Abstract

The utility model relates to a multifunctional scale which is composed of an upper plate, a rotating plate and a base plate. The edge of the upper plate is provided with a plurality of graduations for measuring angles, and a hollow portion and a plurality of through holes of a triangle are arranged on the rotating plate which can be rotated between the upper plate and the base plate. Thus, multiple functions, such as line drawing, circle drawing, angle measurement, etc. are provided.

Description

Multifunctional ruler

The utility model relates to a kind of drawing article, and refer to a kind ofly have setting-out especially, draw circle and multinomial function such as take measurement of an angle, and structure, all quite simple multifunctional ruler of using method.

General illustrator during low-angle, must utilize drawing instruments such as ruler, compasses and protractor to be drawn in drawing straight line, circle and measuring, especially the student during mathematics class, above-mentioned drawing instrument is indispensable especially in school.And the drawing instruments of being sold on the market at present such as ruler, compasses and protractor are all sold with commodity independently, also are the independent mode of using during use.When illustrator's desire is drawn straight line, circle and is taken measurement of an angle, then must buy instruments such as ruler, compasses and protractor respectively, also must carry respectively when carrying, it not only causes the inconvenience of carrying, and does not more meet economic benefit.In view of this, now release on the market a kind of as Fig. 1 shown in isograph, though this isograph has the function of drawing multiple figure and taking measurement of an angle, but because the assembly of its formation is comparatively complicated, so that cost, price are higher, and the method for use is very loaded down with trivial details, makes illustrator (especially pupil) be difficult to grasp and do not know how to use, and makes this isograph have multinomial function in vain and but can't make the best use of everything.

Because above-mentioned drawing instrument can't be integrated, and commonly use the isograph complex structure, using method is loaded down with trivial details, so that produce above-mentioned various shortcoming, the purpose of this utility model is to provide a kind of multifunctional ruler, it is merged drafting straight line, circle and drawing instrument such as take measurement of an angle, and then have the picture straight line, draw circle and multiple function such as take measurement of an angle, and its structure, use-pattern are all quite simple and easy.

For achieving the above object, the utility model is taked following technical scheme:

A kind of multifunctional ruler, it is made up of dish, rolling disc and a chassis on one, wherein goes up dish, is a circular hollow disk body, and is arranged with a plurality of scales that take measurement of an angle in its dish edge etc.; Described rolling disc, be a circular disk body, and be provided with a protuberance in its card, this protuberance is provided with a triangle hollow-out parts, and make the center of circle of this leg-of-mutton long limit by rolling disc, be provided with a plurality of through holes in this protuberance again, and each through hole all is different distances with the center of circle of rolling disc; Described chassis is a circular disk body, and is arranged with formation one bearing groove thereon downwards, and this bearing groove just can be put for rolling disc, and the upper surface, chassis then can combine with the bottom surface of last dish.

Whereby, have setting-out to provide a kind of, draw circle and multinomial function such as take measurement of an angle, and contexture, all quite simple multifunctional ruler of use-pattern.

The utility model embodiment cooperates Fig. 2-Fig. 4 to be described in detail as follows:

Fig. 1 is a schematic perspective view of commonly using isograph.

Fig. 2 is a perspective exploded view of the present utility model.

Fig. 3 is a plane of the present utility model assembled sectional view.

Fig. 4 is the action synoptic diagram of overlooking of the present utility model.

See also Fig. 2,3, the utility model embodiment be by coil 10 on one, rolling disc 20 and a chassis 30 constitute, wherein:

Last dish 10, it is a circular hollow disk body, and is arranged with a plurality of scales that take measurement of an angle in its dish edge etc., is that to be set as transparence be preferable and should go up dish 10.

Rolling disc 20, it is a circular disk body, and be provided with a protuberance 21 in its card, this protuberance 21 is provided with leg-of-mutton hollow-out parts (also can be other geometric figure), and makes the center of circle of the long limit of this triangle (or geometric figure) by rolling disc 20, and is provided with the scale of size thereon, be provided with a plurality of through holes 22 in this protuberance 21 again, and each through hole 22 all is different distances with the center of circle of rolling disc 20, and in addition, this rolling disc 20 is that to be set as transparence be preferable.

Chassis 30, it is a circular disk body, and is arranged with formation one bearing groove 31 thereon downwards, and this bearing groove 31 just can be put for rolling

disc

20, and 30 upper surfaces, chassis then can combine with the bottom surface of last dish 10; In addition, to be set as transparence be preferable on above-mentioned chassis 30.

Combination (seeing also Fig. 4) by above-mentioned member, last dish 10 is with after chassis 30 combines, and 20 of rolling discs that are folded in central authorities can be in wherein rotating, and insert the through hole 22 of suitable radius distance by nib after, again rolling disc 20 is applied acting force and make its rotation, can go out a circle by unicursal; Again,, the line (center line of platen 20) that last dish 10 dish edge scales are 0 degree is aimed at the angle line that desire is measured, can know the angle of this angle by the scale on the last dish 10 if when desiring to take measurement of an angle; In addition, when drawing straight line, can utilize the long limit of being located at triangle on the rolling disc 20 (or geometric figure) to be drawn or measure straight-line dimension as if desire.

From the above and embodiment shown in the drawings as can be known, technological means that the utility model used and structure thereof really can reach the purpose of this creation, thereby providing a kind of has setting-out, draw circle and the chi of multiple function such as take measurement of an angle, and it has novelty, so meet the utility model patent important document.
