Abstract
A kind of mathematical education curve drawing device, belongs to instructional device field.The utility model comprises curved supporter, curved supporter is divided into two parts, be respectively upper curve support and lower curve support, upper curve support and lower curve support hinged, hinged place arranges support open-and-close mechanism, and upper curve support and lower curve support are respectively equipped with symmetrical curved groove, mutually through between curved groove, the curvature of curved groove junction is 1, arranges slide block in curved groove, and the lower end of slide block arranges separable paintbrush or chalk.The utility model can adjust the opening degree of upper curve support and lower curve support by adjusting pole open-and-close mechanism, thus realizes the opening degree of curve, very convenient, and the curve drawn also comparatively standard, can improve the quality of instruction of math teacher.
Description
Technical field
The utility model belongs to instructional device field, especially with a kind of mathematical education curve drawing device.
Background technology
Math teacher, when trace (such as hyperbola etc.), normally free-handly directly to be drawn on the carriers such as blackboard, and owing to being hand operation, curve can exist deviation unavoidably, thus affects quality of instruction.Therefore a kind of mathematical education curve drawing device has been opened in applicant research, is intended to the picture quality improving curve.
Summary of the invention
For above-mentioned defect, the utility model provides a kind of mathematical education curve drawing device of drawing simplicity.
For this reason, the utility model is by the following technical solutions: a kind of mathematical education curve drawing device, comprise curved supporter, curved supporter is divided into two parts, be respectively upper curve support and lower curve support, upper curve support and lower curve support hinged, hinged place arranges support open-and-close mechanism, upper curve support and lower curve support can be made to open along hinged place by adjusting pole open-and-close mechanism or closed, upper curve support and lower curve support are respectively equipped with symmetrical curved groove, mutually through between curved groove, the curvature of curved groove junction is 1, thus make the curve that two curved grooves coordinate formation smooth, in curved groove, slide block is set, slide block can slide along curved groove, the lower end of slide block arranges separable paintbrush or chalk, thus slide block can be made on blackboard or blank, to draw curve at sliding process.
Use the utility model can reach following beneficial effect: the utility model is by upper curve support and lower curve holder combination forming curves support, by arranging curve chute on upper curve support and lower curve support, slide block is set in curve chute, makes paintbrush or chalk draw curve on the carriers such as blackboard by skid.Can be adjusted the opening degree of upper curve support and lower curve support by adjusting pole open-and-close mechanism, adjustment realizes the opening degree of curve, very convenient, and the curve drawn also comparatively standard, can improve the quality of instruction of math teacher.
Accompanying drawing explanation
Fig. 1 is schematic front view of the present utility model.
Fig. 2 is schematic side view of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
Embodiment: as shown in Fig. 1 ~ Fig. 2, the utility model comprises curved supporter, curved supporter is divided into two parts, be respectively upper curve support 1 and lower curve support 2, upper curve support 1 and lower curve support 2 hinged, hinged place arranges support open-and-close mechanism 4, upper curve support 1 and lower curve support 2 can be made to open along hinged place by adjusting pole open-and-close mechanism 4 or closed, upper curve support 1 and lower curve support 2 are respectively equipped with symmetrical curved groove 3, mutually through between curved groove 3, the curvature of curved groove 3 junction is 1, thus make the curve that two curved grooves coordinate formation smooth, slide block 5 is set in curved groove 3, slide block 5 can slide along curved groove 3, the lower end of slide block 5 arranges separable paintbrush 6 or chalk, thus slide block 5 can be made on blackboard or blank, to draw curve at sliding process.
Further, support open-and-close mechanism 4 comprises adjustment runner, and described upper curve support 1 and lower curve support 2 are respectively equipped with and the driven runner adjusting runner and coordinate, and by rotating adjustment runner, can realize the opening and closing of upper curve support 1 and lower curve support 2.
As preferably, support open-and-close mechanism 4 is arranged at the sidepiece of curved groove 3.
The utility model is by upper curve support and lower curve holder combination forming curves support, by arranging curve chute on upper curve support and lower curve support, slide block is set in curve chute, makes paintbrush or chalk draw curve on the carriers such as blackboard by skid.Can be adjusted the opening degree of upper curve support and lower curve support by adjusting pole open-and-close mechanism, thus adjustment realizes the opening degree of curve, very convenient, and the curve drawn also comparatively standard, the quality of instruction of math teacher can be improved.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
