Double-system lock for a key-locking mechanism has a casing with a through-hole and a link to a collet along with a number-recognition plate and numerical wheels

摘要

Several apertures (112) fit on a casing (1) that houses a combination lock mechanism (2). There is also a number-recognition press plate (NRPP) (21) as well as numerical wheels (22), a pressure plate (23), a displaceable locking element (24) and a flexible element (25). The NRPP has through-holes (211). Each end of a numerical wheel matches an aperture and a through-hole.
