Abstract
The invention provides a multipurpose ruler which can achieve operation such as measurement, outdoor single drawing and marking. According to the multipurpose ruler, a ring is arranged inside a triangular plate, a circumference gauge is embedded in the ring, a rotary shaft is arranged at the center of the circumference gauge, and a level gauge is arranged on the rotary shaft. The multipurpose ruler is simple in structure, convenient to operate, and capable of being used for achieving surveying and mapping operation in the fields such as teaching and outdoor construction.
Description
Technical field
The present invention relates to tolerance and drawing field, specifically a kind of drawing that can be used in multiple fields particularly facilitates outdoor drawing, construction multipurpose ruler.
Background technology
At present, in the processes such as teaching, field construction, often use the instrument of sizing, angle, the most function singleness of instrument of using, is used in combination time error larger, sometimes needs many people to be used in conjunction with, and teacher or master worker operate and waste time and energy.
Summary of the invention
For addressing the above problem, the invention provides a kind of multipurpose ruler, can realize tolerance, the multiple operations such as outdoor single drawing, graticule.
The present invention is achieved in that set square inside arranges lasso, and lasso has been nested with circumference gauge, and there is rotating shaft at circumference gauge center, and level meter is set in rotating shaft.
The outer setting respectively of the lasso lasso parallel lines parallel with each limit of set square.
Described level meter can be take rotating shaft and as the center of circle, done 360 ° of rotations.
Described rotating shaft can be done at circumference gauge center 360 ° of rotations.
Described circumference gauge can freely rotate in nested lasso.
Set square can be made into applicable shape such as square grade.
The invention has the beneficial effects as follows: simple in structure, easy to operate, can realize fast the mapping operation in the fields such as teaching, outdoor construction.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, be described further.
Fig. 1 is structural representation of the present invention.
In figure 1, level meter, 2, rotating shaft, 3, circumference gauge, 4, lasso, 5, set square, 6, lasso parallel lines.
The specific embodiment
As shown in the figure, set square 5 inside arrange lasso 4, and lasso 4 has been nested with circumference gauge 3, and there is rotating shaft 2 at circumference gauge 3 centers, and level meter 1 is set in rotating shaft 2.
During tolerance, can measure with the scale on set square 5.
When carrying out angle mapping and drawing the figure of certain angle, first with level meter 1, determine datum line, adjusting the required angle of circumference gauge 3, now, circumference gauge 3 keeps motionless, adjusts lasso 4 outer collar parallel lines 6 to required angle value, can draw out the sideline of required angle.
Claims (5)
