Prying-resistant lock for automobile rear cover box
The invention relates to an automobile lock, in particular to a prying-resistant lock for an automobile rear cover box. The prying-resistant lock for the automobile rear cover box is mainly composed of a lock seat, a lock cylinder, a telescopic rod and a damping positioning device. The prying-resistant lock for the automobile rear cover box is characterized in that the telescopic rod is connected with a cam-shaped rotating propeller at the tail end of the lock cylinder; the telescopic rod is arranged in the lock seat and abuts against the rotating propeller through a spring; one end of an outer circular ring of the lock cylinder is provided with a channel for allowing in and out of part of the telescopic rod; the damping positioning device is arranged between the lock seat and the lock cylinder; the lock seat is fixed to a trunk cover or an automobile body; the other end of the telescopic rod is clamped in a groove of an original automobile lock. When the lock cylinder is pried forcibly, due to the action of the damping positioning device, the lock cylinder and the outer circular ring do not rotate relatively due to the fact that a key is not consistent, the telescopic rod can only abuts against the outer circular ring part of the lock cylinder at that time, and the telescopic rod cannot come back to the channel of the outer circular ring of the lock cylinder, so that the telescopic also does not come back from the groove of the original automobile lock, and therefore the effects of prying resistant and protecting are achieved.
