Synchronous linkage locking device for universal aircraft cabin door

Abstract

The invention belongs to the technical field of aircraft production, in particular to a synchronous linkage locking device for an universal aircraft cabin door. The device comprises a fuselage, the fuselage comprises a front cabin, a rear cabin and a cabin door for simultaneously closing the front cabin and the rear cabin, the synchronous linkage locking device further includes a linkage locking mechanism and a rear cabin locking mechanism, the linkage locking mechanism includes a locking portion installed at an edge of the cabin door, a front cabin locking assembly and a rear cabin locking assembly, the rear cabin locking mechanism includes a locking assembly and a handle assembly, the locking assembly includes an inserting rod set, and the locking portion includes a connecting strip plate and a plurality of buckles, the device ensures that flight students and coaches can enter and exit the front and rear cabins at the same time and the students do not panic and jump from the cabins,and under the emergency circumstances when the students experience fainting but the coaches cannot operate aircraft in the rear cabin, the coaches can open the cabin door alone, buy time for self-rescue by the coaches and students, and reduce serious losses.

Description

technical field [0001] The invention belongs to the technical field of aircraft production, and in particular relates to a synchronous linkage locking device for a general aircraft cabin door. Background technique [0002] When student pilots are conducting flight training, the flight instructor usually sits in the back cabin of the student pilots and can take over the student pilots to operate the aircraft. Now, the doors of the front cabin and the rear cabin of some training aircraft are opened separately, but In the event of an accident, the psychological quality of the student pilots is not up to standard. When opening the front cabin, they will rush to parachute, and it is difficult to guarantee the safety of the instructor. For some situations, the instructor can handle them, but the psychological quality of the student pilots is not up to standard, resulting in some serious accidents. losses, and even life-threatening risks.
