[0017] The advantages of the present invention are:

[0018] The circular tube body in this structure includes a tube body section, a top flange section, a bottom flange section, an upper limit section and a lower limit section, and the tube body section, the top flange section, the bottom flange section, the upper limit section and the lower limit section are an integrated structure, which avoids the subsequent step of welding the top flange section or the bottom flange section to the tube body section, saves manpower, and avoids tedious welding operations. At the same time, the circular tube body with an integrated structure has better structural strength, avoiding welding defects that are inevitable in the welding process, so that during actual use of this structure, there will be no risk of the outer flange being dislocated or even detached from the flange of the circular tube body, avoiding safety hazards.

[0019] The top of the top plate is also provided with a plurality of positioning protrusions, and the bottom end of the top flange section is also provided with positioning grooves corresponding to the positioning protrusions. The positioning protrusions cooperate with the positioning grooves to achieve the limitation between the top plate and the top flange section, preventing the top plate from rotating during the process of connecting the structure with the connecting through hole of another bed foot through the connecting stud, or during the process of threaded connection of the structure with the bed board through the connecting stud.
