Description

multifunctional ruler

technical field

The utility model relates to a multifunctional ruler, which belongs to the technical field of geometric drawing instruments.

Background technique

Current geometric drawing rulers include set rulers and combination rulers. The traditional set of rulers is a set of drawing instruments composed of independent drawing tools such as a ruler, a set square, a compass, and a protractor. In use, a straight edge is often used to draw a straight line, a number axis and a plane Cartesian coordinate system, and various triangles are drawn with a set square. Compasses draw various arcs, draw or measure angles with a protractor, sometimes put down the ruler and then take the compass, put down the compass and then take the protractor, which is very inconvenient to use and carry. The current various combined rulers have some intelligent designs, and various drawing tools have been combined to varying degrees. However, these combined rulers have problems such as large space occupation by their shapes, overly complicated structures, inflexible activities, and inconformity with usage habits. achieve good results. The utility model patent with the application number 201220507914.3 discloses a multifunctional ruler, which has the functions of surveying and mapping straight lines, angles and arcs, and has a compact structure, small shape, light weight, and is easier to carry. When the ruler draws an arc, the tip of the pen can only be placed in a few specific holes, and the radius of the drawn arc is limited to the position of the hole on the ruler, so the scope of use is limited.

There is a dial on the surface, and the dial is provided with an angle scale line from 0° to 360°. There is an angle pointer on the end of the auxiliary ruler arm near the rotating shaft. The angle pointer is located on the center line of the auxiliary ruler arm in the width direction and points to the axis of the rotating shaft. The sliding block includes an upper panel and a lower panel. The upper panel and the lower panel can be opened or snapped together and slide back and forth along the slideway. There is a pen hole in the center of the upper panel and the lower panel, and there are pen holes on both sides of the pen hole. The scale pointer points to the scale lines on both sides of the auxiliary scale arm.

Preferably, the scale values on one side of the main scale arm and the auxiliary scale arm are positive, and the scale values on the other side are reverse.

Preferably, the division value of the angle scale line on the dial is 1° to 15°.

The beneficial effects produced by adopting the above-mentioned technical scheme are: the multifunctional ruler provided by the utility model can use the main ruler arm to draw straight lines, angle lines, and measure dimensions, and the main ruler arm and the auxiliary ruler arm can be used together to measure angles and draw arbitrary radii It combines the functions of traditional drawing tools such as rulers, set squares, protractors, and compasses. It can draw various conventional graphics. It has simple structure, flexible activities, and easy use. , complete functions, small shape and easy to carry.
