[0032] In an embodiment of the present application, the description is based on the seat rail 4 of the rear fuselage section. The positioning block at the bottom of the positioning plate 1 is used for positioning and docking with the seat rail 4 of the rear fuselage section.

The structure is simple and does not require a complex tooling structure, and can ensure that the step difference and clearance between the seat rail of the middle fuselage and the seat rail of the rear fuselage section meet the requirements.

[0033] In another embodiment of the present application, the description is based on the seat rail 5 of the middle fuselage. The positioning block at the bottom of the positioning plate 1 is used for positioning and docking with the seat rail 5 of the middle fuselage. The positioning plate 1 is provided with a pressing installation hole 8 and a positioning hole 9. The pressing component 2 is used to pass through the pressing installation hole 8 and fix it with the seat rail 5 of the middle fuselage, thereby realizing the docking of the positioning plate 1 and the seat rail 5 of the middle fuselage; the positioning pin 3 is used to pass through the positioning hole 9 to position the positioning plate 1 and the seat rail 4 of the rear fuselage section, so that both the seat rail 4 of the rear fuselage section and the seat rail 5 of the middle fuselage are in contact with the bottom of the positioning plate 1, and then the pressing component 2 passes through the pressing installation hole 8 and fixes it with the seat rail 4 of the rear fuselage section to be docked and positioned, ensuring that the seat rail 4 of the rear fuselage section and the seat rail 5 of the middle fuselage are positioned through the positioning plate 1. The structure is simple and does not require a complex tooling structure, and can ensure that the step difference and clearance between the seat rail of the middle fuselage and the seat rail of the rear fuselage section meet the requirements.

[0034] In a specific embodiment of the present application, as Figure 5 shown, the positioning block at the bottom of the positioning plate 1 is set according to the existing installation hole structure on the seat rail 4 of the rear fuselage section or the seat rail 5 of the middle fuselage to be docked and positioned. The present application takes the circular hole provided on the seat rail 5 of the middle fuselage as an example for illustration, as Figure 2 、 Figure 3 、 Figure 4As shown in the figure, correspondingly, a cylindrical positioning block 6 and a diamond-shaped positioning block 7 are arranged at the bottom of the positioning plate 1. The cylindrical positioning block 6 and the diamond-shaped positioning block 7 are respectively inserted into the circular holes on the middle fuselage seat rail 5. The purpose of the diamond-shaped block is to facilitate positioning and installation, ensuring the positioning accuracy of the position between the positioning plate 1 and the middle fuselage seat rail 5. After positioning the positioning plate 1 with the middle fuselage seat rail 5 as the reference, the positioning plate 1 and the middle fuselage seat rail 5 are pressed and fixed by the pressing component 2. Then, the rear fuselage seat rail 4 is positioned by the positioning pin 3. The positioning holes on the rear fuselage seat rail 4 and the positioning holes 9 on the positioning plate 1 are inserted and positioned through the positioning pin 3. Then, the rear fuselage seat rail 4 and the positioning plate 1 are pressed by the pressing component 2 again, thereby achieving the purpose of docking and positioning the rear fuselage seat rail 4 and the middle fuselage seat rail 5 through the positioning plate 1, ensuring that the step difference and clearance between the middle fuselage seat rail and the rear fuselage seat rail meet the requirements. Similarly, through the device structure of the present application, the front fuselage seat rail can be directly docked and installed with the middle fuselage seat rail.

[0035] In the specific implementation manner of the present application, to adapt to the different installation hole structures and dimensional structures on the front fuselage seat rail, the rear fuselage seat rail 4, and the middle fuselage seat rail 5, the positioning blocks at the bottom of the positioning plate 1 in the present application are detachably installed at the bottom of the positioning plate 1. For the front fuselage seat rail, the rear fuselage seat rail 4, and the middle fuselage seat rail 5 with the same hole pitch but different hole structures, by replacing the positioning block structures with the same hole structures as those on the front fuselage seat rail, the rear fuselage seat rail 4, and the middle fuselage seat rail 5, the versatility of the positioning plate 1 is increased, thereby improving the usability of the positioning plate 1.

[0036] Specifically, for the detachable installation of the positioning block, in the embodiment of the present application, the positioning block is specifically installed at the bottom of the positioning plate 1 by means of plugging, with a simple structure and convenient disassembly; or the positioning block is fixed at the bottom of the positioning plate 1 by means of threaded connection. By adopting the threaded connection method, the stability of the positioning block installation can be ensured, effectively preventing the risk of falling.

[0037] In the specific implementation manner of the present application, the pressing component 2 is used to quickly fasten the positioning plate 1 with the front fuselage seat rail, the rear fuselage seat rail 4, and the middle fuselage seat rail 5. Therefore, the pressing component 2 adopts a convenient fastening structure design. In the specific implementation manner of the present application, such as Figure 6As shown, the pressing component 2 includes a pressing nut 11, a pressing fixed block 14 and a pressing handle 10. The middle of the pressing fixed block 14 is a through-hole structure. The pressing nut 11 is hinged to the pressing handle 10 through a connecting rod 15. The connecting rod 15 passes through the through-hole structure of the pressing fixed block 14. A rotating groove for the rotation of the pressing handle 10 is provided at the upper end of the pressing fixed block 14. The hinge axis of the pressing handle 10 and the connecting rod 15 is the rotation axis of the pressing handle 10. The hinge axis of the pressing handle 10 and the connecting rod 15 is eccentrically arranged on the pressing handle 10. Rotating the pressing handle 10 can drive the connecting rod 15 to slide on the pressing fixed block 14. During use, pass the pressing nut 11 through the pressing installation hole 8 on the positioning plate 1 and set it at the bottom of the circular hole of the rear-section seat slide rail 4 or the middle-section seat slide rail 5 of the fuselage to be docked. Then adjust the position of the pressing nut 11. After being limited by the rear-section seat slide rail 4 or the middle-section seat slide rail 5 of the fuselage, at this time, the pressing fixed block 14 is located at the upper end of the positioning plate 1. Rotate the pressing handle 10, and the pressing handle 10 drives the pressing nut 11 to move upward through the connecting rod 15, so as to realize the pressing and fastening of the rear-section seat slide rail 4 or the middle-section seat slide rail 5 of the fuselage and the positioning plate 1. The structure of this application is simple and the installation is convenient. It can meet the docking requirements of different types of seat slide rails and has strong versatility.

[0038] Further, a compression spring is sleeved on the connecting rod 15. One end of the compression spring contacts the pressing fixed block 14, and the other end of the compression spring contacts the pressing nut 11. The purpose is to ensure that during the relaxation process, the pressing nut 11 can automatically rebound in place and prevent the pressing handle 10 connected to the connecting rod 15 from freely shaking, ensuring the stability of the part structure.

[0039] In another embodiment of this application, the pressing component 2 adopts a bolt-nut structure. The bolt-nut structure includes a bolt rod and a nut. The rod body of the bolt rod can pass through the pressing installation hole 8 of the positioning plate 1, and then the end of the bolt rod is opened at the bottom of the rear-section seat slide rail 4 or the middle-section seat slide rail 5 of the fuselage, and then the bolt rod is fastened with a nut, which can also realize the function of pressing and fastening the rear-section seat slide rail 4 or the middle-section seat slide rail 5 of the fuselage and the positioning plate 1; In the specific implementation manner of this application, the purpose of the pressing component 2 is to press and fasten the rear-section seat slide rail 4 or the middle-section seat slide rail 5 of the fuselage and the positioning plate 1. The two pressing component structures provided above in this application are only a result display in the specific implementation manner of this application.

[0040] In the specific implementation manner of this application, the pressing installation hole 8 on the positioning plate 1 is specifically a mother-and-son hole structure, such as Figure 5As shown, the parent-child hole structure specifically includes two large and small hole structures that are connected and communicate with each other. The compression nut 11 passes through the positioning plate 1 through the large hole structure, and then by adjusting the position of the compression nut 11, it is ensured that the compression nut 11 is positioned on the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage.

[0041] As Figure 5 , Figure 7 shown, in the specific embodiment of the present application, the positioning pin 3 is used to position the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage to be docked, preventing the occurrence of movement during the clamping process. Therefore, the positioning pin 3 corresponds to the positioning holes on the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage, and is consistent with the original installation positioning blocks on the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage; in this application, a circular docking hole structure is taken as an example for illustration. The positioning pin 3 includes a positioning pin column 13 and a positioning handle 12 fixed on the positioning pin column 13. The lower end of the positioning pin column 13 is a stepped shaft structure. The lower end of the positioning pin column 13 can pass through the positioning plate 1 and insert into the corresponding positioning holes on the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage, realizing the preliminary positioning with the positioning plate 1 during the docking installation of the seat slide rail 4 of the rear section of the fuselage and the seat slide rail 5 of the middle fuselage. After positioning the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage with the positioning pin 3, then the seat slide rail 4 of the rear section of the fuselage or the seat slide rail 5 of the middle fuselage and the positioning plate 1 are pressed tightly by the pressing assembly 2. The structure is simple, the installation is convenient, and the stepped shaft structure design on the positioning pin 3 can prevent the positioning pin 3 from being inserted too deep.

[0042] In the specific embodiment of the present application, the docking of the seat slide rail 5 of the middle fuselage and the seat slide rail 4 of the rear section of the fuselage is taken as an example for specific illustration. In this application, both the seat slide rail 5 of the middle fuselage and the seat slide rail 4 of the rear section of the fuselage can be used as the reference. In this embodiment, the seat slide rail 5 of the middle fuselage is used as the reference for illustration:

[0043] S1: Insert the cylindrical positioning block 6 and the diamond-shaped positioning block 7 on the fixing plate 1 into the circular holes on the seat slide rail 5 of the middle fuselage respectively, and then press and fix the fixing plate 1 and the seat slide rail 5 of the middle fuselage with the pressing assembly 2;

[0044] S2: Then adjust the seat slide rail 4 of the rear section of the fuselage so that the positioning pin 3 can be inserted into the positioning hole 9 on the fixing plate 1 and the positioning hole on the seat slide rail 4 of the rear section of the fuselage at the same time;

[0045] S3: Then press and fix the seat slide rail 4 of the rear section of the fuselage and the fixing plate 1 with the pressing assembly 2, and the docking and pressing work of the seat slide rail 5 of the middle fuselage, the seat slide rail 4 of the rear section of the fuselage and the fixing plate 1 can be completed;

[0046] S4: Finally, connect the mid-fuselage seat slide rail 5 and the rear-fuselage seat slide rail 4 to complete the docking of the mid-fuselage seat slide rail 5 and the rear-fuselage seat slide rail 4. Similarly, dock the mid-fuselage seat slide rail 5 and the front-fuselage seat slide rail.

[0047] This application can meet the docking requirements of seat slide rails of different models by replacing the cylindrical positioning block 6 and the diamond-shaped positioning block 7 on the fixing plate 1 and the positioning pins 3 of different shapes. It has strong versatility, simple structure and convenient use. It solves the problems of step difference and clearance out-of-tolerance at the docking of the aircraft fuselage seat slide rails, and can effectively improve the docking efficiency and quality of the aircraft seat slide rails.
