Technical field
The utility model relates to a kind of uniform meter, in particular, relates to a kind of protractor that do not adopted by light and electricity and gets final product the instrument of dividing any angle.
Background technology
In teaching and scientific research and production practices, often need some angles to carry out decile accurately.Be exactly the most simply angle carried out halve, the fourth class grades even number decile, and be difficult to carry out any non-zero natural number decile to a certain angle.In practical operation, the usual utilization hornwork of people carries out decile by numerical computations diagonal angle, and this method operation time error is larger.And during angle bisecting for some high-precision requirement, required instrument price is expensive, complicated operation, is not suitable for extensively promoting the use of.
Utility model content
The purpose of this utility model is just to provide a kind of simple to operate to solve the problem, high accuracy arbitrary angle in plane can be carried out the drawing tool of decile, with solving that tool operation is in the past simple but error is large or error is little but the present situation of complicated operation.
The utility model is achieved through the following technical solutions above-mentioned purpose: the arbitrarily angled uniform meter of photoelectricity, comprise top cover, transparent column shell, semitransparent reflecting film, pointer, rotating shaft, rotary laser transmitting terminal and rotate fixed axis, top cover and transparent column shell coaxially closely cooperate, rotating shaft be positioned at transparent column shell shaft core position and be fixed on top cover, rotating shaft concatenation pointer; Semitransparent reflecting film is embedded in transparent column housing center; Rotate fixed axis and be fixed on transparent column enclosure and tangent with the inwall of transparent column shell, rotate the relieved parallel with the axis direction of transparent column shell of fixed axis, rotary laser transmitting terminal is sleeved on and rotates on fixed axis, rotary laser transmitting terminal and rotation fixed axis coaxial cooperation; The line that transparent column enclosure bottom central point is positioned at the projection of the central point on transparent column enclosure bottom with rotation fixed axis forms the initial sideline of plane angle, and the line that transparent column enclosure bottom central point and pointer tip are positioned at the projection on transparent column enclosure bottom forms the whole sideline of plane angle.
Further, described pointer comprises hand rest, horizontal rotating arm and pointer head, the affixed rotating shaft of hand rest, and the bottom of hand rest is by horizontal rotating arm concatenation pointer head, and pointer head is positioned at the inwall also near transparent column shell inside transparent column shell.
Further, described pointer is provided with photo resistance.
Further, described rotary laser transmitting terminal is flexibly connected with rotation fixed axis, and rotary laser transmitting terminal can rotate around rotation fixed axis.
Technical conceive of the present utility model is: overlapped with two sidelines at the halved angle of plane angle by the initial sideline of the plane angle on photoelectricity angle equal divider, whole sideline.Rotate rotary laser transmitting terminal, make laser fall on pointer after semi-transparent semi-reflecting film for several times reflection, make photo resistance sense signal.Laser leaves luminous point on semi-transparent semi-reflecting film, controls the decile to halved angle by the number controlling luminous point.
The beneficial effects of the utility model are: the utility model structure is simple, production cost is low, carries out angle bisecting, drastically increase the precision of angle bisecting by the reflection that makes to use up, the means such as the photonasty of photo resistance and the light-gathering of lasing light emitter, and simple to operate easy to learn, be easy to promote.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, the arbitrarily angled uniform meter of photoelectricity, comprise top cover 1, transparent column shell 2, semitransparent reflecting film 3, pointer 4, rotating shaft 5, rotary laser transmitting terminal 6 and rotate fixed axis 7, top cover 1 and transparent column shell 2 coaxially closely cooperate, rotating shaft 5 be positioned at transparent column shell 2 shaft core position and be fixed on top cover 1, rotating shaft 5 concatenation pointer 4; Semitransparent reflecting film 3 is embedded in transparent column shell 2 central authorities; It is inner and tangent with the inwall of transparent column shell 2 that rotation fixed axis 7 is fixed on transparent column shell 2, rotate the relieved parallel with the axis direction of transparent column shell 2 of fixed axis 7, rotary laser transmitting terminal 6 is sleeved on and rotates on fixed axis 7, rotary laser transmitting terminal 6 and rotation fixed axis 7 coaxial cooperation; The line that transparent column shell 2 bottom center's point is positioned at the projection of the central point on transparent column shell 2 bottom surface with rotation fixed axis 7 forms the initial sideline of plane angle, and the line of the projection that transparent column shell 2 bottom center's point and pointer 4 tip are positioned on transparent column shell 2 bottom surface forms the whole sideline of plane angle.
Pointer 4 comprises hand rest, horizontal rotating arm and pointer head, the affixed rotating shaft 5 of hand rest, and the bottom of hand rest is by horizontal rotating arm concatenation pointer head, and pointer head is positioned at the inwall also near transparent column shell 2 inside transparent column shell 2.Rotating shaft 5 rotates and drives horizontal rotating arm to rotate around rotating shaft, thus drives pointer head to move in a circle around rotating shaft 5.
Pointer 4 is provided with photo resistance, for receiving the laser signal that rotary laser transmitting terminal 6 sends.
Rotary laser transmitting terminal 6 is flexibly connected with rotation fixed axis 7, and rotary laser transmitting terminal 6 can rotate around rotation fixed axis 7.
The utility model concrete operations flow process is: first overlapped with halved plane angle summit by the central point of rotating shaft 5 during use, make again the initial sideline of plane angle and halved angle while overlap, rotate rotating shaft 5 subsequently, the whole sideline of plane angle is overlapped with the another side at halved angle.Laser emission end 6 is rotated in now rotation, makes the laser beam of transmitting fall on pointer 4 after semi-transparent semi-reflecting film 3 for several times reflection, finally makes the photo resistance on pointer 4 sense signal, and is stopped the rotation by its signal control rotation Laser emission end 6.Laser leaves photoelectricity on semi-transparent semi-reflecting film, if luminous point quantity only has one, then measured angle is bisected; If luminous point quantity has two, then trisection measured angle; If luminous point quantity is N, then (N+1) decile measured angle.
Principle of the present utility model is as follows:
According to Fig. 3, O point is transparent column enclosure bottom central point, A point is the subpoint of laser emission point on transparent column enclosure bottom of rotary laser transmitting terminal 6, B point is the most advanced and sophisticated subpoint on transparent column enclosure bottom of pointer, and B point and C point are the subpoint of two pips on transparent column enclosure bottom of laser process.
Connect OC, OB.In circle O, OA=OB=OC=OD
∴ △ AOB, △ BOC, △ COD is isosceles triangle
According to concave mirror principle, known
∠OBA＝∠OBC,∠OCB＝∠OCD
That is: ∠ OAB=∠ OBA=∠ OBC=∠ OCB=∠ OCD=∠ ODC
∴ ∠ AOB=∠ BOC=∠ COD, i.e. OB, OC three equal parts ∠ AOD
When pip be any many time, proving by the same methods OB, OC, OD, OE ... any decile ∠ AOD.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technical scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
