Description
Technical field
The present invention relates to a kind of multi-function drawing instrument, belong to geometric figure drawing tool field, specifically a kind of multifunctional drawing instrument.
Background technology
In the teaching of school mathematics geometric figure, university's mechanical drawing teaching and study and many Practical Project drawing courses, usually use the single drawing instruments such as set square, compasses, T-square and ruler, during a geometric figure of concrete drafting, these several tool combinations are used, have the basic point positional accuracy, the problems such as slippage appear in the drawing process instrument, thereby make the graphical quality of drafting and draftsman's qualification have the very large degree of association, make simple graphing process become repetition, complicated dull process.
Some combination drawing tools occur at present, for example CN202319571U discloses a kind of multi-functional ruler-compasses.This ruler is provided with annular outer ring, fixed cross beam, rotation chi, the inboard center line of annular outer ring arranges fixed cross beam, form two symmetrical semicircle frames between fixed cross beam and the annular outer ring, the fixed cross beam center drilling, the rotation chi is arranged at the annular outer ring inboard, rotation chi centre bore, fixed cross beam centre bore connect by central shaft, have the angle groove at annular outer ring.Can draw straight line, circle, circular arc, annulus and arbitrarily angled etc.The disclosed multi-functional ruler-compasses of CN201566332U comprises the right angled triangle substrate, comprises the right angled triangle substrate, just can draw various figures with a drawing tool.These combination drawing tools, although having improved a plurality of single drawing instruments exists not Portable belt, easily the problem such as loses, but having a problem is exactly to draw basic " single " figure, still there is the problem such as basic point positional accuracy and slippage in the drawing process in drafting for composite figure, does not satisfy the actual drawing needs of engineering.
Summary of the invention
Single in order to overcome existing drawing instrument, there are in the graphic plotting process deficiencies such as the inaccurate and instrument slippage in basic point location, the present invention proposes a kind of multi-function drawing instrument.
The present invention is comprised of the warp chi of substrate, string of a musical instrument chi and two different lengths; It is characterized in that described substrate is annular, two-layer about being divided into, lower floor arranges the circular chute of twice, two warp chis are installed respectively, the upper strata arranges two arcuate sockets, and string of a musical instrument chi is installed, and indicates uniform 0-360 ° angle value and groove thereof on the internal diameter circumference of upper strata; Described string of a musical instrument chi is straight plate shape, and the centre is provided with chute, and two straight lines of string of a musical instrument chi and two straight lines of chute are provided with length value and the groove thereof of the direction of going forward one by one on the contrary; Described warp chi is straight plate shape, and the centre is provided with chute, and two straight lines of warp chi and two straight lines of chute are provided with length value and the groove thereof of the direction of going forward one by one on the contrary.
The technical solution adopted for the present invention to solve the technical problems is: with the substrate horizontal positioned, its inner circular shaped region is for the district that draws, with the figure basic point of the center of circle as required drafting.The warp chi of two different lengths links with centrepin at substrate home position place, can realize 0-360 ° of direction rotation; Wherein shorter warp chi (warp chi 2) is installed in the below, and supports with locknut, and it is horizontal; Shorter warp chi (the warp chi 2) other end is installed in the chute 2 of substrate lower floor by slide block 2.Long warp chi (warp chi 1) is installed in shorter warp chi 2 tops, and its other end is installed in the chute 1 of substrate lower floor by slide block 1.Can be according to the residing position of the lines of figure (or basic point) and direction during drawing, mobile two warp chis, draw the line segment of different angles, if need to draw camber line, then take a certain position of a warp chi as the camber line starting point, in the middle chute of another warp chi, behind the location, rotate this warp chi and just can finish.String of a musical instrument chi is installed in the substrate top, the one end links by the arcuate socket 1 of alignment pin 1 with the substrate top, the other end links by alignment pin 2 another arcuate socket (arcuate socket 2) with the substrate top, two alignment pins can move in the chute and in two arcuate sockets on substrate upper strata in the middle of string of a musical instrument chi respectively along with the movement of string of a musical instrument chi, can realize the rotation of 0-180 ° of direction of two symmetries.Behind the cardinal point determination of required graphing, draw with basic point straight line at regular intervals, can be in two arcuate sockets of substrate mobile string of a musical instrument chi, realize that the straight line of any angular orientation is drawn.
The invention has the beneficial effects as follows: can realize required graphing is carried out one-time positioning the inaccurate problem of basic point unit of avoiding single drawing instrument to occur by substrate center's pin; At any angle lines and camber line can be drawn by two the warp chis that slide, the drafting of lines on any direction with the basic point certain distance can be realized by string of a musical instrument chi.Compact conformation of the present invention is easy to carry, and has the drafting that realizes simple graph and complex figure and the characteristics that need not change basic point namely has the functions such as angle, size and direction, and is practical.
