CN202428935U - Ruler for mathematics teaching - Google Patents

Abstract

The utility model discloses a teaching appliance, and particularly discloses a ruler for mathematics teaching. The ruler for mathematics teaching comprises a ruler body and graduations on the ruler body, an electronic level gauge is mounted in the middle of the ruler body, a pointer and a graduated disc are disposed in the electronic level gauge, and protractors are respectively mounted at two ends of the ruler body. The ruler for mathematics teaching can be used for drawing horizontal lines without the aid of other auxiliary tools, and is operated simply and conveniently. Besides, angular lines can also be drawn by the aid of the protractors of the ruler, and teaching smoothness and teaching efficiency can be greatly enhanced.

Description

A kind of mathematical education is used ruler

(1) technical field

The utility model relates to a kind of realia, and particularly a kind of mathematical education is used ruler.

(2) background technology

Math teacher is being said class hour to the student, often can use ruler, all is with ruler after the vertical placement with set square now when drawing horizontal linear, the horizontal line that draws, and troublesome poeration, the while, present ruler was not drawn the function of angle yet.

(3) summary of the invention

The utility model provides a kind of mathematical education of drawing horizontal line and angle line to use ruler in order to remedy the defective of prior art.

The utility model is realized through following technical scheme:

A kind of mathematical education is used ruler, comprise ruler and on scale, it is characterized in that: ruler middle part is equipped with electrolevel, establishes pointer and dial in the electrolevel, and the ruler two ends are separately installed with protractor.

The beneficial effect of the utility model is: this mathematical education is used ruler, need not other aid horizontal line that can draw, and is easy and simple to handle, carries the protractor angle line that can draw simultaneously, can improve greatly give lessons fluency with give lessons efficient.

(4) description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Accompanying drawing 1 is the structural representation of the utility model mathematical education with ruler.

Among the figure, 1 ruler, 2 scales, 3 protractors, 4 electrolevels, 5 pointers, 6 dials.

(5) specific embodiment

Accompanying drawing is a kind of specific embodiment of the utility model.

Among Fig. 1, this mathematical education is used ruler, comprise ruler 1 and on scale 2, ruler 1 middle part is equipped with electrolevel 4, establishes pointer 5 and dial 6 in the electrolevel 4, ruler 1 two ends are separately installed with protractor 3.When drawing horizontal line or vertical curve, only need to get final product through regulating the centre position setting-out that pointer 5 that ruler 1 make electrolevel 4 points to dials 6, draw angle line if desired, then the angle line that just can draw arbitrarily of the protractor 3 through both sides is very easy to use.

Claims (1)

1. a mathematical education is used ruler; Comprise ruler (1) and on scale (2); It is characterized in that: ruler (1) middle part is equipped with electrolevel (4), establishes pointer (5) and dial (6) in the electrolevel (4), and ruler (1) two ends are separately installed with protractor (3).
