The utility model relates to hardware products, and specifically to safe locks which are opened after an insertable code combination coincides with a secret code. The technical result of using the device is a simplification of the design and manufacturing process, and also an increase in security by means of sound insulation, elimination of clearances in the contacts of the metal components and creation of acoustic interference which obstructs selection of the code. The safe lock comprises a hasp with a drive, a security part in the form of coded discs with external projections and depressions, wherein one of the depressions is coded while the remaining depressions are decoys, and a pin which is connected to the hasp and can interact with the coded depression. The hasp drive is in the form of a crank with a threaded end which is connected to a nut on the door and to a wrench. Each of the coded discs has a dedicated spindle dismountably connected to the spindle of the code selector wrench with a limb. The pins which lie opposite each coded disc are secured by means of a vertical rod, wherein the lock is equipped with an acoustic interference generator which is in the form of a rotatable, spring-loaded, L-shaped lever having a noise-creating furrow which is joined to the spindle of the code selector wrench. In an assembled state, the spindle of the coded disc and the spindle of the code selector wrench are equipped with a limiter of the longitudinal movement N thereof, the magnitude of which is less than the width of the pin and ensures at least one revolution of angular movement of the coded disc. Elastic sound-absorbing linings and bushings are mounted between the joined metal components, and the selector spindle is spring-loaded. Individual components are formed from plastics materials. |
