DETAILED DESCRIPTION

[0019] Example, by Figure 1-4 The utility model comprises two columns 1, and one end of the two columns 1 close to each other is fixedly connected with a connecting seat 2, and the side of the connecting seat 2 close to the column 1 is fixedly connected with a protrusion 3, and the protrusion 3 is embedded in the column 1, and the side of the connecting seat 2 away from the column 1 is fixedly connected with a connecting block 4, and a connecting sleeve 5 is installed between the two connecting seats 2, and the top and bottom of the connecting sleeve 5 are respectively provided with an adaptation groove 6, and the connecting block 4 is adapted to be installed in the adaptation groove 6, and a plurality of bolts 9 are respectively penetrated and connected on the four sides of the outer side of the connecting sleeve 5, and the connecting block 4 and the connecting sleeve 5 are fixedly connected by bolts 9.

[0020] Four bolt mounting holes 7 are respectively provided on the four outer sides of the connecting sleeve 5, and two threaded holes 8 are respectively provided on the four outer sides of the connecting block 4. The bolts 9 are located inside the bolt mounting holes 7 and extend into the threaded holes 8, and the outer surfaces of the bolts 9 are threadedly connected with the inside of the threaded holes 8. The bolt mounting holes 7 facilitate the installation of the bolts 9, and the bolts 9 can fix the connecting block 4 and the connecting sleeve 5 together.

[0021] A connecting ear 13 is welded and connected to the four outer sides of the connecting sleeve 5, and a groove 10 is opened on the four outer sides of the connecting sleeve 5. The groove 10 is located between the four bolt mounting holes 7, and the connecting ear 13 extends to the inside of the groove 10 close to the side of the connecting sleeve 5. The connecting ear 13 is adapted to the groove 10. A circular hole 11 is respectively provided at the top and bottom of the groove 10. Four nut grooves 12 are respectively provided at the top and bottom of the connecting sleeve 5. The circular hole 11 is connected to the nut groove 12. The adapting groove 6 is located between the four nut grooves 12. A connecting rod 14 is connected to the top of the connecting ear 13, and the connecting rod 14 passes through the circular hole 11 and extends to the inside of the nut groove 12, and both ends of the connecting rod 14 are respectively connected with a nut 15 through a thread, and the nut 15 is located in the nut groove 12. The connecting ear 13 is selectively installed according to actual needs. During installation, the mounting ear 13 can be inserted into the groove 10 first, and then the mounting ear 13 and the connecting sleeve 5 can be welded. Moreover, since the position of the mounting ear 13 is limited in advance, the position accuracy of the mounting ear 13 during welding is higher. Then, through the cooperation of the connecting rod 14 and the nut 15, the connecting pipe 14 passes through the connecting sleeve 5 and the mounting ear 13, which adds a safety for the mounting ear 13, so that the mounting ear 13 is installed on the connecting sleeve 5 with higher firmness and safety.

[0022] Working principle:

[0023] When connecting two columns 1, firstly, the connecting seat 2 is fixedly connected at the end of the column 1 with anchor bolts, and the protrusion 3 on the connecting seat 2 is embedded in the column 1. Then, when assembling and connecting the two columns 1, it is only necessary to install a connecting sleeve 5 between the two connecting seats 2, insert the connecting block 4 on the connecting seat 2 into the adapting groove 6, and then pass the bolt 9 through the bolt installation hole 7 and extend to the threaded hole 8 to fix the connecting block 4 and the connecting sleeve 5 together.

[0024] If it is necessary to install a crossbeam at the connection between the two columns 1, a connecting ear 13 can be installed on the corresponding surface of the connecting sleeve 5 in advance and the connecting ear 13 can be inserted into the groove 10 and welded and fixed. Then, the connecting rod 14 is inserted downward from the nut groove 12 corresponding to the top of the connecting sleeve 5. The connecting rod 14 passes through the round hole 11 and the connecting ear 13. Then, the nut 15 is screwed on the end of the connecting rod 14. The nut 15 will eventually be located in the nut groove 12. At this time, the position of the connecting rod 14 is fixed. The connecting rod 14 can further improve the firmness of the connecting ear 13 installed on the side of the connecting sleeve 5. The above operations need to be completed in advance before connecting the two columns 1.
