Description

Lattice rule

Technical field

The invention belongs to Multkfunctional stationery field, be specifically related to a kind of lattice rule.

Background technology

Along with the raising of educational level, student's lessons scope is increasingly wider, improves the tool kind of Students ' Learning efficiency also More and more.The stationery that student commonly uses includes ruler, set square, protractor and compasses etc..But these stationery are of a great variety, Need switching accordingly frequently during picture, use and carry the most very inconvenient.If one of which or several is omitted in carelessness, can lead Cause student cannot normally learn and take an examination.

In existing multi-functional roller, the function for measurement and 15 ° of angles of making does not realizes substantially, draws in application During function, during picture circle when 270 °, two, left and right hands is twisted together, inconvenient

Summary of the invention

In order to solve problems of the prior art, the invention provides a kind of lattice rule, this lattice chi solves existing Having stationery function singleness in technology, sample number is various, the problem easily omitted.

It is as follows that the present invention solves the technical scheme that technical problem used:

Lattice rule, this lattice chi includes that lattice chi body, lattice chi body are made up of isosceles right angle triangle and right angle triangle； Described right angle triangle be acute angle be 30 ° and the right angle triangle of 60 °；Described isosceles right angle triangle and right angle triangle straight Angle overlaps；One right-angle side of isosceles right angle triangle falls on the right-angle side of right angle triangle, and another right-angle side falls directly On the extended line of another right-angle side of angle set square；Arranging scale 0 on right-angled apices, two right-angle sides set gradually quarter Degree, each scale is correspondingly arranged an aperture accommodating nib；One protractor, the water of described protractor are set on lattice chi body Horizontal line limit long with right angle is parallel；The upper surface of described lattice chi body is in same level.

The invention has the beneficial effects as follows: lattice rule of the present invention is provided with isosceles right angle triangle, right angle triangle, angulation The function of device, ruler and compasses, can draw arbitrarily angled with the hollow out of throughput hornwork horizontal line and EXT scale line, and pass through lattice Characteristic angle on chi body quickly draws 15 °, 30 °, 45 °, 60 °, 90 ° and 135 ° of angles, can be surveyed by the scale on right-angle side Measure and draw the straight line of certain length, and drawn the circle of certain radius scope by the aperture on right-angle side.In the process drawing circle In, it is not necessary to two handss are twisted together, it is only necessary to by the line that aperture is corresponding, find on another right-angle side equidistant little Hole, opposite direction coordinates, draws a complete circle.Owing to being provided with line between the aperture of two identical scales, changing aperture During, it is not easy to obscure, the mistake that radius length changes will not occur.Present configuration is simple, it is simple to carry, and function is rich Richness, with low cost, it is adaptable to students in middle and primary schools learn to use and the popularization of people in educational circles.

Accompanying drawing explanation

Fig. 1 lattice rule of the present invention structural representation.

In figure: 1,30 ° of angles, 2,45° angle, 3,15 ° of angles, 4,60 ° of angles, the 5, first aperture, 6, scale 0,7, second orifice, 8, Protractor and 9, hollow out.

Detailed description of the invention

With embodiment, the present invention is described in further details below in conjunction with the accompanying drawings.

As it is shown in figure 1, lattice rule, this lattice chi includes lattice chi body, and lattice chi body is by isosceles right angle triangle and right angle Set square unites two into one composition；Right angle triangle be acute angle be 30 ° and the right angle triangle of 60 °；Isosceles right angle triangle is with straight The right angle of angle set square overlaps；One right-angle side of isosceles right angle triangle falls on the long limit of the right-angle side of right angle triangle, Corresponding angle is 30 ° of angles 1, and another right-angle side of isosceles right angle triangle falls at another right-angle side of right angle triangle On minor face extended line, corresponding angle is 45° angle 2.The right angle minor face of lattice chi body arranges 60 ° of angles 4 by opening, The position at 60 ° of angles is outside scale range.Opening angle is 15 ° of angles 3.Lattice chi body be shaped like kite.

Arranging scale 06 on right-angled apices, two right-angle sides set gradually scale, and unit is 1mm, can measure and draw The length of required straight line in going out range.Every 0.5mm is correspondingly arranged an aperture accommodating nib；Two equivalently-sized apertures, By solid line, dotted line or the concave connection being arranged on lattice chi body.Realize the function of compasses.When wanting picture circle when, one In penholder enters the aperture of scale 0 correspondence and fix, another penholder enters the first aperture 5 of respective radius scale on right-angle side In, with fixing point as axle, rotary picture circle；When signing in 270 ° when, two arms are twisted together, it is impossible to carry out；At this moment, pass through With the line of on scale two apertures, find the second orifice 7 with scale on another right-angle side the most accurately, smoothly complete Draw circle.The upper surface of described lattice chi body is in same level.

On lattice chi body, being parallel at right-angle side arrange a protractor 8, the horizontal line of protractor 8 is put down with right-angle side OK, the horizontal line of protractor and EXT scale line are hollow out 9, can measure and draw required angle.

The material of lattice chi body is silica gel, plank or duroplasts.Can be placed in books and use as bookmark.
