Abstract
The utility model relates to a physics teaching experiment demonstration device, and especially relates to an eyeball imaging simulating device. The eyeball imaging simulating device comprises a pedestal (1), a scrip (2), a glass ball (3), a magnifier (4), a card clamp (5) and an electric torch (6), and is characterized in that the glass ball (3), the magnifier (4), the card clamp (5) and the electric torch (6) are respectively disposed on the pedestal (1) and located on the same axis; the glass ball (3) is especially of a hollow thin wall structure, an external surface of one side of the glass ball (3) is fixedly provided with the scrip (2), and the other side of the glass ball (3) is provided with the magnifier (4); the card clamp (5) is positioned between the magnifier (4) and the electric torch (6); and the magnifier (4) is slidably connected with the pedestal (1).
Description
Technical field
The utility model relates to a kind of physics teaching experiment apparatus for demonstrating, specifically a kind of ocular imaging analogue means.
Background technology
Physics is one and take natural science as basic subject, and a lot of spontaneous phenomenons will go to explain by physical knowledge, so should first learn rudimentary knowledge well, are that student should possess in study.By a large amount of experiments, allow student go the ability of analysis and solve problem, yet knowledge and ability is the two large key elements that form modern talent.Knowledge is the basis of ability, and be converted into ability under certain condition, and be not that all knowledge is all converted into ability, only have knowledge alive just to have the ability to be worth, so only a lot of theories are proved in reliable experiment, the effect of giving full play to, bring into play student's space imagining ability and innovation ability simultaneously, courageously remove to wave rope, dare to ask a question, problem analysis, finally deals with problems.
By the situation and teacher is when doing lecture experiment in classroom at ordinary times in experiment of student in recent years, some problems that student proposes combine, and cause each student to grasp related content and technology.At present, the experimental demonstration device using is mainly the physical knowledge that needs emphasis to grasp in teaching programme for belonging in physics textbook, for some simple Physical Experiments after class, teacher is just slided over, can not get paying attention to, cannot be that student grasps comprehensively and understands knowledge point, cause physics student study to occur blind spot, reduce learning efficiency and learning interest.
Summary of the invention
For the problems referred to above, the utility model provides a kind of ocular imaging analogue means, solve existing Physical Experiment apparatus for demonstrating and cannot meet the demonstration of simple Physical Experiment after class, caused physics student study to occur blind spot, reduced the problem of learning efficiency and learning interest.
For achieving the above object, the technical solution of the utility model is specific as follows:
An ocular imaging analogue means, comprises base 1, the scraps of paper 2, glass bead 3, magnifier 4, card holder 5, electric torch 6; It is characterized in that: glass bead 3, magnifier 4, card holder 5, electric torch 6 are set respectively on described base 1, described glass bead 3, magnifier 4, card holder 5, electric torch 6 are on same axis, wherein said glass bead 3 is specially hollow thin-wall structure, one side external surface is fixedly installed the scraps of paper 2, the opposite side of glass bead 3 arranges magnifier 4, the centre position of card holder 5 in magnifier 4 and electric torch 6.
An ocular imaging analogue means wherein, described magnifier 4 is slidably connected with base 1.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, easy to operate, improved the efficiency of Students ' Learning, improved teacher's the efficiency of giving lessons, solve existing Physical Experiment apparatus for demonstrating and cannot meet the demonstration of simple Physical Experiment after class, caused physics student study to occur blind spot, reduced the problem of learning efficiency and learning interest; Make the abstract sight that straightens, reduced the knowledge difficulty on teaching material, student is understood easily, with deep impression, improved student's observation ability and thinking ability, Physics Learning is turned easily by difficulty, be full of interest, practical reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model card holder 5 is put into the structural representation after card.
Wherein, 1. base, the 2. scraps of paper, 3. glass bead, 4. magnifier, 5. card holder, 6. electric torch.
Embodiment
Below in conjunction with specification drawings and specific embodiments, the utility model is further described:
An ocular imaging analogue means, comprises base 1, the scraps of paper 2, glass bead 3, magnifier 4, card holder 5, electric torch 6; It is characterized in that: glass bead 3, magnifier 4, card holder 5, electric torch 6 are set respectively on described base 1, described glass bead 3, magnifier 4, card holder 5, electric torch 6 are on same axis, wherein said glass bead 3 is specially hollow thin-wall structure, one side external surface is fixedly installed the scraps of paper 2, the opposite side of glass bead 3 arranges magnifier 4, the centre position of card holder 5 in magnifier 4 and electric torch 6.
An ocular imaging analogue means wherein, described magnifier 4 is slidably connected with base 1.
The utility model in use, electric torch 6 is opened, figure on card holder 5 will be incident upon on the scraps of paper 2 of glass bead 3 one sides, an inverted image that just there will be figure on card holder 5 on the scraps of paper 2, magnifier 4 moves around, until image is clear, the black hole in the middle of eyes is exactly pupil, and light enters the crystalline lens in eyes by pupil.When light is weak, pupil can amplify, and allows more light come in; When light is strong, pupil can dwindle.
The utility model is simple in structure, easy to use, easy to operate, improved the efficiency of Students ' Learning, improved teacher's the efficiency of giving lessons, solve existing Physical Experiment apparatus for demonstrating and cannot meet the demonstration of simple Physical Experiment after class, caused physics student study to occur blind spot, reduced the problem of learning efficiency and learning interest; Make the abstract sight that straightens, reduced the knowledge difficulty on teaching material, student is understood easily, with deep impression, improved student's observation ability and thinking ability, Physics Learning is turned easily by difficulty, be full of interest, practical reliable.
Claims (2)
1. an ocular imaging analogue means, comprises base (1), the scraps of paper (2), glass bead (3), magnifier (4), card holder (5), electric torch (6); It is characterized in that: glass bead (3), magnifier (4), card holder (5), electric torch (6) are set respectively on described base (1), described glass bead (3), magnifier (4), card holder (5), electric torch (6) are on same axis, wherein said glass bead (3) is specially hollow thin-wall structure, one side external surface is fixedly installed the scraps of paper (2), the opposite side of glass bead (3) arranges magnifier (4), the centre position of card holder (5) in magnifier (4) and electric torch (6).
