Airplane door gust lock device

Abstract

A gust lock device for an aircraft cabin door can be positioned accurately and can improve the accuracy of locking and unlocking. The aircraft door gust lock device locks the aircraft door in a fixed position to lock the door in the maximum open state, including: a locked part, which is fixedly installed on the door frame of the door, and has a locked part and a locking part, which is installed on the hinge arm of the hatch, and has a locking piece, a positioning piece and a limiting piece, wherein the locking piece has a locking part locked with the locked part, and has Three blocking parts, the positioning part is arranged adjacent to the locking part, and has two protrusions arranged opposite to the three blocking parts, and the limiting part is arranged between the locking part and the positioning part for Limit the movement range of the relative position of the locking piece and the positioning piece, and use the three blocking parts of the locking piece, the two protrusions of the positioning piece and the limit piece to define at least two different relative positions of the locking piece relative to the positioning piece. Location.

Description

technical field [0001] The invention relates to the field of aircraft door mechanism design, in particular to an aircraft door gust lock device for preventing the aircraft door from shaking due to gusts of wind or other external forces. Background technique [0002] After the aircraft door is opened, the gust lock device can keep the aircraft door in a fixed position to prevent the aircraft door from shaking due to gusts of wind or other external forces. This gust lock device is generally suitable for outward opening doors, and the gust lock device can be installed near the fixed rotating shaft of the aircraft door to ensure that the aircraft door remains in the open position. [0003] In the past, the gust lock device was realized by using a boss and a groove-type limiting structure and a strut and a support-type limiting structure. For example, non-patent literature 1 "A General Aircraft Boarding Door "Gust Lock" (Xi'an Aircraft Design Institute of Aviation Industry Corpo...
