[0032] Example 1

[0033] Please see Figures 1 to 3 As shown in the preferred embodiment of the present invention, a material point concealed pull tab 100 includes a pull tab seat 1 and an injection molded part 2. One end of the pull tab seat 1 has a first connecting part 11 for connecting with the pull head body 3, so as to hang the material point concealed pull tab 100 on the pull head body 3 using the first connecting part 11. The other end of the pull tab seat 1 has a second connecting part 12. The connecting end of the injection molded part 2 is connected to the second connecting part 12. Specifically, the connecting end of the injection molded part 2 is connected to the front side of the second connecting part 12. The end face of the connecting end of the injection molded part 2 forms a feeding point 21. The second connecting part 12 is provided with a shielding protrusion 13 for shielding the feeding point 21, so as to hide the feeding point 21 and avoid the feeding point 21 from being exposed to the outside and affecting the overall appearance.

[0034] Because injection molded parts all have a feeding point after injection molding, existing pull tabs expose this feeding point, affecting the overall appearance. Therefore, this invention forms a feeding point 21 on the end face where the injection molded part 2 connects to the pull tab seat 1. Simultaneously, a shielding protrusion 13 is provided on the second connecting part 12 of the pull tab seat 1 to conceal the feeding point 21, effectively hiding it and ensuring a more aesthetically pleasing pull tab.

[0035] It should be noted that: the end of the zipper body 3 with the chain branch is defined as the front end, and the end away from the chain branch is defined as the rear end. In this utility model, the front specifically refers to the side facing away from the zipper body 3 after the material point hidden pull tab 100 is laid flat towards the rear end. In this utility model, the back specifically refers to the side facing the zipper body 3 after the material point hidden pull tab 100 is laid flat towards the rear end.

[0036] In a preferred embodiment of the present invention, the shielding protrusion 13 has a shielding plane 131 on the side facing the injection molded part 2, and the end face of the connecting end of the injection molded part 2 is adjacent to or attached to the shielding plane 131, so as to better hide the feeding point 21 of the end face of the connecting end of the injection molded part 2.

[0037] In a preferred embodiment of this invention, limiting protrusions 121 are provided on both sides of the front of the second connecting portion 12, and the limiting protrusions 121 form a limiting plane 122 on the side facing the injection molded part 2; a blocking protrusion 13 is provided on the front of the second connecting portion 12, and the two ends of the blocking protrusion 13 are connected to the limiting protrusions 121 on both sides as a whole, and the height of the limiting protrusion 121 is less than the height of the blocking protrusion 13. This invention, by providing limiting protrusions 121 with limiting planes 122 on both sides of the front of the second connecting portion 12, enables the limiting protrusions 121 to limit the sides of the injection molded part 2 after the connecting end of the injection molded part 2 is assembled with the front of the second connecting portion 12, thereby improving the stability of the injection molded part 2 during use.

[0038] In a preferred embodiment of this utility model, in order to facilitate manufacturing and ensure overall strength, the blocking protrusion 13, the limiting protrusion 121 and the pull tab seat 1 are integrally cast.

[0039] In one specific embodiment of this utility model, the pull tab seat 1 is a zinc alloy casting. Of course, the above is only one specific embodiment of this utility model, but it is not limited to this; in specific implementations, it can also be cast from other metal materials.

[0040] In a preferred embodiment of the present invention, the height of the blocking protrusion 13 is greater than or equal to the thickness of the injection molded part 2, ensuring that the blocking protrusion 13 can reliably completely block the feed point 21 on the injection molded part 2.

[0041] In a preferred embodiment of the present invention, the back side of the connecting end of the injection molded part 2 and the front side of the second connecting part 12 are fastened together by a snap-fit ​​structure 4, so as to use the snap-fit ​​structure 4 to snap-fit ​​together the two different materials of the injection molded part 2 and the pull tab seat 1.

[0042] In a preferred embodiment of the present invention, the clamping structure 4 includes a clamping groove 41 and a clamping protrusion 42. The clamping groove 41 extends from the front to the back of the second connecting part 12, and the clamping protrusion 42 is integrally formed on the back of the connecting end of the injection molded part 2. In a specific implementation of this invention, the clamping groove 41 gradually decreases in size from top to bottom and then gradually increases in size. The clamping protrusion 42 includes a clamping post 421 connected to the back of the injection molded part 2 and a limiting block 422 located at the free end of the clamping post 421. The limiting block 422 has a structure that gradually increases in size from bottom to top, so as to clamp the clamping protrusion 42 into the clamping groove 41. The size of the clamping post 421 is smaller than the size of the clamping groove 41, and the size of the limiting block 422 is slightly larger than the size of the clamping groove 41. During assembly, the clamping protrusion 42 needs to be pressed into the clamping groove 41 from the front of the second connecting part 12, and the limiting block 422 of the clamping protrusion 42 passes through the clamping groove 41 and enters the back of the second connecting part 12. The limiting block 422 is used to limit the connecting end of the injection molded part 2, ensuring that the injection molded part 2 will not automatically detach from the front of the second connecting part 12 during use.

[0043] In a preferred embodiment of this invention, the front surface of the injection molded part 2 is sequentially formed with a first plane 22, a slope 23, and a second plane 24 from the connecting end to the free end. The second plane 24 is lower than the first plane 22, meaning that the thickness of the injection molded part 2 at the position corresponding to the second plane 24 is less than the thickness at the position of the first plane 22. This facilitates the user to grasp the injection molded part 2 from the position of the second plane 24 and perform a pulling operation. Furthermore, the second plane 24 has several openings 241 extending to the back surface. By creating openings 241 on the second plane 24, this invention not only makes the overall shape of the hidden material point pull tab 100 more aesthetically pleasing but also increases the friction between the user's hand and the injection molded part 2, thereby facilitating a smoother pulling operation.

[0044] In a preferred embodiment of the present invention, in order to facilitate the hanging of the pull tab seat 1 onto the pull head body 3, the first connecting part 11 is a ring structure.

[0045] Example 2

[0046] Please see Figures 1 to 5As shown, this utility model discloses a zipper pull 200, which includes a zipper pull body 3 and a pull tab attached to the zipper pull body 3. The pull tab is a material point concealed pull tab 100. The specific structure and technical effects of the material point concealed pull tab 100 are exactly the same as those in Embodiment 1. Please refer to the detailed description of Embodiment 1 for details, which will not be repeated here. In practical applications, the zipper pull 200 of this utility model can be used on zippers used in clothing, bags, etc. Since the material inlet 21 on the injection molded part 2 is blocked by the concealing protrusion 13, the material inlet 21 is completely invisible from the appearance, which can greatly improve the overall appearance.
