Part, fixture is installed in ensure that slit blade is moved in groove on slit pedestal, is divided in two micrometer caliper mounting holes
Micrometer caliper is not provided with, and one end of two micrometer calipers holds out against on two slit blades respectively, by adjusting spiral micrometer
Device, imposes slit blade pressure, to adjust the closing of slit, close.
In the above-mentioned technical solutions, on screw, screw is fixed on pedestal the torsion spring set.
In the above-mentioned technical solutions, on the extended line where the screw is located at the midpoint of groove length.
In the above-mentioned technical solutions, the screwed hole for fixed pedestal is provided with the pedestal.
In the above-mentioned technical solutions, one end of the fixture is arranged on slit blade top, the other end and is fixed on slit
On pedestal.
The beneficial effects of the invention are as follows：
1st, the present invention is in small prism spectrograph shoots spectrum experiment, by adjusting the width of slit, control spectral line into
The definition of picture and the width of spectral line lines, by adjusting the position of slit come leveling light path.
2nd, the present invention has component few, it is easy to the features such as dismantling, repair；Meanwhile, slit blade is upper and lower cross structure, is kept away
Exempt from slit blade to be damaged due to being extruded caused by faulty operation.

Specific embodiment
Below by specific embodiment, the invention will be further described, referring to Fig. 1-4：
A kind of new incidence slit device of small prism spectrograph, includes slit pedestal 1, slit pedestal 1 it is transversal
Face is rounded, and loophole 2 is centrally located on slit pedestal 1 and the groove 4 of slit blade 3 is placed.Wherein, loophole 2 is
Square hole；Groove 4 is rectangular recess.Loophole 2 is centrally positioned on groove 4.Spiral shell is respectively arranged with the two ends of groove 4
Rotation mircrometer gauge mounting hole 5, slit blade 3 is arranged in groove 4, and the adjacent one end of two slit blades 3 is upper and lower is staggered.
Abutting end specifically in two slit blades 3 be respectively provided with it is jagged, wherein a breach is above, another breach is located at down
Side.Positioning screw 6 is respectively arranged with two slit blades 3, torsion spring 7 is installed with the slit pedestal 1 of the side of groove 4, turned round
By being located in Positioning screw 6, opened in maximum when making two slit blades 3 under the effect of no external force respectively at the two ends of spring 7
State, fixture 8 is respectively arranged with the top of two slit blade 3, and fixture 8 is installed on slit pedestal 1 to ensure slit knife
Piece 3 is moved in groove 4, and micrometer caliper 9 is respectively arranged with two micrometer caliper mounting holes 5, two micrometer calipers 9
One end holds out against on two slit blades 3 respectively, by adjusting micrometer caliper 9, the pressure of slit blade 3 is imposed, to adjust slit
Close, close.
In the above-mentioned technical solutions, the torsion spring 7 is sleeved on screw 10, and screw is fixed on slit pedestal 1.Certainly,
Torsion spring 7 can also be sleeved on screw rod, and screw rod is screwed onto on slit pedestal 1, and the nut that is spirally connected on the screw rod of the top of torsion spring 7 is to turning round
Spring 7 is positioned.
In the above-mentioned technical solutions, on the extended line where the screw 10 is located at the midpoint of the length of groove 4.
In the above-mentioned technical solutions, the screwed hole 11 for fixed pedestal is provided with the slit pedestal 1.
In the above-mentioned technical solutions, one end of the fixture 8 be arranged on the top of slit blade 3, the other end be fixed on it is narrow
On seam pedestal 1.
Operation principle of the invention is：During measurement, micrometer caliper 9 is rotated, you can regulation slit width, and read
Number.Because slit blade 3 is upper and lower cross structure, it is sufficiently small that can adjust slit width, without because operational error, making
Slit blade is extruded and damaged.
Preferred embodiment of the invention described in detail above.It should be appreciated that one of ordinary skill in the art without
Need creative work just can make many modifications and variations with design of the invention.Therefore, all technologies in the art
Personnel are available by logical analysis, reasoning, or a limited experiment on the basis of existing technology under this invention's idea
Technical scheme, should all fall within the scope of protection of the present invention.
