Description

A kind of ultra-fine slender type supporting rack

Technical field

The utility model is related to display bracket technical field, more particularly, to a kind of ultra-fine slender type supporting rack.

Background technology

At present, various displays are widely used in living now, at present display substantially using liquid crystal display as Mainstream, liquid crystal display are a kind of display of approximate plate, itself can not voluntarily stand, it is necessary to by supports such as supporting racks The support of device could use, and to be more convenient to use in actual use.

Big multi-display also needs to lift, common now carrying the support device of display to reach liftable Function, can mostly be provided with relevant interlinked mechanism in support device, the adjustment of the specifically adjustable height be by using The lifting module of display gravity can be balanced in supporting rack to realize, and lift module need to be by stretching into vertically arranged column It is slided in longitudinal channels and along liftable above and below column, and is that lifting is smooth, slide need to be also set in column, to lift mould Group can be relied on and lifted along the guiding of slide.

Since display is heavier, its gravity need to be balanced, enable that lifting is laborsaving and display in arbitrary height with stopping, Just personnel is facilitated to use, and be all using fixed force spring for generating most of element of equilibrant force, this spring was stretching Its pulling force substantially constant during journey, display balance that can be preferably constant with gravity match, height of display position when realizing lifting It puts with stopping.Certainly want energy practical application that need to also connect the mechanism that can adjust display viewing angles in the part of the overhanging column of lifters Deng.Though above-mentioned these can meet it is basic operate with requirement, with the development of technology and the variation of people's aesthetical interest, At present people increasingly pursue that column is slender or leptosomatic display lifting support frame (so-called column is slender or slender type, Refer to from size all very littles of all directions of its shape in terms of the cross section of column), this is very big choose to traditional lifting support frame War, it is difficult to realize.

But the prior art is using traditional structure, i.e., because column inner space will install fixed force spring, and fixed force spring It is that cannot be made very small that appearance and size, which will carry certain display weight,.In addition, the rolling of lifting is also used inside column Pearl slide, and the appearance and size of ball slide rail is also because that will carry certain load and cannot be too small.These all will in column It is subject to greatly application limitation when asking further slender.

In this way, prior art column, from cross section, appearance and size is very big, causes appearance coarse, do not met column The user of slender demand needs and the esthetic requirement of current people.For this purpose, it proposes a kind of design rationally and effectively solves above-mentioned The column of defect and its corresponding supporting rack, in this industry great demand and development potentiality.
