The high-bearing-capacity connecting structure comprises an inner hole sleeve and an outer hole sleeve, the inner hole sleeve and the outer hole sleeve are each of a hollow rotary body structure and comprise a cylindrical section and a flanging section, the flanging section and the cylindrical section are coaxial and arranged at one end of the cylindrical section, internal threads are arranged on the inner wall of the cylindrical section of the inner hole sleeve, and external threads are arranged on the outer wall of the cylindrical section of the outer hole sleeve; the center of the outer hole sleeve is connected with a steel wire thread insert and serves as an external connector, the drawing allowable load acting on the steel wire thread insert is not lower than 1.5 kN, and the shearing allowable load acting on the steel wire thread insert is not lower than 10 kN. According to the invention, the requirement of large bearing capacity of a thin plate similar to a bearing cylinder type honeycomb sandwich plate is met.

    本发明涉及一种航天器承力筒的高承载连接结构,包括内孔套和外孔套,内孔套和外孔套均为中空回转体结构,包括圆柱段和翻边段,翻边段与圆柱段同轴,并设置在圆柱段一端,内孔套圆柱段内壁设置内螺纹,外孔套圆柱段外壁设置外螺纹;外孔套中心连接有钢丝螺套,作为对外接口,作用在钢丝螺套上的拉拔许用载荷不低于1.5kN,剪切许用载荷不低于10kN。本发明解决了类似于承力筒式蜂窝夹层板的薄板大承载需求。
