Abstract

The utility model provides a multifunctional ruler and belongs to a mathematical tool. The structure of the ruler comprises a positioning ruler and a rotary ruler. The left part of the positioning ruler is provided with a protractor and is fixedly connected with the lower part of the protractor. The left part of the rotary ruler is hinged with the left part of a center line of the positioning ruler, i.e. the position of the center point of the protractor. A guide track is arranged in the middle of the rotary ruler along the center line of the rotary ruler. Rotary scales are formed at the upper end of the rotary ruler along the ruler edge. Positioning scales are formed at the lower end of the positioning ruler along the ruler edge. The positioning scales correspond to the rotary scales. Compared with the prior art, the ruler has the characteristics of reasonable design, simple structure and the like, is convenient to use, is convenient to draw an angle and has multiple functions.

Description

A kind of multi-functional chi of using
Technical field
The utility model relates to a kind of mathematics apparatus, specifically a kind of multi-functional chi of using.
Background technology
On the primary school mathematics class, teacher's teaching need be drawn different angles on blackboard angle is the problem that often runs into; Also be so when carrying out the drafting at angle when the student does one's assignment on paper, common way is to reserve a bit with pen earlier, finishes horizontal line with ruler from this point again, has surveyed angle with protractor then, with pen it is drawn again.These situations allow the academics and students feel loaded down with trivial details, have also reduced learning efficiency simultaneously.
Summary of the invention
Technical assignment of the present utility model is at the deficiencies in the prior art, and a kind of multi-functional chi of using reasonable in design, simple in structure is provided.
The technical scheme that its technical problem that solves the utility model adopts is: comprise positioning rule and rotary ruler, the positioning rule left part is provided with protractor and is connected to a fixed with its underpart, described rotary ruler left part and positioning rule center line left part are that the protractor center position is hinged, the rotary ruler middle part is provided with the guiding road along the rotary ruler center line, rotary ruler upper end edge chi limit is provided with the rotation scale, described positioning rule lower end edge chi limit is provided with the location scale, and the location scale is corresponding with the rotation scale.
Rotary ruler and positioning rule interface point are on the center line of rotary ruler.
Rotary ruler is identical with the positioning rule width.
Guiding road center line and rotary ruler center line overlaid.
During picture, the positioning rule center line is aimed at certain straight line and summit thereof respectively with the protractor central point, delimit the angle of different angles, then nib is stretched in the guiding road line straight line at another side place at angle that can draw by the swing rotary ruler; When placing same horizontal line with rotary ruler and positioning rule doubling or with the scale on rotary ruler and the positioning rule, this multipurpose ruler can be used as ruler and use.
Of the present utility model a kind of multi-functional with chi compared with prior art, the beneficial effect that is produced is:
1, time saving and energy saving, can make things convenient for teacher or student to carry out the drafting at different angles, and can make the angle of drafting comparatively accurate.
2, both can draw special angle, and also can be used as ruler and use, accomplish the purpose that a chi is used more.
3, have characteristics such as reasonable in design, simple in structure, easy to use, function admirable, practicality, thereby have excellent popularization and use prospect.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Among the figure, 1, rotary ruler, 2, rotate scale, 3, the guiding road, 4, protractor, 5, center line, 6, positioning rule, 7, the location scale.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done following detailed description the in detail.
As shown in drawings, a kind of multi-functional chi of using of the present utility model, its structure comprises positioning rule 6 and rotary ruler 1, positioning rule 6 left parts are provided with protractor 4 and are connected to a fixed with its underpart, described rotary ruler 1 left part and positioning rule 6 center lines 5 left parts are that protractor 4 center position are hinged, rotary ruler 1 middle part is provided with guiding road 3 along rotary ruler 1 center line 5, rotary ruler 1 upper end edge chi limit is provided with rotates scale 2, described positioning rule 6 lower end edge chi limits are provided with location scale 7, and location scale 7 is corresponding with rotation scale 2.
Rotary ruler 1 and positioning rule 6 interface points are on the center line 5 of rotary ruler 1.
Rotary ruler 1 is identical with positioning rule 6 width.
Guiding road 3 center lines and rotary ruler 1 center line 5 overlaids.
Of the present utility model a kind of multi-functional simple and convenient with its processing and fabricating of chi, processing and fabricating gets final product shown in the by specification accompanying drawing.
Except that the described technical characterictic of specification, be those skilled in the art's known technology.
