[0027] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Please refer to Figures 1 to 6 As shown, a children's study desk of this utility model includes a desktop, adjustable table legs, a bookshelf, and an extension mechanism. The adjustable table legs are provided on both sides of the lower surface of the desktop, the bookshelf is provided on the upper surface of the desktop, and the extension mechanism is connected to the desktop.

[0029] The expansion mechanism includes an expansion drive component, an expansion board, and a leveling component. A sliding groove is provided on both sides of the desktop. One of the expansion boards is slidably connected to one of the sliding grooves. The expansion drive component is located in the middle of the desktop. One side of each expansion board is connected to the expansion drive component. A receiving groove is provided on the expansion board, and the leveling component is located inside the receiving groove.

[0030] The working principle of this utility model is as follows: In actual children's learning and use, books and other items can be placed on the desktop, and items can be placed on the bookshelf. The height of the desktop can be adjusted by raising and lowering the table legs. When the desktop needs to be extended, the extension drive component can be activated to push out the extension plates on both sides and let the extension plates slide out in the slide groove. Then the leveling component is activated to make the height of the leveling component level with the desktop. Items can then be placed on the unfolded leveling component.

[0031] Furthermore, a baffle is provided on the other side of each of the expansion plates.

[0032] As can be seen from the above description, it is beneficial to cover the slide rail with a baffle, making the overall device more aesthetically pleasing.

[0033] Furthermore, the extended drive assembly includes a rotating drive component, a drive wheel, and a drive plate. The rotating drive component is installed in the middle of the lower surface of the desktop. The desktop has a drive groove inside, which is located between two sliding grooves and is interconnected. The drive wheel is rotatably connected to the inside of the drive groove. A drive plate is provided on each side of the drive groove, and the drive plates are engaged with the drive wheel. The rotating drive component is driven by the drive wheel. One end of one drive plate is fixedly connected to one side of one extended plate.

[0034] As can be seen from the above description, when it is necessary to control the extension plate to extend, the rotating drive component can be operated to drive the drive wheel to rotate. Then the drive wheel engages with the drive plates on both sides and drives the drive plates to move. At the same time, the drive plates drive the extension plate to extend.

[0035] Furthermore, the drive plate is provided with toothed grooves on the side near the drive wheel that are adapted to the drive wheel, and the drive plate engages with the drive wheel through the toothed grooves.

[0036] As can be seen from the above description, it is beneficial for the drive wheel to drive the drive plate better through the tooth groove.

[0037] Furthermore, each of the drive plates is provided with a limit block at the other end, which is used to limit the range of movement of the drive plate within the drive groove.

[0038] As can be seen from the above description, this helps to limit the movement range of the drive board and prevent the expansion board from falling out of the slide.

[0039] Furthermore, the leveling component includes a leveling plate and a plurality of first linear drive members. The lower part of the receiving groove is provided with a plurality of first linear drive members. The leveling plate is slidably connected to the upper part of the receiving groove. All first linear drive members are linearly driven connected to the leveling plate.

[0040] As can be seen from the above description, when it is necessary to align the supplementary plate with the desktop, each of the first linear drive components can be operated simultaneously, causing the first linear drive components to drive the supplementary plate to rise and align with the desktop.

[0041] Furthermore, the height-adjustable table leg includes a stable base plate, a second linear drive component, and a lifting plate. The lower part of the second linear drive component is detachably connected to the stable base plate, the upper part of the second linear drive component is connected to the lower surface of the lifting plate, and the upper surface of the lifting plate is detachably connected to the lower surface of the tabletop.

[0042] As can be seen from the above description, when the height of the desktop needs to be adjusted, the second linear drive can be activated, so that the second linear drive can drive the desktop to rise or fall through the lifting plate.

[0043] Furthermore, it also includes control switches, which are electrically connected to the lifting table legs, the extended drive assembly, and the leveling assembly, respectively.

[0044] As can be seen from the above description, it makes it more convenient for users to control the overall device.
