[0006] The installation method comprises the following steps:

[0007] S1. The hook card of the decorative panel is connected to the hook groove at the lower end of the guide rail;

[0008] S2. Move the decorative panel as a whole along the length direction of the guide rail so that the latch is aligned with the retaining spring seat on the structural plate;

[0009] S3. Push the decorative plate upward so that the latch is inserted into the spring seat to complete the plug-in fixation;

[0010] S4. Install a rubber strip in the hook groove to fix the hook through the rubber strip to prevent the decorative panel from sliding and shaking.

[0011] The present invention also has the following preferred design:

[0012] The top of the plug of the present invention is a spherical plug, and the bottom of the plug is embedded and fixed inside the connecting block to form a whole, so as to facilitate blind plugging and alignment.

[0013] The retaining spring seat of the present invention is triangular in shape, and the spring sheets on both sides of the retaining spring seat are bent relative to each other to form an elastic socket.

[0014] The retaining spring seat of the present invention is embedded and fixed inside the structural plate to form a whole.

[0015] In the present invention, a cushion block is arranged between the hook and the decorative plate, the cushion block is bonded to the decorative plate, and the hook is fixedly connected to the cushion block by bolts.

[0016] The connection block of the present invention is bonded to the decorative plate.

[0017] The present invention has the following beneficial effects:

[0018] The decorative panel of the present invention is connected to the hangers on the ceiling and the side wall respectively by using quick-release pins and hooks, and the installation operation is not limited by the narrow space. The aircraft cabin decorative panel can be quickly installed and disassembled without any tools, which improves the work efficiency of component installation and disassembly and facilitates later repair and maintenance.
