Description

Quick-release fastener

Technical Field

The present utility model relates to a quick release fastener, and more particularly, to a fastener in which a sub-fastener can be easily inserted into a female fastener to achieve fastening, and a pull string is pulled to quickly unlock, which can be used on an article of clothing that needs to be quickly and easily removed by a wearer.

Background

The safety buckle generally comprises a female buckle and a male buckle, wherein the male buckle is provided with a lock tongue, the female buckle is provided with a lock hole, and the lock tongue is inserted into the lock hole to enable the male buckle and the female buckle to be locked and connected together. The sub-buckle and the main buckle can be separated from each other by operating the unlocking.

In general, the locking hole of the female buckle is generally composed of a fixing hole and a locking part with changeable position. When the locking part stretches out of the fixing hole, the locking part can play a role of locking, and the lock tongue is locked in the lock hole, so that the sub-buckle and the female buckle are in locking connection. When the locking part withdraws from the fixing hole, the lock tongue can freely enter and exit from the fixing hole and withdraw from the lock hole, so that the sub-buckle and the female buckle can be separated. The quick release buckle is used as a safety buckle and is mainly used for releasing special clothes or articles in emergency.

A quick release buckle system is described in U.S. publication No. US2010313327 A1. In this buckle, the cable system is directly attached to the locking leg of the male portion of the buckle, such that pulling the cable pulls the leg inwardly. Because the leg of the child buckle needs to ensure the connection strength of the female buckle and the child buckle after being buckled, the leg of the child buckle needs to be designed with higher flexibility, so that a great force is required to pull the leg to separate the child buckle from the female buckle inwards, which is contrary to the aim that a wearer can easily remove the vest in emergency.
