LOCKING DEVICE WITH A LOCK WITH A KEY CODE SET Russian patent published in 2022 - IPC E05B63/00 

FIELD: locking devices.

SUBSTANCE: invention relates to locking devices. The locking device contains a lock (1) and a mechanical code locking device with a ratchet mechanism, the code of which is typed by turning the lock key. The parts of the mechanical code locking device are located on its housing (2), fixed to the rear of the lock housing (1), and the rear of the shank (3) of the lock (1). Some parts of the ratchet mechanism: the fixing latch (7) and the ratchet (9) are spring-loaded and located on the axes mounted on the housing (2) of the code locking device with the possibility of rotation around these axes and interaction with each other. On the shank (3) of the lock (1) there is a spring-loaded latch (5) for driving the ratchet (9) and a cam (4) for interacting with the fixing latch (7). There is also a locking rack (11) located on the housing (1) of the code locking device near the ratchet (9), and a cam (12) located on the ratchet (9) in place of one of its teeth, which has the ability to interact with the locking rack (11) in the position when the latches (5) and (7) do not interact with the ratchet (9), as well as the cam (19) of the code set, which in a certain position of the ratchet (9) through the lever system has the ability to interact with the movable stop (17) located behind the shank (3), with the possibility of this stop crossing the trajectory of the shank (3) and interacting with it.

EFFECT: inaccessibility of the code locking device for outsiders is ensured, a significant number of key positions at which the lock is blocked, independence from power supply, lack of cables and battery.
