Abstract
The utility model relates to a kind of eyeball light refraction demonstrating model, described demonstrating model is by light beam generator, transparent refractive plate and chart board, described light beam generator has the luminescence unit of three or more odd numbers, described luminescence unit spaced set, and sends the covering of the fan light be parallel to each other; Described transparent refractive plate shape is oval.The utility model sends multiple covering of the fan light be parallel to each other by multiple luminescence units of described light beam generator, described chart board is printed with the cut-open view of the different situation eyes such as normal, near-sighted and long sight, transparent refractive plate is placed in the lenticular position of eyes cut-open view, covering of the fan light is incident upon on chart board after the refraction of described transparent refractive plate, the cut-open view of eyeball can be seen the convergent point of many light, observe the different situations such as convergent point can represent normally respectively from the relative position between eye ground, near-sighted and long sight.
Description
Technical field
The utility model relates to a kind of classroom instruction instrument, is specifically related to a kind of eyeball light refraction demonstrating model.
Background technology
At present in medical teaching, for the relation of eyes in eyeball to the refraction of light and the effect of focusing and eye eyesight, a not good demonstration teaching aid, usually can only illustrate with chalk on-the-spot drawing on blackboard, both time-consuming, be difficult to again accurate expression, affect teaching efficiency.
Summary of the invention
The purpose of this utility model is the deficiency existed for prior art, provide a kind of not only image, accurately, but also eyeball light refraction demonstrating model easy to use.
For achieving the above object, the utility model provides following technical scheme: a kind of eyeball light refraction demonstrating model, it is characterized in that: described demonstrating model is by light beam generator, transparent refractive plate and chart board, described light beam generator has the luminescence unit of three or more odd numbers, described luminescence unit spaced set, and send the covering of the fan light be parallel to each other; Described transparent refractive plate shape is oval.
The utility model sends multiple covering of the fan light be parallel to each other by multiple luminescence units of described light beam generator, described chart board is printed with the cut-open view of the different situation eyes such as normal, near-sighted and long sight, transparent refractive plate is placed in the lenticular position of eyeball cut-open view, covering of the fan light is incident upon on chart board after the refraction of described transparent refractive plate, the cut-open view of eyes can be seen the convergent point of many light, observe the different situations such as convergent point can represent normally respectively from the relative position between eye ground, near-sighted and long sight.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Accompanying drawing explanation
Fig. 1 is the utility model light beam generator specific embodiment structural representation;
Fig. 2 is the utility model transparent refractive plate specific embodiment structural representation;
Fig. 3 is the utility model chart board specific embodiment structural representation;
Fig. 4 is the utility model using state schematic diagram.
Embodiment
As Figure 1-3, eyeball light refraction demonstrating model is made up of light beam generator 1, transparent refractive plate 2 and chart board 3 three part.Described light beam generator 1 has the luminescence unit 101 of three or more odd numbers, is advisable with 3-7, described luminescence unit 101 spaced set, and sends the covering of the fan light be parallel to each other; Arranging the object of odd number luminescence unit 101, is in order to when demonstrating, and the light sent using middle luminescence unit 101 is as optical axis, and remaining is symmetrical to Themiddle refractive, more vivid from both sides.As shown in Figure 1, three luminescence units 101 are set in this specific embodiment, described three luminescence unit 101 spaced sets, described three luminescence units 101 are arranged in a plastic casing 102, luminescence unit 101 is made up of the laser generator in commercially available laser pen, and plastic casing 102 is provided with three switches 103 on the surface and controls described three luminescence units 101 respectively.As shown in Figure 2, described transparent refractive plate 2 shape is oval, and shape is similar to crystalline lens cross section, and the transparent organic plates that can be specifically 4-10mm by thickness is made.Described chart board 3 can be made up of cardboard or plastic plate, as shown in Figure 3, described chart board 3 is printed with the cut-open view of the different situation eyeballs such as normal, myopia and long sight respectively, conveniently uses, can also go out at marked thereon the position mark that transparent organic plates and light beam generator put.
As shown in Figure 4, during use, transparent refractive plate 2 is placed in the lenticular position of eyeball cut-open view on described chart board 3, open three switches 103 of three luminescence units 101, covering of the fan light is incident upon on chart board after the refraction of described transparent refractive plate 2, the cut-open view of eyeball can be seen the convergent point of many light, observe the different situations such as convergent point can represent normally respectively from the relative position between eye ground, near-sighted and long sight.
Claims (3)
