[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] like Figure 1 , Figure 2 The illustrated airborne turntable mounting mechanism includes a screw jack 1, a connecting rod 2, a coupling 3, a base 4, a universal brake wheel 5, and a mounting plate 6. The screw jack 1 is located on top of the base 4. The connecting rod 2 has couplings 3 at both ends, which cooperate with the output shaft of the screw jack 1. The universal brake wheel 5 is fixed below the base 4. The mounting plate 6 has a turntable mounting surface 602 with a connection hole between the turntable and the anti-rotation flange 101 of the screw jack 1. The connecting rod 2 and the coupling 3 enable the screw jack 1 to rotate synchronously in pairs. By rotating the handwheel 102 of the screw jack 1, the height of the anti-rotation flange 101 can be adjusted to drive the mounting plate 6 to move up and down.

[0017] In this utility model, the mounting surface 603 of the mounting plate 6 is provided with reinforcing C-shaped aluminum 601. First, the C-shaped aluminum 601 is fixed to the mounting surface 603 with screws, then the joint of the C-shaped aluminum 601 is laser welded, and finally welded to the mounting plate 6 to form a whole.

[0018] In this invention, the universal brake wheel 5 is fixed below the base 4, which enables the mechanism to easily turn and lock in position.

[0019] The above description is merely a preferred embodiment of this utility model and does not imply its uniqueness or limitation. Those skilled in the art should understand that various changes or equivalent substitutions made to this utility model without departing from its scope are all within the protection scope of this utility model.
