Description
Technical field
The utility model relates to density measuring equipment, refers to a kind of density rapid determination device of low density solid material particularly.
Background technology
The method of current mensuration materials of low density mainly contains two kinds, and object is cut into regular form measurement size by the first, then calculates volume, weighs, thus obtains density.Shortcoming is that the mode of such density measurement needs cutting object, is unsuitable for being obtain object density by the method for some shaping part.It two is the weight taking object, obtains bulking value with 3-D scanning, thus obtains density.Its deficiency is complex procedures, needs to use expensive equipment.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, provides a kind of density rapid determination device of low density solid material.
The technical solution of the utility model is: a kind of density rapid determination device of low density solid material, is characterized in that: comprise digital display electronic balance, graduated cylinder and to be fixed on object to be measured and quality is greater than the mass of article quality to be measured; Described graduated cylinder is placed on the weighing unit of digital display electronic balance, and graduated cylinder is greater than built with density the liquid that object density to be measured is less than mass density; Described liquid volume be greater than mass and object volume to be measured and; Described mass pulls object to be measured and sinks below liquid levels.
Further also comprise the connection chain be connected with object to be measured; The described connection chain other end is also slidably connected with it through mass.
One end that further described connection chain is connected with object to be measured is provided with the hook of fixing object to be measured.
Further described liquid is water.
Further described mass is lead.
The utility model structure is simple, utilizes the simple combination of common tool, solves the difficult problem that low-density object occurs in measuring process, have structure simple, easy to operate, measure advantage efficiently, there is great promotional value.

Fig. 2: mass and graduated cylinder syndeton schematic diagram in the utility model;
Wherein: 1-digital display electronic balance; 2-graduated cylinder; 3-the first connection chain; 4-mass; 5-liquid; 6-object to be measured; 7-hook; 8-the second connection chain; 9-fixed block.
Embodiment
As the density rapid determination device of Fig. 1 ~ 2 one kind of low density solid material, comprise digital display electronic balance 1, graduated cylinder 2 and to be fixed on object 6 to be measured and quality is greater than the mass 4 of object 6 quality to be measured.The object to be measured 6 of low density solid material is generally plastics or other lightweight materials, and density is generally less than the density of water, and density is greater than the density of water, can directly use digital display electronic balance 1, graduated cylinder 2 and water to carry out density measurement.
In use procedure, graduated cylinder 2 is placed on the weighing unit of digital display electronic balance 1, graduated cylinder 2 is greater than built with density the liquid 5 that object 6 density to be measured is less than mass 4 density, liquid 5 is generally water, the volume of water be greater than mass 4 and object to be measured 6 volume and, because in use, need mass 4 and object to be measured 6 all to submerge in water, therefore need the volume of water be greater than mass 4 and object to be measured 6 volume and.
In addition, second connection chain 8, second connection chain 8 one end being provided with connection between mass 4 and object to be measured 6 is welded on mass 4, and the other end is provided with hook 7, second connection chain 8 is wrapped on object 6 to be measured, and hooks the second connection chain 8 by hook 7 and fix object 6 to be measured.Ensure that object 6 to be measured can all be immersed in liquid 5 under the pulling of mass 4.
In addition, mass 4 is also welded with first connection chain 3, first connection chain 3 other end and is provided with fixed block 9, fixed block 9 is fixed on the bottom of graduated cylinder 2, and fixed block 9 mode be fixed on bottom graduated cylinder 2 can be that the mode by pasting is fixed.
Lead can be used in actual use procedure as mass 4.
During use: be filled into by liquid 5 in graduated cylinder 2, mass 4 is put in graduated cylinder, the volume recording liquid 5 in now graduated cylinder 2 is V
1, then graduated cylinder is put 2 and enter on the weighing unit of digital display electronic balance 1, allow digital display electronic balance 1 make zero.
Be wrapped in object 6 to be measured by the second connection chain 8, then hook a wherein ring with hook 7 and fix object 6 to be measured, object 6 to be measured is sunk in liquid 5, record now in graduated cylinder 2 liquid volume be V
2, now the reading of digital display electronic balance 1 is M, and the density that can calculate object 6 to be measured according to formula is:
Wherein: M---the weight of object 6 to be measured;
V
1---the volume of liquid 5 when object 6 to be measured is not put in graduated cylinder 2;
V
2---the volume of liquid 5 when object 6 to be measured is put in graduated cylinder 2;
ρ---the density of object 6 to be measured.
The utility model structure is simple, utilizes the simple combination of common tool, solves the difficult problem that low-density object occurs in measuring process, have structure simple, easy to operate, measure advantage efficiently, there is great promotional value.
