Abstract
The invention provides a visual imaging demonstration instrument. The visual imaging demonstration instrument comprises a lens, a mobile optical screen and a shell, wherein the lens and the mobile optical screen are arranged in the shell; an imaging hole is formed in one side surface of the shell; the imaging hole, the lens and the mobile optical screen are sequentially arranged in a straight line. The visual imaging demonstration instrument is simple in structure, convenient to manufacture and low in cost.
Description
Technical field
The present invention relates to a kind of visual imaging demonstrator.
Background technology
At study vision forming process comparatively indigestion, if drawing to teach by teacher merely needs student to have higher imagination, this causes partial students to understand, and its equipment is relatively backward in some schools, school cannot provide funds to buy corresponding equipment, therefore designs and produces the process that a kind of visual image demonstrator help student understands vision formation.
Summary of the invention
The technical problem to be solved in the present invention, is to provide a kind of visual imaging demonstrator, and structure is simple, easy to make, with low cost.
The present invention is achieved in that a kind of visual imaging demonstrator, comprise lens, mobile optical screen and shell, described lens and mobile optical screen are located in described shell, and described shell one side is provided with an imaging hole, and described imaging hole, lens and mobile optical screen are arranged in a line successively.
Further, also comprise a conduit and a compressor reducer, be full of transparency liquid in described lens, described compressor reducer passes through the end of described tubes connection to described lens.
Further, described lens comprise a plastic tube and two pieces of elastic films, and described plastic tube is interconnected end to end, and described two pieces of elastic films are located at the lens that described plastic tube both sides form sealing respectively, and described plastic tube is connected to described conduit.
Further, described compressor reducer is a syringe.
Further, described transparency liquid is pure water.
Further, described shell is printing opacity, and described shell is provided with a sightingpiston.
Tool of the present invention has the following advantages: visual imaging demonstrator of the present invention, can embody the change in the process of visual imaging and visual imaging process very intuitively, is convenient to student and understands; And it is easily manufactured, with low cost.
Accompanying drawing explanation
The present invention is further illustrated in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the structural representation of visual imaging demonstrator of the present invention.
Fig. 2 is lens schematic diagram one of the present invention.
Fig. 3 is lens schematic diagram two of the present invention.
Embodiment
As shown in Figure 1 to Figure 3, visual imaging demonstrator, comprise lens 1, mobile optical screen 2, shell 3, one conduit 4 and a compressor reducer 5, described lens 1 and mobile optical screen 2 are located in described shell 3, described shell 3 one side is provided with an imaging hole 31, described imaging hole 31, lens 1 and mobile optical screen 2 are arranged in a line successively, transparency liquid 13 is full of in described lens 1, described compressor reducer 5 is connected to an end of described lens 1 by described conduit 4, described shell 3 is printing opacity, and described shell 3 is provided with a sightingpiston 32, namely this shell 3 is rectangle, and shell 3 is removed in two faces above, form sightingpiston 32.
As shown in Figures 2 and 3, in the present invention, lens 1 comprise a plastic tube 11 and two pieces of elastic films 12, described plastic tube 11 is interconnected end to end, form an airtight ring, described two pieces of elastic films 12 are located at the lens (i.e. the both sides of two pieces of elastic film 12 abutment rings) that described plastic tube 11 both sides form sealing respectively, described plastic tube 11 is connected to described conduit 4, described compressor reducer 5 is a syringe, described transparency liquid 13 is pure water, by syringe being carried out the change compressing or decontrol the elastic film 12 that can make in lens 1, thus regulate the focal length of lens 1, wherein plastic tube 11 is PVC plastic pipe, also be full of transparency liquid 13 in plastic tube 11 and compressor reducer 5.
As shown in Figure 1 to Figure 3, one candle 6 is placed in the outside of the imaging hole 31 of described shell 3, then by regulating compressor reducer 5 lens 1 can be focused, until form the reality of a candle handstand on mobile optical screen 2, if all cannot move on optical screen 2 in the process regulating compressor reducer 5 is formed with reality again, then can be realized the formation of reality by mobile optical screen 2.
Tool of the present invention has the following advantages: visual imaging demonstrator of the present invention, can embody the change in the process of visual imaging and visual imaging process very intuitively, is convenient to student and understands; And it is easily manufactured, with low cost.
Although the foregoing describe the specific embodiment of the present invention; but be familiar with those skilled in the art to be to be understood that; specific embodiment described by us is illustrative; instead of for the restriction to scope of the present invention; those of ordinary skill in the art, in the modification of the equivalence done according to spirit of the present invention and change, should be encompassed in scope that claim of the present invention protects.
