FIELD: construction. ^ SUBSTANCE: code lock with a detachable coding mechanism with open, semi-closed and closed code discs is used as an add-on lock, a padlock and to close a key hole installed in the key lock door. The lock comprises a stepped stop entering an axial dead hole of a stepped bushing fixed on the door sheet. Movement of crossbars from one extreme position to the other one is done with a screw screwed into a holder rigidly connected to crossbars entering the door leaf slot, and is carried out when the detachable coding element is removed from the stepped stop, and the screw head is automatically stopped to move the crossbars with a stop disc as the detachable coding mechanism is set to the stop. The stepped bushing has a cross slot for a stop disc with a hole for a lock pin, rigidly connected with a lock disc, with a figure hole, with two slot holes for a screw head of crossbar movement, with a longitudinal slot for a lock pin and with a groove for a ledge of a sign disc and pads. The sign disc and a package of composite code discs with pads is pressed via a disc of plate shape with a cap nut. A ball is installed into the end of the threaded end of the stepped bushing, and an insert is put on the bottom of the dead hole. ^ EFFECT: increased operational reliability. ^ 1 cl, 8 dwg |
