The utility model discloses beneficial effect: simple structure, reasonable in design can realize not moving the quick accuracy of the movable auxiliary scale coordinate system cross axle vertical axis that draws up to mark the scale in the setting -out, from taking the empty eyespot battle array of complete set, can mark out coordinate system integral point coordinate fast, multiple geometric figure makes, and the mapping is accurate quick, saves time.

Description

A kind of coordinate system student's square chi for carrying groove type scale and complete set dot matrix

Technical field

The utility model is related to Students ' Learning field of stationery, and specifically one kind carries groove type scale and complete set dot matrix Coordinate system student's square chi.

Background technology

Current student draws coordinate system mapping, is all to compare 90 ° with ruler respectively to draw once anyhow, then further each and every one marks by hand Go out scale, waste time and energy, waste the quality time；During analytic geometry study, the either direct proportion function in junior middle school, inverse ratio Example function or the exponential function of senior middle school, logarithmic function, power function and trigonometric function, are mapped with trace-point method, need one Each and every one described point, it is very inconvenient, waste time and energy, and also common ruler described point is drawn many times less accurately, for solving a problem just Really property affects larger while the time of middle school student is very valuable, and when especially taking an examination, the time is even more important, therefore, it is possible to accurate Quickly draw and be just particularly important, therefore effectively drawing tool just seems precious.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of coordinate for carrying groove type scale and complete set dot matrix It is student's square chi, solves the problems, such as current middle school student's mapping.

The utility model is that the technical scheme that solution above-mentioned technical problem is adopted is：One kind carries groove type scale and complete Coordinate system student's square chi of mooring points battle array, the square chi is integrated shape, including transparent square chi body, along the side of square chi body surrounding Edge is provided with length scale, is uniformly provided with the distance between multiple through holes, two neighboring through hole in square chi body surface and is 5mm, Two orthogonal hollow recess for picture coordinate system are opened up at the center of square chi body, in the side of the side of hollow recess The edge of chi body uniformly opens up multiple V-grooves, is provided with two diameters as the center of circle with the intersection point of two hollow recess identical and right The protractor of title, in the circumference of protractor angle index is provided with.

The distance between two neighboring V-groove described in the utility model is 5mm.

The radius of through hole described in the utility model is 0.5mm ~ 1.5mm.

Various Conventional mathematical patterns are provided with the upper surface of described square chi body.

Regular pattern described in the utility model is direct proportion function, linear function, inverse proportion function, exponential function, right Number function, power function, sine curve, cosine curve, quadratic function, square, cuboid, cylinder and prism.

Square chi body described in the utility model is made up of plastics or glass.

The beneficial effects of the utility model are：The utility model simple structure, it is reasonable in design, with advantages below：1. The square chi that utility model is provided can realize that not moving ruler quick and precisely draws coordinate system transverse axis vertical pivot, and while setting-out Scale is marked, is killed two birds with one stone, mapping is accurately quick, time-consuming；2. square chi of the present utility model carries complete set sky eyespot battle array, can Coordinate system integral point coordinate is quickly marked, convenient and swift accurate mapping is realized；3. the empty eyespot battle array of the utility model square chi can appoint Meaning combination, picture triangle, parallelogram, rectangle, square, prism, pyramid, cylinder, circular cone etc. are all very convenient quick, mark Draw by going out summit, the big I of figure is arbitrarily adjusted, and can to a great extent shorten the mathematic(al) construction time of middle school student；4th, originally The chi of utility model one is multiplex, and a chi is general, from the junior one to high by three, from plane geometry to analytic geometry, solid geometry, from polyhedron To rotary body, from trigonometric function to conic section, add a compasses again using new square chi using this, you can with quick and precisely Make various figures.
