Locks with improved structure

Abstract

A lock with an improved structure comprises a lock tongue buckling cover and a lock body. The lock body is provided with a lock tongue, and the lock tongue buckling cover comprises a surface shell and an inner shell. The lug portions at the upper end and the lower end of the surface shell and the lug portions at the upper end and the lower end of the inner shell are respectively provided with a locating hole, and the locating holes of the inner shell are in a long slot shape which extends in the left-right direction. The inner shell is provided with a recessed cavity, a first protruding edge which extends in the up-down direction is arranged on one side of the recessed cavity, and the inner side face of the first protruding edge is a slope face. A first magnetic attraction block is arranged at the bottom of the inner side of the recessed cavity of the inner shell, and a second magnetic attraction block is arranged on the lock tongue. A long slotted hole which extends in the stretching direction of the lock tongue is formed in a lock shell, a protruding block which is matched with the long slotted hole is fixedly arranged on the rod portion of the lock tongue, and the protruding block extends into the long slotted hole and can slide in the long slotted hole. By means of the lock with the improved structure, door closing noise can be reliably reduced, door leaf vibrating noise can also be avoided, and therefore the lock can be applied to cylinder inserting lock products such as a room door lock used indoors.

Description

technical field [0001] The invention relates to a lockset, especially a mortise lockset suitable for being arranged between a door leaf and a door frame. The biggest feature of the mortise lockset is that it has a retractable deadbolt, and the deadbolt can be inserted into a deadbolt buckle box installed on the door frame. Background technique [0002] For mortise door locks, the width of the cavity of the deadbolt box in the direction of opening and closing the door will be much larger than the thickness of the deadbolt. The result is that when the deadbolt is inserted into the deadbolt box, the door leaf will When moving, it will shake back and forth so as to drive the dead bolt to swing and make noise in the described dead bolt buckle box. For indoor door lock products, this shaking sound is noise, which seriously affects people's rest. For how to overcome or reduce the noise problem generated during the use of the door lock, there are already many solutions such as add...

AI Technical Summary

Problems solved by technology

For how to overcome or reduce the noise problem generated during the use of the door lock, there are already many solutions such as adding a plastic sleeve to the outer side of the lock tongue, etc., but these solutions are mainly aimed at the noise problem that occurs during the opening process of the door lock , can not solve the noise problem that the door lock still exists after opening
