Abstract

The invention relates to a table foot with adjustable height, which comprises a fixed outer tube, a movable inner tube and a plurality of rolling parts. Wherein, the movable inner tube has two first outer surfaces and two second outer surfaces parallel to each other, and the movable tube can displaceably sleeve the fixed outer tube along the height direction. The plurality of rolling elements are rotatably provided on the first or second outer surface, and the rolling elements partially protrude from the first or second outer surface and contact the pipe wall of the fixed outer pipe, so that when all When the movable inner tube is displaced, the plurality of rolling elements can roll. The frictional force between the fixed outer tube and the movable inner tube can be effectively reduced through the design of the rolling elements.

Description

technical field [0001] The present invention is a table foot, especially a table foot with adjustable height. Background technique [0002] In order to adapt to different users' demands for the height of the desk, a common desk, computer desk or desk is usually provided with a set of adjustment devices in its structure, so that the user can adjust the height of the desk legs at any time. Taking the conventional height-adjustable table legs as an example, it mainly includes a fixed outer tube and a movable inner tube passing through the fixed inner tube. The table legs can be adjusted by the up and down displacement of the movable inner tube relative to the fixed outer tube. high effect. [0003] However, friction is likely to occur between the fixed outer tube and the movable inner tube, resulting in the problems of surface abrasion and abnormal sound between the fixed outer tube and the movable inner tube. There is still room for improvement. SUMMARY OF THE INVENTION ...
