  • the lock mechanism When the lock mechanism is in a locked status, there will be two different locking mechanisms to provide the desired locking effect, namely the conventional latching mechanism in the lock core 7 and the coupling device. If a user is trying to unlock the lock mechanism, the user will have to unlock the lock core 7 and the clutch device of the lock mechanism sequentially, otherwise the buzzer 95 will sound an alarm to warn the security guard that there is an illegal action going on. To be more specific of the operation of the lock mechanism, it is to be noted that before the key 99 is inserted into the lock core 7, the multiple tumblers will lock the lock core 7 to prevent the lock core 7 from rotation such that the lock mechanism is locked. Because how the tumblers lock the lock core 7 is conventional in the art, detailed description thereof is omitted for brevity.
  • the first rotation circuit board 123 and the second rotation circuit board 127 are fixed so that there is no signal transmitted to the master circuit board 89 to drive the motor 69 to move.
  • the third clutch 133 and the first clutch 109 are received in the rotor 81 and thus the first blocks 111 of the first clutch 109 and the second blocks 137 of the third clutch 133 are received in the first slit 83 of the rotor 81 to disable the rotation of the rotor 81.
  • a second locking effect is accomplished.
  • the tumblers are rearranged to allow the lock core 7 to be rotatable.
  • the conducting plate 103 of the chip 105 engages with the spring 23 such that code information in the chip 105 will be transmitted to the first rotation circuit board 123 via the spring 23.
  • the information is transmitted to the master circuit board 91 via the contacts 131 of the first rotation circuit board 123 and the second rotation circuit board 127.
  • the motor 69 is activated to drive the threaded bolt 71 to rotate.
  • the rotation of the threaded bolt 71 drives the third clutch 133 and the first clutch 109 to move toward the key 99 to allow the first blocks 137 and the second blocks 111 to be away from the first slit 83 and to allow engagement between the first clutch 109 and the second clutch 115, until the extension 147 of the seat 143 engages with one of the arms 151 of the conductor 149 such that the motor 69 is stopped. Therefore, rotation of the key 99 drives not only the lock core 7, but also the rotor 81 and thus the boss 79 of the cam 77 is driven to unlock the lock mechanism.
  • the motor 69 can be replaced by an electromagnetic valve that is connected to the third clutch 133 to drive the third clutch 133 to move linearly so as to accomplish the aforementioned objective.
