Abstract
An educational apparatus of flat mirror imaging demonstration or manipulation comprises a grid coordinate platform, supporting stands with slots, a semi-transparent flat mirror and supporting shoes, wherein each end of a zero coordinate line of the grid coordinate platform is provided with the supporting stand with slot, the flat mirror is inserted into the slots of the supporting stands to cause the zero coordinate line and mirror surface to be in the same plane surface, the mirror surface is vertical to the grid coordinate platform, and the two ends of some side of the grid coordinate platform are respectively provided with a supporting shoe, when the supporting shoes is raised, the platform is propped up in a certain angle, when the supporting shoes are folded, the platform is laid horizontally. When being used, an object being observed is put at some coordinate before the flat mirror, and the image of the object can be observed through the flat mirror, another object with the same shape and size as the object being observed is caused to move on the imaging side of the platform until the object is completely superposed with the object being observed, and then the features of flat mirror imaging can be directly and accurately obtained according to the coordinates where the two objects are located.
Description
Affiliated technical field
The utility model relates to the instruments used for education of a kind of mirror imaging demonstration or operation.
Background technology
At present, " mirror imaging " experiment of in physical textbook, arranging, be to spread a big blank sheet of paper on the table, erect a simple glass plate on the paper, as level crossing, the observation object is done in the front that a candle of lighting is placed on glass plate, taking a same candle of not lighting to be placed on the glass plate back again goes to overlap fully with the picture of that candle of front, position with bundle of lines candle and its picture is linked up, measure their distances with rule, just can draw the characteristics of mirror imaging to level crossing.This cover experimental provision all needs line at every turn when practical operation, also will measure with rule, not only bothers but also lose time, and all can have error when measuring at every turn.The level crossing that simple glass is done, because transmittance is very strong, imaging is unintelligible, not obvious, the observation difficulty is bigger.Therefore, concerning people, also lack a kind of above-mentioned shortcoming that overcomes, can demonstrate instruments used for education directly perceived, quick, convenient, clear, exactly with the imaging of operation planar mirror.
Summary of the invention
In order to overcome existing deficiency, the utility model provides a kind of energy directly perceived, quick, convenient, clear, the instruments used for education of demonstration and the imaging of operation planar mirror exactly.
The technical scheme that its technical matters that solves the utility model adopts is: it is by the platform that mesh coordinate is arranged, the support of band slot, and semi-transparent level crossing, leg is formed.It is the support that a band slot respectively is set at the two ends of the zero coordinate line of mesh coordinate platform, level crossing is inserted in the slot of support, make zero coordinate line and minute surface on same plane, minute surface is vertical with the mesh coordinate platform, on the both sides of mesh coordinate platform side a leg is arranged respectively, erect leg, prop the platform inclination certain angle, leg is packed up, and makes the platform horizontal positioned.During use, observed object is placed on the preceding a certain coordinate place of level crossing, can be observed its picture by level crossing, with another and observing object shape and equirotal object, on the platform of imaging one side, move, overlap fully with the picture of observed object up to this object,, can draw the characteristics of mirror imaging directly, exactly according to the coordinate at two object places.Can also be cut into chromo board and grid two lattice equal and opposite in directions, and post double faced adhesive tape overleaf, can be bonded at certain coordinate place of coordinates platform, allow observation of students picture of cardboard in level crossing occupy the lattice number identical, can judge the equal and opposite in direction that looks like with object directly, exactly with cardboard.
The beneficial effects of the utility model are: this instrument is simple, intuitive and workable, be subjected to the influence of artificial labile factor little, real result, utilization has the platform of coordinate to replace blank sheet of paper, not only can simplify the operation course, more can draw the characteristics of mirror imaging intuitively, fast, easily and accurately.Replace simple glass with semi-transparent level crossing, strengthened the considerable degree of image, can accomplish overlapping of thing and picture during operation clear, accurately.Leg can allow the platform inclination certain angle, increases student's considerable degree when being convenient to demonstrate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model mirror imaging teaching appliance.
(1) semi-transparent level crossing among the figure, (2) mesh coordinate platform, (3) support, (4) leg.
Embodiment
In accompanying drawing 1, respectively be provided with the support (3) of band slot at the zero coordinate line two ends of mesh coordinate platform (2), semi-transparent level crossing (1) is inserted in the slot of support (3), the minute surface that makes mesh coordinate platform (2) zero coordinate line and semi-transparent level crossing (1) is on same plane, the minute surface of semi-transparent level crossing (1) is vertical with the plane at mesh coordinate platform (2) place, on the both sides of the mesh coordinate platform (2) of a side of semi-transparent level crossing (1) leg (4) is set respectively.During use, observed object, be placed on a certain coordinate place of the mesh coordinate platform (2) of semi-transparent level crossing (1) front, can be observed its imaging by semi-transparent level crossing (1), then another and observing object shape and equirotal object are gone up at the mesh coordinate platform (2) of a side of imaging and moved, overlap fully with observed object imaging up to this object, according to the coordinate figure of two objects on mesh coordinate platform (2), can be directly perceived, fast, draw mirror imaging exactly, have object distance and equate, thing and the line of the picture characteristics vertical with the level crossing minute surface with image distance.Can also be cut into chromo board and grid two lattice equal and opposite in directions, and post double faced adhesive tape overleaf, be bonded at certain coordinate place of mesh coordinate platform (2) and allow observation of students cardboard imaging occupy and cardboard apposition number mutually, can judge the equal and opposite in direction of picture and object exactly.Can erect both sides leg (4) this moment, makes the platform inclination certain angle, makes things convenient for observation of students.
Claims (1)
1. mirror imaging teaching appliance, it is by the platform that mesh coordinate is arranged, the support of band slot, semi-transparent level crossing, leg is formed, it is characterized in that: the zero coordinate line of mesh coordinate platform is provided with semi-transparent level crossing, the two ends of level crossing respectively are provided with the support of a band slot, be used for fixing semi-transparent level crossing, the minute surface that makes zero coordinate line and semi-transparent level crossing is on same plane, and the minute surface of semi-transparent level crossing is vertical with the plane at mesh coordinate platform place, on the both sides of mesh coordinate platform side a leg is set respectively, erect leg, can prop the platform inclination certain angle.
