Abstract
The utility model relates to a universal ruler, which is characterized in that a pulley wheel is arranged on a ruler plate, and the axial direction of the pulley wheel is parallel to the long edge of the ruler plate. Length graduations are marked on the long edge, and the central position is marked with graduation of a protractor. A centre point of the protractor is overlapped with the center point of the long edge, and a fulcrum is arranged at the center of the circle. The O line of the protractor is parallel to the long edge, and fixing holes are uniformly distributed on the extension line. A row of parallel correction lines which are perpendicular to the long edge are marked on the ruler plate. The universal ruler collects the traditional drawing tools, such as a set square the protractor, compasses, etc. to integration, and can be used for drawing parallel lines, vertical lines, angle lines, circles, etc.
Description
The utility model belongs to the stationery field, particularly a kind of multiduty isograph.
Will the mathematics template function in existing stationery rule more complete, it integrates ruler, protractor and geometric templates.The structure of template is to depict the length groove on the long limit of flat board mostly, and a minor face is used to carve the scale of protractor, in dull and stereotyped other parts hollow out various how much nibs or curved slot is arranged.Comparatively convenient but weak point is also arranged when template is used, it can not be used to paint parallel lines or circle separately.
The purpose of this utility model is a kind of isograph of painting parallel lines, vertical line, angle line and circle that integrates of design.
Task of the present utility model is to realize like this, a pulley chamber arranged in that a side plane of chi plate is convex, be provided with draw-in groove in the chamber, block the pulley axle sleeve, be fixed with pulley on the axle, the wheel of pulley is along another plane of slightly protruding the chi plate, axle parallels with a long limit of chi plate at least, and delineation has the length groove on this long limit, and delineation has a protractor scale in the center, the centre point of protractor is overlapping with the central point on long limit, and establish a fulcrum in the center of circle, protractor O line is parallel with long limit, evenly is laid with fixing hole on its extension line, also delineation has one to arrange the compensation line that parallels on the chi plate, and compensation line is perpendicular with long limit.During use, gently move the chi plate, it is preceding or mobile backward that the chi plate can only be lived by the restriction of pulley, and can draw out row parallel lines along the long limit of chi plate this moment; Penholder is gone into fixing hole, the attachable mechanical stage plate can be drawn and the perpendicular line of above-mentioned parallel lines then, and utilizes compensation line and all the other fixing holes on the chi plate, can draw the vertical line of various different spacing, utilize (chi plate) fixing hole to rotate and to draw circle around fulcrum.
The utility model is simple in structure, and is easy to use, can be used for substituting traditional drawing instruments such as set square, protractor and compasses, and can be made into gently, thin, little, is easy to carry, and the personage who is particularly suitable for students in middle and primary schools and draws simple table uses.
Below in conjunction with concrete legend the utility model is described further:
Accompanying drawing isograph schematic diagram
With reference to a side plane of the chi plate 1 of accompanying drawing isograph is convex a pulley chamber 2 arranged, be provided with draw-in groove 3 in the chamber, be used to block pulley axle sleeve 4, location pulley spindle 5, make axle 5 keep paralleling with a long limit of chi plate 1, the chi plate 1 of this legend is a rectangle, also promptly axle 5 is all parallel with two long limits, and all can delineate length groove 6 this moment on long limit and minor face, be convenient to multi-faceted use, in the delineation of the center on a long limit one protractor scale 7 is arranged, the centre point of protractor is overlapping with the central point on long limit, establishes a fulcrum 8 in the center of circle, makes center of circle fulcrum usefulness as painting bowlder, protractor O line 9 is parallel with long limit, evenly be laid with fixing hole 10 on its extension line, be used for draw circles or vertical line usefulness, and also can lay this type of fixing hole 10 on other limit, also delineation has one to arrange the compensation line 11 that parallels on chi plate 1, and compensation line 11 is perpendicular with long limit.Two ends at axle 5 respectively are fixed with pulley 12, the direction that guarantees chi plate forward-reverse is constant, the wheel of pulley 12 is along another plane of slightly protruding chi plate 1, pulley 12 is taken turns to be had graduation mark 13, the center line of pulley chamber 2 corresponding pulley 12 orthographic projections to be provided with an index line 14 along delineation to cooperate the displacement of promptly knowing the chi plate with graduation mark 13 on the pulley.But hollow out has various geometric figure nibs 15 and other curve plate hole on chi plate 1.The section of fulcrum 8 is an I shape, is stuck in the circular hole 16 of chi plate 1, and the bottom of circular hole 16 is bigger, but in the fulcrum 8 indentation circular holes 16, not limited by fulcrum when drawing beeline etc. is mobile like this.
Claims (4)
1, a kind of isograph, it is characterized in that a side plane of chi plate is convex has a pulley chamber, be provided with draw-in groove in the chamber, block the pulley axle sleeve, be fixed with pulley on the axle, the wheel of pulley is along another plane of slightly protruding the chi plate, axle parallels with a long limit of chi plate at least, and delineation has the length groove on this long limit, and delineation has a protractor scale in the center, the centre point of protractor is overlapping with the central point on long limit, establish a fulcrum in the center of circle, and protractor O line is parallel with long limit, evenly is laid with fixing hole on its extension line, also delineation has one to arrange the compensation line that parallels on the chi plate, and compensation line is perpendicular with long limit.
