[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1-4The utility model provides a technical solution: a building support steel structure pillar, comprising a support column 1, the inner cavity of the support column 1 is slidably connected to a top column 2, the top of the top column 2 passes through the support column 1 and extends to the outside of the support column 1 and is rotatably connected to a support beam 3 through a bearing seat, and the bottom of the inner cavity of the support column 1 is provided with an adjustment mechanism 4 for adjusting the top column 2 so as to facilitate the lifting of the top column 2;

[0026] By configuring the top column 2, the support beam 3, and the adjustment mechanism 4, when in use, the top column 2 is moved by the adjustment mechanism 4, and the top column 2 can then drive the support beam 3 to move. By adjusting the height of the support beam 3, installation is facilitated. At the same time, since the adjustment mechanism 4 is arranged in the inner cavity of the support column 1, the adjustment mechanism 4 can avoid contact with the outside air, thereby preventing the threaded column 91 in the adjustment mechanism 4 from rusting due to contact with the outside air, thereby increasing the service life of the threaded column 91.

[0027] Support plates 5 are installed on both sides of the bottom of the support beam 3, and the bottom ends of the support plates 5 are connected to fixed tubes 6. Positioning plates 7 are installed on the tops of both sides of the support column 1. Positioning grooves are installed on the outer sides of the positioning plates 7. Positioning teeth 8 are installed equidistantly inside the positioning grooves. The inner ends of the fixing tubes 6 respectively pass through the positioning grooves and extend to the inside of the positioning grooves to engage with the positioning teeth 8. The inner cavity of the fixing tube 6 is provided with a locking mechanism 9 for locking the fixing tube 6 to facilitate the positioning of the fixing tube 6. The bottom end of the support column 1 is provided with a fixing mechanism 10 for fixing the support column 1 to facilitate the installation of the support column 1;

[0028] Through the arrangement of the support plate 5, the fixed tube 6, the positioning plate 7, the positioning teeth 8, the locking mechanism 9 and the fixing mechanism 10, when the top column 2 drives the support beam 3 to move, the support beam 3 drives the support plate 5 and the fixed tube 6 to move, and the fixed tube 6 drives the locking mechanism 9 to move. After the movement is completed, the lock tongue 41 in the locking mechanism 9 will engage with the positioning teeth 8, so that the fixing tube 6 can be fixed, which is convenient for supporting the support beam 3 and improving the stability of the support beam 3.

[0029] See also Figures 1-4 The locking mechanism 9 includes a lock tongue 41, which is slidably connected to the inner cavity of the fixed tube 6. The inner ends of the lock tongue 41 respectively penetrate the fixed tube 6 and the positioning groove and extend to the inner cavity of the positioning groove to engage with the positioning teeth 8. The outer side of the fixed tube 6 is connected to a cover plate 42, and the outer end of the lock tongue 41 is connected to a return spring 43. One end of the return spring 43 is in contact with one side of the cover plate 42. When the fixed tube 6 moves, the lock tongue 41 will be driven to move. The moving lock tongue 41 retracts into the fixed tube 6 under the action of the corresponding positioning teeth 8 and compresses the return spring 43. After passing the corresponding positioning teeth 8, it will return to its original position under the action of the return spring 43 and engage with the next positioning teeth 8. This reciprocating process can fix the fixed tube 6 after the movement is completed.

[0030] The adjusting mechanism 4 includes a threaded column 91, which is rotatably connected to the inner cavity of the support column 1 through a bearing seat. The top of the threaded column 91 passes through the top column 2 and extends to the inner cavity of the top column 2.

The outer ends of the rotating shaft 92 respectively pass through the support column 1 and extend to the outside of the support column 1 and are connected to a threaded cap 93. The threaded cap 93 is rotated by a tool, and the rotating threaded cap 93 drives the rotating shaft 92 to rotate. The rotating shaft 92 drives the threaded column 91 to rotate through the bevel gear. Since the threaded column 91 is threadedly connected to the top column 2, the rotating threaded column 91 drives the top column 2 to move.

[0031] The fixing mechanism 10 includes a base plate 101, which is fixedly installed on the bottom end of the support column 1. Fixing holes are equidistantly provided on the surface of the base plate 101, and fixing bolts 102 are provided at corresponding positions of the fixing holes. The base plate 101 can be fixed by the fixing bolts 102, which facilitates the installation and fixation of the support column 1. Support sliders are equidistantly installed on the bottom of the surface of the top column 2, and a support groove is provided in the inner cavity of the support column 1 and at the corresponding position of the support slider. The surface of the support slider is slidably connected to the inner cavity of the support groove, which can position the top column 2 to avoid driving the top column 2 to rotate when the threaded column 91 rotates, thereby affecting the normal movement of the top column 2.

[0032] Limiting blocks are installed on both sides of the lock tongue 41, and a limiting groove is provided in the inner cavity of the fixed tube 6 and at the corresponding position of the limiting block. The surface of the limiting block is slidably connected to the inner cavity of the limiting groove, which can limit the lock tongue 41 to prevent the lock tongue 41 from deflecting when moving, thereby affecting the clamping effect of the lock tongue 41. Protective shells 11 are installed on both sides of the support column 1 and at the corresponding position of the threaded cap 93 through fixing screws, which can protect the threaded cap 93 and improve the service life of the threaded cap 93. The cover plate 42 is connected to the outer side of the fixed tube 6 by the positioning screws, which is convenient for disassembly. When disassembly is required, it is convenient to disassemble the lock tongue 41, so that it is out of the clamping state with the positioning teeth 8, which is convenient for disassembly.

[0033] A sealing ring 12 is provided on the surface of the top column 2, and the bottom of the sealing ring 12 is connected to the top of the support column 1, which can seal the connection between the top column 2 and the support column 1 to prevent external water from entering the interior of the support column 1 through the connection, thereby causing erosion to the internal components of the support column 1, and playing a protective role. The outer end of the lock tongue 41 is connected to the inner side of the reset spring 43 with a pull rod 13. When disassembly is required, the cover plate 42 can be removed by tools, the reset spring 43 can be removed, and then the pull rod 13 is pulled to disengage the lock tongue 41 from the positioning teeth 8, which is convenient for disassembly.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
