Description
Technical field
The utility model relates to a kind of Physical Experiment teaching aid, particularly a kind of projector image-forming principle apparatus for demonstrating.
Background technology
In the past, the demonstration of projector image-forming principle completed by writing projector, but the Lights section of this projector is comparatively complicated and be arranged on the inside of machine, is unfavorable for student's observation.Afterwards, along with the modern quickening of general education instruments used for education, the original projector of writing using of many schools disappeared, and caused the difficulty of projector image-forming principle demonstration.Now this knowledge of study can only lean on projector image-forming principle on books to explain, due to demonstration that can not image out, cause very large inconvenience to classmates' understanding.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of design science rationally, be easy to classmates and understand, conveniently demonstrate, be easy to the projector image-forming principle apparatus for demonstrating of realizing.
The utility model solves its technical matters and takes following technical scheme to realize:
A kind of projector image-forming principle apparatus for demonstrating, it is characterized in that: by lamp socket, cone, bulb, projection plate, erecting frame, camera lens and catoptron, formed, middle part at lamp socket is provided with socket, bulb is installed on socket, outer cover at bulb is equipped with a cone, top at cone is equipped with projection plate, and on lamp socket, the sidepiece of socket is fixed with erecting frame, and on erecting frame, the positive top of projection plate regulates camera lens and catoptron are installed successively from bottom to up.
And described projection plate consists of plate body, projecting figure and maintenance pawl, is shaped with the projecting figure of hollow out at the middle part of plate body, in top and the bottom of the periphery plate body of projecting figure, maintenance pawl is installed, this maintenance pawl is installed in the cylinder of cone along upper.
And described bulb is an integrated bulb, this integrated bulb consists of the LED bulb of outer cover lampshade.
And described lampshade is opal glass lampshade.
And the height of described cone is higher than the height that is arranged on socket place bulb.
And described camera lens is magnifier.
Advantage of the present utility model and good effect are:
1. this projector image-forming principle apparatus for demonstrating, during use, switch on power, make bulb luminous, on cone, put projection plate, adjust the angle of catoptron, the projecting figure on projection plate is just in time impinged upon on optical screen (wanting metope or the screen of imaging), adjust again the height of camera lens, until there is projected image clearly on optical screen.Total is simple, be easy to realize, and can help the principle of understanding projector imaging of students image, is conducive to the study of students.
2. this projector image-forming principle apparatus for demonstrating, by the upper and lower surface at projection plate plate body, maintenance pawl is set, during use, projection plate can be placed respectively by tow sides, the difference that allows classmates observe the projecting figure institute's imaging on optical screen on different directions, facilitate that classmates understand more comprehensively, deep.
3. this projector image-forming principle apparatus for demonstrating, by being the integrated bulb of the outer outer cover milky lampshade of LED bulb by lamp envelope design, the projection of having avoided the picture because directly using LED bulb to make to be on optical screen mixing filament, has guaranteed imaging effect.
4. the utility model scientific structure design is reasonable, and have advantages of that the classmates of being easy to understand, convenience is demonstrated, imaging effect is good, be easy to realize, be a kind of projector image-forming principle apparatus for demonstrating with higher innovation.
