The teacher can be with the help of setting -out hole paint out the fast abscissa and the ordinate of coordinate axle during the use to according to the scale coordinate scale that draws, transverse ruler can freely move erecting chi one side, can help the teacher to find the position that function curve is ordered in the coordinate system quickly accurate, has improved drawing efficiency.
Description
Technical field
The utility model relates to teaching apparatus field, in particular to a kind of higher mathematics coordinate plot device.
Background technology
In the teaching process of higher mathematics, teacher often needs to draw coordinate diagram on blackboard, explains various curvilinear function. Use the ruler of common mathematics teaching or set square draws coordinate axis and function curve is often very inconvenient, it is very difficult to accurately determine the position of each point in function curve according to coordinate axis numerical value, drawing gets up and expended the long time, have impact on teaching process.
Practical novel content
Technical problem to be solved in the utility model is to provide a kind of higher mathematics coordinate plot device, the perpendicular chi connected by projection and chute by design and horizontal chi, horizontal chi can be free to slide on perpendicular chi, so that the position of each point in function curve of painting out quickly and accurately.
For achieving the above object, the utility model provides following technical scheme: a kind of higher mathematics coordinate plot device, it is characterized in that: described higher mathematics coordinate plot device comprises the perpendicular chi of the length rectangle strip all identical with thickness and horizontal chi, perpendicular chi and horizontal chi are all carved with scale, perpendicular chi and horizontal chi center all have the setting-out hole of arrow-shaped, the side of perpendicular chi has the T-shaped chute in cross section, chute inwall is fixed with inner liner, one end of horizontal chi is provided with the T-shaped projection in cross section, and the mutual shrink-fit of the chute of the projection of horizontal chi and perpendicular chi.
Preferably, described horizontal chi, perpendicular chi, projection be by aluminium alloy manufacture.
Preferably, the length of described chute is equal with the length of perpendicular chi.
Preferably, described inner liner is manufactured by elastomeric material, and the length of inner liner is equal with the length of chute.
Preferably, described projection and horizontal chi are one-piece construction, and behind projection loading chute inside, horizontal chi is mutually vertical with perpendicular chi.
The useful effect of above technical scheme is adopted to be: perpendicular chi and the horizontal chi of this higher mathematics coordinate plot device are all carved with scale, perpendicular chi and horizontal chi center all have the setting-out hole of arrow-shaped, the side of perpendicular chi has chute, chute inwall is fixed with inner liner, one end of horizontal chi is provided with projection, and convex ring and chute shrink-fit. During use, teacher can paint out by setting-out hole the X-coordinate of coordinate axis and ordinate zou fast, and draw coordinate scale according to scale, horizontal chi can move freely in perpendicular chi side, teacher can be helped to find the position of function curve point in system of coordinates quickly and accurately, it is to increase drawing efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of a kind of higher mathematics coordinate plot device of the utility model;
Fig. 2 is the structure enlarged diagram of perpendicular chi and horizontal chi junction shown in Fig. 1.
Wherein, 1-perpendicular chi, the horizontal chi of 2-, 3-setting-out hole, 4-scale, 5-projection, 6-chute, 7-inner liner.
Embodiment
The preferred implementation of a kind of higher mathematics coordinate plot device of the utility model is described in detail below in conjunction with accompanying drawing.
Fig. 1 with Fig. 2 shows the embodiment of the utility model a kind of higher mathematics coordinate plot device: this higher mathematics coordinate plot device comprises the perpendicular chi 1 of the length rectangle strip all identical with thickness and horizontal chi 2, perpendicular chi 1 and horizontal chi 2 are all carved with scale 4, perpendicular chi 1 and horizontal chi 2 center all have the setting-out hole 3 of arrow-shaped, can by this plotter unit by blackboard, pen is extend in setting-out hole 3, just can draw coordinate axis X-coordinate and the ordinate zou of band arrow fast.
As shown in Figure 2, the side of perpendicular chi 1 has the T-shaped chute in cross section 6, chute 6 inwall is fixed with inner liner 7, one end of horizontal chi 2 is provided with the T-shaped projection in cross section 5, and the projection 5 of horizontal chi 2 shrink-fit mutual to the chute 6 of perpendicular chi 1, in conjunction with closely, it is that horizontal chi 2 not easily falls down in perpendicular chi 1 side slip, convenient drawing.
Composition graphs 1 and Fig. 2, horizontal chi 2, perpendicular chi 1, projection 5 are by aluminium alloy manufacture, sturdy and durable, and non-corrosibility is good. The length of chute 6 is equal with the length of perpendicular chi 1, and inner liner 7 is manufactured by elastomeric material, and the length of inner liner 7 is equal with the length of chute 6 so that horizontal chi 2 can reach maximum at perpendicular chi 1 sliding scale.
Projection 5 and horizontal chi 2 are one-piece construction, and after projection 5 loads chute 6 inside, horizontal chi 2 is mutually vertical with perpendicular chi 1, applicable rectangular coordinate system of painting out, x-axis in the corresponding rectangular coordinate system of horizontal chi 2, y-axis in the corresponding rectangular coordinate system of perpendicular chi 1, it is to increase drawing efficiency, has saved the time that middle drawing of attending class takies.
Upper class hour, teacher can paint out by setting-out hole 3 X-coordinate of coordinate axis and ordinate zou fast, and draw coordinate scale according to the scale 4 on perpendicular chi 1 and horizontal chi 2, horizontal chi 2 can move freely in perpendicular chi 1 side, the teacher can be helped, it is to increase drawing efficiency to find the position of function curve point in system of coordinates quickly and accurately.
Above is only preferred implementation of the present utility model; it is noted that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also making some distortion and improvement, these all belong to protection domain of the present utility model.
