Further, be evenly provided with a plurality of the first projections on the medial surface of described groove, the first projection is distributed between described the first screwed hole, is evenly provided with a plurality of first grooves corresponding with the first projection on the side of described lower flange.When series connection, the cooperation by the first groove and the first projection, has further increased the stress surface while twisting, and has improved the anti-torsion ability of connecting portion.
Further, the inner surface of described the first groove is provided with watertight composition.Watertight composition is for preventing that rainwater from collecting in the gap between the first groove and the first projection, improved anti-corrosion ability of the present utility model.
Further, be evenly provided with a plurality of the second grooves on the medial surface of described groove, the second groove is distributed between described the first screwed hole, is evenly provided with a plurality of second projections corresponding with the second groove on the side of described lower flange.When series connection, the cooperation by the second groove and the second projection, has further increased the stress surface while twisting, and has improved the anti-torsion ability of connecting portion.
Further, the inner surface of described the second groove is provided with watertight composition.Watertight composition is for preventing that rainwater from collecting in the gap between the second groove and the second projection, improved anti-corrosion ability of the present utility model.
Further, described upper flange and lower flange consist of martensitic precipitation.Martensitic precipitation, such as modal 17-4PH martensite PH stainless steel, has very high intensity and good rustless property, the intensity of link position in the time of can improving series connection.
Further, described watertight composition consists of acrylonitrile-butadiene rubber.
In sum, advantage of the present utility model and beneficial effect are:
1. by the structure of upper flange and lower flange, when series connection, effectively increase the anti-torsion ability of connecting portion, greatly increased the intensity of connecting portion;
2. pass through the first groove and the first projection, or the cooperation of the second groove and the second projection, further increased the stress surface while twisting, improved the anti-torsion ability of connecting portion;
3. be provided with watertight composition, improved anti-corrosion ability of the present utility model.
