For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of on-line checkingi ultrasonic inspection lining bar subcutaneous port syndeton, comprise appearance cylindrical and the nose rod iron of the mutual concavo-convex docking that diameter is identical and recessed end rod iron, one side end face of described nose rod iron is provided with a cylindrical boss, one side end face of described recessed end rod iron is provided with the indent circular hole be consistent with the profile of cylindrical boss, it is characterized in that: under the exterior arc surface of described nose rod iron, 2mm place is provided with an artificial cross-drilled hole, the position that the circumferential periphery of described recessed end rod iron is positioned at below artificial cross-drilled hole is provided with eccentric bevel for welding, the side end face welding groove that described nose rod iron contacts with recessed end rod iron, the base of described cylindrical boss and nose rod iron end contact place are provided with the excessive face of circular cone at outward-dipping 30 degree of angles, the periphery of described indent circular hole is provided with interior button screw thread, and the outer circumference surface of described cylindrical boss is provided with outer button screw thread, and garden, the bottom periphery of described indent circular hole is provided with the withdrawing inclined-plane of miter angle, the circumferential periphery of described cylindrical boss is provided with the 45 degree inclined-planes corresponding with withdrawing inclined-plane, and the circumferential periphery of described indent circular hole is provided with the inclined-plane at 30 degree of corresponding angles of face excessive in circular cone.
As the further improvement of the technical program, the bound fraction that described recessed end rod iron and the contact end face of nose rod iron are positioned at more than artificial cross-drilled hole uses silica gel to close to be connected.
Compared with prior art, bevel for welding is not established in the contact jaw musculus cutaneus lower opening position of the utility model on-line checkingi ultrasonic inspection lining bar subcutaneous port syndeton, use silica gel to close to connect, fundamentally eliminate welding scaling loss to the impact of subcutaneous port, other positions adopt eccentric bevel for welding, cooperation center thread connecting mode, effectively can ensure the degree of accuracy of subcutaneous port, can also meet the strength of joint requirement of lining bar simultaneously.
