Positioning holes that mate with the positioning posts 230 are provided on the side wall of the left side plate 21 near the left column 22 and the side wall of the back plate 23 near the left column 22. During installation, the positioning posts 230 on the first left connecting plate 227 near the left side plate 21 are inserted into the positioning holes on the left side plate 21, and then the second left connecting plate 228 is connected to the left side plate 21 with bolts. Similarly, the positioning posts 230 on the first left connecting plate 227 near the back plate 23 are inserted into the positioning holes on the back plate 23, and then the second left connecting plate 228 is connected to the back plate 23 with bolts. Specifically, multiple reinforcing plates are provided on the inner sidewall of the left outer arc plate 221 along the vertical direction. The two ends of the reinforcing plates are respectively connected to the two first left connecting plates 227, thereby connecting the left outer arc plate 221 and the two first left connecting plates 227 into a whole. The specific connection relationship is welding.

[0055] The left column 22 and the right column 24 are symmetrically arranged with respect to the tabletop assembly 1. Please refer to the corresponding diagram for details. Figures 4-6Specifically, in this embodiment, the right column 24 includes a right outer arc-shaped plate, a right inner upper arc-shaped plate, a right inner mounting plate, a right upper cover plate, a right support cover plate, and a right lower cover plate. Both ends of the right outer arc-shaped plate are connected to a first right connecting plate, which is perpendicular to the ends of the right outer arc-shaped plate. A second right connecting plate is connected to the lower part of the first right connecting plate, which is perpendicular to the first right connecting plate and extends outwards from the right column 24. Specifically, the connection relationships between the right outer arc-shaped plate, the right inner upper arc-shaped plate, the right inner mounting plate, the right upper cover plate, the right support cover plate, and the right lower cover plate are as follows: both ends of the right inner upper arc-shaped plate are connected to the two first right connecting plates respectively; the right upper cover plate is connected to the upper sidewall of the right outer arc-shaped plate, the upper sidewall of the first right connecting plates, and the right inner upper arc-shaped plate. The lower right cover plate is connected to the lower side wall of the right outer arc plate, the lower side wall of the first right connecting plate, and the lower side wall of the right inner mounting plate. The right inner mounting plate protrudes from the right inner upper arc plate. The right support cover plate covers the upper side wall of the right inner mounting plate to form a right boss 27, which is used to support the table assembly 1 and works together with the left boss 26. In this embodiment, the right inner mounting plate is L-shaped, thus forming a columnar boss. The right outer arc plate, the right inner upper arc plate, the right inner mounting plate, the right upper cover plate, the right support cover plate, and the right lower cover plate surround the inner cavity of the right column 24. Correspondingly, the two ends of the right inner mounting plate are detachably connected to the two second right connecting plates, and the two second right connecting plates are detachably connected to the back plate 23 and the right side plate 25, respectively, which can be connected by bolts. In this embodiment, the right outer arc plate, right inner upper arc plate, right inner mounting plate, right upper cover plate, right support cover plate, and right lower cover plate are welded together to form a whole. This allows for direct assembly and transport as a single unit after factory processing. Assembly is simple: just bolt one second right connecting plate, the end connecting plate of the right inner mounting plate, and the right side plate 25 together; and bolt another second right connecting plate, the end connecting plate of the right inner mounting plate, and the back plate 23 together. Disassembly is convenient. Furthermore, the lower side wall of the right lower cover plate is also connected to a foot 8 for support, and the lower outer side wall of the right inner mounting plate is provided with a right fixing plate, which can be installed on the ground to secure the lectern.

[0056] Specifically, to facilitate the connection between the right column 24 and the right side plate 25, multiple positioning posts 230 are vertically arranged on the first right connecting plate. Positioning holes that mate with the positioning posts 230 are provided on the side wall of the right side plate 25 near the right column 24 and on the side wall of the back plate 23 near the right column 24. During installation, the positioning posts 230 on the first right connecting plate near the right side plate 25 are inserted into the positioning holes on the right side plate 25, and then the second right connecting plate is connected to the right side plate 25 with bolts. Similarly, the positioning posts 230 on the first right connecting plate near the back plate 23 are inserted into the positioning holes on the back plate 23, and then the second right connecting plate is connected to the back plate 23 with bolts. Specifically, multiple reinforcing plates are also vertically arranged on the inner side wall of the right outer arc plate. The two ends of each reinforcing plate are connected to two first right connecting plates, thus connecting the right outer arc plate and the two first right connecting plates into a single unit. The specific connection relationship is welding.

[0057] Specifically, the lower outer walls of the left inner mounting plate 223 and the right inner mounting plate are respectively connected to a left junction box 5 and a right junction box 6. Both the left and right junction boxes 5 and 6 have inlet holes 51, and the upper ends of both the left and right inner mounting plates have outlet holes 2231. The inner cavity of the left junction box 5 communicates with the inner cavity of the left column 22 through a connecting hole on the left inner mounting plate 223. The inner cavity of the right junction box 6 communicates with the inner cavity of the right column 24 through a connecting hole on the right inner mounting plate. Both the inner cavities of the left column 22 and the right column 24 are connected to the tabletop assembly through outlet holes 2231. The inner cavity of the socket 4 is connected to the component 1, allowing wires from the ground to enter the left junction box 5 through the inlet hole 51, then into the inner cavity of the left column 22, and finally through the outlet hole 2231 into the inner cavity of the socket 4 for electrical connection. Similarly, wires from the ground can also enter the right junction box 6 through the inlet hole 51, then into the inner cavity of the right column 24, and finally through the outlet hole 2231 into the inner cavity of the socket 4 for electrical connection. The actual wire entry depends on the usage. In the unused stage, sealing plates can be installed at the inlet hole 51 and the through hole. The sealing plates are connected to the side walls of the inlet hole 51 and the outlet hole 2231 by several connecting rods. When using the corresponding outlet hole 2231 and inlet hole 51, external personnel can break the connecting rods with external force to remove the corresponding sealing plates.

The rear end of the rotating plate 15 is rotatably connected to the front end of the table pocket 14 via a hinge. The front end of the rotating plate 15 is detachably connected to the lower end of the partition 16 via bolts. Thus, when it is necessary to inspect the electronic components in the rear installation space 122, the screws between the rotating plate 15 and the partition 16 can be removed, and the rotating plate 15 can be rotated downwards to open the rear installation space 122 for inspection. After the inspection is completed, the rotating plate 15 can be fixed to the partition 16 with bolts.
