[0032] Please refer to figure 1 As shown, the aircraft door cover lock 100 provided in this embodiment is applied to locking or opening the maintenance door of an aircraft. In the aircraft flap lock 100 provided in this embodiment, the locking key 130 moves in a straight line, and the movable space is small, so it has wider applicability.

[0033] The aircraft flap lock 100 provided by this embodiment includes a housing 110, a lock key 130 and a transmission assembly 150. A slide rail 111 is arranged in the housing 110, and the lock key 130 is slidably matched with the slide rail 111. The transmission assembly 150 is respectively connected to the housing The body 110 and the lock key 130 are rotatably connected, and are used to rotate relative to the housing 110 under the action of an external force, and push and pull the lock key 130 during the rotation to drive the lock key 130 to slide along the slide rail 111 and extend or retract the housing 110. In practical applicatio...

Abstract

The invention discloses an access cover lock for an aircraft and the aircraft, and relates to the technical field of aircrafts. The access cover lock for the aircraft comprises a housing, a lock key and a drive assembly; the housing is provided with a sliding rail; the lock key and the sliding rail are in sliding fit; and the drive assembly is rotatably connected with the housing and the lock key,and is used for rotating relative to the housing under the action of an external force so as to drive the lock key to slide along the sliding rail and extend out of or draw back to the housing. The access cover lock for the aircraft has the beneficial effects that movement space for the lock key is relatively small, and applicability is wider.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to an aircraft flap lock and the aircraft. Background technique [0002] The flap lock is used for the locking and opening of the maintenance flap of the aircraft. The existing flap lock generally adopts a swing type lock key, and the flap is locked or opened by rotating the lock key (usually 90 degrees). [0003] The lock key of this type of flap lock has a large space for movement. For some aircrafts with small size and limited space at the flap, this type of flap lock will no longer be suitable. Contents of the invention [0004] The object of the present invention is to provide an aircraft flap lock, which can reduce the movable space of the locking key. [0005] Another object of the present invention is to provide an aircraft, which can reduce the movable space of the locking key. [0006] The invention provides a technical solution: [0007] An aircraft flap lock, compr...
