Abstract
The utility model discloses a multifunctional rule, belonging to teaching aids. The multifunctional ruler is characterized in that length marks are formed on one side edge of a rectangular straight ruler, a plurality of troughs are formed on a ruler body of the rectangular straight ruler, a trough hole is formed at one end part of the ruler body, an inner sleeve is arranged in the through hole and can rotate in the through hole, and a sucker penetrates through the inner sleeve and is communicated with an air bag in a sealing way. The multifunctional ruler is simple in structure and convenient to use; when the ruler is used for drawing, the center of a circle is fixed firmly; and when a circle with a certain diameter is needed, the ruler can be used for drawing directly without measurement. As the length marks are arranged on the edge of the ruler body, a piece of chalk only needs to be directly put in the corresponding trough, and then the circle with the certain diameter can be drawn.
Description
Technical field:
The utility model belongs to realia, particularly a kind of multifunctional ruler.
Background technology:
At present, in several teaching, often will use ruler or compasses, Neither of the two can be dispensed.A wherein pin of now used compasses bipod is the center of circle, and fixing back rotary picture bowlder stitch moves easily on blackboard, and cumbersome when therefore mapping, the height of drawing in addition between the bowlder compasses bipod is also equally high, and is also more bothersome during adjustment.When running into teaching when the bowlder that needs the picture certain diameter, the distance that also needs this moment ruler to measure between the bipod could be mapped, and is more time-consuming during use.
The utility model content:
The utility model overcomes the deficiency of the problems referred to above, and a kind of multifunctional ruler is provided, and this ruler is simple in structure; Easy to use, the center of circle is fixed during mapping, when needing the big bowlder of certain diameter; Can directly map, no longer need to measure, this chi can also use as ruler simultaneously.This multifunctional ruler is achieved in that on the side edge of rectangle ruler and is provided with length indication; On the chi body of rectangle ruler, be provided with several draw-in grooves; End at the chi body is provided with through hole; Be provided with the interior cover that can in through hole, rotate in the through hole, be arranged with sucker in running through, sealing is communicated with air bag on the sucker.
The utility model is simple in structure, and is easy to use, and the center of circle is fixed during mapping, when needing the big bowlder of certain diameter, can directly map, and no longer needs to measure.Because the edge of chi body is provided with length indication,, chalk is placed directly in the corresponding draw-in groove gets final product therefore when the bowlder that needs the certain diameter size.
