The connection structure between the large louver and the ring beam generally requires drilling rows of holes on the ring beam during production, and then using a rivet gun to rivet. During installation, the louver rotating parts are fixed with pin screws, and the louver shaft rotates on the pin screws to achieve the rotation of the large louver. Its main defects are: this connection method is complex and has many installation accessories. The louver rotating parts rotate on the pin screws for too long, and the rivet is easily damaged by slipping due to the influence of torque for a long time. The damaged ring beam can only be scrapped, resulting in a high claim rate.
