Abstract
The invention discloses a push-type automatic steering wheel lock. An outer pipe is fixedly connected with a lock cylinder shell. One end of a lock bar with radial grooves on the outer wall of the lock bar can be axially and slideably arranged in the lock cylinder shell and the outer pipe in a penetrating way. A first lock hook and a second lock hook are arranged on the lock bar and the outer pipe. The lock cylinder can axially slide and can be circumferentially inserted into a lock cylinder hole in the lock cylinder shell. A key can drive the lock cylinder to rotate. One end of the lock cylinder opposite to the lock bar can stretch out of the external side of the lock cylinder shell. The other end of the lock cylinder elastically presses against the inner wall of the lock cylinder hole of the lock cylinder shell. The other end of lock cylinder is additionally provided with axial bulges which can be held in the grooves on the external side of the lock bar. A radial stop hole is arranged in the outer wall of the lock cylinder. A stop which can axially and elastically extend and retract is arranged in the stop hole. One end of the stop oppositeback to the lock cylinder stretches out of the external side surface of the circumference of the lock cylinder. A radial inwards-concave limiting groove is arranged on the inner wall of the lock cylinder hole. The stop can just be held in and slide out of the limiting groove. The push-type automatic steering wheel lock has the advantages that the lock is convenient and safe to use, the automobile lock can be locked without using the key and the locking time is saved.
