Description
Technical field
Compasses are convenient for measuring the present invention relates to articles for use field of charting, more particularly to one kind.
Background technology
Compasses are to draw circular conventional drawing instrument, and there is also various compasses in the prior art.
Chinese invention patent (CN102328533A) discloses a kind of compasses, including center of circle angle and
Circular foot is drawn, center of circle angle is engaged by tooth with the upper end for drawing circular foot and is flexibly connected, also including surveying chi, survey
The midpoint of center of circle angle is fixed at the scale zero of chi by rivet, is carved in the midpoint for drawing circular foot
There is mark.The radius of drawn circle can be determined by side chi.
But, the middle part that chi is arranged at compasses angle is provided in the above-mentioned compasses for providing in the prior art, this
Sample as survey the numerical value that chi is measured be not measured by circle real radius.
The content of the invention
In view of the foregoing defects the prior art has, the present invention is intended to provide a kind of compasses being convenient for measuring,
The circle of certain radius conveniently can be accurately drawn, while also can conveniently measure round radius.
Concrete technical scheme is as follows：
A kind of compasses being convenient for measuring include：Mounting bracket, fix bar, drafting bar and measuring scale；Its
In, fix bar is hinged with the one end for drawing bar with mounting bracket；Fix bar is another relative to mounting bracket
End is provided with fixed pin, draws bar and is provided with drawing pen relative to the other end of mounting bracket；One end hinge of measuring scale
The bottom edge being connected to behind one end that fix bar is provided with fixed pin, also, measuring scale horizontal positioned and fixation
The bottom alignment of pin；The bottom side of measuring scale is provided with graduation mark and scale value.
Further, mounting bracket, fix bar, drafting bar are connected by one in the connecting rod of T-shaped, even
One end of extension bar is provided with clamp nut.
Further, measuring scale is connected with fix bar by a screw rod.
Further, the upper end of mounting bracket is provided with a control-rod.
Further, clamp nut is butterfly nut, and screw rod is butterfly screw rod.
Compared with prior art, because measuring scale horizontal positioned back lower side edge aligns with the bottom of fixed pin,
And graduation mark and scale value are also all disposed within the bottom side of measuring scale, so after fix bar and drafting bar are opened,
The distance between the top of fixed pin and the top of drawing pen are exactly the radius of the circle to be drawn, the present invention
Advantage be：The circle of certain radius conveniently can be accurately drawn by measuring scale, while also can conveniently survey
Go out round radius.

Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the technical scheme in the embodiment of the present invention
It is clearly and completely described, it is clear that described embodiment is only a real part of the invention
Example is applied, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained on the premise of creative work is not made, belongs to
The scope of protection of the invention.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, but not as this hair
Bright restriction.
Fig. 1 is the structure chart of the compasses being convenient for measuring of offer in embodiments of the invention.As shown in figure 1,
A kind of compasses being convenient for measuring that the present embodiment is provided include：Mounting bracket 1, fix bar 2, drafting
Bar 3 and measuring scale 4；Wherein, fix bar 2 with draw bar 3 one end with mounting bracket 1
It is hinged；Fix bar 2 is provided with fixed pin 21 relative to the other end of mounting bracket 1, draws bar 3
Drawing pen 31 is provided with relative to the other end of mounting bracket 1；One end of measuring scale 4 is articulated with fix bar
Bottom edge and fixation behind 2 one end for being provided with fixed pin 21, also, the horizontal positioned of measuring scale 4
The bottom alignment of pin 21；The bottom side of measuring scale 4 is provided with graduation mark and scale value.
The present embodiment provide the compasses being convenient for measuring when in use, prime minister, by the level of measuring scale 4
Place, then, open fix bar 2 and draw bar 3, due to the horizontal positioned back lower side of measuring scale 4
Edge aligns with the bottom of fixed pin 21, and graduation mark and scale value are also all disposed within measuring scale 4
Bottom side, so when fix bar 2 and after draw bar 3 and open, the top of fixed pin 21 with draw
The distance between top of pen 31 is exactly the radius of the circle to be drawn.
As shown in figure 1, mounting bracket 1, fix bar 2, drafting bar 3 are in the company of T-shaped by one
Extension bar 11 is connected, and one end of connecting rod 11 is provided with clamp nut 12, can by clamp nut 12
Fixed with by mounting bracket 1, fix bar 2, the drafting three of bar 3, it is to avoid fix bar 2 draws bar 3
Rotating makes the size for determining change.
As shown in figure 1, measuring scale 4 is connected with fix bar 2 by a screw rod 41, by screw rod
41 can be fixed measuring scale 4, when need draw when can by measuring scale 4 rotate to fix bar
2 parallel positions, then, are fixed by screw rod 41, it is to avoid the influence of measuring scale 4 is drawn.
As shown in figure 1, the upper end of mounting bracket 1 is provided with a control-rod 13, by the energy of control-rod 13
More convenient control drawing pen 31 is center of circle rotation to fix pin 21.
Used as the preferred embodiments of the present invention, clamp nut 12 is butterfly nut, and screw rod 41 is butterfly
Butterfly screw rod, so rotates more laborsaving when clamp nut 12 and screw rod 41 is rotated.
These are only preferred embodiments of the present invention, not thereby limit embodiments of the present invention and
Protection domain, to those skilled in the art, should can appreciate that all utilization present invention say
The scheme obtained by equivalent and obvious change done by bright book and diagramatic content,
Should be comprising within the scope of the present invention.
