Abstract

A cylinder lock device (10) includes a lever (15) rotatably disposed between a casing (11) and a key cylinder (13), and a blocking member (17) disposed within a notch (16) formed in the lever (15). A concavity (18) are formed on an inner wall of the casing (11) , and a chamfer (19) is formed on the key cylinder (13). When the lever (15) is in the locked position and the key cylinder (13) is further rotated to the dead-locked position over the locked position, the blocking member (17) moves away from the chamfer (19) of the key cylinder (13) and into the concavity (18) of the casing (11) . When the key is pulled out from the key cylinder in the dead-locked position, the locking device is forcibly maintained in the locked position to prevent unauthorized unlocking.
