Anti-misoperation device for aircraft passenger cabin door

Abstract

The invention relates to an anti-misoperation device for aircraft passenger cabin doors. The anti-misoperation device for the aircraft passenger cabin door includes a guide groove, a rocker, a torsion spring, a hook, a spline shaft, a rocker bushing and a roller; wherein the roller is rigidly connected to one end of the rocker, And can move in the guide groove close to the inner wall of the guide groove; one end of the torsion spring acts on the frame of the first cabin door, and the other end of the torsion spring acts on the hook; the spline shaft is rigidly connected to the other end of the rocker, The hook is rigidly connected to the spline shaft so that the rocker, the spline shaft and the hook can rotate coaxially; the rocker bushing is installed on the latch shaft of the aircraft passenger door lift system and is rigidly connected The latch shaft rotates coaxially. The anti-misoperation device for the aircraft passenger cabin door of the present invention can have the following beneficial technical effects: the structure is relatively simple, and it can effectively prevent the cabin door from being closed by wrong operation of the aircraft personnel in the open state.

Description

technical field [0001] The invention relates to an anti-misoperation device for aircraft passenger cabin doors. Background technique [0002] The anti-misoperation device that prevents the personnel on the aircraft from closing the passenger compartment door by mistake is applied to the passenger compartment door of the aircraft. EASA 783d(8) states that a door that would be dangerous if left open must have means to prevent the latch from moving to the latched position, unless it can be shown that the open door would be apparent prior to flight. [0003] In order to comply with the provisions of this article, a certain model has designed an anti-misoperation device for the passenger cabin door of the aircraft. The anti-misoperation device directly acts on the handle mechanism and locks the handle when the door is fully opened, which meets the EASA 783d(8) article. Require. However, the anti-misoperation device has a large volume, a large number of parts, a high complexity,...
