A laterally positioned anti-slip mechanism for drawers in an aircraft cabin

Abstract

The invention relates to the technical field of aviation, in particular to a lateral positioning type anti-slip mechanism of an aviation cabin. The lateral positioning type anti-slip mechanism is composed of a cabinet body, a drawer, lateral transverse cavities, a locking rod, a middle cavity, a rotating rod, pin shafts, telescopic channels, a handle, a telescopic rod, a rotating disc, lateral vertical cavities, a force transmission block, a rod end shaft, an oblique-angled pit, a center shaft torsion spring, a rod center shaft, a rotating disc torsion spring and a rotating disc shaft. The rectangular middle cavity is formed in an outer lateral plate of the drawer, the two lateral transverse cavities are formed in a left lateral plate and a right lateral plate of the drawer respectively, each lateral transverse cavity is a horizontal strip-shaped space, the two lateral vertical cavities communicated with the corresponding lateral transverse cavities are arranged at one ends of the lateral transverse cavities respectively, and the lateral vertical cavities are communicated with the middle cavity through the horizontally-arranged telescopic channels. The drawer is locked through continuous torque and mutual blocking of a protrusion on the end portion of the locking rod and the oblique-angled pit of the cabinet body, and therefore the lateral positioning type anti-slip mechanism has high reliability and durability.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a laterally positioned anti-slip mechanism for drawers in an aircraft cabin. 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. Drawers for storing infrequently used items are arranged on the top of the combination cabinet. In order to facilitate removal, the combination of these drawers and the combination cabinet adopts a drawer structure. To fix the drawer, 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 be wound around The shaft spins. Normally, the baffle is rotated to the vertical direction to prevent the drawer from sliding; when the drawer needs to be accessed, the baffle is rotated to the horiz...

AI Technical Summary

Problems solved by technology

[0003] 1. Long-term repeated rotation of the retainer around the shaft will cause mutual wear between the two, and long-term wear will reduce the friction between the two, thereby reducing the stability of the retainer

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 drawer will slide out of the combination cabinet under its gravity and hit the cabin floor. Such an accident will cause damage to the cabin and the drawer on the one hand, and the other On the one hand, if the drawer hits the flight attendant or passenger, it will cause more serious injuries

[0004] 2. When the flight attendant opens the drawer and takes out the items, if the plane tilts, if the flight attendant is a little careless and fails to hold the handle of the drawer firmly, the drawer will still slide out of the cabinet and injure the flight attendant
