Abstract
The utility model discloses a mechanical cylinder letter door lock which is composed of an inner lock handle, a lock bolt box, an outer lock handle, a middle shaft, a lock core and a front cover. The inner lock handle is arranged on the lock bolt box to directly drive a lock bolt. The middle shaft is vertically arranged on the outer lock handle to form a telescopic engaging and disengaging drive with the lock bolt. The front cover is composed of a cover ring, a letter disc and a spring baffle sheet. The letter disc forms a rotating movable fit with the cover ring, and a telescopic movable fit with the middle shaft. The lock core is composed of a barrel, a lock sheet and a guide pin sheet arranged in the barrel. The cover ring, the barrel and the lock bolt box are integrally fixed. The middle shaft can orderly penetrate through the lock sheet and guide pin sheet which forms into a whole with the middle shaft.
