Description
Technical field
This utility model relates to detection technique field, wine trials room, a kind of electronic with illuminator
Lifting burette stand.
Background technology
During the detection of wine free sulur dioxide and total sulfur dioxide content, generally use direct iodine number
Method, because the method is fast and convenient, degree of accuracy is the highest.When iodimetric titration is for detecting the analysis of sulfur dioxide in white wine, its
Terminal is easier to judge；When detecting pink and red wine, especially red wine is because the color of wine is relatively deep, in titration eventually
It is difficult to see the color change of terminal during point so that endpoint error is bigger.Faced with this situation, coroner typically uses
Reduce sampling quantity or the method for dilute, and both approaches have impact on the accuracy of result the most to a certain extent.Additionally,
When burette reading, can with vertical folder on burette stand, or hand-held burette top without scale at.No matter use which kind of method
Reading, is desirable that burette keeps vertical, and during reading, sight line to flush with the concave meniscus of liquid level simultaneously, but both reading sides
Formula is the most relatively time-consuming arduously, and burette clamp is on burette stand during reading, and coroner must change certainly according to the height of liquid level
Oneself height of sighting line；Hand-held burette reading needs repeatedly burette to be taken off from burette stand.Meanwhile, burette is because of pipe
Mouth is narrow and small, easily makes volumetric solution spill, both wasted medicine, can pollute again burette outer wall when filling volumetric solution.
Summary of the invention
The purpose of this utility model is to provide a kind of electric up-down burette stand with illuminator, at wine dioxy
Titration end-point can be clearly judged during changing the detection of sulfur content, and can be with the device of motorized adjustment burette height.
The technical solution of the utility model is as follows: be made up of lamp box and lead screw gear two parts；Lamp box is built with electricity
Machine and the reductor driven thereof, reductor connects leading screw；Being also equipped with connecting circuit, LED lamp tube, upper surface is provided with glass surface；
Vertical beam is fixed on lamp box；Leading screw is arranged in vertical beam by location bearing, equipped with slide block on leading screw, slide block is fixed with titration
Pipe clamp, burette clamp stretches out from vertical beam slideway.
Further, the top of described vertical beam is mounted with separatory funnel runing rest, promising burette is placed above and adds
Volumetric solution separatory funnel.
Further, described lamp box is additionally provided with battery main switch, lamp box switch, slide block rises switch, slide block decline is opened
Close.
The utility model has the advantages that this device is the most simple to operate easy to use, and the accuracy of experiment can be improved,
There is the strongest practicality.
Accompanying drawing explanation
Fig. 1 is Facad structure schematic diagram of the present utility model
Fig. 2 is sectional view of the present utility model
Fig. 3 is schematic perspective view of the present utility model
In figure: 1 separatory funnel runing rest, 2 vertical beams, 3 leading screws, 4 slide blocks, 5 burette clamps, 6 lamp boxes, 7 power supplys are always opened
Pass, 8 lamp boxes switches, 9 slide blocks rise switch, 10 slide blocks decline switches, 11 glass surfaces, 12 connection circuit, 13 reductors, 14 LED
Fluorescent tube, 15 motors.
Detailed description of the invention:
The material that this practicality is newly used is the product of market public offering.
As shown in Figure 1, Figure 2, Figure 3 shows, lamp box 6 and lead screw gear two parts are constituted；Lamp box 6 built with motor 15 and
The reductor 13 driven, reductor 13 connects leading screw 3；Being also equipped with connecting circuit 12, LED lamp tube 14, upper surface is provided with glass
Face 11；Vertical beam is fixed on lamp box 6；Leading screw is arranged in vertical beam 2 by location bearing, equipped with slide block 4 on leading screw 3, leading screw 3,
Slide block 4 forms lead screw pair；Being fixed with burette clamp 5 on slide block 4, burette clamp 5 stretches out from vertical beam 2 slideway.
The top of described vertical beam 2 is mounted with separatory funnel runing rest 1, and separatory funnel has been placed above, can be direct
Volumetric solution is added for burette.
Battery main switch 7, lamp box switch 8, slide block rising switch (motor control) 9, slide block it is additionally provided with on described lamp box 6
Decline switch (motor control) 10.
Obviously, above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and
It it is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, in described above
On the basis of can also make other changes in different forms.Here cannot all of embodiment be given exhaustive.
Every belong to obvious change or variation that the technical solution of the utility model extended out still in of the present utility model
The row of protection domain.
