The back panel is installed at the support; the sliding mechanism is installed at one side of the side surface of the back panel; the luminous source is fixed at the sliding mechanism; the scale plate is installed at the surface of the back panel; and the reflection mechanism is fixed at the support or the back panel and is installed at the same position of the scale plate. The provided teaching instrument has advantages of simple structure, convenient operation, and high practicability; and the teacher can use the instrument easily, thereby realizing teaching easily. Meanwhile, the learning interest of the students can be aroused beneficially; and the students can know and master the physical knowledge easily.
Description
Technical field
The utility model relates to a kind of teaching appliance, especially designs a kind of smooth reflection law demonstrating teaching apparatus.
Background technology
In physics teaching, a lot of laws reflect by bookish linguistic organization and picture, (as: incident ray, reflection ray, incident angle, reflection angle etc.) physics law (reflection law), these definition or law are too abstract for student, cause student's learning interest not high, understand not accurate enough etc. problem, be unfavorable for teaching.
According to practical teaching empirical discovery, use three-dimensional instruments used for education to be easy to obtain classmate's approval and the understanding to knowledge, if there is a kind of instrument that can demonstrate the rule that light reflex time follows, the feature with teaching, inspiration, practicality, can intuitively significantly present and simple to operate being conducive to motivates students' interest in learning by simple light path, be easy to students ' understanding and grasp physical knowledge, but in prior art, having no use or the report of this kind of light reflection law demonstrating teaching apparatus.
Utility model content
The utility model object is to overcome the above-mentioned shortcoming that prior art exists, and provides a kind of simple in structure, easy to operate, has teaching, inspires, is practically applicable to the light reflection law demonstrating teaching apparatus of one.
For achieving the above object, the technological means that the utility model adopts is: a kind of smooth reflection law demonstrating teaching apparatus, comprise support, backboard, light emitting source, slide mechanism, scaleplate, reflecting mechanism, and described backboard is rack-mount; Described slide mechanism is arranged on backboard side on one side, and light emitting source is fixed on slide mechanism; Described scaleplate is arranged on back plate surface; Described reflecting mechanism is fixed on support or backboard, is arranged on scaleplate same position.
Further, described slide mechanism comprises two intermediate plates, in the one side of one of them intermediate plate, is fixed with screw rod, the position perforate of corresponding screw rod on another intermediate plate, utilize nut to realize locking, the intermediate plate another side of standing screw is provided with light source folder, for fixing light emitting source.
Further, described scaleplate is set to semicircle, is provided with angle index line on it.
Further, described reflecting mechanism comprises semicylinder container, is arranged on the reflective mirror on semicylinder container planarea and is filled in the filling liquid in semicylinder container.
Further, described light emitting source adopts laser pen.
The beneficial effects of the utility model are: simple in structure, easy to operate, practical, teacher is upper quick-moving, can realize easily teaching; Be conducive to motivate students' interest in learning simultaneously, be easy to students ' understanding and grasp physical knowledge.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
Fig. 2 is part-structure schematic perspective view of the present utility model.
In figure: 1, support, 2, backboard, 3, light emitting source, 4, slide mechanism, 5, scaleplate, 6, reflecting mechanism, 7, semicylinder container.
Embodiment
A kind of smooth reflection law demonstrating teaching apparatus as shown in Figure 1, comprises support 1, backboard 2, light emitting source 3, slide mechanism 4, scaleplate 5, reflecting mechanism 6, and described backboard 2 is arranged on support 1; Described slide mechanism 4 is arranged on backboard 2 sides on one side, and light emitting source 3 is fixed on slide mechanism 4; Described scaleplate 5 is arranged on backboard 2 surfaces; Described reflecting mechanism 6 is fixed on support 1 or backboard 2, is arranged on scaleplate 5 same positions.
Described slide mechanism 4 comprises two intermediate plates, in the one side of one of them intermediate plate, is fixed with screw rod, and the position perforate of corresponding screw rod on another intermediate plate utilizes nut to realize locking, and the intermediate plate another side of standing screw is provided with light source folder, for fixing light emitting source 3.When reality is used, slide mechanism can adopt various ways, only has the slip of realizing and be standing in a certain position just to can be used as the application's slide mechanism use.
Described scaleplate 5 is set to semicircle, is provided with angle index line on it.Angle index line arranges 0-180 degree.
Described reflecting mechanism 6 comprises semicylinder container 7, is arranged on the reflective mirror 8 on semicylinder container 7 planareas and is filled in the filling liquid in semicylinder container.Filling liquid can be water or other mixed liquors.
Described light emitting source 3 adopts laser pen.The application's support etc. all adopts organic clear glass that 5mm is thick to make.
During use, light source is arranged on slide mechanism, slide mechanism is arranged on the slide rail of demonstrator backboard again, adjusts to a position, the concepts such as understanding reflection of light, incident ray, reflection ray, incident (reflection) point, reflecting surface, normal, incident angle and reflection angle.
Exploratory reflex light and incident ray in same plane, state on Fig. 1, from device left or right side face incident light, reflected light can observe directly them in same plane.
Exploratory reflex light and incident ray, normal relative position, on Fig. 1 basis, slide and change light source incident ray position, from this instrument front, very easily observes directly their relative position relations.
Exploratory reflex angle, with the relation of incident angle, on the basis of previous step, allows incident angle increase gradually (or reducing), reads simultaneously, records corresponding incident angle and the reflection angle number of degrees can be found out.
Vertical reflection during vertical incidence, it is zero state that slide mechanism is slided into incident angle, from positive side, all can directly see this phenomenon.
The structure of the design embodiment; be only embodiment of the present utility model, be not limited to this, be anyly familiar with those skilled in the art in the technical scope that the utility model discloses; can expect easily changing or replacing, within all should being encompassed in protection domain of the present utility model.
