[0018] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings. The present utility model can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present utility model more thorough and comprehensive.

[0019] Embodiment

[0020] As Figures 1 to 6, the spliced joint of the box column of the present utility model includes an upper box column 1, a lower box column 2, bolts 3, nuts 4 and a splicing mechanism. The upper box column 1 is located above the lower box column 2. The upper box column 1 and the lower box column 2 are spliced together through the splicing mechanism, and the splicing mechanism is fixedly connected by bolts 3 and nuts 4. Through the above settings, when splicing and fixing the upper box column 1 and the lower box column 2, only the bolts 3 and nuts 4 are needed to make the splicing mechanism fasten the upper box column 1 and the lower box column 2 together, and only by removing the bolts 3 and nuts 4 from the splicing mechanism can the disassembly of the upper box column 1 and the lower box column 2 be completed. It is convenient to use, facilitates the disassembly of the upper box column 1 and the lower box column 2, is convenient to use, and has high practicability.

[0021] As Figure 1 , the splicing mechanism includes two groups of end panels 5, two groups of fixing plates 6 and two groups of mounting plates 7. The two groups of end panels 5 are respectively fixedly installed on the upper box column 1 and the lower box column 2. The two groups of fixing plates 6 are respectively fixedly installed on the two groups of end panels 5. The two groups of mounting plates 7 are respectively fixedly installed on the two groups of fixing plates 6. Through holes communicating up and down are provided on both groups of mounting plates 7, and the through holes on the two groups of mounting plates 7 are coaxial. The bolts 3 pass through the through holes on the two groups of mounting plates 7 and are screwed and fixed with the nuts 4. When fixedly splicing the upper box column 1 and the lower box column 2, the two groups of mounting plates 7 on the upper box column 1 and the lower box column 2 are butted against each other, then the bolts 3 are passed through the through holes on the two groups of mounting plates 7, and then the nuts 4 are screwed and fixed with the bolts 3, so that the two groups of mounting plates 7 are squeezed and fixed by the bolts 3 and the nuts 4; it facilitates the installation and fixation of the upper box column 1 and the lower box column 2.
