Abstract

The utility model relates to a square and round rule gauge which is a drawing instrument integrated by multiple functions which are known by publicly, wherein, the gauge is provided with hollow graphics such as circle, ellipse, lozenge, regular pentagon, regular hexagon, etc. by marking a scale of a ruler and a protractor; the gauge is provided with an amplifier and a compass tip, a steady position card, a 'drawing board ' (6) which is provided with screw nut connecting holes, and 'ruler' (1) which is used for drawing lines is provided with slide channels arranged in equal distances and magnetic take-up device; the amplifier, the compass tip, the steady position card, the 'drawing board ' (6), and the 'ruler' (1) are connected to integration by screw nuts. Drawers can draw various geometrical figures without taking other instruments to match. The functions are realized mainly by the mutual perpendicular or mutual movement kept by the 'ruler' (1) and the 'drawing board '(6), under the control of a screw nut (11) and the steady position card (7).

Description

Square and round rule gauge

The utility model belongs to a kind of drawing instrument.

For a long time, people often use compasses, protractor, ruler, set square in drawing, drawing board is drawn or measure circle, angle, triangle, polygonal figures.In many cases, draw or measure some figure, need two or more instrument cooperation just can finish, this just brings all inconvenience to the illustrator.Prior art is referring to the patent application in our on December 29th, 90, please number be 90227097,4 wherein, and name is called " multifunctional compass ".

The purpose of this utility model, provide a kind of plotter that integrates repertoires such as ruler, set square, drawing board, protractor, amplifier, compasses, ellipsograph, slide measure, angle square, T-square, engineer's scale, parallel rule, Equant ruler, coordinatograph, level meter, make the designer not need other any instrument to cooperate, just can draw or measure arbitrary graphic, drawing, make easier, the science more of drawing.

The purpose of this utility model is achieved like this.Indicate chi and protractor scale with one, have hollow figures such as circle, ellipse, prismatic, positive five square, regular hexagon, be provided with magnifying glass, the compasses tiptoe, steady position card, " drawing board " of nut connecting hole and " chi " that has equidistant chute, is provided with magnetic take-up and setting-out pin couple together with nut.Its " chi " can keep orthogonal and mutual motion with " drawing board " under the control of nut and steady position card.Construct as shown in Figure 1:

Fig. 1: be the structural representation of Square and round rule gauge.

Among Fig. 1: (1), for having equidistant chute is provided with " chi " of magnetic take-up and setting-out pin.

(2), be magnetic take-up on " chi ".

(3), be setting-out pin on " chi ".

(4), be the opposite direction scale on " chi " (so that directly measuring half round warp, oval focal length etc.).

(5), be through wires hole on " chi ".

(6), for indicating chi and protractor scale and having multiple hollow geometric figure, be provided with " drawing board " of amplifier, steady position card.

(7), be steady position card on " drawing board ".

(8), be amplifier on " drawing board ".

(9), be multiple hollow geometric figure on " drawing board ".

(10), be chi on " drawing board " and protractor scale (scale of chi makes progress respectively, rises so that the coordinate mapping to subscript).。

(11), be that " drawing board " goes up the nut of installing (this nut is on the heart point of protractor).

(12), be compasses tiptoe on " drawing board ".

In Fig. 1.Setting-out pin (3) should with " drawing board " (6) at grade, so setting-out pin (3) is the thickest position in " chi ".

Make any geometric figure with this ruler, can both reach not only fast but also effect accurately.

Fig. 2-Fig. 3 gives an example for mapping.

Fig. 2, by being made equality line, five equilibrium line segment, rectangular co-ordinate etc.

Fig. 3, round arbitrarily by being done.

The using method that the utility model is the most general: be to push down with the right hand to have equidistant chute, be provided with the right-hand member of " chi " (1) of magnetic take-up and setting-out pin, left hand is parallel to move through steady position card (7), nut (11) connect indicate chi and protractor scale and have multiple hollow geometric figure, be provided with amplifier and steady position card " drawing board;, (6).Just can make parallel lines, rectangular co-ordinate, geometric figure such as five equilibrium line segment or determine half round warp, oval focal length etc.Three groups of geometric figures that Fig. 2 has done from right to left are exactly parallel lines, rectangular co-ordinate, five equilibrium line segment.The circle that Fig. 3 has done, being exactly to be aligned in position on " chi " (1) by compasses tiptoe (12), is half warp of this circle.

Claims

1. Square and round rule gauge, it is characterized in that: one is indicated chi and protractor scale, has multiple hollow geometric figure, is provided with " drawing board " and " chi " that has equidistant chute, magnetic take-up and setting-out pin are housed of steady position card and compasses tiptoe, couple together with nut, make its orthogonal and mutual motion.
