Abstract:
A flat desk. Supporting rods (2) under a desktop board (1) comprise first supporting rods (21) and second supporting rods (22). Strip-shaped grooves (23) are provided on the inside of the supporting rods (2). The top end of a part of the strip-shaped grooves (23) arranged at the first supporting rods (21) and the bottom end of a part arranged at the second supporting rods (22) respectively are provided with fixing pins (24). Two supporting rods (2) arranged on either short side of the desktop board (1) are connected via a telescoping element (3). The telescoping elements (3) respectively are fixed on either end in the strip-shaped grooves (23) via the corresponding fixing pins (24). The telescoping elements (3) are connected to a controller (8) via driving elements. A lifting/lowering knob (41) is provided on the surface of the desktop board (1). The lifting/lowering knob (41) is connected to the controller (8). The controller (8) detects the degree of rotation of the lifting/lowering knob (41), controls the extension and retraction of the telescoping elements (3) via the driving elements, and controls the separation and joining of the first supporting rods (21) and the second supporting rods (22), thus implementing the lifting and lowering of the desktop board (1). The flat desk allows the height at which same is used to be adjusted autonomously as required for use, is applicable for people of different ages and height; moreover, the need for manual locking is obviated, and the tendency of becoming loose and unstable when being lifted/lowered is prevented.
