Lock with tongue adjustment mechanism

Abstract

A lockset with a deadbolt adjustment mechanism, comprising a lock housing and a first deadbolt; the deadbolt adjustment mechanism includes a toggle piece and a sliding block; the toggle piece has a rotation axis point; the sliding block is arranged at the end of the first deadbolt The end part can move in the horizontal direction, and the toggle piece and the sliding block are arranged up and down; the toggle piece also has first and second joint points, and the distance between the second joint point and the rotation axis point is greater than the first joint point The distance from the rotation axis point; when the sliding block moves to the position corresponding to the first joint point, the sliding block has left the position of the second joint point, and the toggle piece combines with the sliding block at the first joint point to form the first type Driving fit; when the sliding block moves to the position corresponding to the second joint point, the sliding block has left the position of the first joint point, and the toggle member combines with the sliding block at the second joint point to form the second driving fit. For this reason, the length of the deadbolt can be flexibly set according to the size of the different door gaps or the size of the anti-theft strength provided as required.

Description

technical field [0001] The present invention relates to a lockset for locking doors, windows and other appliances, in particular to a lockset with a bolt adjusting mechanism. The deadbolt of the lockset can have two protruding lengths, so that the required length of the deadbolt can be flexibly set according to the size of different door gaps or the anti-theft strength required. Background technique [0002] The lockset in the prior art has a retractable deadbolt so that the door leaf and the door frame can be locked by means of the deadbolt so as to realize the locking function of locking. However, with regard to these locksets, no matter whether it is through one-stage unscrewing or multi-stage unscrewing of the deadbolt, the maximum length of the deadbolt of a lockset is a fixed length, so that it is suitable for doors of different door gap sizes or needs The anti-theft strength of different sizes is very passive, either the length of the deadbolt is not enough or the de...

Problems solved by technology

However, with regard to these locksets, no matter whether it is through one-stage unscrewing or multi-stage unscrewing of the deadbolt, the maximum length of the deadbolt of a lockset is a fixed length, so that it is suitable for doors of different door gap sizes or needs The anti-theft strength of different sizes is very passive, either the lock tongue is not long enough or the lock tongue is too long, which is a distressing thing for the manufacturer or the sales and installation personnel
