The beneficial effects of this application are: the fixing structure can be symmetrical, the position of the hinge hole can be at the left side, also can be at the right side, and is bilaterally symmetrical, so that the installation and the operation are convenient, and the limiting function of the two parts is utilized to play a good limiting role on dislocation movement of the process floor along the length direction of the ground rail. The application has adopted the two-part components of a whole that can function independently designs of ground rail mounting and floor mounting for the installation becomes very simple and convenient, only needs to assemble two parts respectively, then utilizes the slidable characteristic of ground rail mounting in the ground rail inslot, can accomplish stable safe connection fixed. Finally, after the installation is completed, the process floor can be opened and closed along the pin shaft in the structure, and the installation and inspection work of the lower part parts of the process floor is not hindered. The parts are connected by adopting the anti-drop structure, so that excessive materials are avoided, and the safety and reliability are realized; the installation method is extremely simple and convenient, and saves time and labor. Can be reformed according to different ground rail sizes, and further can be widely applied to development and mass production of various airplanes in the future, and has higher popularization value and economic benefit.
The application is described in further detail below in conjunction with the drawings of the embodiments.
