Technical Field
[0001] The utility model relates to the field of moisture measuring devices, in particular to a moisture measuring device for preparing pharmaceutical intermediates. Background Art
[0002] A moisture meter is an instrument that can detect the moisture content in various organic and inorganic solids, liquids and other samples. It can be widely used in all industries that require rapid moisture measurement, such as medicine, grain, feed and other industries. The most common test method for moisture meters on the market is the loss on drying method, which evaporates the water in the sample by heating it, and then measures the mass change of the sample before and after heating to calculate the moisture content.
[0003] In the prior art, moisture meters on the market usually have a heating component disposed on a cover plate, so a plurality of heat dissipation ports are usually provided on the top surface of the cover plate for heat dissipation. However, the heat dissipation ports usually do not have a good dustproof mechanism, which may cause dust and other floating impurities in the external environment to enter the cover plate through the heat dissipation ports and adhere to the instrument inside the cover plate. If the dust is not cleaned in time, the dust accumulates more and more, which may affect the subsequent measurement accuracy of the moisture content of pharmaceutical intermediates. Therefore, a moisture measuring device for the preparation of pharmaceutical intermediates is needed. Utility Model Content

[0024] Reference Figure 1-5 The embodiment of the utility model is a moisture measuring device for preparing pharmaceutical intermediates, which includes a moisture meter 1. The moisture meter 1 is provided with a cover plate 2, and a plurality of heat dissipation ports 3 are opened on the cover plate 2. A connecting ring 4 is fixedly connected to the upper surface of the cover plate 2, and a positioning block 5 is fixedly connected to the upper surface of the connecting ring 4. A movable block 6 is movably connected to the connecting ring 4, and a positioning groove 7 is opened on the movable block 6. A filter screen 8 is fixedly connected to the inner surface of the movable block 6, and the outer surface of the positioning block 5 is movably connected to the positioning groove 7.
[0025] The inner surface of the connecting ring 4 is fixedly connected to two guide rods 9, and the two guide rods 9 are slidably connected to a slider 10. The corresponding two sliders 10 are fixedly connected to the same movable rod 11, and the two movable rods 11 are fixedly connected to two fixed blocks 12. The movable block 6 is fixedly connected to four connecting rods 13. The outer surfaces of the four connecting rods 13 are rotatably connected to rotating rods 14. The four rotating rods 14 are provided with fixed grooves 15. The outer surface of the fixed block 12 is movably connected to the fixed groove 15. The guide rod 9 passes through the slider 10. The outer surface of the slider 10 is slidably connected to the connecting ring 4. The end of the rod 13 away from the movable block 6 is fixedly connected to the anti-slip block 16, the side surface of the anti-slip block 16 is in contact with the rotating rod 14, the outer surface of the guide rod 9 is slidably sleeved with a spring 17, one end of the spring 17 is fixedly connected to the side surface of the slider 10, the end of the spring 17 away from the slider 10 is fixedly connected to the side inner wall of the connecting ring 4, a stopper 18 is fixedly connected to the movable block 6, the side surface of the rotating rod 14 is in contact with the stopper 18, the side surface of the movable rod 11 is in contact with the rotating rod 14, the outer surface of the connecting ring 4 is in contact with the movable rod 11, and there are four stoppers 18 distributed in a rectangular array.
[0026] Working principle: Under the action of the filter 8, the heat dissipation port 3 can be protected, thereby preventing dust and other impurities in the outside air from entering the cover plate 2 through the heat dissipation port 3, thereby ensuring the cleanliness of the instrument in the cover plate 2. By pulling the movable rod 11, the movable rod 11 can drive the fixed block 12 and the slider 10 to move, and the slider 10 will gradually squeeze the spring 17 during the movement on the guide rod 9, so that the spring 17 is in a taut state. When the movable fixed block 12 is separated from the fixed groove 15, the rotation is released. The two rotating rods 14 are fixed, and then the two rotating rods 14 are rotated respectively, so that the rotating rod 14 and the fixed groove 15 rotate with the connecting rod 13 as the central axis. When the rotating fixed groove 15 no longer corresponds to the fixed block 12, the pulled movable rod 11 is released, so that the spring 17 is no longer restricted by the tension and rebounds, so that the rebound spring 17 can drive the slider 10, the movable rod 11 and the fixed block 12 to reset, and then the other side performs the above operation again. When all the fixed blocks 12 are separated from the fixed groove 15, the movable block 6 and the movable block 6 are released. The structure on the block 6 is fixed, and then the movable block 6 is pulled upward to remove the movable block 6, the filter 8 and the structure on the movable block 6 from the connecting ring 4, thereby facilitating the cleaning of the filter 8. When the filter 8 is cleaned, the positioning slot 7 is inserted into the positioning block 5, and then the movable rod 11 is pulled to move the movable rod 11 to drive the slider 10 and the fixed block 12 to move while keeping the spring 17 in a taut state. When the moving fixed block 12 does not affect the rotation of the rotating rod 14, the two rotating rods 14 are rotated in opposite directions respectively so that the rotating rod 14 and the fixed block 12 are in a taut state. The fixed slot 15 rotates in the opposite direction. When the rotating rotating rod 14 contacts the stop block 18, the fixed slot 15 can correspond to the fixed block 12. Then the movable rod 11 is released to make the spring 17 rebound, so that the rebound spring 17 drives the slider 10, the movable rod 11 and the fixed block 12 to move back. When the movable fixed block 12 is inserted into the fixed slot 15, the above operation is performed on the other side, thereby completing the fixation of the movable block 6 and the structure on the movable block 6, so that the filter 8 can be stably located on one side of the heat dissipation port 3 for protection.
[0027] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
