Abstract
The utility model belongs to a measuring appliance, in particular to a precision measuring cylinder used for measuring the volume of an irregular solid. The utility model is a precision measuring cylinder which is characterized in that the precision measuring cylinder is composed of two measuring cylinders with different inside diameters. The lower part of the opening ends of the two measuring cylinders is provided with a conducting pipe. The two measuring cylinders are connected and communicated by the conducting pipe. The small measuring cylinder is provided with measuring scales. The precision measuring cylinder has a small change on the basis of the existing measuring cylinder and the using principle is constant. The utility model has the advantages of wider range of use and higher accuracy in measurement.
Description
Technical field
The utility model belongs to measuring appliance, relates in particular to the Precision measuring cylinder of measuring irregular solid volume.
Background technology
People use the graduated cylinder that the liquid littler than solid proportion is housed to measure when measuring the volume of irregular solid usually, with tested solid immersion in liquid, calculate then tested solid immerse before and after graduated cylinder the liquid level difference and draw the volume of tested solid.Existing graduated cylinder mostly is the monotubular structure, has the following disadvantages: promptly the graduated cylinder that sectional area is bigger 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 the graduated cylinder energy pin-point reading that sectional area is less 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, provides a kind of usable range greatly, also can accurately measure the Precision measuring cylinder of irregular solid volume.
The technical scheme that the utility model adopted is a kind of Precision measuring cylinder, its structural feature is that it is made up of two different graduated cylinders of internal diameter, a conduction pipe is arranged below two graduated cylinder openends, and conduction pipe connects two graduated cylinders and connects, and little graduated cylinder is marked with the measurement scale.
The utility model is only with two graduated cylinder perforates, and 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, also 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.The graduated cylinder of this form is easy to use, and is firm, is fit to the student and uses.
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.
In sum, advantage of the present utility model is to do little change on the basis of existing graduated cylinder, and use principle is constant, but usable range is wider, measuring accuracy is higher.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment 1
Fig. 2 is the structural representation of the utility model embodiment 2
Wherein: 1 big graduated cylinder 2 is tube 3 conduction pipes 4 bases in a small amount
Embodiment
Below in conjunction with view the utility model is described in detail
Use principle: in use, 1) water is injected big graduated cylinder 1, 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.
