[0024] Embodiment 1
[0025] See also Figures 1 to 4, the present utility model provides a technical solution: a detachable steel structure connector, including a connecting block 1, a threaded hole 2 is provided on the surface of the connecting block 1, a positioning plate 3 can be inserted into the connecting block 1, a hole is provided on the side of the positioning plate 3, a bearing 4 is arranged in the hole, a rotating rod 5 is inserted into the bearing 4, and a rotating plate 6 is sleeved on the surface of the rotating rod 5; a second bottom plate 7, a bottom plate 8 is arranged on the side of the second bottom plate 7, a positioning frame 9 is arranged on the surface of the bottom plate 8, and a steel structure 10 can be inserted into the positioning frame 9;
[0026] When in use, when it is necessary to install the steel structure 10 at an oblique angle, the steel structure 10 is fixed in the positioning frame 9, and then the positioning bolt 16 is rotated to separate the bottom plate 8 from the second bottom plate 7, and then the bottom plate 8 is rotated. When the bottom plate 8 rotates to an appropriate angle, the bottom plate 8 and the second bottom plate 7 are fixedly connected by using the positioning bolt 16. In this way, the connected steel structure 10 can be fixed at an inclined angle through the rotational connection between the bottom plate 8 and the second bottom plate 7. Such a fixing method can flexibly adjust the angle of the installed steel column, and the installation and disassembly are convenient and flexible, greatly reducing the construction difficulty during disassembly and assembly, which is relatively convenient.
[0027] Embodiment Two
[0028] On the basis of Embodiment One, in order to facilitate the angle rotation of the steel structure 10, a bottom plate 8 and a second bottom plate 7 are provided. An installation bolt 11 can be screwed into the threaded hole 2, and the positioning plate 3 can be fixed inside the connecting block 1 by using the installation bolt 11. The steel structure 10 is fixed in the positioning frame 9 by bolts. A fixing plate 13 is arranged on the side of the second bottom plate 7. The fixing plate 13 is in a "C"-shaped plate structure, and the fixing plate 13 is fixed on the rotating plate 6 by using a second bolt 14. Positioning holes 15 are provided on the surfaces of both the second bottom plate 7 and the bottom plate 8, and the second bottom plate 7 and the bottom plate 8 are fixed by using a positioning bolt 16;
[0029] When in use, when it is necessary to rotate the steel structure 10, the positioning bolt 16 can be rotated to separate the bottom plate 8 from the second bottom plate 7, and then the bottom plate 8 can be rotated so that the rotation angle of the bottom plate 8 meets the angle at which the steel structure 10 needs to be inclined. Then, the positioning bolt 16 is inserted into the positioning hole 15 to fix the bottom plate 8 and the second bottom plate 7. In this way, the steel structure 10 can be inclined at an angle more conveniently.
[0030] Embodiment Three
[0031] On the basis of the second embodiment, in order to facilitate the steel structure 10 to flip up and down and tilt at an angle, a rotating plate 6 is provided, a rotating rod 5 is fixedly connected to the inner ring surface of the bearing 4, a limiting groove 12 is provided at one end of the rotating rod 5, and the limiting groove 12 is a polygonal column structure. A support rod 17 is provided on the side of the rotating plate 6, and a spring 18 and a movable plate 19 are sleeved on the surface of the support rod 17. A limiting rod 20 is provided on the inner side of the movable plate 19, and the limiting rod 20 is a polygonal column structure. One end of the limiting rod 20 can be inserted into the limiting groove 12, one end of the spring 18 is fixedly connected to the side of the rotating plate 6, and the other end of the spring 18 is fixedly connected to the inner side of the movable plate 19, and the movable plate 19 can slide on the support rod 17;
[0032] When in use, the movable plate 19 can be pulled to move the movable plate 19 on the support rod 17, so that the limiting rod 20 set on the side of the movable plate 19 can be disengaged from the limiting groove 12, and then the rotating plate 6 can be rotated, so that the steel structure 10 can be turned over. When it is rotated to a suitable angle, the movable plate 19 is released, and the movable plate 19 is reset by the elastic force of the spring 18 so that the limiting rod 20 is inserted into the limiting groove 12, which is more convenient for fixing the rotating plate 6 after the rotation angle.
[0033] Working principle: In actual use, when the steel structure 10 needs to be installed at an angle, the steel structure 10 is fixed in the positioning frame 9, and then the positioning bolts 16 are rotated to disengage the bottom plate 8 from the second bottom plate 7, and then the bottom plate 8 is rotated. When the bottom plate 8 is rotated to a suitable angle, the positioning bolts 16 are used to fix the bottom plate 8 and the second bottom plate 7. The steel structure 10 connected in this way can be connected through the rotation connection between the bottom plate 8 and the second bottom plate 7 to achieve the fixation of the inclination angle of the steel structure 10. This fixing method can flexibly adjust the angle of the installed steel column, and the installation and disassembly are convenient and flexible, which greatly reduces the construction difficulty during disassembly and assembly. It is more convenient, thus avoiding the existing connecting parts that can only be installed at a vertical angle and there is no way to install at an angle. When encountering a situation where an oblique installation is required, only welding can be used for connection. The strength of the weld in the welding connection method is low, and the position of the steel column is fixed after welding, which makes subsequent disassembly and assembly difficult and has low flexibility.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
