A pressure relief covering cap mechanism with overpressure protection function relates to the technical field of aircraft structure design, the pressure relief covering cap is provided with bearings and a double-ear connecting seat, the double-ear connecting seat is in shaft driving connection with a lock mechanism pulling rod, pressure relief covering cap spacer pins are mounted on the bearings, a pressure relief covering cap rotation shaft is mounted on a cabin door structure, and a torsion spring is arranged on the pressure relief covering cap rotation shaft and between the bearings. One end of the shaft of the pressure relief covering cap mechanism is provided with a limit stop block, and the other end of the pressure relief covering cap mechanism is provided with is provided with a double-ear mechanism pulling rod, and double-ear pieces of the double-ear mechanism pulling rod are in shaft driving connection with a control mechanism pulling rod. The pressure relief covering cap mechanism with overpressure protection function converts overpressure operation alarm function into overpressure operation prohibition function, improves cabin door operational operation safety, and is high in device stability, safe and reliable.
