[0008] By adopting the above technical scheme, the effect of the rotation of the second rotating shaft is achieved.

[0009] Furthermore, the limiting block is provided with a limiting groove matched with the fixing column, and the maximum outward rotation angle of the fixing column and the second rotating shaft is 90°.

[0010] By adopting the above technical scheme, the effect of limiting the rotation angle of the fixing column is achieved.

[0011] Furthermore, a through hole is opened at the end of the fixing column, and the inner wall of the through hole is made of a smooth material.

[0013] Further, a rubber layer is provided on the surface of the limiting groove, and the limiting groove is adhesively connected to the rubber layer.

[0015] Further, through holes matching with the first rotating shaft are provided in the interiors of the three groups of main bodies, and the cross-section of the through holes is the same as that of the first rotating shaft.

[0016] By adopting the above technical solution, the rotation of the three groups of main bodies sharing the first rotating shaft can be achieved.

[0017] In summary, the main beneficial effects of the present utility model are as follows: through the structure in which the first rotating shaft drives the three groups of main bodies to rotate respectively and the combination of the second rotating shaft and the fixed column structure, the effect of freely adjusting the angle is achieved, so as to achieve the effect of facilitating the adjustment of the angle of the overall grid structure.

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.

[0025] The following will describe the embodiments according to the overall structure of the present utility model.

[0026] A building steel structure grid, such as Figures 1-5As shown, it includes three groups of main bodies 1. The three groups of main bodies 1 are movably connected to a first rotating shaft 2. A groove 3 is formed inside the main body 1. A second rotating shaft 4 is arranged inside the groove 3. A fixing column 5 is fixedly connected to the surface of the second rotating shaft 4. A limiting block 7 is fixedly connected inside the groove 3. The utility model rotates freely through the first rotating shaft 2 and the second rotating shaft 4, thereby achieving the function of freely adjusting the angle, and thus achieving the effect of facilitating the adjustment of the angle of the overall grid structure.

[0027] Please refer to Figure 4 and Figure 5 , both ends of the second rotating shaft 4 are fixedly connected with a connecting shaft 9. Connecting holes 10 matching with the connecting shaft 9 are formed on both sides of the groove 3. The utility model achieves the function of rotating the second rotating shaft 4 through the cooperation of the connecting shaft 9 and the connecting holes 10.

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , a limiting groove 8 matching with the fixing column 5 is formed in the limiting block 7. The maximum rotation angle of the fixing column 5 and the second rotating shaft 4 outwards is 90°. The utility model achieves the function of limiting the angle of the fixing column 5 through the limiting groove 8.

[0029] The working principle of the utility model is as follows: During use, the three groups of main bodies 1 are all movably connected through the first rotating shaft 2, and the three groups of main bodies 1 can rotate at different angles respectively. A groove 3 is formed inside the main body 1, and connecting holes 10 are formed at both ends of the inner side of the groove. Both ends of the second rotating shaft 4 are fixedly connected with a connecting shaft 9. The inside of the groove 3 is movably connected through the connecting holes 10 and the connecting shaft 9 fixedly connected to both ends of the second rotating shaft 4;

[0030] During the use process, a fixing column 5 is fixedly connected to the surface of the second rotating shaft 4. A through hole 6 is formed at the end of the fixing column 5, and the inner wall of the through hole 6 is made of a smooth material, which is convenient for the installation of bolts;

[0031] Specifically, the steel pipe with holes drilled is inserted into the fixing column 5, and bolts and nuts are used to fixedly connect through the through hole 6 and the steel pipe, thereby achieving the effect of rapid installation;

[0032] During the use process, a limiting block 7 is fixedly connected inside the groove 3, and a limiting groove 8 matching with the fixing column 5 is formed in the limiting block 7;

[0033] Specifically, when the second rotating shaft 4 drives the fixing column 5 to rotate outwards, the maximum angle is limited to 90° through the limiting groove 8, thereby achieving the effect of limiting the angle when the steel pipe rotates;

[0034] Furthermore, by changing the angle of the steel pipe through the second rotating shaft 4 and the fixing column 5, the function of adjusting the angle of the steel pipe to form the overall grid structure is achieved;

[0035] During use, a rubber layer is adhesively connected to the surface of the limit groove 8, thereby achieving the effect of preventing the fixed column 5 from colliding and damaging the steel pipe when rotating.
