Problems solved by technology

[0003] The traditional self-locking slider, because there is only one shrapnel and a hook inside the self-locking slider, so after a period of use, once the shrapnel or the hook is damaged, it is prone to poor self-locking or self-locking failure, and self-locking occurs. The slider automatically slides down on the zipper or the self-locking is not up to standard, and the self-locking function is poor; in addition, it will also shorten the service life of the self-locking zipper head

Embodiment 1

[0023] Such as Figure 1 to Figure 7 As shown, a self-locking slider with double horse hooks includes a slider body 1, a pull piece 2, a cap 3, a shrapnel 4 and two horse hooks 5. The slider body 1 is composed of a lower wing plate 11, a guide post 12 is connected with the upper wing plate 13, the front end of the top surface of the upper wing plate 13 is provided with a front mounting part 14, the top rear end of the upper wing plate 13 is provided with a rear mounting part 15, and the pivot 21 of the pull piece 2 is arranged on the front Between the mounting part 14 and the rear mounting part 15, the cap 3, the shrapnel 4 and two horse hooks 5 are mounted on the front mounting part 14 and the rear mounting part 15, so that the shrapnel 4 presses the tops of the two horse hooks 5.

[0024] Such as Figure 1 to Figure 3 As shown, the front mounting part 14 is provided with two first mounting holes 141 for assembling the horse hook 5 in parallel, a first partition 144 is arran...

Embodiment 2

[0030] Such as Figure 8 and Figure 9As shown, on the basis of Embodiment 1, the groove positioning structure on the top of the front mounting part 14 and the rear mounting part 15 of the slider body 1 is set as an upwardly protruding positioning structure, specifically: in the front mounting part The top of 14 is provided with first positioning projection 146, and the top of rear mounting part 15 is provided with second positioning projection 156, and the structure of first positioning projection 146 and second positioning projection 156 are identical, and both are square projections. block; and the inside of the cap 3 does not need to be provided with a positioning structure corresponding to the first positioning protrusion 146 and the second positioning protrusion 156 . The assembly process of the self-locking slider in Example 2 is basically the same as that of the self-locking slider in Example 1, the only difference is that in Example 1, the shrapnel 4 is first assembl...

Abstract

The invention provides a self-locking puller with double horse hooks. The self-locking puller comprises a puller body, a pulling sheet, a cap, an elastic sheet, and two horse hooks, the puller body is constituted by making a lower wing plate, a guide pillar and an upper wing plate connected, a front installation part and a rear installation part are arranged at the top surface of the upper wing plate, two first installation holes are formed in the front installation part, and two second installation holes are formed in the rear installation part; first connecting clamping grooves are formed in both the left side wall and the right side wall of the front mounting part, and second connecting clamping grooves are formed in both the left side wall and the right side wall of the rear mounting part; a first positioning groove is formed in the top of the front installation part, and a second positioning groove is formed in the top of the rear installation part; an opening groove is formed in the middle of the elastic sheet, and the elastic sheet is separated into a left elastic sheet and a right elastic sheet, and the left elastic sheet and the right elastic sheet are symmetrically arranged; loading lugs are arranged at the top end of the inside of the cap. In the elastic sheet of the self-locking puller, two mutually independent elastic parts are arranged to correspond to the two horse hooks, when the left elastic sheet and the right elastic sheet apply acting force to the corresponding horse hooks to achieve self-locking of the puller, the left elastic sheet and the right elastic sheet are not interfered mutually, and thus the self-locking function of the puller is sharply promoted.

Description

technical field [0001] The invention relates to a slide fastener head, in particular to a self-locking pull head with double horse hooks. Background technique [0002] At present, the traditional self-locking sliders on the market are often equipped with a shrapnel and a horse hook inside the self-locking slider, and its self-locking function is often realized by the horse hook and shrapnel installed on the slider body. Self-locking; the top of the hook is under the pressure of the shrapnel, so that the free end of the hook is stuck on the zipper element, and the slider is self-locking; the pull piece on the self-locking slider is pulled, and under the pulling force of the pull piece , the free end of the horse hook is separated from the zipper teeth, the slider is unlocked, and the self-locking slider can be moved. After the movement is completed, the pull tab is released, and the self-locking slider resumes self-locking. [0003] The traditional self-locking slider, becau...
