Folding mosquito net frame

The utility model provides a folding mosquito net frame which comprises a support frame, and the support frame at least comprises a vertical support rod; the folding frame is used for hanging a mosquito net, is rotationally connected with the support frame and is opened and closed around a rotary connection point relative to the vertical support rod; and the limiting mechanism is movably connected with the vertical supporting rod and the folding frame, controls the folding frame to be opened and closed and positions the opening and closing angle of the folding frame. By arranging the limiting mechanism with one end slidably hinged to the vertical supporting rod and the other end rotatably connected with the swing rod, vertical movement of the second hinge unit on the vertical supporting rod is converted into opening and closing of the folding frame, and the rotating plane of the swing rod and the vertical supporting frame are staggered, so that the folding frame cannot interfere with the vertical supporting f
