Description

Technical Field

[0001] The utility model relates to the technical field of acidity meters, in particular to a portable acidity meter. Background Art

[0002] Acid-base meter, also known as pH meter, is an instrument used to measure the pH value of a solution. It works on the principle of a galvanic cell. The electromotive force between the two electrodes of a galvanic cell is based on the Nernst law, which is related to both the properties of the electrodes themselves and the concentration of hydrogen ions in the solution. There is a corresponding relationship between the electromotive force of the galvanic cell and the hydrogen ion concentration, and the negative logarithm of the hydrogen ion concentration is the pH value. Acid-base meter is a common analytical instrument, widely used in agriculture, environmental protection, industry and other fields. Soil pH is one of the important basic properties of soil. Factors such as the temperature of the solution to be tested and the ionic strength should be considered during the pH determination process.

[0019] The technical solution of the utility model is further described below through the accompanying drawings and embodiments.

[0020] Example

[0021] like Figure 1-2 As shown, a portable acidity meter comprises a body 1 and a probe 2. A handle 3 is provided on one side of the body 1, and the handle 3 is convenient for the user to carry the acidity meter as a whole. A storage slot 4 is provided on the body 1, and a dust cover 5 is provided on one side of the storage slot 4. The dust cover 5 can provide dust protection for the storage slot 4 and its internal components. A magnetic block 6 is provided at one end of the storage slot 4, and the other end of the storage slot 4 is connected to the first support plate 7 through a first rotating shaft with a torsion spring. The first support plate 7 is provided with an iron sheet corresponding to the magnetic block 6. The magnetic block 6 and the iron sheet can be used in combination to fix the first support plate 7 and prevent the first support plate 7 from bouncing up under the action of the torsion spring. A slot is provided on the outer side of the first support plate 7, and the top of the first support plate 7 is connected to the second support plate 8 through a second rotating shaft. The second support plate 8 is provided with a probe adapter slot 9 and a hinge rod 10, and the hinge rod 10 is adapted to the slot. The hinge rod 10 and the slot can be used in combination to support and fix the second support plate 8. The slot is located in the clearance groove 11 on the first support plate 7, and the clearance groove 11 is adapted to the structure of the second support plate 8. The clearance groove 11 can accommodate the second support plate 8 and prevent the second support plate 8 from tilting and warping due to the existence of the hinge rod 10.

[0022] Two guide grooves 12 are arranged opposite to each other on the inner wall of the probe adapter groove 9, and a circular groove 13 is arranged in the middle of the guide groove 12. A sliding sleeve 14 is arranged between the two guide grooves 12, and the sliders on both sides of the sliding sleeve 14 are adapted to the structure of the guide groove 12. The guide groove 12 can make the slider slide therein so as to guide the sliding sleeve 14. The length of the slider is less than the diameter of the circular cross section of the circular groove 13, and the slider can rotate in the circular groove 13 so as to make the sliding sleeve 14 flip in the probe adapter groove 9. The probe 2 is inserted into the sliding sleeve 14, and a connecting sleeve 15 is fixedly connected to the outer wall of the probe 2, and the connecting sleeve 15 is overlapped on the top of the sliding sleeve 14. The coordinated use of the connecting sleeve 15 and the sliding sleeve 14 can facilitate the disassembly and assembly of the probe 2.

[0023] When in use, pull the first support plate 7 to separate the magnetic block 6 and the iron sheet. At this time, the first support plate 7 can maintain a vertical state under the action of the torsion spring, and then insert the end of the hinged rod 10 into the slot to fix the second support plate 8, flip the sliding sleeve 14 so that the sliders on both sides of the sliding sleeve 14 move into the guide groove 12, and then adjust the sliding sleeve 14 with the probe 2 to a suitable position in the guide groove 12, and finally use the probe 2 to perform acidity measurement; after the measurement is completed, wipe the probe 2, and then push the sliding sleeve 14 back into the circular groove 13, flip the sliding sleeve 14 so that the sliding sleeve 14 with the probe 2 is stored in the probe adapter groove 9, move the hinged rod 10 out of the slot, and put the hinged rod 10 and the second support plate 8 into the yield groove 11, and then push to the first support plate 7 until the magnetic block 6 absorbs the iron sheet, and finally cover the dust cover 5, so that the storage of the probe 2 is completed.

[0024] Therefore, the utility model adopts the portable acidity meter of the above structure, which simplifies the support and installation process of the probe and can also realize the storage and protection of the probe.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
