Abstract

A double-layer lock core for a spring lock relates to a lock core, which solves the problem existing in a current spring lock of poor burglar-proof performance. The utility model changes the original lock core into a double-layer structure based on a structure of the current lock core of the sprig lock, wherein an internal lock core can relatively rotate, a key groove is fixed on the internal lock core, an external lock core is connected with a shifting block for opening the lock, and the lock is opened through adopting the internal lock core to drive the external lock core, the chamfer angle of billiards between the internal lock core and the external lock close to one side of the key groove is larger than the chamfer angle on the other end. The lock core of the utility model can be provided with an alarm switch device which is started when the internal lock core rotates individually, and the external lock core does not rotate. The double-layer lock core for the spring lock can be applied in all current spring locks, and also can be connected with a current alarm device.
