Description

A kind of portable density measurement device

Technical field

The utility model relates to density of solid to measure field, in particular to a kind of portable density measurement device.

Background technique

During chemical analysis experiment, it is often necessary to measure the density of some solids, generally use Archimedes at present Solid density measuring method, but the instrument of existing density measurement or device construction are complicated, it is inconvenient for use, and generally require Special instrument measures, and expensive, Portable belt, does not bring inconvenience to practical application.

Summary of the invention

The purpose of the utility model is to provide a kind of portable density measurement devices easy to use to solve problem above. Purpose of the utility model is realized as follows:

A kind of portable density measurement device mainly includes pedestal 1, support rod 2, weighs needle 4 and large face plate 6；It is described Pedestal 1 is the round discus of thickness 0.7cm diameter 6cm；The support rod 2 is made of the iron wire of diameter 0.2cm, one end welding The other end curves hook and forms hook 3 on pedestal；The top for weighing needle 4 is welded the annulus that diameter is 0.8cm, circle Ring is made of diameter of the iron wire of 0.2cm, and the lower part for weighing needle 4 is made with diameter of 0.2cm iron wire, weighs needle bottom and wears into needle Pointed shape；The large face plate 6 is the small cylinder that the diameter made of the iron plate of 0.05cm thickness is a height of 1cm of 2cm, upper part weldering Then diameter is the annulus of 0.8cm, and bottom is uniform-distribution with the small sircle hole that diameter is 0.3cm；Needle 4 is weighed when use and is weighed Pallet 6 is hung on hook 3；This device cooperates assay balance to use, and structure is simple, cheap, easy to use.

A kind of portable density measurement device material is irony.

The principles of the present invention are calculated according to formula M=V ρ, and wherein M is quality, V is volume, ρ is density；It is first A fritter object under test first is taken with weighing needle or large face plate, weighing it, quality is denoted as M in air₁, then by object under test It is put into the solution of known density, such as distilled water, dehydrated alcohol etc. measures its mass M₂, remember that known fluid density is ρ_{It is known}, i.e., The density of test substance can be found out according to formula:

Detailed description of the invention:

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is the structural schematic diagram that the utility model weighs needle 4.

Fig. 3 is the structural schematic diagram of the utility model large face plate 6.

In figure, 1- pedestal, 2- support rod, 3- hook, 4- weighing needle, 5- link, 6- large face plate, 7- pallet.

Specific embodiment:

The utility model is described in further detail below in conjunction with the drawings and specific embodiments:

As shown in Figure 1, mainly including pedestal 1, support rod 2, weighing needle 4 and large face plate 6；

The pedestal 1 is the round discus of thickness 0.7cm diameter 6cm；The support rod 2 is the iron wire system of diameter 0.2cm At one end is welded on the other end on pedestal and curves hook formation hook 3；The top for weighing needle 4 is welded diameter and is The annulus 5 of 0.8cm, annulus 5 are made of diameter of the iron wire of 0.2cm, and weighing the lower part of needle with diameter is 0.2cm iron wire system At needlepoint form is worn into weighing needle bottom；The large face plate 6 is that the diameter made of the iron plate of 0.05cm thickness is 2cm a height of The small cylinder of 1cm, bottom are uniform-distribution with the small sircle hole that diameter is 0.3cm, and top is welded the annulus that diameter is 0.8cm； Needle 4 is weighed when use and large face plate 6 is hung on hook 3.

It is selected to weigh needle or large face plate according to the difference of measured and monitored the growth of standing timber matter, such as in measurement rubber, the quality such as wax are softer Substance selection weighs needle to measure, and directly with needle bundle is weighed on object under test, meausring apparatus is placed on assay balance, so Needle will be weighed afterwards and is hung over claims its aerial mass M on hook₁, a small beaker is then taken to hold the pure molten of some known densities Bundle is had object under test to weigh needle and is put into small beaker, and object under test is submerged known density by liquid, such as water, dehydrated alcohol Pure solution in, weigh its mass M₂.Finally it is calculated from the formula the density of testing liquid.

If object under test quality is harder can be replaced weighing needle use with large face plate.It should be noted that weighing every time Complete sample need to will weigh needle and large face plate wiped clean to reduce weighing error.
