[0016] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0017] Embodiment 1
[0018] like Figure 1 As shown, an embodiment of the present invention provides an arresting structure for bearing heading loads, including a connecting boss for socketing an aircraft cabin section, a web 1, an oblique rib plate 3, and a triangular rib plate 2. A socket surface 5 is provided on the inner circumferential wall of the connecting boss away from the socket end of the aircraft cabin section, and two oblique rib plates 3 and a triangular rib plate 2 are provided on the inner wall of the socket surface 5. An ear piece 4 is connected to the back side of each of the oblique rib plates 3, and one end of each of the ear pieces 4 away from the connecting side of the oblique rib plate 3 extends outward in an arc shape and is connected to the inner wall of the socket surface 5. A web 1 is provided between adjacent sides of each of the oblique rib plates 3, and a connecting ear piece 6 is provided between the side of the web 1 away from the socket end of the connecting boss and the aircraft cabin section and the inner circumferential wall of the socket surface 5. A triangular rib plate 2 is penetrated through the middle part of the web 1 and the connecting ear piece 6 along the axial direction of the connecting boss, and a pin hole 7 is penetrated through the middle part of the web 1 along the radial direction of the connecting boss.
[0019] By designing a socket surface 5 on the connecting boss and a web 1 on the socket surface 5, the section coefficient is increased and the structural stress is reduced; by designing a triangular rib plate 2 on the web 1, the local strength / rigidity is improved and the structural stress is reduced; by designing an inclined rib plate 3 on the web 1, the overall strength / rigidity of the boss is improved and the structural stress is reduced. The overall coordination between the various components can effectively improve the ability of the structure to withstand the heading arresting load and its additional bending moment.
[0020] Furthermore, four assembly holes for assembling with the slider are opened on the web 1, and one end of the connecting boss is socketed with the aircraft cabin section. The four assembly holes on the web 1 can withstand normal loads, and the pins can withstand heading loads. The slider connection is achieved through the four assembly holes on the web 1 combined with the pins on the inclined rib plate 3, and then the assembly with the guide frame is achieved through the slider.
[0021] Furthermore, the triangular rib plate 2 is arranged on the inner wall of the sleeve surface 5, with one end flush with the edge of the sleeve surface 5 and the other end connected to the mounting hole on the inner wall of the connecting boss, thereby optimizing the overall layout and improving the ability of the overall structure to withstand the heading arresting load and its additional bending moment.
[0022] Furthermore, the sleeve surface 5 on the connecting boss and the web 1, the oblique rib plate 3, the triangular rib plate 2, the ear piece 4, and the connecting ear piece 6 on the sleeve surface 5 are all integrally formed to ensure the ability of the overall structure to withstand the heading arresting load and its additional bending moment.
[0023] Furthermore, the diameter of the pin hole 7 is 10 mm-14 mm, which improves the shear bearing capacity of the pin and the anti-extrusion capacity of the pin hole 7 and reduces structural stress.
[0024] Furthermore, the thickness of the sleeve surface 5 is 6 mm to 8 mm, which improves the bending resistance and reduces the structural stress.
[0025] Furthermore, the thickness of the connecting ear piece 6 is 14 mm-16 mm, which improves the bending resistance and reduces the structural stress.
[0026] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
