Abstract
A kind of simulated eyeballs experimental provision, it comprises a base, an organic glass ball cover is fixed with above described base, the rear and front end opening of this organic glass ball cover, cover at open rearward end place and thin paper film is housed, simulation retina, the transparent balloon that one is equipped with water is installed at front opening place, simulation crystalline lens, be provided with the leather hose communicated with transparent balloon interior at the tying place of transparent balloon, the other end of leather hose is provided with syringe, can be changed the thickness of transparent balloon by push-and-pull syringe, be provided with light source in the front side of transparent balloon, this light source can imaging on thin paper film.The outer wall of described transparent balloon and the surrounding at organic glass ball cover front opening place are fixed by glue.The utility model can help student to understand the structure of eyes, and crystalline lens and amphiblestroid effect, have the advantage that structure is simple, easy to operate, can make a profound impression to student.
Description
Technical field
The utility model relates to a kind of simulated eyeballs device for testing, specifically a kind of simulated eyeballs experimental provision that can regulate lens thickness.
Background technology
What kind of do are the structure of eyes? do are eyes how imagings? does crystalline lens have anything to act on? these acquire in middle school's text, but teacher simply explains facing to picture, student is difficult to deep cognition, need some experimental provision aided educations for this reason, student just can be made to have deep understanding to eyes.Patent Office of the People's Republic of China is disclosed in 3 days September in 2014, and the patent No. is a kind of ocular imaging analogue means of " 201420101859.7 ", comprises base, the scraps of paper, glass bead, magnifier, card holder, electric torch; It is characterized in that: described base arranges glass bead, magnifier, card holder, electric torch respectively, described glass bead, magnifier, card holder, electric torch are on same axis, wherein said glass bead is specially hollow thin-wall structure, one side external surface is fixedly installed the scraps of paper, the opposite side of glass bead arranges magnifier, card holder is in the centre position of magnifier and electric torch, and described magnifier is connected with base sliding.This ocular imaging analogue means utilizes magnifier to simulate crystalline lens inherently a kind of misleading to student, and changing because crystalline lens is thickness, is not displacement.
Summary of the invention
The purpose of this utility model is defect for above-mentioned prior art and deficiency, for people provide a kind of simulated eyeballs experimental provision that can regulate lens thickness, goes back aided education.
For achieving the above object, technical solution adopted in the utility model is: this simulated eyeballs experimental provision, it comprises a base, an organic glass ball cover is fixed with above described base, the rear and front end opening of this organic glass ball cover, cover at open rearward end place and thin paper film is housed, simulation retina, the transparent balloon that one is equipped with water is installed at front opening place, simulation crystalline lens, the leather hose communicated with transparent balloon interior is provided with at the tying place of transparent balloon, the other end of leather hose is provided with syringe, the thickness of transparent balloon can be changed by push-and-pull syringe, light source is provided with in the front side of transparent balloon, this light source can imaging on thin paper film.
The outer wall of described transparent balloon and the surrounding at organic glass ball cover front opening place are fixed by glue.
Described light source is candle or LED composition.。
Described base is provided with slide rail, and slide rail is movably installed with a slide block, and described light source is placed on slide block.
The utility model transparent balloon that water is housed, simulation crystalline lens, with thin paper membrane simulation retina, can help student to understand the structure of eyes.Different according to the distance of light source, being regulated the thickness of transparent balloon by push-and-pull syringe, make thin paper film place obtain the picture of light source clearly, making student can understand the lenticular change when seeing near objects and distant objects.Can also find that the imaging of light source is stood upside down by thin paper film, thus cognition imaging on the retina is also stand upside down.There is the advantage that structure is simple, easy to operate, can make a profound impression to student.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of simulated eyeballs experimental provision, and it comprises a base, is fixed with an organic glass ball cover 2 above described base 9, the rear and front end opening of this organic glass ball cover 2.Cover at open rearward end place and thin paper film 1 is housed, simulation retina, is provided with the transparent balloon 3 that is equipped with water at front opening place, simulation crystalline lens.The outer wall of described transparent balloon 3 and the surrounding at organic glass ball cover 2 front opening place are fixed by glue.Be provided with the leather hose 4 communicated with transparent balloon 3 inside at the tying place of transparent balloon 3, the other end of leather hose 4 is provided with syringe 6, can be changed the thickness of transparent balloon 3, be similar to the change of lens thickness by push-and-pull syringe 6.Be provided with light source 5 in the front side of transparent balloon 3, this light source 5 can imaging on thin paper film 1, can obtain in the thickness change process of transparent balloon 3 one clearly as.Described light source 5 is candle or LED, and LED can be combined into sagittate array, more easily find the handstand that is imaged as on thin paper film 1, thus cognition imaging on the retina is also stand upside down.Described base 9 is provided with slide rail 8, and slide rail 8 is movably installed with a slide block 7, and described light source 5 is placed on slide block 7, can regulate the distance between light source 5 and transparent balloon 3 by moving slider 7.Light source 5 away from time, need with syringe extraction section water could obtain clearly as, when light source 5 shifts near, promote syringe 6 to the water filling of transparent balloon 3 could obtain clearly as, therefore can know that we are when seeing distant objects, ciliary muscle can pull crystalline lens, make crystalline lens thinning, when seeing near objects, ciliary muscles relax, crystalline lens shrinks, and makes crystalline lens thickening.
The utility model transparent balloon 3 that water is housed, simulation crystalline lens, simulates retina with thin paper film 1, student can be helped to understand the structure of eyes.Different according to the distance of light source 5, being regulated the thickness of transparent balloon 3 by push-and-pull syringe 6, make thin paper film 1 place obtain the picture of light source 5 clearly, making student can understand the lenticular change when seeing near objects and distant objects.By thin paper film 1 can also find light source 5 similarly be stand upside down, thus cognition on the retina picture be also stand upside down.There is the advantage that structure is simple, easy to operate, can make a profound impression to student.
