Abstract

The invention relates to a height-adjustable table leg. The height-adjustable table leg comprises a fixed outer tube, a movable inner tube and multiple rolling parts, wherein the movable inner tube has two first outside surfaces and two second outside surfaces which are mutually parallel; furthermore, the movable tube can be movably in sleeving connection with the fixed outer tube in the height direction; the multiple rolling parts can be arranged on the first or second outside surfaces in a manner of rolling in situ; the rolling parts locally protrude out of the first or second outside surfaces, and are in contact with the tube wall of the fixed outer tube; and therefore, when the movable inner tube moves, the multiple rolling parts can roll. Due to design of the rolling parts, the friction force between the fixed outer tube and the movable inner tube can be effectively reduced.

Description

technical field [0001] The invention relates to a table leg, in particular to a height-adjustable table leg. Background technique [0002] Common desks, computer desks or office desks, in order to be able to adapt to the needs of different users for the height of the desktop, a group of adjustment devices are usually arranged in its structure to allow users to adjust the height of the table legs at any time. Taking the commonly used height-adjustable table legs as an example, it mainly includes a fixed outer tube and a movable inner tube pierced through the fixed inner tube. The table legs can be adjusted by moving the movable inner tube up and down relative to the fixed outer tube. height effect. [0003] However, it is easy to generate friction between the fixed outer tube and the movable inner tube, and then produce the problems of surface wear and abnormal sound between the fixed outer tube and the movable inner tube. There is still room for improvement. Contents of ...
