Novel electromechanical installation box

The utility model relates to the technical field of electromechanical boxes, and discloses a novel electromechanical installation box which comprises a box body, a box door is installed on the surface of the box body, a fixing cylinder is fixedly connected to the inner wall of the box body in a sleeved mode, and a fixing frame is connected to the inner wall of the fixing cylinder in a bolted mode. The motor rotates to drive the rotating block to rotate, the rotating block rotates to drive the heat dissipation plate to rotate, and the heat dissipation plate rotates to quickly discharge heat, so that the purpose of good heat dissipation efficiency can be achieved, the stability of the electromechanical equipment is ensured, the damage of the electromechanical equipment is avoided, and the service life is prolonged; when the box body vibrates, the telescopic rod vibrates, the sliding plate moves when the telescopic rod vibrates, the sliding plate moves to enable air in the base not to be discharged from the air
