Description

A kind of lifting structure of extrusion forming

Technical field

The utility model is related to lifting support technical field, more particularly, to a kind of lifting structure of extrusion forming.

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.

People pursue that lifting column is ultra-fine or ultrathin during, the different degrees of underground of mechanical property of column Drop；Especially, in the prior art, in order to which lifters are mounted in the sliding slot in column, perforation is opened up on front side of sliding slot The strip shape gob at top, out of the insertion of the top of column sliding slot, the outboard end of lifters stretches out to connect lifters from strip shape gob Display.

Strip shape gob at the top of the perforation so that column is C fonts in the cross section at top, is caused under itself rigidity, intensity There are many drop, and the stable degree of support is not high.

Utility model content

It is in the prior art to solve the purpose of this utility model is to provide a kind of lifting structure of extrusion forming Lifting column need to open up the strip shape gob at perforation top so that column is C fonts in the cross section at top, causes itself rigid, strong The technical issues of degree declines very much, and the stable degree of support is not high.
