Abstract

The invention discloses a self-locking zipper head, which comprises a slide block body and a pull head trunk. The pull head trunk comprises a positioning part and a connecting part and is fixed on the slide block body through the connecting part. The self-locking zipper head also comprises a hook and an elastic sheet; a through hole is formed at a hooking part of the hook corresponding to an upper wing plate of the slide block body; the elastic sheet is used for elastically pressing the hook; two connecting columns are arranged on the upper wing plate of the slide block body; two ends of the elastic sheet are arranged on the connecting columns respectively; two limited blocks are arranged at two ends of the elastic sheet corresponding to the connecting part of the pull head trunk; the limited blocks are positioned above the two ends of the elastic sheet; the connecting columns and the two ends of the elastic sheet corresponding to the limiting blocks are provided with guiding structures; and the guiding structures make the two ends of the elastic sheet reciprocate between the connecting columns and the limited blocks. The self-locking zipper head has the advantage of convenience of manufacture.

Description

technical field [0001] The invention relates to a zipper puller, in particular to a self-locking zipper puller provided with a slider elephant trunk. Background technique [0002] Existing zipper sliders can be roughly divided into self-locking zipper sliders and non-self-locking zipper sliders. The self-locking zipper head can prevent sliding under non-artificial conditions through a specially set self-locking mechanism, while the non-self-locking zipper head may slide along the zipper tape under non-artificial conditions. For example, Chinese Utility Model Patent No. 200720048784.0 published on February 27, 2008 discloses a slider for a slider, which includes a slider base and a slider trunk. Two hook ears are formed on the front end of the upper surface of the slider base, and two tail fins are provided on the rear end of the upper surface of the slider base.
