Abstract
The invention relates to a folding plotting and angle gauging tool. The angle gauging tool consists of two isometrical angle gauges; the two angle gauges are aligned by bottom edges and are movably connected to form a whole; opposite surfaces of the top separated ends are connected in a clamped way; the centers of the bottom sides of the angle gauges are in shaft connection with a range pole; a cambered sliding chute is formed along the cambered sections of the angle gauges; and the top end of the range pole is a right angle rod and is inserted into the sliding chute. Length scale lines are marked on the surface of the range pole by taking the rotating end of the range pole as an original point. The folding plotting and angle gauging tool has the advantages of reasonable structure, high convenience and practicality, wide application range and the like.
Description
Technical field
The present invention relates to a kind of study article, especially a kind of drawing, survey tool.
Background technology
[0002] well-known, people often need to use various drawing and survey tool in study and work, and wherein the frequency of utilization with protractor and ruler is the highest especially.But present protractor all adopts the semicircular ring project organization, can only take measurement of an angle or the draw circles arc; For drawing requirements such as angle or drafting circular pattern; Present protractor then can't be finished the work, and people can only draw and measure by compasses and ruler, because instrument is more; Therefore inconvenience is deposited and is carried, and makes troubles to people.
Summary of the invention
The purpose of this invention is to provide a kind of folding drawing angulation instrument rational in infrastructure, convenient and practical, widely used.
Angulation instrument of the present invention is made up of two big protractors such as grade, and two protractor base alignment also flexibly connect formation integral body, and the top cassette of two protractors links together; Axle connects mark post at protractor center place, offers cambered way along this protractor segmental arc, and the mark post top is the right angle bar and inserts in the slideway.Rotating end with mark post is initial point, at mark post surface marking length graduation mark.
When taking measurement of an angle, the user folds two protractors and places, and relies on the cassette connection to be fixed together both, avoids movable, and normally the use amount hornwork is measured at this moment.When drawing the angle, the user rotates mark post to one side as the angle, protractor base then in slideway, make the another side of mark post as the angle, and guarantees that the angle between mark post and the base is the angle of waiting to paint the angle, just can along mark post and drafting angle, base at last.Draw when circular, the user is open and flat to open two protractors and forms cirque structures, the line drawing circular pattern that just can directly draw along the annular edge.
Compared with present technology; Beneficial effect of the present invention is: rational in infrastructure, convenient and practical, be widely used, function is peculiar, technology is exquisite; Circular pattern can be drawn and angle can be accurately drawn again; And can carry out length and angular surveying, and and be convenient for carrying and deposit, be people's service condition efficiently that facilitates.
Description of drawingsFig. 1 is a stereochemical structure sketch of the present invention.
The specific embodimentIn stereochemical structure sketch of the present invention shown in Figure 1, described angulation instrument is made up of two big protractors 1 such as grade, and two protractor base alignment also flexibly connect formation integral body, and the top cassette of two protractors links together; Axle connects mark post 2 at protractor center place, offers cambered way 3 along this protractor segmental arc, and the mark post top is the right angle bar and inserts in the slideway.Rotating end with mark post is initial point, at mark post surface marking length graduation mark 4.
Claims (2)
1. folding drawing angulation instrument, it is characterized in that: said angulation instrument is made up of two big protractors such as grade (1), and the alignment of two protractors (1) base also flexibly connects and forms wholely, and the top cassette of two protractors links together; Axle connects mark post (2) at protractor (1) center place, offers cambered way (3) along this protractor (1) segmental arc, and mark post (2) top is the right angle bar and inserts in the slideway (3).
