It refers to shown in Fig. 2 to Fig. 8, and emphatically referring to Fig. 7,2, a kind of ball-type lifting support provided in this embodiment
Frame comprising:
The pedestal 9 of one plate body shape is set on working face;
One bracket 7, substantially in elongated plate body shape (because wanting slim, so generally plate body shape;Illustrate but it is unlimited with
This, material and forming are such as shaped using aluminium alloy compression casting, and lower part is equipped with a big threading hole 75 and walks for cables such as displays
Line), and be generally vertically arranged on the pedestal 9, its plate face towards display side of the bracket, which is equipped with, to be recessed
An accommodation groove 71, the bottom surface of the accommodation groove 71 offers two vertical, long vertical slots 74;(on accommodation groove 71 described in this example
Two vertical slots 74 are crossed therebetween for aftermentioned two interconnecting pieces 22);
One sliding rail 10, is set in the accommodation groove 71 that (this sliding rail is constituted from overall, convenient to understand, also can be considered
Two common skid rails divided right and left are composed), wherein including again:
Two outer rails, in terms of cross section, each outer rail 1 is substantially ushaped, and the plate body of simultaneously general parallel orientation is set including two neighbours
Shape raceway plate 11 (between two raceway plates 11 general parallel orientation, while forming an accommodation space between it because alternate), two rollings
The ipsilateral longitudinal edge of guidance tape 11 1 mutually it is curved prolong the integrally formed disjunctor portion of interconnection 12 (for example but not limited to this:I.e. from
Cross section sees that outer rail 1 is overall in approximate U-shaped, and disjunctor portion 12 therein is equivalent to the back cover section of U-shaped, the two raceways plate
11 are equivalent to U-shaped and remove two sections that back cover section is left behind;The outer rail 1 can be by steel plate integrated punching or rolling forming;One
As several threaded holes are set on the face along longitudinal direction of disjunctor portion 12 or open-work be used for in display lifting support frame column or
Bracket 7 is connected;Its longitudinal both ends of outer rail 1 can add block, to stop mobile internal rail 2 to be deviate from);Two outer rails 1 its respectively
U-shaped opening vis-a-vis, compartment of terrain is fixed in bracket 7;
Two internal rails, each internal rail 2 (be such as but not limited to this, can by steel plate punched or ferrous based powder metallurgical one at
Shape), (groove portion 21 between the two raceway plates 11 of its affiliated sliding rail substantially is set in the groove portion 21 of plate body shape including one
Can be that it is mostly between it), and extended by groove portion one from the outer rail U-shaped outward opening is curved
(interconnecting piece 22 is attached one interconnecting piece 22 for such as going up and down module 6 with the part on display lifting support frame, settable number
A threaded hole or open-work, specifically how curved extend is considered as and goes up and down being adapted to connection structure for module 6), the internal rail 2
Keep gap (touching because there is relative motion that cannot mutually wipe between the two, so there should be gap) everywhere with the outer rail 1;
Four column balls and corresponding elongated pearl frame 4, each column ball are arranged along sliding rail longitudinal direction, and each column ball wraps
It includes a plurality of balls 3 (for example ball 3 is using steel ball), each ball 3 in each column ball is spaced, is accommodated and is held in correspondence
The pearl frame 4 (be such as but not limited to, 4 structure of pearl frame is the receiving hole that band one arranges 3 quantity of ball in corresponding ball column
Strip stalloy) on corresponding number receiving hole in;From sliding rail cross section, the centre of sphere of the adjacent four column ball
Line of centres interconnection substantially constitutes an isosceles trapezoid, and (centre of sphere for adhering to 4 balls of four column balls separately is linked up with straight line to be seen, note
Meaning, which should remove, forms cross one another line of centres between 4 centre ofs sphere), the corresponding same side of two 21 plate bodys of groove portion with
It is respectively common respectively between two neighbouring 11 plate faces of raceway plate to contradict the 3 (shape of ball in bottom two-end-point in isosceles trapezoid
Two ball channels of the two column ball are contradicted at common clamping), the another side of two 21 plate bodys of groove portion respectively with
Two balls in isosceles trapezoid bottom two-end-point are contradicted between 11 plate face of raceway plate of neighbouring another two jointly (to form altogether
Another two ball channels of the column ball are contradicted with clamping);The height of the isosceles trapezoid≤(being averaged for the four column ball 3 is straight
Diameter (that is, the average computation if four column ball diameters are not equal)+3) (㎜) (in terms of sliding rail cross section, it is clear that in certain condition
Under, the height of isosceles trapezoid is smaller, it is meant that and the ball 3 of bottom two-end-point the mobile to another two ball direction in isosceles trapezoid,
Sliding rail thickness is smaller, also implies that the local plate body of groove portion 21 is curved more very;In this way, with using the two of two column contraposition arrangements
Prior art construction sliding rail compares under the same conditions, sliding rail thickness can be obviously reduced using ball dislocation arrangement, through practical table
It is bright, the variation of dislocation arrangement size is carried out in this formula size section, the size for reducing sliding rail thickness direction can be more advantageous to, added
Work technique is best;Sliding rail can be made most thin in thickness direction minimum, sliding rail as far as possible;Another obvious, which is equivalent to existing skill
Two sliding rails of art;It is two interconnecting pieces between three in application, being mutually connected between two interconnecting pieces and lifting module three
22 elder generations connect again with sliding part 61 after being mutually fixed with one or two interconnecting pieces 22 are individually connected with sliding part 61, it is clear that
Effect be it is of equal value, can select as needed, two outer rails are respectively fixedly connected with bracket, and such two outer rail could also be positioned);It is described
Pearl frame 4 is equipped with stopper section 5, touches, drives with and avoid voluntarily sliding that (sliding rail is to be raised the internal rail 2 of movement
For lifting, outer rail 1 is fixed in generally vertically arranged bracket when application, the then reciprocal lifting of internal rail 2, the pearl frame 4
Also and then reciprocal lifting, it is apparent that after pearl frame more than 4 times liftings, because of 4 self gravity reason of pearl frame and because inevitably having in the rolling of ball 3
The reasons such as asynchronous and fall pearl frame 4 gradually downward, namely the repeatedly relatively described internal rail 2 of the pearl frame 4 after relative movement
Degree of overlapping can gradually decrease, at this moment participate in roll work 3 total quantity of ball will accordingly reduce, thus reduce internal rail 2 with
3 quantity of ball that outer rail 1 is supported simultaneously, the work for influencing sliding rail such as move rigidity, and display may shake, is unstable;Therefore,
It is so-called to set backstop, refer to and do a stop configurations on the pearl frame 4, such as local stamped bumps, riveting, welding smallclothes, makes this only
Gear structure rises in internal rail 2 can be touched gear on mobile nearly highest point position by internal rail 2 and to be forced to drive band upward together, certainly should
Stop configurations do not open again it is too big, can the smooth downlink in outer rail 1, i.e., it is when rising to nearly highest point every time by internal rail 2
It touches the stop configurations of pearl frame 4 and forces that pearl frame 4 is driven to return original position again, be unlikely to gradually to fall down, the backstop
Structure, that is, so-called stopper section);The groove portion plate face and the raceway plate plate face are in the corresponding position contradicted with each ball
Upper difference is equipped with ball raceway along longitudinal direction, and (raceway is usually to occur in the form of shallow slot, for example this example is straight with ball 3
The raceway of the comparable local arc-shaped slot of diameter, guiding of the raceway for ball 3 to roll keep the internal rail 2 outer rail 1 relatively described
Stabilization is set, separation will not be laterally sliped off, meanwhile, the groove face of ball 3 and the raceway can also be carried with dispersion force with face contact
Effect, avoids or mitigates stress concentrating on face a bit, raising contact stiffness and service life, what this will be appreciated that;Certainly
Saving on internal rail 2 and outer rail 1 wherein special a certain may still make the relatively described outer rail 1 of the internal rail 2 to raceway at two
Position is determined, but at this moment internal rail 2 and rigidity, the intensity of 1 relative motion of outer rail can decline after all, one to the two place stress
Excessively concentrate on material surface a bit, it is bad, it is not recommended that use, also therefore, be Unify legislation, it is believed that one to two place rolling
The raceway in road still have only depth be approximately zero);
It is mobile (it is quite obvious natural result) that internal rail 2 through the ball carries out reciprocating linear relative to the outer rail 1;
Two outer rails 1 are fixedly arranged on respectively on the wall surface to form the accommodation groove 71;
One lifting module 6, including a sliding part 61 (for grillage like members, for example stamping parts is composed 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);Corresponding two internal rail 2 is respectively fixedly connected in 61 two sides of sliding part (being generally in two sides)
The interconnecting piece 22 (such as the interconnecting piece 22 pass through after the vertical slot 74 is stretched out outside the bracket 7 with the sliding part
61 are connected, and the sliding part 61 puts in bracket 7 with its effect that is connected and is also in turn, visual specific structure which kind of more
Conveniently, it more meets the requirements and selects);
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 setting (such as this example point four rows up and down, every row one, it is clear that every row can also more than one) in the bracket 7 (such as
This example is in the accommodation groove 71 of bracket 7), at least one fixed force spring itself is two at least two fixed force spring
The elastic steel sheet similar to three layers fits closely compound winding together into (closely being pasted by two to three layers of similar elastic steel sheet
Conjunction overlapping is compound to be equivalent to a steel disc, winds together together, and every circle is close to from each other, so that it is in general shape
Increase unobvious but spring tension accordingly to increase at multiple, althoughs note that the fixed force spring of this internal structure quantitatively still regards
For a fixed force spring);Each fixed force spring 8 includes a winder 81 (one hollow cylinder of shape approximation) and a connecting pin
82, and the winding axis of the winder 81 substantially generally perpendicular to the plate face of the bracket 7 (winding axis select in this way after,
Size of the fixed force spring on the direction of backing thickness can greatly reduce, and certain fixed force spring 8 is in the backing thickness direction
Size, which reduces the elastic force for single spring, to be declined, but can total spring force be made to meet by multiple rows of accelerate up and down again
It is required that final such arrangement greatly reduces ruler of the fixed force spring on backing thickness direction than the prior art
It is very little, while still meeting total force value requirement, to realize the ultra-thin of bracket 7), the winder 81 and connecting pin 82 are set respectively
Even the bracket 7 and the sliding part 61 (internal rail 2 and the sliding part 61 be it is connected, the connecting pin 82 is connected to described
Sliding part 61 protrudes into the part in the bracket 7;Surface can be rotated relative to bracket 7 when as winder 81 due to its work, therefore
The company of setting of itself and bracket can select according to specific structure, for example this example uses the hole among winder 81 being sleeved on bracket 7
In fixing axle 72, the casing between certain fixing axle 72 and winder 81 equipped with plastic wear comes dottle pin, 81 two sides of winder
Face is also typically provided liner that plastic sheet etc. separates etc. and carries out anti-attrition and prevent from scratching bracket 7);When the sliding part 61 together with
When the internal rail 2 moves downwards, each fixed force spring 8 by phase strain stretch and keeps elastic pulling force (fixed force spring quilt
Its pulling force still keeps approximately constant when stretching, and the power of each fixed force spring is added to the gravity that can substantially balance display,
It realizes display with stopping in any height and position, a friction pair can be set in lifting travel also certainly in practical structures to produce
Raw additional frictional resistance, the position for stopping display is more steady, feeling is better for descending operation).
Above please simultaneously emphatically referring to Fig. 7 and Fig. 2.
Further, the sliding part 61 further includes (such as the steel plate of transfer strip 23 for the strip that one substantially vertically disposes
Punching press or casting forming or powder metallurgy formation), the interconnecting piece 22 of the internal rail 2 is (big outward by the plate body of the groove portion 21
Body is seen) one it is curved prolong to be formed (be such as but not limited to this:Its curved shape prolonged of one etc. can be according to the corresponding connection of connector
Structure is adapted to);The interconnecting piece 22 be equipped with connection screw hole or open-work (specifically should be correspondingly connected with part physical fit
Selection);The interconnecting piece 22 (such as the lower part for usually selecting the longitudinal direction of interconnecting piece 22) and described fixed is respectively fixedly connected in the transfer strip 23
Power spring 8 the connecting pin 82 (because there is multiple rows of fixed force spring 8 up and down, longitudinally connected span is obviously longer therewith for sliding part 61,
The two sides of sliding part 61 can integrally extend forming transfer strip 23, such as die cast metal or powder metallurgy formation, it is clear that be processed into
Shape and installation difficulty all can be larger, thus can also separate machined be fixed with one again;Such as this example, the individually processing of transfer strip 23,
For example die cast metal or powder metallurgy formation, upper section connect with 61 two sides of sliding part and the interconnecting piece 22 solid respectively
Even, side especially middle and lower sections are then connected with the connecting pin 82 of multiple fixed force springs arranged up and down;Because there are two switchings
Item 23, therefore each transfer strip 23 should share the fixed force spring for connecting a part of quantity at least two fixed force springs, so as to
Stress equalization).
