Liftable adjusting table column

Abstract

The invention discloses a liftable adjusting table column which comprises an outer upright tube, a middle upright tube, an outer screw rod tube, an inner screw rod tube, an outer screw rod, an inner screw rod, an outer screw rod nut, an inner screw rod nut, a motor box and a driving motor, wherein the driving motor is mounted inside the motor box; a first bearing is connected with the upper end ofthe outer screw rod; one end of the first bearing is connected with the inner screw rod screw nut; an inner screw rod guide block is connected with the inner screw rod; the inner screw rod guide block is connected with the outer screw rod; one end of the outer screw rod tube is connected with the inner screw rod nut; the other end of the outer screw rod tube is connected with the middle upright column tube through an outer screw rod tube fixing base; one end of the inner screw rod tube is connected with the outer screw rod nut; the other end of the inner screw rod tube is connected with an inner screw rod tube fixing base; the outer upright column tube is connected with the inner screw rod tube fixing base through a connecting plate. Therefore, stable lifting transmission can be achieved,the inner screw rod nut and the outer screw rod nut are uniformly stressed, the fatigue degree can be reduced, the service life can be prolonged, and particularly, the liftable adjusting table columnis smart in structural design, reasonable in overall arrangement, and simple and convenient to mount.

Description

technical field [0001] The invention relates to the technology in the field of desks, in particular to a liftable and adjustable desk column. Background technique [0002] Desk is a very common office equipment in the office, but most of the desks are fixed and cannot be adjusted, and cannot adapt to changes in the office environment and the needs of users, which makes office workers prone to fatigue during the work process, and office resources are not available. To effective use, therefore, adjustable desks appear. Most of the adjustable desks in the prior art use a motor to drive the screw to realize the lifting adjustment of the desk. Due to the poor rationality of its structural design, the transmission instability of the lifting structure and the force of the linkage structure are caused. Too large, prone to fatigue and other problems. And, the existing lift-adjustable table column structure has defects such as troublesome installation, which limits the efficiency of...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention aims at the deficiencies of the prior art, and its main purpose is to provide a liftable and adjustable table column, whose structural design is coincidental and reasonable, which solves the problem of unstable transmission of the lifting structure and excessive force of the linkage structure. , prone to fatigue and other problems
