Description

Mathematics is drawn and is measured multipurpose ruler
Technical field
The utility model belongs to teaching apparatus, refers in particular to a kind of Multifunctional mathematics teaching device.
Background technology
In mathematical education, particularly in the mathematical education process of middle and primary schools, in order to make the class teaching content of understanding that student is more prone to, teacher need to carry out manual drawing on blackboard, and so just causing ruler, compasses and protractor to become is one of instrument indispensable in mathematical education.But, traditional mathematics drawing instrument is for example: ruler, compasses, protractor normally independently arrange, and teacher, in the time of graphing, need to change drawing apparatus according to the needs of drawing conventionally, mapping will cumbersome complexity like this, brings a lot of inconvenience to teacher's picture.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model be to provide a kind of easy to use, both can be used in combination, multipurpose ruler is measured in can mathematics drawing of also can independently using.
For achieving the above object, the utility model comprises ruler, two protractors, described protractor is provided with angle index, it is characterized in that: described ruler comprises rotary ruler and positioning rule, this positioning rule comprises two long limits and two minor faces that are connected two long limits, the back side, one end of this positioning rule is fluted, is provided with sucker in groove; The centre of described positioning rule is provided with the kidney slot paralleling with long limit, the hinged slide block in described rotary ruler one end, and slide block is stuck in kidney slot, the detachable chalk that is equipped with of the other end of described rotary ruler; Two long limits of described positioning rule are respectively top margin and base, and described base is marked with length scale, and described top margin is provided with two parallel chutes; Two protractors are embedded in respectively in described chute, and described protractor can be moved in described positioning rule, and spacing between two protractors is greater than the thickness of this rotary ruler, and rotary ruler is between two protractors.
On the basis of such scheme, preferably, described protractor comprises the module extender board that is the Angle protractor of semi-annular shape and connects described Angle protractor two ends, and described module extender board embeds in chute.
On the basis of such scheme, preferably, described slide block is cylinder.
On the basis of such scheme, preferably, described chalk is arranged on the pen cap, and the pen cap is arranged on rotary ruler end.
The utility model compared with prior art, its beneficial effect is: the utility model has overcome mathematics drawing instrument in traditional concept to be separated the artificial combination that needs that independent design causes and use the difficulty of bringing, simultaneously, having solved existing combined type mathematics drawing instrument can not dismantle caused teacher and use for a long time, the defect consuming one's strength, not only can realize being used in combination of ruler and protractor and draw quantitative angle, but also can realize ruler and protractor separate independent measurement and use; Simultaneously, in the centre of positioning rule, one kidney slot is set, what can relative positioning chi move by hinge rotary ruler one end is arranged in this kidney slot, the detachable chalk that is equipped with of the other end of this rotary ruler, and be provided with a sucker in positioning rule one end, can complete the drafting of circle or radian, in the time rotary ruler being turned to positioning rule at same linear position, also can increase the drafting of straight line or measure length, having avoided when user is during at the longer straight line of picture, that need move ruler causes the not straight problem of setting-out.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is side view of the present utility model;
In figure: 10. ruler, 11. rotary rulers, 12. positioning rules, 13. kidney slots, 14. suckers, 15. cylindrical sliders, 16. chalks, 17. chutes, 20. protractors.
The specific embodiment
By describe in detail the utility model technology contents, structural feature, reached object and effect, below hereby exemplify embodiment and coordinate accompanying drawing to be explained in detail.
Refer to Fig. 1, and in conjunction with consulting shown in Fig. 2, the utility model comprises ruler 10, two protractors 20, protractor 20 is provided with angle index, ruler 10 comprises rotary ruler 11 and positioning rule 12, positioning rule 12 comprises two long limits and two minor faces that are connected two long limits, and the back side, one end of positioning rule 12 is fluted, is provided with sucker 14 in groove; The centre of positioning rule 12 is provided with the kidney slot 13 paralleling with long limit, the hinged cylindrical slider 15 in rotary ruler 11 one end, and cylindrical slider 15 is stuck in kidney slot 13, and the other end of rotary ruler 11 is installed the pen cap, and chalk 16 is installed in the pen cap; Two long limits of positioning rule 12 are respectively top margin and base, and base is marked with length scale, and top margin is provided with two parallel chutes 17; Two protractors 20 are embedded in respectively in chute 17, and protractor 20 can be moved in positioning rule 12, and the spacing between two protractors 20 is greater than the thickness of rotary ruler 12, and rotary ruler 11 is between two protractors 20, and total is more stable.
Each protractor 20 comprises the Angle protractor that is semi-annular shape and the module extender board that connects Angle protractor two ends, and module extender board embeds in chute 17.
In sum, be only the preferred embodiment of the utility model, do not limit protection domain of the present utility model with this, all equivalences of doing according to the utility model the scope of the claims and description change and modify, within being all the scope that the utility model patent contains.
