Description

Technical Field

[0001] This utility model relates to the field of conductivity testing technology, and in particular to a conductivity testing fixture that is easy to fix. Background Technology

[0002] Conductivity testing is an important technique for evaluating the electrical conductivity of materials, widely used in chemistry, environment, materials science, electronic engineering, and other fields. Conductivity, the ability of a material to conduct electric current, is a key indicator of a material's electrical properties. Conductivity testing provides in-depth understanding of a material's electrical characteristics, offering crucial data support for product quality control, scientific research, and application development. Various conductivity testing methods exist, including the two-electrode method, four-electrode method, electromagnetic induction method, and AC impedance method. Each method has its advantages and disadvantages, and is suitable for different types of samples and testing needs. For example, the two-electrode method is simple to operate and suitable for both solid and liquid samples; the four-electrode method improves measurement accuracy through four electrodes and is suitable for high-conductivity samples; the electromagnetic induction method is suitable for non-contact measurements under special environments such as high temperature and high pressure. Conductivity testing requires specialized testing instruments, such as conductivity meters, resistivity meters, multimeters, and electrochemical workstations. These instruments can accurately measure the conductivity of substances and are widely used in water quality testing, electrochemical research, and other fields. When selecting instruments, factors such as testing requirements, budget, and instrument performance must be considered. Certain procedures and precautions must be followed when conducting conductivity testing. First, appropriate testing methods and instruments must be selected, and the instruments must be ensured to be in good working order. Second, the sample to be tested must be prepared, ensuring that the sample temperature is stable and free from contamination. During the test, the electrodes must be kept in full contact with the sample to avoid air bubbles and impurities interfering with the measurement results. Furthermore, the instrument must be calibrated regularly to ensure the accuracy of the measurement results. Conductivity testing has wide applications in many fields. In water quality monitoring, measuring the conductivity of water can reveal the content and types of dissolved substances in the water; in chemical production processes, conductivity testing is used to monitor the concentration and purity of electrolyte solutions; in materials science, conductivity testing can evaluate the conductivity properties of materials, providing data support for the development of new materials; in electronic engineering, conductivity testing is used to evaluate the conductivity properties of electronic materials and optimize the design and manufacturing processes of electronic devices.

[0003] Conductivity testing fixtures are tools specifically designed to measure the electrical conductivity of materials, playing a crucial role in various fields such as electrochemistry, materials science, and electronic engineering. Conductivity testing fixtures are typically made of highly conductive materials, such as copper or gold-plated copper, to ensure low contact resistance and long-term stability. Their design considers versatility and adaptability, accommodating samples of different sizes and shapes, while providing stable contact and precise current control to ensure the accuracy and reliability of resistance measurements. During conductivity testing, the fixture typically contacts the sample via two pairs of clamps: one pair for applying current and the other for measuring voltage. The voltage drop generated when current flows through the sample is precisely measured, and the sample's conductivity is calculated from this voltage. This measurement technique eliminates the influence of test lead resistance and contact resistance on the measurement results, improving the accuracy of the test.

[0004] When conducting conductivity tests, a fixture is required to secure the probe. However, traditional fixtures are not convenient for position adjustment, lack quick clamping of the probe, and are inconvenient for fine-tuning after clamping. Therefore, there is an urgent need for a conductivity test fixture that is easy to fix to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a conductivity testing fixture that is easy to fix, which solves the problems of existing fixtures that are not easy to adjust in position, lack quick clamping of the probe when fixing the probe, and are inconvenient to fine-tune the fixture after clamping the probe.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A conductivity test fixture that is easy to fix includes a frame, on one side of the inner side of the frame, a conductivity tester, a top plate on one side of the top of the frame, a sliding rod fixedly connected between the bottom of the top plate and the bottom of the inner side of the frame, a sliding sleeve fitted on the sliding rod, side plates fixedly connected on both sides of the sliding sleeve, a telescopic rod fixedly connected between the top of the two side plates and the bottom of the top plate, and an elastic connection between the top of the side plates and the bottom of the top plate, a threaded rod on one side of the frame, the top of the threaded rod rotatably connected to a bottom plate via a pivot, and the bottom end of the threaded rod penetrating the bottom of the frame through a threaded groove, a deformable connecting rod fixedly connected to one side of the sliding sleeve, a hook fixedly connected to one end of the deformable connecting rod, and a hanging groove for use with the hook on the bottom plate;

[0008] A fixed plate is fixedly connected to one side of the sliding sleeve, and a clamping frame is slidably connected to one side of the fixed plate. Both sides of the inner side of the clamping frame are provided with elastic clamping plates. One side of one of the two elastic clamping plates is fixedly connected to the inner wall of the clamping frame, and one side of the other elastic clamping plate is elastically connected to the inner wall of the clamping frame.

[0009] Preferably, a support plate is fixedly connected to one side of the bottom inner side of the frame, and the support plate is located on the bottom side of the clamping frame.

[0010] Preferably, each of the two telescopic rods is fitted with a tension spring, and the top of each of the two side plates is elastically connected to the bottom of the top plate through the tension spring.

[0011] Preferably, a slider is fixedly connected to one side of the clamping frame, and the slider is slidably connected to the fixed plate through a groove.

[0012] Preferably, one of the two elastic clamps is elastically connected to the inner wall of the clamping frame via a compression spring.

[0013] Preferably, one side of one of the two elastic clamping plates is fixedly connected to a support rod, and one end of the support rod penetrates through the side wall of the clamping frame, and the connection between the one end of the support rod and the clamping frame is a sliding connection.

[0014] This utility model has the following beneficial effects:

[0015] The solution to be tested is placed on top of the support plate, and the probe is clamped by the cooperation of two elastic clamps. The sliding sleeve on the sliding rod is slid up and down, thereby adjusting the clamping frame as a whole and maintaining the stability of the clamping frame on the fixed plate to prevent the fixed plate from falling. Finally, the hook on the deformable connecting rod can be attached to the hanging groove on the base plate to maintain the stability of the clamping frame. The position of the base plate is adjusted by rotating the threaded rod. Compared with the existing clamps, which are not convenient for position adjustment, and which lack quick clamping of the probe and are inconvenient for fine-tuning the clamp after clamping the probe, the method proposed in this utility model adjusts the clamping frame by moving it up and down, and provides basic limiting and fixing of the clamping frame after adjustment without completely fixing it, which facilitates subsequent fine-tuning and has high practicality.

The telescopic rod 6 improves the stability of the sliding sleeve 4 during movement. The frame 1 is elastically connected to the bottom plate 9 via a pivot at one side. The bottom of the threaded rod 21 passes through the bottom of the frame 1 via a threaded groove. The rotation of the threaded rod 21 allows the bottom plate 9 to move up and down.
