Abstract
The utility model relates to a multifunctional drawing instrument, composed of a straightedge, a positioning apparatus, a line-drawing apparatus and an ellipsograph. The positioning apparatus and the line-drawing apparatus are arranged at both ends of the straightedge. The line-drawing apparatus can freely slide along a straightedge groove. The ellipsograph is used for drawing ellipses and parabolas. Integrated with the functions of a straightedge, compasses, a set-square, a protractor and an ellipsograph, and overcoming the defects of the drawing tools, the utility model has economy, practicality and a cost lower than the normal compasses.
Description
The utility model relates to a kind of drawing instrument, particularly a kind of multi-function drawing instrument.
At present, drawing instruments such as widely used ruler, compasses, protractor, set square more and more seem dull owing to the needs of high-speed plotting, lack comprehensive function, and many inconvenience are in use arranged.As ruler retouch, the drawing of easily prepared Chinese ink being made dirty along the edge when drawing; Garden rule are easily exposed paper, the change of the garden heart; Protractor is felt relieved, is looked for angular speed slow; The drawn angle of set square very little, ellipsograph is not still popularized etc.Be badly in need of a kind of can with the function of common drawing instrument molten be one, easy to use, economic comprehensively multifunctional drawing tool.
The utility model is a kind of multi-function drawing instrument for the above-mentioned shortcoming design that solves common drawing instrument.This plotter with the function of ruler, compasses, protractor, set square and ellipsograph molten be one, except drawing arbitrary line, circle, circular arc, ellipse, angle and hyp most line segment (not in its ruler scope) by direct reading, can also overcome the shortcoming of above-mentioned drawing instrument.
Technical solution of the present utility model and operation principle are: two points make a line; Fixed length rotates a circle into a circle around fixed point; Moving point to two fix a point do not become an ellipse apart from sum; Draw two straight lines by any and become one jiao; The difference of moving o'clock to 2 o'clock distance does not become double curve.According to above-mentioned reason, load onto locator and scriber at ruler two ends of being carved with various scales, pilot hole and groove, when needing ellipse garden of picture and parabola, refill oval device, can finish all work that above-mentioned various drawing instrument can be finished.
The utility model is compared with existing drawing instrument, and it is multiple functional, economical convenient to have, and can overcome the shortcoming of above drawing instrument, and cost is lower than common compasses, and is economical and practical.As its structure is transplanted on the draught machine, can simplifies its structure greatly, increase plotting speed, and reduce its cost.
Below with reference to accompanying drawing the utility model is done further detailed description.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the organigram of ruler.
Fig. 3 is the structural representation of ellipse garden device.
Fig. 4 is the vertical view of oval device.
Number in the figure is represented:

Referring to Fig. 1, load onto locator at the left end of ruler (2), right-hand member dress scriber, the centre is oval device.Scriber can be free to slide on ruler, and oval device is connected with scriber and can be free to slide with the locator at two ends with line.Ruler (2) has various scales, pilot hole and groove.Locator is made up of base (1), angle scale (3), locator moving runner (4), centering pin (5) and pressure cap (6), base (1) below ruler (2) with centering pin (5) with being threaded.Angle scale (3) and locator moving runner (4) are inserted in centering pin (5), are loaded on the ruler (2), adopt interference fit, on adorn pressure cap (6).Scriber is made up of bracket (13), clamp nut (15), size mark (14), scriber moving runner (12), the plumbous cover of scriber dress (11), spring (10), lead for retractable pencil (9) and lead extrusion cap (8).Bracket (13) is loaded on below the ruler (2) and the scriber plumbous cover of dress (11) assembles with screw thread.Size mark (14), clamp nut (15) and scriber moving runner (12) all are contained on the ruler (2), and be fixing with the scriber plumbous cover of dress (11), and lead extrusion cap (8) is loaded on the scriber plumbous cover of dress (11) with screw thread.Ellipse garden device is made up of base (17), locking pin (16), top box (19), nowel (18), line tube (20), the ellipse garden device plumbous cover of dress (21), lead extrusion cap (22).Base (17), top box (19), nowel (18), line tube (20) are all fixing with the ellipse garden device plumbous cover of dress (21).Line tube (20) is loaded on the inside of top box (19) and nowel (18), and lead extrusion cap (22) connects ellipse garden device with locator moving runner (4) and scriber moving runner (12).
When using, its scriber is moved along straight flute, or form with moving in addition along its ruler limit as ruler.
When using as garden rule, mobile scriber by the fixed length half of size mark (14) indication through scale, locking clamp nut (15), according to pressure cap (6) again turn ruler (2) can become round.If the picture arc then rotates to and decides angle and get final product.
When drawing ellipse, focal length is reserved on ruler (2), then, reserved line length by its distance, circle is gone up scriber moving runner (12) again, tensioned thread moves ellipse garden device and promptly is drawn as ellipse garden.
When drawing angle, reserved a little by locator earlier, the groove along ruler (2) moves the start line that scriber is done the angle then, spin-up lead for retractable pencil (9), rotation ruler (2), the center line of ruler (2) stops when aliging with angle line, screw off lead for retractable pencil (9), oppositely draw back along straight flute.Promptly angled.
When doing the part hyperbola, the locking pin (16) in the device of ellipse garden is pulled up.Then, read its focal length (focal length is a locator), on straight line, find out its summit, begin from the summit to move ellipse garden device, can draw hyperbola with the scale of ruler (2).
