The invention provides a bottom escape door for a special vehicle. The escape door is of a manual type, a rocker arm handle is rotated to drive a rotating arm connected below to rotate around a support, the center hole of the rotating arm and the rotating arm support are installed in a matched mode through a graphite self-lubricating bearing, and the rotating arm drives four cranks and spring bolt connecting rods to be matched with spring bolts and spring bolt sliding ways to conduct crank sliding block movement. The linear movement of the spring bolts is achieved. The spring bolts are provided with wedge-shaped structures, the spring bolts are released from the door frame of the escape door when the spring bolt sliding ways conduct linear motion, and finally the release of the escape door is achieved. According to the invention, people in the vehicle can escape in emergency, and the people in the vehicle can be quickly transferred to the outside of the vehicle; a locking structure is reliable and is matched with pin joint fixation at the handle end of the rocker arm, so that the locking structure cannot be loosened under the condition that the rocker arm handle is not released; and by means of the quick dismounting function of a trunnion pin, people in a car can quickly open the escape door without using any tool in emergency.
