Upper stopper assembly with freely-replaceable pull head

Abstract

The invention discloses an upper stopper assembly with a freely-replaceable pull head. The upper stopper assembly comprises a left upper stopper and a right upper stopper which are arranged on a left tooth chain belt and a right tooth chain belt respectively; the left upper stopper comprises an upper left upper stopper and a lower left upper stopper; the right upper stopper comprises an upper right upper stopper and a lower right upper stopper; the upper left upper stopper comprises an upper left limit portion, an upper left guide portion and an upper left clamp portion capable of elastically expanding or shrinking; the upper right upper stopper comprises an upper right limit portion, an upper right guide portion and an upper right clamp portion capable of elastically expanding or shrinking; when both of the upper left clamp portion and the upper right clamp portion elastically expand, the pull head is clamped on the left tooth chain belt and the right tooth chain belt in the upper left clamp portion and the upper right clamp portion; when both of the upper left clamp portion and the upper right clamp portion shrink, the pull head is capable of freely entering and exiting the upper left clamp portion and the upper right clamp portion. The upper stopper assembly with the structure is capable of realizing free replacement for the pull head, and meeting the needs of actual lives of people; the upper stopper assembly is finished by means of injection moulding or forming and then buckling-pressing in a die, thus improving the freedom degree during a zipper application process.

Description

technical field [0001] The invention relates to the field of zipper manufacturing, and more specifically refers to a top stop assembly with a freely replaceable slider. Background technique [0002] Zipper is a connecting piece that relies on continuous arrangement of chain teeth to make items merge or separate. It is widely used in clothing, bags, tents and other fabrics. In order to apply a zipper to fabrics, it generally includes a top stop assembly. The upper stop component is generally installed at the tail end of the tooth chain belt that the slider travels. moving parts. Because the slider of the general zipper is the sprocket of the buckle tooth chain belt from bottom to top, for this reason, the top stop component is generally located at the upper end of the clothes, which is why it is called the top stop. [0003] The traditional top stop assembly usually only includes a locking part capable of locking the slider, and the slider is limited by the locking par...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a top stop assembly that can freely replace the slider to solve the shortcomings of the existing top stop assembly that cannot be replaced, resulting in the waste of a large number of sliders or chain teeth.
