Down pants zipper puller riveting mechanism

Abstract

The invention belongs to the technical field of zipper manufacturing, and particularly relates to a down pants zipper puller riveting mechanism. The mechanism comprises a puller body, a pull piece and an elastic piece, the puller body is riveted with the pull piece through a riveting nose, and an elastic piece groove and a self-locking groove which are matched with the elastic piece for locking are sequentially formed in the upper end face of the puller body. The self-locking groove is located below the riveting nose, and a springback self-locking mechanism is arranged in the riveting end of the pull piece and the self-locking groove. The riveting nose and the pull piece are arranged on the puller body, and the springback self-locking mechanism is arranged at the bottom of the rivet pressing position, so that self-locking of the puller and resetting of the elastic piece in the pull-up process of the pull piece can be realized, and the situation that the pull piece cannot fall and reset under the gravity action of the pull piece is avoided; the restoring force after the puller is unlocked is increased by ingeniously arranging the torsional spring, so the self-locking performance of the zipper puller is improved; and the zipper puller is simple in inner structure, ingenious in design, convenient to use and convenient to popularize and use in the down pants zipper puller industry.

Description

technical field [0001] The invention belongs to the technical field of zipper manufacturing, and in particular relates to a riveting mechanism for a zipper head of down trousers. Background technique [0002] In the cold winter, people wear down clothing, and down trousers are relatively bloated due to their bulkiness, so down trousers zippers often use zipper pullers with self-locking structures; Self-locking sliders, zippers are basically composed of sliders, cloth belts, chain teeth, square pins, etc. The sliders not only affect the functional role of the zipper opening and closing, but also affect the appearance and convenience of use. Therefore, the slider's Structural design is critical. [0003] However, the sliders in the prior art usually have the phenomenon that the pull tab is stuck, that is, in the process of long-term use, the pull tab is lifted and stuck, and cannot be dropped and reset by its own gravity after the external force is removed. , causing the zip...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a zipper puller for down pants with simple structure and reasonable design in order to solve the above-mentioned problems that the pull tab is prone to jacking up and the pull tab is difficult to reset after jacking up, which leads to the lock of the slider. riveting mechanism
