[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 realizing 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 case slide rail installation structure provided by 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 the back rail 20 are fixedly arranged on the cabin structure (not shown). Usually, the top rail 10 and the back rail 20 are arranged along the axis of the fuselage. The top rail 10 and the back rail 20 are provided with a slide groove extending along the length direction thereof, and the top rail 10 is provided with a plurality of top rail notches 11 in the length direction, and the back rail 20 is provided with a plurality of back rail notches 21 in the length direction and a mounting hole 22 located at the bottom of the slide groove.

[0048] The suitcase as a whole is composed of a plurality of suitcase bodies 50, and a pull rod assembly 51 is fixedly provided on both sides of each suitcase body 50, and 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 notch 11 of the top slide rail. 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 notch 21 of the back slide rail. The back slide rail 40 includes a latch 42, which passes through the mounting hole 22 and cooperates with a nut (not shown). When each suitcase body 50 slides to an 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 the present application is provided with an L-shaped outwardly expanded rib 12 on the upper side for installing the top slide rail fixing bracket. At the same time, the outwardly expanded 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 notch 11 and the back rail notch 21 provided on the top rail 10 and the back rail 20 are both square notches, and the size of the square notch can be set to 70mm×25mm, which can be adjusted according to actual conditions. The square notches are provided to 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 adapted to the slide groove and mounting seats 412 located on both sides of the root 411, and a groove adapted to the edge of the slide groove is provided between the root 411 and the mounting seat 412. Furthermore, a square hole for mounting the pin 43 is provided on the mounting seat 412, and the back slider body 41 can be fixedly connected to the vibration reduction assembly 52 through the pin 43. A square hole is provided in the middle of the back slider body 41 between the two mounting seats 412, and the latch 42 extends into the square hole and passes through the mounting hole 22 on the back slide rail 20 to fix the back slider body 41 to the back slide rail 20. The latch 42 and the pin 43 both have a terminal structure at one end and a columnar thread structure at the other end. They can be locked by the thread structure of the nut and the latch 42.

[0055] In the present application, the cross-sectional shape of the top slide rail 10 and the back slide rail 20 is the same, and the cross-sectional shape of the root of the top slider body 31 and the back slider body 41 is adapted to the cross-sectional shape of the slide groove, that is, the cross-sectional dimensions of each slider body in the top slider 30 and the back slider 40 are consistent. Furthermore, there is a gap between each slider body and the corresponding slide groove wall to prevent the slider and the slide rail from getting stuck.

[0056] The aircraft luggage case slide rail mounting structure provided in the present application can realize the adjustment and installation of luggage cases of different block sizes. At the same time, by designing structures such as the slide rail cross-section, the slider form and the slide rail notch, the installation efficiency, strength and overall effect of the luggage case can be effectively guaranteed, the installation interface with the structure is reduced, the weight is reduced, and the adjustment and efficient installation of the luggage case can be realized.

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