[0035] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and 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 direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application.

[0036] The present application provides a magnetic combination pull tab, comprising: a pull tab body 1, a magnetic component 3 and a functional component 4;

[0037] The pull tab body 1 is used to connect to the slider base, and a limiting hole 2 is provided on the pull tab body 1;

[0038] The magnetic attraction component 3 is arranged in the limiting hole 2;

[0039] The surface of the functional part 4 is conformal to the surface of the pull-tab body 1 , and a magnetic hook structure 5 is provided on the surface of the functional part 4 . The hook structure 5 is used to be inserted into the limiting hole 2 to achieve the connection between the pull-tab body 1 and the functional part 4 .

[0040] For details, please refer to the attached Figure 1 To the attached Figure 4 The present application provides two types of magnetic combination pull tabs. The following is the first type of magnetic combination pull tab. The pull tab body 1 is a block structure. The limiting hole 2 is set through the plate surface of the pull tab body 1. The magnetic attraction component 3 is set on the side of the limiting hole 2 away from the functional part 4 to ensure that the magnetic attraction component 3 can always play a magnetic role on the hook structure 5 before the hook structure 5 enters the limiting hole 2. Please refer to the attached Figure 1 To the attached Figure 4 The magnetic component 3 is arranged at the lower side of the limiting hole 2, and the hook head of the hook-shaped structure 5 is also arranged downward, which can reduce the overall space occupied by the structure of the magnetic component 3 and the limiting hole 2, thereby reducing the length, width and thickness of the pull tab, making the overall volume of the pull tab smaller and thinner. For the hook-shaped structure 5, the end of the hook head of the hook-shaped structure 5 is generally set as a magnetic part to maintain magnetic attraction. In addition, the surface of the functional part 4 is conformal to the surface of the pull tab body 1. When the functional part 4 is fully engaged with the pull tab body 1, the functional part 4 is completely fitted with the pull tab body 1. The degree of fit between the two can also be used to intuitively judge whether the two are successfully engaged. The entire installation process is fast and simple, which greatly improves the production and installation efficiency of the pull tab.

[0041] Optionally, a magnet may be provided at the end of the hook-shaped structure 5 , and the magnetic attraction component 3 may also be made of a magnet, which has relatively low cost and is convenient for mass production.

[0042] On the basis of the above embodiment, a guide curved surface 10 is provided on the inner side wall of the limiting hole 2 so that the aperture of the limiting hole 2 gradually decreases from the functional component 4 to the magnetic attraction component 3 .

[0043] Specifically, the limiting hole 2 is as shown in the attached Figure 2 As shown, it is generally a square hole, and the upper, left and right inner walls of the limiting hole 2 are all provided with guide curved surfaces 10. The guide curved surfaces 10 can make the aperture of the limiting hole 2 gradually decrease from the functional part 4 toward the back of the pull-tab body 1, so that the hook-shaped structure 5 can be installed more smoothly and the positioning can be more accurate.

[0044] On the basis of the above embodiment, a groove is provided in the limiting hole 2 , the magnetic component 3 is provided in the groove, and a limiting step 6 for engaging with the hook structure 5 is provided on the magnetic component 3 .

[0045] Specifically, a groove is provided directly below the limiting hole 2, i.e., in the portion where the guide curved surface 10 is not provided. The magnetic component 3 is placed in the groove, and the magnetic component 3 is embedded under the limiting hole 2 by wrapping the magnetic component 3 with an injection molding layer. This ensures that the magnetic component 3 cannot be separated from the injection molding layer, thus preventing the magnetic component 3 from falling off. At the same time, the injection molding layer also protects the magnetic component 3 and reduces damage to the magnetic component 3.

[0046] Optionally, the pull-tab body 1 may be a plastic part, that is, the entire pull-tab body 1 and the magnetic attraction component 3 may be integrally formed by injection molding, which is convenient for mass production.

[0047] In some embodiments, there are three limiting holes 2 and two hook-shaped structures 5 . The three limiting holes 2 are arranged in an inverted triangle on the pull-tab body 1 , and the two upper hook-shaped structures 5 are arranged corresponding to the two limiting holes 2 .

[0048] Specifically, the second magnetic combination pull tab provided in this application has three limiting holes 2 set on its pull tab body 1. Figure 5 With attached Figure 6 Two hook-shaped structures 5 are provided on the functional part 4, and the two limiting holes 2 on the upper side are arranged side by side, and the corresponding two hook-shaped structures are also arranged side by side. For these two limiting holes 2, both limiting holes 2 are square holes. After the two hook-shaped structures 5 are inserted into the limiting holes 2, the stability of the connection between the functional part 4 and the pull-tab body 1 can be ensured.

[0049] On the basis of the above embodiment, a mounting hole 7 is provided on the surface of the functional part 4 facing the pull-tab body 1 , and a magnetic block 8 is provided in the mounting hole 7 . The magnetic block 8 is protruded from the surface of the functional part 4 .

[0050] Specifically, a magnetic component 3 is arranged in the limiting hole 2 below the pull-tab body 1, and a mounting hole 7 is arranged on the functional part 4. The mounting hole 7 is arranged corresponding to the limiting hole 2 on the lower side. A magnetic block 8 is arranged in the mounting hole 7. The magnetic block 8 and the magnetic component 3 are magnetically attracted to each other. The magnetic block 8 protrudes from the surface of the functional part 4. During installation, the magnetic block 8 can be inserted into the limiting hole 2 to fit with the magnetic component 3 and complete the connection between the pull-tab body 1 and the functional part 4.

[0051] Based on the above embodiment, the limiting hole 2 on the lower side includes a cylindrical section and a frustum-shaped section. The magnetic component 3 is a cylindrical structure and is arranged in the cylindrical section. The frustum-shaped section is connected to the cylindrical section. The diameter of the frustum-shaped section gradually increases in the direction of the magnetic component 3 toward the functional part 4.

[0052] Specifically, the limiting hole 2 on the lower side includes two sections of structure, one section is a cylindrical section for installing the magnetic attraction component 3, and the other section is a truncated cone section. The aperture of the truncated cone section gradually increases from the magnetic attraction component 3 toward the magnetic block 8. When realizing the connection between the pull-tab body 1 and the functional part 4, the two hook-shaped structures 5 are firstly connected with the two limiting holes 2 on the upper side. There is a distance between the lower magnetic block 8 and the limiting hole 2 initially, and then it slides along the side wall of the truncated cone section until it fits the magnetic attraction component 3.

[0053] In some embodiments, the first end of the functional part 4 is an arc-shaped end face, the middle part of the functional part is a rectangular structure, the first end of the functional part 4 transitions smoothly with the middle part thereof, and the pull-tab body 1 is provided with a conformal surface that matches the first end and middle part of the functional part 4.

[0054] Specifically, for the two magnetic combination pull tabs, the first end of the functional part 4, that is, the upper end, is provided with an arc-shaped end surface, the middle part of which is a rectangular parallelepiped, and the corresponding pull tab body 1 is provided with an end surface that conforms to the functional part 4, so that the pull tab body 1 and the functional part 4 are buckled together to form a pull tab with no protrusions on the surface.

[0055] On the basis of the above embodiment, a groove is provided at the second end of the functional part 4 , and a fixed shaft is provided in the groove, and the fixed shaft is used to install the pull tab.

[0056] Specifically, a groove is provided at the second end of the functional part 4, and a fixed shaft in the groove can be installed with a detachable pull tab to form the entire pull tab. For the pull tab, a cloth tape or a rope tape can be selected. When a cloth tape is selected, a special logo can be set on its surface to enhance the sense of design.

[0057] On the basis of the above embodiment, a through hole 9 is provided on the pull-tab body 1 , and the through hole 9 is used to realize the connection between the pull-tab body 1 and the slider base.

[0058] Specifically, a through hole 9 is provided on the pull tab body 1, which is connected to the slider base through the through hole 9, so that the pull tab body 1, the functional part 4, the slider base and the pull tab can form the entire slider, ensuring the structural integrity.

[0059] In addition to the above-mentioned magnetic combination pull tab, the present invention also provides a zipper including the magnetic combination pull tab disclosed in the above-mentioned embodiment. For the structures of other parts of the zipper, please refer to the prior art and will not be described in detail herein.
