Abstract

The utility model relates to a multifunctional ruler which comprises a rotary ruler (1), a fixed ruler (2), a screw (5) and a nut cover (6), wherein the rotary ruler (1) and the fixed ruler (2) are connected as a whole by the screw (5) and the nut cover (6); the front end of the rotary ruler (1) is provided with a screw hole (9) and an indicator line (8) and is in a semicircular shape, the rear end thereof is provided with a semicircular notch (10), and the upper surface and the lower surface of the edge of one side part are respectively provided with scale yards (7) and edge strips (11); the front end of the fixed ruler (2) is provided with a screw hole (13) and scale yards (12) and is in the semicircular shape, the rear end thereof is provided with a round hole (14) in which a ring thimble (3) is arranged; and the ring thimble (3) is provided with a compass (4) with a scale dial (15). The multifunctional ruler can be folded, and realize the functions of drawing long and short straight lines, parallel lines, horizontal lines, vertical lines and angles, measuring length and angles, and pointing southward.

Description

A kind of multi-functional ruler

Technical field

The utility model relates to a kind of surveying and mapping tool, especially can make things convenient for the multi-functional ruler of the long straight line of picture, parallel lines, angle.

Background technology

Usually draw geometric figures such as straight line, parallel lines, angle and need use instruments such as ruler, set square, protractor, compasses, these instrumental functions are single, classification differs, and uses very inconveniently, and the ruler that has can not be drawn long straight line, parallel lines at all; It is very difficult to draw parallel lines with ruler, and the drawn parallel lines depth of parallelism is not high, does not reach requirement; Draw angle or when taking measurement of an angle, then need operate in addition a plurality of instruments with ruler, the much extra auxiliary views of picture are so just lost time, and operating efficiency can not improve.

The utility model is at the deficiency of above-mentioned series technique, a kind of multi-functional ruler is provided, it can make things convenient for the long straight line of picture, parallel lines, horizontal line, vertical line, angle, it can also measure length, measuring angle, guide, it gathers multi-function in integral whole, rotatable folding is convenient for carrying, and can increase work efficiency greatly.

The utility model content

The utility model provides a kind of multi-functional ruler, this ruler changes chi by one and a scale connects and composes through screw, nut cap, can fold, can realize picture length straight line, draw parallel lines, draw horizontal line, draw vertical line, draw angle, measure length, measuring angle, guide function.

Realize that the technical scheme that the utility model purpose is adopted is: a kind of multi-functional ruler, it comprises changes chi (1), scale (2), screw (5), nut cap (6), changeing chi (1) and scale (2) is connected in one by screw (5), nut cap (6), it is characterized in that: described commentaries on classics chi (1) front end is provided with screw hole (9) and cursor line (8), front end semicircular in shape shape, the rear end is provided with half circumferential notch (10), and a side margins upper and lower surface is respectively arranged with scale sign indicating number (7), edge strip (11); Described scale (2) front end is provided with screw hole (13) and scale sign indicating number (12), front end is the semicircular in shape shape also, the rear end is provided with a circular port (14), and annulus lasso (3) is set in the circular port (14), and the compass (4) of a band dial (15) is installed on the annulus lasso (3).

The utlity model has following beneficial effect:

(1) multi-functional, the length straight line be can draw, draw parallel lines, draw horizontal line, draw vertical line, draw angle, length, measuring angle, guide measured.

(2) the blade design is small and exquisite, can fold, and is easy to carry.

(3) structure is ingenious, and cost is low, and is very practical, can improve work efficiency.
