Description
Technical field
This utility model is related to a kind of College Mathematics Teaching teaching aid.
Background technology
It is frequently necessary to during mathematical education coordinate axess are drawn on blackboard or circle is divided into some to show not
Same material ratio shared wherein, due to not having special instrument, teacher is usually directly to be drawn on blackboard with handss, paints
Make that the figure coming is not up to standard, if particularly circle is divided into during stem portion be usually teacher distribution directly perceived, will result in figure
Distribute inaccurate in shape.In addition, teacher needs to hold drawing instrument always when drawing, slightly offset, drawing structure can be caused
Inaccurate,, for the test that teacher is in muscle power and level, leading to can be very tired out during teacher's drawing for this.
Utility model content
The technical problems to be solved in the utility model be provide a kind of structure be simple and convenient to operate, safe university
Mathematical teaching aid.
For solving the above problems, this utility model adopts the following technical scheme that
A kind of College Mathematics Teaching teaching aid, including cross bar, perpendicular chi, moving guide rail, Mobile base, board of education, circle chi, rotation
Chi, slideway and chalk sleeve hole, described cross bar is provided with moving guide rail, and described moving guide rail is provided with Mobile base, described shifting
It is connected with perpendicular chi below dynamic seat, described cross bar is provided with slideway, described cross bar is connected by slideway and is provided with religion
Learn plate, described vertical ruler lower end head is provided with rotary shaft, described perpendicular chi is flexibly connected by rotary shaft and is provided with round chi and rotation
Chi, the lower end of described rotation chi is provided with chalk sleeve hole, and described rotation chi is separately positioned on the upper of round chi by rotary shaft
Side and lower section, described rotation chi is connected with chalk by chalk sleeve hole, and described board of education is detachable.
It is provided with crossfoot on described cross bar front end face, described cross bar one end is connected with lever.
Preferably, being provided with graduation mark on described perpendicular chi, circle chi and rotation chi.
Preferably, described rotation chi carries out 360 degree on perpendicular chi by rotary shaft and arbitrarily rotates.
This utility model reasonable in design, easy for operation, on cross bar, setting moving guide rail and slideway connect respectively
Connect the perpendicular chi of setting and board of education, perpendicular chi traverse measurement drawing can be operated by Mobile base, in addition board of education can be torn open
Unload operation；Achieve measurement of can painting on the teaching board it is also possible to be operated on other blackboard；In addition under perpendicular chi
End rotates chi and circle chi by rotary shaft connect setting, arranges chalk sleeve hole on rotation chi；Rotation chi passes through rotary shaft perpendicular
Carry out 360 degree on chi arbitrarily to rotate；Coordinate axess and related drawing operation can be achieved；And realize pie chart and segmentation
Drawing operation, greatly improve efficiency of giving lessons, there is very big using value.
