The invention belongs to the technical field of design of aircraft canopy supporting rod fastening structures, and particularly relates to an aircraft canopy supporting rod fastening structure and a fastening method thereof.The aircraft canopy supporting rod fastening structure comprises a force bearing block, a bolt and a nut; the bearing block is hinged to one end of the supporting rod; the other end of the supporting rod is hinged to the cabin cover, the cabin cover is installed on the cabin force bearing frame, and a strip-shaped installation hole is formed in the cabin force bearing frame. The bolt penetrates through the strip-shaped through hole, and the head is rectangular; anti-rotation grooves are formed in the top ends of the bolts; the nut is screwed on the bolt; the nut is a butterfly nut; the rectangular heads of the adjusting bolts are parallel to the strip-shaped mounting holes in the cockpit force bearing frame and can penetrate through the strip-shaped mounting holes, the rectangular heads of the adjusting bolts are perpendicular to the strip-shaped mounting holes in the cockpit force bearing frame, the nuts are tightened, the force bearing block can be fastened to the cockpit force bearing frame, and therefore the supporting rods are fastened, and the cockpit cover is supported at the opening position.
本申请属于飞机座舱盖支撑杆紧固结构设计技术领域,具体涉及一种飞机座舱盖支撑杆紧固结构及其紧固方法,其中,飞机座舱盖支撑杆紧固结构,包括承力块、螺栓、螺母;承力块铰接在支撑杆一端;支撑杆另一端铰接在座舱盖上,座舱盖在座舱承力框上安装,座舱承力框上开设有条形安装孔;螺栓贯穿条形通孔设置,头部呈矩形;螺栓顶端具有防转槽;螺母螺接在螺栓上;螺母为蝶形螺母;调整螺栓矩形的头部与座舱承力框上的条形安装孔平行,能够穿过条形安装孔,调整螺栓矩形的头部与座舱承力框上的条形安装孔垂直,将螺母拧紧,能够将承力块紧固在座舱承力框上,以此对支撑杆进行紧固,将座舱盖支撑在打开位置。
