Abstract
The utility model relates to a measuring digital display device on a polarimeter, pertaining to the parts of the polarimeter. A bearing cap 8 and a bearing 2 are respectively fixedly connected with a shell 7, a worm 5 is rotatablely connected with the bearing 2, a worm wheel 6 is joggled with the worm, a handwheel 9 is fixedly connected with the worm 5, a raster component 4 is fixed on the worm 5, a photoelectric converter 3 is fixed on the shell 7 and a digital display component 1 is connected with the photoelectric converter 3 through a lead. The utility model has the advantages of high detection accuracy, easy operation and convenience for interfacing with the computer.
Description
Technical field
The utility model belongs to the parts of polarimeter.
Background technology
At present, polarimeter generally adopts the mode angles of display value of machine carousel, and this method is difficult to guarantee measuring accuracy, and operation is also inconvenient.
Summary of the invention
The new shape type of this practicality provides a kind of measurement digital display device of polarimeter, and it is low to have solved the prior art measuring accuracy, the problem of inconvenient operation.The concrete technical scheme that the utility model adopts is: bearing cap 8 is fixedlyed connected with housing 7 respectively with bearing 2, worm screw 5 is rotationally connected with this bearing 2, worm gear 6 and this worm mesh, handwheel 9 is fixedlyed connected with this worm screw 5, grating assembly 4 is fixed on this worm screw 5, photoelectric commutator 3 is fixed on the shell 7, and digital display assembly 1 and photoelectric commutator 3 are connected by lead.
Advantage of the present utility model is: the accuracy of detection height, and simple to operate, convenient with computer interface; Polaroid rotation when rotating handwheel when three separatrix of eyepiece field of view disappear, is pressed the reset button on the digital display assembly.After loading onto the test tube that is filled with testing liquid, rotate handwheel again, when three separatrix of eyepiece field of view disappear once more, read indicating value by the digital display assembly.
Description of drawings: accompanying drawing is the utility model structural representation.
