In one embodiment, as shown in fig. 1, there is provided a security lock cylinder comprising: the lock comprises a lock shell 6, a circuit board, an alarm trigger device, a lock cylinder assembly, a lock cylinder connecting rod, an angle adjusting assembly and a lock cylinder ruler 15, wherein the circuit board, the lock cylinder connecting rod and the angle adjusting assembly are all fixedly arranged inside the lock shell 6, the lock cylinder assembly is connected with the lock cylinder connecting rod, the lock cylinder connecting rod is connected with the angle adjusting assembly, and the angle adjusting assembly is connected with the lock cylinder ruler 15; the alarm trigger device is arranged on the lock cylinder assembly and triggers the alarm trigger device to alarm when the technical tool is inserted into the lock cylinder assembly.

Specifically, the lock shell 6 covers other parts of the lock cylinder therein, and plays a role in protecting the parts of the lock cylinder. After the user inserted mechanical key 1 into lock courage subassembly, if the key is correct, the accessible rotated mechanical key 1 and drove the rotation of lock courage connecting rod, and lock courage connecting rod drives the spring bolt that mechanical lock body was stirred to lock core chi 15 through angle adjusting part and opens the door. It will be appreciated that if the key is inserted incorrectly, the door cannot be opened. The angle adjusting component is used for adapting to different lock body unlocking angles, and the angle adjusting component is specifically combined with the rotation angle of the key and the rotation angle of the lock core ruler 15 to be set so as to adjust the angle of the lock core ruler 15 rotating along with the key. The lock core component is used as a carrier of a lock core blade (marble) structure, and different blades (marbles) are arranged and combined to match different mechanical keys 1. When a technical tool or a key is inserted into the lock cylinder assembly, the blade inside the lock cylinder assembly is pushed to touch the alarm trigger device, so that the alarm trigger device gives an alarm. The circuit board can be used for controlling the lock core to unlock, lock and limit. In addition, the circuit board can be connected with an alarm trigger device to control the alarm trigger device to work, so that the intelligent degree of the safety lock cylinder is improved.
