Description

Technical Field

[0001] The utility model relates to the technical field of displays, and in particular to a lightweight display base with adjustable height. Background Art

[0002] A lightweight, height-adjustable monitor stand is designed to reduce weight while offering height adjustment. These stands are typically made of lightweight materials, such as aluminum or carbon fiber, to reduce weight and enhance portability. They also feature height adjustment, allowing you to adjust the monitor's height to suit different usage scenarios and ergonomic requirements.

[0003] Currently, in terms of height adjustment function, the adjustment methods of existing monitor bases are relatively limited. Some use a simple card slot structure to adjust several fixed heights, which cannot meet the user's precise needs for different heights. Others use more complex hydraulic or pneumatic pressure adjustment methods. Although a certain degree of height adjustment can be achieved, there are often problems such as insufficient stability and insufficient smooth adjustment. Although existing monitors and bases are made of lightweight materials, these adjustment methods usually require a large operating force and are not convenient to use. Even if some existing height-adjustable bases can be adjusted by electric drive, it is easy to increase costs and dependence on power supply, and cannot be adjusted without power supply; some bases require standing to pull the monitor to raise the base. This method is not only laborious, but also extremely inconvenient for some users who have limited mobility or need to sit in a seat for a long time to work. For this reason, we propose a lightweight height-adjustable monitor base. Utility Model Content

[0004] The top end of the guide rail is fixedly provided with a toothed connecting strip which is cooperatively connected with the toothed connecting strip, and the bottom end of the guide rail is connected with the toothed connecting strip by the toothed connecting strip.

The setting of this structure can keep the driving assembly stable during use, and the knob can be directly rotated to make the fourth bevel gear, the third bevel gear, the first bevel gear, and the second bevel gear mesh and rotate in sequence, and then the threaded rod is rotated to adjust the height of the guide sleeve.

[0006] As an improvement of the above technical solution, a limiting groove is provided on the surface of the third bevel gear, and an insertion rod that is engaged with the limiting groove is inserted into the inner wall of the opening of the adjustment groove. The end of the insertion rod is fixedly connected to a plug, and the plug is L-shaped. The side wall of the base is provided with sockets distributed circumferentially at the opening of the adjustment groove. The sockets and the plugs are inserted into each other, so that after the display is adjusted to a certain height, the insertion rod is inserted into the third bevel gear to limit the rotation state of the third bevel gear, thereby limiting the use of the entire drive assembly and maintaining the use height of the display.

[0007] As an improvement to the above technical solution, the limiting groove and the insertion rod both have hexagonal cross-sections, which makes it convenient to limit the rotation state of the third bevel gear by using the edges after the insertion rod is inserted.

[0008] As an improvement of the above technical solution, a recess is provided on the top surface of one end of the adjustment groove close to the third bevel gear, a bearing is inserted between the top of the inner wall of the recess and the top surface of the base, the connecting shaft is fixed to the inner wall of the bearing, and the diameter of the recess is larger than the diameter of the fourth bevel gear, so that the rotation of the fourth bevel gear has a stable support effect.

The outer surface of the guide cover 5 is sleeved with a guide sleeve 8. The top side wall of the guide sleeve 8 is fixedly connected to the side wall of the display 1. The inner wall of the bottom end of the guide sleeve 8 is fixedly connected to the side wall of the guide cover 5. The side wall of the guide cover 5 is provided with a guide port 10. The two ends of the threaded sleeve 9 are slidably matched with the inner wall of the guide port 10. A knob 19 is provided at the eccentric position of the top surface of the base 2, and a driving assembly is provided between the knob 19 and the threaded rod 7.

[0018] Specifically, the side wall of the base 2 is provided with an adjustment groove 11 connected to the mounting port 6. The inner wall of the adjustment groove 11 is fixedly connected to the rotating shaft 12 through a bearing. The drive assembly includes a first bevel gear 13 and a third bevel gear 15 fixed at both ends of the rotating shaft 12. The top surface of the first bevel gear 13 is meshed with a second bevel gear 14 fixed to the bottom end of the threaded rod 7. The top of the third bevel gear 15 is meshed with a fourth bevel gear 18. A connecting shaft 17 is fixedly connected between the top of the fourth bevel gear 18 and the knob 19.

[0019] In the embodiment, the structure can keep the driving assembly stable during use, and the knob 19 can be directly rotated to rotate the fourth bevel gear 18, the third bevel gear 15, the first bevel gear 13 and the second bevel gear 14 in sequence, and then rotate the threaded rod 7 to adjust the height of the guide sleeve 8.

[0020] Specifically, the third bevel gear 15 is provided with a limiting groove 20 on the surface, the adjusting groove 11 is provided with a plug rod 21 matched with the limiting groove 20, the end of the plug rod 21 is fixedly connected with a plug bolt 22, the plug bolt 22 is L-shaped, the side wall of the base 2 is provided with a plurality of plug holes 23 circumferentially distributed at the opening of the adjusting groove 11, and the plug holes 23 are matched with the plug bolt 22.

[0021] In the embodiment, after the display 1 is adjusted to a certain height, the plug rod 21 is inserted into the third bevel gear 15 to limit the rotation state of the third bevel gear 15, thereby limiting the use of the whole driving assembly, and the use height of the display 1 is kept.

[0022] Specifically, the limiting groove 20 and the plug rod 21 are both hexagonal sections.

[0023] In the embodiment, after the plug rod 21 is inserted, the edges are used to limit the rotation state of the third bevel gear 15.

[0024] Specifically, the end of the adjusting groove 11 close to the third bevel gear 15 is provided with a notch 16 on the top surface, a bearing is inserted between the inner wall top end of the notch 16 and the top surface of the base 2, the connecting shaft 17 is fixed to the inner wall of the bearing, and the diameter of the notch 16 is greater than the diameter of the fourth bevel gear 18.

[0025] In the embodiment, the rotation of the fourth bevel gear 18 can be stably supported.

[0026] During operation, when the display 1 needs to be raised, the user rotates the knob 19 located at the eccentric position of the top surface of the base 2. The rotation of the knob 19 drives the connecting shaft 17 to rotate, thereby rotating the fourth bevel gear 18. The fourth bevel gear 18 meshes with the third bevel gear 15, causing the third bevel gear 15 to rotate. The third bevel gear 15 drives the first bevel gear 13 to rotate through the rotating shaft 12. The first bevel gear 13 meshes with the second bevel gear 14, thereby rotating the second bevel gear 14 fixed to the bottom end of the threaded rod 7. The threaded rod 7 starts to rotate under the action of the bearing. Due to the threaded transmission of the threaded sleeve 9 and the threaded rod 7, and the two ends of the threaded sleeve 9 slide with the inner wall of the guide port 10, the guide sleeve 8 starts to rise under the threaded cooperation of the threaded sleeve 9 and the threaded rod 7. The top side wall of the guide sleeve 8 is fixedly connected to the side wall of the display 1, so that the display 1 As the guide sleeve 8 rises, it rises. When the display 1 needs to be lowered, the knob 19 is rotated in the opposite direction, and the upper transmission process is repeated to make the threaded rod 7 rotate in the opposite direction, thereby making the guide sleeve 8 descend and driving the display 1 to lower its height. When the display 1 is adjusted to a suitable height, in order to maintain the height, the insertion rod 21 is inserted into the limiting groove 20 opened on the surface of the third bevel gear 15 to limit the rotation state of the third bevel gear 15. Since the rotation of the third bevel gear 15 is limited, the entire drive assembly cannot continue to work, thereby maintaining the use height of the display 1. The end of the insertion rod 21 is fixedly connected to the plug 22, and the plug 22 is L-shaped. The side wall of the base 2 is provided with a socket 23 circumferentially distributed at the opening of the adjustment groove 11. After the insertion rod 21 is inserted into the limiting groove 20, the plug 22 is inserted into the socket 23 to further fix the position of the insertion rod 21.

[0027] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
