Gravity type aviation cabin anti-oblique-slip high box locking mechanism

Abstract

The invention relates to the technical field of aviation, in particular to a gravity type aviation cabin anti-oblique-slip high box locking mechanism. The mechanism consists of a cabinet body, a high box, rotating shafts, a magnet sheets, an iron blocks, a housings, a drawer bottom board, separation sheets and a handle, wherein the cabinet body and the drawer bottom board form a drawer cavity; the high box is positioned in the drawer cavity; the outer end face of the drawer bottom board is provided with a pair of rotating shafts; each rotating shaft penetrates through a through hole of a separation sheet and is in rotary movable fit relation with the separation sheet; the distance from the rotating shaft of each separation sheet to the axis of the corresponding iron block is equal to the distance from the rotating shaft to the axis of the corresponding magnet sheet outside the rotating shaft; and the width of the separation sheet and the external diameter of the housing are both less than the thickness of the drawer bottom board. The keeping of a locking state of the high box by the separation sheet is that the high box is locked by keeping the separation sheets in a vertical state under the gravity action of the iron blocks; and the mechanism has higher reliability and durability.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a gravity-type aviation cabin anti-slip high box locking mechanism. Background technique [0002] The side of the emergency escape passage of the existing civil aviation airliner is provided with a metal combination cabinet integrating a dining car, a locker and a filing cabinet. High boxes for storing infrequently used items are arranged on the top of the combination cabinet. In order to facilitate removal, the combination of these high boxes and combination cabinets adopts a drawer structure. In order to fix the high box, a block with a rotating shaft at one end is arranged on the outer edge of the combination cabinet. The shaft is fixed to the combination cabinet, and the block Can rotate around the axis. Normally, the baffle is rotated to the vertical direction to prevent the high box from sliding; when the high box needs to be taken, the baffle is rotated to the horizont...

AI Technical Summary

Problems solved by technology

[0003] Long-term repeated rotation of the baffle around the shaft will cause the two to wear each other, and long-term wear will reduce the friction between the two, thereby reducing the stability of the baffle

During the take-off process of the aircraft, there will be relatively severe high-frequency vibrations. Under this vibration, the baffle will rotate around the axis of rotation to the horizontal direction under the action of its own gravity, and the whole fuselage of the aircraft has a large inclination angle during the take-off process. , once the baffle itself rotates to the horizontal direction, its blocking effect disappears, and the high box will slide out of the combination cabinet under its gravity and hit the ground of the engine room. Such an accident will cause damage to the engine room and the high box on the one hand. On the other hand, if the high box hits the flight attendant or passenger, it will cause more serious injuries.
