The invention relates to a double-pulling type self-locking zipper head. The double-pulling type self-locking zipper head comprises a pull head body, two caps, two zipper pulls and an elastic component. The pull head body comprises an upper wing plate, a lower wing plate and a connecting pole, the lower wing plate is provided with a through hole, the connecting pole, the upper wing plate and the lower wing plate are integrally formed, the connecting pole is internally provided with a connecting channel, the lower wing plate is provided with a brake component which comprises a drive part, a pivoting part and a hook part, the drive part extends into the connecting channel, the pivoting part is pivoted to the lower wing plate through a first pin, the upper wing plate is provided with a linkage part and a sliding part, the linkage part is pivoted to the upper wing plate through a second pin, the linkage part extends into the connecting channel to abut against the brake component, the sliding part is connected with the linkage part and the brake component, the two zipper pulls are connected with the sliding part and the brake component respectively, the elastic component elastically abuts against and presses the brake component, and the hook part of the brake component extends outside the lower wing plate. According to the double-pulling type self-locking zipper head, any zipper pull has the function of removing braking, the structure is compact, drive is stable, assembly is easy, and operation is easy and convenient.
Description
technical field [0001] The invention relates to the technical field of zipper sliders, in particular to a double-pull self-locking zipper slider. Background technique [0002] The existing double-pull zipper pulls can be roughly divided into self-locking double-pull zipper pulls and non-self-locking double-pull zipper pulls. Non-self-locking double-pull zipper pulls may occur Sliding, while the self-locking double-pull zipper head can prevent sliding under non-human operating conditions through a specially set self-locking mechanism. For example, the Chinese invention patent with the application publication number CN102406289 A discloses a double-sided self-locking zipper puller, including a slider body, two caps, upper hooks, lower hooks and elastic elements. The slider includes upper wings, The connecting column and the lower wing plate, the upper wing plate and the lower wing plate are provided with through holes, and the connecting column is provided with a connecting c...
