[0021] like Figure 1-5 As shown, this utility model provides a technical solution: a height-adjustable side table that can flip left and right, including a base frame 1, a first column 2 fixedly installed on the top of the base frame 1, a cylinder 17 fixedly installed inside the first column 2, a second column 4 fixedly connected to the telescopic end of the cylinder 17 by screws, the second column 4 being slidably connected to the inner side of the first column 2, a positioning sleeve 5 installed on the top of the first column 2, a rotating shaft 6 provided on the left side of the positioning sleeve 5, two panel fixing brackets 7 fixedly installed on the outer side of the rotating shaft 6, a desktop board 3 fixedly connected to the top of the two panel fixing brackets 7, and a central shaft 13 installed inside the positioning sleeve 5.

[0022] Furthermore, the base frame 1 is an I-shaped structure composed of two horizontal bars and one vertical bar, and the cross-section of the base frame 1 is a rectangle with a relatively small height.

[0023] Specifically, the thinner I-beam-shaped base frame 1 can be inserted into sofas, beds, etc. with lower height. This, combined with height adjustment and panel angle adjustment, helps to improve comfort during use.

[0024] Furthermore, four foot pads 8 are installed on the bottom of the bottom frame 1. The four foot pads 8 are located at the four corners of the bottom of the bottom frame 1, and the foot pads 8 are made of Teflon.

[0025] Specifically, the foot pads 8 located at the four corners can improve stability during use. The Teflon foot pads 8 have good sliding properties, reduce friction, and increase service life.

[0026] Furthermore, a first welding piece 10 is installed on the inner side of the positioning sleeve 5, and a spring 11 is fixedly installed on the left side of the first welding piece 10. The spring 11 is sleeved on the outside of the tightening handle 9. A second welding piece 12 is fixedly installed on the other end of the spring 11. The second welding piece 12 is fixedly installed on the inner side of the central shaft 13. The positioning sleeve 5 and the rotating shaft 6 are evenly provided with toothed grooves at their opposite ends.

[0027] Specifically, the toothed grooves on the positioning sleeve 5 and the rotating shaft 6 can be adjusted by tightening the handle 9, allowing them to rotate relative to each other. This allows the desktop 3 to be adjusted within the angle desired by the user, and the spring 11 maintains the state between them, improving flexibility and stability.

[0028] Furthermore, a clamp 15 is fixedly installed on the outer side of the top of the first column 2, and an eccentric handle 16 is rotatably connected to the side of the clamp 15.

[0029] Specifically, the eccentric handle 16 on the clamp 15 can fix the position of the second column 4 inside the first column 2, and can flexibly adjust the height of the desktop 3 to improve practicality.

[0030] Furthermore, a first friction plate 14 is installed on the inner side of the clamp 15, and a second friction plate 18 is installed on the outer side of the bottom of the second column 4. The first friction plate 14 and the second friction plate 18 are made of rubber.

[0031] Specifically, the rubber material has good friction resistance, which can maintain the position between the first column 2 and the second column 4 and improve the stability of use.

[0032] Working principle: First, a first column 2 is fixedly installed on the top of the base frame 1. A cylinder 17 is fixedly installed inside the first column 2. The telescopic end of the cylinder 17 is fixedly connected to a second column 4 by screws. The second column 4 is slidably connected to the inside of the first column 2, allowing the height of the second column 4 to be freely adjusted inside the first column 2. A positioning sleeve 5 is installed on the top of the first column 2. A rotating shaft 6 is set on the left side of the positioning sleeve 5. Two panel fixing brackets 7 are fixedly installed on the outside of the rotating shaft 6. The top of the two panel fixing brackets 7 is fixedly connected to the desktop 3. A central shaft 13 is installed inside the positioning sleeve 5, allowing the desktop 3 to be adjusted within a certain angle range, improving practicality. Second, Teflon feet 8 are installed at the bottom of the base frame 1. Four feet 8 are located at the four corners of the bottom of the base frame 1. The base frame 1 is an I-shaped structure composed of two horizontal bars and one vertical bar, which ensures good stability of the side table during use. Finally, a clamp 15 is fixedly installed on the outer side of the top of the first column 2. An eccentric handle 16 is rotatably connected to the side of the clamp 15. A first friction plate 14 is installed on the inner side of the clamp 15. A second friction plate 18 is installed on the outer side of the bottom of the second column 4. The first friction plate 14 and the second friction plate 18 are made of rubber. After adjusting the relative height between the first column 2 and the second column 4, the clamp 15 can fix the position. The first friction plate 14 and the second friction plate 18 can increase the friction between the first column 2 and the second column 4, thereby improving stability.
