LOCALIZING SECURITY GATEWAY OF NUCLEAR PLANT WITH LEVERED DOOR LOCKING MECHANISM Russian patent published in 2022 - IPC G21F7/05 

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, namely to nuclear energy, in particular to equipment installed in the containment shells of nuclear reactors of an operating nuclear power plant and providing access for personnel to the hermetic enclosure of the reactor plant. The gateway of the localizing security system of a nuclear power plant with a lever mechanism for locking doors includes a body and doors. The door is locked using a lever mechanism consisting of a rocking lever with rollers. The rollers are rolled onto the supporting inclined surface of the door bracket, which has the possibility of locking the door when the roller passes through the projection of the axis of the rocking lever onto the supporting surface of the door bracket.
