Technical field

The utility model is related to one kind and (refers to liquid crystal type, including display, monitor, plate display for display Device, similarly hereinafter and display for short) lifting support frame, more particularly to backing thickness be thinned structure lifting support frame.

Background technology

The display screen of the electronic product such as PC and television set is the liquid crystal based on liquid crystal display on the market at present Display be a kind of flat display, because itself can not self uprights, and must by support frame mode will show Device is located at precalculated position.Display bracket is in addition to providing the function of support display, and majority must possess adjustment display The function of height and position, this requires what the lifting module for connecting display in display bracket can be in support frame substantially to erect Lifted into the column or support of setting, and the lifting moving for lifting module is smooth, because ball sliding rail has action Smooth, stabilized structure, durable, movement parts gap is small, the advantages of rock small, therefore is widely used in display lifting support frame In and vertical support installed therein in be used as lift module lifting when support (slide rail is generally used in a pair, mutually Abreast vertically it is mounted near the both sides in display bracket medium-height trestle).Certainly, to make aobvious with greater weight Operate light when showing device lifting, must also there is one can balance the power source of display weight component in support frame, fixed force spring is because of power Value is constant, and structure is extremely simple, compact, cost is low, and footprint is small during drawing work, and is widely adopted, fixed force spring two End is located at support with lifting on module 6a (or interior rail in slide rail, be connected because lifting module with interior rail).

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 hair Open up history very long, 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, is plate body shape, is generally vertically arranged on base, its side has been recessed a storage tank；

Two slide rails, the both sides being respectively arranged in parallel to each other in the storage tank simultaneously are fixed on to form the storage tank On wall；

One lifting module 6a, including a sliding part 61a, a screen pitching hinge unit, shield itself rotation hinge unit, a company Connect the screen connecting plate of display；Sliding part both sides described in two correspond to slide rail described in two 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 the sliding part 61a is slided downwards along the two slide rails guide path, the fixed force spring 8a is corresponding Stretch and keep elastic pulling force constant for balance display gravity, make display can be arbitrarily with the height position required for being parked in Put；

Further to adjust the visual angle of display, what support 7a bottoms had 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, with a groove portion 21a and a connecting portion 22a, groove portion 21a is plate body shape and is 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 The sliding part 61a in lifting module 6a in connection display bracket.

Two row balls (ball 3a is steel ball) and a corresponding pearl frame 4a, 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, is accommodated and is held in the corresponding two row receiving hole of corresponding pearl frame 4a；Groove portion Each clamping common respectively contradicts a row ball 3a between the two sides of 21a plate bodys and two neighbouring raceway plate 11a；And interior rail 2a with Outer rail 1a be equipped with the face contacted with each ball 3a corresponding groove-like ball guiding and load raceway it is (each 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 slide rail).

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

But the ball slide rail in the slim support frame of prior art is two row balls and arrangement is contraposition arrangement, i.e., from slide rail Cross section sees that the ball arrangement of two row balls is (assuming that two row balls just respectively have a ball fortune in the slide rail in the prior art Move on the cross section) be：The line of centres of its two ball is along (the thickness direction industry definition of slide rail of slide rail thickness direction For generally perpendicular to the direction of the raceway plate plate face of outer rail two), namely " contraposition " arrangement that ball be referred to as in the industry is arranged is (accordingly We can also tilt on the cross section to the normal direction in the face of the line of centres by two row balls with the slide rail thickness direction The ball arrangement referred to as " dislocation " of one angle is arranged, the slide rail of certain currently available technology there is not yet such a dislocation is arranged, because As two row balls be in dislocation arrangement if in rail 2a will can not be positioned in outer rail, it is stabilized).So that the gross thickness of slide rail For：Locate the interior rail 2a plate bodys between the row ball of diameter+two of the outer rail 1a two raceway plate 11a row ball of thickness+two most Small thickness；Obviously can be still thicker.

The main bottleneck of the slimming of support frame is except there is the arrangement of fixed force spring in slide rail thickness, and in the prior art The winding axis general horizontal of the winder of fixed force spring and parallel to the publicly-owned face where two slide rail, and winder Because being that spring stalloy winding is formed, the diameter of its profile lifting the life requirements of drawing numbers because being unable to very little, therefore Also into the thinned big bottleneck of second support, certainly, existing slide rail also has some other structural factor to hinder subtracting for support It is thin.

Therefore, prior art is limited to these structural factors, limits it in the Display support for having thinner slide rail requirement Use in frame.

Due to the progress of the electronic product such as display bracket mechanism design in recent years, people pursue the support of more and more thinner Outward appearance, therefore the purposes of prior art will be quite limited, it is impossible to suitable for more slim display bracket product. Therefore the improvement of backing thickness reduction how is carried out by existing structure, realize display lifting support of the production with thinner requirement Frame, it has also become one of industry important topic to be solved.

Refer to shown in Fig. 2 to Fig. 8, and emphatically referring to Fig. 7, a kind of three pearls column thin display support frame, its feature It is, including：

One support 7, substantially in elongated plate body shape (because slim, so generally plate body shape；Illustrate but do not limit with This, material and shaping are such as shaped using aluminium alloy compression casting, and bottom is provided with a big threading hole 75, is walked for cables such as displays Line), one lateral plates (are illustrated but are not so limited, according to the side plate face of support 7, big provided with a storage tank 71 being recessed Body position on the upper side is recessed to be formed to plate face thickness direction, and two vertical slots 74 are further opened with for aftermentioned on storage tank 71 described in this example Two connecting portions 22 cross therebetween), the support 7 generally vertically (often has low-angle pitch tilt, but substantially still Vertical setting) set and (be typically that should be arranged on base 9, but be used as independent-lifting module also according to support when needing 7 Substantially erect using without on base 9)；

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 towards), each of which slide rail 10 is included again：

One outer rail 1, including two plate faces it is adjacent, towards plate body shape raceway plate 11 (general parallel orientation between both, it is clear that its Between form a receiving space), one connects the disjunctor portion 12 for the two raceway plates 11 that are connected (for example but not limited to this respectively：Such as horizontal stroke Section see outer rail 1 it is overall be in approximate U-shaped, such as extend longitudinally side and form storage tank for accommodating the interior lifting moving of rail 2；Outside Its longitudinal two ends of rail 1 can set block, be deviate from the interior rail 2 for stopping mobile；The outer rail 1 can be by Steel Sheet；It is therein Disjunctor portion 12, illustrates but not limited to this, equivalent to the back cover section of outer rail 1U fonts, need to typically be set on face of this section along longitudinal direction Putting several screwed holes or open-work is used to be connected with the column in display lifting support frame or support 7；The two raceways plate 11 is lifted Example is said but not limited to this, and two sections that back cover section is left behind are removed equivalent to outer rail 1U fonts)；Raceway plate 11 described in two towards Respective side it is upper (two sides general parallel orientation), along longitudinal direction provided with two phases on the side of one of them raceway plate 11 Between (have certain distance each other) and the ball 3 of parallel (obvious two raceway should along longitudinal direction should be parallel) contradicts the rolling of rolling Then contradict raceway and rolling of rolling on road, the side of another raceway plate 11 provided with a ball 3 along longitudinal direction In the medium position generally corresponded between raceway described in another two, (equivalent to three raceways are substantially in point of isosceles triangle in road Cloth)；

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, with a raceway The connecting portion 22 (connecting portion 22 is attached for such as lifting module 6 with the part on display lifting support frame) of portion 21 and one, From slide rail cross section, the groove portion 21 is in plate body shape and is arranged at (being substantially most of be arranged at) two rolling Between guidance tape 11 (groove portion 21 is arranged between the two raceways plate 11, simply substantially, such as be mostly in therebetween) and Keep gap (being touched because there is relative motion mutually to wipe between the two, so there should be gap) everywhere with the outer rail 1；The raceway The plate body two sides of portion 21 are respectively provided with corresponding at each raceway position of the respective neighbouring raceway plate 11 of correspondence (so interior rail 2 is corresponding with the respective three row raceway belonging to outer rail 1 and together constitutes three for the raceway of the conflict rolling of ball 3 The ball channel of row ball rolling, it is clear that it is in equilateral triangle that three passages of ball 3, which are substantially also, the passage of its certain drift angle Closely on the base where another two passage, it is clear that under certain condition, closer to base, slide rail thickness is smaller), the rolling (the obvious local sheets of face A where non-raceway in the two sides of local plate body of the road portion 21 at itself only one of which raceway One is face where raceway in two sides of body, and another is face A where non-raceway, such as the part referred in Fig. 2 at A arrows Face) it should be in the groove portion 21 having two bottom lands of two raceway of two raceways places side (because raceway is usually Occur in the form of shallow slot, there is groove then to have the raceway of groove depth and bottom land, such as the local arc-shaped slot suitable with the diameter of ball 3, Bottom land is its innermost position) line and one have between the rolling plate of two raceways (from the appearance, namely meaning The middle part local plate body of groove portion 21 and bent to the rolling plate side direction with two raceways and protruded, it is certainly convex enter Thickness direction of the direction substantially along slide rail, it is clear that under the conditions of certain limit, it is convex enter it is more, equivalent to ball misplace arrange More very, slide rail thickness is smaller, certainly, and face where described non-raceway, which convex can not be entered, touches raceway plate；So, such as from groove portion The overall shape of its relative position each other of the raceway groove face shape of three row raceways on 21 plate bodys appears as W shape waveforms Bending, this obviously can reduce slide rail thickness)；

Three rows of balls and corresponding elongated pearl frame 4, are separately positioned on corresponding with three row of the outer rail 1 by the interior rail 2 (form the passage of ball 3 in the three rows of balls passage that raceway is collectively forming and clamp each ball of conflict jointly)；Each equal edge of row ball Slide rail longitudinal direction is arranged, and each column ball includes the (ball of each ball 3 in a plurality of balls 3, each column ball 3 such as use steel ball) it is spaced, accommodates and be held in the corresponding receiving hole of the corresponding pearl frame 4 (the such as structure of pearl frame 4 The strip stalloy of the receiving hole of the quantity of ball 3 in correspondence ball row is arranged for band one)；(raceway is rolled for ball 3 Guiding and carry the effect with dispersion force, it is to avoid and mitigate stress converge, while particularly can also make the interior rail The 2 relatively described positions of outer rail 1 are stable, will not slip off separation, what this will be appreciated that；Certainly it is save on interior rail 2 and outer rail 1 In one to two place's raceway, the position of the relatively described outer rail 1 of the interior rail 2 is determined, also because This, it is believed that the raceway groove depth of one to the two place raceway is that zero with Unify legislation, but at this moment interior rail 2 is relative with outer rail 1 after all Rigidity, the intensity of motion can decline, one to the two place stress also excessively concentrate on material surface a bit, it is bad, it is not recommended that adopt With)

The pearl frame 4 is provided with stopper section 5, is touched to be raised the interior rail 2 of motion, drives band and avoid voluntarily Slide (slide rail be for lifting, using when outer rail 1 be fixed on support, interior rail 2 then reciprocal lifting, the pearl frame 4 is also followed Reciprocal lifting, it is apparent that after more than 4 lifting of pearl frame, having asynchronous unavoidably in being rolled because of the self gravitation reason of pearl frame 4 and because of ball 3 Pearl frame 4 is dropped gradually downward etc. reason, namely repeatedly relative movement after the relatively described interior rail 2 of the pearl frame 4 degree of overlapping It can gradually decrease, 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 and outer rail 1 is same When the quantity of ball 3 supported, the work of influence slide rail such as moves rigidity, and display is possible to rock, unstable；Therefore, it is so-called to set Backstop, refers to do a stop configurations on the pearl frame 4, such as local stamped bumps, riveting, welding smallclothes, makes the stop configurations 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 by interior Rail 2 touches the stop configurations of pearl frame 4 and forces to drive pearl frame 4 to return original position, no again when rising to nearly peak every time As for gradually down dropping, the stop configurations are so-called stopper section)；

The interior rail 2 through the three rows of balls rolling and by ball channel be oriented to and can relatively described outer rail 1 carry out Straight line lifting moving (it is quite obvious natural result)；The respective outer rail 1 of two slide rail 10 is fixedly arranged on to be formed respectively On the wall of the storage tank 71；

(obviously, now seen along the thickness direction of slide rail, because three rows of balls dislocation arrange, such as with prior art on an equal basis in Rail, outer rail thickness of slab and in the case of waiting ball diameter, it is clear that the size that the dislocation of this ball is arranged in slide rail thickness direction can be obvious Reduce；Prior art be two row balls contraposition arrangement, as also want to be thinned and correct mistakes position arrangement if obviously in rail because that cannot support And can not holding position it is stable, and use three rows of balls dislocation arrangement that interior rail position obviously can be made to be supported and stabilized, Slide rail one also can be used alone in support frame；Individually see that the three rows of balls Heterogeneous Permutation is somewhat like isosceles triangle arrangement, slide rail Thickness is thinned what be will be appreciated that)

One lifting module 6, including a sliding part 61 (being grillage like members, such as stamping parts is combined or casting forming), One screen connecting plate 62 (be 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)；Rail 2 in described in corresponding two is respectively fixedly connected in the both sides of sliding part 61 (being generally in both sides) The connecting portion 22 (this example be the connecting portion 22 through the vertical slot 74 stretch out the support 7 it is outer after slided with described 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 above and below at least dividing Two rows set (such as this example point four rows, often arrange one, it is clear that but often arrange also more than one) (such as this example in the support 7 In the storage tank 71 of support 7), each fixed force spring 8 (being formed by elastic steel sheet winding) includes a winder 81 (the approximate hollow cylinder of profile) and a connection end 82, and the winder 81 winding axis substantially generally perpendicular to the branch The plate face of frame 7, 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 with it is described Sliding 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；As for winder 81 and the company of setting of support, Such as this example is used by the borehole jack in the middle of winder 81 in the fixing axle 72 of support 7, certain fixing axle 72 and winder 81 Between the sleeve pipe provided with plastic wear carry out dottle pin, the two sides of winder 81 also typically have plastic sheet, pad anti-attrition to separate pad)； When the sliding part 61 is moved downwards together with the interior rail 2, each fixed force spring 8 by phase strain stretch and keeps bullet Property 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 and can substantially put down Weigh the gravity of display, display is realized in any height and position with stopping, can also be in lifting travel certainly in practical structures Inside set a friction pair to produce extra frictional resistance, position more steady, the descending operation feel for stopping display is more preferable).

Above please simultaneously emphatically referring to Fig. 7.

Further, it is please simultaneously (in figure for the sake of prominent, omitting interior rail 2) shown in Figure 3 emphatically, the stopper section 5 are connected by a hyphen plate 51 (such as, using harder short steel plate strip) and are formed with the upper top of three pearl framves 4 respectively (it is such as but not limited to this：Interval sets three holes of rivet 52 in short steel plate strip, and the upper top of corresponding three pearl framves 4 is also opened up Corresponding rivet hole, is then connected with rivet 52, and also can substitute rivet 52 with welding such as spot welding certainly is connected), when described interior Rail 2 can touch the transverse slat 51 when rising and drive the pearl frame 4 to follow upwards, it is to avoid because pearl frame 4 is back and forth lifted repeatedly and certainly Row gradually falls, while not influenceing the reciprocal elevating movement of the pearl frame 4 again.(this stopper section structure reliably, stably, simply, hold Easily realize, three pearl frame synchronisms are good).

Further, it is please simultaneously (in figure for the sake of prominent, omitting interior rail 2) shown in Figure 4 emphatically, the stopper section 5 are respectively equipped with one and convex to form and (are such as but not limited to this for top on the pearl frame 4 of the three rows of balls：Using at three Top respectively opens up a rivet hole on pearl frame 4, then naturally constitutes projection with the grade rivet clasp of rivet 53, notes after the riveting of rivet 53, with The two sides of pearl frame 4 see, the material distribution of rivet should be more some more than the material away from interior trackside in inner trackside, so as to convex more than material Rise can rail in backstop, while do not influence to lift in the raceway of outer rail 1 again；For another example, if pearl frame 4 is using can be if plastics integral pieces Thereon top in the lump the convex structure of integrated injection molding one formation stopper section 5；Obviously, similar bulge-structure can have a variety of variants； Noting the raised shape can touch on interior rail 2 top to block to guarantee in the raceway of outer rail 1 lifting carriage simultaneously Without being bypassed), raised can be touched when the interior rail 2 rises by the interior rail 2 and drive the pearl frame 4 and then to On, it is to avoid because of pearl frame 4, back and forth lifting repeatedly and is voluntarily gradually fallen, while not influenceing reciprocal elevating movement (this of the pearl frame 4 again Kind stopper section is simple in construction, easy realization, but three pearl framves go up and down with different paces and determine synchronization).
