The rotating block 6 forms a 360° rotation on the connecting shaft 5. When the insect-proof net main body 2 needs to be fixedly installed, the guide portion 8 and the screw 9 are made to correspond to the through hole of the insect-proof net main body and the connecting hole of the mounting portion. When the insect-proof net main body 2 needs to be disassembled, the guide portion 8 and the bolt 9 are rotated to a position away from the insect-proof net main body 2.

[0017] An annular slide rail 10 is arranged on the front end face of the guide portion 8, and a knob 11 is arranged on the annular slide rail 10. The knob 11 is provided with an annular slide groove matching the annular slide rail 10, so that the knob 11 can rotate stably on the annular slide rail. One end of the screw rod 9 passes through the guide portion 8, the insect-proof net main body 2 and is threadedly connected with the mounting portion 4, and the other end passes through the annular slide rail 10 and is threadedly connected with the knob 11. By rotating the knob 11, the screw rod 9 is driven to move horizontally and be threadedly connected to the connecting hole of the mounting portion 4, or be separated from the connecting hole of the mounting portion 4 and the through hole of the insect-proof net main body 2. This structure enables the insect-proof net main body 2 to be quickly connected and separated from the outer frame 1 without the need for external tools to assist the operation. The installation and disassembly are convenient, which is convenient for the later maintenance of the net plate and improves the maintenance efficiency.

[0018] The top and bottom of the mounting portion 4 are symmetrically provided with reinforcing plates 12 in an isosceles trapezoidal structure, the short bottom sides of the two reinforcing plates 12 are connected to each other, and the long bottom sides of the two reinforcing plates 12 are respectively connected to the top and bottom of the mounting portion 4, and the reinforcing plates 12 with an isosceles trapezoidal structure can increase the structural strength and structural stability of the mounting portion 4.
