Gear transmission type mechanical anti-theft lock
The invention discloses a gear transmission type mechanical anti-theft lock, and relates to the field of mechanical anti-theft locks. The gear transmission type mechanical anti-theft lock is characterized in that a key hole and a handle rotating shaft are horizontally arranged, a key is formed by connecting a plurality of pinions in series, each pinion is a complete gear or an incomplete gear or has zero teeth, and the key drives each rack to run for different distances through an intermediate gear. After the key is rotated by a circle, a handle drives a cam to push a locking plate to be inserted into sawteeth of the racks firstly, 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 continues to rotate to achieve unlocking. If the key is incorrect, the locking plate still clamps all the racks and cannot move, 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 handle is strongly twisted, the handle idles; and the lock is locked only needing to reversely lift the handle without the key. The mechanism is simple in structure, low in manufacturing cost and easy to install, and the lock has the characteristics of technical unlocking prevention, damage unlocking prevention, large secret key amount, stability, durability and the like.
一种齿轮传动式机械防盗锁，涉及机械防盗锁领域，其钥匙孔与执手转轴水平设置，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。上述机构结构简单、造价低、易安装，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。
