Abstract
The utility model discloses a plane mirror imaging principle display instrument, belonging to the physics teaching experimental apparatus field. The structure of the plane mirror imaging principle display instrument comprises a plane mirror, a mirror holder and a rotating shaft, wherein two mirror holders freely rotating about the rotating shaft are arranged on the rotating shaft; plane mirrors with mirror surfaces facing each other are locked in the mirror holder; an angle scale is arranged at the bottom of the rotating shaft; and angle lines are formed on the angle scale. The plane mirror imaging principle display instrument provided in the utility model, compared with the prior art, is rational in design, simple in structure, easy for processing, convenient for demonstration, and the like; therefore, the study train of thought of students is effectively expanded, the study interests of the students are enhanced and the study quality is improved.
Description
Technical field
The utility model relates to the physics teaching experiment instrument field, specifically mirror imaging principle demonstration instrument.
Background technology
The mirror imaging principle is the joint important content during junior physics is learned.When this image-forming principle of demonstration; Teacher's experimental apparatus generally is exactly a level crossing, and this makes the student in learning process, when being difficult between the mirror of the imagination two sides angle variation take place; To the variation of object image-forming, this big limitations the understanding of student to the mirror imaging principle.
Summary of the invention
The technical assignment of the utility model is to above weak point, provide a kind of simple in structure, demonstrate mirror imaging principle demonstration instrument easily.
The utility model solves the technical scheme that its technical matters adopted: this mirror imaging principle demonstration instrument comprises level crossing, mirror holder and rotating shaft; Rotating shaft is provided with two mirror holders that can freely rotate around the shaft, and card has the corresponding each other level crossing of minute surface in the mirror holder; The bottom of rotating shaft is provided with angle scale, and angle scale is provided with angle line.
Described rotating shaft is arranged on the home position of angle scale.
The mirror imaging principle demonstration instrument of the utility model is compared with prior art; Have reasonable in design, simple in structure, be easy to characteristics such as processing, demonstration is convenient; Effectively expand the Students'learning thinking, strengthened students'interest in learning, improved learning quality.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Accompanying drawing is the structural representation of mirror imaging principle demonstration instrument.
Among the figure: 1, level crossing, 2, mirror holder, 3, rotating shaft, 4, angle scale, 5, angle line.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
The mirror imaging principle demonstration instrument of the utility model, its structure comprises level crossing 1, mirror holder 2 and rotating shaft 3, rotating shaft 3 be provided with two can be around the shaft 3 mirror holders 2 that freely rotate, card has the corresponding each other level crossings 1 of minute surface in the mirror holder 2; The bottom of rotating shaft 3 is provided with angle scale 4, and angle scale 4 is provided with angle line 5, and rotating shaft 3 is arranged on the home position of angle scale 4.
When doing experimental demonstration, between two level crossings 1, be placed to the picture article,, make that angle changes between two level crossings 1, thereby the variation of article imaging occurs through rotating two level crossings 1.
Its processing and fabricating of mirror imaging principle demonstration instrument of the utility model is very simple and convenient, and processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
