    • The cylinder lock according to the present invention comprises a latch 19 movably disposed between the joint position connecting the key cylinder 16 and a driver 18 and the release position disengaging the key cylinder 16 and a driver 18; and a clutch 20 for transferring the latch 19 to the release position when a sleeve 13 rotates relatively to a housing 11 with an improper key. When a proper key is inserted into the key cylinder 16, it can be rotated without rotation of the sleeve 13 so that the driver 18 can be rotated to the locked or unlocked position through the latch 19 which drivingly connects the key cylinder 16 and the driver 18. When an improper key is inserted into the key cylinder 16 and rotated, the sleeve 13 is rotated with the key cylinder 16 through tumblers 17 so that radial movement of the clutch 20 disengages the latch 19 and driver 18, thereby preventing unauthorized unlocking of the cylinder lock 10 without rotation of the driver 18.
    • 根据本发明的气缸锁包括可移动地设置在连接钥匙筒16和驾驶员18的关节位置之间的闩锁19和脱离钥匙筒16的释放位置和驱动器18; 以及离合器20,用于当套筒13以不适当的钥匙相对于壳体11旋转时,将闩锁19转移到释放位置。 当将适当的钥匙插入钥匙筒16中时,其可以不旋转套筒13而旋转,使得驾驶员18能够通过锁扣19旋转到锁定或解锁的位置,闩锁19驱动地连接钥匙筒16和驱动器 当将不正确的钥匙插入钥匙筒16并旋转时,套筒13随着钥匙筒16通过翻转开关17而转动,使得离合器20的径向运动脱离闩锁19和驱动器18,从而防止未经授权的解锁 气缸锁10没有旋转驱动器18。
