Abstract

A structure-improved riveting-free copper pull head comprises a pull head body, a elastic sheet and a pull sheet, wherein the pull head body comprises an upper wing plate, a lower wing plate and a guiding column, a convex block is arranged at the rear portion of the upper wing plate, and a protruding layer protruding out of the upper surface of the upper wing plate is arranged in the middle of theupper wing plate and is provided with an insertion hole. An insertion plate bent downwards is arranged in the middle of the elastic sheet, and a through hole is formed in the rear portion. The elastic sheet can be movably buckled and pressed on the pull head body, the insertion plate is inserted into the insertion hole to abut against the inner side wall of the protruding layer, and the convex block penetrates through the through hole to limit movement of the elastic sheet. The pull sheet can be clamped between the upper wing plate and the elastic sheet in a front-back rotatable way. When thepull sheet is turned and pulled forwards, the pull sheet abuts against the outer side wall of the protruding layer. By arranging the protruding layer, the pull sheet can directly abut against the outer side wall of the protruding layer without pressure exertion on the elastic sheet when rotating. Therefore, plastic deformation of the elastic sheet can be effectively prevented, and the service life of a zipper can be prolonged.

Description

technical field [0001] The invention relates to the field of slide fasteners, in particular to a riveting-free copper slider with improved structure. Background technique [0002] Most of the existing riveting-free copper sliders are composed of a slider body, a shrapnel and a pull piece. It has high requirements on the quality of the shrapnel. As long as the shrapnel is deformed, the entire copper slider will be declared damaged. Therefore, the copper slider design The most important thing is to avoid the deformation of the shrapnel during use, and the existing copper sliders are difficult to effectively solve this problem. [0003] Chinese invention patent for a zipper slider with a locking device (authorized notification number CN1165252C), which includes: a protruding piece arranged on the rear of the upper plate of the slider body and a pawl hole; A groove in the front surface of the guide post with an engaged portion: a leaf spring, which is in the shape of an inverte...
