Figure 1-3 As shown, the plug-in type pipe truss steel structure described in the utility model comprises a bottom block 1, a top block 8, a first reserved groove 4, a second reserved groove 9 and a plug-in rod 7, wherein the first reserved groove 4 is opened at one end of the top of the bottom block 1, and the second reserved groove 9 is opened at one side of the bottom of the top block 8;

[0024] The first reserved groove 4 and the second reserved groove 9 are respectively provided with a first rotating block 5 and a second rotating block 10 through a rotating axis, and the first rotating block 5 and the second rotating block 10 are both provided with a plug-in groove 6 at the adjacent positions, and the top and bottom ends of the plug-in rod 7 are respectively plugged into the corresponding plug-in groove 6, and the two groups of the bottom blocks 1 are both provided with a sliding groove 21 at the adjacent positions, and a sliding block 22 is sleeved in the sliding groove 21, and a cross plate 11 is connected between the two groups of the sliding blocks 22, and a first sleeve block 12 is provided at the top of the cross plate 11 near the center, and a sleeve rod 16 is fixed in the first sleeve block 12 by a third bolt 15, and a second sleeve block 13 is provided at the bottom of the top block 8 near the center, and a guide sleeve 17 is fixed in the second sleeve block 13 by a second bolt 14, and the top of the sleeve rod 16 is located in the guide sleeve 17.

[0025] When in use, the height between the top block 8 and the bottom block 1 can be conveniently adjusted by the rotation of the second rotating block 10 in the second reserved groove 9, the rotation of the first rotating block 5 in the first reserved groove 4, and the sliding of the sliding block 22 in the sliding groove 21, and the sleeve rod 16 can be extended and retracted in the guide sleeve 17, so that the tube truss steel structure has a fixed height structure after installation, can adjust the height, and has a good flexibility effect when in use.

[0026] For example, Figure 2-3As shown, the utility model also includes that a positioning bolt 18 is provided at one side of the bottom end of the guide sleeve 17 through a threaded hole, and a positioning screw hole 20 corresponding to the positioning bolt 18 is provided at one end of the sleeve rod 16 .

[0027] When in use, the positioning bolts 18 are tightened to connect and fix the positioning bolts 18 with the corresponding positioning screw holes 20 , so that after adjusting the height between the top block 8 and the bottom block 1 , the guide sleeve 17 and the sleeve rod 16 are locked and fixed.

[0028] For example, Figure 1-2 As shown, the utility model also includes that baffles 3 are fixed to the adjacent parts of the two groups of bottom blocks 1 by first bolts 2 .

[0029] When in use, the baffle plate 3 is used to limit the horizontal position of the sliding block 22 during sliding, thereby preventing the sliding block 22 from falling out of the sliding groove 21 .

[0030] For example, Figure 2 As shown, the utility model also includes that a rectangular through slot 19 is penetrated through one end of the baffle plate 3 near the center, and two ends of the transverse plate 11 pass through corresponding rectangular through slots 19 respectively.
