Description

TECHNICAL FIELD

[0001] The application relates to a positioning method for installing an aircraft passenger cabin decorative plate. BACKGROUND

[0002] An aircraft passenger cabin is a place for passengers to rest, work and entertain. The main purposes of an aircraft passenger cabin decorative plate are to decorate the cabin, ensure the safety of the cabin and reduce noise, provide a good environment for passengers and improve the experience.

[0003] A commonly used method for installing an aircraft passenger cabin decorative plate is as follows: positioning is performed by using a positioning pin, and then a mushroom buckle is used for fixation. The mushroom buckle is a quick and safe structure that can be opened and fixed, and can replace nuts / bolts, buckles, pins, nails, zippers and welding. For example, a 3M mushroom buckle is composed of two plastic backing strips, and the backing strips have mushroom-shaped plastic protrusions (mushroom heads). Each square inch has different numbers of mushroom heads, such as 170, 250 and 400. The higher the number, the greater the closing strength. The back of the mushroom head can be provided with different back glue or no back glue according to needs. When the two pieces of the mushroom buckle are pressed together, the mushroom heads will be locked with each other and will make a cracking sound. If necessary, the mushroom buckle can be opened and can be used repeatedly 1000 times.

[0004] This assembly method requires that the positioning pin and the positioning pin support be accurately matched in position. When the assembly precision is insufficient, the positioning pin is often misaligned, which causes the decorative plate to not be guaranteed to be vertical and horizontal. This affects the aesthetic appearance of the interior decoration of the cabin. SUMMARY
