[0040] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model. Example 1

[0041] like Figures 2-8 As shown, this embodiment discloses a single-bar support structure, including:

[0042] The base 2 has a socket 21 on its upper part;

[0043] The support rod 1 has its lower end inserted into the insertion slot 21;

[0044] Among them, one of the support rod 1 and the insertion groove 21 is provided with a wedge-tightening boss 11, the wedge-tightening boss 11 has an inclined surface, and the inclined surface is inclined towards the insertion direction of the support rod 1; the other is provided with a rib 22. When the support rod 1 is inserted into the insertion groove 21, the wedge-tightening boss 11 and the rib 22 are tightly abutted.

[0045] Furthermore, in this embodiment, the base 2, as the core part of the support structure, is provided with a plug-in groove 21, and the opening of the plug-in groove 21 is set at an angle. The bottom end of the support rod 1 is plugged into the plug-in groove 21, and the upper end of the support rod 1 is connected to the table board 3. This connection method provides strong support and stability for the overall structure.

[0046] In some other embodiments, the upper end of the support rod 1 is not limited to the connection to the tabletop 3, but can also be connected to a reading panel or a posture corrector. This design makes the scope of application of this embodiment wider and can be flexibly adjusted according to user needs to support applications with different functions.

[0047] Further, in this embodiment, the base 2 is provided with moving wheels, so that the entire structure can be conveniently adjusted in position. This design enables the learning desk to be flexibly moved according to different use scenarios, increasing the convenience of use. At the same time, the upper end of the base 2 is connected to the seat 4, forming a desk and chair integrated learning desk, optimizing the use of space. In other embodiments, the base 2 only serves as a support, focusing on supporting other equipment such as posture correctors, reading racks or displays, etc. This adjustable design enables the support structure to play different roles in different situations.

[0048] Further, in terms of material selection, the support rod 1 in this embodiment adopts sheet metal parts, which have high strength and durability, and can withstand large weight and pressure. The base 2 adopts injection molded parts. The wedge-shaped boss 11 is formed by stamping process. In order to facilitate the installation and adjustment of the support rod 1, an end cap 12 is welded at the lower end opening of the support rod 1, which blocks the opening to prevent foreign matter from entering the inside of the support rod 1.

[0049] The end cap 12 is provided with a first air vent 13 and four fastening holes 14. The first air vent 13 is designed very cleverly, which can effectively guide the gas inside the support rod 1 out, reducing the resistance caused by air resistance. During the extension and retraction of the support rod 1, the change of internal air pressure will generate resistance, affecting the smooth movement of the support rod 1. The air vent design of the first air vent 13 effectively reduces the influence of air pressure on the movement of the support rod 1, improving the smoothness and stability of the lifting operation.

[0050] Further, in this embodiment, the design of the slot bottom of the insertion slot 21 also pays great attention to details. The slot bottom is provided with four through holes 23 and a second air vent 24 corresponding to the positions of the fastening holes 14, and the support rod 1 and the insertion slot 21 are connected by the fastening member 5 through the through holes 23 and the fastening holes 14. The design of the second air vent 24 is in harmony with the first air vent 13, which can smoothly guide the air inside the insertion slot 21 out, preventing air accumulation causing air pressure resistance. When the support rod 1 is inserted into the insertion slot 21, the air vent function of the second air vent 24 ensures that the support rod 1 can be smoothly inserted to the bottom, avoiding the situation that the support rod 1 cannot be inserted to the bottom due to air pressure resistance. Such design not only improves the installation experience of the support rod 1, but also increases the stability and use reliability of the overall structure.

[0051] Specifically, in combination with Figures 5-8As shown, in the embodiment, the wedge protrusions 11 are arranged on the surface of the support rod 1. The support rod 1 is inserted into the insertion slot 21 from top to bottom, and the inclined surface is inclined towards the bottom of the insertion slot 21. Specifically, the insertion slot 21 adopts a waist hole design, and the wedge protrusions 11 are symmetrically arranged on both sides of the support rod 1. The wedge protrusions 11 are convex structures on the sheet metal part, and the inclined surface is inclined downward, that is, the height of the wedge protrusions 11 gradually decreases from top to bottom. At the same time, the ribs 22 are arranged in a ring shape along the inner wall of the insertion slot 21, and each rib 22 protrudes from the surface of the insertion slot 21.

[0052] In other embodiments, the wedge protrusions 11 are arranged on the surface of the support rod 1. When the support rod 1 is inserted into the insertion slot 21 from bottom to top, the inclined surface is inclined towards the opening of the insertion slot 21. That is, the insertion slot 21 adopts a splicing structure, and the insertion slot 21 is a reverse cone shape. After the support rod 1 is inserted into the insertion slot 21 from bottom to top, the cover plate at the bottom of the insertion slot 21 is connected with the base 2. At this time, the inclined surface of the wedge protrusions 11 is arranged upwardly.

[0053] Similarly, in other embodiments, the wedge protrusions 11 are arranged on the side wall of the insertion slot 21, and the support rod 1 is inserted into the insertion slot 21 from top to bottom. The inclined surface is inclined towards the opening of the insertion slot 21, that is, the inclined surface of the wedge protrusions 11 is inclined upwardly.

[0054] Or in other embodiments, the wedge protrusions 11 are arranged on the side wall of the insertion slot 21, and the support rod 1 is inserted into the insertion slot 21 from bottom to top. The inclined surface is inclined towards the bottom of the insertion slot 21, that is, the inclined surface of the wedge protrusions 11 is inclined downwardly.
