Abstract
A butterfly fin internal thread bushing is made of aluminum alloy. The butterfly fin internal thread bushing structurally comprises a circular sleeve body, butterfly fins, screw holes, an annular tooth, internal threads and inner steps. The lower end of the inner diameter of the circular sleeve body is a large bore diameter, and the upper end of the inner diameter of the circular sleeve body is a small bore diameter. The inner steps are formed at the position where the large bore diameter intersects with the small bore diameter. The internal threads are arranged on the inner wall of the lower end of the circular sleeve body. The annular tooth is arranged on the outer wall of the lower end of the circular sleeve body. The upper end of the circular sleeve body is connected with the semi-circular-arc-shaped butterfly fins. The screw holes are formed in the two sides of each butterfly fin. The butterfly fin internal thread bushing has the advantages that one end of the butterfly fin internal thread bushing is connected with a corresponding connecting piece, the other end of the butterfly fin internal thread bushing is fastened through screws, and connection is firmer and more reliable.
