A guide block 8 is assembled on the inner wall of the guide groove 7. The guide block 8 is fixedly connected to the side wall of the connecting plate 6. A sampling The tube 9 is assembled inside the sleeve 1. The outer wall of the bottom end of the sleeve 1 is provided with a thread and is connected to a connecting seat 10 through a thread. The inner wall of the connecting seat 10 is provided with a thread. A limiting plate 11 is installed on the bottom side of the connecting seat 10. The inner ring diameter of the limiting plate 11 is the same as the outer wall diameter of the sampling tube 9. A mounting plate 12 is installed on the bottom side of the limiting plate 11, and a reed 13 is installed on the mounting plate 12. When working, the existing sampling device directly puts the external sampling tube 9 into the beef extract peptone solid culture dish for culturing microorganisms in the process of sampling the microbial culture dish. Since dust is easily attached to the outer wall of the external sampling tube 9, Dust can easily damage the environment inside the beef extract peptone solid culture dish, resulting in greater contamination of the microbial culture dish. By placing the sleeve 1 above the microbial culture dish and rotating the knob 5, the screw rod 4 is driven to rotate. The screw rod 4 moves vertically downward during the rotation, and the screw rod 4 pushes the connecting plate 6 to move vertically downward. The connecting plate 6 pushes the sampling tube 9 to move vertically downward. The sampling tube 9 is pushed out of the sleeve 1, and then the sampling tube 9 is inserted into the beef extract peptone solid of the microbial culture dish. After the sample is loaded into the sampling tube 9, the knob 5 is rotated in the opposite direction, and the screw rod 4 drives the sampling tube 9 to move vertically upward. The sampling tube 9 is brought When the sample is pulled out from the microbial culture dish, beef extract peptone solids will be attached to the outside of the sampling tube 9. During the upward movement of the sampling tube 9, the reed 13 is in contact with the outer wall of the sampling tube 9, and the solids on the outer wall of the sampling tube 9 are scraped off, thereby cleaning the outer wall of the sampling tube 9. Finally, the sampling tube 9 is moved back into the sleeve 1 to achieve sampling of the microbial culture dish. This structure makes the sampling tube 9 built-in, and the outer wall of the built-in sampling tube 9 is relatively clean before sampling, thereby avoiding dust attached to the outer wall of the sampling tube 9 to damage the environment inside the beef extract peptone solid culture dish, which is beneficial to reducing the contamination of the sampling tube 9 to the microbial culture dish.

[0020] See also Figure 4-5 As shown, a plate groove 14 is provided on the side wall of the sleeve 1, and an assembly plate 15 is installed on the outer wall of the sleeve 1 at the plate groove 14. A slide groove 16 is provided in the assembly plate 15, and a sliding plate 17 is slidably installed in the slide groove 16. Two groups of springs 18 are installed on the sliding plate 17 and the inner wall of the slide groove 16.

The cover plate 24 is sleeved on the assembly plate 15. A rod groove 25 is opened on the floor of the assembly plate 15, and a push rod 26 is assembled in the rod groove 25. The push rod 26 is fixedly connected to the bottom side of the sliding plate 17; when working, after the existing sampling device samples the microbial culture dish, it is impossible to limit the sample inside the sampling tube 9. The movement of the sampling tube 9 is likely to cause the sample inside to fall off, so the sample inside the sampling tube 9 needs to be immediately sampled. The sampling tube 9 is moved back into the sleeve 1 after the sampling is completed. At this time, the bottom side of the sampling tube 9 moves to the top of the sealing plate 21. At this time, the sampling tube 9 on the side of the sealing plate 21 no longer blocks the sealing plate 21. Under the thrust of the two sets of springs 18, the two sets of springs 18 push the sliding plate 17 to move horizontally in the slide groove 16. The sliding plate 17 pushes the sealing plate 21 to move in the plate groove 14. The sealing plate 21 moves to the bottom side of the sampling tube 9, sealing the outlet of the sampling tube 9. The sampling tube 9 The sample inside will not fall off, and the sampling tube 9 can be carried to temporarily store the sample. When the sample inside the sample tube 9 needs to be collected, the push rod 26 is pushed, and the push rod 26 drives the sliding plate 17 to move, and the sliding plate 17 drives the sealing plate 21 to slide outward. The sealing plate 21 no longer blocks the bottom side of the sampling tube 9, and the sample inside the sampling tube 9 can be directly poured out. This structure limits the sample inside the sampling tube 9, so that the sampling tube 9 can carry the sample and move, which is conducive to improving the convenience of sample collection.

[0021] Working principle: In the process of sampling the microbial culture dish, the existing sampling device directly puts the external sampling tube 9 into the beef extract peptone solid culture dish for culturing microorganisms. Since dust is easily attached to the outer wall of the external sampling tube 9, the dust is easy to damage the environment inside the beef extract peptone solid culture dish, resulting in greater pollution to the microbial culture dish. By placing the sleeve 1 above the microbial culture dish, the knob 5 is turned to drive the screw rod 4 to rotate. The screw rod 4 moves vertically downward during the rotation process. The screw rod 4 pushes the connecting plate 6 to move vertically downward. The connecting plate 6 pushes the sampling tube 9 to move vertically downward. The sampling tube 9 is pushed out of the sleeve 1, and then the sampling tube 9 is inserted The beef extract peptone solid enters the microbial culture dish. After the sample is loaded into the sampling tube 9, the knob 5 is rotated in the opposite direction, and the screw 4 drives the sampling tube 9 to move vertically upward. The sampling tube 9 drives the sample to be pulled out of the microbial culture dish. The beef extract peptone solid will be attached to the outside of the sampling tube 9. During the upward movement of the sampling tube 9, the reed 13 is attached to the outer wall of the sampling tube 9, and the solid on the outer wall of the sampling tube 9 is scraped off, thereby cleaning the outer wall of the sampling tube 9. Finally, the sampling tube 9 is moved back into the sleeve 1 to achieve sampling of the microbial culture dish. This structure is achieved by building the sampling tube 9 in. Before sampling, the outer wall of the built-in sampling tube 9 is relatively clean, which avoids the dust adhering to the outer wall of the sampling tube 9 and the damage to the beef extract peptone solid. The environment inside the peptone solid culture dish is damaged, which is conducive to reducing the contamination of the sampling tube 9 to the microbial culture dish; after the existing sampling device samples the microbial culture dish, it is impossible to limit the sample inside the sampling tube 9. The movement of the sampling tube 9 easily causes the sample inside to fall off. Therefore, the sample inside the sampling tube 9 needs to be collected immediately, resulting in poor convenience of sample collection. After the sampling is completed, the sampling tube 9 moves back to the sleeve 1. At this time, the bottom side of the sampling tube 9 moves to the top of the sealing plate 21. At this time, the sampling tube 9 on one side of the sealing plate 21 no longer blocks the sealing plate 21. Under the thrust of the two sets of springs 18, the two sets of springs 18 push the sliding plate 17 in the slide groove 16. The sealing plate 21 moves horizontally inside the sampling tube 9, and the sliding plate 17 pushes the sealing plate 21 to move in the plate groove 14. The sealing plate 21 moves to the bottom side of the sampling tube 9 to seal the outlet of the sampling tube 9. The sample inside the sampling tube 9 will not fall off, and the sampling tube 9 can be carried to temporarily store the sample. When it is necessary to collect the sample inside the sample tube 9, the push rod 26 is pushed, and the push rod 26 drives the sliding plate 17 to move. The sliding plate 17 drives the sealing plate 21 to slide outward, and the sealing plate 21 no longer blocks the bottom side of the sampling tube 9, and the sample inside the sampling tube 9 can be directly poured out. This structure is limited by the sample inside the sampling tube 9, so that the sampling tube 9 can carry the sample to move, which is conducive to improving the convenience of sample collection.
