Abstract
The utility model relates to a multifunctional angle rule. A main body is a ruler which is provided with a level instrument which is a disc shape, the circumference of which is marked with angle scales. The volume of liquid filled inside is half of the volume of a whole circular inner cavity. The level instrument is fixed on the surface of the ruler in a gluing or an inlaid form. The utility model has the advantages of simple structure and easy fabrication. The circumference of the disc-shaped level instrument is marked with the angle scales which are directly fixed on the surface of the ruler. When a lines is drawn, the angle of the line which is drawn and a level line can be visually seen. The utility model can be used as a drawing tool on a blackboard when a teacher teaches, and has more convenient use than a protractor and a triangle adopted at present. Meanwhile, the multifunctional angle rule can also be applied to the field of building and decoration.
Description
Technical field
The utility model belongs to the drawing appliance field, specifically a kind of multifunctional angular chi.
Background technology
The existing teachers ' teaching ruler amount of having only length and the function of drawing straight line, when drawing the straight line of certain angle on the need blackboard, then need to adopt protractor, set square or compasses are used in combination just and can finish, operation is trouble very, at the problems referred to above, current some solutions that also occurred, as the disclosed bevel protractor of Chinese ZL02261620.9 patent " multifunction level meter ", comprise a horizontal ruler, horizontal ruler is provided with a level meter, level meter is provided with readable dish and inside is equipped with the weight pointer, this utility model utilizes weight pointer and vertical direction angle to determine ruler institute drawing beeline angle, because the weight pointer is fixed in the level meter by an end points, there is certain friction, the precision of pointer indication is affected.
Summary of the invention
The utility model is to improve on the basis of existing ruler, and its objective is provides a kind of multifunctional angular chi that can draw various angles flexibly.
According to the above-mentioned purpose requirement, the utility model is realized by the following technical solutions:
A kind of multifunctional angular chi, its main body are a ruler, and ruler is provided with a level meter.Described level meter is discoid, is marked with angle index on its periphery, and the volume of interior dress liquid is half of whole round cavity volume, and level meter is fixed on the ruler surface with the form of pasting or inlay.
The utility model is simple in structure, and is easy to manufacture, with plate-like level meter periphery mark angle index, and directly is fixed on the ruler surface, can find out the angle of institute's line drawing bar and horizontal line when drawing lines very intuitively.Drawing instrument when the utility model can be used as teachers ' teaching on blackboard, more convenient than protractor, the set square use of present employing, also can be applicable to building and finishing field simultaneously.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
The specific embodiment
For the ease of understanding, the utility model is further described in detail below in conjunction with accompanying drawing:
Main body of the present utility model is a ruler 1, is inlaid with a discoid level meter 2 on ruler 1 surface.Be marked with angle index on the periphery of level meter 2, the angle index deflection scale parallel with ruler 1 long limit is designated as 180 ° (perhaps 0 °), level meter 2 shells adopt transparent material to make, liquid 3 is housed in its inside, the volume of liquid 3 is half of whole round cavity volume, guarantees that when horizontal positioned liquid 3 surface line overlap with 180 ° of graduation marks.
But level meter 2 forms with interior dress liquid 3 integral productions, also can stay a hand-hole earlier on the level meter shell, treats the hole to be sealed after liquid injects again.
The utility model is simple in structure, and is easy to manufacture, with plate-like level meter periphery mark angle index, and directly is fixed on the ruler surface, can find out the angle of institute's line drawing bar and horizontal line when drawing lines very intuitively.Drawing instrument when the utility model can be used as teachers ' teaching on blackboard, more convenient than protractor, the set square use of present employing, also can be applicable to building and finishing field simultaneously.
