Description

Technical Field

[0001] This utility model relates to the field of trace moisture analyzers, specifically to an automatic fixing device for a trace moisture analyzer. Background Technology

[0002] A trace moisture analyzer is an instrument used to measure the moisture content of a sample. It is commonly used in laboratories and industrial production to determine the moisture content of various substances, such as food, pharmaceuticals, and chemical products. The automatic fixing device of a trace moisture analyzer is a device used to stabilize and fix the sample to be tested, ensuring that the sample's position does not change during the measurement process, thus ensuring the accuracy and reliability of the measurement. This device typically consists of a support or clamp that can be adjusted and fixed according to the shape and size of the sample. Some automatic fixing devices may also include a precise position calibration system to ensure that the sample is placed in the correct position in each measurement.

[0003] A search revealed that Chinese patent CN208350709U discloses a fixing device for a trace moisture analyzer. The patent describes a technical solution that uses a limiting ring and a limiting base to stabilize the glass bottle of the anode chamber from two directions: fixing the glass bottle and limiting its swaying. This improves the stability of the trace moisture analyzer and allows for accurate moisture content measurements.

[0004] In this solution, the device is fixed and supported by a simple limiting ring. However, when testing different bottle bodies, the limiting ring cannot be adapted to bottle bodies of different diameters, resulting in unstable support. This requires manual fixing by the staff, causing fluctuations in the testing structure, which affects work efficiency and data accuracy. To solve this technical problem, this utility model proposes an automatic fixing device for a trace moisture analyzer. Summary of the Invention

[0014] (III) Beneficial Effects

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: An automatic fixing device for a trace moisture analyzer includes an analyzer body 1. A connecting frame 9 is provided on the top of the analyzer body 1. Fixing blocks 10 are fixedly connected to both sides of the top of the connecting frame 9. Nuts 13 are fixedly connected to the outer walls of both fixing blocks 10. Threaded rods 12 are threadedly connected inside the nuts 13. The threaded rods 12 pass through the nuts 13 and extend to the outer walls of the fixing blocks 10. A clamping plate 14 is fixedly connected to the other end of the threaded rod 12. The clamping plate 14 is slidably connected to the connecting frame 9. Slider blocks 15 are fixedly connected to both sides of the clamping plate 14. At the same time, a pair of positioning rods 11 are fixedly connected between the two fixing blocks 10. The sliders 15 are slidably connected to the outer walls of the positioning rods 11. Anti-slip pads 8 are provided on the inner walls of the clamping plates 14. A cup body 16 is provided between the two clamping plates 14. A pair of probes 17 are provided inside the cup body 16. A placement plate 18 is fixedly connected to the top of the analyzer body 1. The cup body 16 is placed on top of the placement plate 18.

[0026] The measuring instrument body 1 is placed between the two clamping plates 14 and simultaneously placed on the placement plate 18 on top of the measuring instrument body 1. Then, by rotating the threaded rod 12 within the fixing block 10 on the connecting frame 9, and with the nut 13 controlling its movement, the threaded rod 12 begins to move inward. This movement causes the clamping plates 14 to gradually approach and fix onto the cup body 16. To prevent the cup body 16 from slipping, the anti-slip pad 8 acts as a retaining element. During the movement of the clamping plates 14, the sliders 15 on both sides are limited by the positioning rod 11, ensuring that the clamping plates 14 move in the same direction. This automatic fixing device design allows cup bodies 16 of different diameters to be placed quickly and stably, improving the operating efficiency of the measuring instrument and ensuring the accuracy of the measurement results. Through this automatic fixing device, users can perform measurements more conveniently and quickly, reducing possible human error and improving the reliability and accuracy of the entire measurement process.

[0027] Example 2: The difference between this example and Example 1 is that the top of the measuring instrument body 1 is fixedly connected to a bracket 2. The outer wall of the bracket 2 has two pairs of sliding grooves 3. The bracket 2 has multiple inner holes 4. A pair of connecting plates 7 are provided on the outside of the bracket 2. One end of each of the two probe heads 17 is fixedly connected to a connecting hole 6. The connecting hole 6 corresponds to the sliding groove 3 and is slidably connected in the sliding groove 3. A pin 5 is provided between the bracket 2 and the connecting hole 6. The pin 5 corresponds to the inner hole 4 and passes through the connecting hole 6 and extends to the outside of the bracket 2. The connecting plate 7 is fixedly installed on the connecting frame 9 by screws and is slidably connected to the outside of the bracket 2.

[0028] The height is adjusted by pushing the connecting plate 7 up or down. The connecting bracket 9 is fixed to the connecting plate 7 with screws, so adjusting the height of the connecting plate 7 adjusts the height of the connecting bracket 9, which in turn adjusts the clamping plate 14 to accommodate cups 16 of different heights. When the connecting plate 7 is pushed up, the connecting hole 6 is confined within the slide groove 3, ensuring that the moving direction of the connecting plate 7 is consistent. When adjusted to the appropriate position, the inner hole 4 on the connecting hole 6 aligns with the inner hole 4 on the height-adjusted bracket 2, and then the pin 5 can be directly inserted into the inner hole 4 to achieve a fixed installation. Through these designs, work efficiency is significantly improved. The user can then insert the probe 17 into the instrument body 1 to analyze the moisture content through the instrument body 1. The cooperation of these adjustment and fixing devices makes operation more convenient and reliable, providing a more flexible and efficient way to use the trace moisture analyzer.

[0029] During operation, when staff need to test the moisture content of a sample, they first pour the sample into the cup 16, then place the measuring instrument body 1 between the two side clamps 14 and on the placement plate 18 on top of the measuring instrument body 1. Then, they rotate the threaded rod 12 inside the fixing block 10 on the connecting frame 9. As the threaded rod 12 rotates, it is limited by the nut 13, causing it to gradually move inward. This inward movement of the threaded rod 12 drives the clamps 14 inward, gradually approaching the cup 16. Simultaneously, the anti-slip pad 8 prevents the cup 16 from slipping during fixing. As the clamps 14 move, they are limited by the side sliders 15 on the positioning rod 11, ensuring the clamps 14 maintain a consistent direction during movement. Through their cooperation, different types of samples are quickly fixed. The effect of different diameter cups 16 improves work efficiency. Since the height of different cups 16 will vary, the connecting plate 7 is pushed up or down. The connecting bracket 9 is then installed on the connecting plate 7 with screws. Therefore, adjusting the height of the connecting plate 7 can directly adjust the height of the connecting bracket 9, thereby adjusting the clamping plate 14 to adapt and fix cups 16 of different heights. When the connecting plate 7 is pushed up, it is limited in the slide groove 3 by the connecting hole 6, so that the moving direction of the connecting plate 7 is consistent. When it is adjusted to the appropriate position, at the same time, the inner hole 4 on the connecting hole 6 is aligned with the inner hole 4 on the bracket 2 after the height is adjusted. Then, the pin 5 is directly inserted into the inner hole 4 to achieve fixed installation. Through their cooperation, the work efficiency is greatly improved. The probe 17 is then inserted into the measuring instrument body 1 for analysis.
