Abstract
The utility model discloses a mathematics teaching dividing ruler. The mathematics teaching dividing ruler comprises a horizontal ruler and a vertical ruler, wherein the vertical ruler is fixed at one end of the horizontal ruler and perpendicular to the horizontal ruler. The horizontal ruler is provided with a gradienter, length scales and a hanging hole. The mathematics teaching dividing ruler has the advantages that structure is simple; the horizontal ruler is provided with the gradienter so that the gradienter can be used for adjusting the horizontal ruler to of a horizontal state, qualified horizontal lines can be drawn, the vertical ruler is perpendicular to the horizontal ruler so that qualified vertical lines can be drawn through the vertical ruler, and operation is convenient; and the horizontal ruler is provided with the hanging hole so that hanging is convenient.
Description
Technical field
The utility model relates to a kind of teaching apparatus for mathematics, particularly a kind of mathematical education rule.
Background technology
In the process of school mathematics teaching, the teacher draws well a lot of horizontal lines and vertical curve usually, but existing ruler is owing to lacking object of reference, thereby is difficult to horizontal line and the vertical curve of the standard of drawing out, and is very inconvenient.
Summary of the invention
Problem to be solved in the utility model is: a kind of simple in structure, mathematical education rule of being convenient to draw horizontal line and vertical curve is provided.
In order to solve the problems of the technologies described above, mathematical education rule of the present utility model, comprise horizon rule and be fixed on horizon rule one end with the perpendicular vertical chi of horizon rule, described horizon rule is provided with a level meter, described horizon rule is provided with the length scale.
For the ease of hanging, mathematical education rule of the present utility model, described horizon rule are provided with a hanging hole.
The beneficial effect that the utility model is obtained is: (1) is simple in structure; (2) horizon rule is provided with a level meter, thereby horizon rule can be adjusted to level by level meter, thereby draws out qualified horizontal line, and vertical chi and horizon rule are perpendicular, thereby can draw out qualified vertical curve by vertical chi, and is very convenient; (3) horizon rule is provided with a hanging hole, is convenient to hang.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1, length scale, 2, level meter, 3, horizon rule, 4, vertical chi, 5, hanging hole.
The specific embodiment
As shown in Figure 1, mathematical education rule of the present utility model, comprise horizon rule 3 and be fixed on horizon rule 3 one ends with the perpendicular vertical chi 4 of horizon rule 3, described horizon rule 3 is provided with a level meter 2, described horizon rule 3 is provided with length scale 1; Described horizon rule 3 is provided with a hanging hole 5.
Mathematical education rule of the present utility model, simple in structure, horizon rule 3 is provided with a level meter 2, thereby horizon rule 3 can be adjusted to level by level meter 2, thereby draw out qualified horizontal line, and vertically chi 4 is perpendicular with horizon rule 3, thereby can draw out qualified vertical curve by vertical chi 4, and is very convenient.
Mathematical education rule of the present utility model, horizon rule 3 are provided with a hanging hole 5, are convenient to hang.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
