Abstract
The utility model relates to a multipurpose combined ruler, which is characterized in that the multipurpose combined ruler comprises a straight ruler with length scales and a circular protractor with angle scales, the straight ruler and the circular protractor are arranged into an integral body by a hollow shaft, and a slide block is sheathed and arranged on the straight ruler. Line segment, angle, circle or arc drawing can be realized, and points can also be taken on a rectangular coordinate system and a polar coordinate system to draw. The utility model has the advantages of more functions, easy use, wide ranges, fast drawing and measuring speed, etc. The utility model is especially suitable for teaching.
Description
Use combination ruler a kind of more, belong to measuring instrument, be particularly suitable for teaching and use.
Existing chi is used for setting-out section or linear measure longimetry; Existing protractor is used for angular surveying or draws angle by chi; Existing compasses are used for picture circle or arc.All exist function singleness, use deficiencies such as inconvenient and time-consuming.
The purpose of this utility model is to provide that a kind of function is many, easy to use, scope is wide, draws, measuring speed is fast uses combination ruler more.
The purpose of this utility model is realized by following technical scheme: a kind of combination rulers of using more, it is combination, improvement to prior art, be characterized in: it comprises the ruler 1 that has the length scale and the circular protractor 2 of angle index, circular protractor 2 is fixed on the hollow shaft 5, the setting-out notch 6 of circular protractor 2 communicates with the setting-out notch 10 of hollow shaft 5, and ruler 1 is placed on the hollow shaft 2.
On ruler 1, be nested with slide block 3, on slide block 3, be provided with setting-out hole 4 and tuning drive gear hole 9.
Head end at ruler 1 is provided with indication point 7.
The combination ruler of using of the present utility model owing to adopt ruler and protractor and slide block combination, can be realized setting-out section or slotted line segment length more; Can draw angle or take measurement of an angle; Can draw circle or arc.Can also fasten at rectangular co-ordinate and get a mapping; Also can on polar coordinate system, get a mapping.Head end at ruler also is provided with the indication point, can be used as teacher's pointer and uses.It is many to have function, easy to use, scope is wide, advantage such as draws, measuring speed is fast.
The utility model is described in further detail to utilize drawings and Examples below.
How Fig. 1 is for looking schematic diagram with combination ruler structure master.
Fig. 2 is an A-A cross-sectional schematic among Fig. 1.
Fig. 3 is a B-B cross-sectional schematic among Fig. 1.
Fig. 4 looks schematic diagram for circular angle gage structure master.
With reference to Fig. 1-4, how all to make the also available plastic production of ruler 1, circular protractor 2 and slide block 3 of stainless steel with ruler 1, circular protractor 2, slide block 3, holding screw 11 and the location screw 8 of combination ruler.Ruler 1 is provided with the length scale, and the head end of one end is provided with indication point 7.Circular protractor 2 is provided with angle index, and the place is provided with setting-out notch 6 at the zero degree groove.Setting-out notch 10 also is set on the hollow shaft 5.Circular protractor 2 is fixed on the hollow shaft 5, and ruler 1 is placed on the hollow shaft 5, the setting-out notch 6 of circular protractor 2 is communicated, so that begin picture from centre point when setting-out with setting-out notch 10 levels of hollow shaft 5.With reference to Fig. 1 and 3, on ruler 1, be nested with slide block 3, on slide block 3, be provided with setting-out hole 4, tuning drive gear hole 9 and holding screw 11.The dog screw 8 that limits slide block 3 greatest limit positions is set on ruler 1.
During the setting-out section, the zero degree line of circular protractor 2 overlaps with the setting-out sideline of ruler 1, and paintbrush is ended from hollow axle center 5 through the scale of setting-out groove 10,6 to ruler.
When drawing circle or arc, be the center of circle, paintbrush is packed in the setting-out hole 4 of slide block 3 with hollow shaft 5, slide block 3 is fixed on the ruler 1, the radial location of tuning drive gear hole 9 indication circles or arc is rotated ruler 1 again around hollow shaft 5, stop getting final product in the respective angles scale position of circular protractor 2.
Draw angle or when taking measurement of an angle, the zero degree line of circular protractor 2 is overlapped with the setting-out sideline of ruler 1, the setting-out section is that the center of circle rotates ruler 1 with hollow shaft 5 again, the setting-out sideline of ruler 1 is overlapped with the scale position of circular protractor 2 get final product.
When drawing times angle, angular bisector, five equilibrium circular arc, vertical angle, measure earlier and calculate setting-out again, the angle technique of painting is identical with drawing.
Also can get a mapping in rectangular coordinate system, polar coordinate system.Fasten at rectangular co-ordinate and to get a little, measure y axial coordinate point position with ruler 1, the hollow shaft 5 of circular protractor 2 is placed y axial coordinate point position, rotate circular protractor 2, its zero degree groove is overlapped with y axial coordinate point, rotate ruler 1 again, making ruler 1 graduation mark is 90 °, then ruler 1 perpendicular to the y axle, be parallel to the x axle, then the indication point of ruler 1 is exactly the set point that rectangular co-ordinate is fastened.Get on polar coordinate system a little, principle is identical with rectangular coordinate system.
