Abstract

The invention relates to the technical field of door locks, and discloses a spring bolt assembly of a door lock. The spring bolt assembly of the door lock comprises a shell, a first driving part, a stroke amplification mechanism, a spring bolt and a connecting assembly, wherein the first driving part is rotatably arranged in the shell; the stroke amplification mechanism comprises a mounting frame and a second driving part; the mounting frame is arranged in the shell; the first driving part can drive the mounting frame to slide; the second driving part is rotatably arranged in the shell, and abuts against the mounting frame; the spring bolt is arranged on the shell in a telescopic mode; and the connecting assembly is movably arranged in the shell, and is connected with the second driving part and the spring bolt. The spring bolt assembly of the door lock provided by the invention has the advantages that all the components are installed in the shell, and the overall lock shell design is adopted, so that the strength of the spring bolt assembly is enhanced, and the service life is prolonged; the stroke amplifying mechanism is arranged, so that a door can be opened only by rotating a door handle by a small angle, and use is convenient; and the spring bolt can be reversed, so that the spring bolt assembly can be applied to an inward opening door or an outward opening door, and is high in universality.

Description

technical field [0001] The invention relates to the technical field of door locks, in particular to a deadbolt assembly of a door lock. Background technique [0002] As an important medium for the entrance and exit of building rooms and ventilation and lighting, doors usually need to be equipped with door locks to ensure the sealing of rooms or passages; among them, the deadbolt assembly is an important part of the door lock, the stability and use of the deadbolt assembly Convenience is especially important. [0003] Existing door locks usually drive the telescopic movement of the deadbolt by turning the door handle, and the door handle needs to be turned at a relatively large angle to realize the retraction of the dead bolt to open the door. , affecting unlocking and reducing the service life of the door lock. Contents of the invention [0004] Aiming at the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is to ...
