DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following further describes the present utility model with reference to the accompanying drawings, but the protection scope of the present utility model is not limited to the following.

[0031] Such as Figures 1 to 4As shown in the figure, an inner-arc zipper slider includes a slider body 1, a nose 11 and a tab 12. The nose 11 is installed on the top of the slider body 1, and the tab 12 is sleeved on the nose 11 and is slidably connected to the nose 11. An arc-shaped avoidance groove 2 is formed on the top plate of the slider body 1 and at the bottom of the nose 11. An installation groove 3 is formed along the length direction of the nose 11, and a protective strip 31 is installed in the installation groove 3. The setting of the avoidance groove 2 can increase the space between the nose 11 and the slider body 1, thereby improving the smoothness of the rotation of the tab 12 between the nose 11 and the slider body 1, and to a certain extent preventing the tab 12 from getting stuck when rotating between the nose 11 and the slider body 1, scratching the surface of the slider body 1 or causing the paint on the surface of the slider body 1 to fall off. Moreover, by providing the protective strip 31 on the nose 11, the tab 12 indirectly contacts the nose 11 through the protective strip 31, reducing the friction between the tab 12 and the nose 11, and thus playing a certain protective role for the tab 12 and the nose 11. In addition, by providing the avoidance groove 2, the weight of the slider body 1 can be reduced, to a certain extent reducing the amount of materials used for making the slider body 1 and reducing the alloy cost.

[0032] As Figures 1 to 4 shown, a tail block 13 is installed at the tail of the top plate of the slider body 1, and a flexible pad 21 is installed on the tail block 13. When the tab 12 is placed horizontally or vertically, the tab 12 will first contact the flexible pad 21, and there will be a suspension between the position where the end of the tab 12 contacts the nose 11 and the position where the tab 12 contacts the flexible pad 21, thereby avoiding the wear of the surface of the slider body 1 by the tab 12 and protecting the paint on the surface of the slider body 1.

[0033] As Figures 1 to 4 shown, a plurality of abutting columns 15 are evenly installed at the head position of the top plate of the slider body 1. Installation holes 16 for installing the abutting columns 15 are formed on the top plate of the slider body 1. The plurality of abutting columns 15 respectively contact the surface of the tab 12. When the tab 12 is located at the head position of the slider body 1, the tab 12 contacts the slider body 1 through the abutting columns 15, so that there is a certain gap between the tab 12 and the slider body 1, thereby playing a certain protective role for the surface of the slider body 1.

[0034] As Figures 1 to 4As shown in the figure, a plurality of mounting posts 32 are uniformly installed on the protective strip 31 along its length direction. A limiting block 33 is installed at one end of the mounting post 32 away from the protective strip 31. A connecting hole 34 for placing the mounting post 32 is opened on the bottom wall of the mounting groove 3. The cross-sectional shape of the connecting hole 34 is T-shaped. The radius length of the limiting block 33 is greater than the radius length of the mounting post 32. When installing the protective strip 31, the staff aligns the mounting post 32 with the connecting block, and then presses the protective strip 31 so that the mounting post 32 and the limiting block 33 enter the connecting hole 34. The limiting block 33 is first compressed. When the limiting block 33 is located at the bottom of the connecting hole 34, it will return to its original shape, thus playing a fixing role for the protective strip 31. The protective strip 31 is detachably installed in the mounting groove 3 through the mounting post 32 and the limiting block 33, which is convenient for later replacement.

[0035] As Figures 1 to 4 shown in the figure, a semi-circular flexible strip 35 is provided on one side of the protective strip 31 away from the avoidance groove 2. The pull tab 12 will be tangent to the semi-circular flexible strip 35, thereby reducing the contact area between the pull tab 12 and the flexible strip 35, reducing the wear on the surface of the pull tab 12, and playing a certain protective role for the pull tab 12.

[0036] As Figures 1 to 4 shown in the figure, a flexible ball 17 is installed on the top of the abutting post 15. The flexible ball 17 is tangent to the surface of the pull tab 12, thus being a point contact. Compared with the surface contact between the pull tab 12 and the pull head body 1 directly, it can reduce the contact area and play a certain protective role for the paint layer on the surface of the pull tab 12.

[0037] As Figures 1 to 4 shown in the figure, a flexible pad 21 is installed in the avoidance groove 2. It reduces the wear of the pull tab 12 on the groove wall of the avoidance groove 2 during rotation, making the pull head body 1 more beautiful.

[0038] As Figures 1 to 4 shown in the figure, a flexible sleeve 18 is sleeved on the pull tab 12. It plays a certain protective role for the surface of the pull tab 12, reduces wear, and makes the overall zipper head more beautiful.

[0039] The implementation principle of this embodiment is as follows: The setting of the avoidance groove 2 can increase the space between the pull nose 11 and the pull head body 1, thereby improving the smoothness of the rotation of the pull tab 12 between the pull nose 11 and the pull head body 1, preventing the pull tab 12 from getting stuck when rotating between the pull nose 11 and the pull head body 1 to a certain extent, and preventing the surface of the pull head body 1 from being scratched or the paint on the surface of the pull head body 1 from falling off. And by setting the protective strip 31 on the pull nose 11, the pull tab 12 indirectly contacts the pull nose 11 through the protective strip 31, reducing the friction between the pull tab 12 and the pull nose 11, and thus playing a certain protective role for the pull tab 12 and the pull nose 11.

[0040] The above are only the preferred embodiments of the present utility model and do not impose any formal restrictions on the present utility model. Any person skilled in the art can, without departing from the scope of the technical solution of the present utility model, make many possible changes and modifications to the technical solution of the present utility model by using the above-mentioned technical content, or modify it into an equivalent embodiment with equivalent changes.
