Abstract
The utility model relates to a measuring box for liquid refraction rate, which comprises a liquid filling box, one side of the liquid filling box is provided with a groove, the groove is provided with a slide channel, a bracket can be slide in the slide channel up and down, the top end of the bracket is pivoted with a laser flashlight; an inclined plate is connected fixedly at bottom corner of the liquid filling box close to the groove, an angle gauge is arranged on the inclined plate, the center position of the angle gauge is provided with a through-hole; the bottom end of the liquid filling box is provided with a graduation. When in use, the refraction rate of liquid can be read by utilizing the graduation marked at the bottom of the liquid filling box, different graduations are corresponding to different refraction rate (determined beforehand). The measuring box for liquid refraction rate has compliant principle, simple operation and is free of some complicated calculation processes and not affected by liquid fluctuation, no troubled measurement and calculation processes are needed and measurement result is accurate.
Description
Technical field
The utility model relates to a kind of survey instrument, especially a kind of convenient measuring refractive indexes of liquid case of surveying liquid refractivity.
The way that liquid folding rate is surveyed in the common physical test of technical background is that light is casted oblique rays in liquid level, obtains incident angle and refraction angle, calculates sine value separately again, brings formula into and calculates, and obtains refractive index, measure like this and be prone to error, and trouble very.
Summary of the invention
The purpose of this utility model has overcome above-mentioned said deficiency, provides a kind of measurement simple measuring refractive indexes of liquid case.
For achieving the above object, the utility model measuring refractive indexes of liquid case comprises liquid holding box, establishes groove in a side of liquid holding box, the groove inner slide, and support can slide up and down in slideway, and connect laser flashlight at the top of support axle; Consolidate swash plate at liquid holding box near the base angle of groove, and establish protractor, and establish open-work at the home position place of protractor at swash plate; Scale is established in bottom at liquid holding box.
After adopting said structure, during use, testing liquid is injected into liquid holding box, liquid level surpasses the height of open-work, and be lower than the height of liquid holding box, open laser flashlight, adjust the height of support and the angle of laser flashlight illumination, make illuminated line pass liquid from the open-work of swash plate by fixed angle, arrive the bottom of liquid holding groove again through liquid refracting, because the bottom of liquid holding box indicates scale, the refractive index value (having measured definite in advance) that different scales is corresponding different, when illuminated line is mapped on the scale of bottom surface, can read this liquid refractive index.
The utility model has the advantages that: meet principle, simple to operate, removed some complicated computation processes from, be not subjected to the fluctuation of liquid level to wait the influence of other factors, need not to carry out numerous and diverse measurements and calculations process, measurement result is more accurate.
