The invention belongs to the technical field of aviation technical structural design, and particularly relates to a cabin door shielding and sealing composite functional structure, which is characterized in that a door frame is designed on the periphery of a fuselage, a belly cabin door shielding and sealing tape is fixed on the door frame through a pressing block, and primer is removed from a position, corresponding to the sealing tape, on a belly emergency cabin door; removing the primer at the contact position of the pressing block and the engine belly emergency cabin door frame to ensure that an electric path is formed; when the cabin door is closed, the airtight, watertight and electromagnetic shielding requirements of the cabin door are ensured through contact compression of the sealing tape and the door frame. The belly emergency cabin door sealing tape needs to solve the problems of frequent trampling abrasion of a user, difficult door closing, easy debonding and the like of the sealing tape.

    本发明属于航空技术结构设计技术领域,具体涉及一种用于舱门屏蔽密封复合功能结构,在机身周圈设计门框,将机腹舱门屏蔽密封带通过压块固定在门框上,在机腹应急舱门上与密封带对应的位置上褪除底漆,在压块与机腹应急舱门门框接触的位置褪除底漆确保形成电通路;舱门关闭时通过密封带与门框接触压缩保证舱门的气密、水密和电磁屏蔽要求。本发明机腹应急舱门密封带需解决用户频繁踩踏磨损问题、密封带的难关门、易脱粘等问题。
