Double-resistance anti-theft locking mechanism

The invention relates to an anti-theft locking mechanism, and belongs to the technical field of anti-theft locking mechanism structures. The double-resistance anti-theft locking mechanism is characterized in that the double-resistance anti-theft locking mechanism comprises a main spring bolt assembly, a locking plate assembly and a locking block assembly. The main spring bolt assembly is installed on a lock base plate, transversely moves on the lock base plate, and is used for locking and unlocking the locking mechanism. The locking plate assembly longitudinally slides on the lock base plate, is in linkage with the main spring bolt assembly and provides the positioning and locking function for the main spring bolt assembly. The locking block assembly is in linkage with the locking plate in a matched mode to lock or unlock the main spring bolt assembly. According to the double-resistance anti-theft locking mechanism, shear force exerted on the main spring bolt is effectively dispersed through combined action of the locking plate and the locking block which are designed on the two sides of the main spring bolt, so that the anti-pressure capacity of the anti-theft locking mechanism is greatly improved; the double-resistance anti-theft locking mechanism is simple in structure, compact in space, safe and reliable.
