Embodiment Construction

[0026] In order to make the technical solution of the present invention clearer, the present invention will be described in detail below through specific examples.

[0027] Such as Figure 1 to Figure 3 As shown, the present embodiment provides an intelligent elevating learning table, which includes a table body, and the table body is composed of a table top 1 and two elevating table legs 3 supporting the table top 1 . Each lift table leg 3 has an outer sleeve 31 and a movable inner tube 32 . The movable inner tube 32 is installed inside the outer tube 31, and the power mechanism 4 is installed inside the movable inner tube 32 for driving the outer tube to move vertically. The electric push rod is preferably used, because it is small in size and easy to install. The other top of the outer casing is fixedly connected with the desktop 1, and the power mechanism 4 is electrically connected with the control circuit board. The desktop is provided with an installation groove, the...
