[0044] In order to make the purpose, technical solutions and advantages of the implementation of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below in conjunction with the drawings in the embodiments of this application.

[0045] The present application provides an aircraft luggage case slide rail mounting structure for achieving adjustable installation of luggage cases of different block sizes. At the same time, by designing the slide rail cross-section, slider form, slide rail notch and other structures, the installation efficiency, strength and overall effect of the luggage case are effectively guaranteed, the installation interface with the structure is reduced, and the weight is reduced.

[0046] like Figures 1 to 4 As shown, the aircraft luggage box slide rail installation structure provided in the present application includes: a top slide rail 10 , a back slide rail 20 , a top slider 30 and a back slider 40 .

[0047] The top rail 10 and back rail 20 are fixed to the cabin structure (not shown). Typically, they are arranged along the fuselage axis. Each rail has a slot extending along its length. The top rail 10 has a plurality of top rail notches 11 along its length, while the back rail 20 has a plurality of back rail notches 21 along its length, as well as mounting holes 22 at the bottom of the slot.

[0048] The suitcase as a whole is composed of a multi-section suitcase body 50, and a pull rod assembly 51 is fixedly provided on both sides of each section of the suitcase body 50. Two shock-absorbing assemblies 52 are fixedly provided on the back of the suitcase body 50. After the pull rod assembly 51 is connected to the top slider 30, it slides into the slide groove of the top slide rail 10 through the top slide rail notch 11. After the shock-absorbing assembly 52 is connected to the back slider 40, it slides into the slide groove of the back slide rail 20 through the back slide rail notch 21. The back slider 40 includes a pin 42, which passes through the mounting hole 22 and cooperates with a nut (not shown). When each section of the suitcase body 50 slides to the appropriate position through the top slide rail 10 and the back slide rail 20, the suitcase is locked in the two slide rails.

[0049] like Figure 5 As shown, the top slide rail 10 in this application is provided with an L-shaped outward-expanding rib 12 on the upper side for installing the top slide rail fixing bracket. At the same time, the outward-expanding rib 12 ensures the overall rigidity of the top slide rail 10 and reduces the number and interface relationship of the top slide rail fixing bracket.

[0050] like Figure 6 As shown, the back rail 20 in the present application is provided with an outward expansion wall 23 for installing the back rail fixing bracket. At the same time, the outward expansion wall 23 ensures the overall rigidity of the back rail and reduces the number and interface relationship of the rail fixing bracket.

[0051] In the preferred embodiment of the present application, the top rail notches 11 and the back rail notches 21 provided on the top rail 10 and the back rail 20 are both square notches, and the dimensions of the square notches can be set to 70 mm x 25 mm, which can be adjusted according to actual conditions. The square notches facilitate the installation of the top slider 30 and the back slider 40.

[0052] Furthermore, the mounting holes 22 provided on the back slide rail 20 in the present application are pairs of circular holes, the size of which can be set to circular holes with a diameter of 10 mm, and the number, spacing and size of which can be adjusted according to actual conditions. The pairs of circular holes can facilitate the connection between the back slider 40 and the back slide rail 20.

[0053] like Figure 7 As shown, the top slider 30 in the present application includes a top slider body 31 and a top slider stud 32. The top slider stud 32 is located at both ends of the top slider body 31. The top slider stud 32 is a columnar external thread structure. The top slider 30 can be installed and connected with the pull rod assembly 51 through the top slider stud 32.

[0054] like Figure 8 As shown, the back slider 40 includes a back slider body 41, a latch 42, and a pin 43. The back slider body 41 includes a root 411 that fits into the slide groove and mounting seats 412 located on either side of the root 411. A groove that fits into the edge of the slide groove is defined between the root 411 and the mounting seats 412. Furthermore, a square hole is provided on the mounting seats 412 for mounting the pin 43, which securely connects the back slider body 41 to the vibration damping assembly 52. ​​A square hole is provided in the middle of the back slider body 41, between the two mounting seats 412. The latch 42 extends into this square hole and passes through the mounting hole 22 on the back slide rail 20, securing the back slider body 41 to the back slide rail 20. Both the latch 42 and the pin 43 have a terminal structure at one end and a cylindrical threaded structure at the other end. They can be locked together using a nut and the threaded structure of the latch 42.

[0055] In this application, the cross-sectional shape of the top and back rails 10 and 20 is identical. The cross-sectional area at the base of the top and back slider bodies 31 and 41 matches this cross-sectional shape. That is, the cross-sectional dimensions of the slider bodies of the top and back sliders 30 and 40 are identical. Furthermore, a gap exists between each slider body and the corresponding groove wall to prevent the slider and rail from becoming stuck.

[0056] The aircraft luggage case slide rail mounting structure provided in this application can realize the adjustment and installation of luggage cases with different block sizes. At the same time, by designing the slide rail cross-section, slider form, slide rail notch and other structures, it can effectively ensure the installation efficiency, strength and overall effect of the luggage case, reduce the installation interface with the structure, reduce the weight, and realize the adjustment and efficient installation of the luggage case.

[0057] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
