摘要： A cylinder lock has a cylinder lock holder with a rotor rotatably disposed therein. The rotor has a plurality of grooves, with a plurality of tumblers slidably disposed in the grooves. Holder grooves are provided in the cylinder lock holder for receiving the tumblers projecting out of the grooves of the rotor. The rotor is able to be rotated in the cylinder lock holder in response to the insertion of a key into the rotor by causing the tumblers to be retracted from the holder grooves. Rotation is disabled when the key is removed, the tumblers projecting back into the holder grooves under the action of a spring biasing the tumblers. The key is inserted through a plurality of key insertion holes in the tumblers. Tooth portions are formed at respective contact portions between the tumblers and the inner surface of the cylinder lock holder, the respective tooth portions being engaged with each other when the key is removed from the lock.

摘要翻译： 气缸锁具有气缸锁定保持器，其中可转动地设置有转子。 转子具有多个凹槽，多个滚筒可滑动地设置在凹槽中。 支撑槽设置在气缸锁定保持器中，用于接收从转子的槽突出的翻转开关。 响应于通过使制动栓从保持器槽缩回而将钥匙插入转子中，转子能够在气缸锁定保持器中旋转。 当钥匙被拆下时，旋转被禁用，在弹簧的作用下，翻转开关突出回到保持器凹槽中，从而使制动栓偏置。 钥匙通过滚筒中的多个钥匙插入孔插入。 在滚筒与滚筒锁定保持器的内表面之间的相应的接触部分处形成有齿部，当将钥匙从锁上取下时，相应的齿部彼此啮合。
