Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a fixture for measuring resistivity of porous carbon materials. Background Art

[0002] Due to its rich pore structure and high specific surface area, porous carbon materials are widely used in daily life and industrial production, such as: absorption of harmful gases, adsorption of pollutants, storage and separation of gases, etc. In addition, due to the large specific surface area of ​​porous carbon materials, the research on its electrode material as a backup power supply and memory standby device supercapacitor is also more in-depth. When using porous carbon materials to prepare electrical device parts, it is usually necessary to detect resistance. Resistance is a physical quantity used to represent the resistance characteristics of various substances. It reflects the property of the material's resistance to current. It is not only related to the type of substance, but also affected by external factors such as temperature, pressure and magnetic field. When conducting resistivity tests on porous carbon materials, it is necessary to use a fixture to clamp the device, but the existing fixtures are difficult to adapt to samples of different shapes and sizes; in addition, the existing fixtures are difficult to flexibly adjust the position to quickly detect the samples to be tested in different test chambers, and the detection efficiency cannot be quickly improved.

[0003] In order to solve the deficiencies of the prior art, people have conducted long-term explorations and proposed various solutions. For example, a Chinese patent document discloses a resistivity test fixture [202321854990.6], which includes a bottom plate, a side plate vertically installed at one end of the bottom plate, and a top plate installed on both sides of the top of the other end of the side plate, and hydraulic columns are installed at the bottom ends of the two top plates, and the bottom ends of the two hydraulic columns are connected to a receiving plate. In the utility model, the staff first places the samples to be tested of each type of height in the grooves of each column, and then the hydraulic column works to move the receiving plate and multiple cover plates downward as a whole until the boss of a certain column contacts the highest sample to be tested, and the outer side of the gear circumference is engaged with a number of teeth, and then the staff manually rotates the rotating rod to make the gear drive the movable rod to move downward until the boss of the cover plate presses the sample to be tested inside the groove, and the boss and the groove are used as chucks, and then the wires at both ends are connected to the external resistance tester to form a loop for resistance measurement.

[0004] The above solution solves the problem in the prior art that the resistance detection fixture is difficult to adapt to samples of different specifications, but the solution still has many shortcomings. For example, it is difficult to flexibly adjust the position to quickly detect samples to be tested in different detection chambers, and the detection efficiency cannot be quickly improved.
