Coded mechanical lock

The invention refers to a coded mechanical lock designed for the locking of special use rooms, warehouses, lockers, private homes, etc. The coded mechanical lock is made up of several active rods (3) and passive rods (4), supported by recoil springs (14), which go through the door panel and exit to the exterior of the room through an inscribed plate (10). The rods (3 and 4) are connected to discs (5) that can penetrate holes (f) made in a plate with holes (7), laterally guided by spigots (6). The plate with holes (7) is supported on a weighted lever (20) which, through a blocking bolt (19), releases or blocks a locking catch (2) with translation movement, that can be moved in the "closed" or "open" position through the rotation of handles (12), connected to an activating spindle (11) that has a toothed section.
