Teaching aid, the blackboard main body include two layers, respectively for write font the clipboard with plane rectangular coordinates and
The bottom plate only need to be on plane rectangular coordinates when higher mathematics teacher needs to draw parabola, circle or other function curves
Several characteristic points for marking required function can easily depict required figure.
In order to further increase Teaching efficiency, the clipboard, the bottom plate are fixed on the outline border by card slot
On, the writing plate surface is portrayed by the plane rectangular coordinates being made of the horizontal axis and the longitudinal axis, and the blackboard eraser passes through
The sliding slot is fixed on the outline border, and the outline border uses stainless steel punch forming.
In order to further increase Teaching efficiency, the inside of the support rod is embedded with the cavernous body, the sponge
Body is process using elastic material, and the support rod both ends are equipped with the idler wheel, the idler wheel installation by the fulcrum
In the sliding slot.
In order to further increase Teaching efficiency, the clipboard is that color coated steel sheet plate face is made, the bottom plate
It is made for solid wood board.
In order to further increase Teaching efficiency, the outline border is connect with the T-type bracket by the eyelet bolt,
The universal wheel is bolted with the T-type bracket, and the T-type bracket is process using stainless steel square tube.
In order to further increase Teaching efficiency, the outline border and the blackboard stores pylon are welded, the outline border with it is described
Welding hook.
In order to further increase Teaching efficiency, the width up and down of the lower-upper length of the cavernous body and the clipboard
It is equal.
Beneficial effect is: the utility model need to only be sat by portraying plane rectangular coordinates in clipboard in flat square
It puts on and marks several characteristic points of required function and can easily draw required figure, save non-drawing time, the utility model is set
The blackboard eraser that can be slided in blackboard front end is set, blackboard eraser lower-upper length is corresponding to the width up and down of blackboard main body, so wiping
The speed of blackboard is fast, and effect is good, and clipboard is color coated steel sheet plate face, wear-resisting, does not fall off, colour-fast, writes good hand touch, writing is clear
Clear, easy-to-write and erasable is wiped.
