Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a door locking device resistant to illegal unlocking with a picking tool and capable of positive protection of equipment to be intended against illegal access.
SOLUTION: A mount box 3 is fixed to the inner face of a side wall plate portion 2b of a fixed frame 2 apart from a door 10 and a cylinder lock 5 is fixed to an inner wall portion 3b of the mount box 3. One end of a core wire 7a of an association wire member 7 is connected to a rotating operation plate 6 fixed to a rotor 5a of the cylinder lock 5 so that a latch 8 connected to the other end of the core wire 7a can be engaged/disengaged with/from a receiving bracket 12 fixed to the back of the door 10. Since a locking mechanism portion is located behind the inner corner of the fixed frame 2, a neck length key 13 long enough to reach the cylinder lock 5 is only used for operation.
