Abstract
The invention discloses an angle measuring compass ruler. The angle measuring compass ruler comprises a supporting leg, an another supporting leg and a rotating shaft; the two supporting legs are connected through the rotating shaft; one supporting leg is provided with a fixing cap, a fixing rod, scale lines and a pen head, and the other supporting leg is provided with a fan-shaped strip box, a shaft handle, a gear shaft and a sucking disc; the fixing cap is connected with the gear shaft through a gear chain; the fixing rod is connected with the fan-shaped strip box through a fan-shaped strip; the gear chain is controlled through the shaft handle; the scale lines are millimeter scale lines; angle lines are formed on the fan-shaped strip. According to the angle measuring compass ruler disclosed by the invention, a protractor is capable of fixing the size of a drawn circle by adopting the gear chain, so the drawn circle is higher in accuracy; by integrating the protractor, a ruler and compasses, the angle measuring compass ruler is capable of realizing multiple functions and is economical, practical, simple to operate, high in practicability and easy to popularize and use.
Description
Technical field
The present invention relates to educational aid applied technical field, especially a kind of angle compasses chi.
Background technology
Compasses are in mathematics and drawing, are used to draw the instrument of circle or string, are usually used in construction with ruler and compasses.The making of compasses
Typically metal, connects by a hinge including two parts, wherein can adjust.
No matter how existing compasses structure changes, and its drawing principle is all basically identical；But existing compasses are deposited
In following deficiency, existing calipers function is more single, and simply simple picture is justified.
Content of the invention
Prior art is difficult to the needs of people, and in order to solve above-mentioned problem, the present invention proposes a kind of angulation circle
Scale, it reaches the effect of one-object-many-purposes using by protractor, ruler together with compasses triplicity.
For realizing this technical purpose, the technical solution used in the present invention is：A kind of angle compasses chi, including leg, leg
And rotating shaft；Described leg and leg are attached by rotating shaft；Described leg is provided with locking cap, fix bar, graduation mark and pen
Head；Described leg is provided with fan-shaped tape drum, axle handle, tooth axle and sucker；Described locking cap is connected by toothed chain bar with tooth axle；Institute
State fix bar to be connected by sector belt with fan-shaped tape drum.
Further, toothed chain bar is controlled by axle handle.
Further, described graduation mark is millimeter graduation mark.
Further, described sector belt is carved with angle line.
Compared with prior art, the invention has the advantages that：This kind of angle compasses chi adopts using by protractor
Wheel chain is fixed the size of drawn circle, makes drawn circle precision higher；This kind of angle compasses chi using by protractor, ruler and
Compasses triplicity together, reaches the function of one-object-many-purposes, economical and practical, simple to operate, practical it is easy to promote the use of.
Brief description
Fig. 1 is the overall structure diagram of the present invention；
In reference：A- leg, B- leg, 1- rotating shaft, 4- toothed chain bar, A1- locking cap, A2- fix bar, A3- scale
Line, A4- nib, B1- sector tape drum, B2- axle handle, B3- tooth axle, B4- sucker, sector belt B11.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is all other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Refer to 1 figure, in embodiments of the present invention, a kind of angle compasses chi, including leg A, leg B and rotating shaft 1；Described
Leg A and leg B is attached by rotating shaft 1；Described leg A is provided with locking cap A1, fix bar A2, graduation mark A3 and nib
A4；Described leg B is provided with fan-shaped tape drum B1, axle handle B2, tooth axle B3 and sucker B4；Described locking cap A1 is passed through with tooth axle B3
Toothed chain bar 4 connects；Described fix bar A2 is connected by sector belt B11 with fan-shaped tape drum B1；Toothed chain bar 4 is carried out by axle handle B2
Control；Described graduation mark A3 is millimeter graduation mark；Described sector belt B11 is carved with angle line.
The present invention reaches one-object-many-purposes function using by protractor, ruler together with compasses triplicity；Wait drawing bowlder
Chain 4 is arranged many long length by axle handle B2 by us；Only need to be by sector when needing the angle drawn by measurement
Read on band B11；Need to measure straight line how long when, only this leg A and leg B need to be closed up, using on leg A
Graduation mark A3 measuring, very convenient, simple to operate.
The above, only presently preferred embodiments of the present invention, not in order to limit the present invention, every skill according to the present invention
Any trickle amendment, equivalent and improvement that art is substantially made to above example, should be included in technical solution of the present invention
Protection domain within.
