Novel snap fastener

Abstract

The invention discloses a novel snap fastener. The snap fastener comprises a male fastener assembly and a female fastener assembly which are provided with a first assembly and a second assembly respectively; the first assembly comprises a first fastener shell, fastener clamps and a fastener sheet; the fastener clamps are fixedly assembled on the first fastener shell and provided with clamping holes; the fastener sheet is arranged between the first fastener shell and the fastener clamp, an annular groove is formed in the side surface, facing the clamping holes, of the fastener sheet, and the cross section of the inner groove wall of the annular groove is arc; the second assembly comprises a second fastener shell and fastener pins, and the fastener pins are fixedly assembled on the second fastener shell and provided with fastener pin parts extending outwards into the clamping holes; the second fastener shell of the second assembly of the male fastener assembly forms a fastener bead part;a concave fastener groove part is formed in the first fastener shell of the first assembly of the female fastener assembly, or a concave fastener groove part is formed in the second fastener shell ofthe second assembly of the female fastener assembly. The novel snap fastener achieves the effect of fastening the assemblies stably and firmly by means of the ingenious structure of the fastener sheet.

Description

[0001] This application is aimed at "a new type of buckle" with the application number "201510511642.2" and the application date "2015.8.20". Components and four-in-one buckle” filed a divisional application. technical field [0002] The invention relates to the field of buttons, in particular to a novel four-joint button. Background technique [0003] The four-button button is a commonly used connecting tool for connecting two skirts together, and it mainly plays the role of fastening connection. Usually, the four-way buckle is divided into four parts from top to bottom: the buckle surface, the buckle shell, the buckle bead, and the buckle foot. The buckle surface and the buckle shell are combined to form a female buckle assembly. There are two parallel springs; the buckle and the buckle foot are combined to form a male buckle assembly, and a buckle protrudes from the middle of the male buckle, and the buckle is pressed into the buckle groove of the female buckle and the...

AI Technical Summary

Problems solved by technology

[0004] At present, in the structural design of the four-button buckle, only the connection performance between the male buckle and the female buckle is considered emphatically, and the connection performance between the two parts of the female buckle and the male buckle has not been studied too much, and then in practice In the process, it often happens that the two parts of the female button or the male button are not stable and firm enough to cause the button to be damaged.
