Description
Technical field：
The utility model is related to a kind of teaching field, more particularly to a kind of Higher Mathematics Class teaching aid.
Background technology：
The teaching aid of present Higher Mathematics Teaching seldom, make teacher be difficult in teaching process intuitively explain it is clear, so
Explanation difficulty of the teacher on classroom is increased, the understanding difficulty of student is also increased, the picture of existing higher mathematics is auxiliary
Picture straight line, circle that apparatus can only be single are helped, so the clear-cut free-hand drawing by rule of thumb of teacher, the result is that the figure drawn is not advised very much
Then, student, which understands, gets up more muddled, existing to be badly in need of a kind of higher mathematics plotter.
The content of the invention：
The purpose of this utility model is to provide a kind of Higher Mathematics Class teaching aid.
Above-mentioned purpose is realized by following technical scheme：
A kind of Higher Mathematics Class teaching aid, its composition includes：Track support, described track support intersects anyhow
Dovetail slideway body, described slipway is in cross, in the end head peace of bottom surface four of the slipway of described track support
Equipped with sucker, it is equipped with respectively on sliding block A and slide block B, described sliding block A and slide block B in described track support top slipway
There is screw respectively, described sliding block is by the screw and mode connects for screw that have thereon, then passes through screw and the common work of pad
With can will draw bar and be connected on described sliding block A and slide block B, the cross sectional shape of sliding block is and dovetail slideway section
Identical swallow-tail form, pad is being drawn between bar and sliding block；
Described Higher Mathematics Class teaching aid, described picture bar is flat bar, thereon with three holes, two of which
At a distance of nearer for installing sliding block, it is used to paintbrush attachment screw and paintbrush are installed with the interstitial hole hole apart from each other in three holes,
Chalk or crayon are installed in described paintbrush.
Described Higher Mathematics Class teaching aid, described picture bar can be changed as needed, and described picture bar can
Linked together and used with several, can also will drawn bar and be fabricated to what length can be adjusted.
The beneficial effects of the utility model：
1. Higher Mathematics Class teaching aid of the present utility model, is easy to suction, easy to operate, drawing simplicity, effect can be improved
Rate, it is simple in construction.
Higher Mathematics Class teaching aid of the present utility model, overall structure is simple, easy for operation, can demonstrate effect
In the direction of the power on sliding block.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is structural representation of the present utility model（It is three-dimensional）.
In figure：1-track support；2-dovetail groove；3-sucker；4-sliding block A；5-slide block B；6-draw bar；7
- pad；8-screw；9-paintbrush attachment screw；10-paintbrush；11-chalk.
Embodiment：
Embodiment 1：
A kind of Higher Mathematics Class teaching aid, its composition includes：Track support, described track support 1 is to intersect anyhow
The slipway of dovetail groove 2, described slipway is in cross, in the end head of bottom surface four of the slipway of described track support
Be provided with sucker 3, described track support top slipway and be equipped with sliding block A 4 and slide block B 5 respectively, described sliding block A and
There is screw respectively, described sliding block is connected by the screw having thereon with screw 8, then passes through screw and pad 7 in slide block B
Collective effect, can will draw bar 6 and be connected on described sliding block A and slide block B, the cross sectional shape of sliding block is and dovetail groove
The cross section of slideway identical swallow-tail form, pad is being drawn between bar and sliding block.
Embodiment 2：
Higher Mathematics Class teaching aid according to embodiment 1, described picture bar is flat bar, thereon with three
Hole, two of which, for installing sliding block, is used to install paintbrush attachment screw 9 at a distance of nearer with sliding block interstitial hole hole apart from each other
With paintbrush 10, chalk 11 or crayon are installed in described paintbrush.
Described picture bar can be changed as needed, and described picture bar can be linked together with several to be used, and also may be used
It is fabricated to what length can be adjusted so that bar will be drawn.
