Pop-up cargo hold door outer handle operating mechanism
The invention belongs to the field of airplane pop-up cargo hold door outer handle operating mechanism design, and particularly relates to a pop-up cargo hold door outer handle operating mechanism which comprises a handle box, a handle, a handle lock, a rocker arm, a pull rod and a compression spring. The handle is arranged in an opening of the airplane cabin door; a handle shaft is arranged on the inner side of the handle; the handle box comprises a box body and a supporting frame on the outer side of the box body. The tail end of the supporting frame is provided with an end cover sleeved at the tail end of the handle shaft, and one end of the compression spring abuts against the bottom of the central blind hole and abuts against the end cover at the other end. A rocker arm hinged with the pull rod can axially and movably sleeve the outer side of the handle shaft through a spline; the handle lock comprises a torsion spring, a hinge shaft, a lock shaft and a lock body; during locking, the lock hook is hung on the lock shaft, during unlocking, the unlocking button is pressed, the lock hook is separated from the lock shaft, and the handle pops out of the airplane cabin door under the action of the pressure spring. During locking, the handle is pressed, the inclined plane of the lock hook is in contact with the lock shaft to push away the torsion spring and lock.
本申请属于飞机弹出式货舱门外手柄操作机构设计领域，特别涉及一种弹出式货舱门外手柄操作机构，包括：手柄盒、手柄、手柄锁、摇臂、拉杆以及压簧；手柄置于飞机舱门的开孔中，手柄内侧具有手柄轴；手柄盒包括盒体以及盒体外侧的支撑架；支撑架的末端具有套在手柄轴末端的端盖，压簧一端抵在中心盲孔底部，抵在另一端端盖上；与拉杆铰接的摇臂通过花键可轴向移动套在手柄轴外侧；手柄锁包括扭簧、铰接轴、锁轴以及锁体；锁定时，锁钩挂在锁轴上，开锁时，按压开锁按钮锁钩脱离锁轴，手柄在压簧作用下弹出飞机舱门；上锁时，按压手柄，锁钩具有的斜面与锁轴接触推开扭簧并上锁。
