Description
Technical field
The present invention relates to the side sway type arc-shaped slide rail of a kind of different cambered surface position, belong to the bracing frame technical field that display is supporting, particularly relate to the arc-shaped slide rail structure technology having in elevating function bracing frame.
Background technology
It is known that, the utilization of liquid crystal or LED or plasma display panel (the most all claiming display or display screen) is the most extensive, and the use overwhelming majority of display need to be equipped with corresponding bracing frame, to support display, and bracing frame generally requires the oscilaltion display needs with applicable different personnel.nullFor meeting these requirements，Support frame structure is generally on the base of tabular vertically equipped with a column，A cavity volume is typically had inside described column，Cavity volume each side arranges that fixing a slide rail (notes，Interior rail in slide rail or the motion both outer rail are clearly relative，Therefore when being connected, select described interior rail or described outer rail with described column,Can according to circumstances choose，General described column connects the described outer rail in fixed rack，The most described outer rail is motionless，And described interior rail can slide up and down,Describe by this kind of selection below the present invention)，The interior rail of two slide rails connects a movable ear page of slip lifting chain，Another movable ear page of described slip lifting chain then connects (be directly connected to or the hinge that display can be made to spin by another again and be indirectly connected with) display，Display can be around the hinge axis pitching of described slip lifting chain to adjust visual angle；Owing to fixed force spring can balance the weight component of display, when making lifting can feel the most laborsaving and make location of displays stable, therefore described fixed force spring two ends connect described slip lifting chain (or being directly connected to make the interior rail of oscilaltion) and described column respectively, this is had to form the most complete display bracket, and the lifting intermediation of slide rail seems critically important among these, it can greatly reduce and stably make the frictional resistance of the OQ t each part of motion, the resistance making display lift is little and uniformly makes operating handle good, therefore slide rail is the most supporting along with a large amount of use of bracing frame.
Rail structure is divided by its movement locus at present two big classes, slide rail the most for linear motion and the most relatively new arc-shaped slide rail moved along circular arc line.nullIt is a kind of side sway type arc-shaped slide rail with the immediate prior art of the present invention that arc-shaped slide rail apoplexy due to endogenous wind has a kind of，Seeing number of patent application is: 201420860090.7(side sway type arc-shaped slide rail)，(certain immediate prior art also includes the slide rail similar with this patent application)，See Fig. 5、Fig. 6、Fig. 7 (notices that in Fig. 7, the lines of vertical direction are to have slight curves)，Its concrete structure (seeing the most emphatically Fig. 1) including: the outer rail 2a of U-shaped like (transverse section (note: the present invention is called for short vertical cross section or transverse section) being perpendicular to slide rail length direction)、Ball 4a、The interior rail 1a of transverse section U-shaped like、Transverse section U-shaped like as described in the middle rail 3a(of ball 4a retainer be equivalent to the ball retainer of the common ball bearing launched),Cooperate between them，Side walls on described outer rail 2a forms cambered surface 5a being coated with described ball 4a part surface the most respectively with the side walls on corresponding described interior rail 1a，The arc-shaped slot rolled for described ball 4a is jointly surrounded to cooperate，Described ball 4a all it is arranged at intervals with to play the effect of described ball 4a retainer in described middle rail 3a side walls，The described side walls of described middle rail 3a is arranged in correspondence with between described outer rail 2a side walls and described interior rail 1a side walls，Described outer rail 2a carries out relative roll type by the described ball 4a that interval on described middle rail 3a is installed with described interior rail 1a and moves；Described outer rail 2a, described middle rail 3a, described interior rail 1a are the structure around the bending of same axis circular arc, described axis is in described outer rail 2a, described middle rail 3a, the same side of described interior rail 1a the degree direction being parallel to slide rail, and the relative movement orbit of described middle rail 3a, described outer rail 2a and/or described interior rail 1a is the circular arc camber line around this same described axis；That is, be equivalent to that the rail described inside and outside, middle of generic linear slide rail is all carried out circular arc bending forming by this same described axis to become this kind of side sway type arc-shaped slide rail.
Two slide rail orientation of its actual column 8a inner chamber being arranged in bracing frame are arranged as shown in Figure 2, for assembling facility, installing hole it is equipped with for the described column 8a being connected in slip lifting chain or bracing frame with (generally on described interior rail 1a and described outer rail 2a, described outer rail 2a is connected with described column 8a, and described interior rail 1a is connected with described slip lifting chain；Meanwhile, for the described interior rail 1a extreme position when making circular motion can limited, backstop, described outer rail 2a two top bending become wall or use other similar structures with the extreme position of the spacing described interior rail 1a of backstop, as shown in Figure 5,6)；Obviously, the face of the fixing described outer rail 2a of described column 8a correspondence installation also should be suitable with the arc-shaped structure of described outer rail 2a；In described in two, rail 1a is connected to described slip lifting chain (described slip lifting chain is also connected to display), so, when display oscilaltion, its track is also the circular arc around this same rotation axis, thus realize the lifting of display circular arc, but shape in the most important thing is therefore to make adaptive described column 8a not only especially, especially profile also can follow respective curved (also including being coated with the outward appearance plastic cladding element of described column 8a), therefore complete machine appearance and modeling is more more aesthetically pleasing than the right cylinder of dress line slide rail.
Though the prior art has above-mentioned bigger advantage, but because it described, the layout of cambered surface 5a creates some problems also, first (Fig. 1 is seen in the transverse section being perpendicular on slide rail length direction, though althouging note that in figure, there is described ball 4a slide rail width both sides, but described ball 4a may will not simultaneously appear on this same transverse section because the position that arranges in described middle rail 3a side walls is the most variant, but there is no any impact in the problem scope that we are discussed, for analyzing conventionally, the described ball 4a of these cross-sectional view both sides is all painted on this same transverse section, lower same), described ball 4a ball surface diameter corresponding vertex on slide rail thickness direction is for some a and puts b, described ball 4a ball surface diameter corresponding vertex on slide rail degree direction is for some c and puts d；nullDue to arc-shaped slot as described in aforementioned be by as described in interior rail 1a and as described in outer rail 2a respective as described in cambered surface 5a surround，Therefore，When two side sway type slide rails arrange installation as shown in Figure 2 in the described column 8a inner chamber both sides of bracing frame，If now display partical gravity and personnel pull display force action up and down，Rail 1a or described outer rail 2a interior described in slide rail will certainly be produced the component along described slide rail thickness direction，And in the direction，The described a point on the most described ball 4a ball surface on slide rail thickness direction and described b point，Because of not by any area in described cambered surface 5a even a small amount of cladding、Reveal all the details、" barb "，And be at the neutral gear without cladding of cambered surface 5a described in two，Obviously，Under above-mentioned power effect，Described ball 4a tries hard to move (edge line that contact point the most each other has been moved to described cambered surface 5a) to the edge of cambered surface 5a described in two by being pushed all the time by described interior rail 1a or described outer rail 2a，And it is the lowest further away from the machining accuracy of its cambered surface of described cambered surface 5a middle part、The contact point place female surface that described ball 4a rolls is the least，The most unfavorable，Let alone and moved on to the edge line of described cambered surface 5a and contact，Notice that described ball 4a the most also wants oscilaltion to roll，Obviously these upper and lower whole lines of described cambered surface 5a edge line are more difficult to ensure that processing is smooth，Roll inclement condition；Therefore necessarily cause lifting roll time the most smooth, resistance is uneven, cause display lifting feel bad.
Summary of the invention
The deficiency existed for prior art, the present invention seeks at the side sway type arc-shaped slide rail providing a kind of described cambered surface location improvement, and it can be more smooth and easy when lifting stress, and drag uniform, feel is good.
To achieve these goals, the present invention realizes by the following technical solutions:
A kind of side sway type arc-shaped slide rail of different cambered surface position, including the outer rail arranged that cooperates, ball, interior rail, middle rail, side walls on described outer rail forms the cambered surface being coated with described ball part surface the most respectively with the side walls on corresponding described interior rail, the arc-shaped slot rolled for described ball is jointly surrounded to cooperate, described ball all it is arranged at intervals with to play the effect of described ball retainer in described middle rail side walls, the described side walls of described middle rail is arranged in correspondence with between described outer rail side walls and described interior rail side walls, outer rail carries out relative roll type with described interior rail move by being spaced the described ball of installation on described middle rail；Described outer rail, described middle rail, described interior rail are the structure around the bending of same axis circular arc, described axis is the circular arc camber line around this same described axis at described outer rail, described middle rail, the same side of described interior rail the degree direction being parallel to slide rail, the relative movement orbit of described middle rail, described outer rail and/or described interior rail；In the transverse section being perpendicular on slide rail length direction, described ball ball surface diameter corresponding vertex on slide rail thickness direction is some a and some b, and described ball ball surface diameter corresponding vertex on slide rail width is some c and some d；It is characterized in that: the described cambered surface of described interior rail extends always and crosses a point on described ball surface and c point and it is formed cladding, the described cambered surface of described outer rail extends always and crosses the b point on described ball surface and its formation is coated with by d point；Thus, be coated with described a point and described b point with ensure described ball contact point can fall all the time in described cambered surface roll, be coated with described c point and described d point with guarantee described interior rail will not deviate from from described outer rail.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with detailed description of the invention, the explanation present invention is expanded on further.
nullSee Fig. 3，Obviously，The location arrangements that the present invention and prior art are mainly described cambered surface is different，Other should say the most close (so partial content the most too much describes)，The outer rail 2 of the transverse section U-shaped like arranged comprising: cooperate、Ball 4、The interior rail 1 of transverse section U-shaped like、The middle rail 3(of transverse section U-shaped like removes described ball 4，Three kinds of described rails are extrustion of metals or rolling forming，Certainly，Described middle rail 3 also can make of nonmetal parts),Side walls on described outer rail 2 is formed the most respectively with the side walls on corresponding described interior rail 1 and is coated with cambered surface 5(of described ball 4 part surface and is also punching press or rolling forming is main) (such as prior art，Consider actual machining accuracy，So-called cambered surface 5 simply curvature approximates the cambered surface of described ball 4 surface curvature，Simultaneously，Contact while described ball 4 being crossed multi-surface for minimizing and produce too many friction，The actual surface curvature being slightly less than described ball 4 of described cambered surface 5 curvature) (separately note，Obvious described cambered surface 5 refers to the cambered surface that may the most effectively touch with described ball 4)，The arc-shaped slot rolled for described ball 4 is jointly surrounded to cooperate，Multiple described ball 4 all it is arranged at intervals with to play the effect of described ball retainer in described middle rail 3 side walls，The described side walls of described middle rail 3 is arranged in correspondence with between described outer rail 2 side walls and described interior rail 1 side walls，Described outer rail 2 carries out relative roll type with described interior rail 1 move by being spaced the described ball 4 of installation on described middle rail 3；Described outer rail 2, described middle rail 3, described interior rail 1 are the structure around the bending of same axis circular arc, described axis is in described outer rail 2, described middle rail 3, the same side of described interior rail 1 the degree direction being parallel to slide rail, and the relative movement orbit of described middle rail 3, described outer rail 2 and/or described interior rail 1 is the circular arc camber line around this same described axis；That is, be equivalent to all by this same described axis, the rail described inside and outside, middle of generic linear slide rail is carried out circular arc bending forming.In the transverse section being perpendicular on slide rail length direction, described ball 4 ball surface diameter corresponding vertex on slide rail thickness direction is some a and some b, and described ball 4 ball surface diameter corresponding vertex on slide rail width is some c and some d；
Obvious complete class is compared with technology (including two its reality of this slide rail mounting arrangements (seeing Fig. 4) in bracing frame central post 8 inner chamber) above, therefore be not required to describe in detail again, and it is the shortcoming overcoming prior art, the most here must with prior art distinguish be also the most important feature of the present invention be (seeing Fig. 3),: in described in this slide rail the described cambered surface 5 of rail 1 extend always and cross a point on described ball 4 surface and c point and formation to this cladding of 2 (that is, described cambered surface 5 must walk around respectively these 2 some be coated with formation cambered surface)；The described cambered surface 5 of described outer rail 2 extend always and cross the b point on described ball 4 surface and d point and formed to this cladding of 2 (that is, described cambered surface 5 must walk around respectively these 2 some to form cambered surface cladding)；nullSo，It is coated with described a point and described b point can guarantee that the contact point of described ball 4 and described interior rail 1 and described outer rail 2 can fall all the time and rolls within described cambered surface 5，This is because，The two endvertexs the most described a point of described ball 4 ball surface diameter line on slide rail thickness direction and b point are now because being revealed all the details by the cambered surface of a small amount of area in described cambered surface 5 local、Cladding、" barb "，Obviously，When described ball 4 pushed by described interior rail 1 and described outer rail 2 move to slide rail thickness direction time，Described ball 4 can be because being constrained in being in the cladding face, cambered surface 5 local of the direction，The most all the time this local being wrapped by cambered surface 5 " at the bottom of arc " is pressed to the direction determined，And just because of this cladding、Overhead kick effect，Described ball 4 is made to be able near this local cambered surface 5 one point (though not in the middle part of described cambered surface 5) stabilized (similar indifferent equilibrium) with the contact point of described interior rail 1 or described outer rail 2，Make contact point occur in the most rough edge of described slide rail carry out scroll-up/down without moving about to described cambered surface 5 edge all the time after being pushed out as prior art again.Therefore, being adjusted, improve described cambered surface 5 position that cloth postpones and avoid the problem that prior art construction exists, make slide rail roll the most smooth, resistance when lifting the most uniformly, it is good that display lifts feel.Also it is, therefore, apparent that note the cladding face expanding described cambered surface 5 as far as possible to described a, b point when allowing in structure.
And simultaneously, see Fig. 3, be coated with described c point and described d point the most predominantly ensures that described interior rail 1 will not be deviate from from described outer rail 2；This is obvious, because, when described interior rail 1 and described outer rail 2 are in slide rail thickness direction stress, described interior rail 1 described cambered surface 5 thereon has had passed past described ball 4 and has been coated with (catching on) (even a small amount of local cambered surface 5) along constituting the cambered surface 5 to c point at the spherical diameter two summit c point in slide rail degree direction, in like manner, described outer rail 2 described cambered surface 5 thereon has also had passed past described ball 4 and has been coated with (catching on) (even a small amount of local cambered surface 5) along constituting the cambered surface 5 to d point at the spherical diameter summit d point in slide rail degree direction, so due to mutual backstop, can ensure that described interior rail 1 is by drawing along slide rail thickness direction or will not deviate from from described outer rail 2 during motive force, obviously this is the most critically important.In like manner, it is clear that the above-mentioned cladding face scope to described c, d point is the biggest more favourable, therefore, the area being coated with as far as possible under conditions of structure allows is more greatly.
Another from aforementioned, see Fig. 3, due to naturally needing of structure, the side walls of described middle rail 3 is always between the side walls of described outer rail 2 and described interior rail 1, obvious for this, after the hinge structure variation of described cambered surface 5 position, described middle rail 3 both sides, for keeping, be spaced the side walls of described ball 4 also should follow the change in location of described cambered surface 5 in the side walls of described outer rail 2 and described interior rail 1 correspondingly to carry out deviation change and occupy the most all the time therebetween with guarantee accordingly, make described ball 4 can occupy between described interior rail 1 and described outer rail 2 and normally roll.
Slide rail of the present invention is under the component effect that the upper and lower motive force of display partical gravity and personnel produces, described ball 4a is in the part of described cambered surface 5 and reveals all the details, part cladding (though not being the cladding that area is the biggest), part is by the position of " barb ", the contact point making described ball 4 can automatically reply (indifferent equilibrium) by means of power all the time and stably in described cambered surface 5, (though not in the middle part of described cambered surface 5) rolls, make ball will not as prior art the most uni-directionally edge to described cambered surface 5 vacillate, make lifting roll time the most smooth, resistance is the most uniform, display lifting feel is good, simultaneously, interior rail also will not be deviate from from outer rail, slide rail thickness also can be made thinner further simultaneously, be conducive to meeting the fashion requirement that people are thinner to complete machine column.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
