Document Type and Number:
WIPO Patent Application WO/2021/023167
Kind Code:
A1
Abstract:
Provided is a four-section lifting/lowering vertical column, comprising a lifting/lowering assembly and four connected lifting/lowering tubes; the four lifting/lowering tubes are, from the inside to the outside, a first lifting/lowering tube (110), a second lifting/lowering tube (120), a third lifting/lowering tube (130), and a fourth lifting/lowering tube (140); the lifting/lowering assembly comprises three screw assemblies and a driving assembly which drives the three screw assemblies to operate simultaneously; the lifting/lowering assembly is fixed in the second lifting/lowering tube (120), and the three screw assemblies are respectively connected in the first lifting/lowering tube (110), the third lifting/lowering tube (130), and the fourth lifting/lowering tube (140); or, the lifting/lowering assembly is fixed in the third lifting/lowering tube, and the three screw assemblies are respectively connected in the first lifting/lowering tube (110), the second lifting/lowering tube (120), and the fourth lifting/lowering tube (140). The three screw assemblies are driven simultaneously by means of the drive assembly, and the three screw assemblies respectively drive different lifting/lowering tubes up or down away from the lifting/lowering tubes of the fixed drive assembly, enabling the four lifting/lowering tubes of the lifting/lowering vertical column to rise visually at the same time, improving the overall lifting speed of the lifting/lowering vertical column.
