Description
Technical field
The utility model relates to a kind of whirligig of rotary angle controllable.
Background technique
The functional requirement of rotation or left-right rotation before and after flat panel display product in the market all has in order to reach this purpose, generally all adopts a cover whirligig to control its angle of swing.Existing whirligig comprises base support, rotating shaft and two links, the both sides of base support respectively are provided with a connecting sheet, two links lay respectively at the both sides of base support, be equipped with axis hole on two links and two connecting sheets, rotating shaft is passed axis hole and base support is connected with link; Be provided with position-limitting mouth on connecting sheet, be provided with spacing journal stirrup on base support, spacing journal stirrup snaps in the position-limitting mouth, be used to control the angle of swing between base support and the link, but there is following defective in this structure:
1. the precision of the single-piece work of two parts is difficult to control, so the control of rotating shaft angle of swing is difficult to reach requirement;
2. strengthen the requirement of production technology and packaging technology, increased cost.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of whirligig of rotary angle controllable is provided, and control accuracy of the present utility model is higher, and manufacturing cost is low.
Its technological scheme is as follows:
A kind of whirligig of rotary angle controllable, comprise base support, rotating shaft and two links, the both sides of base support respectively are provided with a connecting sheet, two links lay respectively at the both sides of base support, be equipped with axis hole on two links and two connecting sheets, rotating shaft is passed axis hole and base support is connected with link; On rotating shaft and axis hole, be equipped with confined planes, and the confined planes of rotating shaft is corresponding with the confined planes of axis hole.
The utility model can adopt the mode of punching press to process because rotating shaft and axis hole are provided with confined planes, and manufacturing cost is low; Adopt impact style processing confined planes, machining accuracy is easy to control, when rotating shaft is rotated, and the scope rotation that can only set.
The technological scheme of the further refinement of aforementioned techniques scheme can be:
Confined planes in the described rotating shaft is two, and two confined planes are with respect to the axis symmetry of rotating shaft; Corresponding, the confined planes on the described axis hole also is two.Be equipped with two confined planes in each rotating shaft, reduce the confined planes distortion and to the influence of angle, control accuracy is higher.
Confined planes in the described rotating shaft is the plane, and the confined planes on the described axis hole is to projecting inward and form the butterfly hole.Axis hole is the shape in butterfly hole, and is little to the wearing and tearing of axis hole during the rotating shaft rotation.
Described rotating shaft is two, and the link and the connecting sheet of base support both sides passed in each rotating shaft respectively.
This whirligig also includes adjusting nut, and first end of described rotating shaft is provided with spacing termination, and second end is provided with screw thread, and nut is connected with screw-thread fit.Can regulate degree of tightness between base support and the link by adjusting nut, and and then the resistance size when regulating rotation.
On described link and base support, be equipped with fixed hole.Can be connected with other parts by fixed hole.
In sum, the utility model has the advantages that: control accuracy of the present utility model is higher, and manufacturing cost is low.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:
As shown in Figure 1 to Figure 3, a kind of whirligig of rotary angle controllable, comprise base support 1, rotating shaft 2 and two links 3, the both sides of base support 1 respectively are provided with a connecting sheet 4, two links 3 lay respectively at the both sides of base support 1, be equipped with axis hole 5 on two links 3 and two connecting sheets 4, rotating shaft 2 is passed axis hole 5 and base support 1 is connected with link 3; On rotating shaft 2 and axis hole 5, be equipped with confined planes 6, and the confined planes 6 of rotating shaft 2 is corresponding with the confined planes 6 of axis hole 5.
Wherein, the confined planes 6 in each rotating shaft 2 is two, and two confined planes 6 are with respect to the axis symmetry of rotating shaft 2, and corresponding, the confined planes 6 on the axis hole 5 also is two; Confined planes 6 in the rotating shaft 2 is the plane, and the confined planes 6 on the axis hole 5 is to projecting inward and form the butterfly hole.Rotating shaft 2 is two, and the link 3 and the connecting sheet 4 of base support 1 both sides passed in each rotating shaft 2 respectively.This whirligig also includes adjusting nut 7, and first end of rotating shaft 2 is provided with spacing termination 8, the second ends and is provided with screw thread 9, and nut and screw thread 9 are connected.On described link 3 and base support 1, be equipped with fixed hole 10.
Present embodiment can adopt the mode of punching press to process because rotating shaft 2 and axis hole 5 are provided with confined planes 6, and manufacturing cost is low; Adopt impact style processing confined planes 6, machining accuracy is easy to control, when rotating shaft 2 rotations, and the scope rotation that can only set; In addition, can regulate degree of tightness between base support 1 and the link 3 by adjusting nut 7, and and then the resistance size when regulating rotation.
Only be specific embodiment of the utility model below, do not limit protection domain of the present utility model with this; Any replacement and the improvement done on the basis of not violating the utility model design all belong to protection domain of the present utility model.
