Abstract
The utility model belongs to a measuring appliance, particularly relates to a precise graduated cylinder for measuring volume of irregular solid body. The utility model describes a precise graduated cylinder, structural feature of which lies in a cup with big diameter and a small graduated cylinder marked with measuring scale; both the cup and the small graduated cylinder are provided with a conducting hole; a conducting tube is fixed between the conducting holes; the cup and the small graduated cylinder is connected with and communicated. Advantages of the utility model lies in small changesto existing graduated cylinder, same usage principle but wider application scope and higher measurement precision.
Description
Technical field
The utility model belongs to measuring appliance, relates in particular to the accurate graduated cylinder of measuring irregular solid volume.
Background technology
According to the Archimedes' principle people when measuring irregular solid volume, typically use the graduated cylinder that the proportion liquid littler than tested solid proportion is housed, in liquid, the liquid level difference of calculating tested solid immersion front and back then obtains the volume of tested solid with tested solid immersion.Existing graduated cylinder mostly is the monotubular structure, has the following disadvantages: promptly the graduated cylinder that sectional area is big can be measured the bigger tested solid of sectional area, but because of its graduated cylinder scale division value is big, reading out of true and cause measuring error big; Though thin graduated cylinder energy pin-point reading can't be measured the bigger tested solid of sectional area, usable range is little.
Summary of the invention
The utility model purpose is to overcome above-mentioned weak point of the prior art, and the accurate graduated cylinder that a kind of usable range is big, can accurately measure irregular solid volume is provided.
The technical scheme that the utility model adopted is a kind of accurate graduated cylinder, its structural feature is that it has a big Sheng cup of diameter and measures the little graduated cylinder of scale with indicating, on Sheng cup and little graduated cylinder, a via is arranged respectively, there is a conduction pipe to be fixed between the via, will contains cup and and tin be connected in a small amount and connect.
The utility model is only with two perforated containers, both are connected and connects with conduction pipe, changes for a short time, during batch process, also can adopt the mould one-shot forming, just makes it to have possessed the big advantage of big graduated cylinder usable range, has the measuring accuracy of little graduated cylinder simultaneously.
The purpose of this utility model can also be realized better by following approach.
Two shared identical bases of graduated cylinder.Easy to use, firm, be fit to the student and use.
The base of little graduated cylinder is lower than the base of big graduated cylinder.So little graduated cylinder can be made carefullyyer, makes it higher measuring accuracy, or wider measurement range is arranged, and the researcher who is suitable for having support bracket fastened laboratory and needs often to measure different volumes uses.
Scope.
In sum, advantage of the present utility model is with existing graduated cylinder change little, and use principle is constant, but usable range is wider, measuring accuracy is higher.

Embodiment
Below in conjunction with view the utility model is described in detail
Use principle: in use, 1) water is injected the bigger Sheng cup 1 of diameter, until having low amounts of water to overflow and flowing to a small amount of tube 2 the liquid level scale value of record a small amount of tube 2 from conduction pipe 3; 2) with tested solid immersion in big graduated cylinder 1, treat in a small amount tube 2 liquid level stabilizings after, record this moment is the liquid level scale value of tube 2 in a small amount; 3) the liquid level scale is poor before and after in the little graduated cylinder of root a tree name, can calculate the precise volumes of tested solid.
