A computer desk with liftable and adjustable desktop for living and studying

Abstract

This invention relates to the field of furniture technology and discloses a height-adjustable computer desk for living and studying. It includes a desktop and hollow legs fixedly installed on both sides of its lower end. Hollow rods are fixedly installed on the sides of the two sets of hollow legs that are close to each other. An adjustment and stabilizing component is provided on the inner side of both sets of hollow rods, and elastic elements are provided on the inner side of the hollow legs. A foot-controlled drive lever rotates a bevel gear transmission pair and a sleeve, converting the rotational motion into the vertical lifting motion of the driven rod. This achieves desktop height adjustment while simultaneously using a corner plate to push an expansion plate to expand laterally, adaptively increasing the bottom support area. This ensures the computer desk operates stably, smoothly, and reliably throughout its entire height adjustment range. This invention solves the problems of traditional height-adjustable computer desks where the center of gravity shifts upward, stability decreases, and wobbling and tilting occurs after raising the height. It is also easy to assemble, durable, and combines practicality, stability, and safety, making it suitable for various living and studying scenarios.
