Abstract

The utility model discloses a square gauge, consisting of a biangular goniometer, a rotary ruler, a circle drawing ruler, a lace calipers, a fixing screw sleeve, a built-in needle screw sleeve and a helix take-up lock. The utility model is characterized in that completes various geometric figures through the different combination of the four rulers; in particular, draws triangle and quadrangle conveniently; conveniently bisects angle and line segment, measures angle, draws parallel line, lace line and coordinate line; and also can be used for measuring object. The utility model can fundamentally satisfy the demands of drawing.

Description

Square gauge

The utility model relates to a kind of stationery, specifically belongs to a kind of drawing instrument.

In the existing drawing instrument, compasses can be drawn circle and arc, trisquare can be drawn straight line and right angle, and set square, ruler also can be drawn a lot of geometric figures, but these drawing instruments all can not the unicursal quadrate, perhaps square, or irregular quadrilateral, or triangle or the like at any angle.Many geometric figures need several drawing instruments to cooperate picture just can finish several times, waste time and energy, and this is deficiency and shortcoming that present drawing instrument exists.

This practical purpose is to provide a kind of can draw geometric square gauges such as triangle, quadrangle quickly and easily.

The technical solution of the utility model is: a kind of square gauge, by two angles angle square, change chi, draw the circle chi, lace slide calliper rule and swivel nut are formed, it is characterized in that: two angles angle square one end have one with the fixed amount hornwork of chi one, there is chute at chi body ordinate center, all there is size scale both sides, the other end of chi is equipped with the protractor that an energy slides by chute, change the chi tip by swivel nut and the assembling of fixed amount hornwork, have in size scale faces, it is most advanced and sophisticated by built-in prong swivel nut and bevel protractor and the angle square assembling of two angles to draw the circle chi, lace slide calliper rule two ends by spiral degree of tightness card with draw the circle chi and change the chi assembling, its lace line has in size scale faces outwardly; Changeing chi one end is tack, and the other end is the nib shape, and tip bottom line place has circular hole, and 0 graduation mark is to traverse line, with the longitudinal centre line formation cross hairs to nib; Drawing circle chi one end is tack, and the other end is the nib shape, and place, tip bottom has an oval fine setting hole, and all there is size scale the chi both sides, the equidistant aperture that has of its center line; Lace slide calliper rule one side has size scale, and opposite side is a rickrack, has chute along center line, and at one of chi, chute has a circular hole before; The bevel protractor back side is stained with the positioning strip that matches with two angles angle square one side width; Its fixedly swivel nut form by band cap screw rod and band cap nut; The stretching structure employing activity ball pen type of its built-in needle point swivel nut, have a structure of button, regulating tooth and spring; Its spiral degree of tightness card top is that screw rod and nut are used, and the bottom is and changes chi and draw the clamp that circle chi width equates.

The utility model, various combination by four rulers uses, can draw multiple geometric form figure quickly and easily, especially can draw quickly triangle, quadrangle and angle at any angle, can also divide angle, bisector line segment, measuring angle easily equally, draw parallel lines, lace line, coordinate line, can also card amount object, only this stationery can satisfy the requirements of one's work that chart substantially.

Accompanying drawing 1 is the utility model assembling floor map;

Accompanying drawing 2 is that the utility model is as the triangular compass schematic diagram;

Accompanying drawing 3 is that the utility model is drawn circle chi work schematic diagram;

Accompanying drawing 4 is the utility model bevel protractor structure figure;

Accompanying drawing 5 is the built-in prong swivel nut of the utility model exploded views;

Accompanying drawing 6 is the utility model spiral degree of tightness card schematic diagrames.

Below in conjunction with accompanying drawing this practicality is described further.

1 is two angles protractors among the figure, the 2nd, and chute, the 3rd, pointer, the 4th, bevel protractor, the 5th, built-in prong swivel nut, the 6th, fine setting hole, the 7th, picture circle chi, the 8th, picture circular hole, the 9th, the lace slide calliper rule, the 10th, spiral degree of tightness card, the 11st, change chi, the 12nd, cross hairs, the 13rd, fixing swivel nut, the 14th, pen, the 15th, positioning strip, the 16th, swivel nut, the 17th, button, the 18th, regulating tooth, the 19th, spring, the 20th, prong, the 21st, nut, the 22nd, spiral shell base.According to making two angles angle square described in the above technical scheme respectively, bevel protractor, change chi, draw circle chi and lace slide calliper rule and fixing swivel nut, built-in prong swivel nut and spiral degree of tightness card, the fixed amount hornwork of the most advanced and sophisticated position that will change chi then and two angles angle square assembles by fixing swivel nut and is connected, to draw the most advanced and sophisticated position of circle chi and be connected by built-in prong swivel nut assembling with bevel protractor with two angles angle square, its lace slide calliper rule and spiral degree of tightness card are according to using needs whether to assemble.

Two angle angle squares of the utility model and bevel protractor are used, and can measure the number of degrees at two angles simultaneously, are used by connection with changeing chi, can make 360 degree and rotate, and can measure the number of degrees at angle exactly, and can divide, segment angle equally; Draw circle chi one end because of telescopic prong is housed, draw bowlder and prong is stretched out as the center of circle fix, and nib is inserted aperture in the chi, rotating around prong can picture arc or circle, it can be more accurate by adjusting the position of built-in prong swivel nut in ellipse fine setting hole, make the arc or the circle that draw; With two angles angle square, bevel protractor, changeing chi is in the same place with picture circle chi assembly, can the draw triangle of different shape, this structure figure that straight line links to each other with arc that also especially conveniently draws, the independent use of lace slide calliper rule not only can be drawn lace, and length that can be by two spiral degree of tightness card card amount objects, diameter etc., use with above-mentioned three chi assemblies, the quadrangle of the different shape that can draw comprises parallelogram, rhombus, square, rectangle and trapezoidal or the like.
