Varied widely as the development of technology is particularly people's aesthetical interest at present, increasingly require display liter The more slimming (the mainly slimming of its medium-height trestle, it is desirable in long and flat plate body shape) of descending branch support, but support frame is sent out Open up that history is very long, and several generations is thinned, then enter one be thinned will be extremely difficult, the existing skill closest with the utility model at present Its construction of the thin display lifting support frame of art approximately as (refer to Fig. 9,1 shown in), including：

The base of one plate body shape；

One support 7a, it is plate body shape, is generally vertically arranged on base, its side has been recessed a storage tank；

Two slide rail 10a, the both sides being respectively arranged in parallel to each other in the storage tank simultaneously are fixed on to form described house On the wall of groove；

One lifting module 6a, including a sliding part 61a, a screen pitching hinge unit, shield itself rotation hinge unit, one connect Connect the screen connecting plate of display；The two sliding part both sides correspond to two slide rails respectively；Screen pitching hinge unit is used to adjust The pitching visual angle of display；Shield the rotation angle that itself rotation hinge unit is used to adjust display itself；

At least certain force spring 8a, each fixed force spring 8a include an a winder 81a and connection end 82a, and institute State winder 81a winding axis general horizontal and parallel to the publicly-owned face where the two slide rails 10a, the connection end 82a With winder the 81a company of the setting sliding part 61a (or on interior rail in slide rail 10a described below) and support 7a respectively；When described Sliding part 61a along the two slide rails guide path slide downwards when, the fixed force spring 8a kept by phase strain stretch elasticity Tensions constant is for balancing display gravity, to make display can be arbitrarily with being parked in required height and position；

Further to adjust the visual angle of display, support 7a bottoms some is additionally provided with support rotation hinge unit 91a.

Especially it is noted that slimming of slide rail 10a described in above-mentioned to support is critically important, in prior art, its is specific Include again：

One outer rail 1a, it is substantially u-shaped in terms of cross section, namely be connected including a disjunctor portion 12a with by disjunctor portion 12a Two general parallel orientations, adjacent tabular raceway plate 11a；The disjunctor portion 12a is generally the homonymy longitudinal edge of the two raceways plate 11a Integrally extension bending interconnection is formed and is connected with the both sides in the support 7a in display lifting support frame edge；

Rail 2a in one, there is a groove portion 21a and a connecting portion 22a, groove portion 21a to be plate body shape and be arranged at two rolling Gap is kept everywhere between guidance tape 11a and with outer rail 1a；By rolled portion 21a plate bodys, integrally curved prolong is formed the connecting portion 22a, is used In connecting the sliding part 61a in the lifting module 6a in display bracket.

Two row balls (ball 3a is steel ball) and pearl frame 4a corresponding to one, the pearl frame 4a are substantially in terms of slide rail cross section U-shaped, between the outer rail 1a and interior rail 2a, its opening direction and outer rail 1a opening direction is towards identical；Two row rollings Each ball 3a in pearl 3a is spaced, accommodate be held in corresponding in two row receiving holes corresponding to pearl frame 4a；Groove portion 21a Each clamping common respectively contradicts a row ball 3a between the two sides of plate body and two neighbouring raceway plate 11a；And interior rail 2a with it is outer Rail 1a is equipped with ball guiding and raceway (each cunning of load of corresponding groove-like on the face contacted with each ball 3a Two row raceways each affiliated are correspondingly formed the passage that two ball 3a are rolled jointly on the interior rail 1a and outer rail 2a of rail).

Thus, relatively moved between interior rail a2 and outer rail 1a by ball a3 rolling, make display bracket Module is lifted by the guiding of ball slide rail raceway and along a straight line path shift reciprocately.

Refer to shown in Fig. 2-8, present embodiments provide a kind of three pearl column display brackets, it includes：

The base 9 of one plate body shape, on working face；

One support 7, substantially in elongated plate body shape (because slim, so generally plate body shape；Illustrate but it is unlimited with This, material and shaping are such as shaped using aluminium alloy compression casting, and bottom is provided with a big threading hole 75 and walked for cables such as displays Line), and be generally vertically arranged on the base 9, the support its be provided with and be recessed towards the plate face of display side A storage tank 71, the bottom surface of the storage tank 71 offers two vertical, long vertical slots 74；(described in this example on storage tank 71 Two vertical slots 74 are crossed therebetween for the two described later connecting portions 22)；

Two slide rails 10, (two slide rails 10 are parallel to each other and are spaced for the both sides being abreast respectively arranged in the storage tank 71 Certain distance, such as, the general opening of two slide rail 10 mutually towards), each of which slide rail 10 includes again：

One outer rail 1, including two general parallel orientations, it is adjacent set plate body shape raceway plate 11 (general parallel orientation between two raceway plates 11, together When its between a receiving space is formed because alternate), one respectively connect be connected two raceway plates 11 disjunctor portion 12 (for example but Not limited to this：For example outer rail 1 is overall is in approximate U-shaped in terms of cross section, disjunctor portion 12 therein, equivalent to the back cover of U-shaped Section, the two raceways plate 11 then remove be left behind two sections of back cover section equivalent to U-shaped；The outer rail 1 can integrally be rushed by steel plate Pressing formation；Typically disjunctor portion along longitudinal direction face along set several screwed holes or open-work be used for in display lifting support frame Column or support 7 are connected；Its longitudinal both ends of outer rail 1 can set up block, be deviate from the interior rail 2 for stopping mobile)；

Rail 2 (being such as but not limited to this, can be integrally formed by steel plate punched or ferrous based powder metallurgical) in one, have one substantially In the connecting portion 22 of groove portion 21 and one of plate body shape, (connecting portion 22 is used to such as lift module with the part on display lifting support frame 6 etc. are attached), the groove portion 21 is arranged between the two raceway plates 11 that (groove portion 21 can be that it is mostly in Between it) and keep gap (to be touched because there is relative motion mutually to wipe between the two, so between should having everywhere with the outer rail 1 Gap)；A part for the connecting portion 22 is passed through the vertical slot 74 and stretched out outside support 7；

Three rows of balls and corresponding elongated pearl frame 4, each row ball arrange along slide rail longitudinal direction, and each column ball wraps Include a plurality of balls 3 (ball 3 such as uses steel ball), each ball 3 in each column ball is spaced, is accommodated and is held in correspondingly The pearl frame 4 (be such as but not limited to, the structure of pearl frame 4 is the receiving hole of the quantity of ball 3 in the corresponding ball row of the row of band one Strip stalloy, but the pearl frame in Fig. 7 be three sides of pearl frame 4 be connected, be pearl frame structure one kind) on correspond to number In the receiving hole of amount；From slide rail cross section, the centre of sphere of the three rows of balls substantially (adheres to three rows of balls separately in isosceles triangle 3 ball centre ofs sphere linked up with straight line see) arrangement, the one side of the plate body of groove portion 21 and a neighbouring raceway plate The common ball contradicted in isosceles triangle corner point (forms the rolling that common clamping contradicts the row ball between 11 plate faces Pearl roll channel), supported jointly between the another side of the plate body of groove portion 21 and neighbouring another plate face of raceway plate 11 (the another two balls rolling for forming the clamping conflict row ball jointly is logical in two balls of the base angle point of isosceles triangle two for synapsis Road)；

The average diameter that the height of the isosceles triangle is less than or equal to the three rows of balls adds 3mm's and value；That is, it is described etc. The height of lumbar triangle shape≤(average diameter+3mm of three ball)；

In terms of slide rail cross section, it is clear that under certain condition, isosceles triangle it is high smaller, it is meant that in corner point Ball 3 more to another two balls direction move, slide rail thickness is smaller, also implies that the middle part local plate body edge of groove portion 21 Slide rail thickness direction and more bent to isosceles triangle base side direction and protruded；So, with aligning arrangement using two row Prior art construction slide rail contrasts under the same conditions, slide rail thickness can be substantially reduced using three rows of balls dislocation arrangement, through reality Border shows, the change of dislocation arrangement size is carried out in this formula size section, can be more beneficial for reducing the chi of slide rail thickness direction Very little, processing technology is optimal；Slide rail can be made in the most thin (attention, as prior art two arranges rolling of thickness direction minimum, slide rail as far as possible Pearl contraposition arrangement also wants to be thinned and corrects mistakes position arrangement then due apparently to interior rail cannot get the support of triangle ball and can not holding position Stabilization is put, and uses three rows of balls dislocation arrangement interior rail position obviously can be made to be supported and stabilized, and slide rail one It can be used alone in support frame, what this will be appreciated that)；The pearl frame is provided with stopper section, to be raised motion The interior rail touches, drives band and avoid voluntarily sliding.

Slide rail is for lifting, and outer rail 1 is fixed on support during application, the then reciprocal lifting of interior rail 2, the pearl frame 4 And then reciprocal lifting, it is apparent that after more than 4 lifting of pearl frame, have unavoidably not in being rolled because of the self gravitation reason of pearl frame 4 and because of ball 3 The reason such as synchronous and pearl frame 4 is dropped gradually downward, namely repeatedly after relative movement the relatively described interior rail 2 of the pearl frame 4 weight Folded degree can be gradually decreased, and at this moment participating in rolling the total quantity of ball 3 of work will accordingly be reduced, so as to reduce interior rail 2 with it is outer Rigidity is such as moved in the quantity of ball 3 supported simultaneously of rail 1, the work for influenceing slide rail, and display is possible to rock, is unstable；Therefore, institute Meaning sets backstop, refers to do a stop configurations on the pearl frame 4, such as local stamped bumps, riveting, welding smallclothes, makes the backstop Structure interior rail 2 rise movement nearly peak position on can be touched by interior rail 2 gear and be forced drive band it is together upward, i.e., it is to borrow The stop configurations of pearl frame 4 are touched when helping interior rail 2 to rise to nearly peak every time and force to drive pearl frame 4 to return original position again Put, be unlikely to gradually down to drop, the stop configurations are so-called stopper section.

The groove portion plate face and the two raceway plate plate faces are distinguished on the correspondence position contradicted with the three rows of balls Being provided with ball along longitudinal direction, (raceway is usually to occur in the form of shallow slot, such as the part suitable with the diameter of ball 3 with raceway The raceway of arc-shaped slot；Raceway, which is used for the guiding that ball 3 rolls, makes the relatively described position of outer rail 1 of the interior rail 2 stable, will not slide Open separation, while can also carry the effect with dispersion force, when ball 3 and the raceway groove plane-plane contact, avoid and mitigate by Power is concentrated on face a bit, improves contact stiffness and service life, what this will be appreciated that；Certainly in interior rail 2 with being saved on outer rail 1 But the wherein special a certain position that may still enable the relatively described outer rail 1 of the interior rail 2 to raceway at two determines, but after all At this moment interior rail 2 and rigidity, the intensity of the relative motion of outer rail 1 can decline, and one to the two place stress also excessively concentrates on material surface A bit, it is bad, it is not recommended that use, be Unify legislation, it is believed that the track groove of one to the two place raceway still has simply also therefore Zero) depth is approximately；

The interior rail 2 can carry out reciprocating linear movement through the rolling and guiding of the three rows of balls relative to the outer rail 1 (it is quite obvious natural result)；

The respective outer rail 1 of two slide rail 10 is fixedly arranged on to be formed on the wall of the storage tank 71 respectively；

One lifting module 6, including a sliding part 61 (for grillage like members, for example stamping parts combines or casting forming), One screen connecting plate 62 (for plate-like piece, such as steel stamping part, for connecting display screen, general lower edges be additionally provided with clamp with Just fast dismounting display use is realized)；The corresponding two interior rails 2 are respectively fixedly connected in the both sides of sliding part 61 (being generally in both sides) The connecting portion 22 (this example is the connecting portion 22 stretched out through the vertical slot 74 outside the support 7 after with the slip Part 61 is connected, the sliding part 61 puts in support 7 with its effect that is connected and is also in turn, visual concrete structure which kind of It is more convenient, more meets the requirements and select)；

At least two (such as this example be 4) fixed force springs 8 (pulling force approximately constant when it is stretched) and at least divide up and down Two rows set (such as this example point four rows up and down, often arrange one, it is clear that but often arrange also more than one) in the support 7 (such as This example is in the storage tank 71 of support 7), and at least one fixed force spring (for example this example is 4, then wherein at least Should have one) itself be two to three layers of similar elastic steel sheet be brought into close contact it is compound together winding into (by similar two to Three layers of elastic steel sheet be brought into close contact it is overlapping it is compound together, equivalent to one steel disc, together winding form, often enclose tight from each other Patch, so that it increases unobvious in general shape but spring tension is accordingly into multiple increase, although note that this internal structure Fixed force spring is quantitatively still considered as a fixed force spring), each fixed force spring 8 (being formed by elastic steel sheet winding) includes One winder 81 (one hollow cylinder of profile approximation) and a connection end 82, and the winding axis of the winder 81 substantially hangs down Directly in the support 7 plate face (winding axis so selection after, size of the fixed force spring on the direction of backing thickness can Greatly reduce, certain fixed force spring 8 reduces the elastic force for single spring in the backing thickness direction size to be declined, but can be again Accelerated by multiple rows of up and down to make total spring force meet to require, final such arrangement is than prior art significantly Size of the fixed force spring on backing thickness direction is reduced, while still meets total force value requirement, so as to realize support 7 It is ultra-thin), the winder 81 and connection end 82 respectively the company's of setting support 7 and the interior rail 2 (due to interior rail 2 and the cunning Moving part 61 is connected, and therefore, the connection end 82 is also attached to the portion that the sliding support 61 is stretched into the support 7 Point, it is clear that effect is suitable, specifically mainly considers that connection is more convenient reasonable；Table during as winder 81 due to its work Face can opposite brackets 7 rotate, therefore company of setting of itself and support can select according to concrete structure, for example this example is using by winder 81 Between borehole jack mounted in support 7 fixing axle 72 on, between certain fixing axle 72 and winder 81 be provided with plastic wear sleeve pipe Carry out dottle pin, the two sides of winder 81 are also typically provided pad that plastic sheet etc. separates etc. and carry out anti-attrition and prevent from scratching support 7)；When the sliding part 61 moves downwards together with the interior rail 2, each fixed force spring 8 by phase strain stretch and is protected Holding elastic pulling force, (its pulling force still keeps approximately constant when fixed force spring is stretched, and the power of each fixed force spring is added can The gravity of display is substantially balanced, display is realized in any height and position with stopping, can also risen certainly in practical structures Set a friction pair in drop stroke to produce extra frictional resistance, make the position that display stops is more steady, descending operation feel more It is good).

Above please simultaneously emphatically referring to Fig. 7 and Fig. 2.
