At this time, the explosion-proof steel plate 2 and the explosion-proof glass 21 can be removed and replaced.

[0034] Step 2: Fix the door frame 1 to the door door of the cabin body with bolts, seal the connecting gap between the door frame 1 and the cabin body with the second explosion-proof sealing strip 16, lock the door panel 11 in the door frame 1 with the locking handrail 31 in cooperation with the locking block 3, seal the connecting gap between the door panel 11 and the door frame 1 with the first explosion-proof sealing strip 12, and prevent the shock wave and flame generated by the explosion from entering the cabin by the cooperation of the first explosion-proof sealing strip 12 and the second explosion-proof sealing strip 16.

[0035] Step 3: Rotate the locking armrest 31 to separate it from the locking block 3. At this time, push the door panel 11 outward to make it flip outward with the heavy hinge 13 as the center, so as to open the escape door. When the door panel 11 is opened, the door panel 11 can be easily opened with the help of the pneumatic strut 32 to achieve escape, thereby greatly improving the convenience and reliability of escape.
