Abstract
The utility model discloses a device for using an electric balance to measure volume and density of small articles lower than specific-liquid density. The technical proposal is as follows: the utility model comprises an electric balance, a thin wire the weight of which does not act on a measured article bearing body of the electric balance is suspended above the bearing body of the electric balance, the lower end of the thin wire is connected with a supporting carrier provided with a cover, the cover and/or the supporting carrier is provided with a through hole. The utility model can measure the quality (W<object>) of a small article and the quality (W) of the discharged liquid when the small article is completely immersed in the liquid with defined density; the volume (V<discharge> is equal to V<object> and W/rho<liquid> ) and the density (rho<object> is equal to rho<liquid>W<object>t/W) of the small article can be evaluated by using that W is equal to F float/g and F float is equal to rho<liquid>gV<discharge>. The device has a simple structure, convenient operation and high measurement accuracy.
Description
Technical field
The utility model relates to the device of a kind of measurement volumes and density, relates in particular to a kind ofly to utilize the electronic balance measurement to be lower than than the little article volume of liquid density and the device of density.
Background technology
At present, experiment is generally adopted the graduated cylinder drainage with the volume of measuring little article, utilize the difference of reading of liquid in the graduated cylinder that adds article to be measured front and back, be the volume of the article of surveying, because the cylinder scale precision is low, the subjective influence of people's observation is bigger, and the reading accuracy of naked eyes is limited, and therefore the measuring error of this method is big, precision is not high.
Summary of the invention
The technical assignment of the invention is at the existing in prior technology shortcoming, and provides a kind of high-acruracy survey to be lower than technical scheme than the device of the little article volume of liquid density and density, and this apparatus structure is simple, handled easily, measuring accuracy height.
The technical solution of the utility model is to realize by following technical measures, it comprises electronic balance, the overhung of described electronic balance supporting body has weight not act on electronic balance to measure fine rule on the article supporting body, the lower end of fine rule is connected with the holder carrier that has lid, and lid and/or holder carrier are provided with through hole.
Connect by double buckle between above-mentioned lid and the holder carrier.This fit system is simple and convenient, after the object of little density being put into the holder carrier, lid and holder carrier is fastened.Can prevent like this that object is floating goes out to hold in the palm carrier.
Described line can be by other member supports such as supports, and its weight does not act on the balance, for easy to use, improves measuring accuracy, and the diameter of fine rule is 1 micron～20 microns a waterline.Electronic balance is provided with weight and does not act on the sealed cover body that has switching door on the supporting body, be fixed with fine rule on the upper wall of cover body, but the side of cover body is provided with the door of folding.Simplify the structure like this, can in the process of measuring, avoid the interference of extraneous factor as far as possible, for example gentle breeze etc.
The diameter of described fine rule can be tried one's best carefully, specifically can adopt the waterline of 1 micron～20 microns of diameters.
Be placed with container on the supporting body of described electronic balance, the holder carrier of fine rule lower end is arranged in container.Can fill in the container and determine density liquid, volume of a container can be placed in the cover body satisfied, satisfy under other prerequisite of measuring pacing items big as far as possible, like this, after placing article to be measured on the holder carrier, the liquid level in the container rises, when line carefully after to a certain degree, because the volume of container is bigger, the volume of fine rule draining can be ignored after liquid level rose.

Embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by an embodiment.
As Fig. 1: the utility model comprises the electronic balance 2 that has supporting body 9, and electronic balance 2 is provided with weight and does not act on cover body 4 on the supporting body 9, but at least one side in the left and right side of cover body 4 is provided with the door 3 of folding.Be fixed with fine rule 5 on the upper wall of cover body 4, the lower end of fine rule 5 is connected with uncovered holder carrier 7, and holder carrier 7 is provided with the lid 12 that is mated, and lid 12 and holder carrier 7 are provided with a plurality of through holes, and the interior liquid of holder carrier and container is communicated.The diameter of fine rule 5 is 1 micron～20 microns, and electronic balance 2 has leg 1, operational zone 10 and viewing area 11.
It is as follows to utilize the utility model to measure volume and its concrete measuring process of density of little article:
1.. at first on the electronic balance 2 of high measurement accuracy, measure the quality W of little article 6
Thing
2.. the container 8 that will fill the known density normal fluid is placed on the article supporting body 9 to be measured of electronic balance 2 of high measurement accuracy, get fine rule 5, its lower end is connected with holder carrier 7, and the holder carrier 7 that will have a lid 12 is immersed in the liquid in the container 8 fully, the zero clearing or the W that takes reading
1, the weight of the holder carrier 7 of this moment fine rule 5 and connection thereof does not all act on the electronic balance 2 (to be annotated: W
1Be immersed in the quality of 5 the discharge opeing bodies of part fine rule in the liquid for holder carrier 7);
3.. little article 6 to be measured are put into holder carrier 7, and fasten lid 12, little article 6 are immersed in the liquid, the holder carrier 7 of this moment fine rule 5 and connection thereof, the weight of the article 6 on the holder carrier 7 all do not act on the electronic balance 2, and W takes reading
2(annotate: little article 6 should soak the enough time at this liquid before putting into, so that it absorbs liquid to saturated, take out and dry lip-deep liquid, measure in the holder carrier 7 of in time packing into, and attention can not spill liquid)
4.. adopt formula W=W
2-W

ThingAnd density p
Thing
This method is simple to operate, if the precision of electronic balance is 0.1mg, the volume accuracy that then uses this method to measure little article can reach 0.1mm
3, the corresponding precision of surveying little article density can reach 0.1mg/cm
3, this shows that the utility model measuring accuracy is higher.
