Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of special vehicles, and in particular relates to an escape door suitable for special vehicles for people to escape from the bottom of the vehicle in an emergency. Background technique [0002] Most of the existing special vehicles use window and door structures with hinge mechanisms, and in order to ensure the sealing performance of the vehicles, the existing windows and doors are designed with various locking mechanisms such as lock hooks and pressure plates. When realizing the rapid escape of the occupants in the vehicle within a short period of time, the traditional window and door locking mechanism will greatly increase the opening time of the windows and doors due to the long release time and large operating space, which will reduce the escape rate of the occupants in the vehicle in an emergency At the same time, because most of the windows and doors are opened by hinges, when the windows and doors are...
