The invention discloses a large-scale space truss structure suitable for on-orbit assembly, which comprises a polyhedral joint, a connecting piece, a truss rod and an oblique inhaul cable, a lock cylinder is in threaded connection with a joint screw rod in the polyhedral joint, and the connecting piece is in locking connection with a lock cylinder groove or a lock cylinder concave hole through a connecting piece steel ball; a connecting piece screw rod is inserted into a rod piece screw hole for threaded connection, the oblique inhaul cable fixes a truss through a spring, and the structural stability is guaranteed; by repeating the steps, the assembly of the large space truss structure with a plurality of periodic units can be completed. The structure is simple, the rigidity of the polyhedral joint connecting position is high, mounting and dismounting are convenient and fast, and the requirement for on-orbit assembling of the large space truss structure in the future is met.

    本发明公开一种适于在轨组装的大型空间桁架结构,包括多面体关节、连接件、桁架杆,斜向拉索,锁芯与多面体关节中的关节螺杆进行螺纹连接,连接件通过连接件钢珠与锁芯凹槽或锁芯凹孔锁定连接,连接件螺杆插入杆件螺孔进行螺纹连接,斜向拉索通过弹簧固定桁架,保证结构稳定性;重复上述步骤,可以完成具有多个周期单元的大型空间桁架结构组装。本发明结构简单、多面体关节连接处刚度高,具有安装拆卸便捷等优点,满足于未来大型空间桁架结构在轨组装的需求。
