Abstract

The utility model relates to mechanical digital lock, in particular to a mechanical emergency unlocking device. A digital disc is provided with a mini shallow slot and a locking and clamping slot and fixedly coaxially connected with a synchronous drive gear which is meshed with a transmission gear; the transmission gear is also meshed with a starting gear of a turner, and the starting gear is arranged at the bottom threaded end of a spring strut protruding from a mandrel of the tuner; the tail end of the mandrel is in tight contact with a locking and clamping plate controlling device; the swinging end of a controller is in compressing joint with the tail end of the mandrel; the locking and clamping edge of the locking and clamping plate corresponds to and matches with the locking and clamping slot of the digital disc; a sliding chute parallel to the locking and clamping edge is disposed in the middle of a bottom plate, and a guiding pin slides in the sliding chute; and an unlocking controlling rod of a controlling edge is clamped in a controlling and clamping slot of the controller. Because no locking hole is arranged, the mechanical digital lock has high password setting property and strengthened security guard property, is convenient to memorize only two codes needed and has wide application range.
