Sealed undercarriage control handle with locking and unlocking functions

Abstract

The invention discloses a sealed undercarriage control handle with locking and unlocking functions. The sealed undercarriage control handle comprises a handle operating component, a transient dynamic mechanism and a locking and unlocking component, and is characterized in that the handle operating component comprises a handle (2), a clamping plate (25) and a cam (33); the clamping plate (25) is fixedly mounted on a mounting plate (14); the handle (2) is rotatably connected with the clamping plate (25); the cam (33) is mounted at the lower end of the handle (2) and is rotationally matched with the mounting plate (14) and a bushing (26); the transient dynamic mechanism comprises a pillar (36), a piston (13), a guide cylinder (11) and a swing plate (9); the pillar (36) is mounted at the lower end of the handle (2) and is rotationally matched with the piston (13); the piston (13) is matched with the guide cylinder (11) in a sliding manner; the swing plate (9) is rotatably mounted at the tail end of the guide cylinder (11); and a leaf spring (24) and a microswitch (23) are fixed on the mounting plate (14). The sealed undercarriage control handle is reliable in performance, is safe and practical, and is suitable for being popularized and applied in handle locking and unlocking operations of aircrafts.

Description

technical field [0001] The invention belongs to the technical field of landing gear control handles, and in particular relates to a sealed landing gear control handle with locking and unlocking functions. Background technique [0002] The joystick is very important for controlling the retraction and retraction of the landing gear, and the reliability of its locking and unlocking directly affects the safety of the aircraft. In the prior art, the joystick mainly has the following problems: (1) The structure is complex and takes up a large space, which is not suitable for the limited control space of the aircraft; (2) The reliability of unlocking and locking is poor, and there are certain safety hazards; (3) The operation process Unsmooth, poor hand feeling and sometimes misoperation; (4) The rainproof and dustproof effect is not obvious. Many of the above problems have been unable to meet the higher technical requirements of modern advanced aircraft for landing gear. Conten...
