Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
As shown in Figure 1, 2, a kind of planetarium passes through including support plate 1, the planetarium ontology 2 being arranged in support plate 1
What planetarium ontology 2 can be convenient projects the various astrology, and planetarium ontology 2 includes northern fixed star ball 3, southern fixed star ball 4, is located at north
Central transmission part 5 between fixed star ball 3 and southern fixed star ball 4 is provided in spherical shape projection chamber interior walls projection in support plate 1
The auxiliary line laser projecting apparatus 6 of ground diameter astragal is provided on central transmission part 5 in spherical shape projection chamber interior walls projection equator
The auxiliary line laser projecting apparatus 6 of collar.
As shown in Figure 2, wherein auxiliary line laser projecting apparatus 6 includes being separately fixed at central transmission part 5 and support plate 1
On fixing seat 611 be fixed in fixing seat 611 for project the laser 612 of collar or equator collar, laser 612
Including light source with can be under light source irradiation in spherical projection chamber interior walls projection ground collar or the camera lens 6121 of equator collar, use
Different camera lenses 6121, which can be replaced, can project the auxiliary line of needs.
In use, simulating the astrology by planetarium ontology 2, pass through the projection of the laser 612 ground collar being located in support plate 1
Auxiliary line projects equator collar auxiliary line by the laser 612 on centrally located running part 5.
As shown in Figure 3,4, wherein fixation hole 7 is provided in fixing seat 611, fixation hole 7 is inserted into for laser 612, and
It is provided with the notch 8 being connected to fixation hole 7 in fixing seat 611, is provided in the opening of notch 8 big for adjusting notch 8
Small fastening bolt 9 can make the openings of sizes of notch 8 change, on laser 612 by adjusting fastening bolt 9
Prominent 612 surface of laser is provided with positioning protrusion 12, is provided on the inner wall of fixation hole 7 and determines with what positioning protrusion 12 cooperated
Position slot 13, locating slot 13 are located on the inner wall of fixation hole 7 and in 7 ends of fixation hole.
When needing replacing laser 612, adjusts fastening bolt 9 and opening is become larger, fixation hole 7 will become larger at this time, laser
Device 612 can be extracted out from fixation hole 7, the laser 612 then more renewed, later, new laser 612 is inserted into fixation hole 7
In, and positioning protrusion 12 is just inserted into locating slot 13, make becoming smaller for fixation hole 7 by tightening fastening bolt 9 later,
Laser 612 will be locked in fixation hole 7 at this time, due to there is the limit of locating slot 13 Yu positioning protrusion 12 after replacement,
The position of laser 612 can be consistent before with replacement, and the auxiliary line that laser 612 projects after replacement is accurate, auxiliary line
It is less prone to location error.
As shown in Figure 4,5, wherein when in order to avoid being fixed on laser 612 in fixing seat 611, so that laser 612
It is impaired, fixation hole 7 is provided with several fixing grooves 10 in fixation hole 7, rubber strip 11 is provided in fixing groove 10, in order to
It avoids rubber strip 11 from falling from fixing groove 10, is provided with glue between fixing groove 10 and rubber strip 11, when 612, laser
Since 11 surface of rubber strip is softer when in fixation hole 7, laser 612 and rubber strip 11 will be not easy to make laser when contacting

Wherein, in order to laser 612 be made to be secured firmly in fixation hole 7 when adjusting fastening bolt 9, so that lacking
Laser 612 and fixation hole 7 are interference fitted when the two sidewalls fitting of mouth 8, at this point, after laser 612 is fixed in fixation hole 7
Fastening bolt 9 is tightened, so that 8 two sidewalls of notch are bonded, laser 612 will be firmly fixed later, and be not likely to produce fastening spiral shell
Laser 612 is pressed from both sides bad situation when twisting too tight by bolt 9.
As shown in Figure 3,4, wherein in order to enable observer intuitively sees and understands mean sun, be fixed on central biography
It is provided in fixing seat 611 on dynamic part 5 for projecting the mean sun mean sun projector 14 in spherical shape projection chamber interior walls, is put down
The sun projector 14 can be projected in spherical shape projection chamber interior walls for simulating mean sun annular aperture.
The mean sun or fictitious sun is an imaginary celestial body, its annual and true sun is red in day simultaneously from the first point of Aries
It travels at the uniform speed eastwards on road from west, this speed is equivalent to the average speed that true sun is run on ecliptic, last and true sun
Return to the first point of Aries simultaneously, but due to it is mean sun be the celestial body of illusion, some observer's indigestions, so in order to enable
Observer intuitively sees and understands mean sun, and the mean sun projector 14 is provided in fixing seat 611, passes through mean sun projection
Device 14 is directly cast out mean sun, directly observes its movement, simultaneously because mean sun need to move in use, and
The track that it is moved is consistent with the motion profile of fixing seat 611 on central transmission part 5, therefore the mean sun projector 14 is consolidated
It is scheduled in the fixing seat 611 on central transmission part 5.
As shown in Figure 3,4, wherein it is provided with supported hole 15 in the fixing seat 611 being fixed on central transmission part 5,
The support column 16 being threadedly engaged with supported hole 15 is provided on the mean sun projector 14, it can be with by supported hole 15 and support column 16
Easily the mean sun projector 14 is installed.
The above is only the exemplary embodiment of the utility model, the protection model rather than limited the present invention
It encloses, the protection scope of the utility model is determined by the attached claims.
