Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and more specifically to a high-precision electronic measuring instrument. Background Technology

[0002] Measuring the surface tension of water is crucial for a deeper understanding of the microscopic interactions of matter. Surface tension originates from the cohesive forces of hydrogen bonds between water molecules. Quantitative analysis of surface tension reveals the energy state and molecular arrangement of liquid surfaces, providing core data for studying the physical nature of fluid dynamics, phase transitions, and other phenomena. In industry, precise measurement of surface tension can optimize processes such as chemical separation, paint spraying, and pesticide atomization, improving production efficiency by controlling liquid spreadability. In scientific research and innovation, this parameter drives the development of cutting-edge technologies such as superhydrophobic materials and microfluidic chips, and provides theoretical support for simulating biomembrane behavior. In the biomedical field, surface tension data helps design efficient respiratory therapy devices, optimize drug microvesicle preparation processes, and even influence cell culture medium ratios and artificial organ interface design, becoming a key link between basic science and applied technology.

[0029] The working principle of this utility model:

[0030] First: Multiple measuring containers 4 containing different aqueous solutions can be placed on belt 302 at once. Start motor 201. The first rotating shaft 202, fixedly connected to the output end of motor 201, rotates. The rotation of the first rotating shaft 202 drives the eccentric block 203, which is fixedly connected to it, to rotate. The rotation of the eccentric block 203 lifts and lowers pulley 205. The lifting and lowering of pulley 205 drives the sliding rod 204, which is rotatably connected to it, to lift and lower. The lifting and lowering of sliding rod 204 causes the connecting plate 6, which is fixedly connected to it, to move up and down. The up and down movement of connecting plate 6 causes the telescopic measuring head 5, which is fixedly connected to it, to move up and down. 5. When moving downwards, the aqueous solution in the tank 401 is measured. The first rotating shaft 202 rotates, causing the turntable 206 fixedly connected to it to rotate. The rotation of the turntable 206 causes the connecting rod 207 fixedly connected to it to rotate. The rotation of the connecting rod 207 causes the intermittent plate 208 sliding with it to rotate intermittently. The intermittent rotation of the intermittent plate 208 causes the second rotating shaft 209 fixedly connected to it to rotate intermittently. The setting of the intermittent mechanism 2 enables the measuring instrument to measure the tension of various aqueous solutions without the need for frequent calibration when switching aqueous solution types. This makes the operation more convenient, the response speed is fast, and it can realize rapid and continuous multi-solution tension detection.

[0031] Secondly: the intermittent rotation of the second rotating shaft 209 drives the intermittent rotation of the first synchronous pulley 301, the intermittent rotation of the first synchronous pulley 301 drives the intermittent transmission of the belt 302, and the intermittent transmission of the belt 302 drives the transmission of the measuring bucket 4.

[0032] Finally: When passing the first rack 107, the gear 403 meshing with the rack 107 rotates half a turn. The gear 403 rotates half a turn, causing the third rotating shaft 402 fixedly connected to it to rotate half a turn. The third rotating shaft 402 rotates half a turn, causing the cover 404 fixedly connected to it to rotate half a turn. The cover 404 rotates half a turn, causing the aqueous solution in the barrel 401 to leak out and be transmitted to the telescopic measuring head 5. The telescopic measuring head 5 measures the tension of the aqueous solution. Then, after passing the second rack 107, the cover 404 rotates half a turn again to seal the aqueous solution, preventing contamination, maintaining solution concentration, avoiding evaporation, and ensuring measurement accuracy.
