Description
Technical field
The utility model relates to a kind of study, drawing instrument of how much subjects, is specifically related to the set square with calipers angle measurement device.
Background technology
Students in middle and primary schools learn how much subjects and general engineering technology personnel while drawing, all want use amount hornwork, compasses, ruler, four drawing instruments of set square, yet these four study, drawing instrument, due to not science, unreasonable, not rigorous being set himself, function singleness, brings a lot of inconvenience, in actual use as compasses separately, draw bowlder not by ruler, do not know the accurate radius of self drawn circle; While drawing arc, not by ruler protractor, do not know accurate radius and the number of degrees of drawn arc.Protractor also can only not by compasses-ruler, can not be made two limits at the angle of random length for angulation, more can not draw arc; And ruler set square both can only measure length, can not be for angulation, draw circle; All these reasons, cause in actual use, need to cooperatively interact, and repeatedly change, and just can complete graphic making, and in changing frequently drawing instrument process, the error while easily causing point, line to connect; For study, can not intuitively, intactly explain out the real meaning of some concept; When study and drawing, often need ruler, compasses, protractor, four instruments of set square to be used in conjunction with each other, just can complete graphic making, give to carry and make troubles.
Publication number is that the Chinese patent of CN2286677Y discloses a kind of Angle gauge ruler drawing board, on the straight line of the exterior deckle board of described drawing board, be carved with ruler scale, it is characterized in that, there is a larger circular hole in the central authorities of exterior deckle board, in this circular hole, there is a rotating circular disk identical with its radius and that coordinate with it, the circumference of rotating circular disk is carved with the angle measuring calibration of 0 °-60 °, exterior deckle board central circular hole within one week, be also carved with angle measuring calibration, on rotating circular disk and exterior deckle board, be drilled with respectively from rotating circular disk distance of center circle from pen plughole not etc.; On the inner periphery of exterior deckle board central circular hole, having a circle thickness is the platform of 1/2 exterior deckle board thickness, the convex edge that has a circle to match with platform on the circumference of rotating circular disk.
This Angle gauge ruler drawing board, because it adopts housing sleeve-board one roundel for drawing circle, when drawing the less bowlder of radius, due to centrifugal action, is difficult to draw the circle that radius is less.And make the bowlder that radius is larger, the angle gauge use that turns over, very inconvenient again; Its design adopts exterior deckle board to embed roundel in addition, and angle index that roundel is marked is positive and negative two covers, while doing angle, easily obscures, and easily makes mistakes.Moreover its roundel thickness is identical with exterior deckle board thickness, roundlet rotation platform is identical with exterior deckle board rotation platform thickness, draws bowlder and is easy to skid off, poor practicability.
