Lock with bolt adjusting mechanism

Abstract

A lock with a bolt adjusting mechanism comprises a lock shell and a first bolt. The bolt adjusting mechanism comprises a stirring part and a slider, a rotating pivot is arranged on the stirring part, the slider is arranged at the tail end of the first bolt and can move in the horizontal direction, and the stirring part and the slider are arranged up and down. A first joint point and a second joint point are further arranged on the stirring part, and the distance between the second joint point and the rotating pivot is larger than that between the first joint point and the rotating pivot. When the slider moves to the position corresponding to the first joint point, the slider leaves the position of the second joint position, and the stirring part is jointed with the slider at the first joint point to form first drive fit; when the slider moves to the position corresponding to the second joint point, the slider already leaves the position of the first joint point, and the stirring part is jointed with the slider at the second joint point to form second drive fit. Therefore, the length of the bolt can be flexibly set according to gap sizes of different door crack gaps or according to the size of antitheft strength needing to be provided.

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
