Claims

[Claims for Utility Model Registration] (1) An outer cylinder, an inner cylinder having a keyhole, a plurality of pin tumblers housed in accommodation holes extending from the outer cylinder and the inner cylinder to the keyhole, and each of the above-mentioned pin tumblers. A cylinder lock comprising a plurality of switches corresponding to each pin tumbler, a latching mechanism, a warning mechanism, and an electronic circuit that can be controlled by the plurality of switches to operate the latching mechanism and the warning mechanism, Each of the switches includes a spike and an elastic conductor, and each of the spikes is fixed to a corresponding one of the pin tumblers, and
The elastic conductor is configured to protrude from the outer cylinder, the elastic conductor is configured to be fixed to the outer cylinder via an insulator, and when the spike is raised by a corresponding pin tumbler, The cylinder lock is configured to contact the elastic conductor to form a closed loop, and the cylinder lock further includes a control pin tumbler having a switch, the switch having a spike fixed to the control pin tumbler; and an elastic conductor fixed to the outer cylinder via an insulator, the control pin tumbler is housed in a housing hole provided in the inner part of the outer cylinder, and its lower end is connected to the inner part of the outer cylinder. The control pin is configured to contact a slot formed on the surface of the cylinder, and when the inner cylinder rotates, the slot slopes to bring the spike fixed to the control pin tumbler into contact with the elastic conductor; The latching mechanism includes a latch disposed on a seat and made of a ferromagnetic material, and a solenoid connected to the electronic circuit, and when the solenoid is actuated by the electronic circuit, the seat moves and latches the latch. is configured to engage with a latch engagement hole formed in the inner cylinder to inhibit rotation of the inner cylinder, and the electronic circuit is configured to connect to a battery set and a switch corresponding to each of the pin tumblers. a plurality of switches connected to each other, another switch connected to the switch corresponding to the control pin tumbler, an integral circuit for delaying the operation of the latching mechanism and the warning mechanism, and the above control pin tumbler through a relay. a trigger circuit for controlling the operation of the warning mechanism and the latching mechanism; and a battery test circuit capable of generating a warning signal by the warning mechanism when the voltage level of the battery set drops below a predetermined level. The electronic circuit is configured such that when an incorrect key is inserted into the keyhole, the trigger circuit activates the relay and locks the latch after a predetermined period of time controlled by the integral circuit. The warning mechanism and the solenoid are activated to engage the latch engagement hole and prohibit the rotation of the inner cylinder, and when the correct key is inserted into the keyhole, the pin tumbler and the corresponding switch are activated. A cylinder lock characterized in that the trigger circuit, the latching mechanism and the warning mechanism can be deactivated when a switch corresponding to the control pin tumbler is also turned on. (2) The cylinder lock according to claim 1, wherein the warning mechanism is a buzzer.
