Abstract
Description
Technical Field
[0001] This utility model relates to the field of zipper technology, and in particular to a rotary lock zipper head. Background Technology
[0002] Zippers are an essential functional component in clothing and bags. They consist of two fabric strips on both sides and a slider in the middle. The slider is generally called the zipper head, which has the function of engaging the zipper teeth on both sides. In addition, the zipper head has a protruding hook-shaped component inside, which contacts the zipper teeth to prevent the zipper head from sliding freely on the zipper and plays the role of locking the zipper head.
[0003] The hook-shaped component inside a standard zipper pull is a hook-shaped latch. It typically works in conjunction with the zipper pull cap, internal elastic element, and zipper pull tab to lock the zipper. When the zipper pull tab is pulled up, it lifts the elastic element and the latch, allowing the zipper to normally engage the zipper teeth on both sides. When the zipper pull tab is released naturally without external force, the elastic element and the latch fall, locking the latch between the zipper teeth. In this state, the zipper cannot slide freely on the zipper teeth. Because the zipper pull tab is subjected to external force, and the entire zipper, including the zipper pull, is used on soft clothing, the external force on the zipper pull tab is not constant. This results in inconsistent contact between the latch and the zipper teeth when the tab is pulled up. Since the latch component is small and sharp, it can easily scratch the surface of the zipper teeth or even damage the electroplating layer, affecting the zipper's appearance.
[0004] Therefore, how to provide a rotary lock zipper head to eliminate friction between the hook and the zipper teeth, thereby reducing the risk of the hook scratching the zipper teeth, is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0014] Preferably, the slot is located on the bottom surface of the snap-fit cavity, and the slot is located on the side of the snap-fit cavity axis facing the third direction.
[0015] Preferably, the hook lock hole is located on the end face of the cylindrical buckle, and the line connecting the hook lock hole and the cylindrical buckle is perpendicular to the axis of the through hole.
[0016] Preferably, the hook lock also includes a mounting sleeve, which is installed inside the hook lock socket and moves along a first direction. The locking part is connected to the end of the mounting sleeve away from the connecting post. The mounting sleeve is provided with a receiving channel for installing an elastic element. The elastic element is located in the receiving channel, with one end abutting against the connecting post and the other end abutting against the locking part.
[0017] Preferably, the slot has a tapering opening away from the first direction.
[0018] Preferably, the locking part is a tapered structure that gradually narrows away from the first direction.

[0020] Preferably, the cylindrical buckle and the buckle cavity are interference fit to prevent the connecting column from shaking when no external force is applied.
[0021] Preferably, the locking part is an arc-shaped structure that gradually narrows away from the first direction.
[0022] Compared to the aforementioned background technology, the present invention provides a rotary lock zipper head, comprising: a zipper head body, a connecting post, a hook lock, an elastic element, and a pull tab; the zipper head body includes an upper wing plate, a lower wing plate, and a lock cylinder connecting the two; the connecting post is rotatably connected to the upper wing plate, and its rotation axis is parallel to a first direction; the hook lock is installed in a hook lock insertion hole provided near the end of the lower wing plate of the connecting post, the hook lock includes a locking part, the upper wing plate is provided with a slot for the locking part to pass through, and an elastic element for driving the locking part to extend out of the slot is installed in the hook lock insertion hole; the pull tab is connected to the connecting post through a crossbar, and the pull tab can drive the connecting post to rotate around its axis; when the crossbar is parallel to the second direction, the locking part can extend out of the slot to lock the zipper, and when the crossbar is parallel to the third direction, the locking part retracts into the slot to unlock the zipper.
[0023] Specifically, the zipper pull body is mounted on the zipper and has racks for opening and closing the zipper. The upper and lower wing plates are located on the upper and lower sides of the zipper, respectively, while the lock cylinder connects the upper and lower wing plates and is located between the two racks. A connecting post connects the pull tab to the zipper pull body. The bottom end of the connecting post is rotatably mounted on the upper wing plate, and the top end of the connecting post is connected to the crossbar of the pull tab. A hook lock that can move in a first direction is also installed at the bottom end of the connecting post. The lower end of the hook lock has a locking part, and an elastic element is installed between the upper end of the hook lock and the connecting post. This elastic element allows the locking part to pass through a plug provided at the bottom of the upper wing plate. The trend of the slot: When the pull tab is located on the zipper engagement plane, that is, when the locking part of the hook lock is exactly aligned with the slot, it will extend out of the slot under the action of the elastic element to lock the zipper. When the pull tab rotates to the left or right, it will drive the connecting post to rotate, which will in turn drive the hook lock to rotate, thereby causing the locking part to deviate from the slot, thus making the zipper head in the unlocked state. With this setting, the rotation of the hook lock can be controlled by rotating the pull tab of the zipper head. When the zipper rotates, the hook lock will not contact the zipper teeth, eliminating the friction between the hook lock and the zipper teeth, thereby reducing the risk of the hook lock scratching the zipper teeth.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0047] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0048] 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. Therefore, they should not be construed as limitations of this utility model.
[0049] The purpose of this invention is to provide a rotary lock zipper head to eliminate friction between the hook and the zipper teeth, thereby reducing the risk of the hook scratching the zipper teeth.
[0050] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, the Y direction as the second direction, and the Z direction as the third direction. The first direction, the second direction, and the third direction are perpendicular to each other.
[0051] To achieve the above objectives, the present invention provides the following technical solution:
[0052] Please see Figures 1 to 15This embodiment provides a rotary lock zipper pull, including: a zipper pull body 100, a connecting post 200, a hook lock 300, an elastic element 400, and a pull tab 500; the zipper pull body 100 includes an upper wing plate 110, a lower wing plate 120, and a lock cylinder 121 connecting the two; the connecting post 200 is rotatably connected to the upper wing plate 110, and its rotation axis is parallel to a first direction; the hook lock 300 is installed in a hook lock insertion hole 210 provided near the end of the connecting post 200 near the lower wing plate 120, and the hook lock 300 includes a locking part 31. 0. The upper wing plate 110 is provided with a slot 111 through which the locking part 310 passes. The hook lock insertion hole 210 is equipped with an elastic element 400 for driving the locking part 310 to extend out of the slot 111. The pull tab 500 is connected to the connecting post 200 through the crossbar 510. The pull tab 500 can drive the connecting post 200 to rotate around its axis. When the crossbar 510 is parallel to the second direction, the locking part 310 extends out of the slot 111 to lock the zipper. When the crossbar 510 is parallel to the third direction, the locking part 310 retracts into the slot 111 to unlock the zipper.
[0053] Specifically, the zipper head body 100 is installed on the zipper and is used to open and close the zipper rack. The upper wing plate 110 and the lower wing plate 120 are located on the upper and lower sides of the zipper, respectively. The lock cylinder 121 connects the upper wing plate 110 and the lower wing plate 120 and is located between the two racks. The lock cylinder 121 also has the function of separating the teeth when the zipper is opened.
[0054] The connecting post 200 is used to connect the pull tab 500 to the pull head body 100. Specifically, the bottom end of the connecting post 200 is rotatably mounted at the middle position of the upper wing plate 110. In this embodiment, the connecting post 200 is a columnar structure. In the installed state, its axis is parallel to the first direction, and it can rotate around its own axis on the upper wing plate 110. The top end of the connecting post 200 is connected to the crossbar 510 of the pull tab 500. The crossbar 510 is cylindrical and is a detachable component. A hook lock insertion hole 210 is provided at the bottom end of the connecting post 200 off-center from the axis. A hook lock insertion hole 210 is installed in the hook lock insertion hole 210, which can move along the first direction. The hook lock 300 has a locking part 310 at its lowest end. An elastic element 400 is installed between the upper end of the hook lock 300 and the connecting post 200. At the same time, the upper wing plate 110 is located below the connecting post 200 and has a slot 111 for the locking part 310 to pass through. In this embodiment, the elastic element 400 is specifically a spring. It should be noted that the elastic element 400 in this embodiment is in a compressed state when installed, which has a tendency to make the hook lock 300 move downward. In this way, when the connecting post 200 is rotated so that the hook lock hole 210 corresponds to the slot 111, the locking part 310 will extend out from the slot 111.
[0055] When the pull tab 500 is located on the zipper engagement plane, that is, when the locking part 310 of the hook lock 300 is exactly aligned with the slot 111, the elastic element 400 will extend out of the slot 111 to lock the zipper head. When the pull tab 500 rotates to the left or right, it will drive the connecting post 200 to rotate, which in turn will drive the hook lock 300 to rotate, thereby causing the locking part 310 to deviate from the slot 111, thus making the zipper unlocked. With this setting, the hook lock 300 can be controlled to rotate by rotating the pull tab 500 of the zipper head. When the zipper rotates, the hook lock 300 will not be in contact with the zipper teeth, eliminating the friction between the hook lock 300 and the zipper teeth, thereby reducing the risk of the hook lock 300 scratching the zipper teeth.
[0056] Of course, in this embodiment, when the hook lock 210 corresponds to the slot 111, the pull tab 500 is exactly parallel to the third direction. The angle between the line connecting the hook lock 210 and the axis of the connecting post 200 and the length direction of the pull tab 500 can be adjusted according to the actual situation. This article does not make specific limitations. As long as the connecting post 200 can be rotated to a specific angle so that the hook lock 210 corresponds to the slot 111, this angle is the locking angle of the zipper head.
[0057] Preferably, one end of the connecting column 200 is provided with a through hole 220 for passing through the crossbar 510, and the other end is provided with a cylindrical buckle 230. The upper wing plate 110 is provided with a buckle cavity 112 for cooperating with the cylindrical buckle 230 on the side opposite to the lower wing plate 120.
[0058] Specifically, such as Figure 9 and 10 The top of the connecting post 200 is provided with a through hole 220. The diameter of the through hole 220 is close to, but slightly larger than, the diameter of the crossbar 510. When the cylindrical crossbar 510 is inserted into the hole, it can rotate freely around its own axis. A cylindrical buckle 230 is connected to the bottom of the connecting post 200. Correspondingly, a buckle cavity 112 is provided on the upper side of the upper wing plate 110. Specifically, as shown... Figure 7 As shown, the cylindrical buckle 230 can be directly snapped into the buckle cavity 112, wherein the inlet size of the buckle cavity 112 is smaller than the size of the cylindrical buckle 230, thereby preventing the cylindrical buckle 230 from detaching from the buckle cavity 112.
[0059] Furthermore, the slot 111 is disposed on the bottom surface of the snap-fit cavity 112, and the slot 111 is located on the side of the snap-fit cavity 112 with its axis pointing in the third direction.
[0060] Specifically, such as Figures 5 to 7As shown, the slot 111 is disposed through the bottom surface of the buckle cavity 112, that is, the slot 111 passes through the upper wing plate 110. This arrangement allows the locking part 310 to extend out and directly act on the zipper, thereby locking the zipper head.
[0061] Furthermore, the hook lock insertion hole 210 is located on the end face of the cylindrical buckle 230, and the line connecting the hook lock insertion hole 210 and the cylindrical buckle 230 is perpendicular to the axis of the through hole 220.
[0062] Correspondingly, in this embodiment, the hook lock insertion hole 210 is set at an off-center position on the bottom surface of the cylindrical buckle 230. Preferably, the straight line connecting the axis of the hook lock insertion hole 210 and the axis of the cylindrical buckle 230 is perpendicular to the axis of the through hole 220. This setting ensures that when the hook lock insertion hole 210 corresponds to the slot 111, the pull tab 500 is exactly parallel to the zipper.
[0063] Preferably, the hook lock 300 further includes a mounting sleeve 320, which is installed inside the hook lock insertion hole 210 and moves along a first direction. The locking part 310 is connected to the end of the mounting sleeve 320 away from the connecting post 200. The mounting sleeve 320 is provided with a receiving channel 321 for installing the elastic member 400. The elastic member 400 is located in the receiving channel 321, with one end abutting against the connecting post 200 and the other end abutting against the locking part 310.
[0064] Specifically, such as Figures 11 to 13 As shown, the hook lock 300 includes two parts: a mounting sleeve 320 that inserts into the hook lock socket 210, and a locking part 310 that can pass through the slot 111. The mounting sleeve 320 is a hollow structure, and its outer diameter is the same as the inner diameter of the hook lock socket 210. When the hook lock 300 is inserted into the hook lock socket 210, the hook lock 300 can rotate freely around its own axis. The inside of the mounting sleeve 320 is provided with a receiving channel 321 for installing the elastic element 400. The diameter of the receiving channel 321 is the same as that of the elastic element 400. When the elastic element 400 is inserted to the bottom of the receiving channel 321, the hook lock 300 can be inserted into the hook lock socket 210. One end of the elastic element 400 can contact the top of the hook lock socket 210, and the other end can contact the locking part 310, so that the hook lock 300 has a downward tendency to move.
[0065] Preferably, the slot 111 has a tapering opening away from the first direction.
[0066] Specifically, such as Figure 7As shown, in order to facilitate the locking part 310 to extend easily from the slot 111, the opening size of the top surface of the slot 111 is larger than the opening size of its bottom surface; in addition, this setting makes it easy and effortless to pull the locking part 310 out of the slot 111 when the connecting post 200 rotates; therefore, the two side walls of the slot 111 in this embodiment are provided with smooth arc surfaces.
[0067] Preferably, the locking part 310 is a tapered structure that gradually narrows away from the first direction.
[0068] In this embodiment, the locking part 310 is preferably a tapered structure that tapers downwards. Correspondingly, the slot 111 is also set as a tapered groove with the same tapered angle as the locking part 310. With this configuration, when the tapered locking part 310 of the hook lock 300 is inserted into the bottom of the tapered slot 111, the tapered locking part 310 of the hook lock 300 can pass through the tapered slot 111 and half of the tapered locking part 310 of the hook lock 300 can be exposed. Furthermore, the inner edge of the tapered slot 111 is chamfered so that the tapered locking part 310 of the hook lock 300 can slide freely left and right in the tapered slot 111. And because the slot 111 is a tapered structure that tapers downwards, the size of the tapered part is inconsistent at the top and bottom, so that the locking part 310 cannot move in the vertical direction.
[0069] Preferably, the lock cylinder 121 and the lower wing plate 120 are an integral structure, and the upper wing plate 110 is provided with a lock cylinder hole 113 that is interference-fitted with the lock cylinder 121.
[0070] Specifically, such as Figures 5 to 8 As shown, the lock cylinder 121 is located on the axis of symmetry of the lower wing plate 120, and the two are integral structures. Correspondingly, the upper wing plate 110 has a lock cylinder hole 113 at the same position. The size of the lock cylinder hole 113 is similar to that of the lock cylinder 121, as long as the two meet the interference fit.
[0071] Preferably, the cylindrical buckle 230 and the buckle cavity 112 are interference fit to prevent the connecting column 200 from shaking when no external force is applied.
[0072] The diameter of the cylindrical buckle 230 is the same as the diameter of the buckle cavity 112, and the two are mutually fitted. When the cylindrical buckle 230 is inserted into the bottom of the buckle cavity 112, the cylindrical buckle 230 can rotate freely without falling off, and it can also prevent the cylindrical buckle 230 from shaking randomly in the buckle cavity 112.
[0073] Preferably, the locking part 310 is an arc-shaped structure that gradually narrows away from the first direction.
[0074] In another embodiment, the locking mechanism can be configured as an arc-shaped structure, and the corresponding slot 111 also needs to be adjusted.
[0075] In summary, this application provides a rotary lock zipper head, the specific assembly steps of which are as follows:
[0076] First, insert the cylindrical crossbar 510 on the pull tab 500 into the cylindrical through hole 220 on the connecting post 200. At this time, the pull tab 500 and the connecting post 200 are connected to each other through the crossbar 510 and the through hole 220. Second, insert the elastic element 400 into the bottom of the receiving channel 321. Further, insert the hook lock 300 with the elastic element 400 inserted into the bottom of the hook lock insertion hole 210 of the connecting post 200, so that the elastic element 400 contacts the bottom of the hook lock insertion hole 210. At this time, the components pull tab 500, connecting post 200 and hook lock 300 are connected together. Then, insert the cylindrical buckle 230 of the connecting post 200 with the hook lock 300 into the clip on the upper wing plate 110. At the bottom of the latch cavity 112, the locking part 310 of the hook lock 300 is inserted into the bottom of the conical slot 111 under the action of the elastic element 400, and the cylindrical buckle 230 completely passes through the latch cavity 112. At this time, the conical locking part 310 of the hook lock 300 passes through the conical slot 111 and is exposed. At this time, the component pull tab 500, the connecting post 200, the hook lock 300 and the upper wing plate 110 are connected together. Next, the lock cylinder 121 on the lower wing plate 120 is inserted into the lock cylinder hole 113 on the upper wing plate 110. At this time, the pull tab 500, the connecting post 200, the hook lock 300, the upper wing plate 110 and the lower wing plate 120 are connected together. Finally, press Figure 1 As shown, when the pull tab 500 is rotated horizontally around the axis of the connecting post 200, rotating 90° to the left or right, the connecting post 200 causes the hook lock 300 to slide to the right or left within the conical slot 111. At this time, the locking part 310 at the bottom of the hook lock 300 is not exposed at the bottom of the conical slot 111. Thus, the entire zipper head is in an unlocked state and can slide freely on the zipper without scratching the zipper teeth.
[0077] It should be noted that in this application, the pull tab 500, connecting post 200, hook lock 300, upper wing plate 110, and lower wing plate 120 can be made of, but are not limited to, metal alloys and plastic polymer materials. Further options include copper alloys, zinc alloys, stainless steel, aluminum alloys, titanium alloys, and sintered powder metallurgy metals. In addition, the polymer plastic material can be polyoxymethylene, polyethylene, polyamide, and polyurethane materials, as well as modified versions of these polymers. Modified materials can include carbon fiber and glass fiber. Furthermore, the elastic element 400 can be a component with a telescopic function.
