When in use, first fix the single-row frame to one side of the truss through the fixed joint, and then adjust the position of the articulated joint plug according to the position of the truss on the other side, and after the adjustment is completed, fix the position of the articulated joint by bolts and nuts passing through the circular holes and the oblong holes, and then clamp the truss pipe on the other side and fix it.

[0005] Preferably, the flexible joint also includes a fixed part, a rotating part, a locking screw and a locking nut. The fixed part with an arc-shaped inner side is arranged on the outer end of the insert tube, one end of the fixed part is rotatably connected to one end of the rotating part with an arc-shaped inner side, and the other end of the fixed part is rotatably connected to the locking screw. The other end of the rotating part is provided with a slot for the locking screw to pass through. When the fixed part and the rotating part clamp the tube body of the truss, the locking screw passes through the slot and is fixed by the locking nut.

[0006] The utility model has the advantages of reasonable structural design, and a movable joint with fine-adjustable position is arranged at one end of the single-row frame, which can effectively connect the single-row frame between the trusses on both sides, simplify the connection process, and ensure the connection stability.

DETAILED DESCRIPTION

[0011] The present invention is further described in detail below in conjunction with embodiments and specific implementation methods.

[0012] like Figure 1-3 As shown, a single-row frame and truss articulated connection structure comprises a single-row frame 1 and a truss 2. A articulated joint 3 and a fixed joint 4 are respectively provided at both ends of the single-row frame 1. The single-row frame 1 is connected between the two trusses 2 via the articulated joint 3 and the fixed joint 4.

[0013] The single-row frame 1 includes a pair of main pipe bodies 11 parallel to each other, and the flexible joint 3 includes an insert pipe 31, a fixing portion 33, a rotating portion 34, a locking screw 35 and a locking nut 36. The insert pipe 31 is inserted into the end of the main pipe body 11. The main pipe body 11 has circular holes 12 on both sides near the end, and an oblong hole 32 corresponding to the position of the circular hole 12 is opened on the insert pipe 31. The insert pipe 31 inserted into the end of the main pipe body 11 is fixedly connected by bolts and nuts passing through the circular hole 12 and the oblong hole 32. The fixing portion 33 with an arc-shaped inner side is arranged on the outer end of the insert pipe 31. One end of the fixing portion 33 is rotatably connected to one end of the rotating portion 34 with an arc-shaped inner side, and the other end of the fixing portion 33 is rotatably connected to the locking screw 35. The other end of the rotating portion 34 is provided with a notch 37 for the locking screw 35 to pass through. When the fixing portion 33 and the rotating portion 34 clamp the pipe body of the truss 2, the locking screw 35 passes through the notch 37 and is fixed by the locking nut 36.
