The invention discloses a false opening preventing structure for a discharging door of an ore discharging car, which belongs to the technical field of locomotive carriages. As the upper part of a door leaf is hinged on the carriage, a rotating shaft is arranged at the bottom of the carriage, a pull rod is arranged on the rotating shaft and the rotating shaft is hinged with the lower part of the door leaf through a connecting rod, the door leaf is opened and closed due to forward and reverse rotations of the rotating shaft; a pre-tensioning device is arranged on the carriage; a supporting device is arranged in a corresponding position of the door leaf; the pre-tensioning device is pressed through the supporting device so that the door leaf is subjected to an uninterrupted pre-tensioning force when being closed; therefore, a situation that the door is falsely opened when a door closing connecting rod mechanism loses a self-locking force due to force losing over a dead point is prevented.
