Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical experimental sampling tools, and in particular to a pharmaceutical experimental sampling tool. Background Technology
[0002] Pharmaceutical laboratory sampling tools are devices used to extract, measure, or transfer liquid samples. Their main function is to ensure the accuracy of the volume of the drug solution in the experiment, avoid contamination or errors caused by manual operation that could lead to too much or too little sampling, and thus ensure the reliability of the experimental data.
[0003] However, existing pharmaceutical laboratory sampling tools on the market have relatively fixed structures and cannot be adjusted to accommodate the width and height of containers. This makes it inconvenient for staff to use the sampling tools to extract the liquid medicine from containers of different sizes, reducing the applicability of the sampling tools. Furthermore, when using the sampling tools, the medicine needs to be put into the sampling tool first and then transferred to other containers. During the transfer process, the medicine may come into contact with air or environmental pollutants, affecting the purity of the sample.
[0004] Therefore, those skilled in the art have provided a pharmaceutical experimental sampling tool to address the problems mentioned in the background section. Utility Model Content

[0009] Furthermore, all of the first connecting blocks slide inside the first groove, and a support plate is fixedly connected to the middle of the front outer wall of the first connecting block;
[0010] Through the above technical solution, the support plate can clamp containers of different widths by sliding the connection between the first connecting block and the first groove.
[0011] Furthermore, the second connecting block slides inside the second groove;
[0012] With the above technical solution, the sampling cylinder moves up and down by sliding the second connecting block inside the second groove, which facilitates the measurement of the reagent in containers of different heights.
[0013] Furthermore, each of the clamping blocks is slidably connected to the fixing plate, and the inner wall of each clamping block on the side near the center of the support frame is tightly fitted with the sampling cylinder.
[0014] The above technical solution ensures that the sampling tube is vertical by tightly fitting the clamping block with the sampling tube, making it easier for the user to penetrate the liquid inside the sampling tube.
[0015] Furthermore, a scale line is provided in the middle of the outer wall of the front end of the sampling tube;
[0016] The above technical solution uses a scale line set in the middle of the outer wall of the front end of the sampling tube to facilitate accurate liquid extraction by the user.
[0017] Furthermore, a storage box is threadedly connected to the middle of one side of the outer wall of the mounting block, and a storage cover is threadedly connected to the middle of the upper surface of the storage box;
[0018] The above technical solution, through the combined use of the storage box and the storage cap, reduces the risk of liquid contamination within the sampling tube.
[0019] This utility model has the following beneficial effects:
[0020] 1. The present invention proposes a pharmaceutical experimental sampling tool, which, through a sampling cylinder with an adjustable height according to the container and a support plate with an adjustable width, enables the sampling tool to extract containers of different widths and heights and to smoothly enter the interior of the solution, thereby improving the applicability of the sampling tool.
[0021] 2. The pharmaceutical experimental sampling tool proposed in this utility model allows the medicine in the sampling tube to be temporarily sealed and stored in the storage box through the threaded connection between the storage box and the storage lid, reducing the possible contact of the medicine with air or environmental pollutants during the transfer process, thereby improving the purity of the sample.

A first connecting block 5 is threaded to both sides of the outer wall of the bidirectional threaded rod 2. A second groove 24 is formed in the middle of the outer wall of the front end of the support frame 7. A first threaded rod 8 is rotatably connected to the middle of the bottom surface inside the second groove 24. The upper end of the first threaded rod 8 passes through the second groove 24 to the outside of the support frame 7. A second rotating handle 9 is fixedly connected to the sample tube 17. A second connecting block 10 is threadedly connected to the middle of the outer wall of the first threaded rod 8. Limiting blocks 13 are fixedly connected to both ends of the outer front end of the fixing plate 12. A second threaded rod 14 is threadedly connected to the middle of each limiting block 13. A clamping block 16 is rotatably connected to the side of the second threaded rod 14 near the center of the support frame 7.

An installation block 20 is connected through the upper end of the outer wall of one side of the sampling tube 17.
[0030] Reference Figure 3-4The first connecting block 5 slides inside the first groove 4. A support plate 6 is fixedly connected to the middle of the outer wall of the front end of the first connecting block 5. A support frame 7 is fixedly connected to the middle of the upper surface of the base 1. Through the sliding connection between the first connecting block 5 and the first groove 4, the support plate 6 can clamp containers of different widths. The second connecting block 10 slides inside the second groove 24. An extension plate 11 is fixedly connected to the middle of the outer wall of the front end of the second connecting block 10. A fixing plate 12 is fixedly connected to the middle of the outer wall of the front end of the extension plate 11. Through the sliding of the second connecting block 10 inside the second groove 24, the sampling cylinder moves up and down, which is convenient for measuring the medicine in containers of different heights. The clamping blocks 16 are respectively fixed to the fixed The plate 12 is slidably connected, and the inner wall of the clamping block 16 on the side near the center of the support frame 7 is tightly fitted with the sampling cylinder 17. The tight fit between the clamping block 16 and the sampling cylinder 17 makes the sampling cylinder 17 vertical, which facilitates the user to penetrate the liquid in the sampling cylinder 17. A scale line 18 is provided in the middle of the outer wall of the front end of the sampling cylinder 17.

[0031] Working principle: First, rotating the No. 1 handle on one side of the base 1 drives the bidirectional threaded rod 2, which in turn adjusts the spacing of the two support plates 6 to accommodate containers of different widths. Next, rotating the No. 2 handle 9 at the top of the support frame 7, through the No. 1 threaded rod 8, causes the extension plate to vertically raise and lower the fixing plate 12, positioning the sampling cylinder 17 to the target liquid level. Then, simultaneously rotating the No. 3 handles 15 on both sides of the fixing plate 12 drives the clamping block 16 to firmly center the sampling cylinder 17, ensuring a vertical position for easy observation. During operation, quantitative sampling is performed using the pull rod 19 in conjunction with the transparent sampling cylinder 17 with graduations 18. Then, simultaneously rotating the No. 3 handle removes the sampling cylinder 17 and tilts it so that the sample can be poured into the threaded storage box 21. Finally, the storage box 21 is threadedly connected to a storage cap 23 at the center of its upper surface. The threaded connection between the storage box 21 and the storage cap 23 temporarily seals the liquid within the storage box 21, thus reducing the risk of contamination of the liquid inside the sampling cylinder 17.
