Medicine, petrochemical industry, modern agriculture, metallurgy, geological prospecting, ecological environment and national defense and military etc..Due to its important application value,
Spectrometer has had been to be concerned by more and more people, and it has turned into the important component of Modern Scientific Instruments.
Spectrometer is before being detected, it is necessary to carry out light modulation adjustment.Existing spectrometer, grating are located in spectrometer housing
Portion, it is necessary to which the housing for opening spectrometer is adjusted to grating during adjustment, after adjustment, ressembled completely by housing,
In assembling process, because housing is in the presence of the fasteners such as screw, it may occur that micro deformation, the deformation frequently can lead to
The angle of grating still has certain error after housing assembles.
Utility model content
The purpose of this utility model is above mentioned problem be present for existing technology, it is proposed that a kind of spectrometer, the spectrum
Grating is arranged in spectrometer housing by instrument by rotating shaft, and is provided with adjustment seat in hull outside, can be outside by adjustment seat
Portion adjusts grating, simple in construction, easy to adjust, and light modulation accuracy is high.
The purpose of this utility model can be realized by following technical proposal：
A kind of spectrometer, including both ends have the housing of opening, are arranged on grating in housing, set in shell one end opening
And the detector seat of shell one end opening is closed, the optical fiber and detector being fixed on detector seat, it is characterised in that described
Grating is arranged on housing by rotating shaft, adjustment seat is provided with another end opening of the housing, the adjustment seat closes
Another end opening of housing, adjusting screw is provided with the adjustment seat, and the adjusting screw is extend into housing and the light
Grid to against to promote grating along the axis of rotation adjust grating angles.
Preferably, sealant sealing is provided between the adjustment seat and housing.
Preferably, being provided with case on the housing, the case is used for fixing circuit board.
Preferably, protrusion is fixed in mounting seat formed with mounting seat, the optical fiber on the inside of the detector seat.
Preferably, it is provided with fixing screws in the adjustment seat.
Compared with prior art, the utility model has advantages below using said structure and method：
Grating is arranged in rotating shaft by the utility model, and adjustment seat is provided with spectrometer shell, passes through adjustment seat
Grating is promoted to carry out micro rotation along rotating shaft to adjust light path, it is simple in construction, while need not open spectrometer in regulation
Housing is i.e. adjustable, easy to adjust, and when avoiding assembling spectrometer housing, it is caused by mistake that spectrometer housing produces micro deformation
Difference.

Embodiment
It is specific embodiment of the utility model and with reference to accompanying drawing below, the technical solution of the utility model is made further
Description, but the utility model is not limited to these embodiments.
As depicted in figs. 1 and 2, according to an embodiment of the present utility model, a kind of spectrometer is shown, including with opening
Spectrometer housing 10, the detector seat 30 being arranged in the one end open of housing 10, be arranged on 10 another end opening of housing
Adjustment seat 20, and it is arranged on the grating inside housing 10.Wherein, grating is spindle rotationally arranged in housing 10 by rotating shaft 70
Interior, adjustment seat 20 and detector seat 30 each seal up the both ends open of housing 10 respectively, and regulation spiral shell is provided with adjustment seat 20
Nail 21 and fixing screws 22, by adjusting seat stator housing 10, adjusting screw 21 is extend into housing 10 fixing screws 22
Portion and with grating against, by adjust adjusting screw 21 can drive grating carry out certain angle rotation, with this come reach adjust
Program.
As shown in 3 figures, in the present embodiment, housing 10 is into case shape, and rotating shaft 70 is arranged on the madial wall of housing 10, grating
It is arranged in rotating shaft 70, the outside of grating is provided with retainer plate 60, is easy to grating to be attached with rotating shaft 70.The snapping of adjustment seat 20
Fix on the housing 10, sealed between adjustment seat 20 and housing 10 using fluid sealant, make it have better seal effect.
Adjusting screw 21 in adjustment seat 20 is resisted against on retainer plate 60, ensures that grating will not be because of tune while regulation is not influenceed
Save the extruding of screw 21 and produce scratch or other damages.
The top of housing 10 is provided with case 40, and case 40 is used for fixing circuit board 50 so that the profile of whole spectrometer
Construction is more attractive in appearance, and structure is more simplified.
Optical fiber 32 is arranged on detector seat 30, and the inner side of detector seat 30 protrusion is formed with mounting seat 31, in order to install
Optical fiber 32.
The utility model at work, is adjusted to grating by adjusting adjusting screw 21 outside housing 10, adjusted
Process is simple, time-consuming short, improves the service efficiency of spectrometer, it also avoid simultaneously, and existing spectrometer is opening housing 10
After cap, when cap assembles with housing 10, the two is mutually extruded, and causes the sheet material for loading spectrometer that micro deformation, the shape occurs
Change cause light path angle to change, produce detection error the problem of.
