Abstract

The invention herein relates to a foot stand structure of an adjustable computer desk, more especially, a foot stand structure of an adjustable computer capable of performing high efficient adjustment for desk body such as those used for placing the computer on it during operation; the structure not only efficiently and precisely adjusts the height of the computer desk, but also surpasses the inconvenience caused by the necessary disassembly of the foot stand of the prior computer desk for adjusting the height; the entire structure of the invention herein comprises of the adjusting frame seats, a link shaft rod, a set of inner rods with helical teeth and the matching threaded bushes, a set of smooth inner rods and bushes, a foot stand and an external rotating handle bar; furthermore, through the movement of the adjusting frame seats, the invention herein can efficiently adjust the foot stand of the computer desk, the computer desk as well as the computer to a satisfactory height for the user to achieve the efficient creativity of the entire disposition.

Claims

1. The invention herein relates to a foot stand structure of an adjustable computer desk, mainly comprising of a foot stand mounted by a set of threaded bushes thereon, the threaded bushes disposed by a set of inner rods with helical teeth capable of extending just and helically inside the threaded bushes, the inner rods with helical teeth extending respectively upwards and inserted into the inner space of an adjusting frame seat, a link shaft rod connecting the link between the two transverse adjusting frame seats, and an external rotating handle bar, is characterized that:

the foot stand has a set of threaded bushes and a set of inner rods with helical teeth capable of extending just and helically inside the threaded bushes mounted on one side surface of the longitudinal sides of the foot stand, another set of relative and smooth bushes and inner rods mounted on the other side surface of the longitudinal sides, a transverse extension rod connecting both the inner rods with helical teeth with the adjusting frame seats thereon and the smooth inner rods, and a powerful spring mounted on the bottom portion inside the smooth bushes;

the threaded bushes have a set of inner rods with helical teeth capable of extending just and helically inside the threaded bushes;

the threads are formed on the inner side surfaces of the threaded bushes;

the sizes and the forms of the helical teeth on the column surfaces of the inner rods with helical teeth just match with the threaded threads;

the adjusting frame seat comprises of a shell body, one vertical and one horizontal bevel gears in mesh and mounted therein;

the central portion of the vertical bevel gear is penetrated to respectively connect with both the link shaft rod in the front and at the rear portions and the external rotating handle bar approximately at the central area of the penetrated portion;

the link shaft rod connects the central portion of another vertical bevel gear disposed in the adjusting frame seat on the top end of the inner rod with helical teeth;

the horizontal bevel gear extends from the inner portion to connect with the inner rod with helical teeth;
