The utility model relates to an anti-falling device and an electric appliance cabinet, relates to the technical field of railway vehicles, and is used for solving the technical problem of failure of an anti-falling function of a door plate in the prior art. The utility model discloses an anti-falling device. The anti-falling device comprises a fixed seat and an anti-falling stop piece, the fixed seat is connected with the cabinet body; the anti-falling stop piece arranged on the anti-falling device in a sleeving mode can move. The door plate can be moved to the first position and is fixed on the cabinet body; therefore, according to the utility model, the door plate is fixed on the cabinet body through the anti-falling stop piece and the fixed seat, so as to take a secondary anti-falling measure on the door plate, thereby avoiding the phenomenon of failure of an anti-falling function due to the adoption of an anti-falling mode depending on the dead weight of the anti-falling piece.
