Spiral anti-theft lock with double locking mechanism
The invention provides a spiral anti-theft lock with a double locking mechanism. The spiral anti-theft lock with the double locking mechanism comprises an upper lock cylinder structural system, a lower lock cylinder structural system and a lockhole protection system, the upper lock cylinder structural system is connected with the lower lock cylinder structural system, the lockhole protection system is connected with the upper lock cylinder structural system, the upper end of a pushing rod is connected with a pushing table, the lower end of the pushing rod is connected with a lower lock cylinder structural rack through a pushing extrusion spring, the pushing rod is fixed in a pushing rod shrinkage hole, a locking drive rod is fixed at the lower end of the pushing table, and a locking drive hole is formed in the lower lock cylinder structural rack corresponding to the locking drive rod. The spiral anti-theft lock with the double locking mechanism has the advantages that by means of the double locking mechanism and the spiral pushing locking principle, the anti-theft chances of the anti-theft lock can be effectively improved, and the safety performance of the anti-theft lock is improved.
