Description
Technical field
This utility model is related to mathematics teaching aid technical field, more particularly to a kind of mathematical education drawing board.
Background technology
In mathematical education, it is often necessary to some figures are drawn on blackboard, due on existing blackboard no coordinate and
Grid, increased the difficulty of teacher's drawing, and the figure of drafting easily produces larger error, can affect the visual experience of student,
The observation of heel row student can be affected simultaneously, so as to affect teaching efficiency.
Utility model content
This utility model provides a kind of mathematical education drawing board, can carry out graphic plotting, keep away according to grid and coordinate
The figure for exempting to draw produces larger error, while being conducive to the observation of students figure of heel row.
This utility model provides a kind of mathematical education drawing board, including：Base plate, at least one piece sheet iron, printing opacity are painted
Chart board, light bar, Thin film cell and controlling switch, the edge of base plate are provided with frame, and at least one magnetic is fixed with base plate
Bar is inhaled, sheet iron is detachably connected with base plate by magnetism absorbent strip, the area of sheet iron is less than or equal to the area of base plate, sheet iron
Upper drafting has grid and coordinate, and scuncheon is provided with light bar and multiple support blocks, and light bar passes through controlling switch and wire and thin slice
Battery connects, and frame is provided with multiple positive stops, and printing opacity drawing board is arranged on by multiple support blocks and multiple positive stops
In frame, and positioned at the top of sheet iron.
Further, the Thin film cell is fixed between base plate and sheet iron, and controlling switch is arranged on frame.
Further, the plurality of positive stop is rotary stopper block.
Further, the upper end of the frame is additionally provided with least one hook.
Compared with prior art, the beneficial effects of the utility model are：
This utility model passes through printing opacity drawing board and light bar, it may be clearly seen that the grid and coordinate on sheet iron, together
When be also beneficial to heel row student viewing, lift teaching efficiency, it is by multiple support blocks and multiple positive stops, printing opacity drawing board is solid
It is fixed, there is in mathematics teacher the graphing on printing opacity drawing board, it is to avoid graphic plotting produces larger error, changes by magnetism absorbent strip
The sheet iron of different grids and coordinate, teacher can draw different figures, easy to use, or can splice simultaneously multiple thin
Iron plate, composition are conducive to the drafting of complex figure with different coordinates and the reference plate of grid, easy to use.
Description of the drawings
A kind of mathematical education drawing plate structure schematic diagram that Fig. 1 is provided for this utility model.
Description of reference numerals：
1- base plates, 2- sheet irons, 3- printing opacity drawing boards, 4- support blocks, 5- magnetism absorbent strips, 6- light bar, 7- positive stops, 8- are thin
Piece battery, 9- controlling switches, 10- hooks.
Specific embodiment
Below in conjunction with the accompanying drawings, a specific embodiment of the present utility model is described in detail, it is to be understood that this
The protection domain of utility model is not limited by specific embodiment.
As shown in figure 1, a kind of mathematical education drawing board that this utility model embodiment is provided, including：Base plate 1, at least
One piece of sheet iron 2, printing opacity drawing board 3, light bar 6, Thin film cell 8 and controlling switch 9, the edge of base plate 1 are provided with frame,
At least one magnetism absorbent strip 5 is fixed with base plate 1, sheet iron 2 is detachably connected with base plate 1 by magnetism absorbent strip 5, the face of sheet iron 2
Area of the product less than or equal to base plate 1, drawing on sheet iron 2 has grid and coordinate, and scuncheon is provided with light bar 6 and multiple supports
Block 4, light bar 6 passes through controlling switch 9 and wire is connected with Thin film cell 8, and frame is provided with multiple positive stops 7, and printing opacity is drawn
Plate 3 is arranged in frame by multiple support blocks 4 and multiple positive stops 7, and positioned at the top of sheet iron 2.
The base plate 1, sheet iron 2, printing opacity drawing board 3 are rectangle, and printing opacity drawing board 3 is focussing glass, and light bar 6 is two
Bar, is separately positioned on the both sides of rectangular shaped rim.
By printing opacity drawing board 3 and light bar 6, it may be clearly seen that the grid and coordinate on sheet iron 2, while being also beneficial to
Heel row student viewing, by multiple support blocks 4 and multiple positive stops 7, printing opacity drawing board 3 is fixed, is had and is existed in mathematics teacher
Graphing on printing opacity drawing board 3, it is to avoid graphic plotting produces larger error, changes different grids and coordinate by magnetism absorbent strip 5
Sheet iron 2, teacher can draw different figures, easy to use, or can splice multiple sheet irons 2 simultaneously, composition tool
There is the reference plate of different coordinates and grid, be conducive to the drafting of complex figure, it is easy to use.
Further, the Thin film cell 8 is fixed between base plate 1 and sheet iron 2, and controlling switch 9 is arranged on frame.
The position of Thin film cell 8 is conducive to the space for saving drawing board.
Further, the plurality of positive stop 7 is rotary stopper block.
