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 lifting module for requiring to connect display in display bracket can be lifted.
Act smooth because ball sliding rail has, stabilized structure, durable, movement parts gap is small, the advantages of rock small, because
(usual prior art slide rail is into one for this support for being widely used when being used as lifting module lifting in display lifting support frame
To using, on the both sides in the support of placement, because the support in display bracket is generally vertical, therefore in installation settings support
Slide rail it is also and then generally vertical, notice that support majority is provided on base, therefore, support have can respect thereto around big
Body plumb line rotate, have then can around base top (having a protuberance protruded upward on base) horizontal axis slightly pitching
Rotation certain low-angle, but substantially or vertical direction).But people's aesthetical interest is varied widely at present, increasingly
It is required that the more slimming of display lifting support frame, and the bottleneck being thinned is being thinned for the thickness of slide rail, but slide rail is sent out
Open up history very long, thinned several wheels, and rail structure part is few, then enter one it is thinned will be extremely difficult, in currently available technology
Its most thin slim slide rail of the ball slide rail used in display lifting support frame is double row ball contraposition arrangement and interior rail is plate
Build, be closest with the utility model, it is constructed approximately as (shown in Figure 1), including:
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 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 straight, flat board plate body shape and sets
It is placed between two raceways plate 11a and keeps gap everywhere with outer rail 1a;The connecting portion 22a is integrally extended by rolled portion plate body
Formed, for connecting the lifting module 6a in display bracket.
Two row balls (ball 3a is steel ball), and pearl frame a 4a, the pearl frame 4a are substantially in U-shaped in terms of slide rail cross section
Shape, it is arranged as opening direction setting identical with outer rail 1a opening direction in outer rail 1a;It is each in two row ball 3a
Ball 3a is spaced, is accommodated and is held in the corresponding two row receiving hole of corresponding pearl frame 4a;The two sides of groove portion 21a plate bodys
Each clamping respectively contradicts a row ball 3a between two neighbouring raceway plate 11a;And interior rail 2a and outer rail 1a with each ball 3a
Be equipped with the face of contact the ball 3a guidings of corresponding groove-like and equal loads raceway (the interior rail 1a of each slide rail with it is outer
Two row raceways each affiliated are correspondingly formed the passage that two ball 3a are rolled jointly on rail 2a).
Known industry is defined as to the thickness direction of slide rail generally perpendicular to two raceway plate 11a direction, the prior art
Slide rail in terms of the cross section of slide rail, the arrangement of its two row ball is:It passes through the faces of all ball 3a lines of centres of two row balls
Normal direction it is vertical with the thickness direction namely be referred to as in the industry ball row " contraposition " arrange (we are at this accordingly
On cross section can also an angle be tilted to the normal direction and the slide rail thickness direction in the face of the line of centres by two row balls
Ball arrangement referred to as " dislocation " is arranged, and certain currently available technology is there is not yet such a dislocation is arranged, because such as two row balls are in
Then interior rail 2a will fall over and can not be positioned, fix for dislocation arrangement).
Thus, relatively moved between interior rail a2 and outer rail 1a by way of ball a3 rolling, alleviate both
Moving resistance, makes the lifting module of display bracket can be reciprocal along a straight line path by the guiding of the ball slide rail raceway
Displacement.
But also just because of the arrangement of the row ball of ball slide rail two of prior art is seen as contraposition arrangement from slide rail cross section,
Be limited to this structural factor so that the gross thickness of slide rail for outer rail 1a two raceway plate 11a the row ball of thickness+two diameter+
Locate the minimum thickness of the interior rail 2a plate bodys between two row balls, can be still thicker, limiting it is having thinner slide rail requirement
Display bracket in use.Meanwhile, if individually seeing the rail structure, its interior rail 2a is not obviously by completely about
Beam, makes interior rail 2a be in a less firm position location, therefore, is also not suitable for rocking display the feelings for requiring very tight
Used under condition, the lifting of a single one slide rail can not be more used in support frame.
Due to the progress of the electronic product such as display bracket mechanism design in recent years, more and more products are pursued increasingly
Thin support outward appearance, therefore the purposes of the ball slide rail of prior art will be quite limited, it is impossible to suitable for more slim
In display bracket product structure.Therefore the improvement of slide rail thickness reduction how is carried out by existing structure, make existing ball
Slide rail can be employed in the display bracket with thinner requirement, it has also become the industry important topic to be solved it
One.

Fig. 2 to Fig. 8 is referred to particularly shown in Fig. 2, a kind of distributed slim ball of the oblique parallelogram of four row ball is slided
Rail, is specially used as the ball slide rail (meaning that its application field is specific) in display lifting support frame medium-height trestle, comprising:
One outer rail 1, including two neighbours set and general parallel orientation plate body shape raceway plate 11 (general parallel orientation between two raceway plates 11,
A receiving space is formed because alternate between it simultaneously), the longitudinal edge of the homonymy of raceway plate 11 1 described in two is mutually curved to prolong interconnection
An integrally formed disjunctor portion 12 is (for example but not limited to this:It is in approximate U-shaped that outer rail 1 is overall i.e. in terms of cross section, therein
Disjunctor portion 12, equivalent to the back cover section of U-shaped, the two raceways plate 11 then removes back cover section is left behind two equivalent to U-shaped
Section;The outer rail 1 can be by steel plate integrated punching or rolling forming;It is general that several spiral shells are set along along longitudinal face in disjunctor portion 12
Pit or open-work are used to be connected with the column in display lifting support frame or support 7;Its longitudinal two ends of outer rail 1 can set up envelope
Gear, is 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, including one substantially
(groove portion 21 can be that it is mostly between it) between raceway plate 11 described in two is arranged in the groove portion 21 of plate body shape,
(connecting portion 22 is used with the connecting portion 22 extended by side longitudinal edge bent outward of the groove portion away from the disjunctor portion
It is attached in such as lifting module 6 with the part on display lifting support frame, several screwed holes or open-work can be set, its is specific
How it is curved extend be considered as with lifting module 6 physical fit to be connected), between the interior rail 2 and the outer rail 1 are kept everywhere
Gap (is touched, so should have gap) because there is relative motion mutually to wipe between the two;
Four row balls and corresponding elongated pearl frame 4, each row ball are arranged along slide rail longitudinal direction, each column ball
The each ball 3 included in a plurality of balls 3 (such as ball 3 uses steel ball), each column ball is spaced, accommodates guarantor
The corresponding pearl frame 4 is held in (to be such as but not limited to, the structure of pearl frame 4 is that band one arranges the quantity of ball 3 in correspondence ball row
The strip stalloy of receiving hole) on respective amount receiving hole in;From slide rail cross section, the plate body of groove portion 21
Two row balls being separated by are contradicted between raceway plate plate face described in one side and neighbouring one jointly (to form common clamping conflict to be somebody's turn to do
Two ball channels of row ball) and the line of centres of the centre of sphere of the two row ball is defined as the first line of centres, the groove portion 21
The another two row ball being separated by is contradicted between the another side of plate body and neighbouring another raceway plate plate face jointly (to form altogether
Another two ball channels of the row ball are contradicted with clamping) and the line of centres of the centre of sphere of the another two row ball be defined as second and connect with the heart
Line, first line of centres is parallel with second line of centres, and the line direction of the two-end-point of line of centres homonymy described in two is tilted
In the plate face of raceway plate 11 described in two (it means that:Between four ball centre ofs sphere adjacent connection lines form one can be referred to as tiltedly it is parallel
Quadrangle, it requires that an opposite side is parallel to each other, but failed call is isometric, and remaining another both sides are required without parallel, also requires, shows without isometric
So it may include isosceles trapezoid, and parallelogram is its special case, and another two line requires that inclination is to avoid two two
Row ball-shaped is arranged into contraposition, is vertical trapezoidal equivalent to avoiding the formation of as rectangle or one side of something, this will form ball contraposition and arrange
Cloth and slide rail can not be thinned), the distance between first line of centres and described second line of centres≤(four balls
Average diameter+3) (㎜) (that is, if four row ball diameters not wait if average diameter calculate) (in terms of slide rail cross section, it is clear that
Under certain condition, the distance of first line of centres and second line of centres is smaller, it is meant that on a line of centres
The ball 3 of two-end-point more draws close movement to another ball direction of line of centres two, namely slide rail thickness is smaller, also implies that groove portion
21 local plate body bending is about violent;So, with the prior art construction slide rail using two row contraposition arrangements under the same conditions
Contrast, slide rail thickness can be substantially reduced using the dislocation arrangement of four row balls, through actually showing, carried out in this formula size interval wrong
The change of position arrangement size, can be more beneficial for reducing the size of slide rail thickness direction, and processing technology is optimal;Slide rail can be made in thickness
Direction minimum, slide rail as far as possible is most thin) (note, such as row ball of prior art two contraposition arrangement also wants to be thinned and the position row that corrects mistakes
Cloth then due apparently to interior rail cannot get enough supports in ball arrangement and can not holding position it is stable, and use the dislocation of four row balls
Arrangement obviously can make interior rail position be supported and stabilized, and particularly only need an one slide rail to be used alone in support frame
In, this just brings many benefits, what this will be appreciated that);
The interior rail 2 can carry out reciprocating linear movement through the rolling and guiding of the four row ball relative to the outer rail 1
(it is quite obvious natural result).
Further, screw or open-work of the connecting portion 22 provided with connection (specifically should be with the lifting waits pair of module 6
The physical fit for the part that should be connected and selection);The pearl frame 4 be by steel plate punched is integrally formed or plastic injection piece one into
Shape.
Further, please simultaneously shown in Figure 5 emphatically, in terms of slide rail cross section, the outer rail 1 is divided into two L-shaped
Steel plateelement combination (can be so reduced on process for machining and manufacturing because of the difficulty of forming difficulty;Two L shaped plate parts can be steel plate punched or rolling
Pressing formation part), the long sides of two L-shaped corresponds to raceway plate 11 described in two respectively, and the short sides of two L-shaped is then overlapped and connected constitutes
(rivet can not be shown mutually with small rivet rivet clasp in figure by being connected, certainly also solderable in disjunctor portion 12;The connected short side equivalent to
Disjunctor portion 12), the two short sides overlapping of L-shaped part described in two is longitudinally arranged in connection display lifting support frame along slide rail
Support 7 screwed hole or through hole (riveting location of two L part short side overlappings it should be noted that its position should stagger).
Further, it is please simultaneously shown in Figure 6 emphatically, the vertical side of the edge phase of the pearl frame 4 of the four row ball
Mutually be connected as a single entity, make from gap that is u-shaped in terms of slide rail cross section and being arranged between the interior rail 2 and the outer rail 1 and
The opening direction of the U-shaped is in the position away from the disjunctor portion 12, and (this is that a kind of four pearl framves 4 link into an integrated entity formula
Structure, pearl frame semi-finals degree and rigidity can be a shade better, meanwhile, the synchronism that four pearl framves 4 are lifted is also quite a lot of;But from cross section,
Because four pearl framves 4 are linked to be a U-shaped, the certain interval width in gap between the periphery of interior rail 2 and outer rail 1 certainly will be tied up, accordingly
Ground is readily appreciated that slide rail thickness can increased).
Further, please simultaneously shown in Figure 7 emphatically, the two raceways plate 11 is separately fixed in display bracket
Support 7 left and right side channel internal face on, and (at this moment the disjunctor portion 12 of the outer rail 1 is then formed by local take into account of the support 7
Support 7 be to use metallic extrusion molding, inside reserves the corresponding longitudinal slot of the profile of two outer rail 1 with placement, at this moment obviously,
The structure of support 7 of two raceway plates 11 contact can play a part of disjunctor portion, so can be by partial display support frame medium-height trestle 7
The shape and strength and stiffness of itself, at this moment need to only process two raceway plates 11 and be arranged on the wall of support 7, it is possible to decrease material
Consumption, simplifies the structure of outer rail 1);The two raceways plate 11 is Steel Sheet.
Further, the disjunctor portion 12 is provided with the screwed hole or through hole of connection along longitudinal direction;The outer rail 1 and described interior
Rail 2 and the pearl frame 4 are formed for steel plate punched.
Further, raceway plate plate face described in the groove portion plate face and two is in the corresponding position contradicted with the four row ball
Put respectively along longitudinal direction provided with ball raceway (raceway be usually in the form of shallow slot occur, such as this example be and ball 3
The raceway of the suitable local arc-shaped slot of diameter, the guiding that raceway is used for the rolling of ball 3 makes the relatively described outer rail 1 of the interior rail 2
Position is stable, will not laterally slip off separation, meanwhile, ball 3 is contacted with face with the groove face of the raceway and can also carried with dispersion force
Effect, it is to avoid or mitigate stress and concentrate on face a bit, improve contact stiffness and service life, what this will be appreciated that;When
So being save on interior rail 2 and outer rail 1 wherein special a certain may still make the relatively described outer rail 1 of the interior rail 2 to raceway at two
Position determined that but at this moment interior rail 2 and rigidity, the intensity of the relative motion of outer rail 1 can decline after all, one to two place by
Power also excessively concentrate on material surface a bit, it is bad, it is not recommended that use, be Unify legislation, it is believed that this one to two also therefore
Place raceway raceway still have simply depth be approximately zero).
Further, 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 sliding (slide rail be for lifting, using when outer rail 1 be fixed in generally vertically arranged support, interior rail 2
Then reciprocal lifting, the pearl frame 4 also and then reciprocal lifting, it is apparent that after more than 4 lifting of pearl frame, because of the self gravitation reason of pearl frame 4
And pearl frame 4 is dropped gradually downward because there is the reason such as asynchronous in the rolling of ball 3 unavoidably, namely it is repeatedly described after relative movement
The degree of overlapping of the relatively described interior rail 2 of pearl frame 4 can be gradually decreased, and at this moment participating in rolling the total quantity of ball 3 of work will accordingly subtract
It is few, so as to reduce interior rail 2 with outer rail 1 while rigidity, display are such as moved in the quantity of ball 3 supported, the work of influence slide rail
Be possible to rock, it is unstable;Therefore, it is so-called to set backstop, refer to do a stop configurations on the pearl frame 4, such as local stamped bumps, riveting
Connect, weld smallclothes etc., make the stop configurations interior rail 2 rise movement nearly peak position on can be touched by interior rail 2 gear and it is strong
Make drive band together upward, certain stop configurations do not open too big again, energy smoothly descending in outer rail 1, i.e., it is by interior rail 2
The stop configurations of pearl frame 4 are touched when rising to nearly peak every time and force to drive pearl frame 4 return original position again, be unlikely to
Gradually down drop, the stop configurations are so-called stopper section).
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 four pearl framves 4 respectively
(it is such as but not limited to this:Interval sets four holes of rivet 52 in short steel plate strip, and the upper top of corresponding four 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 fall, while do not influence again the reciprocal elevating movement of the pearl frame 4 (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 backstop
Portion 5 is respectively equipped with one and convexed to form for top on the pearl frame 4 of the four row ball (is such as but not limited to this:Using four
Top respectively opens up a rivet hole on individual pearl frame 4, then naturally constitutes projection with the grade rivet clasp of rivet 53, notes after the riveting of rivet 53,
Seen with the two sides of pearl frame 4, the material distribution of rivet should be more some more than the material away from interior trackside in inner trackside, more than material
Projection can rail in backstop, while do not influence to lift in the raceway of outer rail 1 again;For another example, can if pearl frame 4 is using plastics integral pieces
The convex structure formation stopper section 5 on top thereon in the lump integrated injection molding one;Obviously, similar bulge-structure can have a variety of changes
Formula;Noting the raised shape can make top on interior rail 2 touch gear again simultaneously to guarantee the lifting carriage in the raceway of outer rail 1
Firmly without being bypassed), the projection can be touched by the interior rail 2 when the interior rail 2 rises and drive the pearl frame 4 to follow
Upwards, it is to avoid because of pearl frame 4, back and forth lifting repeatedly and is voluntarily gradually fallen, while not influenceing the reciprocal elevating movement of the pearl frame 4 again
(this stopper section is simple in construction, easy realization, but three pearl framves go up and down with different paces and determine synchronization).
It is noted that being related to the detailed implementation structure about pearl frame 4 in foregoing because more numerous and diverse, it is therefore necessary to herein
Illustrated in greater detail, but not limited to this in the lump:The function of pearl frame 4 is, is spaced multiple balls 3, accommodates and be maintained at each
Among corresponding receiving hole, do not drop, so that ball 3 is rotated freely, and will not make the generation of colliding each other of a plurality of balls 3 dry again
Relate to, so as to ensure that each column ball can be rolled along the ball guiding conduit of rail in slide rail 2 and outer rail 1.Therefore, illustrating but not limiting
In this, each receiving hole on the pearl frame 4 is slightly over the hole of the diameter of ball 3, and (it is straight that diameter is slightly greater than the ball 3
Footpath is preferably, it is clear that it is complete circle that its shape is not necessarily non-, as long as major part is circle), the side of each receiving hole
Edge on the plate face both sides of pearl frame 4 towards the ball surface of ball 3 accommodated, integrally detain by a pair of dots of bending extension, i.e. formation
Two clasp component (not shown) of ball 3 are held, two clasp components note that the substantial diametrical for being located at receiving hole should be separated here
Two-end-point on it is relatively good, and the diameter where the end points of two sides is preferably mutually vertical, preferably clasp to live ball 3
Sphere make that its is more stable, it is more smooth to rotate and is difficult to drop);The actual clasp component can maintain the operation principle of ball 3
Be, using the elasticity of the material itself of pearl frame 4, i.e., the micro-elastic produced using small clasp component partial by ball 3 slightly
Firmly with regard to that can be installed into receiving hole, at the same because after dress retainer elastic recovery can flexibly keep out the ball surface of ball 3 again and make it
No longer deviate from;This structure is more suitable for the pearl frame 4 being stamped and formed out.Certainly, as used the integrally formed pearl frame 4 of plastics, then should
The thickness of pearl frame 4 is actual preferably thicker than stamping parts, and the orifice edge diameter of the receiving hole two sides all slightly smaller than should
The sphere diameter of ball 3, forms the cavity for coating the ball 3 slightly, equivalent to being shaped inside hole by the sphere of the ball 3, so
It can realize that the ball 3 easily is loaded into the receiving hole ball 3 and will not then drop again because of the micro-elastic of material, also can be real
The purpose of existing clasp component.Certainly, in above-mentioned, the plate face of the pearl frame 4 only sets alternate in the diametric(al) of one side receiving hole
Every the also possible of, at least two clasp components, but now, the diameter in the hole is slightly smaller than steel ball size, it is clear that this
Shi Gangqiu can only be limited in a direction in receiving hole, and other direction is then free, though ball 3 can fall in this direction
Fall, but would not drop after being assemblied in slide rail, do not influence slide rail integrally to use function, but be not easy to part turnover and pacify
Dress.
Fig. 7,8 also show two kind application examples of the utility model slide rail in display lifting support frame, wherein propping up
Frame uses in the longitudinal extrusion molding in metal edge, support while formation longitudinal direction inner chamber and its partial lumen is adapted to the outer rail of this slide rail,
Rack bore side is outwards provided with elongated slot and goes connection lifting module outside support so that the connecting portion of interior rail stretches out and lift, at least one
Gas spring (not illustrated in figure) provides the power source of up and down balance system display gravity, and gas spring is locally disposed longitudinally on along rack bore
In it, gas spring upper end supports the lower end of interior rail, and lower end contradicts support bottom, and (such as support bottom is connected with base and can also contradicted
On base, because the gravity of display is away from support, therefore preferably contradicts nearest from display position in connecting portion lower end and (note
Inner chamber even outer rail will do some structures and avoid gas spring), such stress is relatively good, and pedestal upper end has top cover, and lower end is usual
Connect base.So display can be easily with stopping arbitrary height.Obviously, it also can use the multiple power of determining bullets of multiple rows of distribution up and down
Spring replaces rail in gas spring, the connection of fixed force spring one end, and other end connecting bracket forms up and down balance system elastic force, fixed force spring
Position may be provided at the side of outer rail in die cavity or be arranged on the bottom of outer rail in die cavity leading by two up and down and the above again
Take turns the equilibrant force that the rail in cable traction realizes display adjustment.
The utility model slide rail, overcome existing slide rail be limited to its ball only have two row and for contraposition arrangement type construction
Slide rail thickness caused by factor still very thick defect, and the defect that can not be used alone, by using the dislocation of four row balls
Arrangement carries out substantially important improvement to it, slide rail thickness is further reduced, and makes the interior rail more stable, rigidity of slide rail
Higher, an independent slide rail can be used for support frame, provide a kind of thickness thinner liter for more thin display lifting support frame
Drop ball slide rail, can apply to being more thinned in the display bracket of requirement, expand its application neck
