Lifting upright post with rolling assemblies

Abstract

The invention discloses a lifting upright post with rolling assemblies. The lifting upright post comprises an inner pipe, an outer pipe with which the inner pipe is sleeved and a lifting assembly fordriving the inner pipe to lift. The inner pipe and the outer pipe are in sliding connection, at least two rolling assemblies for preventing the inner pipe from shaking are arranged between the inner pipe and the outer pipe, the rolling assemblies are arranged on the inner pipe, and adjusting gaskets for pressing the rolling assemblies on the outer pipe are arranged between the rolling assemblies and the inner pipe. The distance between the ends, facing the inner wall of the outer pipe, of the rolling assemblies and the outer wall of the inner pipe can be adjusted by selecting the thickness ofthe adjusting gaskets, in other words, the distance between the ends, facing the inner wall of the outer pipe, of the rolling assemblies and the outer wall of the inner pipe can be adjusted accordingto the gap between the outer pipe and the inner pipe, so that the rolling assemblies always abut against the inner wall of the outer pipe, and the inner pipe is prevented from shaking in the lifting process; and rolling friction is formed between the rolling assemblies and the inner wall of the outer pipe, so that lifting of the inner pipe in the outer pipe is smoother.

Description

technical field [0001] The invention belongs to the field of lifting columns, and in particular relates to a lifting column with a rolling assembly. Background technique [0002] At present, the lifting column has been widely used. During the lifting process of the lifting column, the friction plate between the inner tube and the outer tube can prevent the inner tube from shaking. However, the friction plate increases the force on the inner tube during the lifting process. Resistance, so that the lifting of the inner tube is not smooth, and prone to jamming and other phenomena. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a lifting column with a rolling assembly that lifts smoothly and stably. [0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a lifting column with a rolling assembly, including an inner tube, an outer tube sleeved outside t...

[0002] At present, the lifting column has been widely used. During the lifting process of the lifting column, the friction plate between the inner tube and the outer tube can prevent the inner tube from shaking. However, the friction plate increases the force on the inner tube during the lifting process. The resistance makes the inner tube not go up and down smoothly, and it is prone to jamming and other phenomena
