[0023] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0024] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0025] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., 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 application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0027] The zipper pull is the core operating component of the zipper assembly. The zipper pull and the zipper teeth on the zipper belt cooperate through a mechanical structure. The movement of the zipper pull relative to the zipper controls the engagement and disengagement of the zipper teeth, thereby realizing the opening and closing function of the zipper assembly.

[0028] However, in related technologies, when the zipper tab rests against the surface of the zipper body, the surface of the zipper body will lift the zipper tab, resulting in a larger thickness of the zipper head.

[0029] To address the aforementioned technical problems, embodiments of this application provide a zipper pull, a zipper assembly using the zipper pull, and a zipper product using the zipper pull.

[0030] The zipper provided in this embodiment has a through groove on the surface of the first wing plate, and part of the zipper tab can be accommodated in the through groove, thereby preventing the zipper tab from being lifted up, thus reducing the thickness of the zipper and giving the zipper a thin and light appearance.

[0031] Please refer to the following: Figure 1 , Figure 2 and Figure 3 The slider 100 provided in the embodiments of this application will now be described.

[0032] It should be noted that the first direction in the following text is the z-direction shown in the figure, the second direction in the following text is the x-direction shown in the figure, and the third direction in the following text is the y-direction shown in the figure.

[0033] The slider 100 provided in this application embodiment includes a first wing plate 10, a second wing plate 20, and a mechanism 30.

[0034] The first wing plate 10 and the second wing plate 20 are parallel to each other and spaced apart along the first direction z, and the mechanism 30 is connected between the first wing plate 10 and the second wing plate 20.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the first wing plate 10 and the second wing plate 20 both extend parallel to the xOy plane shown in the figure, and the orthographic projection of the first wing plate 10 in the first direction z coincides with the orthographic projection of the second wing plate 20 in the first direction z. The first wing plate 10 and the second wing plate 20 are arranged at intervals so that the zipper teeth can be movably assembled between the first wing plate 10 and the second wing plate 20.

[0036] The mechanism 30 extends along the first direction z and is connected between the first wing plate 10 and the second wing plate 20. A Y-shaped channel is formed between the mechanism 30, the first wing plate 10 and the second wing plate 20. When the two chains of the zipper assembly move relative to the mechanism 30 along the Y-shaped channel, the chain teeth of the two chains can switch between the engaged state and the disengaged state, thereby controlling the engagement state of the zipper assembly through the zipper head 100.

[0037] The first wing plate 10 has a protrusion 40 on the side opposite to the second wing plate 20 in the first direction z. The protrusion 40 has a through groove 44 that passes through the protrusion 40 along the second direction x, which is orthogonal to the first direction z. The protrusion 40 includes a crossbar 43 located on the side of the through groove 44 opposite to the first wing plate 10. The crossbar 43 is used to install the pull tab 50. The through groove 44 can accommodate at least part of the pull tab 50.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the protrusion 40 is located on the side of the first wing plate 10 facing away from the second wing plate 20 in the first direction z. The orthographic projection of the protrusion 40 in the first direction z is located inside the outline of the orthographic projection of the first wing plate 10 in the first direction z. The through groove 44 passes through the protrusion 40 along the second direction x. The through groove 44 divides the protrusion 40 into two parts arranged along the third direction y. A crossbar 43 is formed on the side of the through groove 44 facing away from the first wing plate 10. The crossbar 43 extends along the third direction y and connects between the two parts of the protrusion 40.

[0039] like Figure 4 and Figure 5As shown, the pull tab 50 is for the user's fingers to hold and pull the pull head 100 to move. The pull tab 50 can be arranged around the crossbar portion 43, so that part of the pull tab 50 is accommodated in the through groove 44.

[0040] The beneficial effects of the zipper pull 100 provided in this application embodiment are as follows: Compared with the prior art, a portion of the pull tab 50 of the zipper pull 100 provided in this application embodiment can be accommodated in the through groove 44 between the crossbar portion 43 and the first wing plate 10, thereby preventing the protrusion 40 from lifting the pull tab 50 when it rests on the surface of the first wing plate 10, thus reducing the thickness of the zipper pull 100 and giving the zipper pull 100 provided in this application embodiment the advantage of having a smaller thickness.

[0041] In some embodiments provided in this application, the thickness of a portion of the protrusion 40 located on one side of the crossbar portion 43 in the second direction x gradually decreases in the first direction z along the second direction x away from the crossbar portion 43, and the thickness of a portion of the protrusion 40 located on the other side of the crossbar portion 43 in the second direction x gradually decreases in the first direction z along the second direction x away from the crossbar portion 43.

[0042] like Figure 2 As shown, the crossbar portion 43 is located at the point of maximum thickness of the protrusion 40, meaning that the distance between the crossbar portion 43 and the first wing plate 10 in the first direction z is greater than the distance between any other position of the protrusion 40 and the first wing plate 10, such as... Figure 2 As shown, the thickness of the protrusions 40 on both sides of the crossbar portion 43 in the second direction x gradually decreases to 0 along the second direction x away from the crossbar portion 43, making the outline of the protrusion 40 in the third direction y smooth and rounded, improving the smoothness of the outer outline of the zipper pull 100 provided in this application embodiment, and optimizing the user experience.

[0043] In addition, when the pull tab 50 is arranged parallel to the first wing plate 10, the protrusions 40 on both sides of the crossbar portion 43 in the second direction x can avoid the pull tab 50, further preventing the protrusions 40 from lifting the pull tab 50, thereby reducing the thickness of the pull head 100, so that the pull head 100 provided in this application embodiment has the advantage of a smaller thickness.

[0044] In some embodiments provided in this application, the crossbar portion 43 extends along a third direction y, which is orthogonal to the first direction z and the second direction x; Among them, the thickness of the portion of the protrusion 40 located on the third direction y of the crossbar portion 43 gradually decreases in the first direction z along the third direction y away from the crossbar portion 43, and the thickness of the portion of the protrusion 40 located on the other side of the crossbar portion 43 on the third direction y gradually decreases in the first direction z along the third direction y away from the crossbar portion 43.

[0045] like Figure 3 As shown, the crossbar portion 43 is located at the point of maximum thickness of the protrusion 40, meaning that the distance between the crossbar portion 43 and the first wing plate 10 in the first direction z is greater than the distance between any other position of the protrusion 40 and the first wing plate 10, such as... Figure 3 As shown, the thickness of the protrusions 40 on both sides of the crossbar portion 43 in the third direction y gradually decreases to 0 along the third direction y away from the crossbar portion 43, making the outline of the orthogonal projection of the protrusions 40 in the second direction x smooth and rounded, improving the smoothness of the outer contour of the zipper pull 100 provided in this application embodiment, and optimizing the user experience.

[0046] In addition, when the pull tab 50 is arranged parallel to the first wing plate 10, the protrusions 40 on both sides of the crossbar portion 43 in the third direction y can avoid the pull tab 50, further preventing the protrusions 40 from lifting the pull tab 50, thereby reducing the thickness of the pull head 100, so that the pull head 100 provided in this application embodiment has the advantage of a smaller thickness.

[0047] In some embodiments provided in this application, such as Figure 1 and Figure 2 As shown, the zipper 100 has a head end 001 and a tail end 002. The head end 001 is located at one end of the zipper 100 in the second direction x. The zipper 100 is used to move relative to the chain belt towards the head end 001 so that the chain belts engage with each other. The tail end 002 is located at the other end of the zipper 100 in the second direction x. The zipper 100 is used to move relative to the chain belt towards the tail end 002 so that the chain belts disengage from each other. The distance between the crossbar portion 43 and the head end 001 in the second direction x is less than the distance between the crossbar portion 43 and the tail end 002 in the second direction x.

[0048] In some embodiments provided in this application, the protrusion 40 includes a first pier 41 and a second pier 42, which are spaced apart on the first wing plate 10 along a third direction y. The third direction y is orthogonal to the first direction z and the second direction x. A through groove 44 is formed between the first pier 41 and the second pier 42, and a crossbar 43 connects the first pier 41 and the second pier 42. The surface of the first pier 41 facing the second pier 42 is parallel to the surface of the second pier 42 facing the first pier 41.

[0049] like Figure 2As shown, the first pier 41 has a first root 412 and a first top 411 at its two ends in the first direction z. The size of the first top 411 in the second direction x is the same as the size of the crossbar 43 in the second direction x. The crossbar 43 is located on the side of the first top 411 in the third direction y. The size of the first root 412 in the second direction x is the same as the size of the first wing plate 10 in the second direction x. One end of the first root 412 in the second direction x is connected to one end of the first wing plate 10 in the second direction x, and the other end of the first root 412 in the second direction x is connected to the other end of the first wing plate 10 in the second direction x.

[0050] like Figure 5 As shown, the second pier 42 has a second root 422 and a second top 412 at both ends in the first direction z. The size of the second top 412 in the second direction x is the same as the size of the crossbar 43 in the second direction x. The crossbar 43 is located on one side of the second top 412 in the third direction y. The size of the second root 422 in the second direction x is the same as the size of the first wing plate 10 in the second direction x. One end of the second root 422 in the second direction x is connected to one end of the first wing plate 10 in the second direction x, and the other end of the second root 422 in the second direction x is connected to the other end of the first wing plate 10 in the second direction x.

[0051] In some embodiments provided in this application, such as Figure 4 and Figure 5 As shown, the zipper 100 also includes a zipper tab 50, which includes an annular portion 51 and a handle portion 52. A portion of the annular portion 51 is accommodated in the through groove 44. The handle portion 52 is connected to the annular portion 51. The annular portion 51 is arranged around the crossbar portion 43 and is rotatable relative to the zipper tab 50.

[0052] In some embodiments provided in this application, such as Figure 5 As shown, the annular portion 51 includes a slot 511, which connects the inner edge of the annular portion 51 and the outer edge of the annular portion 51.

[0053] Therefore, by slotting 511, the annular part 51 can be snapped onto the outer periphery of the crossbar part 43 by snap-fit, simplifying the process of connecting the pull head 100 and the protrusion 40.

[0054] In some embodiments provided in this application, such as Figure 3 As shown, the second wing plate 20 is provided with a groove 21, which extends through the second wing plate 20 along the second direction x and is recessed on the surface of the second wing plate 20 on the side opposite to the first wing plate 10 in the first direction z.

[0055] In some embodiments, the orthographic projection of the sink 21 in the first direction z is located inside the orthographic projection of the through groove 44 in the first direction z, that is, the position of the sink 21 in the third direction y is located between the two ends of the through groove 44 in the third direction y.

[0056] Therefore, by setting the sink 21 to reduce the volume of the second wing plate 20, the pull head 100 provided in this embodiment of the application has the advantage of being thin and light.

[0057] The zipper assembly provided in this application includes a first zipper belt, a second zipper belt, and a zipper head 100, wherein the zipper head 100 is the zipper head 100 in any of the above embodiments. The zipper head 100 is movably mounted on the first zipper belt and the second zipper belt, and the movement of the zipper head 100 relative to the first zipper belt and the second zipper belt causes the zipper teeth of the first zipper belt and the zipper teeth of the second zipper belt to switch between an engaged state and a disengaged state.

[0058] The zipper pull 100 provided in this application embodiment has the advantages of a smooth appearance and a relatively thin overall shape, thereby improving the smoothness of the appearance of the zipper assembly provided in this application embodiment and enhancing the user experience.

[0059] The zipper product provided in this application embodiment includes the zipper head 100 in any of the above embodiments, or the zipper product provided in this application embodiment includes the zipper assembly in any of the above embodiments.

[0060] The zipper products provided in this application embodiment can be zipper products including clothing, shoes, bags, etc. The opening and closing of the inner cavity of the zipper product is controlled by the zipper assembly. Since the zipper head 100 provided in this application embodiment has the advantages of smooth appearance and thinness, the appearance of the zipper product provided in this application embodiment is improved and the user experience is enhanced.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
