Abstract

The utility model discloses a mechanical digital door lock core that comprises an upper cover board, a lower cover board, a barrier strip, an upper dead plate, a unlocking bracer, a lower dead plate, a digital strip pallet, a locking sheet, a fixed leg and at least three digital units. The digital unit comprises a digital strip, a rack and a cutter arranged on the rack. The dead plate of the cutter is fixed and connection with the upper dead plate. The cutter is stuck at left and right ends of the socket arranged on the dead plate of the cutter through two openings opposite openings in left and right sides arranged in front of the cutter. The tail end of the cutter is provided with two stop legs which are stuck in a spring bearing on the latter dead plate of the cutter. A stripper plate which is bending downwards like an opening-bracket-symbol is arranged in the middle of the cutter. The stripper plate goes through the openings on the upper dead plate and the unlocking bracer, so that the lower end of the opening-bracket-symbol-shaped bending is placed right on the digital gear of the digital strip. The mechanical digital door lock core of the utility model improves the digital units, so the cutter does not get deformed or damaged easily, thus prolonging service life and increasing the security of the mechanical digital door lock core.
