Cabin door opening drive mechanism for torsion bar type airliner
The invention relates to a cabin door opening drive mechanism for a torsion bar type airliner. A driven bar is arranged on the upper end face of a suspension arm and rotationally connected with a connecting bar. The connecting bar is rotationally connected with a crank. The other end of the crank is connected with a torsion bar in a penetrating manner. A long sleeve is arranged on one side of the torsion bar. Torsion bar supporting seats are arranged at the two ends of the long sleeve respectively. The torsion bar is connected with the long sleeve through one torsion bar supporting seat. The other torsion bar supporting seat is arranged at the other end of the torsion bar and one side of the torsion bar supporting seat is connected with the crank. A short sleeve is arranged on the other side of the crank and the other torsion bar supporting seat is arranged on the other side of the short sleeve. A thin sleeve is rotationally connected to the crank and perpendicular to the torsion bar. A screw is fixedly connected to the lower portion of the thin sleeve. A support is fixedly connected to the lower end face of the screw. A pure bar-system mechanism is adopted and a four-bar mechanism is driven through the torsion bar to drive a cabin door, so that the mechanism is simple, operation is easy, reliability is high, and installation and adjustment are convenient.
