Abstract

The invention relates to an adjustable lifting shore device which comprises a base, a cylinder, at least one contacting unit, an axle rod and a supporting frame. The cylinder is fixed on the base. At least one groove is formed on an inner surface of the cylinder along the first axle. Each contacting unit is corresponding with one of the grooves and comprises a flexure overhang member locating to the first axle direction. One end of the axle rod is inserted into the cylinder. It provides at least one dental plate on an external surface of the axle rod along to the second axle direction. The up and down of the supporting frame fixed on the axle rod forces a force on the supporting frame, so that each dental plate and the flexure overhang member of the corresponding contact unit can do relative movement to adjust the height of the supporting frame.

Description

technical field

[0001] The present invention relates to an adjustable lifting support apparatus (Adjustable lift support apparatus), in particular to an adjustable lift support apparatus which can avoid function failure due to long-term use. Background technique

[0002] Recently, flat panel displays have become more and more popular, and have gradually replaced projection devices and cathode ray tube displays (Cathode ray tube displays, CRT displays). A flat panel display, such as a liquid crystal display (LCD), is usually installed on a lifting device so that it can be raised or lowered.

[0003] In actual use, it is desirable to be able to adjust the height of the flat-panel display to the most suitable viewing position. At present, there are various existing technologies about the lifting device being used, such as a mechanism using a ball slide rail with a constant force spring, a mechanism using a connecting rod with a spring, or other similar mechanisms. Since the t...
