The invention discloses a gear string key mechanical anti-theft lock, and relates to the field of mechanical anti-theft locks. A key hole and a handle rotating shaft are arranged on a same vertical line; a key is formed by connecting a plurality of small gears in series; each small gear is a complete gear, or an incomplete gear, or a gear with no tooth; and the key drives all racks to run for different distances through an intermediate gear. After the key is rotated for one circle, the handle drives a cam to firstly push a locking plate to be inserted into saw teeth of the racks, then the racks cannot move any more, the cam pushes an unlocking inserting plate to be inserted into rectangular openings of the racks, and the cam can continuing rotating for unlocking. When the key is incorrect,the locking plate can still clamp the racks firstly and the racks cannot move, but the unlocking inserting plates cannot be inserted into the rectangular openings, so that the cam is prevented from rotating, and the lock cannot be unlocked. If the handle is twisted strongly, the handle is idle. Locking can be completed without using a key but reversely lifting the handle. The racks, the intermediate gear and the like are simple in structure, can be stamped and processed, and are low in manufacturing cost. The lock has the characteristics of preventing technical unlocking, preventing unlockingby damage, large key amount, stability, durability and the like.
一种齿轮串匙机械防盗锁，涉及机械防盗锁领域，其钥匙孔与执手转轴在同一垂线上，钥匙由若干个小齿轮串连而成，各小齿轮为完整齿轮或不完全齿轮或齿数为零，钥匙通过中间齿轮驱动各齿条运行不同距离。旋转钥匙一周后，执手带动凸轮先推动锁止板插入齿条的锯齿中，各齿条不能再移动，凸轮再推动开锁插板插入各齿条的矩形开口中，凸轮能继续转动而开锁。钥匙不正确，锁止板仍先卡住各齿条不能移动，但开锁插板不能插入矩形开口，阻止凸轮转动，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。齿条、中间齿轮等结构简单、能冲压加工、造价低，锁具兼具防技术开启、防破坏开启、密钥量大、稳定耐用等特点。
