Description
Technical field
The utility model belongs to chemical analysis industry quality inspection technical field, and in particular to a kind of enhancing melting point apparatus sample
The device of brightness.
Background technique
One important indicator of chemical analysis industry quality inspection is exactly the purity of compound, and Accurate Determining compound
Fusing point is simple and quick effectively inexpensive one of the detection means for judging compound purity.During measuring fusing point, clearly
Compound incipient melting and fine melt phenomenon are observed in ground, are the key that read melting point data.Current measurement fusing point instrument is generally aobvious
The classes of compounds of micro- MELTING POINT TESTER, measurement is abundant, and color is various, and general light colour compound is surveyed in micro melting point
The phenomenon that being easier to observation incipient melting and fine melt on examination instrument；And for dark colour compound, since color can add in heating process
It is deep, it is more difficult the phenomenon that observing incipient melting and fine melt on micro melting point tester.The brightness of body surface depends on being radiated at
The color and intensity of light on object, red light, which is radiated at, enhances the brightness of red object, blue
Light, which is radiated at, enhances the brightness of blue object, green light be radiated on green body surface make it is green
Brightness enhancing of color object etc..Therefore, at present when measuring dark melting point compound, with the raising of temperature in continuous mode,
The color burn of compound can not clearly observe incipient melting and fine melt phenomenon and cause to be unable to asking for Accurate Determining melting point compound
Topic.
Utility model content
The purpose of this utility model is solved when measuring dark melting point compound, with the liter of temperature in continuous mode
Height, the color burn of compound can not clearly observe incipient melting and fine melt phenomenon and cause to be unable to Accurate Determining melting point compound
Problem provides a kind of device for enhancing the brightness of melting point apparatus sample.
To achieve the above object, the technical scheme adopted by the utility model is a kind of enhancing melting point apparatus sample brightness
Device, including cuboid container open at one end, in which: it further includes prism and light source, two rotation axis, the small cunning of knob
Wheel, belt；One end of each rotation axis is rotatablely connected with the middle and lower part of two inner sidewalls of container, each
The other end of rotation axis is connect with the both ends of the surface of prism respectively；And big pulley is equipped in the rotation axis for being located at left side, it is described
Knob be located in the inner left wall of container and be located at the top of big pulley, the truckle is located in the shaft of knob, and
The big pulley is connect with truckle by belt, rotates truckle by rotating knob, thus by the rotation of belt,
Big pulley and truckle is driven to rotate synchronously, to adjust the angle of prism；The light source is located at the top inner surface of container
Center, and the light source and the perpendicular middle part for being located at prism of prism；In the bottom of the cuboid container four
Angle is respectively provided with a circular aperture.
Preferably, the prism is the prism at 60 degree of angles of optical glass.
Preferably, the light source is the adjustable colourless LED light of luminous intensity.
Preferably, the radius ratio of the truckle and big pulley is 2:10 or 1:10.
Installed additional on melting point apparatus the present apparatus can with dark compound visible in detail in continuous mode incipient melting and fine melt
Phenomenon, and then melting point data is accurately read, achieve the purpose that accurately to measure fusing point.The prism of the utility model and big pulley are total
With fixing on the rotating shaft, truckle is fixed on knob, and truckle and big pulley pass through belt and rotate synchronously；It is revolved by rotation
Button rotates truckle to drive big pulley rotation prism, reaches the accurate angle for adjusting prism；According to measurement sample
Color, the angle that rotation knob adjusts prism enhance the brightness of sample, just so that the light of corresponding color is radiated on sample
In observation incipient melting and fine melt phenomenon；The brightness that light source can also be adjusted increases the intensity of incident light to enhance the brightness of sample, just
In observation incipient melting and fine melt phenomenon；Achieve the purpose that accurate recording melting point data；Therefore, compared with prior art, this is practical new
Type has enhancing sample brightness, improves observing effect, convenient for operation, at low cost, small in size, advantages of simple structure and simple, convenient for standard
Really measurement fusing point.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
As shown in Figure 1, a kind of device for enhancing the brightness of melting point apparatus sample described in the present embodiment, including open at one end rectangular
Bodily form container 1, in which: it further includes 3, two rotation axis 4 of prism 2 and light source at 60 degree of angles of optical glass, 6 truckle of knob
7, belt 8；One end of each rotation axis 4 is rotatablely connected with the middle and lower part of two inner sidewalls of container 1, each
The other end of a rotation axis 4 is connect with the both ends of the surface of prism 2 respectively；And big pulley is equipped in the rotation axis 4 for being located at left side
5, the knob 6 is located at the top in the inner left wall of container 1 and being located at big pulley 5, and the truckle 7 is located at knob 6
Shaft on, and the big pulley 5 and truckle 7 are connect by belt 8, rotate truckle 7 by rotating knob 6, from
