Abstract

The invention discloses an air pipe vehicle interlocking device. The air pipe vehicle interlocking device comprises an upper cover plate and a lower cover plate, wherein the upper cover plate and thelower cover plate are connected through an elastic part and a limiting device; the limiting device comprises a limiting part and a limiting slot; the limiting part is arranged in the limiting slot, and can move up and down relative to the limiting slot; and a micro switch is arranged between the upper cover plate and the lower cover plate. The air pipe vehicle interlocking device has the characteristics of being simple in operation, strong in applicability and the like. The air pipe vehicle interlocking device is simple in structure, is strong in operability, can avoid the problem that damageson an airplane are caused by staff misoperation while an air pipe is in a connecting state, and improves gas supply safety of a ground air-conditioning unit of the airplane.

Description

technical field [0001] The invention relates to the technical field of aircraft ground air-conditioning units, in particular to an air duct trolley interlocking device. Background technique [0002] The aircraft ground air conditioning unit is a special air conditioning equipment that provides filtered, pressurized, dehumidified and cooled (or heated) fresh air to the aircraft cabin that is parked on the ground. As an important airport ground support equipment, the special air conditioner for the aircraft ground can completely replace the aircraft powered by aviation fuel when the aircraft is on the ground (pre-flight preparation, post-flight inspection, etc.) The built-in APU air-conditioning system provides treated clean air to the cabin, greatly reducing aviation fuel costs and reducing pollution to the airport environment. [0003] In the prior art, it is often necessary to use an air duct to connect the air outlet of the aircraft ground air conditioner with the air inl...
