Abstract
The utility model discloses a multifunctional ruler comprising a plurality of indented notches with unequal angles and semi-circular notches with unequal radii and a straight edge with scales. The utility model can solve the problem that the ruler is incapable of drawing angles for common use without a protractor, so that, people who buys a ruler is capable of not only using the ruler for general purposes, but also drawing specific angles and circular arcs. The utility model has the characteristics of simple structure, convenient use and high precision, and facilitates mass production, popularization and application of the ruler.
Description
Technical field
The utility model belongs to a kind of multi-functional ruler.
Background technology
The ShenYang, Liaoning Province city multi-functional ruler of utility model prospectus CN2576496-also can be used for picture angle commonly used (30 degree, 45 degree, 60 degree, 90 degree), and this ruler mainly is made of ruler I, ruler II, rivet.It is characterized in that: the chi face position of ruler I is connected the chi face position of ruler II with rivet, and the medium position of rivet inserts the chi face aperture position that is connected ruler I, ruler II.Though this ruler also can be drawn angle commonly used, structure is a bit complicated.The utility model not only can be drawn angle commonly used can also draw the circular arc and the circle of certain radius, and structure very simple, easy to use, be convenient to produce in a large number and apply, the degree of accuracy is higher, the scope of application is wider.
Summary of the invention
Task to be solved in the utility model is draw accurately under the condition that does not have protractor and the compasses several angles commonly used and the semi arch or the circle of certain radius.
Be to realize the purpose of this utility model, add at the offside of the graduated side of common ruler and have the zigzag recess of accurate angle value and the semi arch recess of certain radius value.The summit at angle is at 1/3rd wide places of chi, and arc radius can mark angle value and radius value at the place, summit at angle and the summit of semi arch according to the wide change of chi.
The utility model has not only kept the function of traditional ruler, and newly-increased design can draw under the situation that does not have protractor and the compasses angle of accurate angle and the circular arc or the circle of certain radius.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Accompanying drawing is the plane of the specific embodiment of the present utility model.
The specific embodiment
The semi arch that the zigzag recess that multi-functional ruler shown in the Figure of description is not waited by angle, radius do not wait and be used for the straight flange that has scale that the picture straight line uses and form.The summit at zigzag angle is positioned on the straight line at wide 1/3rd places of chi, and the radius of circular arc can be according to the wide setting of chi, as can be made as chi wide 1/2nd, 1/4th, eight/first-class.The number of circular arc can change according to chi is long.Summit and circular arc summit place's angular dimension value and radius value at the angle.
Claims (2)
1. a multi-functional ruler is characterized in that adding zigzag recess that has special angle and size and the semi arch that radius does not wait at the offside of the graduated side of the common ruler of tradition according to design.
2. multi-functional ruler according to claim 1 is characterized in that: the angle of zigzag recess has 30 degree, 37 degree, 45 degree, 53 degree, 60 degree, 90 degree.
