Abstract
The utility model discloses a demonstration device for eye imaging, comprising a double axis slide-rail, a slide block, a candle, a sphere transparent plastic board, a rubber ring, a transparent rubber bag, a transparent plastic piston, a rubber tube and a light screen. The slide block is able to slide on the double axis slide rail, and the candle, the sphere transparent plastic board, the transparent rubber bag and the light screen are fixed on the slide block and the transparent rubber is connectd with the transparent plastic piston through the rubber tube, and the rubber is fixed at the transparent rubber bag; water is filled into the transparent rubber bag or the transparent plastic piston. Since the transparent elastic rubber bag is used to hole water, the piston is used to fill and extract water into the rubber bag through the rubber tube and two sides of the rubber bag turns thin and thick, while the demonstrated eye will also turn thin and thick when observing near or remote object; the two sphere transparent plastic boards are used to squeeze the rubber bag holding water to constitute a concave mirror and convex with different focus to replace eyeglass for demonstration rectification of myopia and presbyopia.
Description
Technical field
The utility model relates to a kind of biology and physics teaching class demonstration device, particularly a kind of eyes imaging teaching demonstration device that relates to eyes imaging and myopia and the farsightedness origin cause of formation and rectification.
Background technology
When telling about the eyes imaging in biology and the physics teaching now, there is the eyeball phantom structure to introduce the structure of eyeball and specifically imaging, use candle flame during the demonstration imaging, convex lens and optical screen replace the object of looking respectively, crystalline lens and retina, the variation of crystalline lens thickness shape and the variation of focal length when watching thing far away and nearly thing, be to realize with the convex lens that change different focal, because eye retina and crystalline lens distance are fixed, constant as if keeping convex lens and optical screen distance when experiment, changing the convex lens after image is difficult to clearly become on optical screen, picture is clearly become on optical screen, then need change convex lens and optical screen distance, this does not conform to the practical structures of eyes.Demonstration myopia and farsightedness lens shapes change when causing focal length variations, also the convex lens that can only use different focal instead are realized, lens shapes changes and can't demonstrate, and demonstration can not accurately become picture on retina during with farsightedness with the convex lens correction of myopia with concavees lens.
Summary of the invention
The purpose of this utility model is exactly the eyes imaging teaching demonstration device that a kind of convenient demonstration eyes imaging and myopia and the farsightedness origin cause of formation and rectification will be provided.
The purpose of this utility model is achieved in that a kind of eyes imaging teaching demonstration device, comprise twin shaft slide rail 1, slide block 2, candle flame 3, sphere thin transparent plastic plate 4 and 9, rubber retainer plate 6 and 11, transparent rubber bag 5 and 10, transparent plastic piston 8 and 13, rubber tube 7 and 12 and optical screen 14, slide block 2 can slide on twin shaft slide rail 1, candle flame 3, sphere thin transparent plastic plate 4 and 9, transparent rubber bag 5 and 10 and optical screen 14 be fixed on the slide block 2, transparent rubber bag 5 links to each other with 13 with transparent plastic piston 8 with 12 by rubber tube 7 with 10, rubber retainer plate 6 and 11 is fixed on transparent rubber bag 5 and 10, transparent rubber bag 5 and 10 and transparent plastic piston 8 and 13 in annotate clear water.
The utility model is owing to adopt Sheng clear water in the transparent elastic rubber bag, with piston by rubber tube water filling and drawing water in rubber bag, make rubber bag left and right sides two sides thickening and attenuation, crystalline lens thickening and attenuation when being used to demonstrate eyes and watching nearly thing and thing far away, adopt two sphere transparent plastic sheets extruding dress water rubber bag again, can form concavees lens and the convex lens that focal length varies in size and demonstrate myopia and presbyopic rectification with replacement spectacles and spectacles for long sight.The utility model also is simple in structure and convenient in use.
Description of drawings
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 1 double as Figure of abstract.
Embodiment
As shown in Figure 1, a kind of eyes imaging teaching demonstration device, comprise twin shaft slide rail 1, slide block 2, candle flame 3, sphere thin transparent plastic plate 4 and 9, rubber retainer plate 6 and 11, transparent rubber bag 5 and 10, transparent plastic piston 8 and 13, rubber tube 7 and 12 and optical screen 14, slide block 2 can slide on twin shaft slide rail 1, candle flame 3, sphere thin transparent plastic plate 4 and 9, transparent rubber bag 5 and 10 and optical screen 14 be fixed on the slide block 2, transparent rubber bag 5 links to each other with 13 with transparent plastic piston 8 with 12 by rubber tube 7 with 10, rubber retainer plate 6 and 11 is fixed on transparent rubber bag 5 and 10, transparent rubber bag 5 and 10 and transparent plastic piston 8 and 13 in annotate clear water.
When the demonstration eyes are observed object, use candle flame 3, rubber bag 10, piston 13 and optical screen 14, rubber bag 10 is represented eye lens, and optical screen 14 is represented retina, and candle flame 3 is represented the object of looking, and keeps rubber bag 10 and optical screen 14 distances constant.When candle flame 3 away from or represent to watch thing far away and nearly thing when the rubber bag 10, with drawing water or water filling in 13 pairs of rubber bag 10 of piston, rubber bag 10 left and right thickness thickening or attenuation, expression crystalline lens thickening or attenuation, the picture of candle flame 3 can clearly be on optical screen 14, and the expression object picture of looking becomes on retina.
When demonstration farsightedness and the myopia origin cause of formation, at first use candle flame 3, rubber bag 10, piston 13 and optical screen 14, move candle flame 3 make its can on optical screen 14, become clearly as, expression normal eye observation object image-forming situation keeps above position of components constant.Draw water or water filling with 13 pairs of rubber bag 10 of piston, this moment rubber bag 10 left and right thickness attenuation or thickenings, represent eye lens attenuation or thickening and become farsightedness or myopia, 3 pictures of the candle flame on the optical screen 14 fog at this moment, and the picture of expression object can not become on retina.
When demonstration farsightedness and myopia are corrected, keep said elements position and state constant, increase and use rubber bag 5, piston 8, sphere transparent plastic sheet 4 and 9, when farsightedness or myopia were corrected in demonstration, the relative rubber bag 5 of pushing with 9 liang of concave surfaces or convex surface of plastic plate 4 made it become water quality convex lens or water quality concavees lens, and regulate with piston 8 how many water change its thickness and focal length in the rubber bag 5, make candle flame 3 pictures again clear one-tenth on optical screen 14.
Apparatus of the present invention are simple in structure, and material is easy to get, and are easy to make, and apparatus of the present invention also can be used as demonstration lens characteristics, show the image-forming principle of devices such as emblem mirror, telescope.
