Description
Technical field
The present invention relates to the spectral instrument technical field of elemental analysis, is exactly specifically a kind of spectrophotometer index plate position control mechanism by carrying out amalyzing substances composition to the contrast of analyzed sample and standard specimen light intensity.
Background technology
Visible spectrophotometer can at black light---in visible spectral range, qualitative and quantitative analysis is done to sample material, it is one of spectrometric instrument that physics & chemistry lab is conventional, adopt advanced blazed grating monochromator, have wavelength accuracy high, monochromaticity is good, the advantages such as parasitic light is low, adopt microcomputer measurement system, τ-A conversion accuracy is high, and has adjustment 0% automatically and adjustment 100%, concentration factor setting, concentration readout, and serial data printer can be selected to carry out data-printing function.Be widely used in medical and health, clinical examination, biological chemistry, petrochemical complex, environmental protection, the departments such as quality control.
Spectrophotometric basic functional principle be the material in solution under the irradiation of light excites, create the absorption effect to light, the absorption of material to light has optionally.Various different material all has its respective absorption spectrum, therefore when certain monochromatic light is by solution, its energy will be weakened by absorbing, the concentration of the degree that luminous energy weakens and material has certain proportionate relationship, and spectrophotometer utilizes the contrast of this principle to analyzed sample and standard specimen light intensity to carry out amalyzing substances composition.
Spectrophotometer utilizes optical filter or grating etc. to select the monochromatic light needed, utilize grating to select the monochromatic spectrophotometer sensitivity requirement needed very high, but the existing spectrophotometer index plate of grating beam splitting that utilizes is all by manually or mechanical rotation regulating and controlling gear, but due to the sensitivity of grating beam splitting and accuracy requirement very high, like this by manually or mechanical rotation need back and forth repeatedly adjustment index plate could be allowed to rest on accurate location, greatly add the necessary working time of protractor, even there is alignment error, reduce measuring accuracy.
Summary of the invention
When the object of the invention is to utilize artificial adjustment scale for the existing spectrophotometer index plate utilizing grating beam splitting, complicated operation, need repeatedly to adjust back and forth, the technological deficiency that precision is not high, a kind of spectrophotometer index plate position control mechanism is provided, index plate can be made to rest on required gear accurately, reduce adjustment required time, effectively increase the precision measured.
Technical scheme
In order to realize above-mentioned technical purpose, the present invention designs a kind of spectrophotometer index plate position control mechanism, it comprises base, rotating shaft is contained on base, index plate is fixedly mounted in rotating shaft, it is characterized in that: the rotating shaft below described index plate is also fixedly equipped with gear control lever, gear control lever one end is fixed in rotating shaft, the other end stretches out index plate between left block and right block, gear control lever is parallel with index plate, left block and right block are arranged on base side, gear control lever can rotate with index plate, in rotation process, gear control lever stretch out index plate one end can respectively with left block and and right block adhesive.
Described gear control lever is ferrous metal, and left block and right block are permanent magnet.
Described rotating shaft is arranged in base intracavity and grating is housed.
Beneficial effect
The present invention utilizes permanent magnet as block, gear control lever can be made firmly to rest on the position of needs, thus make index plate steadily rest on suitable gear, avoid existing manual adjustment to need to adjust time-consuming defect back and forth, improve spectrophotometric measuring accuracy, whole mechanism structure is simple, only need do simple change and just can realize in existing mechanism, low cost.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is A place schematic diagram in accompanying drawing 1.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
Embodiment
As shown in figure 1 and 2, a kind of spectrophotometer index plate position control mechanism, it comprises base 1, rotating shaft 2 is contained on base 1, index plate 3 is fixedly mounted in rotating shaft 2, wherein, rotating shaft 2 below described index plate 3 is also fixedly equipped with gear control lever 4, gear control lever 4 one end is fixed in rotating shaft 2, the other end stretches out index plate 3 between left block 5 and right block 6, gear control lever 4 is parallel with index plate 3, left block 5 and right block 6 are arranged on base 1 side, gear control lever 4 can rotate with index plate 3, in rotation process, gear control lever 4 stretch out index plate 3 one end can respectively with left block 5 and and the adhesive of right block 6.
Described gear control lever 4 is ferrous metal, and left block 5 and right block 6 are permanent magnet.
Described rotating shaft 2 is arranged in base 1 inner chamber and grating is housed.
The present invention operationally, when index plate 3 rotates, when gear control lever 4 encounters left block 5 or right block 6 respectively, due to the effect of permanent magnet, gear control lever 4 can and left block 5 or right block 6 adhesive, thus make index plate 3 rest on the gear of needs accurately, do not need repeatedly to adjust and just can realize putting forward high-precision object. whole mechanism structure is simple, only need do simple change just can realize, low cost in existing mechanism.
