Problems solved by technology

[0003] However, when the deadbolt of the existing lock is moved from the unlocked position to the locked position, the deadbolt will protrude a certain distance relative to the housing, so a deeper latch must be provided on the door frame relative to the deadbolt. slots for the lock tongue to protrude into it, but the door frame with a thinner thickness often cannot be equipped with a deeper locking groove, or the locking groove of the existing door frame needs to be dug deeper to match the movement of the lock tongue, so There are many restrictions and inconveniences in use

Embodiment Construction

[0044] Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

[0045] The present invention is mainly about a kind of lockset, please refer to Figure 1 to Figure 3 , as can be seen from the figure, the lockset of the present invention mainly includes a housing 10, a dead bolt 20, a dead bolt seat 22, a linkage 30, a locking mechanism 60 and a linkage mechanism 50, the shell The body 10 is used to be installed on a door panel, and an accommodating space is formed in the housing 10, which can be composed of a base and a cover. One end of the tongue 20 can protrude from the casing 10 , and the bolt seat 22 is fixedly connected to the bolt 20 and can move relative to the casing 10 .

[0046] The linkage 30 is movably arranged in the casing 10, and is connected with the bolt seat 22, and forms a relative displacement with the bolt seat 22, and is located between the linkage 30 and the bolt s...

Abstract

The invention discloses a lock, which comprises a housing, a deadbolt, a deadbolt seat, a linkage and a locking mechanism. The deadbolt is telescopically and movably arranged in the housing, and can protrude from the housing. Outside the body, the deadbolt seat is fixedly connected with the deadbolt seat, and can move relative to the housing. The linkage member is movably arranged in the housing, and is connected with the deadbolt seat, and forms a relative displacement with the deadbolt seat. Wherein, one of the linking piece and the deadbolt seat is provided with a moving groove that allows the linking piece to move relative to the deadbolt seat, and the locking mechanism is arranged on the housing and can abut against the linking piece, so that The deadbolt seat and the deadbolt are positioned at the locking position, thereby constituting a lockset applicable to different door frame thicknesses.

Description

technical field [0001] The invention relates to a lock, in particular to a lock applicable to door frames of different thicknesses. Background technique [0002] Existing locks, such as German Patent No. 20212010386 or German Patent No. 19839043, etc., are mainly provided with a dead bolt that can be telescopically moved relative to the housing in a housing, and a lock that is linked with a handle is provided in the housing. The handle interlock mechanism, and a lock bolt interlock mechanism that can be driven by a lock core structure to drive the dead bolt relative to the housing between a locked position and an unlocked position is provided in the housing. The handle can still rotate freely when the lock tongue is in the locked position. When the lock tongue is in the locked position, the lock tongue linkage mechanism and the handle linkage mechanism are in a state of disengagement from each other. Therefore, when the lock tongue is in the lock position, they will be oppos...
