[0026] Figure 1 This is a schematic diagram of the aircraft ceiling connection mechanism of the present invention. Figure 1 An embodiment of the present invention provides an aircraft ceiling connection mechanism, comprising: a connection bracket 1, a buffer rope 3, and two interior panels 7 parallel to each other on the aircraft upper wall panel.

[0027] The maintenance cover is located between the two interior panels 7;

[0028] The connecting bracket 1 is arranged between the left interior trim panel 7 and the maintenance cover;

[0029] One end of the buffer rope 3 is connected to the maintenance cover, and the other end is connected to the right interior trim panel 7.

[0030] When the maintenance cover is opened, when the maintenance cover is opened to a preset angle under the action of the connecting bracket 1, the other end of the buffer rope 3 fixed on the right interior panel 7 is fixed on the maintenance cover to stop the maintenance cover from falling.
