Abstract

The utility model relates to a multipurpose drawing instrument which is composed of a bottom seat and a rotating disc. The rotating disc is provided with a groove for lining along diameter. Both sides of the groove for lining are provided with scale marks and a hole for drawing an arc and a circle. A circular ring of the bottom seat is scaled with a 360 DEG graduation line. The utility model is characterized in that the inner side of the groove for lining is provided with a slide way on which a slidable pen frame is arranged, and the pen frame is provided with a refill. The utility model forms such traditional drawing tools as a compasses, a protractor, a setsquare, a ruler, etc. into integration and combines the functions thereof in one. The utility model has the advantages of unique structure, ingenious combination, a multifunctional tool, convenience for drawing the circle, an angle, the arc, a line, a polygon and for measuring an angle, optional regulation of the diameter, rapidity and convenience.

Description

Multipurpose plotter

(1) technical field: the utility model belongs to stationery, is specifically related to a kind of multipurpose plotter for teacher, student and engineers and technicians' use.

(2) background technology: by my invention, the patent No. is 01252679.7 " multi-functional latent heart compasses ", mainly is made of base and disk, gathers multi-function in integral whole, and has solved the problem that the bowlder circle centre position leaves pin hole of drawing; But find that in use its function is perfect not enough, when being mainly reflected in the longer line segment of picture length inadequate slightly and when drawing circle picture arc radius regulate not really random.

(3) summary of the invention: the purpose of this utility model is exactly further perfect to the structure of multi-functional latent heart compasses, proposes a kind of multipurpose plotter that can draw longer line segment and energy regulated at will picture circle picture arc radius.

This multipurpose plotter has base and rotating disc, and rotating disc is provided with marking groove along diameter, and there is graduation mark on the marking groove both sides and draws arc and draw circular hole; Be carved with 360 ° of reticules on the annulus of described base, described marking groove inboard is provided with slideway, and slidably penholder is housed on it, and pen core is housed on the penholder;

Described penholder bottom has slide, and front end has last lower fixed frame, and through hole is arranged on the fixed mount, is respectively arranged with spring and pen clip pawl in the fixed mount.

Described base reaches triangle or the polygon chi rabbeted with the annulus outer rim by annulus and constitutes.

Be respectively arranged with square card painting hole and circular hole on described triangle or the polygon.

Described rotating disc can be processed into cross, hexagon or circle.

After improving, the utility model also has following characteristics except that the function that keeps existing multi-functional latent heart compasses:

(1) utilize triangle or polygon on the base can draw longer line segment, increased and strengthened the function and the purposes of ruler, utilization is simultaneously scribbled the answering card aperture and is scribbled answering card with can making things convenient for standard.

(2) on marking groove, increased the penholder device, can regulate picture circle picture arc radius easily, and penholder pen clip change-fountain pen has been convenient, the lifting nature.

(4) description of drawings:

Fig. 1 is the structural representation of an embodiment of the utility model;

Fig. 2 is the structural representation of penholder among Fig. 1.

(5) specific embodiment:

Referring to Fig. 1, this multipurpose plotter comprises base 1, this base comprise annulus 1 ' and with the triangle chi 1 of this annulus outer rim interlocking "; The annulus inboard has groove, is criss-cross rotating disc 2 edges and has projection, and embed just in the above-mentioned groove, and is light one group with have gentle hands, can rotate freely in annulus.This rotating disc is provided with marking groove 3 along diameter, and there is graduation mark 4 on the marking groove both sides and draws arc and draw circular hole 5; Be carved with 360 ° of reticules 6 on the base annulus, be provided with slideway, the penholder 7 that can slidably reciprocate along this slideway is housed on it, pen core 8 is housed on the penholder in the marking groove inboard.Described penholder bottom has slide 9, and referring to Fig. 2, front end has fixed mount 10, through hole is arranged on the fixed mount, be respectively arranged with spring 11 and pen clip pawl 12 in the fixed mount, the pen core and the pen cap 13 insert in described spring and the pen clip pawl along the through hole on the fixed mount, and stretch out marking groove and draw circle usefulness for the picture arc.Above-mentioned pen core is conversion such as pencil, pen or chalk etc. as required, the triangle of base is provided with card painting hole 14 and small sircle hole 15, also is provided with dial hole 16 at rotating disc one end, draws bowlder, the arm of force in the time of can rotating to increase rotating disc by this dial hole plays the labour-saving effect.

Triangle chi in the utility model can be replaced by the polygon chi, the cross of rotating disc in present embodiment, also can be designed to circle, hexagon etc., and penholder also can be made into various ways such as spiral and rack-and-pinion.

During use, this plotter is placed by picture thing surface, pin base edge,, can adorn sucker, magnet etc. in base back surface as the heavy caliber plotter of teaching usefulness with hand; Can be decorated with heart circle easily, have the inclination arc, latent heart circle, latent heart arc, once can draw a plurality of concentric circles, arc, radius penholder regulated at will is drawn angle, angulation, setting-out section, picture polygon, sets up all geometric figures such as rectangular co-ordinate.
