A New Type of Aircraft Guard Plate Interconnection Mechanism

Abstract

The invention relates to a mechanism for connecting and disconnecting an airplane protection plate from a protection plate and belongs to the field of airplane structure design. A novel airplane protection plate is used for connecting and disconnecting the airplane protection plate from the protection plate and mainly consists of a connector, a rocker arm with a locking hook, a shell, a rocker armwith a pressing key, a spring I and a spring II, wherein one end of the connector is rotationally connected with a rotation axis of the protection plate; the other end of the connector is connected with the piston rod of a protection plate release and withdrawing action cylinder; the rocker arm with the locking hook is provided with a connecting part I which is rotationally connected with the shell, a clamping part I which is clamped with the connector, and a clamping part III which is clamped with the rocker arm with the pressing key; the clamping part I and the clamping part II are arrangedon two sides of the connecting part I; the shell is fixedly connected with a protection plate sheath; the outer surface of the protection plate shell is covered by the protection plate sheath; the rocker arm with the pressing key is provided with a connecting part II which is rotationally connected with the shell, a limiting groove clamped with the clamping part II, and a pressing key which penetrates through the through hole in the protection plate sheath and is parallel to the outer surface of the protection plate sheath. The novel airplane protection plate has the advantages that the structure is simple and reliable, airplane protection plates can be rapidly opened and closed, and the maintenance properties of an airplane can be improved.

Description

technical field [0001] The invention relates to a connection and disconnection mechanism between an aircraft guard plate and a guard plate retractable actuator, belonging to the field of aircraft structure design. Background technique [0002] In the aircraft landing gear system, the landing gear guards mainly include pillar guards, wheel guards, etc., and their main function is to ensure the aerodynamic shape of the aircraft. There are usually two ways to open the guard plate, one is to directly control the opening or closing of the guard plate by retracting and retracting the actuator. The other is the follow-up type, that is, the guard plate is connected with the landing gear or the retractable cylinder of the landing gear through the pull rod, and opens or closes with the retracting and retracting of the landing gear. At present, the vast majority of aircraft wheel guards are opened or closed by retracting and retracting the actuator. At the same time, due to the overal...

Problems solved by technology

Due to the relatively small space in the wheel well of the landing gear, the range of movement of the hand is greatly restricted during the disassembly and assembly of the bolts, so the disassembly and maintenance process is very laborious
