[0013] 1. Compared with traditional densitometers, which can usually only be used for a certain specific inspection and can usually only be used to measure the density of a single group of objects, it is not convenient to intuitively observe the sinking and floating conditions of objects of different densities, and the measurement effect has limitations. By setting a first placement component that can be used to place multiple groups of transparent containers and a volume detection component corresponding to each group of transparent containers, it can be used to detect the volume of multiple different object samples at the same time, and by setting a connecting line, the relevant volume information detected by each group of volume detection components is transmitted to the data processing module for calculation and processing, so that the density of multiple different objects can be detected at the same time, which is faster and more efficient.

[0014] 2. By setting up a data processing module with a medium weight sensor and a data processor, it can not only be used for weighing, but also can perform formula calculations on the received volume data and mass data to obtain the density of the object, avoiding time-consuming and labor-intensive manual calculations. By setting up an adjustment component, it can be used to adjust the height of the volume detection component, so that corresponding adjustments can be made according to different usage requirements. By setting up a sleeve column with multiple groups of limit holes, the sleeve can be adjusted to different heights by fixing bolts in different limit holes, so that the measuring probe of the volume detection component can be adjusted to different positions according to different liquid level heights in the transparent container. By setting up a second detection component, it can be used to place the test object on it for weighing. By setting the placement box to a transparent material with scale lines, it can also be used to detect the volume of larger objects. The weight and volume obtained by weighing can be used to calculate the density of the object according to the density formula. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 5 In this embodiment, the adjustment component 3 includes a sleeve column 301, a work frame 302 and a bolt 305. The sleeve column 301 is symmetrically provided with four groups. The upper ends of the four groups of sleeve columns 301 are fixedly connected through the work frame 302. A plurality of through holes 303 for installing the volume detection component 4 are evenly distributed in the middle of the upper end of the work frame 302. By providing the through holes 303, the relevant detection structure of the volume detector 401 can be extended to the lower end for detection.

The lower end of the volume detector 401 is provided with a transmission rod 402 for transmitting detection information to the volume detector 401, and the lower end of the transmission rod 402 is provided with a measuring probe 403 for measuring the liquid volume.

[0027] When working, first place the density meter on a stable table, fill each set of transparent containers 105 with a proper amount of solution, and place the transparent containers 105 filled with the solution in the placement slot 102, so that the limit block 103 outside the placement slot 102 limits the outside of the transparent container 105;

[0028] Then, the measuring probe 403 of the volume detection component 4 is adjusted to a suitable position by the adjusting component 3. According to the height of the liquid level in the transparent container 105, after the measuring probe 403 is adjusted to a suitable position, the sleeve column 301 is fixed by adjusting the bolt 305 to the corresponding position of the limiting hole 304. The model of the volume detection component 4 is TLD950.

[0029] Then the initial volume of the solution is measured by the volume detection component 4, and the measurement data is transmitted to the data processing module 5 through the connecting line 7;

[0030] Then, the objects to be measured are placed on the placement box 201 in sequence, and their masses are weighed and recorded by the data processing module 5, and then the weighed objects are placed in the transparent container 105 in sequence;

[0031] The volume detection component 4 then measures the volume of the liquid after the item is placed, and transmits the data to the data processing module 5 through the connecting line 7 again;

[0032] Finally, the mass box volume of the object is automatically processed and calculated by the data processing module 5 using the density calculation formula to obtain the corresponding object density;

[0033] During the detection process, the relationship between the density of each object and the density of the solution, as well as the difference in density of each object itself, can also be roughly understood by observing the change in the liquid level in the transparent container 105;

[0034] When it is necessary to detect the density of a larger object, the object is weighed first, then an appropriate amount of solution is placed in the placement box 201, the volume of the solution is recorded by the scale line 202, and the object is placed in the liquid level difference obtained, which is the volume of the object. Finally, the density of the object is calculated using the density formula ρ=m / V.

[0035] Through the above steps, the staff first places the density meter on a stable desktop, puts an appropriate amount of solution into each group of transparent containers 105, places the transparent containers 105 filled with the solution into the placement slot 102, so that the limit block 103 outside the placement slot 102 limits the outside of the transparent container 105, and then adjusts the measuring probe 403 of the volume detection component 4 to a suitable position through the adjustment component 3. According to the height of the liquid level in the transparent container 105, after adjusting the measuring probe 403 to a suitable position, the bolt 305 is adjusted to the limit hole 304 at the corresponding position to fix the sleeve column 301, and then the volume detection component 4 is used to adjust the volume detection component 4. The initial volume of the solution is measured, and the measurement data is transmitted to the data processing module 5 through the connecting line 7. Then, the objects to be measured are placed on the placement box 201 in sequence, and their masses are weighed and recorded by the data processing module 5. Then, the weighed objects are placed in the transparent container 105 in sequence, and the volume detection component 4 is used to measure the volume of the liquid after the objects are placed. The data is transmitted to the data processing module 5 again through the connecting line 7. Finally, the mass and volume of the object obtained are automatically processed by the data processing module 5 using the density calculation formula ρ=m / V to obtain the corresponding object density. The first placement component 1 for placing multiple groups of transparent containers 105 and the volume detection component 4 corresponding to each group of transparent containers 105 can be used to detect the volumes of multiple different object samples at the same time, and the relevant volume information detected by each group of volume detection components 4 is transmitted to the data processing module 5 for calculation and processing by setting a connecting line 7, so that the density of multiple different objects can be detected at the same time, which is faster and more efficient. In the process of detection, the relationship between the density of each object and the density of the solution, as well as the difference in the density of each object itself can be roughly understood by observing the changes in the liquid level in the transparent container 105. Different test samples are placed in corresponding transparent containers 105 for synchronous testing, so that the sinking and floating conditions of different test objects can be clearly observed, which makes it easy to compare the densities of different objects intuitively. When it is necessary to test the density of a larger object, the object is weighed first, and then an appropriate amount of solution is placed in the placement box 201. The volume of the solution is recorded by the scale line 202, and the object is placed in the liquid level difference, which is the volume of the object. Finally, the density of the object is calculated using the density formula ρ=m / V. The density detector that can adjust the detection method according to different objects is more applicable, more convenient and practical.
