The invention relates to the technical field of elevator testing devices, and particularly to a door machine blocking device used for a door machine test. The door machine blocking device comprises a vertical fixed mounting plate; a middle lever rotating shaft which extends in the vertical direction is arranged at the position of the upper surface of the fixed mounting plate; a strip-shaped turning plate which extends in the horizontal direction is hinged to the middle lever rotating shaft; the turning plate when being in an initial state is arranged to cross with the fixed mounting plate, and the front end and the back end of the turning plate respectively go beyond the front plate surface and the back plate surface of the fixed mounting plate in the horizontal direction; a turning shaft which extends in the vertical direction is arranged on the position of the upper surface of the turning plate which nears the front end; a blocking turning wheel which is in the initial state and is at least partially dead against the side part of one side in the opening/closing direction of a tested door plate is arranged on the turning shaft in a sleeved manner; an elastic restoration device is arranged between the position of the back plate surface of the fixed mounting plate and the back end of the turning plate; the door machine blocking device is firm and steady in structure, convenient to assemble and disassemble and high in simulation degree.
