Large seaplane control surface suspension structure

The invention provides a seaplane control surface suspension structure. The control surface suspension structure comprises a fixed suspension joint (3), a suspension support arm (4), a transition joint (5), control surface butt joints (6) and a knuckle bearing (7). Each control surface butt joint (6) is fixedly arranged on a control surface (1) of the seaplane; the fixed suspension joint (3) is fixedly connected to a stabilizing surface (2) of the large seaplane and is rotationally connected with the control surface (1) through one control surface butt joint (6); the first end of the suspension support arm (4) is fixedly connected to the stabilizing surface (2) of the large seaplane, the second end of the suspension support arm (4) is connected with the first end of the transition joint (5) through a knuckle bearing (7), and the second end of the transition joint (5) is connected with one control surface butt joint (6) through the knuckle bearing (7).
