Abstract
The utility model discloses an arc slide rail. The arc slide rail comprises an external slide rail, an inner slider ail contained in the external slide rail, a roller bracket clamped between the external slide rail and the inner slide rail, and a roller arranged on the roller bracket; two sides of the roller are respectively connected with the external slide rail and the inner slide rail; the external slide rail and the inner slide rail are arc-shaped so as to realize the arc rotation of other parts arranged on the external rail and the internal rail; and two parts are unfolded in a determined angle so that the hinge point of the parts is not on the device, and the aim that the two parts are tightly combined without interfering each other is achieved.
Description
Technical field
The utility model relates to a kind of slide rail, especially a kind of slide rail with improvement structure.
Background technique
Along with the development of modern industry, the validity of relative movement component, aesthetics etc. are had higher requirement.In industry, often need two component along the mutual displacement of track that sets or move.Motion link commonly used has line slide rail and hinge etc.But these links all have its narrow limitation, for example, line slide rail can only be realized the straight line motion of two parts, hinge since its rotation hinge often design from it, so want to realize that hinge is not only attractive in appearance but also can make the close contact of two component relatively more difficult, and its movement locus is subjected to the ectocines such as gravity larger, is difficult to realize the precise motion of component.
So, need a kind of new technological scheme to address the above problem.
The model utility content
The purpose of this utility model is the deficiency that exists for prior art, and a kind of circular arc slide rail is provided, and can be mounted between two component that need rotary moving, reaches two accurate circular arcs of parts and rotates.
For realizing above-mentioned model utility purpose, the utility model circular arc slide rail can adopt following technological scheme:
A kind of circular arc slide rail comprises external sliding rail, is contained in interior slide rail in the external sliding rail, is located in the roller bracket between external sliding rail and the interior slide rail and is installed on roller on the roller bracket, and the both sides of described roller cooperate with external sliding rail and interior slide rail respectively; Described external sliding rail and interior slide rail are circular-arc.
Compare with background technique, external sliding rail and the interior slide rail of the circular arc type that the utility model circular arc slide rail cooperatively interacts by setting, can realize that the circular arc that is installed on other component on external sliding rail and the interior slide rail rotates, two angles that component launch to set, make between component hinge not at equipment self, thereby can reach that two parts are combined closely but the purpose that do not interfere with each other.
Description of drawings
Fig. 1 is the structural representation of the utility model circular arc slide rail.
Fig. 2 is along the sectional view of A-A direction among Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
See also Figure 1 and Figure 2, the utility model discloses a kind of circular arc slide rail 100, comprises external sliding rail 20, is contained in interior slide rail 30 in the external sliding rail 20, is located in the roller bracket 40 between external sliding rail 20 and the interior slide rail 30 and is installed on roller 50 on the roller bracket 40.The both sides of described roller 50 cooperate with external sliding rail 20 and interior slide rail 30 respectively, and described external sliding rail 20 and interior slide rail 30 are circular-arc.Described external sliding rail 20 has the rail slot 21 of accommodating interior slide rail 30 and roller bracket 40, convexes with positive stop 22 in the described rail slot 21, and described interior slide rail 30 is provided with restraining groove 31 that cooperate with positive stop 22 and that extend along interior slide rail 30 bearing of trends.
Described roller bracket 40 is I shape, and described roller 50 spread configurations are in the both sides of interior slide rail 30.In the present embodiment, described roller 50 is cylindrical roller, and cylindrical roller makes interior external sliding rail reach motion precision, flexible, the stressed uniform purpose of rotation in roller bracket 40 interior even distributions.The cylindrical roller of installing between interior external sliding rail can provide larger strength in the centrifugal force direction compared to ball, and friction factor is little, and interior external sliding rail Location accuracy is high.Can realize perpendicular to the surface of revolution direction stressed by changing cylindrical roller with angle perpendicular to the surface of revolution direction.
The end that described interior slide rail 30 extends external sliding rail 20 is provided with interior slide rail mounting hole 32.The bottom surface of described external sliding rail 20 is provided with some external sliding rail mounting holes 23 along external sliding rail 20 bearing of trends.During installation, external sliding rail 20 is fixed on the component by uniform external sliding rail mounting hole 23, interior slide rail 30 is fixed on another component that need to rotatablely move by interior slide rail mounting hole 32.When the motion of two component since rotating center G point not at component self, therefore the motion of two component can not interfered mutually, unfolded is freely accurate flexibly, and two component can realize that the plane closely connects when folding.
In sum, the utility model is designed to circular shape with slide rail, and utilizes cylindrical roller to be transmission connection piece, and its advantage is: the first, can realize that hinge is that rotating center is away from mutual motion component.The second, slide rail can be installed on component inside, and realize that component rotate mutually, namely rotary connector be can't see in the outside, reaches product purpose attractive in appearance.The 3rd, by cylindrical roller being installed as interior external sliding rail link, can bear the larger power of centrifugal force direction.The 4th, by changing cylindrical roller and can making bearing thrust on the slide rail surface of revolution direction perpendicular to the surface of revolution orientation angle.The 5th, slide rail utilizes the roller transmission friction factor little, and Location accuracy is high.The 6th, by changing the adjustment of the positive stop realization expanded angle between the interior external sliding rail.The 7th, rail structure simply is easy to processing and produces in enormous quantities.
