The invention provides a truss structure of a stretching mechanism, which comprises a plurality of truss units, and the plurality of truss units are connected in series in an unfolded state and nested in a folded state; each truss unit comprises an upper frame, a transverse rod, an inclined rod, a first longitudinal rod, a lower frame and a second longitudinal rod; the upper frame is located over the lower frame and corresponds to the lower frame, first longitudinal rods are fixedly connected to the lower sides of the four ends of the upper frame, second longitudinal rods are fixedly connected to the upper sides of the four ends of the lower frame, the lower ends of the first longitudinal rods are fixedly connected with the upper ends of the corresponding second longitudinal rods through second connecting pieces, and a transverse rod is fixedly connected between every two adjacent second connecting pieces; a plurality of inclined rods are fixedly connected to the second connecting piece, one end of each inclined rod is connected with the second connecting piece, and the other end of each inclined rod is fixedly connected with the upper frame or the lower frame; a locking structure is arranged on the inner side of the upper frame, and a locking pin is arranged on the outer side of the lower frame. The structure has the characteristics of light weight, good expansibility, high bearing efficiency and convenience in maintenance.

    本发明提供了一种伸展机构的桁架结构,包括多个桁架单元,多个桁架单元在展开状态下串联,在收拢状态下嵌套;桁架单元包括上框、横杆、斜杆、第一纵杆、下框和第二纵杆;上框位于下框的正上方且与下框相对应,上框的四端下侧均固定连接有第一纵杆,下框的四端上侧均固定连接有第二纵杆,第一纵杆的下端与对应第二纵杆的上端通过第二连接件固定连接,相邻两个第二连接件之间固定连接有横杆;第二连接件上固定连接有多个斜杆,斜杆的一端与第二连接件连接,另一端与上框或所述下框固定连接;上框的内侧设置有锁定结构,下框的外侧设置有锁定销。该结构具有轻量化、拓展性好、承载效率高、便于维护的特点。
