Improved automobile door lock

Abstract

The utility model relates to the technical field of automobiles, in particular to an improved automobile door lock which comprises a connecting plate and a mounting hole, the mounting hole is formed in the surface of the connecting plate, a connecting mechanism is arranged on the outer wall of the connecting plate and comprises a first connecting column, and the outer wall of the connecting column is connected with the connecting plate. The outer wall of the first connecting column is in threaded connection with a mounting plate, and the surface of the mounting plate is in threaded connection with a second connecting column. An electric telescopic rod stretches out to push an adjusting block at the lower end of a push block to move downwards, the adjusting block extrudes a first torsion spring to be tightened, the first torsion spring also enables a pull rod to release force rightwards, a second torsion spring at the end of the pull rod releases pressure, and the second torsion spring extrudes and pushes a shifting block; the shifting block drives the connecting frame to perform angle deflection on the mounting plate, so that the lock opening in the fixing piece at the end of the connecting frame enters the lock block on the lock body, additional manual operation is not needed, and the effect of automatic opening and closing between the lock body and the fixing piece is achieved.
