Abstract
The invention provides a shifting rotational device. A product provided with the shifting rotational device has larger rotation range and is more reliable. All the parts of the shifting rotational device are arranged on inner sides of the mounted object so that the product has more beautiful appearance, and in addition, an outer surface is convenient to clean so that the product is improved in competitiveness. The shifting rotational device includes a rotating arm A, a rotating shaft A, a connection arm, a rotating shaft B and a rotating arm B. One end of the rotating arm A and one end of the connection arm are respectively provided with rotating shaft sleeves which are matched with the rotating shaft A. One end of the rotating arm B and the other end of the connection arm are respectively provided with rotating shaft sleeves which are matched with the rotating shaft B. The rotating arm A is rotatably connected to the connection arm through the rotating shaft A and the rotating arm B is rotatably connected to the connection arm through the rotating shaft B. The connection arm is bent to form a certain angle.
Description
Technical field
The present invention relates to mechanical part, especially relate to a kind of displacement slewing gear.
Background technique
The slewing gear of prior art, sways mostly, and it is in rotation process, and shaft core position is relatively fixing.As hinge be by two panels separately independently vane hinge form, be equipped with between two blades rotating shaft, rotating shaft cover form hinging structure.This hinge can make the object be fixed in its two hinge rotate in certain space, but blade and rotating shaft cover lay respectively at the inside and outside both sides of filled object, always has part will be exposed to outside, its overall appearance is affected, and is unfavorable for that outer surface cleans.
Summary of the invention
For overcoming the defect that above-mentioned prior art exists, the invention provides a kind of displacement slewing gear, make the rotatable amplitude of the product being provided with this displacement slewing gear more greatly and more reliable, and make each several part of this displacement slewing gear all be positioned at the inner face of institute's articles, make the outward appearance of product more attractive in appearance, and be convenient to outer surface and clean, thus the grade of improving product, improve product competitive ability.
The technological scheme that technical solution problem of the present invention adopts is: a kind of displacement slewing gear, comprise pivoted arm A, rotating shaft A, link arm, rotating shaft B, pivoted arm B, one end of described pivoted arm A and one end of described link arm are provided with the rotating shaft cover with described rotating shaft A adaptation, one end of described pivoted arm B and the other end of described link arm are provided with the rotating shaft cover with described rotating shaft B adaptation, described pivoted arm A and described link arm are rotatably connected by described rotating shaft A, described pivoted arm B and described link arm are rotatably connected by described rotating shaft B, and described link arm has a certain degree through bending shape
θ.
Further, 60 degree≤
θ≤ 120 degree.
Further,
θ=90 degree.
Working principle of the present invention is, shown in Fig. 3 and Fig. 4, the inner face of one end of object one to be installed is fixedly connected with pivoted arm A by link, and the inner face of one end of object two to be installed is fixedly connected with pivoted arm B by link, and makes described angle
θto inwardly projecting, described rotating shaft cover is also towards interior, object to be installed one is fixed, when electronic or when manually making object two to be installed rotate, described link arm around the shaft B rotates, described connection link arm rotates around described rotating shaft A simultaneously, be exposed between described object to be installed one and object to be installed two or outside without rotating shaft cover or other assemblies in rotation process, therefore make product appearance more beautiful, and owing to having two rotating shaft, the rotation degree of convergence of object two to be installed larger, thus reach object of the present invention.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention stereogram.
Fig. 2 is embodiment of the present invention side sectional view.
Fig. 3 is that the embodiment of the present invention stretches using state.
Fig. 4 is that the embodiment of the present invention bends straight using state.
In figure 1, pivoted arm A, 2, rotating shaft A, 3, link arm, 4, rotating shaft B, 5, pivoted arm B, 6, object to be installed, 7, object to be installed two.
Embodiment
A kind of displacement slewing gear, comprise pivoted arm A1, rotating shaft A2, link arm 3, rotating shaft B4, pivoted arm B5, one end of described pivoted arm A1 and one end of described link arm 3 are provided with the rotating shaft cover with described rotating shaft A1 adaptation, one end of described pivoted arm B5 and the other end of described link arm 3 are provided with the rotating shaft cover with described rotating shaft B4 adaptation, described pivoted arm A1 and described link arm 3 are rotatably connected by described rotating shaft A2, described pivoted arm B5 and described link arm 3 are rotatably connected by described rotating shaft B4, and described link arm 3 has a certain degree through bending shape
θ.
Further, 60 degree≤
θ≤ 120 degree.
Further,
θ=90 degree.
