Abstract

The utility model relates to a multi-purpose ruler with a sucker which is characterized in that the ruler is composed of a ruler and a rectangular vertical slide way. The rectangular vertical slide way is divided into three layers: the upper layer is composed of four isosceles right-angled triangle plates; the middle layer is composed of four isosceles sector plates with right angles; the bottom plate of the slide way is composed of the round protractor with a central hole. The upper layer and the middle layer are successively bonded on the bottom plate of the slide way to compose slide ways which are mutually vertical. The four angles on the front face and the back face of the rectangular vertical slide way are all provided with suckers. The side lateral of the ruler is provided with a graduation line. The surface of the ruler is provided with a through hole. Two screw rods penetrate through the through hole. The lower end of one screw rod is fixed in the transverse slide way of a rectangular vertical slide way plate, and the lower end of the other screw rod is fixed in the vertical slide way of the rectangular vertical slide way plate. The multi-purpose ruler can be used for drawing pictures accurately and rapidly and for drawing ellipses, regular polygons and equally divided circles and for measuring length and is beneficial to the rapid finishing of the teaching tasks of teachers.

Description

The multipurpose ruler rule of band sucker

Technical field

The utility model relates to a kind of teaching aid, particularly relates to a kind of multipurpose ruler rule with sucker, is to the improvement of existing ruler structure, belongs to school supply and stationery.

Background technology

At present; people draw the teaching aid of round usefulness usually, and function singleness can only be used separately; carry inconvenience; be difficult for placing, and very not nimble at the blackboard upper drawing circle, particularly also there is not the special oval teaching aid of drawing; drawing ellipse during drawing can only draw oval with the method for altering course with a concentric circle or the approximate technique of painting; not only time-consuming but also require great effort, that draws is oval of low quality, is unfavorable for that the teacher makes full use of time in classroom and finishes teaching task quickly and easily.

The utility model content

The purpose of this utility model is to overcome the prior art above shortcomings, by existing picture is justified the improvement of the teaching aid structure of usefulness, provide a kind of multipurpose ruler rule with sucker, these novel multipurpose ruler rule, not only draw accurately, fast, can also draw ellipse, regular polygon, Equal round, rule is energy length also, the time spent can arbitrarily not make its side that is adsorbed on blackboard, helps the teacher and finishes teaching task quickly.

The technical scheme that the utility model provides is: the multipurpose ruler rule of this band sucker, be characterized in constituting by the vertical slideway of ruler with rectangle, and the vertical slideway of wherein said rectangle divides three layers: the upper strata is a chute board, is made of four isosceles right-angled triangle plates; The intermediate layer is that the opaque isosceles fanning strip at four band right angles constitutes, and its limit along slideway is littler 2～3 millimeters than the limit of chute board; The slideway base plate is made of the circular protractor of 360 degree of a band centre bore; Wherein chute board, intermediate layer are glued to successively and constitute mutually perpendicular slideway on the slideway base plate, be equipped with sucker on four angles of the front and back of the vertical slideway of described rectangle, the side of described ruler is provided with graduation mark, the chi face is provided with an exhausting hole, be installed with two screw rods in the through hole, wherein the lower end of a screw rod is fixed in the transverse slipway of the vertical chute board of rectangle, the lower end of another root screw rod is fixed in the end slipway of the vertical chute board of rectangle, thereby ruler can be slided in the slideway of the vertical chute board of rectangle.

Compared with prior art, the beneficial effects of the utility model are: it is accurate, quick not only to draw, and can also draw ellipse, regular polygon, Equal round, and rule is energy length also, helps the teacher and finish teaching task quickly.

The specific embodiment

As shown in Figure 1-Figure 3, the multipurpose ruler of this band sucker rule are made of the vertical slideway 2 with rectangle of ruler 1, and wherein the vertical slideway of rectangle 2 minutes is three layers: upper strata chute board 3 is made of four isosceles right-angled triangle plates; Intermediate layer 4 is that the opaque isosceles fanning strip at four band right angles constitutes, and its limit along slideway is littler 2～3 millimeters than the limit of chute board; Slideway base plate 5 is made of the circular protractor of 360 degree of a band centre bore; Chute board 3, intermediate layer 4 are glued to the mutually perpendicular slideway of formation on the slideway base plate 5 successively at the middle and upper levels for they, be equipped with sucker 6 on four angles of the front and back of the vertical slideway 2 of described rectangle, the side of described ruler 1 is provided with graduation mark, the chi face is provided with an exhausting hole 7, be installed with two screw rods in the through hole 7, wherein the lower end of a screw rod 8 is fixed in the transverse slipway 9 of the vertical chute board 2 of rectangle, the lower end of another root screw rod 10 is fixed in the end slipway 11 of the vertical chute board 2 of rectangle, thereby ruler 1 can be slided in the slideway of the vertical chute board 2 of rectangle.

Draw bowlder, only the lower end with a bolt is fixed in the centre bore of the vertical chute board 2 of rectangle, make it the fixedly center of circle of elder generation, again pencil 12 is inserted in the through hole 7 of rulers 1, rotate ruler 1 and draw circle, clockwise, being rotated counterclockwise can, if draw the circle of different sizes, pencil 4 can be inserted in the different through holes 6 of rulers 1,, rotate ruler 1 circles of different sizes that can draw again to adjust scale.

When drawing ellipse, earlier the lower end of two bolts 8,10 is penetrated in the through hole 7 of ruler 1 setpoint distance (length semiaxis poor), and in the slideway of the vertical chute board 2 of the rectangle of packing into, pencil 12 is inserted in the through hole 7 of ruler 1, reserve the distance of pencil 12 and two bolts 8,10, after being the length of length semiaxis, rotating ruler 1 one and enclose the ellipse that promptly drawn.

Claims (1)
