FIG. 2 shows an embodiment of the present invention. The main structure of the locking device for the door 2 of the box is a handle with a key 3, a driving plate 10, and a movable plate 1.
1, an arm 5 and a set screw 12. Drive plate 10
Has a square hole, and is inserted into the square shaft of the keyed handle 3 and fixed. The arm 5 is connected to the movable plate 11, and the arm 5 moves up and down by the rotation of the movable plate 11. The center hole of the movable plate 11 is larger than the diagonal dimension of the square shaft portion of the keyed handle 3. The rotation of the keyed handle 3 is not directly transmitted because it is large. The driving plate 10 and the movable plate 11 are always fastened and connected by a set screw 12, and in this state, the door 2 is locked by rotating the driving handle 3 with the key 3 to lock the door 2.
Then, the movable plate 11 is rotated, and the arm 5 is caught on the door frame 6 so that the door 2 is not opened and the keyed handle 3 is locked. The locked handle 3 does not rotate in the locked state, but the movable plate 11 is separated from the drive plate 10 by removing the set screw 12, so that the movable plate 11 and the arm 5 can be moved, as shown in FIG. The arm 5 caught on the door frame 6 can be easily removed by pulling it by hand, and the door 2 can be opened from the inside while the keyed handle 3 is locked.
