Description

Technical Field

[0001] This utility model relates to the field of ion detection technology, specifically a benchtop ion meter. Background Technology

[0002] Benchtop ion meters are important analytical instruments used to measure the concentration of ions in solutions. They are widely used in many fields such as chemical analysis, environmental monitoring, and biomedicine. They convert ion concentration signals into electrical signals through contact with the solution to be tested via electrodes and other components, and then process and display the signals to provide accurate ion concentration data for related research and production.

[0003] However, existing benchtop ion meters have some problems during use. On the one hand, the electrodes and other components are connected by a lot of cables, which are easy to get tangled together during use. This not only affects the convenience of operation, but may also interfere with the stability of the instrument connection due to pulling. On the other hand, the instrument stand used to fix the electrodes and other detection components is prone to tipping over if it is accidentally touched or interfered with by external force, due to the lack of a stable fixing structure. This can damage the instrument or adversely affect the detection process. Utility Model Content

[0017] Please refer to Figures 1 to 6 This utility model provides a technical solution: a benchtop ion meter, including a mounting base 1, an ion detector 2 mounted on the upper side of the mounting base 1, a mounting plate 3 fixedly connected to the upper side of the mounting base 1, a plurality of rotating shafts 4 rotatably engaged on one side of the mounting plate 3, a winding roller 5 fixedly connected to the end of the rotating shaft 4 away from the ion detector 2, a spring 6 fixedly connected to the side of the mounting plate 3 near the winding roller 5, a ratchet 7 fixedly connected to one end of the rotating shaft 4 through the mounting plate 3, a pawl 8 rotatably engaged with the ratchet 7 on one side of the mounting plate 3, a compression spring 9 mounted on one side of the mounting plate 3, an adjusting arm 10 provided on the upper side of the mounting base 1, a T-shaped groove 12 opened on one side of the mounting base 1, a T-shaped slider 13 slidably engaged on the inner wall of the T-shaped groove 12, a mounting groove 14 opened on one side of the inner wall of the T-shaped groove 12, and a limit mechanism 15 provided on the inner wall of the mounting groove 14. The ion detector 2 on the mounting base 1 is used for ion detection. The rotating shaft 4 on the mounting plate 3 supports the winding roller 5. The spring 6 provides winding force. When the wire is pulled, the winding roller 5 drives the rotating shaft 4 to rotate, the spring 6 stores force, the ratchet 7 and the pawl 8 engage to prevent reverse rotation, and the compression spring 9 ensures that the pawl 8 is in contact with the ratchet 7. This structure can release the wire and fix the length as needed, avoid cable tangling, ensure stable connection, and improve the convenience of operation.

[0018] In this embodiment, the movable end of the spring 6 is fixedly connected to one side of the rotating shaft 4, and the lower end of the compression spring 9 is fixedly connected to the upper side of the pawl 8. A snap-fit ​​bracket 11 is mounted on the movable end of the adjusting arm 10, and the adjusting arm 10 is fixedly connected to the upper side of the T-shaped slider 13. The winding roller 5 is used to wind and fix the connecting wires of the ion detector 2, and the outer slot of the snap-fit ​​bracket 11 is used to snap the probe end of the connecting wires. The movable end of the spring 6 is connected to the rotating shaft 4, causing the winding roller 5 to automatically wind up. The compression spring 9 is connected to the pawl 8, ensuring reliable engagement with the ratchet 7. The adjusting arm 10 is detachably mounted on one side of the mounting base 1 via the T-shaped slider 13 in the T-shaped groove 12. The snap-fit ​​bracket 11 at its movable end snaps the probe end, the winding roller 5 collects the wires, and the snap-fit ​​bracket 11 fixes the probe. This combination achieves orderly management of the wires and flexible positioning of the probe, reducing pulling damage and optimizing the operating space.

[0019] In this embodiment, the limiting mechanism 15 includes a drive rod 151 rotatably engaged with the lower side of the inner wall of the mounting groove 14. A cam 152 is fixedly connected to the drive rod 151. A torsion spring 153 is fixedly connected to the inner wall of the mounting groove 14. A knob 154 is fixedly connected to the upper end of the drive rod 151 extending to the upper side of the mounting base 1. The limiting mechanism 15 also includes an insert rod 155 slidably engaged with one side of the inner wall of the mounting groove 14. A roller 156 is rotatably engaged with one end of the insert rod 155 near the cam 152. A spring 157 is fixedly connected to one side of the inner wall of the mounting groove 14. A slot 158 ​​is provided on the side of the T-shaped slider 13 near the insert rod 155. The movable end of the torsion spring 153 is fixedly connected to one side of the drive rod 151, the roller 156 is in contact with one side of the cam 152, one end of the spring 157 abuts against the boss of the insert rod 155, the insertion end of the insert rod 155 is inserted into the slot 158, and the elastic potential energy of the torsion spring 153 is greater than that of the spring 157. In the limiting mechanism 15, the drive rod 151 drives the cam 152 to rotate, the torsion spring 153 resets the drive rod 151, and the knob 154 facilitates operation. The cam 152 pushes the insertion rod 155 with the roller 156, and the spring 157 helps it to reset. The insertion rod 155 cooperates with the slot 158 ​​to limit the T-shaped slider 13. The elasticity of the torsion spring 153 ensures that the insertion rod 155 is stably inserted. Rotating the knob 154 can release the limit, realizing the fixed and flexible adjustment of the position of the adjusting arm 10, enhancing the structural stability. The position of the adjusting arm 10 can be separated by separating the T-shaped slider 13, thereby facilitating the movement of the position of the adjusting arm 10 and improving the convenience of detection.

[0020] When using the device, pull the connecting wire of the ion detector 2, the winding roller 5 rotates to release the wire, the spring 6 stores power, the ratchet 7 and the pawl 8 cooperate to maintain the wire length, the wire probe end is inserted into the clip 11, and the adjusting arm 10 slides to the appropriate position through the T-shaped slider 13 in the T-shaped groove 12. The insertion rod 155 of the limiting mechanism 15 is inserted into the slot 158 ​​for fixation. After the detection is completed, move the pawl 8, the spring 6 drives the winding roller 5 to retract the wire. This process realizes the orderly winding and unwinding of the wire, the flexible positioning and stable fixation of the probe, avoids tangling and instrument tipping, and improves detection efficiency and safety. The multiple rotating shafts 4 on the mounting plate 3 correspond to different types of ion-selective electrode wires. Each winding roller 5 winds a wire separately to avoid confusion and tangling of different electrode cables. The snap-fit ​​bracket 11 at the movable end of the adjusting arm 10 is equipped with multiple slots for different probes, which can simultaneously fix multiple detection probes such as pH, chloride ion, and sodium ion. Multiple probes can be inserted into different areas of the solution to be tested at the same time or in batches for multi-ion detection. The ion detector 2 has a built-in multi-channel signal processing module, which can simultaneously receive and analyze the electrical signals transmitted by different probes, and finally output the concentration data of multiple ions to meet the multi-parameter detection requirements of complex samples and improve detection efficiency and practicality.
