When the antenna body 1 is located outside the protection cavity 211, the indoor omnidirectional antenna is in a normal use state, and when the antenna body 1 is located in the protection cavity 211, the indoor omnidirectional antenna is in a fire protection state. Specifically, the flap 23 is disposed in a circular plate shape, and the diameter of the flap 23 is slightly smaller than the inner diameter of the protection cavity 211 so as to be able to rotate smoothly in the protection cavity 211. The outer circular surface of the turning plate 23 is provided with a rotating shaft 231, the axis of the rotating shaft 231 is parallel to the plate surface of the turning plate 23, the axis of the rotating shaft 231 penetrates through the axis of the turning plate 23 and is perpendicular to the axis of the turning plate 23, and meanwhile, the axis of the rotating shaft 231 penetrates through the axis of the heat insulation shell 21 and is perpendicular to the axis of the heat insulation shell 21.
