Incomplete gear driven thief resistant machine lock
The invention provides an incomplete gear driven thief resistant machine lock, and relates to the field of thief resistant machine locks. A key of the thief resistant machine lock is formed by connecting a plurality of short-tooth pinions with the same parameters in series, and the pinions are incomplete gears or complete gears or have zero tooth number and are meshed with spur racks on sliding plates correspondingly; after the key is rotated by a circle, the key drives the sliding plates to operate by different distances, then a lever handle drives a cam to push a locking plate to be insertedinto sawteeth of the sliding plates firstly, then the sliding plates cannot move any more, the cam pushes an unlocking inserting plate to be inserted into rectangular openings of the sliding plates,and the cam continues to rotate to unlock; if the key is unmatched, the locking plate still clamps all the sliding plates and avoids the sliding plates from moving, but the unlocking inserting plate cannot be inserted into the rectangular openings, so that the cam is prevented from continuously rotating, and the lock cannot be unlocked; if the lever handle is strongly twisted, the lever handle idles; and the lock is locked without the key, and the lever handle is reversely lifted to complete locking. The lock is simple in structure, low in manufacturing cost and easy to install, and has the advantages of being resistant to technical unlocking and damage unlocking, large in secret key amount, stable, durable and the like.
一种不完全齿轮驱动式机械防盗锁，涉及机械防盗锁领域，其钥匙由若干个相同参数的短齿小齿轮串连而成，各小齿轮为不完全齿轮或完整齿轮或齿数为零，并分别与各滑板上的直齿条啮合。旋转钥匙一周后，钥匙驱动各滑板运行不同距离，之后执手带动凸轮先推动锁止板插入各滑板的锯齿中，各滑板不能再移动，凸轮再推动开锁插板插入各滑板的矩形开口中，凸轮继续转动而开锁。钥匙不正确，锁止板仍先卡住各滑板不能移动，但开锁插板不能插入矩形开口中，阻止凸轮继续转动，锁具不能开启。若强力扭转执手，执手空转。上锁不用钥匙，反提执手完成。锁具结构简单、造价低、易安装，并兼具防技术开启、防破坏开启、密钥量大、稳定耐用等特点。
