Description

Technical Field

[0001] The utility model relates to the technical field of zippers, in particular to a slider structure and a zipper. Background Art

[0002] The zipper slider is an important part of the zipper, usually made of metal, plastic or other materials. Its main function is to provide guidance and connection during the zipper operation, ensuring that the zipper can open and close smoothly.

[0003] When existing double-sided lock slider bases are combined with a cord loop, the cord loop causes a change in the point of force, causing the slider to be lifted at a different angle than when held for use. This results in a travel delay. Specifically, when the cord is initially lifted, the slider remains flat, unloaded, and unable to exert force on the spring, resulting in reduced slider unlocking sensitivity. In this case, normal zipper zipping and closing actions make it difficult to unlock the slider, preventing the zipper from being opened or closed, and reducing the user experience. Therefore, how to adjust the slider unlocking threshold to improve the slider unlocking sensitivity and enhance the user experience is a technical problem that needs to be urgently addressed by those skilled in the art. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] In order 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 implementation methods.

[0033] The utility model provides a slider structure and a zipper, which improves the slider unlocking sensitivity by adjusting the stroke of lifting the pull tab 20 to lift the horse hook 30 to completely unlock the slider, thereby achieving the purpose of enhancing user experience.

[0034] Please refer to Figures 1 to 5 The slider structure provided by the present invention includes a slider body 10, a pull tab 20 and a horse hook 30; the slider body 10 is fixedly provided with a connecting seat 14; the pull tab 20 is connected to the connecting seat 14, and the pull tab 20 is rotatably provided on the slider body 10 through the connecting seat 14, and one end of the pull tab 20 is penetrated by a pull tab hole 21, and the pull tab hole 21 is provided with a connecting protrusion 22, and the length of the connecting protrusion 22 along the extension direction of the pull tab 20 is recorded as T1; both ends of the horse hook 30 are plugged into the slider body 10, and the horse hook 30 is elastic. When the pull tab 20 rotates, the connecting protrusion 22 contacts the horse hook 30 to overcome the elastic force of the horse hook 30 to unlock the slider structure. The length of the part where the horse hook 30 and the connecting protrusion 22 cooperate and contact is recorded as L1, and the ratio of T1 to L1 is 1:1.2 ~ 1:1.4.

[0035] When the pull tab 20 is not raised, that is, in a horizontal state, the connecting protrusion 22 of the pull tab 20 does not touch the horse hook 30. The two ends of the horse hook 30 are inserted into the pull body 10. Under the action of its own elastic force, it abuts against the pull body 10 to achieve the connection between the horse hook 30 and the pull body 10. One end of the horse hook 30 is inserted into the gap between the teeth, so that the slider can be locked on the zipper and is in a locked state. At this time, the slider cannot slide, that is, it cannot guide the closing or opening of the slider structure by pulling the slider structure. When in use, the pull tab 20 is lifted to a certain angle so that the connecting protrusion 22 contacts the horse hook 30, and the connecting protrusion 22 pushes up the horse hook 30, thereby achieving unlocking. When the ratio of the length of the connecting protrusion 22 along the extension direction of the pull 20 and the length of the part where the horse hook 30 and the connecting protrusion 22 cooperate and contact is 1:1.2 ~ 1:1.4, when the pull tab 20 is lifted at a smaller angle, the connecting protrusion 22 of the pull tab 20 can contact with the horse hook 30 to push up the horse hook 30, and the unlocking of the slider structure is more sensitive, thereby improving the user experience.

[0036] Please refer to Figures 5 and 6 In some embodiments, the length T1 of the connecting protrusion 22 along the extension direction of the pull tab 20 is 1.9 mm, and the length L1 of the portion where the hook 30 contacts the connecting protrusion 22 is 2.6 mm. At this time, the ratio of T1 to L1 is 1:1.37. When the pull tab 20 is lifted at a small angle, the connecting protrusion 22 of the pull tab 20 can contact the hook 30 and lift the hook 30, and the slider structure is sensitive to unlocking.

[0037] Please refer to Figure 5 and Figure 7 In some embodiments, the length T1 of the connecting protrusion 22 along the extension direction of the pull tab 20 is 1.7 mm, and the length L1 of the portion where the hook 30 contacts the connecting protrusion 22 is 2.3 mm. At this time, the ratio of T1 to L1 is 1:1.35. When the pull tab 20 is lifted at a small angle, the connecting protrusion 22 of the pull tab 20 can contact the hook 30 and lift the hook 30, and the slider structure is unlocked sensitively.

[0038] Please refer to Figure 5 and Figure 8 In some embodiments, the length T1 of the connecting protrusion 22 along the extension direction of the pull tab 20 is 1.8 mm, and the length L1 of the portion where the hook 30 contacts the connecting protrusion 22 is 2.4 mm. At this time, the ratio of T1 to L1 is 1:1.33. When the pull tab 20 is lifted at a small angle, the connecting protrusion 22 of the pull tab 20 can contact the hook 30, thereby lifting the hook 30, and the slider structure is sensitive to unlocking.

[0039] When the ratio of the length of the connecting protrusion 22 along the extending direction of the pull tab 20 to the length of the portion where the hook 30 contacts the connecting protrusion 22 is outside the range of 1:1.2 to 1:1.4, the unlocking sensitivity of the slider structure is reduced. Figure 5 and Figure 9 For example, when the length T1 of the connecting protrusion 22 along the extension direction of the pull tab 20 is 1.7 mm, and the length L1 of the portion where the hook 30 contacts the connecting protrusion 22 is 2.6 mm, the ratio between the two is 1:1.53. The pull tab 20 needs to rotate a larger angle before the connecting protrusion 22 can lift the hook 30 and unlock the slider structure.

[0040] Please refer to Figures 1 to 5The hook 30 is curved and includes a front end 301, a first middle portion 302, a second middle portion 303, a third middle portion 304, and a rear end 305, which are connected in sequence. The portion of the hook 30 that contacts the connecting protrusion 22 is the third middle portion 304. When the pull tab 20 is raised to a certain angle, the connecting protrusion 22 of the pull tab 20 can contact the third middle portion 304 of the hook 30. The connecting protrusion 22 lifts the hook 30 through the third middle portion 304, and the end of the hook 30 disengages from the gap between the teeth, thereby unlocking the slider structure.

[0041] Please refer to Figures 1 to 5 The front end 301 is smoothly connected to the first middle portion 302, the first middle portion 302 is smoothly connected to the second middle portion 303, the second middle portion 303 is smoothly connected to the third middle portion 304, and the third middle portion 304 is smoothly connected to the rear end 305. This smooth connection method has the following advantages: 1. It reduces stress concentration, increases the strength and durability of the connection, and improves the structural strength and service life of the harness 30; 2. It reduces wear and impact during use, installation, removal, and transportation, reducing maintenance and replacement costs; 3. It makes the harness 30 look smoother and more comfortable, improving its aesthetics.

[0042] Please refer to Figures 1 to 5 The pull body 10 includes a first wing plate 11 and a second wing plate 12. The second wing plate 12 is located below the first wing plate 11. The first wing plate 11 and the second wing plate 12 are connected by a connecting column 13. A connecting seat 14 is fixed to the first wing plate 11. The connecting seat 14 is located on the side of the first wing plate 11 away from the second wing plate 12. The connecting seat 14 has a through hole. The pull tab 20 is rotatably connected to the connecting seat 14 through the through hole of the connecting seat 14, so that the pull tab 20 can be rotatably mounted on the pull body 10. There are two connecting seats 14, and the two connecting seats 14 are arranged at intervals.

[0043] Among them, the first wing plate 11 and the second wing plate 12 mainly play a limiting role, so that the teeth can move in the space between the first wing plate 11 and the second wing plate 12 without disengaging, and the first wing plate 11 and the second wing plate 12 are generally arranged in parallel, through such an arrangement, so that the teeth can slide smoothly in the space formed by the first wing plate 11 and the second wing plate 12. The function of the connecting column 13 is to close or separate the chain. The connecting column 13 is an indispensable part of the slider structure, generally a columnar structure. The connecting column 13 is arranged between the head of the first wing plate 11 and the head of the second wing plate 12, and the connecting column 13 is located on the same side of the first wing plate 11 and the second wing plate 12, that is, the connecting column 13 is located at the front end of the slider structure, and the connecting column 13 should be arranged at the central axis of the first wing plate 11 and the second wing plate 12. Through such an arrangement, it is ensured that the space on both sides of the first wing plate 11 and the second wing plate 12 is symmetrical, thereby ensuring that the slider slides smoothly.

[0044] Please refer to Figures 1 to 5 The first wing plate 11 is penetrated by a horse hook hole 111 , the rear end portion 305 of the horse hook 30 is inserted into the horse hook hole 111 , the connecting column 13 is penetrated by a receiving hole 131 , the front end portion 301 of the horse hook 30 is inserted into the receiving hole 131 . The horse hook 30 and the pull tab 20 are arranged above the first wing plate 11 of the pull body 10. When the horse hook 30 is arranged on the pull body 10, the front end portion 301 of the horse hook 30 is inserted into the receiving hole 131, and the rear end portion 305 of the horse hook 30 is inserted into the horse hook hole 111. Under the action of the elastic force of the horse hook 30 itself, the front end portion 301 and the rear end portion 305 of the horse hook 30 are abutted against the wall surface of the receiving hole 131 of the pull body 10 and the wall surface of the horse hook hole 111 of the pull body 10, thereby achieving the fixation of the horse hook 30. When the pull tab 20 is not lifted, the connecting protrusion 22 of the pull tab 20 does not touch the horse hook 30, and the rear end portion 305 of the horse hook 30 can be inserted into the gap between the teeth between the first wing plate 11 and the second wing plate 12, so that the slider structure is in a locked state, and the slider structure cannot slide at this time. After the pull tab 20 is lifted to a certain angle, the connecting protrusion 22 of the pull tab 20 contacts the third middle portion 304 of the hook 30, and the connecting protrusion 22 lifts the hook 30 through the third middle portion 304, and the rear end portion 305 of the hook 30 disengages from the gap between the teeth, thereby unlocking the slider structure.

[0045] In addition, please refer to Figures 1 to 5A card slot 132 is provided in the accommodating hole 131, and the card slot 132 is provided near the side of the second wing plate 12. When the front end portion 301 of the horse hook 30 is inserted into the accommodating hole 131, the starting end of the front end portion 301 is engaged in the card slot 132. Through such a setting, the front end portion 301 of the horse hook 30 can be reliably installed in the accommodating hole 131, and the pull tab 20 is lifted to a certain angle so that the connecting protrusion 22 contacts the third middle portion 304 of the horse hook 30. When the horse hook 30 is lifted by the third middle portion 304, the front end portion 301 of the horse hook 30 remains basically stationary, and the rear end portion 305 of the horse hook 30 moves upward along the horse hook hole 111, disengages from the gap between the teeth, and the slider structure is unlocked. After the zipper is pulled or closed by the slider structure, the pull tab 20 is rotated so that the pull tab 20 is in an unraised state, that is, in a horizontal state. The connecting protrusion 22 of the pull tab 20 is no longer in contact with the third middle portion 304 of the hook 30. Under the elastic action of the hook 30 itself, the rear end portion 305 of the hook 30 moves downward along the hook hole 111 and re-enters the gap between the teeth to lock the slider structure.

[0046] Please refer to Figure 1 The end of the pull tab 20 away from the pull tab hole 21 is provided with a connecting hole 23 for connecting the pull tab 20 to a drawstring. One end of the drawstring is fixed to one end of the pull tab 20 through the connecting hole 23. By pulling the drawstring to drive the pull tab 20, the slider structure is unlocked, and the slider structure is pulled along the teeth to achieve the zipper opening or closing.

[0047] In the slider structure provided by the present invention, the ratio of the length of the connecting protrusion 22 along the extension direction of the pull tab 20 to the length of the portion where the hook 30 cooperates with the connecting protrusion 22 is 1:1.2 to 1:1.4. When the pull tab 20 is lifted at a small angle, the connecting protrusion 22 of the pull tab 20 can contact the hook 30, thereby lifting the hook 30 to achieve unlocking. The unlocking of the slider structure is more sensitive, thereby improving the user experience.

[0048] In addition to the slider structures disclosed in the aforementioned embodiments, the present invention also provides a zipper including the aforementioned slider structure. The zipper further comprises two zipper tapes, wherein two rows of teeth are arranged in a staggered pattern. The slider structure clamps the teeth on both sides. After the slider structure is unlocked, the slider structure can be engaged or disengaged by pulling the pull tab 20 to slide the slider structure along the teeth. The zipper can produce the same technical effects as the slider structure.

[0049] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.

[0050] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the present invention.
