The invention provides a connecting structure and a connecting system, and the connecting structure comprises a first connecting body which is provided with a connecting through hole and a limiting through hole; a second connecting body which is provided a conical hole; a conical stud which penetrates through the conical hole, the limiting through hole and the connecting through hole; a conical matching structure which is arranged in the limiting through hole and is provided with a first conical surface matched with the conical part and a limiting cylindrical surface matched with the inner wall of the limiting through hole; a conical nut which is in threaded connection with the first cylindrical part and is provided with a second conical surface matched with the conical hole; and a fastening nut which is in threaded connection with the second cylindrical part and abuts against the end face, deviating from the second connecting body, of the first connecting body. The conical hole, the limiting through hole and the connecting through hole are sequentially distributed; and the conical stud is provided with a first cylindrical part, a conical part and a second cylindrical part which are connected in sequence. According to the invention, the technical problem that the vibration load is difficult to effectively transmit to the aircraft or the section of the aircraft in the vibrationtest of the large aircraft is alleviated.
本发明提供了一种连接结构及连接系统,该连接结构包括第一连接体,其设有连接通孔和限位通孔;第二连接体,其设有锥形孔,锥形孔、限位通孔和连接通孔依次分布;锥形螺柱,其穿过锥形孔、限位通孔和连接通孔,锥形螺柱具有依次连接的第一圆柱部、锥形部和第二圆柱部;设于限位通孔中的锥状配合结构,锥状配合结构设有与锥形部相配合的第一锥面、和与限位通孔的内壁相配合的限位柱面;螺接于第一圆柱部的锥形螺母,锥形螺母设有与锥形孔相配合的第二锥面;螺接于第二圆柱部的紧定螺母,紧定螺母与第一连接体的背离第二连接体的端面抵接。通过本发明,缓解了大型飞行器的振动试验中,难以将振动载荷有效地传递至飞行器或者其部段的技术问题。
