Utility model content
The purpose of this utility model is to provide a kind of simple optical image-forming principle demonstrator, solves optical demonstration instrument for teaching device function singleness of the prior art, awkward problem.
The technical scheme that the utility model adopts is: a kind of simple optical image-forming principle demonstrator, comprise chute, five slide blocks are connected with in chute, the upper surface of five slide blocks is all fixed with expansion link, the upper end of five expansion links is fixed with light source, convex lens respectively, concavees lens, riser and optical screen, riser has the aperture penetrating riser, and optical screen, riser, concavees lens and convex lens are all just arranged light source.
Feature of the present utility model is also:
Five slide blocks are followed successively by slide block a, slide block b, slide block c, slide block d, slide block e from one end of chute to the other end, light source, convex lens, concavees lens, riser and optical screen are connected in the expansion link upper end be connected with slide block a, slide block b, slide block c, slide block d, slide block e respectively.
Expansion link comprises montant a and montant b, and montant b is hollow structure, and montant b coaxial sleeve is connected on the outside of montant a, montant b has threaded hole, is provided with holding screw in threaded hole, and montant a and montant b is connected by holding screw; Light source, convex lens, concavees lens, riser and optical screen are fixed in the upper end of corresponding montant b respectively.
Aperture is arranged on the center position of riser.
The beneficial effects of the utility model are: a kind of simple optical image-forming principle of the utility model demonstrator, by chute, being connected and the setting of expansion link of slide block, multiple optical device can be integrated on a demonstrator and the position of the optical device easily adjustable telescopic rod connected, phase mutual edge distance and height, to efficiently solve optical demonstration instrument for teaching device function singleness of the prior art, awkward problem.

In figure, 1. chute, 2. slide block a, 3. slide block b, 4. slide block c, 5. slide block d, 6. slide block e, 7. expansion link, 7-1. montant a, 7-2. montant b, 7-3. holding screw, 8. light source, 9. convex lens, 10. concavees lens, 11. risers, 12. apertures, 13. optical screens.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail:
A kind of simple optical image-forming principle of the utility model demonstrator, as shown in Figure 1, comprise chute 1, five slide blocks are connected with in chute 1, five slide blocks are followed successively by slide block a2 from one end of chute 1 to the other end, slide block b3, slide block c4, slide block d5, slide block e6, the upper surface of five slide blocks is all fixed with expansion link 7, with slide block a2, slide block b3, slide block c4, slide block d5, the expansion link 7 that slide block e6 is connected is fixed with light source 8 respectively, convex lens 9, concavees lens 10, riser 11 and optical screen 13, riser 11 has the aperture 12 penetrating riser 11, aperture 12 is arranged on the center position of riser 11.Optical screen 13, riser 11, concavees lens 10 and convex lens 9 are all just arranged light source 8.Expansion link 7 comprises montant a7-1 and montant b7-2, montant b7-2 is hollow structure, and montant b7-2 coaxial sleeve is connected on the outside of montant a7-1, and montant b7-2 has threaded hole, be provided with holding screw 7-3 in threaded hole, montant a7-1 and montant b7-2 is connected by holding screw 7-3; Light source 8, convex lens 9, concavees lens 10, riser 11 and optical screen 13 are fixed in the upper end of corresponding montant b7-2 respectively.
Candle can be used simply as light source 8, at the affixed disk in expansion link 7 upper end be connected with candle, then candle is placed on disk.During use, slide five slide blocks, can adjust the distance between each element as required; Unclamp holding screw 7-3, the height of sliding vertical member b7-2 and adjustable expansion link 7, tighten holding screw 7-3 after adjusting to proper height again and position.When certain or certain several element does not need, such as when demonstrating pinhole imaging system principle, not needing to use convex lens 9 and concavees lens 10, so unclamping holding screw 7-3, montant b7-2 is taken away together with convex lens 9 affixed on it, concavees lens 10; And by being installed to the mode on another one montant a7-1 after being taken down by a montant b7-2 again, light source 8, convex lens 9 arbitrarily can be exchanged, the position of concavees lens 10, riser 11 and optical screen 13.Therefore on this demonstrator, just can realize the image-forming principle that convex lens imaging principle, concavees lens image-forming principle, pinhole imaging system principle and convex lens coordinate concavees lens.Image-forming principle demonstrator of the present utility model, although do not reach point-device degree in distance and adjustment highly, but its structure is simple, easily make, easy to operate, the teaching request about optical imaging concept in Middle School Physics can be met completely, there is good promotional value.
