The spoiler is not only to increase the gradient of the descent, the spoiler is usually used as the hinged panel or flap on the rear surface of the wing to reduce the lift of the aircraft. They are used for roll control during flight to increase the descent rate without increasing the airspeed, and are used to reduce the lift and increase the resistance during landing to slow down the aircraft. The aircraft spoiler is usually arranged on the upper surface of the wing, and the air flow on the upper surface of the wing is adjusted by opening and closing the aircraft spoiler. The aircraft spoiler basically adopts a single-point control and a multi-point suspension driving mode. The control joint is arranged at the front of the beam plane, and when the actuator is arranged, in order to ensure a sufficient force arm, the control point is usually arranged below the spoiler airfoil. The existing connection mode at the control point is that a connecting piece is arranged at the control point, the connecting piece is integrally arranged, and during installation, the driving end of the aircraft driving rod is arranged at the other end of the connecting piece, and then the two are fixed by penetrating the bolt along the extension direction of the spoiler. For the aircraft with a narrow space at the rear edge of the wing, the installation is difficult. SUMMARY

[0003] Therefore, the present application provides a spoiler control joint to solve the problem that the connecting piece at the control point is integrally arranged in the prior art, which causes the bolt to be transversely penetrated between the two during installation, and for the aircraft with a narrow space at the rear edge of the wing, the installation is difficult.

[0034] Please see Figures 1-4 This utility model provides an aircraft spoiler control connector, including a first connector 3 embedded in the aircraft spoiler and a second connector 6 connected to the drive end of the aircraft drive stick.

[0035] The first connector 3 and the second connector 6 are plate-shaped structures, and the first connector 3 and the second connector 6 are detachably connected by a first connecting component or a second connecting component.

[0036] The first connecting component includes guide rails and slide grooves 4 that are spaced apart along the length of the spoiler, wherein the guide rails and slide grooves 4 are positioned correspondingly.

[0037] The second connecting assembly includes a connecting post 8 and a connecting hole 1 located at the ends of the guide rail and the slide 4, respectively, wherein the guide rail is a dovetail-shaped guide rail.

[0038] The second connecting body 6 has a guide rail on the side facing the first connecting body 3. The guide rail matches the length, size, and shape of the slide groove 4 and is fixedly connected to the second connecting body 6. A connecting post 8 is provided on the second connecting body 6. The connecting post 8 is movably connected to the second connecting body 6 and moves along the thickness direction of the second connecting body 6. The movable connection between the connecting post 8 and the second connecting body 6 is achieved through a guide hole. Specifically, the second connecting body 6 has a guide hole that extends through it along the thickness direction. The connecting post 8 is located inside the guide hole and moves along the depth of the guide hole.

[0039] One end of the connecting post 8 faces the first connecting body 3, and the other end of the connecting post 8 is located outside the side of the second connecting body 6 facing away from the first connecting body 3. One or two limiting rods 9 are provided outside the end of the connecting post 8 facing the first connecting body 3. One end of the limiting rod 9 is fixedly connected to the connecting post 8, and the other end of the limiting rod 9 is set outward along the radial direction of the connecting post 8.

[0040] In order to avoid interference of the connecting column 8 with the first connecting body 3 and the second connecting body 6 during installation, this application provides a through groove 2 in the guide hole along the hole depth direction. The through groove 2 communicates with the guide hole. The cross section (i.e. the outer dimension) of the through groove 2 is larger than the overall outline of the limiting rod 9. The number and position of the through groove 2 correspond to the position and number of the limiting rod 9.

[0041] In order to prevent the connecting column from falling off from the end opposite to the first connecting body 3, in this application, the end of the connecting column 8 located outside the side of the second connecting body 6 opposite to the first connecting body 3 extends outward along the radial direction of the connecting column 8 with a limiting part 5. The cross-section of the limiting part 5 is larger than the cross-section of the through groove 2 and the guide hole.

[0042] In order to prevent the connecting post 8 from falling off from the end facing the first connecting body 3, in one embodiment of this application, a spring 10 is provided between the guide hole and the connecting post 8. One end of the spring 10 is connected to the bottom of the limiting part 5, and the other end of the spring 10 is connected to the inner wall of the end of the guide hole facing the first connecting body 3.

[0043] The second connector 6 has a connecting lug 7 on the side opposite to the first connector. The drive end of the aircraft drive stick is connected to the connecting lug 7 by bolts. The connecting lug 7 and the second connector 6 are integrally formed.

[0044] The first connector 3 is embedded in the aircraft spoiler. A groove 4 is provided on the side of the first connector 3 facing away from the aircraft spoiler. A connecting hole 1 is provided through the first connector 3 along its thickness.

[0045] The chute 4 is provided along the extension direction of the first connecting body 3 (i.e., the direction perpendicular to the spoiler), and at least two chute 4 are provided at intervals.

[0046] The connecting hole 1 is located at the end of the slide groove 4, between the two slide grooves 4, and there are one or two of them. The connecting hole 1 has a through groove 2 along the depth direction of the hole. The through groove 2 communicates with the connecting hole 1. The position and shape of the through groove 2 of the connecting hole 1 and the through groove 2 of the guide hole correspond to each other, and the number of them corresponds to the number of the limit. The diameter of the connecting hole 1 and the guide hole is slightly larger than the outer diameter of the connecting post 8.

[0047] A circular groove 12 is provided on the side of the connecting hole 1 facing the spoiler. The thickness of the circular groove 12 is slightly less than the thickness of the limiting rod 9. The maximum outer diameter of the circular groove 12 is greater than the sum of the lengths of the two through slots 2 and the diameter of the connecting post. A limiting groove 11 matching the shape and size of the limiting rod 9 is provided inside the circular groove 12. The size of the limiting groove 11 is slightly larger than the axial contour of the limiting rod 9, so that the limiting rod 9 can be placed in the limiting groove 11. One end of the limiting groove 11 communicates with the connecting hole 1, and the other end of the limiting groove 11 faces outward away from the connecting hole 1.

[0048] The limiting groove 11 is set perpendicularly to the through groove 2. Specifically, the through groove 2 of the connecting hole 1 and the through groove 2 of the guide hole are both set on the same side as the slide 4, and the center line of the limiting groove 11 coincides with the center line connecting the two slide 4.

[0049] During installation, firstly, the drive end of the aircraft's drive stick is bolted to the connecting lug 7; then, the limiting part 5 is pulled to pull the entire connecting post 8 toward the side with the connecting lug 7. At this time, the limiting rod 9 is located in the through groove 2 of the guide hole and slides along the through groove 2 of the guide hole; next, the guide rail of the second connecting body 6 is aligned with the slide groove 4 of the first connecting body 3 and slid along the slide groove 4 until the connecting post 8 is aligned with the corresponding connecting hole 1. At this time, the hand is released and the limiting rod 9 slides toward the first connecting body 3 along the through groove 2 of the guide hole and the through groove 2 of the connecting hole 1 in sequence. When it slides to the bottom of the through groove 2 of the connecting hole 1, it is rotated 90° so that the limiting rod 9 is located in the limiting groove 11.
