Description
Technical field
The utility model relates to physics experiment teaching field, in particular to a kind of convex lens tester.
Background technique
The equipment of existing research convex lens only has camera model, it can only study camera imaging situation, nothing
Method realizes the experiment of projector imaging contexts and the experiment of magnifying glass imaging contexts simultaneously, and student can not operate personally, is unfavorable for student
To the imaging contexts comprehensive understanding of convex lens and grasp.
Summary of the invention
In view of the deficienciess of the prior art, the purpose of the utility model is to provide a kind of convex lens testers.
The technical scheme adopted by the utility model is a kind of convex lens tester, including convex lens, optical screen and hand
Torch is characterized in that, further includes body shell, flexible lens barrel, plate and flashlight lens barrel, the convex lens, Telescopic mirror
Cylinder, body shell, plate, flashlight lens barrel and flashlight connect according to this；Described body shell one end is equipped with externally threaded
The other end of interconnecting piece, body shell is equipped with bracket；The flexible lens barrel is hollow both ends open structure, hollow cavity one
End is equipped with the internal screw thread cooperated with body shell interconnecting piece；Flashlight lens barrel is flower-shaped in loudspeaker；The lower end of convex lens is equipped with handle；
Flexible lens barrel is spirally connected with the interconnecting piece of internal screw thread one end and camera case, and the lens barrel other end that stretches connects convex lens,
Optical screen is plugged on the bracket of body shell, forms analogue camera component；
The illumination end of flashlight and flashlight lens barrel one end interference fit connect, and the flared end of flashlight lens barrel connects plate,
There is loophole, transparency is connect with plate, and transparency is mounted in the loophole of plate, and plate is mounted on fuselage on plate
On the bracket of shell, the interconnecting piece of body shell is successively connect with flexible lens barrel and convex lens, forms simulated projections instrument component.
In above scheme, convex lens is removably attachable to together with handle.
The beneficial effects of the utility model are: the convex lens tester, cooperatively forms amplification for convex lens and handle
Device cooperatively forms photomoduel with body shell and optical screen, cooperatively forms projector component with body shell and flashlight, respectively
Magnifying glass imaging, camera imaging and projector imaging are realized, the structure is simple, operates convenient for student, and imaging process is straight
It sees and the imaging characteristics of convex lens under different situations is vividly understood and grasped convenient for student.

Specific embodiment
Keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing 1 and Fig. 2
The utility model is described in further detail with specific embodiment.
Convex lens tester in the present embodiment, including convex lens 1, the flexible lens barrel 2, machine to link together according to this
Body shell 3, plate 5, flashlight lens barrel 6 and flashlight 7.3 one end of body shell, which is equipped with, has externally threaded interconnecting piece 31, body housing
The other end of body 3 is equipped with bracket 32.Flexible lens barrel 2 is hollow both ends open structure, and hollow cavity one end is equipped with and body housing
The internal screw thread of 3 interconnecting piece 31 of body cooperation.Flashlight lens barrel 6 is flower-shaped in loudspeaker.The lower end of convex lens 1 removably connects handle 11.
Flexible lens barrel 2 is spirally connected with internal screw thread one end and the interconnecting piece 31 of body shell 3, and 2 other end of lens barrel bonding of stretching is convex
Lens 1 connect optical screen made of frosted glass at the bracket 32 of body shell 3, form analogue camera component.
The illumination end of flashlight 7 and 2 one end of flashlight lens barrel interference fit connect, and the flared end connection of flashlight lens barrel 2 is inserted
Plate 5 has loophole 51 on plate 5, and transparency 4 is connect with plate 5, and transparency 4 is mounted in the loophole 51 of plate 5,
Plate 5 is mounted on the bracket 32 of body shell 3, and the interconnecting piece 31 of body shell 3 connects with flexible lens barrel 2 and convex lens 1 according to this
It connects, forms simulated projections instrument component.
Convex lens, camera and projector collection are integrated by the convex lens tester in the present embodiment, first will
Flexible lens barrel is mounted on body shell, and then the convex lens with handle is mounted on flexible lens barrel.Optical screen is inserted into fuselage
In the subsequent bracket of shell, the research of camera imaging situation can be carried out.
When carrying out the research of projector imaging contexts, first transparency is mounted on plate, plate is inserted into body shell
In subsequent bracket, the research of projector imaging can be completed.
When amplifying the research of mirror imaging contexts, it will be unloaded down with the convex lens slave with handle, can be used as putting
Big mirror realizes the research of magnifying glass imaging contexts.
