Abstract

The invention relates to a self-locking plastic puller, which includes a puller body, a pulling piece, hooks, elastic pieces and a cover cap. The puller body is composed of an upper wing plate, a guide post and a lower wing plate, a front boss and a rear boss are arranged on the front part and the rear part of the top face of the upper wing plate correspondingly, a pivot shaft of the pulling piece is arranged between the front boss and the rear boss, the front boss and the rear boss are provided with installation grooves for assembling the hooks correspondingly, the cover cap and the elastic pieces are formed by integrated injection molding of elastic materials, the front and rear ends of the cover cap are buckled on the front boss and the rear boss correspondingly, and the elastic pieces are top-supported on the hooks. According to the puller, the cover cap and the elastic pieces are formed by integrated injection molding, the structure is simple, the cost is low, the puller can be quickly and conveniently assembled, and the reject ratio of finished products is low.

Description

technical field [0001] The invention relates to the technical field of zipper sliders, in particular to a self-locking plastic slider. Background technique [0002] The existing self-locking sliders are usually composed of a slider body, a pull piece, a hook, a shrapnel, and a cap. The shrapnel is usually fixed and embedded in the cap by a snap-in method, but because the shrapnel is small, the thickness is only 0.11mm, and The structure of the cap is relatively complicated. In the production process, it is not only difficult to assemble the shrapnel into the cap, but also the assembly efficiency is slow, the assembly process is cumbersome, and the scrap rate of the finished product after assembly is high. In addition, most of the shrapnel on the market are made of stainless steel, and its processing and cost are relatively high. Contents of the invention [0003] The invention provides a self-locking plastic slider to solve the existing problems of difficult assembly of s...
