[0036] The working principle of the portable pH meter calibration auxiliary mechanism is described in detail below.

[0037] like Figure 1-5As shown, when the pH meter probe 4 is limited in the fixed component 57, the transmission wheel 533 is driven to rotate by the motor 534, and the transmission wheel 533 drives the belt 532 to drive the pulley 531 to rotate and adjust, so that the pulley 531 drives the rotating rod 53 to rotate and adjust on the rotating seat 52, so that the position of the pH meter probe 4 can be adjusted, and the telescopic column 56 set on the back of the fixed component 57 cooperates with each other until the pH meter probe 4 is moved to the top of the solution to be measured, and the motor 551 drives the screw rod 55 to rotate in the threaded sleeve column 552, so that the threaded sleeve column 552 drives the moving block 553 to be raised and lowered in the fixed frame 54, thereby driving the pH meter probe 4 in the fixed component 57 to rise and fall along the adjustment plate 554 until the pH meter probe 4 is inserted into the solution for measurement and calibration, thereby achieving the function of convenient calibration, effectively automatically adjusting the pH meter probe 4 to calibrate the solution, facilitating the operation of workers, and effectively preventing the measurement solution from contaminating the staff.

The movable buffering property of the shock-absorbing column 511 can buffer the vibration generated by the operation of the adjustment mechanism, so that the pH meter probe 4 has stability when calibrating the solution, and the stability of the device is improved. The worker slides the pin 27 in the support frame 28 to pull the pin 27 out of the limit groove 26 set in the handle 25, thereby pulling the handle 25 to drive the limit insertion strip 24 to be pulled out of the through slot 23 set in the disassembly plate 22, so that the disassembly plate 22 is relaxed in the disassembly groove 21, and then separated, so that the support plate 5 is disassembled along the disassembly plate 22, so as to achieve the function of convenient disassembly, which is convenient for the staff to disassemble the adjustment mechanism later, and convenient for the staff to carry or store the pH meter equipment 1, thereby improving the practicality of the device.
