Glass fiber reinforced plastic centrifugal fan with air inlet sealing device

The utility model discloses a glass fiber reinforced plastic centrifugal fan with an air inlet sealing device, which relates to the technical field of glass fiber reinforced plastic centrifugal fans, and comprises a fan main body, the surface of the fan main body is fixedly connected with a connecting mechanism, the surface of the connecting mechanism is provided with a sealing piece, and the sealing piece comprises a conduction piece. And a filtering piece is installed in the conduction piece, and the surface of the conduction piece is in threaded connection with a sealing cover. A conduction pipe is pushed anticlockwise, the conduction pipe rotates anticlockwise to drive a connecting column and a ball to rotate anticlockwise, at the moment, the ball extrudes a push plate in an elastic assembly located in a second containing hole, and due to the effect of a spring, the push plate moves leftwards after being extruded, so that the push plate is pushed to move leftwards. When the sealing element is dismounted,
