Abstract
The utility model discloses a kind of partition-type sealing optical path analysis instrument, optical path analysis instrument includes main body and closure, sample bin is offered in main body, sample bin bottom is fixedly installed diaphragm seal, optical path area is provided with below diaphragm seal, it is provided with light inlet and light-emitting window in optical path area, the focus of the center line of light inlet and light-emitting window is the sample detection point in sample bin.The utility model is fixed with diaphragm seal in sample bin and separates the light path detection part of sample bin and inflation area, so that inflation area is all the time filled with gas, when changing sample, open closure, due to there is the presence of diaphragm seal, so that the gas of inflation area will not be revealed, the gas being filled with is caused to waste the consumption for reducing gas during so as to avoid changing sample, reduce testing cost.
Description
Technical field
The utility model discloses a kind of optical analyzer, particularly a kind of partition-type sealing optical path analysis instrument, belongs to table
Surface analysis Instrument technology field.
Background technology
Spectrum analysis is the conventional analysis means of body surface detection, i.e., is irradiated to detected sample table by peculiar spectrum
Face, by the spectrum analysis of reflected light, so as to obtain the surface parameter of detected sample.When some article surfaces are analyzed, to atmosphere
It is higher to enclose requirement, it usually needs be filled with special gas in the light path of detected sample（Such as：Helium etc.）, to complete to detect, by
Larger in sample bin volume, when changing sample every time, when opening closure, can then enter air in sample bin, detect again
When, then sample bin is evacuated, is then filled with gas again, can thus wasted many special gas, cause material
Waste.
The content of the invention
The shortcomings that for the waste of gas can be caused during spectrum analysis of the prior art mentioned above, the utility model
A kind of partition-type sealing optical path analysis instrument is provided, it is fixed with diaphragm seal by sample bin and light path test section in sample bin
Separate, the gas that is filled with is caused to waste during avoiding changing sample.
The utility model solves the technical scheme that its technical problem uses：A kind of partition-type seals optical path analysis instrument,
Optical path analysis instrument includes main body and closure, offers sample bin in main body, sample bin bottom is fixedly installed diaphragm seal, close
Optical path area is provided with below sealer, is provided with light inlet and light-emitting window in optical path area, Jiao of the center line of light inlet and light-emitting window
Point is the sample detection point in sample bin.
The technical scheme that the utility model solves the use of its technical problem further comprises：
Described light inlet and the central axis of light-emitting window are set.
Described body top is provided with the first sealing ring mounting groove, and it is close to be fixedly installed first in the first sealing ring mounting groove
Seal, the first sealing ring are arranged between main body and closure.
The first described sealing ring mounting groove cross section is trapezoidal.
Described sample bin bottom offers the second sealing ring mounting groove, and is fixedly installed in the second sealing ring mounting groove
Two sealing rings.
The second described sealing ring mounting groove cross section is trapezoidal.
Described diaphragm seal uses polyester film.
The beneficial effects of the utility model are：The utility model is fixed with diaphragm seal by sample bin and filled in sample bin
The light path detection part in gas region separates so that and inflation area filled with gas, when changing sample, opens closure all the time, due to
There is the presence of diaphragm seal so that the gas of inflation area will not be revealed, and the gas that is filled be made during so as to avoid changing sample
Into the consumption for wasting reduction gas, testing cost is reduced.
The utility model is described further below in conjunction with the drawings and specific embodiments.
Brief description of the drawings
Fig. 1 is the utility model section structural representation.
In figure, 1- main bodys, 2- closures, 3- sample bins, 4- diaphragm seals, 5- samples, 6- light inlets, 7- light-emitting windows, 8- fills
Gas region, the sealing rings of 9- first, the sealing rings of 10- second.
Embodiment
The present embodiment is the utility model preferred embodiment, and other all its principle and basic structure are identical with the present embodiment
Or it is approximate, within scope of protection of the utility model.
Accompanying drawing 1 is refer to, the utility model mainly includes main body 1 and closure 2, is offered in main body 1 for receiving sample
The sample bin 3 of product 5, the bottom of sample bin 3 are fixedly installed diaphragm seal 4, will be separated inside sample bin 3, a part be for
The region of sample 5 is placed, another part is optical path area, filled with gas in optical path area, in the present embodiment, is defined as filling
Gas region 8, in the present embodiment, optical path area includes light inlet 6 and light-emitting window 7, and the center line of light inlet 6 and light-emitting window 7 hangs down
Straight to set, the focus of the center line of light inlet 6 and light-emitting window 7 is the sample detection point in sample bin 3.
In the present embodiment, the top of main body 1 is provided with the first sealing ring mounting groove, and the first sealing ring mounting groove cross section is in ladder
Shape, is fixedly installed the first sealing ring 9 in the first sealing ring mounting groove, the first sealing ring 9 be arranged on main body 1 and closure 2 it

In the present embodiment, the second sealing ring mounting groove, the second sealing ring mounting groove cross section are offered in the bottom of sample bin 3
It is trapezoidal, the second sealing ring 10 is fixedly installed in the second sealing ring mounting groove, because the second sealing ring mounting groove is trapezoidal, institute
There is the second sealing ring to be fixedly mounted on when mounted by self-deformation in the second sealing ring mounting groove, pass through the second sealing ring
10 push down diaphragm seal 4, and diaphragm seal 4 is deployed and is fixed on the bottom of sample bin 3.
In the present embodiment, diaphragm seal 4 can use the materials such as polyester film to be made.
The utility model when in use, open closure 2, test point opening position sample 5 being placed in sample bin 3,
Gas is filled with inflation area 8, sample 5 is detected；After the completion of detection, closure 2 is opened, sample 5 is changed, by
It will not cause to reveal when the gas in the presence of diaphragm seal 4, inflation area 8 is changing sample.
The utility model be fixed with sample bin diaphragm seal by the light path detection part of sample bin and inflation area every
Open so that inflation area filled with gas, when changing sample, opens closure, due to there is the presence of diaphragm seal so that inflation all the time
The gas in region will not be revealed, and the gas that is filled be caused to waste the consumption for reducing gas, drop during so as to avoid changing sample
Low testing cost.
