Description

Multifunctional ruler

Technical Field

The utility model relates to a multifunctional ruler, it belongs to articles for daily use technical field.

Background

The common ruler can only be used for measuring and drawing the length, but cannot be used for measuring, drawing and other functions of the angle, other tools are often needed for assistance at this time, inconvenience is caused in the using process, and the more tools are, the more the tools are troublesome to store, and the tools are easy to lose. In the prior art, the protractor is directly combined with the straight ruler, and the protractor is additionally arranged on the straight ruler, so that two tools are simply overlapped, the cost is increased, more materials are needed, the original simple shape of the straight ruler is changed, and the ruler is not easy to carry due to the irregular shape; the length scale of the ruler is sacrificed, and the function of the ruler when the ruler is independently used for drawing the length is influenced. And the ruler capable of measuring the angle is only provided with one function, people also need other auxiliary tools when drawing circles and curves, and the ruler is inconvenient to carry and does not have the functions of measuring levelness, temperature and scratching itch.

SUMMERY OF THE UTILITY MODEL

The utility model provides a multi-functional ruler to the not enough of existence among the above-mentioned prior art.

The utility model provides an above-mentioned technical problem's technical scheme as follows:

the utility model provides a multifunctional ruler, includes the ruler body, the upper left corner of ruler body is equipped with the circle device of drawing, the upside edge of ruler body is equipped with the length scale, the downside edge of ruler body is equipped with the angle scale, and the centre top-down of ruler body is equipped with thermometer and curve frame, and the centre of angle scale upside is equipped with the spirit level.

Preferably, the circle drawing device comprises a fixed shaft, the bottom end of the fixed shaft is fixed inside the ruler body, and a cap is fixed at the top end of the fixed shaft.

Preferably, the centre of the dead axle coincides with a zero point of the length scale.

Preferably, the fixed shaft is sleeved with a thin rope, and the other end of the thin rope is connected with an elastic ring.

Preferably, the right side edge of the ruler body is provided with a wave-shaped bulge.

Preferably, the zero points of the length scale and the angle scale are arranged at the left end of the ruler body.

Compared with the prior art, the beneficial effects of the utility model are that: the multifunctional ruler can realize multiple functions including drawing straight lines, curves, circles, parallelism, temperature and scratching, can directly draw circles with different diameters, is accurate in measurement, does not need to draw circles after being measured by compasses, is simple to operate, is convenient to carry, and occupies a small space.

Detailed Description

The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.

The utility model provides a multifunctional ruler, includes ruler body 1, the upper left corner of ruler body 1 is equipped with draws circle device 2, the upside edge of ruler body 1 is equipped with length scale 3, the downside edge of ruler body 1 is equipped with angle scale 4, and the centre top-down of ruler body 1 is equipped with thermometer 5 and curve frame 6, and the centre of the 4 upsides of angle scale is equipped with spirit level 7.

Circle drawing device 2 includes dead axle 8, the bottom mounting of dead axle 8 is in the inside of ruler body 1, the top of dead axle 8 is fixed with cap 9.

The centre of the dead axle 8 coincides with the zero point of the length scale 3.

The fixed shaft 8 is sleeved with a thin rope 10, and the other end of the thin rope 10 is connected with an elastic ring 11.

The right side edge of the ruler body 1 is provided with a wave-shaped bulge 12.

The zero points of the length scale 3 and the angle scale 4 are arranged at the left end of the ruler body 1.

Example 1

When the ruler is used, the ruler body 1 is placed on a plane, a straight line can be drawn by drawing a line along the upper side edge of the ruler body 1 with a pen, and the value of the length scale 3 corresponding to the end part where the straight line is finished is the length of the straight line; the curve can be obtained by drawing a line in the curve frame 6 by using a pen. And (3) observing whether the hollow position on the level gauge 7 at the lower part of the ruler body 1 is in the middle position of the level gauge 7, if so, proving that the measured surface is horizontal, otherwise, the measured surface is an inclined surface. When drawing a circle, the elastic ring 11 is sleeved at the end of a pen, then the radius of the circle to be drawn is selected to be long, the excessive length of the string 10 is wound on the pen, the straight ruler body 1 is fixed, the zero point of the straight ruler body 1 is coincided with the circle center, and the pen is held by a hand to pull the string 10 and rotate for a circle around the zero point, so that the circle can be drawn. The ambient real-time temperature is known by reading the reading on the thermometer 5. The side with the bulge 12 is close to the skin, so that the itch scratching can be assisted.

Example 2

Take an example of drawing an angle of 70 °:

determining one side of the angle, determining a vertex O of the angle to be drawn on the side, generally one end point of the side, coinciding a zero scale mark of the short side of the ruler body 1 with the determined side, and the upper end point of the zero scale mark with the vertex O of the angle, as shown in fig. 4, finding the angle to be drawn at 70 degrees on the lower side of the ruler body 1, determining the point, and connecting the point with the vertex O of the angle in a straight line, thereby completing the angle drawing.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
