Aircraft handle locking device

Abstract

The embodiment of the invention discloses an airplane handle locking device. The device comprises a locking assembly arranged on an airplane door frame plate and a lock shaft arranged on an airplane handle; the lock shaft comprises a shaft body arranged inside the handle and a locking connector located outside the handle, and the axial movement of the handle drives the lock shaft to axially move;the locking assembly comprises a lock hook and a fixing sleeve used for fixedly connecting the first end of the lock hook to the airplane door frame plate, a hook-shaped lock groove matched with the locking connector for locking is formed in the second end of the lock hook, and the locking connector is clamped into the hook-shaped lock groove in the lock hook when the lock shaft is driven by the handle; and the lock hook assembly further comprises a spring mechanism connected with the lock hook, and the spring mechanism is configured to release the lock shaft by pressing the second end of thelock hook. According to the embodiment, a handle locking device which is simple in structure and light in weight on the premise of meeting the use functions is provided.

Description

technical field [0001] This application relates to but is not limited to the field of aviation technology, especially an aircraft handle locking device. Background technique [0002] The doors and flaps on the aircraft that are opened by the handle are often opened due to false triggers and accidental operations during the field use, resulting in the inability to complete follow-up tasks. In addition, due to poor design of hatches and flaps, large deformation due to poor rigidity, and low reliability of handle locks, the locks may accidentally be unlocked and fly off in the air, thereby damaging other structures. In severe cases, they may enter the air intake and damage engine blades. [0003] Therefore, it is required to reasonably arrange the hatch in a limited space and a position with a large curvature, to open it conveniently and quickly by operating the handle lock, and to ensure the reliability of the handle lock. [0004] A handle locking device with small space occ...

[0002] The doors and hatches on the aircraft that are opened by the handle are often opened due to false triggers and accidental operations during the field use, resulting in the inability to complete follow-up tasks

In addition, due to the poor design of the hatch and the cover, the rigidity difference is large and the deformation is large, and the reliability of the handle lock is low, the lock is accidentally opened in the air and flies off, thereby damaging other structures, and in severe cases, it enters the air inlet and damages the engine blades.
