The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1, the utility model embodiment is provided with dial (ruler of strip length scale mark) 11,12 and 2 screws 13 of conductor rope (inelastic conductor rope); The length scale mark of dial 11 is for being symmetrical set, and dial 11 middle parts are provided with 111,2 screws 13 of vertical guide groove and all are slidingly matched with guide groove 111, and the two ends of conductor rope 12 tie up to respectively on 1 screw 13.Conductor rope 11 is provided with length scale mark (also can not having the length scale mark).
Said dial 11 is embedded with magnet (magnet does not draw), and magnet is convenient to and the blackboard adhesive.
This embodiment is suitable for the teacher to be used.During use, dial 11 is pull-in on the blackboard.
Draw when oval, as shown in Figure 1, move the position of 2 screws 13 and through nut 131 lockings, 2 screws 13 are left-right symmetric, and chalk P near conductor rope 12, is moved chalk, the oval F1 that promptly drawn (among Fig. 1 shown in the double dot dash line).The position of 2 screws 13 can be adjusted as required, thereby can draw the ellipse of different curvature.
If will draw circle, 2 screws 13 are all inwardly moved to scale locate for " 0 ", 2 screws 13 are drawn close, and 2 screws 13 drawing close are regarded as a fixed point (being the center of circle), with chalk P near conductor rope, mobile chalk, the round F2 that promptly draws (among Fig. 1 shown in the double dot dash line).Change the length of conductor rope, can draw the circle of different sizes.
If will draw hyperbola, the distance between 2 Luo silks 13 is drawn back, according to scale mark 2 Luo silks 13 are positioned at symmetrical 2 points respectively; Be fixed on conductor rope 12 (conductor rope employing slide fastener) two ends on 2 Luo silks then and make slide fastener the right grow the left side and lack, near in the middle of the slide fastener, slowly unzip with chalk; Prop up on the hyp left side of can drawing, exchange slide fastener end positions, in like manner; Make long the right, slide fastener 12 left sides short, slowly unzip 12, right of the hyperbola that can draw.(among Fig. 1 shown in the double dot dash line) so just can draw hyperbola F3.
Referring to Fig. 2, similar with embodiment 1, difference is: dial 11 ' be the drawing board of strip length scale mark is suitable for the student and uses.Dial 11 ' be equivalent to the dial (ruler of strip length scale mark) 11 of embodiment 1 ' with the combination of blackboard.Draw circle, ellipse, the hyp technique of painting with embodiment 1.All the other labels among Fig. 2 are corresponding consistent with embodiment 1.
Referring to Fig. 3, similar with embodiment 1, difference is: on the basis of embodiment 1, increased secondary dial 14.Secondary dial 14 is provided with the length scale mark, and the length scale mark is for being symmetrical set up and down.One end of conductor rope 12 ties up on 1 screw 13, and conductor rope 12 other ends are free end.Conductor rope 12 is provided with length scale mark (not shown).It is other that secondary dial 14 is located at master calibration spare 11, and secondary dial 14 forms the setting of T font with master calibration spare 11.
Present embodiment is suitable for the teacher to be used, and not only possesses embodiment 1 described picture circle, oval, hyp function (only need use master calibration spare 11, with embodiment 1), also can be by the secondary dial 14 parabola F5 that draws.The technique of painting of parabola F5 is following:
Master calibration spare 11 (is the ruler of band scale mark; Be embedded with magnet, magnet does not draw) suction places on the blackboard, (is the ruler of band scale mark with secondary dial 14; Be embedded with magnet) inhale and to put on blackboard and to be positioned at master calibration spare 11 other, make secondary dial 14 and master calibration spare 11 form the settings of T font.Secondary dial 14 is regarded as boning out.One end of conductor rope 12 is tied up on the screw 13 in left side, and conductor rope 12 other ends are untied and are free end.With chalk P nib near conductor rope 12; And the distance that makes chalk point to Luo silk 13 (fixed point) equals the distance (can show through the scale mark on the conductor rope 12) of chalk point to secondary dial 14 (boning out); So just fixed (retouching) goes out 1 point; And successively method at interval one by one fixed (retouching) go out more some points, each point is connected can form parabola F5 then.Change the position (secondary dial 14 is placed by master calibration spare 11 right sides) of master calibration spare 11 and secondary dial 14, the different parabola of opening direction just can draw.If move Luo silk 13, change Luo silk 13 fixed positions, the parabola of the different curvature of then can drawing.
Referring to Fig. 4, similar with embodiment 3.Difference is: the master calibration spare 11 of embodiment 2 ' both side edges increased symmetrically arranged length scale mark up and down; Be equivalent to increase secondary dial 14 ', be secondary dial 14 ' with said master calibration spare 11 ' be same one (be secondary dial 14 ' be equivalent to master calibration spare 11 ' lateral margin).Like this by the method for embodiment 3 parabola that can draw.Circle, oval, hyperbola (technique of painting is with embodiment 1) equally also can draw.
