Abstract

The invention discloses a double-safety lock and a key thereof. According to the technical scheme, the double-safety lock is characterized in that the double-safety lock comprises a lock body, a lock cylinder hole and flat ball holes are formed in the lock body, flat ball assemblies are arranged in the flat ball holes, and a lock cylinder is arranged in the lock cylinder hole; a shifting head is arranged at one end of the lock cylinder; a key hole, marble holes, a safety bolt groove, sealing piece grooves and blade grooves are formed in the lock cylinder; marbles which are matched with the flat ball assemblies and enable the flat balls to lock the lock cylinder are arranged in the marble holes; and a safety bolt which can lock the lock cylinder is arranged in the safety bolt groove. According to the double-safety lock, the marbles are integrated in the lock, and the safety bolt can only be unlocked when the safety bolt is matched with the marbles and blades at the same time, so that the anti-theft coefficient is increased, and the safety performance is better; the marbles and the key are matched, so that the safety bolt can only rebound into the safety bolt groove by rotating the marbles by certain angles, and thus the anti-theft performance is further improved. By taking the double-safety measure based on the marbles and the safety bolt, the lock has a better anti-prying function, and the lock is extremely difficult to unlock even when damaged with violent force.
