Abstract
The utility model relates to a kind of arc-shaped slide rail, comprise the outer rail cooperatively interacting and arrange, middle rail, interior rail, be arranged between described outer rail and described interior rail at described middle rail, described middle rail two wall side is provided with ball or roller, undertaken moving relative to rolling by described middle rail between described outer rail with described interior rail, it is characterized in that: described outer rail, described middle rail, described interior rail is at least the arc-shaped structure around same axis in the length section of phase mutual relative movement, described axis is at described outer rail, described middle rail, the same side of described interior rail is also parallel to the thickness direction of slide rail, outer rail described in it and described interior rail and described middle rail movement locus are the circular arc camber line around described axis.The utility model improves by only having dull straight-line trajectory for existing slide rail.Make slide rail can realize arc trajectory sliding effect, the supporting frame with circular motion track requirements can be applicable to, and when can ensure that slide rail moves, integrated carrying ability still can be comparatively even.
Description
Technical field
A kind of arc-shaped slide rail of the utility model relates to display bracket technical field, particularly relates to the rail structure technology in the supporting frame that need be elevated.
Background technique
At present, flourish along with Digital A/V, the utilization of liquid crystal display is extremely extensive, and the use overwhelming majority of display device need be equipped with corresponding supporting frame, with supporting display screen.And supporting frame often needs lifting, and lifting structure generally all needs slide rail to reduce the surface friction drag of OQ t movement parts, along with supporting the use in a large number of supporting frame, has nowadays developed multiple linarity slide rail, and its utilization is also increasingly extensive.So-called slide rail is with the ball on middle rail, and roller, as the transmission intermediary of outer rail and interior rail, is rolling friction when making outer rail and interior rail make relative linear reciprocating motion, thus reaches the transmission object of low friction.
But existing slide rail on market, its sliding trace is straight line motion, and movement locus is dull, can not adapt to the special requirement that supporting frame elevating movement is curve.
Summary of the invention
For the deficiency that prior art exists, the utility model object is providing a kind of arc-shaped slide rail, and its movement locus can be circular arc line.
To achieve these goals, the utility model realizes by the following technical solutions:
A kind of arc-shaped slide rail, comprise the outer rail, middle rail, the interior rail that cooperatively interact and arrange, be arranged between described outer rail and described interior rail at described middle rail, described middle rail two wall side is provided with ball or roller, undertaken moving relative to rolling by described middle rail between described outer rail with described interior rail, it is characterized in that: described outer rail, described middle rail, described interior rail are at least the arc-shaped structure around same axis in the length section of phase mutual relative movement
describedaxis described outer rail, described middle rail, described interior rail same side and be parallel to the thickness direction of slide rail, outer rail described in it and described interior rail and described middle rail movement locus are the circular arc camber line around described axis.
The utility model is by improving for existing line slide rail, make slide rail can realize movement in a curve track, can be applicable to the lifting support frame with circular motion track requirements, and when can ensure that slide rail moves, integrated carrying ability still can be comparatively even by ball or roller.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth further, describing the utility model in detail.
See Fig. 1, a kind of arc-shaped slide rail, comprise the outer rail 1, middle rail 2, the interior rail 3 that cooperatively interact and arrange, described middle rail 2 is arranged between described outer rail 1 and described interior rail 3, described middle rail 2 liang of wall sides are provided with in ball or roller 4(Fig. 1 and carefully do not draw), undertaken moving relative to rolling by described middle rail 2 between described outer rail 1 with described interior rail 3, these rail structures are all adopted as the very general known features in related domain and technology, therefore do not repeat; But it is characterized in that: described outer rail 1, described middle rail 2, described interior rail 3 be at least in the length section of phase mutual relative movement around same axis arc-shaped structure (be namely equivalent to generic linear slide rail each outer in rail carry out bending around the circular arc of described same axis the shape of rear formation) (obviously, section without relative movement can not need circular arc, certainly these sections have been the equal of formal structure)
describedsame axis described outer rail 1, described middle rail 2, described interior rail 3 same side and be parallel to the thickness direction of slide rail, outer rail 1 described in it and described interior rail 3 and described middle rail 2 movement locus are circular arc camber line around same described axis (see Fig. 1, the thickness direction of this slide rail is perpendicular to paper, described axis is also perpendicular to paper, the bending direction that described slide rail is each, for around this same described axis).This routine described outer rail 1, described middle rail 2, described interior rail 3 all adopt impact briquetting, and because all wanting circular arc to bend, therefore on it, all attaching holes, the isostructural position of groove also all should adjust accordingly by circular arc direction, and this is obvious, therefore does not repeat.Also because described middle rail 2 is also arc-shaped structure, obviously, described middle rail 2 liang of wall sides because of radius different, therefore the pitch-row in the hole of the accommodating described ball in its both sides or roller 4 can not wait.
The utility model is by improving for existing line slide rail, make slide rail can realize movement in a curve track, can be applicable to the lifting support frame with circular motion track requirements, and when can ensure that slide rail moves, integrated carrying ability still can be comparatively even by ball or roller.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
