Description
Technical field：
The present invention relates to projector for real object structure-design technique field, especially a kind of projector for real object armed lever.
Background technology：
Projector for real object is widely used in teaching, speech, exhibition and various meetings.Projector for real object, which generally comprises, " to be taken the photograph
As head ", the parts such as " armed lever " and " demo platform ".It in demonstration, is demonstrated object and is placed on demo platform, by adjusting camera
The hinge angle between hinge angle and demo platform and armed lever between armed lever, can make camera in the plane with demo platform vertical
Interior translation or rotation make camera be demonstrated object by special angle alignment, and the picture signal taken are exported to projection
Instrument etc. shows equipment.But when mobile armed lever, needs to adjust the hinge angle between camera and armed lever manually, can just make camera and put down
Angle between platform remains unchanged, and especially when projector for real object is used to show the view of object special angle, moving object is thrown
The hinge angle between camera and armed lever is frequently adjusted after shadow instrument armed lever, it is difficult to which the angle for accurately controlling camera influences to drill
Show and teaching efficiency.
Invention content：
In view of the above problems existing in the prior art, the purpose of the present invention is to provide a kind of reasonable design, it is safe and reliable,
The projector for real object armed lever of camera angle is passively adjusted by mechanical structure.
The technical problems to be solved by the invention are realized using following technical scheme.
A kind of projector for real object armed lever, including pedestal, the first torsional moment hinge, the first armed lever, the first armed lever secondary bar, the second torsion
Square hinge, the second armed lever, the second armed lever secondary bar, link, camera torsional moment hinge holder, camera.It is characterized in that：The pedestal
Holder equipped with the first torsional moment hinge of installation, the first armed lever secondary bar, first torsional moment hinge one end is mounted on by screw
On the holder of pedestal, the other end is mounted on the lower end of the first armed lever by screw；Institute's second torsional moment hinge one end passes through spiral shell
Nail is mounted on the lower end of the second armed lever by screw mounted on the upper end of the first armed lever, the other end；The Change-over frame passes through screw
On the second torsional moment hinge；The first armed lever secondary bar both ends are mounted on base support and Change-over frame by screw respectively
On；The second armed lever secondary bar both ends are separately mounted to by screw on Change-over frame and camera torsional moment hinge holder；State second
The upper end of armed lever is equipped with the through-hole of installation camera torsional moment hinge holder；The camera torsional moment hinge holder cylindrical side passes through the second arm
Bar upper end through-hole is simultaneously installed with screw, and flange side is mounted on by screw on camera.
Compared with prior art, the beneficial effects of the invention are as follows:A kind of projector for real object armed lever have it is simple in structure, at
The features such as this is low, easy to operate, stability is good, flexibility is high, using the folding structure of double armed lever, makes the phase of projector for real object
Machine has the activity space of bigger；By arrange four bar mechanical mechanism of double parallel quadrangle avoid in camera translational motion camera with
The variation of angle between pedestal, realizes the movement of the translation of camera, compared to the angle between servos control armed lever and camera
Method, have the characteristics that at low cost, mechanical mechanism passively control, structure it is reliable.
Description of the drawings：
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the Change-over frame structure and scheme of installation of the present invention；
Fig. 3 is the camera torque supporting structure and scheme of installation of the present invention.
In figure：1, pedestal；2, the first torsional moment hinge；3, the first armed lever secondary bar；4, the first armed lever；5, Change-over frame；6, second
Torsional moment hinge；7, the second armed lever secondary bar；8, the second armed lever；9, camera torsional moment hinge holder；10, camera.
Specific implementation mode：
In order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand, tie below
Specific embodiment and diagram are closed, the present invention is further explained.
Shown in attached drawing 1~3, a kind of projector for real object armed lever, including pedestal 1, the first torsional moment hinge 2, the first armed lever
Secondary bar 3, the first armed lever 4, link 5, the second torsional moment hinge 6, the second armed lever secondary bar 7, the second armed lever 8, camera torsional moment hinge branch
Frame 9, camera 10.It is characterized in that：Holder of the pedestal 1 equipped with the first torsional moment hinge 2 of installation, the first armed lever secondary bar 3, institute
It states 2 one end of the first torsional moment hinge to be mounted on by screw on the holder of pedestal 1, the other end is mounted on the first armed lever 4 by screw
Lower end；Described second torsional moment hinge, 6 one end the upper end of the first armed lever 4 is mounted on by screw, the other end pacified by screw
Mounted in the lower end of the second armed lever 8；The Change-over frame 5 is mounted on by screw on the second torsional moment hinge 6；The first armed lever secondary bar
3 both ends are mounted on by screw on 1 holder of pedestal and Change-over frame 5 respectively；Second armed lever secondary bar, 7 both ends pass through screw point
It An Zhuan not be on Change-over frame 5 and camera torsional moment hinge holder 9；The upper end for stating the second armed lever 8 is equipped with installation camera torsional moment hinge
The through-hole of holder 9；9 cylindrical side of camera torsional moment hinge holder passes through 8 upper end through-hole of the second armed lever and is installed with screw, flange
Side is mounted on by screw on camera 10.
The present invention use two groups of parallelogram four-bar mechanism, pedestal 1, the first torsional moment hinge 2, the first armed lever secondary bar 3,
First armed lever 4, link 5 form first group of parallelogram four-bar mechanism, and Change-over frame 5 and the relative angle of pedestal 1 is made to keep
It is constant；The link 5, the second torsional moment hinge 6, the second armed lever secondary bar 7, the second armed lever 8, camera torsional moment hinge holder 9 form
Second group of parallelogram four-bar mechanism keeps camera torsional moment hinge holder 9 constant with the relative angle of Change-over frame 5；Two group of four bar
Mechanism makes the relative angle between camera torque holder 9 and pedestal 1 remain unchanged, i.e., need not adjust camera torsional moment hinge 9
Angle can just make camera 10 constant relative to the special angle of object.
In use, the angle that special angle is formed between camera 10 and pedestal 1 can be made by adjusting camera torsional moment hinge 9,
When mobile camera 10, it is only necessary to which mobile second armed lever 8 can just be such that camera is translated in zone of action, need not readjust
Camera torsional moment hinge 9 is it is ensured that camera 10 and the angle of object remain unchanged.
