upper wing 41, and a part of the element of the chain is accommodated in the element passage. The fastener puller includes a puller body 10 and a puller auxiliary 20, and the front end of the puller body 10 is connected to the puller attachment post 43, so that the entire fastener puller is attached to the upper surface of the slider body 40, and the rear end of the puller body 10 is removably connected to the puller auxiliary 20, so that the puller auxiliary 20 is replaceable.

[0031] As shown in Figures 4 and 5, or as shown in Figures 14 and 15, the front part of the pull tab main body 10 is the slider attachment part 13 which is connected to the pull tab attachment post part 43 of the slider body 40. Preferably, the slider attachment part 13 of the pull tab main body 10 is provided with a penetrating post part connection hole 14, and as shown in Figures 1 to 3 or as shown in Figures 11 to 13, the post part connection hole 14 penetrates the pull tab main body 10 along the thickness direction of the pull tab main body 10, and the slider attachment part 13 of the pull tab main body 10 is fitted into the pull tab attachment post part 43 of the slider body 40 through the post part connection hole 14, whereby the pull tab main body 10 is attached to the slider body 40.

[0032] In particular, the zipper puller according to the present application is a zipper puller with a rotatable and detachable puller auxiliary device 20. As shown in Figures 4 and 5, or as shown in Figures 14 and 15, the rear part of the puller body 10 is an auxiliary device attachment part 12 connected to the puller auxiliary device 20. The auxiliary device attachment part 12 of the puller body 10 is provided with penetrating attachment holes 11, which are distributed around the outer periphery of the attachment holes 11, and the attachment holes 11 are not perfect circles but are, for example, oval, rectangular, waist-shaped, or trapezoidal, and therefore the hole diameters of the attachment holes 11 are different in at least two intersecting directions. As shown in Figures 7 to 10 or 17 to 20, the puller auxiliary 20 includes an auxiliary body 21 extending forward and backward, an auxiliary column 22 extending downward from the front end of the auxiliary body 21, and an auxiliary head 23 fixedly installed at the lower end of the auxiliary column 22, that is, the auxiliary head 23 is fixedly installed at the outer end of the auxiliary column 22, the auxiliary column 22 has a cylindrical structure or a rectangular column structure, and the auxiliary head 23 is not a perfect circle, but is, for example, an ellipse, a rectangle, a waist shape, a trapezoid, etc., so that the auxiliary head 23 has different lengths in at least two intersecting directions. The auxiliary head 23 is an elastically deformable body, and when the length direction of the auxiliary head 23 and the length direction of the mounting hole 11 coincide with each other, the mounting hole 11 of the puller body 10 allows the elastically deformable auxiliary head 23 in the puller auxiliary 20 to pass through. The attachment hole 11 of the pull handle body 10 also accommodates the auxiliary device post 22 of the pull handle auxiliary device 20, and the auxiliary device post 22 is rotatable.

[0033] The pull handle main body 10 and the pull handle auxiliary 20 having the above-mentioned structure can realize the separation and connection of the pull handle main body 10 and the pull handle auxiliary 20. Specifically, when attaching the pull handle auxiliary 20, as shown in Fig. 21, first, the length direction of the auxiliary head 23 is aligned with the length direction of the mounting hole 11, the auxiliary head 23 is aligned with the mounting hole 11, and then the auxiliary head 23 is biased and pressed. Since the auxiliary head 23 is elastically deformable and the length direction of the auxiliary head 23 is aligned with the length direction of the mounting hole 11, at this time, the maximum length direction of the auxiliary head 23 is aligned with the maximum hole diameter direction of the mounting hole 11, and the auxiliary head 23 can be easily pressed into the mounting hole 11 by biasing and pressing the auxiliary head 23. As a result, the auxiliary head 23 easily passes through the mounting hole 11, and then the auxiliary head 23 is biased and pressed. The pull handle auxiliary 20, whose auxiliary head 23 has passed through the mounting hole 11, is rotated a certain angle so that the length direction of the auxiliary head 23 intersects with the length direction of the mounting hole 11, and since neither the mounting hole 11 nor the auxiliary head 23 are perfect circles, after rotation, at least both ends of the auxiliary head 23 in the maximum length direction abut against the auxiliary mounting portion 12, in other words, after rotation, the dimension of the auxiliary head 23 in the length direction is larger than the hole diameter of the mounting hole 11 in that direction, so that the part of the auxiliary head 23 protruding from the auxiliary column portion 22 abuts against the auxiliary mounting portion 12, restricting the auxiliary head 23 from coming off the mounting hole 11, and ensuring that the pull handle auxiliary 20 is securely connected to the pull handle main body 10. Conversely, when removing the pull handle auxiliary device 20, as shown in FIG. 22, the pull handle auxiliary device 20 is rotated until the length direction of the auxiliary device head 23 coincides with the length direction of the mounting hole 11, and then the auxiliary device head 23 is forced to be pulled out of the mounting hole 11; at this time, the maximum length direction of the auxiliary device head 23 coincides with the maximum hole diameter direction of the mounting hole 11 and the auxiliary device head 23 is elastically deformable, so that when the pull handle auxiliary device 20 is forced to be pulled out, the auxiliary device head 23 can be easily pulled out of the mounting hole 11 and the pull handle auxiliary device 20 can be removed from the pull handle main body 10.

[0034] Therefore, in the fastener puller according to the present application, the puller main body 10 and the puller auxiliary 20 are detachably connected, and different puller auxiliary 20 can be replaced. In particular, in the present application, the operation of pressing the auxiliary head 23 into the mounting hole 11 is very easy, and then the installation of the puller auxiliary 20 can be completed by simply rotating the puller auxiliary 20, making it very easy to replace the puller auxiliary 20. Therefore, in the present application, not only is the installation and replacement of the puller auxiliary 20 easy, but the mounting hole 11 does not cause any restriction on the auxiliary main body 21 because the auxiliary main body 21 is prevented from passing through the mounting hole 11, that is, the mounting hole 11 does not restrict the external design of the puller auxiliary 20. As a result, in the present application, puller auxiliary 20 of any external shape can be used, greatly improving and enriching the design of the fastener puller, and ultimately improving and enriching the design of the fastener. In addition, the auxiliary device column 22 and the auxiliary device head 23 are both installed on the underside of the auxiliary device body 21, i.e., on the back side, so that the front structure of the zipper puller is simple and neat, which helps improve the appearance of the zipper slider.

[0035] Furthermore, the length direction of the mounting hole 11 may coincide with the length direction of the puller body 10, may coincide with the width direction of the puller body 10, or may intersect with both the length direction and the width direction of the puller body 10. Based on different shapes of the mounting hole 11 and the auxiliary attachment portion 12 in the puller body 10 and different shapes of the auxiliary head portion 23 in the puller auxiliary 20, the fastener puller has multiple embodiments. Two preferred embodiments of the fastener puller are provided below.

[0036] [Zipper puller example 1] In the first embodiment of the fastener puller, the mounting hole 11 in the puller body 10 is preferably provided with the following structure. As shown in Figures 4 and 5, the mounting hole 11 is a rectangular hole, and the length direction of the mounting hole 11 and the width direction of the puller body 10 coincide with each other and are both left-right directions, that is, the mounting hole 11 extends left-right along the width direction of the puller body 10 and penetrates the puller body 10 along the thickness direction of the puller body 10. All four corners of the mounting hole 11 having the rectangular hole structure are arc-shaped segments 113. The mounting hole 11 with a rectangular hole structure has a rectangular hole wall contour, and more specifically, the hole walls of the mounting hole 11 with a rectangular hole structure have a pair of horizontal linear hole walls 111 arranged in the front and rear and a pair of vertical linear hole walls 112 arranged in the left and right, the horizontal linear hole walls 111 extending linearly from left to right along the length direction of the mounting hole 11, the vertical linear hole walls 112 extending linearly from front to back along the width direction of the mounting hole 11, and the adjacent horizontal linear hole walls 111 and vertical linear hole walls 112 are all connected by transitions via arc-shaped segments 113. Therefore, the hole diameter of the mounting hole 11 between the pair of vertical linear hole walls 112 (i.e., in the left-right direction) is the largest, and the hole diameter of the mounting hole 11 between the pair of horizontal linear hole walls 111 (i.e., in the front-back direction) is the smallest.

[0037] Preferably, the length direction of the auxiliary device head 23 coincides with the length direction of the mounting hole 11, and when the auxiliary device head 23 passes through the mounting hole 11, there is a gap between the outer peripheral surface of the auxiliary device column portion 22 and a pair of horizontal linear hole walls 111 of the mounting hole 11, and there is also a gap between the outer peripheral surface of the auxiliary device column portion 22 and a pair of vertical linear hole walls 112 of the mounting hole 11, which makes it easier to rotate the pull handle auxiliary device 20 subsequently and also makes the installation operation of the pull handle auxiliary device 20 easier.

[0038] 1 to 3 and 8 to 10, the auxiliary head 23 extends linearly from front to back along the length of the auxiliary body 21, and the length of the auxiliary head 23, the length of the auxiliary body 21, and the length of the pull handle body 10 are all aligned in the front-to-back direction. The dimension of the auxiliary head 23 in the length direction is larger than the hole diameter of the mounting hole 11 in the length direction of the pull handle body 10. In this way, when attaching the pull handle auxiliary 20, as shown in FIG. 21, the pull handle auxiliary 20 is first placed in a horizontal state, that is, the length of the auxiliary head 23 is aligned with the length of the mounting hole 11, and then the auxiliary head 23 is pressed downward to penetrate the mounting hole 11, and then the pull handle auxiliary 20 is rotated 90° backward, so that the auxiliary head 23 is satisfactorily abutted against the surface of the auxiliary attachment portion 12, and the connection reliability between the pull handle auxiliary 20 and the pull handle body 10 can be improved.

[0039] In this state, the auxiliary device body 21 of the puller auxiliary device 20 extends rearward along the length of the puller body 10, so that the overall external shape of the zipper puller has very good conformity, which helps to improve the overall appearance of the zipper puller and also improves the appearance of the zipper puller.

[0040] Furthermore, as shown in Figures 9 and 10, the auxiliary head 23 has a first protrusion 231 on both the front and rear sides that extends outside the auxiliary column 22 along its length (i.e., the length direction of the auxiliary main body 21), and the auxiliary head 23 has a second protrusion 232 on both the left and right sides that extends outside the auxiliary column 22 along its width (i.e., the width direction of the auxiliary main body 21).In other words, the first protrusion 231 is located at the end of the auxiliary head 23 in the length direction, and the second protrusion 232 is located at the end of the auxiliary head 23 in the width direction. In the front-to-back direction, the extension lengths of the two first protrusions 231 relative to the auxiliary column portion 22 are W11 and W12, respectively, and in the left-to-right direction, the extension length of the second protrusion 232 relative to the auxiliary column portion 22 is W2, and the extension lengths W11 and W12 of the first protrusion 231 are both greater than the extension length W2 of the second protrusion 232. In this way, when the length direction of the auxiliary head 23 and the length direction of the mounting hole 11 coincide with each other, the dimension of the auxiliary head 23 in the width direction of the mounting hole 11 in this state can be reduced, making it easier for the auxiliary head 23 to pass through the mounting hole 11 when pressed. Furthermore, the extension lengths W11 and W12 of the first protrusion 231 and the extension length W2 of the second protrusion 232 should satisfy the following: when the auxiliary device head 23 is pressed downward, the auxiliary device head 23 can easily pass through the mounting hole 11; and when the auxiliary device head 23 passes downward through the mounting hole 11 and the pull handle auxiliary device 20 is rotated backward by 90°, the length direction of the auxiliary device head 23 is perpendicular to the length direction of the mounting hole 11; at this time, most of the first protrusion 231 abuts against the auxiliary device mounting portion 12, thereby reliably preventing the auxiliary device head 23 from coming off the mounting hole 11.

[0041] Preferably, the auxiliary head 23 is installed close to the front end of the auxiliary body 21, so that the first convex portion 231 at the front end of the auxiliary head 23 is closer to the outer edge of the auxiliary body 21 than the first convex portion 231 at the rear end of the auxiliary head 23. In this manner, the first convex portion 231 at the front end of the auxiliary head 23 is defined as the outer convex portion 233, the first convex portion 231 at the rear end of the auxiliary head 23 is defined as the inner convex portion 234, the forward extension length of the outer convex portion 233 is W11, and the rearward extension length of the inner convex portion 234 is W12. In the zipper puller embodiment 1, as shown in Figures 9 and 10, the auxiliary head 23 has an asymmetric structure, and the extension length W11 of the outer convex portion 233 on the front side of the auxiliary head 23 is smaller than the extension length W12 of the inner convex portion 234 on the rear side, but the extension lengths of the second convex portions 232 on both the left and right sides of the auxiliary head 23 are equal.

[0042] Furthermore, as shown in Figures 5 and 6, a first fixing groove 15 and a second fixing groove 16 are formed on the back surface of the auxiliary device mounting portion 12 of the pull handle body 10, and the first fixing groove 15 and the second fixing groove 16 are distributed on both the front and rear sides of the mounting hole 11 along the longitudinal direction of the pull handle body 10. In other words, the first fixing groove 15 and the second fixing groove 16 are respectively distributed on the outer circumferential sides of the two horizontal linear hole walls 111. When the auxiliary device head 23 is pressed downward from the top of the pull handle body 10 to pass through the mounting hole 11 and rotated 90 degrees backward, the length direction of the auxiliary device head 23 and the length direction of the auxiliary device body 21 both coincide with the length direction of the pull handle body 10, the length direction of the auxiliary device head 23 is perpendicular to the length direction of the mounting hole 11, and the two first protrusions 231 at the front and rear ends of the auxiliary device head 23 are engaged with the first fixing groove 15 and the second fixing groove 16, respectively; that is, the outer protrusion 233 at the front end is engaged with the first fixing groove 15 on the front side of the mounting hole 11, and the inner protrusion 234 at the rear end is engaged with the second fixing groove 16 on the rear side of the mounting hole 11. The engagement between the first fixing groove 15 and the outer convex portion 233, and the engagement between the second fixing groove 16 and the inner convex portion 234, effectively improves the reliability and stability of the attachment of the pull handle assistant 20 to the pull handle body 10, and reliably prevents the pull handle assistant 20 from accidentally coming off the pull handle body 10 and from rotating on its own within the pull handle body 10.

[0043] 5 and 6, at least one first fixing buckle 30 is fixedly installed on the back surface of the auxiliary device attachment part 12 of the pull handle body 10, and the first fixing buckle 30 protrudes downward from the auxiliary device attachment part 12 along the thickness direction of the pull handle body 10, and the first fixing buckle 30 is distributed on the outer circumferential side of the first fixing groove 15 and / or the second fixing groove 16. In this embodiment, as shown in Figs. 5 and 6, there are two first fixing buckles 30, and the two first fixing buckles 30 are symmetrically distributed on the outer circumferential side of the first fixing groove 15 in the left-right direction. When the two first protrusions 231 at the front and rear ends of the auxiliary device head 23 are engaged with the first fixing groove 15 and the second fixing groove 16, respectively, the pair of first fixing buckles 30 abut against both the left and right sides of the outer circumference of the auxiliary device head 23, further restricting uncontrolled rotation of the auxiliary device head 23 and more reliably improving the reliability and stability of the attachment of the pull handle auxiliary device 20 to the pull handle main body 10.

[0044] 5 and 6, the groove wall contour of the first fixing groove 15 and the outer peripheral contour of the outer protrusion 233 match and are both semicircular. When removing the puller auxiliary device 20, the semicircular first fixing groove 15 and the outer protrusion 233 make it easy to rotate the outer protrusion 233 and remove it from the first fixing groove 15, and the removal operation of the puller auxiliary device 20 is also easy. In the front-rear direction, the length of the inner protrusion 234 is longer 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 penetrates the rear edge of the auxiliary device mounting part 12 backward, so that the second fixing groove 16 has a front-rear through structure, which makes it easy to process the second fixing groove 16 on the back surface of the auxiliary device mounting part 12. In particular, after the installation of the pull handle auxiliary device 20 is completed, the inner convex portion 234 is engaged with the second fixing groove 16, and since the length of the inner convex portion 234 is greater than the length of the second fixing groove 16, as shown in FIG. 3, a part of the inner convex portion 234 inevitably extends rearward from the pull handle body 10, thereby increasing the area of ​​the contact portion between the inner convex portion 234 and the second fixing groove 16, and improving the reliability and stability of the installation of the pull handle auxiliary device 20 to the pull handle body 10.

[0045] 8, the width of the auxiliary head 23 in the left-right direction gradually increases from the outer convex portion 233 toward the inner convex portion 234, so that the left and right edges of the auxiliary head 23 are both inclined edges that move away from the central axis of the auxiliary head 23 toward the rear. The groove walls of the second fixing groove 16 abut on both the left and right sides of the inner convex portion 234, so that the groove walls of the second fixing groove 16 become a pair of second inclined groove walls 17 that are installed symmetrically, and the second inclined groove walls 17 extend at an angle so as to move away from the central axis of the pull handle body 10 toward the rear. Therefore, after the installation of the pull handle auxiliary device 20 is completed, as shown in Figure 3, the left edge of the auxiliary device head 23 and the second inclined groove wall 17 on the left side of the second fixing groove 16 have the same inclination direction and abut and engage, and the right edge of the auxiliary device head 23 and the second inclined groove wall 17 on the right side of the second fixing groove 16 have the same inclination direction and abut and engage, thereby effectively restricting the left and right wobble of the pull handle auxiliary device 20.

[0046] [Zipper puller example 2] The difference between the fastener puller of the second embodiment and the fastener puller of the first embodiment is that the shape of the attachment hole 11, the structure on the back side of the auxiliary device attachment portion 12, and the shape of the auxiliary device head portion 23 are different.

[0047] Specifically, in the second embodiment of the fastener puller, as shown in Figs. 14 and 15, the mounting hole 11 is a waist-shaped hole. The waist-shaped mounting hole 11 has a substantially elliptical hole wall contour, and more specifically, the hole wall of the waist-shaped mounting hole 11 has a pair of horizontal linear hole walls 111 arranged in the front and rear and a pair of arc-shaped hole walls 114 arranged in the left and right, the horizontal linear hole walls 111 extend linearly to the left and right along the length of the mounting hole 11, and the pair of arc-shaped hole walls 114 are distributed at both the left and right ends of the length of the mounting hole 11 and are connected between the pair of horizontal linear hole walls 111. Therefore, the mounting hole 11 has the largest hole diameter between the pair of arc-shaped hole walls 114 (i.e., in the left and right direction) and the smallest hole diameter between the pair of horizontal linear hole walls 111 (i.e., in the front and rear direction). As shown in Fig. 18, the outer peripheral contour of the auxiliary head 23 is substantially elliptical. When the length direction of the auxiliary device head 23 and the length direction of the mounting hole 11 coincide, the hole wall contour of the mounting hole 11 fits the outer peripheral contour of the auxiliary device head 23, so that when the auxiliary device head 23 is pressed downward, the auxiliary device head 23 can easily pass through the mounting hole 11, and then, by rotating the pull handle auxiliary device 20 backward by 90 degrees, the auxiliary device head 23 can be brought into good contact with the surface of the auxiliary device mounting portion 12, thereby improving the connection reliability between the pull handle auxiliary device 20 and the pull handle main body 10.

[0048] Preferably, in the zipper puller embodiment 2, as shown in Figures 19 and 20, the auxiliary head 23 has a symmetrical structure, the extension lengths of the first protrusions 231 on both the front and rear sides of the auxiliary head 23 are equal, and the extension lengths of the second protrusions 232 on both the left and right sides of the auxiliary head 23 are equal.

[0049] 15 and 16, a pair of second fixing buckles 50 protruding downward along the thickness direction of the puller body 10 are fixedly installed on the back surface of the auxiliary device mounting part 12 of the puller body 10, and the pair of second fixing buckles 50 are distributed symmetrically on both the front and rear sides of the mounting hole 11. A third fixing groove 51 is formed at the middle position in the left-right direction of each second fixing buckle 50, and the third fixing groove 51 is formed on the lower surface of the auxiliary device mounting part 12, and there are two third fixing grooves 51 on the back surface of the auxiliary device mounting part 12, which are symmetrical in the front-rear direction. In this way, the pair of second fixing buckles 50 and the mounting hole 11 form a cross buckle structure formed on the back surface of the puller body 10, and the two third fixing grooves 51 are distributed on the outer circumferential sides of the two horizontal linear hole walls 111, respectively. When the auxiliary head 23 is pressed downward from the upper side of the puller body 10 to pass through the mounting hole 11 and rotated backward by 90°, the length direction of the auxiliary head 23 coincides with the length direction of the puller body 10 and is perpendicular to the length direction of the mounting hole 11, and the first convex parts 231 at both ends of the length direction of the auxiliary head 23 are respectively engaged with the pair of third fixing grooves 51. The engagement between the first convex parts 231 and the third fixing grooves 51 effectively improves the reliability and stability of the puller auxiliary 20 attached to the puller body 10. Therefore, in the second embodiment of the fastener puller, the auxiliary head 23 is fixed by the pair of second fixing buckles 50, and the puller auxiliary 20 is reliably prevented from being inadvertently detached from the puller body 10.

[0050] Preferably, as shown in Fig. 15, the third fixing groove 51 has a pair of first inclined groove walls 52 symmetrically arranged along the width direction of the pull handle body 10, and the first inclined groove walls 52 extend at an incline so as to approach the central axis of the pull handle body 10 as they move away from the mounting hole 11. As shown in Fig. 18, the first protrusion 231 has a pair of inclined surfaces 24 on the outer periphery. When the first protrusion 231 is engaged with the third fixing groove 51, in other words, when the length direction of the pull handle assistant 20 and the length direction of the pull handle body 10 coincide with each other, as shown in Fig. 12, the inclined surfaces 24 and the first inclined groove walls 52 coincide with each other and come into contact with each other to engage with each other, thereby restricting the rattling of the first protrusion 231 in the width direction of the pull handle body 10. In addition, when removing the pull handle auxiliary device 20 from the pull handle main body 10, the first inclined groove wall 52, which is installed at an angle, makes it easy to rotate the first convex portion 231 and remove it from the third fixed groove 51, making it easy to remove the pull handle auxiliary device 20.

[0051] Preferably, when attaching the pull aid 20, the head 23 is pressed downward to pass through the attachment hole 11, and when the pull aid 20 is not rotated, the pair of second fixing buckles 50 abut against the outer circumferential side of the inclined surface 24 on the periphery of the head 23, at which time the free rotation of the pull aid 20 is restricted and the pull aid 20 can rotate only when the user applies force.

[0052] Furthermore, in the two embodiments of the fastener puller described above, an installation guide inclined surface is provided on the outer peripheral surface of the outer end of the auxiliary head 23, and the installation guide inclined surface is provided with an installation guide inclined surface (not shown) that extends at an incline so as to approach the central axis of the auxiliary head 23 the further it is from the auxiliary column portion 22. In this way, when attaching the puller auxiliary 20, the inclined installation guide inclined surface makes it easy to press the auxiliary head 23 to pass it through the attachment hole 11, making the installation operation of the puller auxiliary 20 even easier.

[0053] Furthermore, in the above two embodiments of the zipper puller, as shown in Figures 8 and 9, or as shown in Figures 18 and 19, the rear end of the rear of the auxiliary device body 21 is provided with a friction-increasing ridge 25 that protrudes slightly downward, and when the user holds the rear end of the auxiliary device body 21 in his / her hand and pulls the zipper slider back and forth, the friction-increasing ridge 25 can increase the friction between the auxiliary device body 21 and the user's fingers, and play the role of anti-slip. Also, as shown in Figures 9 and 19, the auxiliary device body 21 has an inclined extension 211 in the middle, which extends in an upward inclination toward the rear, and the front part of the inclined extension 211 of the auxiliary device body 21 and the rear part of the inclined extension 211 of the auxiliary device body 21 both extend linearly forward and backward, so that the rear part of the auxiliary device body 21 is separated from the surface of the zipper, making it easier for the user to hold the auxiliary device body 21.

[0054] Furthermore, the puller body 10 having the above structure is an integral metal member, and in this embodiment, the puller body 10 is a zinc alloy member, so that the structural strength is high and the durability is excellent. The puller auxiliary 20 having the above structure is an integral plastic member, for example, it may be a hard plastic member, a soft plastic member, a rubber member or a resin member, and is easy to manufacture, low cost, and easy to design a plurality of different shapes and different colors of the puller auxiliary 20 at low cost. Combined with the removable structure of the puller auxiliary 20 in the puller body 10, it is easy for users to replace different puller auxiliary 20, enriching the design of the fastener. In addition, even if the puller auxiliary 20 is damaged in the process of attaching and detaching the puller auxiliary 20 or is damaged after a certain period of use, it will not have a significant impact because the cost of the puller auxiliary 20 is low.

[0055] As described above, the present invention effectively overcomes various shortcomings in the prior art and has high industrial applicability.

[0056] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention.
