By installing the connecting component 2, when the zipper enters the interior of the slider body 1, the slider body 1 contacts the zipper chain teeth through the roller 22, which reduces the contact area between the chain chain teeth and the slider body 1, and realizes rolling friction, thereby reducing the friction between the zipper chain teeth and the slider, and improving the smoothness of the pulling feeling. Under the action of the spring 23, the roller 22 and the support frame 21 still have a certain amount of activity space, thereby further improving the smoothness of the pulling feeling.
[0030] like Figure 1 to Figure 2 As shown, a slider 3 is installed on the support frame 21, and a limiting groove 31 is provided on the hole wall of the mounting through hole 25, and the slider 3 is slidably installed in the limiting groove 31; the slider 3 on the support frame 21 moves along the length direction of the limiting groove 31, thereby limiting the movement of the support frame 21, and further enabling the support frame 21 to move within a limited space and position.
[0031] like Figure 1 to Figure 2 As shown, a plurality of support frames 21 and a plurality of rollers 22 are evenly installed inside the mounting seat 24, and the plurality of rollers 22 correspond to the plurality of support frames 21 one by one, and the rollers 22 are rotatably installed on the support frames 21, and springs 23 are installed on the tops of the plurality of support frames 21, and one end of the spring 23 away from the support frame 21 is connected to the inner wall of the mounting seat 24; the direct contact between the zipper chain teeth and the slider body 1 can be reduced, and the friction between the zipper chain teeth and the slider body 1 is rolling friction, thereby improving the smoothness of pulling.
[0032] like Figure 1 to Figure 2 As shown, the mounting seat 24 is installed on the slider body 1 along the direction of movement of the zipper; the rotation direction of the roller 22 is consistent with the direction of movement of the zipper, so that there is rolling friction between the roller 22 and the zipper teeth, reducing friction and improving smoothness.
[0033] like Figure 1 to Figure 2As shown, a connection component 2 for sliding contact with the zipper is installed on the top plate 11 and the bottom plate 12 of the slider body 1; the zipper teeth are indirectly connected to the top plate 11 and the bottom plate 12 of the slider body 1 through rollers 22, so that the zipper teeth move between the two rollers 22, and the top and bottom of the zipper teeth are in rolling friction with the rollers 22, thereby improving the smoothness.
[0034] like Figure 1 to Figure 2 As shown, arc-shaped guide blocks 32 are installed at both ends of the mounting seat 24; the mounting seat 24 contacts the clothing fabric around the zipper through the arc-shaped guide blocks 32, thereby avoiding interference of the clothing around the zipper with the movement of the slider body 1 to a certain extent, thereby improving smoothness.
[0035] like Figure 1 to Figure 2 As shown, guide plates 33 are installed at both ends of the bottom plate 12 of the slider body 1. The side of the guide plate 33 facing the top plate 11 of the slider body 1 is an inclined surface, and the end of the guide plate 33 away from the slider body 1 is rounded; when the zipper head is closed and separated, there is a transition guide space for the teeth to enter or come out of the zipper head, which makes the closing and separation of the zipper more labor-saving and more convenient to operate.
[0036] like Figure 1 to Figure 2 As shown, a guide column 34 is installed at the position of the connecting column 13 on the slider body 1. The surface where the guide column 34 connects with the zipper is an arc surface. The guide column 34 can divert the teeth on both sides when the zipper head is separated from the teeth, thereby improving the sliding effect.
[0037] The implementation principle of this embodiment is: when the zipper enters the interior of the slider body 1, the slider body 1 contacts the zipper teeth through the roller 22, reducing the contact area between the chain teeth and the slider body 1, and realizing rolling friction, thereby reducing the friction between the zipper teeth and the slider and improving the smoothness of the pulling feeling.
