Detailed Description

The following describes specific embodiments of the present invention with reference to the drawings.

Referring to fig. 1 to 5, a self-locking plastic slider comprises a slider body 1, a pull tab 2, a horse hook 3, an elastic sheet 41 and a cover cap 4, wherein the slider body 1 is composed of an upper wing plate 11, a guide pillar 12 and a lower wing plate 13, a front boss 14 and a rear boss 15 are respectively arranged at the front and the rear of the top surface of the upper wing plate 11, a pivot 21 of the pull tab 2 is arranged between the front boss 14 and the rear boss 15, mounting grooves 16 used for assembling the horse hook 3 are respectively formed in the front boss 14 and the rear boss 15, and inner steps 17 respectively used for supporting a head 31 and a tail 32 of the horse hook 3 are respectively arranged in the two mounting grooves 16.

Referring to fig. 3 and 4, the cap 4 and the elastic piece 41 are integrally formed by injection molding of an elastic material, and in the present embodiment, the cap 4 and the elastic piece 41 are preferably integrally formed by injection molding of a plastic material. The front end and the rear end of the cover cap 4 are respectively buckled on the front boss 14 and the rear boss 15, and the elastic sheet 41 is supported on the horse hook 3. More specifically, in this embodiment, the elastic sheet 41 extends downward from the inner side wall of the top of the cap 4, the elastic sheet 41 is in a vertical sheet shape, and the elastic sheet 41 is bent and then supported on the hook 3. The front end and the rear end of the cap 4 are both provided with a clamping block 42 in an inward protruding manner, and the assembly bayonets 18 matched with the corresponding clamping blocks 42 on the cap 4 are arranged at the front end of the front boss 14 and the rear end of the rear boss 15 of the slider body 1.

Referring to fig. 1 to 5, when the slider is assembled, the slider body 1 is firstly placed horizontally, and then the pivot 21 of the pull piece 2 is placed horizontally between the front boss 14 and the rear boss 15 of the slider body 1; then the horse hook 3 is placed on the pulling piece 2, two ends of the horse hook 3 are respectively placed in the mounting grooves 16 of the front boss 14 and the rear boss 15, and the head and the tail of the horse hook 3 are respectively placed on the inner steps 17 of the front mounting groove 16 and the rear mounting groove 16; after the horse hook 3 is installed, the integrated cap 4 with the elastic sheet 41 is buckled on the front boss 14 and the rear boss 15. Before assembling the cap 4, the elastic sheet 41 on the cap 4 is bent to the horizontal direction along the counterclockwise direction from the vertical direction, so that the elastic sheet 41 obtains a certain compression elastic force, then the clamping blocks at the front end and the rear end of the cap 4 are respectively clamped into the assembling bayonets of the front boss 14 and the rear boss 15, and after the assembling is completed, the bent elastic sheet 41 presses the clevis 3, thereby realizing the self-locking function of the pull head. When the zipper puller is used, the zipper puller 2 is lifted, the horse hook 3 is lifted by the zipper puller 2, self-locking is released, and the opening and closing functions of the zipper puller are realized; and (4) loosening the pull piece 2, and enabling the horse hook 3 to return to a self-locking state under the pressure action of the elastic sheet 41 to finish the self-locking of the pull head.
