Abstract
The utility model discloses an instrument capable of drawing scalene triangles, which includes three station meters; the three station meters are hinged and connected end to end; each station meter is formed by the sleeve joint of at least two sections of bushings, and can extend and retract randomly; and scales are formed on the three station meters. When drawing a triangle, people can adjust the instrument to the required length through the retractable station meters, use a pen to draw along the inner side or the outer side, and obtain the drawn triangle; the use is convenient and flexible; and the station meters have strong retractility, so that triangles with arbitrary sides can be drawn. The instrument has the advantages of convenient and flexible use, simple structure, good effect, etc.
Description
Technical field
The utility model relates to a kind of a kind of instrument of drawing arbitrary triangle of drawing arbitrary triangle.
Background technology
When several people are in study, need to draw various figures, and wherein triangle is one of figure of the most normal drafting.Not only will calculate the length of side during general free-hand drafting triangle, also will calculate angle, trouble comparatively though many drafting instruments are arranged in the prior art, exists to be not suitable for drawing triangle, to use inconvenience or complex structure and other problems mostly.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of instrument of the arbitrary triangle drawn easy to use.
The purpose of this utility model is achieved through the following technical solutions:
A kind of instrument of drawing arbitrary triangle comprises three basic chis, and twisting connects between three basic chi head and the tail, and basic chi is socketed to form by at least two joint sleeve pipes, can carry out flexible arbitrarily.
Described basic chi is socketed to form by three joint sleeve pipes.
Described basic chi is provided with scale.
When needing to draw triangle, as long as know the leg-of-mutton length of side of required drafting, just can draw: be adjusted to Len req by telescopic basic chi earlier by a kind of instrument of drawing arbitrary triangle of the present utility model, then with the pen along the inboard or the outside draw, promptly obtain the triangle of required drafting, easy to use, flexible, because basic chi scalability is strong, so can draw the triangle of any length of side.The utlity model has advantage such as flexible, simple in structure, effective easy to use.
Description of drawings
Accompanying drawing is a kind of structural representation of drawing the instrument of arbitrary triangle of the present utility model.
Wherein, 1, sleeve pipe; 2, basic chi; 3, scale.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described;
Embodiment: a kind of instrument of drawing arbitrary triangle, comprise that 2, three basic chi 2 head and the tail twistings of three basic chis connect, basic chi 2 is socketed to form by three joint sleeve pipes 1, can carry out stretching arbitrarily, and basic chi 2 is provided with scale 3, as shown in drawings.
During use, earlier by scale 3, the length of regulating three basic chis 2 is to the required length of side, draw along basic chi 2 inboards with pen then, promptly obtain the triangle of required drafting, easy to use, flexible, the utlity model has advantage such as flexible, simple in structure, effective easy to use.
Claims (2)
1. the instrument that can draw arbitrary triangle comprises three basic chis (2), it is characterized in that: twisting connects between three basic chis (2) head and the tail, and basic chi (2) is socketed to form by at least two joint sleeve pipes (1).
2. a kind of instrument of drawing arbitrary triangle according to claim 1 is characterized in that: described basic chi (2) is provided with scale (3).
