Abstract
The utility model discloses a multifunctional graphic plotter, comprising a ruler, a protractor and a connecting shaft. The ruler consists of a main ruler and an auxiliary ruler, the centre lines of the main ruler and an auxiliary ruler are respectively provided with an open slot. A protractor is arranged between the main ruler and the auxiliary ruler. A slipper is arranged on the open slot. The slipper, the main ruler, the protractor and the auxiliary ruler are integrated by the connecting shaft. The utility model is simply combined by two rulers and a protractor, which can complete to draw parallel, quadrangle, arbitrary included angle, arbitrary radian and arbitrary polygon.
Description
The utility model relates to instrument of surveying and mapping, specifically belongs to drawing instrument.
In industrial production, architectural design and Mathematical Experiments, one of the work that is absolutely necessary of charting of drawing.People must can finish the work preferably by drawing instrument when drawing drawing.Drawing instrument commonly used at present has ruler, set square, protractor, compasses or the like, and these drawing instruments all are scattered, and are indispensable when drafting has the figure of multiple geometry.Thereby people are when drawing, must be all on deck with all instruments, otherwise, will bring very big inconvenience.In addition, usually need also when drawing to realize after a plurality of tool combinations identical or inequality that for example drawing parallel lines needs two set square combinations to carry out, and draws one section camber line, must have compasses and protractor to cooperate with these scattered instruments.Use these traditional instruments to draw, promptly lose time, lack the degree of accuracy again.
The purpose of this utility model just provides a kind of drawing instrument that is combined into one, and it is simple in structure, easy to use, can be suitable for drawing simultaneously simultaneously multiple geometric figure again.
The purpose of this utility model is to realize like this, designed multi-function drawing instrument, include ruler, protractor and coupking shaft, its ruler is made up of main scale and auxilliary chi, centerline at main scale and auxilliary chi is respectively arranged with open slot, accompany protractor between main scale and the auxilliary chi, the open slot of main scale and auxilliary chi is provided with slide block, and slide block, main scale, protractor, auxilliary chi combine as a whole by coupking shaft.
The utility model carries out simple combination by two rulers and a protractor, can finish any parallel lines, quadrangle, angle, the drafting of radian, arbitrary polygon arbitrarily arbitrarily.
Be described in further detail the utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
As shown in Figure 1, the utility model mainly is made of ruler, protractor, and ruler is made up of main scale 1 and auxilliary chi 2, and the structure of main scale 1 and auxilliary chi 2 is basic identical, all is provided with open slot 5 in the centerline of main scale 1 and auxilliary chi 2.Accompany protractor 12 between main scale 1 and the auxilliary chi 2, the string of protractor 12 parallels with main scale 1 graduated limit, on the open slot 5 of main scale 1 and auxilliary chi 2, be provided with slide block 6, slide block 6, main scale 1, protractor 12, auxilliary chi 2 are by a coupking shaft 11, it is coupled as one, when main scale 1 is fixed when motionless, auxilliary chi 2 slides along the open slot on the main scale 15 with slide block 6, a plurality of parallel lines can draw, rotate auxilliary chi 2 with coupking shaft 11, can the throughput hornwork 12 shown angles, the corner of the different angles of drawing.When the angle is fixed, the limit then can be drawn arbitrary polygon fixedly the time.Plotter is smooth to be suitable in order to make, and preferably the periphery of the open slot 5 in main scale 1 and the auxilliary chi 2 is established to be inclined-plane 13, and slide block 6 can fit tightly with the periphery of open slot 5 like this, has avoided it unevenly to make troubles to drawing.Drive a tiny open slot 8 again in main scale 1 a graduated side, on this open slot 8, fix a slide plate movably with holes 9, when main scale 1 rotates with coupking shaft 11, nib is inserted in the slide plate with holes 9 camber line of can draw different radians and different radii like this.On the coupking shaft 11 that connects main scale 1, auxilliary chi 2 and protractor 12, preferably fix a pointer 10, the direction indication of this pointer 10 is corresponding with the scale limit on the protractor, like this, the reading of the angles of display of being more convenient for.Preferably be provided with the fixing card 4 of slide block on the open slot 5 at the back side of assisting chi 2, when fixing card 4 blocked slide block 6,2 of main scale 1 and auxilliary chis were in the relative fixed state.When making that pointer 10 is parallel with the scale limit of auxilliary chi 2, the string of protractor 12 is parallel with the scale limit of main scale 1, main scale 1 and auxilliary chi 2 have the angle on scale limit just to equal the angle of pointer indication like this, just main scale, auxilliary chi have the angle on scale limit to the angle of known thus string and pointer as can be known, thereby the angle that can both draw the different number of degrees can be used for measuring the number of degrees of a certain angle again.A magnetic stripe 7 is preferably established in front at main scale 1 again, corresponding with it of auxilliary chi 2 an iron metal wire 3 is set, and so more helps main scale and auxilliary chi fixing under certain state.
The utility model is simple in structure, easy to use, and it can draw out various geometric figures simultaneously, has solved scattered plotter and has carried inconvenience, uses cumbersome problem.
