Abstract
The present disclosure provides an alarming code lock, including a lock head and a steel wire rope. A warning device, a circuit board, and a trigger switch are disposed inside the lock head. The warning device and the trigger switch are electrically connected with the circuit board. One end of the steel wire rope is fixedly connected with the lock head and is electrically connected with the circuit board. A plug is disposed on another end of the steel wire rope. The plug is inserted into the lock head and then makes contact with the trigger switch. The steel wire rope and the circuit board form a protection circuit, and the warning device is configured to raise an alarm when the plug keeps in contact with the trigger switch and the protection circuit is disconnected.
