[0002] Acidity meter, also known as pH meter, acid-base detector, is an instrument that uses pH indicator electrode to determine the pH value of solution by potentiometric method. It is a precision electronic millivoltmeter designed for use with ion selective electrodes. Since the potential of pH indicator electrode changes with the pH value of solution, when pH indicator electrode (such as pH glass electrode) and reference electrode (such as saturated calomel electrode) are immersed in solution to form a measuring cell, the generated electromotive force is related to the pH value of the solution.

[0003] When a portable acidity meter is in use, the connecting wire is generally exposed to the outside, and bumps may easily damage the connecting wire, which may cause safety hazards when in use. At the same time, the connecting wire is easily damaged. Therefore, a portable acidity meter with a storable function is proposed. Utility Model Content

[0008] Furthermore, the connecting wire is wound around the connecting column, and an electrode protection tube is installed at one end of the connecting wire, and a sleeve is installed at the top end of the electrode protection tube.

[0009] Furthermore, a placement frame is installed on the back of the acidity meter housing, and slide grooves are symmetrically arranged on the placement frame, and connecting rods are installed inside the two groups of slide grooves.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1 and Figure 4A portable acidity meter with a storage function comprises an acidity meter housing 1, a connecting frame 4, a rotating rod 5 and a connecting column 15. The connecting frame 4 is installed at the top of the acidity meter housing 1. The top of the connecting frame 4 is rotatably connected to the rotating rod 5, and the inside of the connecting frame 4 is rotatably connected to the connecting column 15. The bottom of the rotating rod 5 extends to the inside of the connecting frame 4, and the bottom of the rotating rod 5 is fixedly connected to the connecting column 15. The rotating rod 5 is rotated, and the rotating rod 5 drives the connecting column 15 to rotate, and the connecting line 6 is wound around the connecting column 15 for storage.

[0021] Reference Figure 2 and Figure 3 A connecting wire 6 is provided at the top of the acidity meter housing 1, and the connecting wire 6 is wound on the connecting column 15, and an electrode protection tube 8 is installed at one end of the connecting wire 6, and a sleeve 9 is installed at the top of the electrode protection tube 8. A placement frame 7 is installed at the back of the acidity meter housing 1, and slide grooves 10 are symmetrically arranged on the placement frame 7, and connecting rods 11 are installed inside the two groups of slide grooves 10;

[0022] The two groups of connecting rods 11 are both slidably connected with connecting blocks 13, and a clamping plate 14 is installed between the two groups of connecting blocks 13. An arc groove is provided on one side of the clamping plate 14. The arc groove on the clamping plate 14 clamps the outer side of the electrode protection tube 8, clamps the electrode protection tube 8 inside the placement frame 7, and the electrode protection tube 8 is stored inside the placement frame 7. The two groups of connecting rods 11 are both sleeved with springs 12, and a button 2 is installed on the acidity meter housing 1, and a display screen 3 is installed on the acidity meter housing 1.

[0023] Working principle: When in use, rotate the rotating rod 5, and the rotating rod 5 drives the connecting column 15 to rotate. When the connecting column 15 rotates, the connecting wire 6 is extended from the inside of the connecting frame 4 to the outside, and the electrode protection tube 8 is taken out of the placement frame 7 for use. When not in use, rotate the rotating rod 5 in the opposite direction to drive the connecting column 15 to rotate in the opposite direction, retract the extended connecting wire 6 into the inside of the connecting frame 4, and wrap it around the connecting column 15, and store the connecting wire 6 in the connecting frame 4, insert the electrode protection tube 8 between the card plate 14 and the placement frame 7, the card plate 14 slides on the placement frame 7, and the connecting block 13 slides on the connecting rod 11.
