Benefits of technology

The present invention provides a simple and low-cost height adjusting structure for a desk. It uses a driving gear to simultaneously rotate through a connecting rod, which then engages with toothed sections in a supporting tube to adjust the desktop's height. This allows for easy and stable adjustments.

Problems solved by technology

However, in operation, a height of one of two sides of the desk is adjusted first, and then a height of the other of the two sides of the desk is adjusted or two heights of the two sides of the desk are adjusted simultaneously by two people, thus adjusting the height of the desk troublesomely.
But the two hydraulic cylinders cannot be operated exactly and simultaneously to cause an inclination of a desktop.
Furthermore, each hydraulic cylinder is manufactured at a high cost.

Abstract

A height adjusting structure for a desk is applied to adjust a height of a desktop which is connected with two first supporting tubes fitted with two second supporting tubes and contains: a through hole defined adjacent to a top end of each second supporting tube to expose each first supporting tube fitted in each second supporting tube; two adjustors arranged adjacent to two top ends of the two second supporting tubes. Preferably, one of the two adjustors has a swing lever disposed thereon to drive a driving gear and has a driven gear driven by the driving gear, and the other of the two adjustors has a driven gear fixed therein and simultaneously rotating with the driven gear of one of the two adjustors through a connecting rod.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a height adjusting structure for a desk in which at least one driven gear of at least one adjustor is driven by a driving gear to simultaneously rotate through a connecting rod, and then the at least one driven gear movably engages with at least one toothed section of the at least one first supporting tube, thus adjusting a height of a desktop easily and stably.BACKGROUND OF THE INVENTION[0002]A conventional fixed desk cannot be adjusted its height, so an adjustable desk has been developed. The adjustable desk contains two first supporting tubes, two second supporting tubes fitted with the two first supporting tubes, and two forcing bolts or two locking elements, wherein each of the two first supporting tubes has a plurality of positioning holes defined thereon so that one of the two forcing bolts or the two locking elements is inserted into one of the plurality of positioning holes to fix each first supporting tube and ea...
