Triangle pearl arranges slim ball slide rail

Technical field

It the utility model is related to one kind and (refer to liquid crystal type, including display, monitor, plate display for display Device, similarly hereinafter and display for short) lifting in lifting support frame ball slide rail, more particularly to the rolling of slide rail thickness slimming Pearl slide rail.

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 is 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.For display bracket in addition to providing the function of support display, majority must possess adjustment display The function of height and position, this lifting module for requiring to connect display in display bracket can lift.

Act smooth because ball sliding rail has, stabilized structure, durable, movement parts gap is small, rocks the advantages that small, because This be widely used be used as in display lifting support frame lift module lifting when support (usual slide rail uses in a pair, On both sides in the support of placement, because the support in display bracket is generally vertical, therefore the slide rail in installation settings support Also it is and then generally vertical, notice that support majority is provided on base, therefore, what support had can be with respect to base around substantially vertical Line rotates, and some then can be around the horizontal axis slightly pitching rotation one of base top (having a protuberance stretched out upwards on base) Determine low-angle, but substantially or vertical direction).But people's aesthetical interest is varied widely at present, increasingly require aobvious Show the more slimming of device lifting support frame, and the bottleneck being thinned is being thinned for the thickness of slide rail, but slide rail developing history It is very long, thinned several wheels, and rail structure part is few, then enter one be thinned will be extremely difficult, in display in currently available technology Its most thin slim slide rail of the ball slide rail used in lifting support frame is double row ball contraposition arrangement and interior rail is plate body type, It is 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 direction of the two raceways plate 11a Integrally extension bending interconnection is formed and is connected with the support 7a in display lifting support frame at edge；

Rail 2a in one, there is a groove portion 21a and a connecting portion 22a, groove portion 21a to be straight, flat board plate body shape and set 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, accommodate be held in corresponding in two row receiving holes corresponding to 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 ball be referred to as in the industry row " contraposition " arrange (we are at this accordingly On cross section also an angle can be tilted with the slide rail thickness direction to the normal 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, make 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 be 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, interior rail 2a is in a less firm position location, therefore, be also not suitable for rocking the feelings for requiring very tight to display Use under condition, can not more be lifted in support frame using a single one slide rail.Moreover, its outer rail of prior art, interior rail, Pearl frame and ball road etc. are all linear construction, therefore are limited to this structural factor, and its slide rail can only provide straight line Guide path, also hence in so that being only able to using the lifting module of the display bracket of this kind of ball slide rail along straight line path Shift reciprocately rolls, and limits the design of Display support frame mechanism and use range, and particularly its outward appearance and moulding is dull, no Attractive in appearance, appearance and modeling does not have feature, and visual angle can not preferably meet ergonomics when lifting uses.

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, can not be applied to more slim In display bracket product structure.Therefore the improvement of slide rail thickness reduction how is carried out by existing structure, and on this basis Round and smooth shape movement can also be realized, existing ball slide rail is employed for thinner requirement and with outward appearance more preferably arc In the display bracket of moulding, it has also become one of industry important topic to be solved.

Embodiment one

Refer to shown in Fig. 2 to Fig. 9, a kind of triangle pearl arranges slim ball arc-shaped slide rail, is specially used as lifting branch for display Ball slide rail (meaning that its application field is specific) in support, comprising：

One outer rail 1, including two general parallel orientations, alternate 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 fonts 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 mould with the part on display lifting support frame Block 6 etc. is attached), the groove portion 21 be arranged between the two raceway plates 11 (groove portion 21 can be its it is most of at 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)；

Three rows of balls and corresponding elongated pearl frame 4, each row ball arrange along slide rail longitudinal direction, each column ball Include a plurality of balls 3 (ball 3 such as uses steel ball), each ball 3 in each column ball is spaced, accommodates guarantor The pearl frame 4 (is such as but not limited to, the structure of pearl frame 4 is the quantity of ball 3 in the corresponding ball row of the row of band one corresponding to being held in Receiving hole strip stalloy) on respective amount receiving hole in；From slide rail cross section, the ball of the three rows of balls The heart substantially in isosceles triangle (adhere to separately three rows of balls 3 ball centre ofs sphere linked up with straight line see) arrangement, the groove portion 21 It is common between the one side of plate body and neighbouring one plate face of raceway plate 11 to contradict the ball 3 in isosceles triangle corner point (forming the ball channel that common clamping contradicts the row ball), the another side of the plate body of groove portion 21 with it is neighbouring another Common two balls contradicted in the base angle point of isosceles triangle two (form common clamping to contradict between one plate face of raceway plate 11 Another two ball channels of the row ball)；

The height of the isosceles triangle≤{ average diameter of three balls 3 is (average if three rows of balls diameter does not wait Calculate)+3 mm (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 top The ball 3 of angle point more moves to another two balls direction, and slide rail thickness is smaller, also implies that the middle part local sheet of groove portion 21 Body is more bent along slide rail thickness direction to isosceles triangle base side direction to be protruded；So, with being arranged using two row contrapositions The prior art construction slide rail of cloth is contrasted under the same conditions, and slide rail thickness can be substantially reduced using three rows of balls dislocation arrangement, Through actually showing, the change of dislocation arrangement size is carried out in this formula size section, can be more beneficial for reducing slide rail thickness direction Size, processing technology is optimal；Slide rail can be made thickness direction is minimum as far as possible, slide rail is most thin) (pay attention to, such as prior art The contraposition arrangement of two row balls 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 is stable, and uses three rows of balls dislocation arrangement that interior rail position obviously can be made to be supported and stabilized, and slide rail One also can be used alone in support frame, what this will be appreciated that)；

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 certainly Row slide (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 also with Reciprocal lifting, it is apparent that after more than 4 lifting of pearl frame, has difference unavoidably in being rolled because of the self gravitation reason of pearl frame 4 and because of ball 3 Step etc. reason and pearl frame 4 is dropped gradually downward, namely repeatedly relative movement after the relatively described interior rail 2 of the pearl frame 4 it is overlapping 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 and outer rail 1 Rigidity is such as moved in the quantity of ball 3 supported simultaneously, the work for influenceing slide rail, and display is possible to rock, is unstable；Therefore, it is so-called If backstop, refer to do a stop configurations on the pearl frame 4, such as local stamped bumps, riveting, welding smallclothes, make the backstop knot 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 be by Interior rail 2 touch the stop configurations of pearl frame 4 when rising to nearly peak every time and force to drive pearl frame 4 return again original position, It is 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 outer rail 1, the interior rail 2, the pearl frame 4 are the circular arc warp architecture around same axis and fitted each other With so that the interior rail 2 and the relative outer rail 1 of the energy of the pearl frame 4 do circular movement；The interior rail 2 and the pearl frame are with respect to institute The movement locus for stating outer rail 1 is the circular arc around the axis, and the axis is remote and parallel to the two base angle point balls Arrange common face and generally perpendicular to the line at slide rail longitudinal direction both ends；

The interior rail 2 through the three rows of balls rolling and guiding can relatively described outer rail 1 carry out reciprocal circular arc moving Dynamic or rectilinear movement (it is quite obvious natural result).

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 also opens up Corresponding rivet hole, then it is connected with rivet 52, can also uses welding such as spot welding to substitute rivet 52 certainly and be connected), when described interior Rail 2 can touch the transverse slat 51 when rising and drive the pearl frame 4 and then upward, avoid because pearl frame 4 back and forth lifting repeatedly and from Row gradually falls, while does not influence the 4 reciprocal elevating movement of pearl frame 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, after paying attention to 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 The convex structure of integrated injection molding one forms stopper section 5 in the lump on top thereon；Obviously, similar bulge-structure can have a variety of variants； Paying attention to the raised shape, and can touches on interior rail 2 top to block simultaneously to guarantee in the raceway of outer rail 1 lifting carriage 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, avoid voluntarily gradually falling because pearl frame 4 back and forth lifts repeatedly, while do not influence the 4 reciprocal elevating movement of pearl frame again. (this stopper section is simple in construction, easy realization, but three pearl framves go up and down with different paces and determine synchronization).

Further, the disjunctor portion 12 of the outer rail 1 integrally extends curved for the homonymy longitudinal edge of the two raceways plate 11 Song interconnection one is into (for example but not limited to this：Make what its shape of outer rail 1 was totally integrated in approximation in terms of cross section U-shaped, this relatively simple for structure, good rigidity, stably are easy to be used alone, had enough to meet the need；As shown in Figure 2)；From slide rail cross section See, the length for contradicting the raceway plate of isosceles triangle corner point ball is less than the length of another raceway plate (such as Fig. 2 institutes Show, what this will be appreciated that, have less because contradicting ball and showing, it is clear that the raceway plate for only contradicting a row ball can be relatively short A bit, to save material consumption；The outer rail 1 of illustrating is steel stamping part shaping or rolling forming).

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 the small forming difficulty of thickness；Two L shaped plate parts can be steel plate stamping Casting die or rolling forming part), the long sides of two L-shaped corresponds to the two raceway plates 11 respectively, the short sides of two L-shaped then it is overlapped simultaneously Being connected, (rivet can not be shown mutually with small rivet rivet clasp in figure by being connected, certainly also solderable；The connected short side is equivalent to disjunctor Portion 12), the two short sides overlapping of the two L-shaped parts is longitudinally arranged on the branch in connection display lifting support frame along slide rail The screwed hole or through hole (riveting location of two L part short side overlappings it should be noted that its position should stagger) of frame 7；Wherein two L shaped plates (when this can be such that the outer rail 1 is installed in the support 7 of display lifting support frame, thin L-shaped part can be borrowed the steel plate thickness of part to be different With or make use of the intensity of of support 7 itself to do rear portion backrest to support, and be fixed on the side of support 7 but the long side of L-shaped is in If the thick rigidity that can so still ensure that cantilever of the L parts of cantilever, the global stiffness and intensity for making outer rail 1 do not decline, Ye Jitong The thickness of two raceway plates of distribution is crossed, the rigidity and intensity of slide rail can not be reduced while meeting that slide rail thickness is thinned, divides two pieces Manufacture is to reduce the difficulty on process for machining and manufacturing, certainly, sometimes due to the corresponding structure of support 7 limitation, which L shape part Also need according to circumstances to do opposite selection to be thicker, and can not only consider rigidity and intensity).It also has a kind of variant, please simultaneously Shown in Figure 9 emphatically, the outer rail is divided into two parts and combined, and one is substantially in I fonts, and another is substantially in zigzag (its anufacturability is relatively good, and processing is simple, and precision is easily controlled).

Further, it is please simultaneously shown in Figure 6 emphatically, the vertical side of the edge phase of the pearl frame 4 of the three rows of balls Mutually it is connected as a single entity, makes (this in 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 That a kind of three pearls frame 4 links into an integrated entity the structure of formula, pearl frame semi-finals degree and rigidity can be a shade better, meanwhile, the lifting of three pearl framves 4 it is same Step property is also quite a lot of；But from cross section, because three pearl framves 4 are linked to be a U-shaped, it certainly will tie up between the periphery of interior rail 2 and outer rail 1 The certain interval width in gap, correspondingly it 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 the disjunctor portion 12 of the outer rail 1 is then formed by the side channel local wall thickness of support 7 (because the part-structure of support 7 can play a part of disjunctor portion, so can be by partial display support frame medium-height trestle 7 itself Shape and strength and stiffness, at this moment need to only process two raceway plates 11 and be fixed on the side channel inwall of support 7, can reduce Material consumption, simplifies outer rail 1 structure, and the support 7 in figure can use aluminium alloy or kirsite extrusion molding)；The two raceways plate 11 be Steel Sheet.

Further, the pearl frame 4 is integrally formed or plastic injection piece is integrally formed by sheet metal punching press.

Further, the connecting portion 22 of the interior rail 2 by the plate body of the groove portion 21, outwards curved prolong by (substantially seeing) one Formation (is such as but not limited to this：Its curved shape prolonged of one should be according to the corresponding connection of the lifting module 6 of outside to be connected Structure is adapted to)；The connecting portion 22 is provided with the screw of connection or open-work (specifically should be corresponding with the lifting wait of module 6 The physical fit of the part of connection and selection)；The interior rail 2 is steel stamping part or the iron-base sintered metal piece (connection in Fig. 7,8 Portion 22 is exactly powder metallurgy structure, and the shape matching so connected is easily adapted to lifting module 6)；It is the interior rail 2, described outer The curvature of the circular arc of rail 1 and the pearl frame 4 bending selects to determine and be mutually adapted between 0.6-1.8 scopes, to show Optimal viewing angle is obtained during device eustasy and makes supporting support that there is optimal circular arc bending outward appearance.

It is noted that it is 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 in the lump, but not limited to this：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 rotates freely, and will not make the generation of colliding each other of a plurality of balls 3 dry again Relate to, rolled so as to ensure that each column ball can guide conduit along the ball of rail in slide rail 2 and outer rail 1.Therefore, illustrating but unlimited 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 its shape is not necessarily non-to be complete round, as long as major part is circle), the side of each receiving hole Towards the ball surface of ball 3 accommodated, integrally bending extends a pair of dots to edge on the plate face both sides of pearl frame 4, that is, is formed Two clasp component (not shown) of clasp ball 3, two clasp components, which pay attention to separating, here is located at the substantially straight of receiving hole It is relatively good on the two-end-point in footpath, and the diameter where the end points of two sides is preferably mutually vertical, preferably clasp to live to roll The sphere of pearl 3 makes that its is more stable, it is more smooth to rotate and is not easy to drop)；The work that the actual clasp component can maintain ball 3 is former Reason is, using the elasticity of the material itself of pearl frame 4, i.e., using micro-elastic caused by small clasp component partial by ball 3 Slightly firmly can just be installed into receiving hole, at the same because after dress retainer elastic recovery and can flexibly keep out the ball surface of ball 3 and make It is 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 The thickness of pearl frame 4 is actual preferably thicker than stamping parts, and the orifice edge diameter of the receiving hole two sides is all slightly smaller than The sphere diameter of the ball 3, the cavity for coating the ball 3 slightly is formed, shaped equivalent to inside hole by the sphere of the ball 3, this Sample can realize that the ball 3 easily is loaded into the receiving hole ball 3 and will not then drop again, also can because of the micro-elastic of material Realize the purpose of clasp component.Certainly, in above-mentioned, the plate face of the pearl frame 4 only sets phase in the diametric(al) of one side receiving hole Interval, at least two clasp components it is also possible, but now, the diameter in the hole is slightly smaller than steel ball size, it is clear that At this moment steel ball can only be limited in a direction in receiving hole, and other direction is then free, though ball 3 can be in this direction Drop, but would not be dropped after being assemblied in slide rail, do not influence slide rail and integrally use function, but be not easy to part turnover and peace Dress.

Fig. 8 shows application of the utility model slide rail in display lifting support frame.

The utility model slide rail, overcome existing slide rail be limited to its ball only have two row and for contraposition arrangement type construction The defects of slide rail thickness caused by factor is still very thick, and the defects of can not be used alone, by using the dislocation of three rows of balls Arrangement carries out substantially important improvement to it, slide rail thickness is further reduced, and the interior rail of slide rail is more stablized, rigidity 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, it can apply to being more thinned in the display bracket of requirement, it is moreover, simultaneously sliding Rail additionally uses arc-shaped structure, and circular arc movement can be done by realizing interior rail, and outward appearance is more attractive, and moulding has more feature, visual angle More advantageously meet ergonomics, expand its application field, widened the application of slide rail product, made Display support Frame outward appearance is thinner, more attractive in appearance, preferably meets the new fashion and esthetic requirement of people.

It the foregoing is only preferable possible embodiments of the present utility model, non-therefore limitation protection model of the present utility model Enclose, therefore the equivalence techniques change done such as with the utility model specification and schema content, it is both contained in the utility model Protection domain in.
