Abstract

The utility model discloses a combined convex lens imaging demonstration instrument, which is composed of a left bracket 1, a right bracket 1', convex lenses 3, a screen 4 and a light source 5. The screen 4 and the light source 5 are respectively arranged on both sides of the convex lenses 3. A slide way 2 is fixed between the left bracket 1 and the right bracket 1'. A convex lens rotating bracket 6 is fixed at the middle of the slide way 2. Both sides of the slide way 2 are respectively provided with a screen sliding clamping block 7 and a light source sliding clamping block 8. The front board surface of the slide way 2 is provided with a scale 9. The different convex lenses 3 are respectively arranged in corresponding lens inserting frames 63 of the convex lens rotating bracket 6. The screen 4 is fixed on the upper part of the screen sliding clamping block 7. The light source 5 is fixed on the upper part of the light source sliding clamping block 8. Because the combined convex lens imaging demonstration instrument is integrally assembled, the utility model has the advantages of compact structure, convenient operation, fast and accurate experimental data reading and favorable visual characteristic. Experiment effects can be effectively raised.

Description

Combined type convex lens image-forming demonstration instrument
Technical field
The utility model relates to a kind of physics teaching convexity lens imaging apparatus for demonstrating, particularly a kind of combined type convex lens image-forming demonstration instrument.
Background technology
At present, in physics teaching, used convex lens image-forming demonstration device comprises that optical bench, convex lens and object and screen constitute, when doing experiment, convex lens are placed on light on the guide rail of seat, vertical respectively object and the screen placed in the both sides of convex lens, the position of mobile object or screen, make present the most clearly image on the screen after, go out object distance and image distance with ruler measurement, utilize experimental data checking imaging formula: 1/f=1/u+1/v.The weak point of this image-forming demonstration device is: used utensil relatively disperses, different convex lens need repeatedly to change, the experimental implementation complexity, waste time and energy, object distance and image distance are also cumbersome with ruler measurement the time, in addition, when using candle to do luminous object, though fairly simple, but operation inconvenience is also unhygienic.
Summary of the invention
The purpose of this utility model is to provide a kind of deficiency that overcomes in the above technology, and structural integrity is good, easy to operate, be convenient to measure, time saving and energy saving, can make several groups of experimental datas, experiment intuitive combined type convex lens image-forming demonstration instrument preferably simultaneously.
For reaching above purpose, the technical scheme that the utility model adopted is: this combined type convex lens image-forming demonstration instrument, by a left side, right support, convex lens sheet, screen, light source constitutes, screen and light source are located at the both sides of convex lens sheet respectively, it is characterized in that on a left side, fixing sliding way between the right support, center fixed epirelief lens turret at slideway, establish screen card and light source card respectively in the both sides of slideway, on the front face of slideway, establish rule, so that can read object distance and image distance intuitively fast, in the corresponding eyeglass that different convex lens sheets is respectively charged into the convex lens turret is trimed, screen is fixed on the top of screen card, and light source is fixed on the top of light source card.The utility model is also implemented by following measure: described convex lens turret, by fixed frame, pole, eyeglass trim, rotation axis constitutes, eyeglass is trimed and is fixed on the upper end of pole by rotation axis, the fixed frame lower end is fixed on the midpoint of slideway, eyeglass is trimed and can be established 3-4, be respectively charged into different convex lens,, can realize that multiple convex lens do lecture experiment simultaneously by the rotation that eyeglass is trimed; Described light source can be the taper bulb, so that differentiate the upper and lower of picture.When using the utility model,, in education experiment, need not to reconfigure, only need the different convex lens sheet of conversion,, read corresponding several groups of image distances and object distance and get final product with the conversion focal length because each unit construction becomes as a whole.
The beneficial effects of the utility model are: compare with the convex lens image-forming demonstration device of present use owing to carried out entire combination, thus compact conformation, easy to operate, experimental data read quick accurate, intuitive is good, can effectively improve experiment effect.
