FIELD: applicable for level mortise and hasp locks for locking of doors of enhanced strength. SUBSTANCE: the secret block has semi-levels with secrecy semi-windows outlooking to one of the side faces positioned between the side members of the locking bolt on the guide posts movable from turning of the key. The semi-levels are spring-loaded in the direction of the key, separated by fixed plates installed on the same guide poles in the form at least of one stack. The secrecy half-windows on all semi- levels are made identical, and the code combination is made on the side faces of the semi-levels parallel in the direction of motion of the locking bolt. A common through slot for the common compression spring is made on the semi-levels and fixed plates of the stack, and the guide post that is nearest to the key is made fixed against turning of the key jointly with the movable semi-levels. EFFECT: enhanced secrecy of the lock and the capacity of mass assembly, and reduced possibility of unauthorized opening and cost of a single product. 6 dwg |
