Abstract
The utility model relates to a teaching product, in particular to an anti-reflecting blackboard, which consists of a main panel, a right panel and a left panel, wherein the right panel is positioned on the right of the main panel and is rotationally connected with the main panel through a right rotating shaft; the left panel is positioned on the left of the main panel and is rotationally connected with the main panel through a left rotating shaft; the right rotating shaft and the left rotating shaft are connected with a motor; the main panel is provided with a right panel angle adjusting button and a left panel angle adjusting button; and the motor is controlled to start or stop and steer by the right panel angle adjusting button and the left panel angle adjusting button. The anti-reflecting blackboard overcomes a defect that students hardly recognize contents on the blackboard when the traditional blackboard reflects light intensively, and has certain advantages.
Description
Technical field
The utility model relates to a kind of realia, especially a kind of reflection prevention blackboard.
Background technology
Blackboard is a realia indispensable in the school instruction process; But present blackboard is the plane mostly; Certain time period in one day is prone to take place reflective strong phenomenon; So some students particularly are sitting in the content of writing on the difficult resolution of the student blackboard on both sides, classroom, have caused some troubles to students.
The utility model content
The utility model is intended to address the above problem, and a kind of reflection prevention blackboard is provided, and it has overcome the difficult drawback of differentiating the content on the blackboard of student when using traditional blackboard reflective light strong, and its technical scheme that adopts is following:
A kind of reflection prevention blackboard; Form by main panel, right panel and left panel; Said right panel is positioned at the main panel right side and is rotationally connected through right-hand rotation moving axis and main panel; Said left panel is positioned at that main panel passes on left the left-hand rotation moving axis and main panel is rotationally connected; Said right-hand rotation moving axis is connected with motor with the left-hand rotation moving axis, and said main panel is provided with right panel angular adjustment button and left panel angular adjustment button, the break-make of said motor with turn to by right panel angular adjustment button and the button control of left panel angular adjustment.
The utlity model has following advantage: simple in structure, easy to use, the adjustable angle between left panel, right panel and the main panel so can overcome reflective strong problem, makes the student of each position in the classroom can both see the content on the blackboard clearly.

Symbol description:
1. main panel, 2. right-hand rotation moving axis, 3. right panel, 4. left-hand rotation moving axis, 5. left panel, 6. right panel angular adjustment button, 7. left panel angular adjustment button.
The specific embodiment
Below in conjunction with accompanying drawing and instance the utility model is described further:
As depicted in figs. 1 and 2; A kind of reflection prevention blackboard of present embodiment; Form by main panel 1, right panel 3 and left panel 5; Said right panel 3 is positioned at main panel 1 right side and is rotationally connected through right-hand rotation moving axis 2 and main panel 1, and said left panel 5 is positioned at main panel 1 and passes on left left-hand rotation moving axis 4 and be rotationally connected with main panel 1, and said right-hand rotation moving axis 2 is connected with motor with left-hand rotation moving axis 4; Said main panel 1 is provided with right panel angular adjustment button 6 and left panel angular adjustment button 7, and the break-make of said motor is controlled with turning to by right panel angular adjustment button 6 and left panel angular adjustment button 7.
When blackboard reflective light is strong; Break-make through pressing right panel angular adjustment button 6 or left panel angular adjustment button 7 control motor with turn to; Left-hand rotation moving axis 4 or right-hand rotation moving axis 2 are rotated; Thereby adjustment left panel 5 or right panel 3 and the angle that main panel 1 is overcome the strong problem of blackboard reflective light.
With way of example the utility model is illustrated above, but the utility model is not limited to above-mentioned specific embodiment, all any changes done based on the utility model or modification all belong to the utility model and require the scope protected.
