Convex lens is fixed in lens, three end of the telescopic rod, and prism is fixed in four end of the telescopic rod, and the display box top is close
The strut side is set into mirror hole, and entering Jing Kongchu described in the face of display box outside top passes through universal joint rotation connection behaviour
Make bar, the operating lever runs through the display box, and the operating lever is fixedly connected with laser pen in one end inside the display box.
Preferably, display box described in the top face of the strut it is described enter mirror hole.
Preferably, the toroidal frame is the straight-bar that two intersections are inscribed in a hollow ring, the shaft is fixed on two
In the crosspoint of root straight-bar.
Preferably, the display box is made of transparent glass or plastics.
Preferably, the base end face fixed idler whell, water injection hole is arranged in the display box top, and apopore is arranged in bottom end.
The utility model advantage：The utility model can not only show the light refraction process of different lens well, and
And can also show liquid refracting process, easy to use, demonstration is convenient, is very beneficial for demonstrating various Experiments of Optics to student.

Specific implementation mode
With reference to the attached drawing in new embodiment, the technical scheme in the embodiment of the utility model is carried out clear, complete
Whole description, it is to be understood that the scope of protection of the utility model is not restricted by specific implementation.
Referring to Fig.1, the utility model provides comprehensive optical demonstrator, including pedestal 1, strut 3 and display box 13, described
The strut 3 is fixed on pedestal 1 side by side and the display box 13, the top of the strut 3 are rotatablely connected toroidal frame by shaft
4, telescopic rod 1, telescopic rod 27, telescopic rod 39 and telescopic rod 4 11 are fixed on 4 edge of the toroidal frame respectively, it is described flexible
Concavees lens 8 are fixed in one 5 end fixed pan mirror 6 of bar, 27 end of the telescopic rod, and convex lens is fixed in 39 end of the telescopic rod
10, prism 12 is fixed in 4 11 end of the telescopic rod.
With reference to Fig. 2,13 top of the display box is set into mirror hole 14 close to 3 side of the strut, outside the display box 13
Enter described in face above portion at mirror hole 14 and operating lever 16 is rotatablely connected by universal joint, the operating lever 16 runs through the display box
13, the operating lever 16 is fixedly connected with laser pen 17 in 13 inside one end of the display box.
Enter mirror hole 14 described in display box 13 described in the top face of the strut 3.
The toroidal frame 4 is the straight-bar that two intersections are inscribed in a hollow ring, and the shaft is fixed on two straight-bars
Crosspoint on.
The display box 13 is made of transparent glass or plastics.
Water injection hole 15 is arranged in 1 bottom surface fixed idler whell 2 of the pedestal, 13 top of the display box, and apopore 18 is arranged in bottom end.
Operation principle：Comprehensive optical demonstrator provided by the utility model can be incited somebody to action by rotary annular frame when in use
It needs the lens face shown to enter mirror hole, then elongates telescopic rod, lens are stretched into display box, close the doors and windows and electric light, beat
Laser pen is opened, adjusts angle of incidence of light with operating lever, you can watch the refraction effect of different lens.
