Pressing-type self-locking pull head

Abstract

The invention discloses a pressing-type self-locking pull head, which comprises a pull head main body, wherein the pull head main body is formed by integrally connecting a lower wing plate, a guide pillar and an upper wing plate; a connecting ring is arranged at the top of the upper wing plate; a self-locking hole is formed in the connecting ring; a pressing-type self-locking mechanism is arranged at the top of the connecting ring; the pressing-type self-locking mechanism is composed of a movable button, a reset spring and a fixed seat; an accommodating cavity is formed in the movable button; a self-locking ejector is arranged in the accommodating cavity; an accommodating groove is formed in the outer sidewall of the movable button, and an elastic clamping block is arranged in the accommodating groove; a mounting through hole is formed in the fixed seat; a first clamping groove, a second clamping groove and an elastic oscillating bar are arranged on the sidewall of the fixed seat; the bottom of the fixed seat is fixedly connected to the connecting ring; the movable button is arranged in the fixed seat; the reset spring is arranged in the accommodating cavity; the bottom of the self-locking ejector freely runs through the self-locking hole; and the bottom of the elastic clamping block is clamped in the first clamping groove. The pressing-type self-locking pull head provided by the invention is simple in structure, convenient to assemble and use and good in self-locking effect.

Description

technical field [0001] The invention relates to a slider, in particular to a push-type self-locking slider. Background technique [0002] At present, the self-locking function of the existing self-locking sliders on the market often relies on the horse hook and shrapnel installed on the slider body to realize the self-locking of the slider; the top of the horse hook is subjected to the pressure of the shrapnel, making the The free end of the horse hook catches the zipper teeth to realize the self-locking of the slider; the pull tab on the self-locking slider is pulled, and under the pulling force of the pull tab, the free end of the horse hook is separated from the zipper teeth to realize the unlocking of the slider. , the self-locking slider can be moved. After the movement is completed, the pull-tab is released, and the self-locking slider is restored to self-locking. This self-locking slider that relies on the cooperation of the horse hook and the shrapnel has the follow...

AI Technical Summary

Problems solved by technology

This kind of slider that relies on the mutual cooperation of the horse hook and the shrapnel to realize self-locking has the following defects: First, the existing self-locking slider has a relatively complicated structure, which makes the assembly process of the slider more cumbersome and complicated, which is not conducive to It is convenient and quick to assemble; secondly, during the use of the slider, there is a defect that the self-locking or unlocking action is not flexible enough, which may easily cause the slider to be stuck; in addition, the shrapnel and the hook are easily damaged during long-term use. Lead to poor self-locking of the slider or failure to lock itself, resulting in shortened life of the self-locking slider
