Zipper puller with independent locking mechanism

Abstract

The invention provides a zipper puller with an independent locking mechanism. The zipper puller comprises a zipper puller body and a pull tab, the zipper puller body is provided with an upper wing plate and a lower wing plate, a sliding groove is formed in the small end of the upper wing plate, a sliding block is installed in the sliding groove through a limiting groove formed in the side wall of the sliding groove, and a through hole penetrating through the upper wing plate is formed in one end of the bottom of the sliding groove; a groove denting upwards is formed in the bottom face of the sliding block, an elastic piece is fixed in the groove, one end of the elastic piece is fixed to the sliding block, and the other end of the elastic piece stretches out of the bottom face of the sliding block in a natural state; when the sliding block slides to the through hole end of the sliding groove, and the free end of the elastic piece is located above the through hole, the free end of the elastic piece can penetrate through the through hole and abut against zipper teeth, and when the sliding block slides away from the through hole end, the elastic piece breaks out of the through hole and retracts into the groove of the sliding block. The zipper puller is provided with the independent locking mechanism and is simple in structure and low in manufacturing cost, the self-locking and unlocking functions of the zipper puller are reliable and stable, and the zipper puller is not prone to sliding down.

Description

technical field [0001] The invention relates to the technical field of slide fasteners, in particular to a slider with an independent locking mechanism. Background technique [0002] At present, the automatic sliders in the zipper industry all realize the pulling and self-locking of the zipper through the action of the pull piece and the hook. As disclosed in the Chinese invention patent CN200310114203. The elasticity of the shrapnel to unlock. However, this kind of hook interacts with the slider, and the structure is relatively complicated. Many sliders are stuck because the hook protrudes from the inner cavity of the slider. There are many problems when the protruding part of the inner cavity of the slider is too short or the slider is slipped due to improper treatment of painting and electroplating on the back. Contents of the invention [0003] In view of the above-mentioned problems in the prior art, the technical problem to be solved by the present invention is to ...
