A high-stability bottom connection device for an airline dining car

Abstract

The invention provides a high-stability bottom connecting device of an aviation dining car, and relates to the technical field of aviation dining cars. The high-stability bottom connecting device of the aviation dining car comprises a floor, wherein a spacing strip is fixedly connected to the top of the floor through a spring, a limiting plate is fixedly installed at the top end of the spacing strip, a bent pipe is arranged in the floor, a first piston is in sliding connection with the interior of one side of the bent pipe, and a pressing rod is fixedly installed at the top end of the first piston. According to the high-stability bottom connecting device of the aviation dining car, limiting of the dining car is achieved, the dining car can stably move in the center of a cabin corridor, sothat when an aircraft is bumpy, the phenomenon that the dining car is prone to toppling is avoided, the safety in the use process of the dining car is improved, the spacing strip and the limiting plate can be re-trapped in the groove at the bottom of the floor, the walking obstacle of the passengers is avoided, the dining car can move left and right to avoid the passengers, and normal walking of the passengers is avoided.

Description

technical field [0001] The invention relates to the technical field of aviation dining cars, in particular to a high-stability bottom connection device for aviation dining cars. Background technique [0002] Airplane is one of the most important inventions of human beings. It subverts our concept of traditional travel methods and makes our travel more convenient and faster. Therefore, for long-distance travel distances, airplanes are often the best choice, and due to The one-way flight time of the aircraft is long, and the passengers need to have meals on the aircraft. At this time, the flight attendants are required to use the dining car in the cabin of the aircraft to provide meal services for the passengers. [0003] However, traditional dining carts are push-box structures equipped with rollers. During the delivery process, flight attendants are required to push the dining carts between the cabin corridors for delivery service. There will be shaking, so there will be a ...

Problems solved by technology

[0003] However, traditional dining carts are push-box structures equipped with rollers. During the delivery process, flight attendants are required to push the dining carts between the cabin corridors for delivery service. There will be shaking, so there will be a phenomenon of the dining car toppling over, which is easy to injure passengers. In order to ensure the stability of the dining car, some guide rails will be installed at the bottom of the cabin, but because the guide rails protrude upward, it is inconvenient for passengers to walk.
