A limit button device

Abstract

A limit button device, comprising a limit button body, a pedal, a skin and a rotating shaft, wherein the limit button body used to control the opening and closing of the pedal is riveted on the skin by rivets, and the limit button body is connected to the The foot pedal is connected, the rotating shaft is installed on the foot pedal, the body of the limit button is pressed by external force and slides along the cut corner of the foot pedal, and the opening and closing of the foot pedal is controlled by using the deformation recovery ability of the spring, so that it can be completed with one hand The random boarding device is retractable; the structure is simple, not restricted by the structure, and it is easy to retract, which effectively solves the problem that the pilot is inconvenient to retract and retract the boarding device after getting on and off the plane; and the footrest is flush with the skin to meet the aerodynamic characteristics of the aircraft Require.

Description

technical field [0001] The invention relates to the technical field of aircraft structures, in particular to a limit button device. Background technique [0002] The pilot usually boards the plane through the conventional boarding ladder or with the support of the wings first, and then steps on the random boarding device in the rear cockpit to complete the boarding. The random boarding device should be convenient for the pilot to complete the retracting action. Patent No. CN106477023A discloses a folding and flipping random boarding ladder, which is fixed in the slot of the lock ring through the lock keys of the two upper locks. Both hands cooperate to operate, and for the aircraft with a random boarding ladder in the rear cockpit, the uplock is not convenient for the rear cockpit pilot to close the ladder after boarding; When colliding with an object, the lower hard point under the hood of the vehicle will damage the object. However, due to its complex structure, high matc...
