The invention discloses a mechanical lock. The mechanical lock comprises a front lock tube, a rear lock tube, an emergency lock cylinder, a lock rod and a shifting wheel, wherein the emergency lock cylinder and the lock rod are arranged in the front lock tube and the rear lock tube; the shifting wheel is arranged between the front lock tube and the rear lock tube and connected with the emergency lock cylinder and the lock rod through a separation and reunion assembly; a key groove of the emergency lock cylinder is a blind hole; a push block assembly is arranged between the emergency lock cylinder and the separation and reunion assembly; the push block assembly comprises a push block movably arranged in the rear portion of the emergency lock cylinder and a thrust column arranged on the push block in the radial direction; an inclined groove matched with the thrust column is formed in the side wall of the rear portion of the emergency lock cylinder; and a straight sliding groove matched with the thrust column on the push block and an annular sliding groove located in the rear end of the straight sliding groove are formed in the inner wall of the front lock tube. According to the mechanical lock, the key groove is designed to be the blind hole in the emergency lock cylinder, and the separation and reunion assembly is isolated from the key groove, so that the problem that a motor assembly idles and cannot be unlocked due to the fact that the lock rod is in an idling state when a tool is inserted into the key groove to push the separation and reunion assembly is fundamentally solved.
本发明公开了一种机械锁头，包括前锁管和后锁管、设在前锁管和后锁管内的应急锁芯和锁杆、设在前锁管和后锁管之间通过离合组件与应急锁芯和锁杆连接的拨轮；所述应急锁芯的钥匙槽为盲孔，所述应急锁芯与所述离合组件之间设有推块组件；所述推块组件包括活动设在应急锁芯后部内的推块和径向设在推块上的推力柱；所述应急锁芯的后部侧壁上设有与推力柱配合的斜槽，所述前锁管的内壁上设有与所述推块上的推力柱配合的直滑槽和位于直滑槽后端的环形滑槽。本发明通过在应急锁芯上将钥匙槽设计为盲孔，将离合组件与钥匙槽隔离，这样从根本上解决了通过工具插入钥匙槽推动离合组件，使得锁杆处于空转状态，导致电机组件空转无法开锁的问题。
