Description
Technical field
The utility model is related to display lifting support technical field, more particularly, to a kind of ultra-thin lifting support.
Background technology
At present, various displays are widely used in living now, current display substantially using liquid crystal display as
Main flow, liquid crystal display is a kind of display of approximate tabular, and itself can not voluntarily stand, it is necessary to be lifted by support frame etc.
The support of support could be used, and to be more convenient to use in actual use, big multi-display also needs to lift, common now to use
To carry the lifting support of display in order to reach liftable function, the gearing machine of correlation can be provided with lifting support more
The adjustment of structure, the specifically adjustable height is realized by using that can balance the lifting module of display gravity in support frame
, and lift in the support longitudinal channels that module need to be vertically provided on tabular pedestal by stretching into and along liftable above and below support
Slide, and be that lifting is smooth, slide rail need to be also set in support, can rely on and risen along the guiding of slide rail to lift module
Drop.
Its support of prior art is from cross section, and appearance and size is very big, causes outward appearance thick, does not meet current people's
Esthetic requirement, the design reasons for also having lifting module among these, its lifting carriage part lifted in module compares for left and right directions
Roomy frame structure, the structure both sides have both wings separately, are connected respectively with two slide rails, it is clear that because of its framework and both wings
Structure and support left and right directions width is followed increasing.(its rail structure, which is removed, includes several rollings to ball-type slide rail also used
Outside pearl, in addition to outer rail, interior rail and pearl frame, its transverse shape is all approximately U-shaped), but its must two one slide rails combine and make
With, and obviously then waist occupies many bulks to two slide rails, it is impossible to the slimming of support is realized, whole slide rail is caused in support
Thickness is big on left and right directions, and then causing support, thickness is also and then big this side up, will so that slim support can not have been met
In the lifting support frame asked.
Utility model content
The purpose of this utility model is to provide a kind of ultra-thin lifting support, stupid to solve structure present in prior art

The bracing force of setting, and the lifting travel of setting is realized, the width of constant force wind spring 40 can not be made thin, its reel portion 41
Diameter can not be made small so that greatly limit lifting support (column) ultrathin development.
And the utility model is then broken through completely by the way that some or all of reel portion 41 are arranged on outside guide groove 21
The limitation of the specification of constant force wind spring 40 so that the thickness of lifting support, i.e., the thickness of board-like column 20 surmounted constant force wind spring 40
Limitation, it is possible to achieve its ultrathin development need.In the prior art, it is strong by constant force wind spring 40 and board-like column 20 itself
The limitation of degree, the thickness of board-like column 20, which is discharged, is reduced to more than 6-7mm, and the utility model passes through outside the part of reel portion 41
Put, then the thickness of board-like column 20 can be reduced to below 4.9mm.
Further, since it is external by the part of reel portion 41, for accommodating the fluting space of constant force wind spring 40 significantly in column
Reduce, entity part ratio is greatly improved in column cross-section, in the case of thickness identical, pillar construction of the present utility model
Intensity is equally significantly better than support post of the prior art.
Reel portion 41 is at least partly external, can also be all external under particular case.In addition, during expansion, reel
The winding radius in portion 41 constantly reduces, and reel portion 41 can also be arranged on to develop into outside guide groove 21 by the part at initial stage and all be set
Put outside guide groove 21.
In the utility model, the length of run of the upper and lower ends of guide groove 21 in short transverse is defined as flute length；Before
Upwards, the distance of the opening's edge of guide groove 21 to the bottom of guide groove 21 is groove depth, and distance is groove between the side wall of left and right two at rear
It is wide.
The axis direction in reel portion 41 is less horizontal to be set and is substantially parallel to board-like column 20；That is reel portion 41
Axis direction is consistent or parallel with the groove width direction of guide groove 21.
Wherein, the width of guide groove 21 is slightly larger than the width of constant force wind spring 40.Preferably, the width of guide groove 21 is 2-
6mm。
Two L-type wing plates 35 are symmetrical set；Matching, left guiding groove 22a and right guiding groove 22b are also symmetrical
Set.
As shown in figure 5, left guiding groove 22a is arranged on left guide groove 21a left madial wall, right guiding groove 22b is arranged on
On right guide groove 21b Right Inboard wall.
As shown in fig. 7, left guiding groove 22a may also be arranged on left guide groove 21a Right Inboard wall, and right guiding groove 22b
On the left madial wall for being correspondingly arranged at right guide groove 21b.
As shown in fig. 6,1 is each provided between insertion plate 35b and the leading flank of guiding groove arranges preceding ball 36b；Insert plate 35b
Ball 36a after 1 row is provided between the trailing flank of guiding groove.On insertion plate 35b length direction, preceding ball 36 and rear rolling
Pearl 36 is staggered, rather than is oppositely arranged up and down, more ultra-thin so as to realize.
In the present embodiment, lifting seat is arranged on board-like column in the form of slide rail, wherein, in board-like column as outer
Slide rail sets guiding groove, and interior track portion is then undertaken by insertion plate, thus compared with prior art, can be made on thickness
It is thinner.
And the slide rail form can be the form of two row pearls；Wherein, insertion plate 35b is S types on horizontal plane, and original is existing
Some straight-plate-types are compared, and two row's balls are in a thickness direction closer to it is possible thereby to which that does is more ultra-thin.
As shown in figure 8, slide rail form can be the form of three row pearls；The insertion plate of L-type wing plate 35 and the front side of guiding groove
2 row balls 36 are each provided between face；1 row ball 36 is provided between the insertion plate of L-type wing plate 35 and the trailing flank of guiding groove.
Wherein, insertion plate 35b is W types on horizontal plane, the like, in this way during more multiple rows of pearl mode, insert plate
Waviness can be done.
Draw in addition, insertion plate 35b upper and lower ends are provided with for circulating rolling between preceding ball 36 and rear ball 36
Guide structure.
Preferably, multiple L-type wing plates 35 are laid in matrix form, and in the height direction, reel portion 41 is arranged on adjacent two
