Technical Field
[0001] This utility model relates to the field of polarimeter base technology, and in particular to a stable base for an automatic polarimeter. Background Technology
[0002] An automatic polarimeter is a precision optical instrument used to measure the optical rotation of substances. It is widely used in the fields of medicine, food, and chemical industry to determine key parameters such as specific rotation, concentration, and purity of samples. Its measurement accuracy directly depends on the stability of the instrument, especially the levelness and fixation reliability of the base. Traditional bases lack effective leveling methods. Once the platform is tilted or uneven, the automatic polarimeter cannot be in an ideal horizontal position, which affects the alignment accuracy of the optical components and causes measurement deviations. Existing fixing structures are often designed in a single way and lack flexibility and versatility.
[0003] For example, announcement number CN220508762U describes a fully automatic polarimeter stabilizing base, comprising: a main body including a mounting base, on which a connecting block is fixedly connected, and the polarimeter main body is disposed on the upper surface of the mounting base; and an adjusting mechanism including a fixing plate fixedly connected to the upper surface of the mounting base, a locking rod fixedly connected to the lower surface of the polarimeter main body, a positioning plate fixedly connected to the surface of the fixing plate, and an adjusting bolt threadedly connected to the surface of the positioning plate. This invention, through the cooperation of the fixing plate, locking rod, positioning plate, and adjusting bolt, ensures that the polarimeter main body remains horizontal on the mounting base, avoiding the phenomenon of polarimeter tilting caused by the tilt of the worktable, and improving the accuracy of polarimeter measurements.
[0004] The aforementioned fully automatic polarimeter stabilizing base is inconvenient to level during use, affecting the alignment accuracy of optical components and causing measurement deviations. Furthermore, it is not convenient to fix automatic polarimeters of different specifications, lacking flexibility and versatility. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0023] like Figures 1-6 As shown, this embodiment provides a stable base for an automatic polarimeter, including a mounting plate 1. Levels 2 are provided on both sides of the mounting plate 1. A leveling assembly 3 arranged in an array is provided on the mounting plate 1 to eliminate the influence of unevenness on the measurement results, ensure that the automatic polarimeter is in a horizontal position, and provide a foundation for accurate measurement. A fixing assembly 4 is slidably engaged on the mounting plate 1 to fix polarimeters of different specifications, effectively preventing displacement of the polarimeter during the detection process, ensuring the accuracy of the measurement results, and improving the applicability of this technical solution.
[0024] The leveling assembly 3 includes a mounting sleeve 301, which is fixedly mounted on the mounting plate 1. A threaded rod 302 is rotatably mounted on the mounting sleeve 301. A handwheel 303 is provided at the upper end of the threaded rod 302. A leveling rod 304 is slidably engaged inside the mounting sleeve 301. The leveling rod 304 has a hollow internal structure and is threadedly connected to the threaded rod 302. A limiting groove 305 is provided inside the mounting sleeve 301, and the two sides of the leveling rod 304 are slidably engaged in the limiting groove 305. Inside 5, rotating the handwheel 303 causes the threaded rod 302 to rotate accordingly. Driven by the threaded rod 302, the leveling rod 304 can slide stably up and down along the direction of the limiting groove 305. During the adjustment process, the level 2 is continuously observed. Based on the movement of the bubble in the level 2, the leveling rod 304 at different positions is adjusted accordingly. The mounting plate 1 is leveled by the leveling assembly 3, providing a stable horizontal base for the automatic polarimeter and ensuring the accuracy of the polarimeter's measurement results.
[0025] The fixing component 4 includes a slide rod 401, which is fixedly installed inside the slide groove 5. A slider 402 is inserted into the slide rod 401 and slidably engaged inside the slide groove 5. A first spring 403 is sleeved on the slide rod 401, with both ends of the first spring 403 fixedly connected to the slider 402 and the slide groove 5, respectively. The slider 402 has an installation groove 404, which slidably engages with a pressing plate 405. A locking block 406 is connected to the pressing plate 405 and matches the positioning hole 6. A second spring 407 is connected to the pressing plate 405, with the other end of the second spring 407 fixedly connected to the installation groove 404. A clamping plate 408 is connected between the sliders 402. Pressing the pressing plate 405 overcomes the elastic force of the second spring 407 and slides downward, causing the locking block 406 to move and disengage from the positioning hole. 6. According to the size of the automatic polarimeter, adjust the slider 402 to a suitable position. When the slider 402 moves to the ideal position, release the pressing plate 405. Under the action of the second spring 407, the pressing plate 405 drives the locking block 406 to move upward and re-engage with the positioning hole 6, thereby fixing the position of the slider 402. The upper end of the clamping plate 408 is provided with an electric telescopic rod 409. The output end of the electric telescopic rod 409 is connected to the lower pressure plate 410. Start the electric telescopic rod 409 to drive the lower pressure plate 410 to gradually approach the automatic polarimeter. The lower pressure plate 410 gradually contacts the top of the automatic polarimeter and applies pressure. At the same time, the clamping plate 408 clamps the automatic polarimeter from both sides to ensure that the automatic polarimeter is firmly fixed on the base and will not shift or shake during subsequent testing, thus affecting the test results.
[0026] In use, the mounting plate 1 is placed in a suitable position. The level indicator 2 shows the mounting plate 1 is tilted. Turning the handwheel 303 causes the threaded rod 302 to rotate, and the leveling rod 304, driven by the threaded rod 302, can stably slide up and down along the direction of the limiting groove 305. During adjustment, the level indicator 2 is continuously observed, and adjustments are made to the leveling rod 304 at different positions based on the movement of the bubble in the level indicator 2. The mounting plate 1 is leveled by the leveling assembly 3, providing a stable horizontal base for the automatic polarimeter. Pressing the pressing plate 405 overcomes the elastic force of the second spring 407 and slides downwards, causing the locking block 406 to move and disengage from the positioning hole 6. The size of the automatic polarimeter is adjusted accordingly. Adjust slider 402 to a suitable position. Once slider 402 has moved to the ideal position, release press plate 405. Under the action of second spring 407, press plate 405 drives snap-fit block 406 to move upward and re-engage with positioning hole 6, thereby fixing the position of slider 402. Place automatic polarimeter on mounting plate 1 and position it between clamping plates 408. Activate electric telescopic rod 409 to drive lower pressure plate 410 to gradually approach automatic polarimeter. Lower pressure plate 410 gradually contacts the top of automatic polarimeter and applies pressure. At the same time, clamping plates 408 clamp the automatic polarimeter from both sides to ensure that the automatic polarimeter is firmly fixed on this base and will not shift or shake during subsequent testing, thus affecting the test results.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
