The invention relates to a simple air guide net, which is characterized in that a lower framework is arranged at the front end of a skylight track seat, a piece of screen cloth is connected between the front end of an upper framework and the framework of the lower framework in a pulling manner, and two side legs at the rear end of the upper framework are respectively connected to two sides of theskylight track seat through two mounting seats. The simple air guide net is characterized in that a pivoting seat is mounted at the rear part of the mounting seat; the tail end of a side foot at the rear end of the upper framework is connected into the pulling waist groove in a penetrating mode through a pivot pin and can be in a guiding sliding state along the pulling waist groove, a spring limiting bayonet for limiting the front side and the rear side is formed in the middle of the installation base, a spring foot bayonet is formed in the front portion of the installation base, and a torsional spring is connected with the upper framework and the installation base. The torsional spring comprises a middle elastic part, an upper spring foot and a lower spring foot, the middle elastic part is arranged in the spring limiting bayonet, the upper spring foot is connected with a drag hook, the drag hook is connected to the middle of the upper framework in a penetrating mode, and the lower spring foot is arranged in the spring foot bayonet. The assembly is compact, stable and firm in structure and free of jamming and abnormal sound in elastic expansion and contraction.
