Description

Technical Field

[0001] This utility model relates to the field of zipper technology, and in particular to a self-locking double-sided zipper pull. Background Technology

[0002] Existing double-sided zipper pulls typically use a U-shaped guide rail structure, resulting in a relatively large overall thickness and affecting the user experience. To solve this problem, some technicians have tried using ropes instead of guide rails. However, the ends of the ropes require the attachment of three-dimensional decorative elements, posing safety hazards. Furthermore, zipper pulls pulled by ropes often lack a self-locking function and are unsuitable for applications such as children's clothing. Existing self-locking zipper pulls usually consist of a zipper body, a pull tab, an elastic element, a cap, and a hook. The elastic element is fixed between the cap and the zipper body. During use, pulling the pull tab lifts the hook, opening and closing the zipper. However, this structure suffers from low assembly efficiency, cumbersome processes, and a high rate of product scrap, and the elastic element material is also expensive.

[0003] Therefore, how to provide a thin, self-locking double-sided zipper pull is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a double-sided zipper pull with a smaller thickness and self-locking capability, which can solve the problem of large total thickness of double-sided self-locking zipper pulls, as well as the problem that zipper pulls that use ropes on both sides often lack self-locking function.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A self-locking double-sided zipper pull, comprising:

[0007] The slider body includes an upper wing plate, a lower wing plate, and a connecting post connecting the two. The connecting post has a through-hole along its axial direction, and the lower wing plate has a second through-hole at the end opposite to the connecting post.

[0009] The elastic element is snapped between the cover plate and the upper wing plate. The elastic element includes a locking part and a connecting part. The locking part is used to pass through the lock hole provided in the upper wing plate to lock the slider body. The connecting part can pass through the fourth through hole when pulled to drive the locking part to unlock the slider body.

[0010] The pull rope passes through the second through hole, the first through hole, the third through hole and the fourth through hole in sequence. One end of the pull rope is fixed to the second through hole and the other end is fixed to the connecting part.

[0011] In one possible implementation, a positioning groove is provided on the side of the upper wing plate away from the lower wing plate, and the elastic member includes a positioning part for engaging with the positioning groove to fix the elastic member.

[0012] In one possible implementation, the upper wing plate has an inwardly recessed mounting groove on the side opposite to the lower wing plate. The elastic element includes a mounting part and a locking part connected to the mounting part. The mounting groove is used to mount the mounting part, and the mounting part can move within the space formed by the cover plate and the mounting groove to drive the locking part to lock or unlock.

[0013] In one possible implementation, the elastic element includes an elastic bend that is angularly connected to the mounting portion, and the cover plate is provided with an elastic bend groove for engaging with the elastic bend.

[0014] In one possible implementation, a snap-fit ​​groove is provided in the middle of the mounting part, and two sets of positioning parts and elastic bends are provided symmetrically about the snap-fit ​​groove. A snap-fit ​​protrusion that mates with the snap-fit ​​groove is provided on the upper wing plate.

[0015] In one possible implementation, the connecting part is located in the middle of the mounting part, and the connecting part is provided with a pull hole for fixing one end of the pull rope.

[0016] In one possible implementation, two connecting protrusions are provided on the side of the upper wing plate away from the lower wing plate, and the two connecting protrusions are distributed at both ends of the upper wing plate along the moving direction of the pull head body, and the cover plate is provided with connecting grooves that cooperate with the connecting protrusions at corresponding positions.

[0017] In one possible implementation, the lower wing plate is located on the side near the upper wing plate and has a rope end slot on the outer periphery of the second through hole.

[0018] In one possible implementation, knots are provided at both ends of the pull rope, one of which is engaged with the rope end slot and the other is engaged with the pull hole.

[0019] This utility model also provides a self-locking double-sided zipper pull, comprising:

[0020] The slider body includes an upper wing plate, a lower wing plate, and a connecting post connecting the two. The connecting post has a through-hole along its axial direction.

[0021] Cover plate, installed on the zipper pull body;

[0022] The elastic element is snapped onto the cover plate and the upper wing plate. The elastic element includes a locking part, which is used to pass through the lock hole provided in the upper wing plate to lock the pull head body. The elastic element is also provided with a pull hole.

[0023] A pull rope, passing through at least the first through hole and the pull hole, is used to pull the pull head;

[0024] Pulling the rope unlocks the pull head body by pulling the drive locking part.

[0025] Compared to the aforementioned background technology, the present invention provides a self-locking double-sided zipper pull, comprising: a zipper pull body, a cover plate, an elastic element, and a pull cord; the zipper pull body includes an upper wing plate, a lower wing plate, and a connecting post connecting the two, the connecting post having a through-hole along its axial direction, and the lower wing plate having a second through-hole at the end opposite to the connecting post; the cover plate is installed on the zipper pull body, having a third through-hole corresponding to the first through-hole, and a fourth through-hole at the end of the cover plate opposite to the third through-hole; the elastic element is engaged between the cover plate and the upper wing plate, the elastic element including a locking part and a connecting part, the locking part being used to pass through the locking hole provided in the upper wing plate to lock the zipper pull body, and the connecting part being able to pass through the fourth through-hole when pulled to drive the locking part to unlock the zipper pull body; the pull cord sequentially passes through the second through-hole, the first through-hole, the third through-hole, and the fourth through-hole, one end of the pull cord being fixed to the second through-hole, and the other end being fixed to the connecting part.

[0026] Specifically, the pull cord passes sequentially through the second, first, third, and fourth through holes, with its two ends fixed to the connecting part and the second through hole, respectively. When the pull cord is pulled from the first side, one end of the cord causes the connecting part to rise, and simultaneously the locking part rises, unlocking the zipper head and allowing the zipper to be pulled smoothly. After the pull cord is released, the locking part returns to its original position under the action of elasticity. Similarly, when the second cord is used to pull, the force is transmitted to the connecting part through the cord, achieving the same effect of the locking part retracting from the zipper, allowing for easy opening and closing of the zipper. After the pull cord is released, the locking part returns to its original position under the action of elasticity. This design allows the pull cord to replace the U-shaped guide rail structure in traditional double-sided zipper heads, thereby reducing the thickness of the zipper head. Moreover, the elastic element also enables the zipper head to self-lock. Attached Figure Description

[0042] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation.

[0043] The purpose of this invention is to provide a double-sided zipper pull with a smaller thickness and self-locking capability, which can solve the problem of large total thickness of double-sided self-locking zipper pulls, as well as the problem that zipper pulls that use ropes on both sides often lack self-locking function.

[0044] To achieve the above objectives, the present invention provides the following technical solution:

[0045] Please see Figures 1 to 7 This embodiment provides a self-locking double-sided zipper pull, including: a zipper pull body 100, a cover plate 200, an elastic element 300, and a pull cord 400; the zipper pull body 100 includes an upper wing plate 110, a lower wing plate 120, and a connecting post 130 connecting the two, the connecting post 130 is provided with a through-hole 131 along its axial direction, and the lower wing plate 120 is provided with a second through-hole 121 at one end away from the connecting post 130; the cover plate 200 is installed on the zipper pull body 100, and is provided with a third through-hole 210 corresponding to the first through-hole 131, and the end of the cover plate 200 away from the third through-hole 210 is provided with a... The fourth through hole 220; the elastic element 300 is engaged between the cover plate 200 and the upper wing plate 110. The elastic element 300 includes a locking part 310 and a connecting part 320. The locking part 310 is used to pass through the lock hole 111 provided in the upper wing plate 110 to lock the slider body 100. The connecting part 320 can pass through the fourth through hole 220 when pulled to drive the locking part 310 to unlock the slider body 100. The pull rope 400 passes through the second through hole 121, the first through hole 131, the third through hole 210 and the fourth through hole 220 in sequence. One end of the pull rope 400 is fixed to the second through hole 121 and the other end is fixed to the connecting part 320.

[0046] Specifically, the zipper head body 100 in this embodiment includes three parts: an upper wing plate 110, a lower wing plate 120, and a connecting post 130. The three parts are an integral structure. The zipper head body 100 can be integrally molded by injection molding. Using plastic material can reduce the overall weight of the double-sided zipper head.

[0047] A through-hole 131 is provided on the axis of the connecting post 130. A third through-hole 210 is provided at the tail end of the lower wing plate 120. Since the cover plate 200 is installed on the upper wing plate 110, a third through-hole 210 is provided at the position corresponding to the first through-hole 131. In addition, a fourth through-hole 220 is provided at the tail end of the upper wing plate 110. The fourth through-hole 220 facilitates the extension of the connecting part 320 of the elastic element 300 from the center outward. Therefore, the cross-sectional shape and size of the fourth through-hole 220 can be set according to the actual shape and size of the connecting part 320. In this embodiment, the material of the elastic element 300 can be, but is not limited to, stainless steel or copper. It is installed between the upper wing plate 110 and the cover plate 200. When the connecting part 320 is not under tension, the locking part 310 passes through the locking hole 111 on the upper wing plate 110 and locks onto the zipper, thereby locking the zipper pull to restrict its movement. Specifically, as shown in the figure... Figure 6 As shown; when the connecting part 320 is pulled outward through the fourth through hole 220, it will also cause the locking part 310 to move upward, separating it from the zipper, thereby unlocking the zipper pull, as shown in the details. Figure 7 As shown; in this embodiment, the movement of the connecting part 320 is achieved by the pull rope 400 connected to it. That is, when the pull rope 400 receives a pulling force, it pulls the connecting part 320 outward to extend the fourth through hole 220. When the pulling force is removed, the locking part 310 of the elastic element 300 will automatically return to its original position and the locking part 310 will pass through the lock hole 111 again, thereby locking the pull head.

[0048] The pull cord 400 passes sequentially through the second through hole 121, the first through hole 131, the third through hole 210, and the fourth through hole 220, with its two ends fixed to the connecting part 320 and the second through hole 121, respectively. When the pull cord 400 is pulled from the first side, one end of the pull cord 400 will cause the connecting part 320 to rise, and at the same time, the locking part 310 will rise synchronously, unlocking the pull head body 100 smoothly. Specifically, as shown... Figure 7 As shown, after the pull rope 400 is released, the locking part 310 resets and locks under the action of elasticity, as detailed below. Figure 6 As shown. Similarly, when the second rope is pulled, the force is transmitted to the connecting part 320 through the pull rope 400, which also achieves the effect of the locking part 310 retracting the zipper, allowing the zipper to be opened and closed at will. When the pull rope 400 is released, the locking part 310 returns to its original position and locks under the action of elasticity. With this design, the pull rope 400 can replace the U-shaped guide rail structure in the traditional double-sided zipper, thereby reducing the thickness of the zipper. Moreover, the elastic element 300 can also achieve the self-locking of the zipper.

[0049] In one possible implementation, the upper wing plate 110 is provided with a positioning groove 112 on the side opposite to the lower wing plate 120, and the elastic member 300 includes a positioning part 330, which is used to engage with the positioning groove 112 to fix the elastic member 300.

[0050] Specifically, such as Figure 2 and Figure 4 As shown, a recessed, strip-shaped positioning groove 112 is provided on the outer side of the upper wing plate 110 near the head. Correspondingly, the positioning part 330 of the elastic member 300 is a downwardly bent edge. In this way, when installing the elastic member 300, the positioning part 330 only needs to be inserted into the positioning groove 112 to fix the elastic member 300, which can prevent the elastic member 300 from moving at will.

[0051] Furthermore, the upper wing plate 110 has an inwardly recessed mounting groove 113 on the side opposite to the lower wing plate 120. The elastic member 300 includes a mounting part 340 and a locking part 310 connected to the mounting part 340. The mounting groove 113 is used to mount the mounting part 340, and the mounting part 340 can move within the space formed by the cover plate 200 and the mounting groove 113 to drive the locking part 310 to lock or unlock.

[0052] Understandably, when the connecting part 320 moves upward, that is, when it lifts towards the cover plate 200, it needs a certain amount of room to move. Therefore, in this embodiment, an inwardly recessed mounting groove 113 is provided on the outer side of the upper wing plate 110 near the positioning groove 112. Correspondingly, the elastic member 300 is provided with a mounting part 340 that matches the shape of the mounting groove 113. When the connecting part 320 is not lifted by tension, the mounting part 340 will be tightly attached to the mounting groove 113 under the elastic action of the elastic member 300. When the connecting part 320 is lifted by tension, it will drive the mounting part 340 to lift upward, thereby allowing the locking part 310 to also lift upward to unlock the pull head.

[0053] Furthermore, the elastic element 300 includes an elastic bend 350 that is angularly connected to the mounting portion 340, and the cover plate 200 is provided with an elastic bend groove 230 for cooperating with the elastic bend 350.

[0054] Specifically, such as Figure 3 and Figure 4In this embodiment, the elastic bend 350 and the mounting portion 340 are angled together. This means that after the cover plate 200 is installed, both the elastic bend 350 and the mounting portion 340 are compressed. The mounting portion 340 is pressed downwards into the mounting groove 113, while the elastic bend 350 is pressed precisely into the elastic bend slot 230. Thus, only when the connecting portion 320 is pulled up will the mounting portion 340 and the locking portion 310 overcome the pressure exerted by the elastic bend 350 and lift up. When the force on the connecting portion 320 is removed, the mounting portion 340 will re-adhere to the mounting portion 340. Furthermore, the elastic bend slot 230 also serves to limit the movement of the elastic bend 350, preventing the elastic element 300 from moving in the lateral direction.

[0055] Furthermore, the mounting part 340 is provided with a snap-fit ​​groove 341 in the middle, and the positioning part 330 and the elastic bending part 350 are both provided with two sets of snap-fit ​​grooves 341 symmetrically. The upper wing plate 110 is provided with snap-fit ​​protrusions 114 that cooperate with the snap-fit ​​grooves 341.

[0056] Specifically, such as Figure 2 and Figure 4 As shown, when the elastic element 300 is installed, the snap-fit ​​groove 341 will engage with the snap-fit ​​protrusion 114 provided on the upper wing plate 110, which can further restrict the movement of the elastic element 300. In this embodiment, the positioning part 330 and the elastic bend 350 are symmetrically arranged about the snap-fit ​​groove 341, so that the elastic element 300 has a longer service life and prevents the pull head from losing its self-locking function after one side of the elastic bend 350 loses its elasticity.

[0057] In this embodiment, the various protrusions and slots that can cooperate with each other make the elastic element 300 easy and convenient to install onto the corresponding position on the upper wing plate 110. This arrangement can reduce the assembly difficulty of the double-sided zipper and improve its assembly efficiency.

[0058] In this embodiment, the connecting part 320 is disposed in the middle of the mounting part 340, and the connecting part 320 is provided with a pull hole 321, which is used to fix one end of the pull rope 400.

[0059] Specifically, such as Figure 4 As shown, the connecting part 320 is located on the straight line of the axis of symmetry of the mounting part 340. It has an L-shaped bent structure. A pull hole 321 is provided on the plane that extends into the fourth through hole 220. The pull hole 321 is provided to facilitate the connection between the pull rope 400 and the connecting part 320. The specific connection method can be adjusted according to the actual situation. This article does not make specific limitations here.

[0060] In one possible implementation, the upper wing plate 110 is provided with two connecting protrusions 115 on the side opposite to the lower wing plate 120, and the two connecting protrusions 115 are distributed at both ends of the upper wing plate 110 along the moving direction of the pull head body 100. The cover plate 200 is provided with corresponding connecting grooves 240 that cooperate with the connecting protrusions 115.

[0061] Specifically, such as Figure 2 and Figure 3 As shown, in this embodiment, the connection between the cover plate 200 and the slider body 100 is achieved through connecting protrusions 115 and connecting grooves 240. Specifically, connecting protrusions 115 are provided at the middle of both ends of the upper wing plate 110, and correspondingly, two connecting grooves 240 are provided on the cover plate 200 at the opposite position. Additionally, two rivet slots 116 are provided on the opposite side of the two connecting protrusions 115. Thus, once the cover plate 200 is installed in place, rivets can be driven into the corresponding rivet slots 116 on its outer side to complete the fixed connection of the cover plate 200 and the slider body 100. Of course, this is only one connection method; other connection methods can also be selected for the cover plate 200 and the slider body 100. This is not specifically limited here.

[0062] In one possible implementation, the elastic element 300 is integrally formed by bending.

[0063] In this embodiment, in order to reduce the processing difficulty of the elastic element 300 and increase the production efficiency of the elastic element 300, it is set as an integral structure; the elastic element 300 is first cut into the corresponding shape during production and then bent to complete the processing and manufacturing.

[0064] In one possible implementation, the lower wing plate 120 is located on the side near the upper wing plate 110, and a rope end slot 122 is provided on the outer periphery of the second through hole 121.

[0065] Understandably, in order to allow the other end of the pull rope 400 to be hidden inside the pull head body 100, and to facilitate the fixed connection of the end, this embodiment also provides a rope end slot 122 on the inner side of the lower wing plate 120.

[0066] Furthermore, the two ends of the pull rope 400 are respectively provided with knots 410, one of the two knots 410 is locked to the rope end slot 122, and the other is locked to the pull hole 321.

[0067] In this embodiment, by providing large knots 410 at both ends of the pull rope 400, the two ends of the pull rope 400 are prevented from detaching from the second through hole 121 or from the connecting part 320.

[0068] In summary, this application provides a self-locking double-sided zipper pull, comprising four parts: a zipper pull body, a cover plate 200, an elastic element 300, and a pull cord 400. The elastic element 300 is sandwiched between the zipper pull body and the cover plate 200. The positioning part 330 of the elastic element 300 is engaged in the positioning groove 112 of the zipper pull body, and the locking part 310 passes through the lock hole 111 to perform the locking function. The two elastic bends 350 of the elastic element 300 are respectively engaged in the elastic bend slots 230. During the pulling process, the elastic element plays an elastic role to ensure that the locking part 310 is pulled up and returned to its original position. The pulling hole 321 provided in the middle of the connecting part 320 of the elastic element 300 can pass through the fourth through hole 220 on the cover plate 200. After the elastic element 300 is positioned between the pull head body and the cover plate 200, the cover plate 200 is fixed by riveting four points, that is, the cover plate 200 is riveted so that it generates rivet points inward and is engaged in the rivet groove 116 on the connecting protrusion 115.

[0069] After the zipper head is assembled, the pull cord 400 passes sequentially through the pull hole 321 on the elastic element 300, the third through hole 210 on the cover plate 200, the first through hole 131 and the second through hole 121 on the zipper head body 100. The two ends of the pull cord 400 are knotted. The first knot 410 is fixed in the pull hole 321 of the elastic element 300 and hidden in the fourth through hole 220. The second knot 410 is fixed and hidden in the cord end slot 122. When the pull cord 400 is pulled from the first side, the first knot 410 causes the connecting part 320 of the elastic element 300 to rise, and the locking part 310 rises simultaneously. After unlocking, the zipper head can be pulled smoothly. After the pull cord 400 is released, the locking part 310 returns to its original position and locks under the action of elasticity. Similarly, when the second pull cord 400 is used to pull, the force is transmitted through the pull cord 400 body to the connecting part 320 of the elastic element 300, and the locking part 310 retracts the zipper, achieving the effect of opening and closing the zipper at will. When the pull cord 400 is released, the locking part 310 returns to its original position and locks under the action of elasticity. The principle diagram of the locking and unlocking states is as follows. Figure 6 and Figure 7 As shown.

[0070] This utility model also provides a self-locking double-sided zipper pull, including: a zipper pull body 100, a cover plate 200, an elastic element 300, and a pull cord 400; the zipper pull body 100 includes an upper wing plate 110, a lower wing plate 120, and a connecting post 130 connecting the two, the connecting post 130 having a through hole 131 along its axial direction; the cover plate 200 is installed on the zipper pull body 100; the elastic element 300 is engaged with the cover plate 200 and the upper wing plate 110, the elastic element 300 including a locking part 310, the locking part 310 being used to pass through the locking hole 111 provided in the upper wing plate 110 to lock the zipper pull body 100, the elastic element 300 also having a pull hole 321; the pull cord 400 passes through at least the first through hole 131 and the pull hole 321, and is used to pull the zipper pull; the pull cord unlocks the zipper pull body 100 by pulling the locking part 310.
