DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Embodiment of the present utility model: As Figures 1 to 4 shown, a table frame structure of a back-to-back lifting table includes a pair of crossbeam frames 2 arranged side by side for installing a tabletop 1. At both ends of each crossbeam frame 2, there are installed lifting columns 3 that are synchronously lifted by a driver. The lifting column 3 includes a plurality of sliding tubes sleeved inside and outside and connected in a sliding manner. The outermost sliding tube is the fixed tube 4 located at the bottom. A connecting pipe 5 is connected between the fixed tubes 4 of the lifting columns 3 on the same side of the two crossbeam frames 2. A wire groove is connected between the connecting pipes 5 on both sides. The wire groove includes a groove body 7 and a cover body 8. The cross-section of the groove body 7 is in a U shape with an open upper end. The cover body 8 is rotatably connected to the top of the groove body 7. Openings 6 for the wire to enter and exit are provided on both sides of the bottom of the groove body 7. The cover body 8 can rotate relative to the groove body 7 to close the top of the groove body 7 or make the top of the groove body 7 in an open state. When the cover body 8 needs to be opened, the tabletop 1 is raised to a high position so that there is a relatively large distance between the tabletop 1 and the wire groove, and the cover body 4 will not interfere with the tabletop 1 during the rotation process.

[0016] As a preferred embodiment, since the workstations on both sides generally have their own wiring, and the cover body 8 will not interfere with the desktop panel 1 when it rotates when the desktop panel 1 is in a lower position, the cover body 8 at the top of the slot body 7 of the present application is a pair, which are respectively transferred to the two sides of the top of the slot body 7. The cover bodies 8 on both sides are respectively located under the desktop panel 1 on each side, and the two sides perform line sorting operations by opening and closing their own cover bodies 8. A pair of cover bodies 8 are adopted. When the cover body 8 is in a state of closing the top of the slot body 7, the cover body 8 is in a suspended state away from the transfer side of the slot body 7, and the stability is poor. To prevent the cover body 8 from falling off, a support limit member 17 is provided in the middle position of the slot body 7. The cover body 8 has a folded edge 9 away from the transfer side of the slot body 7, and a matching limit groove 10 is provided on the support limit member 17. When the cover body 8 rotates to the state of closing the top of the slot body 7, the support limit member 17 supports the cover body 8, and the folded edge of the cover body 8 is located in the limit groove 10.

[0017] As a preferred embodiment, a mounting component for installing a screen 11 is provided in the middle of the connecting pipes 5 on both sides. When the screen 11 is installed on the mounting component, it is located directly above the connection between the two cover bodies 8. An isolation screen 11 can be installed, and the cover body 8 does not interfere with the screen 11 when opening and closing. The screen 11 separates the two table tops 1 located on the crossbeam frame 2, so that the back-to-back lifting table with the table frame structure has good privacy.

[0018] As a preferred embodiment, the mounting component includes a pair of L-shaped mounting parts 12. The L-shaped mounting parts 12 are installed back to back on the connecting tube 5, and a slot for clamping the screen 11 is formed in the middle. The connecting tube 5 is provided with screw holes, and the mounting parts 12 are provided with corresponding waist-shaped holes 13. The screws pass through the waist-shaped holes 13 and are connected with the screw holes to connect the mounting parts 12 to the connecting tube 5. When the screws are loosened, the mounting parts 12 move a certain distance relative to the connecting tube 5, thereby adjusting the spacing of the slots for clamping the screen 11, which is suitable for plug-in installation of screens 11 of different thicknesses. The mounting parts 12 are also provided with screw holes. After the screen 11 is plugged into the slot, the screws are fixed to the screen 11 through the screw holes on the mounting parts 12, thereby achieving stable installation of the screen 11.

[0019] As a preferred embodiment, a connecting piece 14 is welded on the fixing tube 4 of the lifting column 3, and the connecting tube 5 is plugged and matched with the connecting piece 14. An end plate 15 is welded inside the connecting tube 5, and the end plate 15 is tilted. The connecting piece 14 has a corresponding inclined surface. The end plate 15 and the inclined surface of the connecting piece 14 are provided with vertically distributed screw holes. When the connecting tube 5 is plugged on the connecting piece 14, the end plate 15 and the inclined surface of the connecting piece 14 are tightly attached, and the screw holes on the end plate 15 are also aligned with the screw holes of the connecting tube 5. A mounting opening 16 is opened at the bottom of the connecting tube 5. The space inside the connecting tube 5 is small. Compared with the existing end plate 15 being vertical and the screw holes being horizontally distributed, it is necessary to enter the connecting tube 5 through the mounting opening 16 for turning operation. After the screws pass through the mounting opening 16, they are directly tilted upward and aligned with the screw holes to connect the end plate 15 with the connecting piece 14 to achieve the installation of the connecting tube 5, which is more convenient to operate.
