[0002] Drug sampling and testing refers to the process of randomly selecting a certain number of samples from multiple batches of products during the drug production process for quality testing and analysis. Its main purpose is to ensure that the quality of drugs meets the standards and to promptly identify and resolve potential quality problems. Specialized equipment is required for drug sampling.
[0003] Existing laboratory drug testing sampling devices use reaction vessels, which are filled with drugs and tested through reactions such as heating. However, the reaction vessels are positioned by pressing down, which causes shaking during use and leads to unstable positioning. Utility Model Content
[0004] The purpose of this invention is to provide a sampling device for laboratory drug testing to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for laboratory drug testing, comprising a reaction chamber, a support sleeve fixedly connected to the top of the reaction chamber, an extension cover abutting the top of the support sleeve, a reaction vessel fixedly connected to the inner side of the extension cover near the interior of the reaction chamber, a fixing sleeve fixedly connected to the outside of the extension cover, a fixing block abutting the inside of the fixing sleeve, a pushing block fixedly connected to the bottom of the fixing block, the pushing block slidably connected to the top of the reaction chamber, a spring fixedly connected to the side of the pushing block away from the fixing sleeve, and the end of the spring away from the pushing block fixedly connected to the outside of the support sleeve.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model provides a technical solution: such as Figure 1 - Figure 6The sampling device for laboratory drug testing shown includes a reaction chamber 1, a support sleeve 3 fixedly connected to the top of the reaction chamber 1, an extension cover 7 abutting the top of the support sleeve 3, a reaction vessel 2 fixedly connected to the inside of the extension cover 7 near the inside of the reaction chamber 1, a fixing sleeve 8 fixedly connected to the outside of the extension cover 7, a fixing block 6 abutting the inside of the fixing sleeve 8, a pushing block 4 fixedly connected to the bottom of the fixing block 6, the pushing block 4 slidably connected to the top of the reaction chamber 1, a spring 5 fixedly connected to the side of the pushing block 4 away from the fixing sleeve 8, the end of the spring 5 away from the pushing block 4 fixedly connected to the outside of the support sleeve 3, a sliding groove 9 opened inside the pushing block 4, a limiting rod 10 slidably connected inside the sliding groove 9, the limiting rod 10 is located inside the spring 5, and one end of the limiting rod 10 is fixedly connected to the outside of the support sleeve 3.
[0021] During operation, the reaction vessel 2 is placed inside the reaction chamber 1 using the extension cover 7. The fixing sleeve 8 secures the extension cover 7, allowing the spring 5 to push the push block 4 from outside the support sleeve 3. This causes the fixing block 6 to engage with the inside of the fixing sleeve 8, thus stably positioning the reaction vessel 2 inside the reaction chamber 1. When disassembling the reaction vessel 2, pushing the push block 4 compresses the spring 5, causing the push block 4 to slide outside the limit rod 10 via the sliding groove 9. This allows the fixing block 6 to disengage from the fixing sleeve 8, enabling the reaction vessel 2 to be removed from the reaction chamber 1. This achieves rapid positioning of the reaction vessel 2, solving the problem of unstable positioning caused by shaking during application when the reaction vessel 2 is positioned by pressing down, and improving the stability of the reaction vessel 2 during positioning.
[0022] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 In the diagram, a pressing block 11 is fixedly connected to the end of the pushing block 4 away from the spring 5. The pressing block 11 is slidably connected to the top of the reaction chamber 1. A base platform 13 is fixedly connected to the bottom of the reaction chamber 1. A telescopic rod 14 is fixedly connected to the top of the base platform 13 near the reaction chamber 1. A cover plate 15 is fixedly connected to the top of the telescopic rod 14. A detection component is set at the bottom of the cover plate 15 near the top of the reaction chamber 1. The detection component includes a sampling tube 12. The sampling tube 12 is fixedly connected to the bottom of the cover plate 15. The end of the sampling tube 12 away from the cover plate 15 is set inside the reaction vessel 2. A connecting cover 17 is fixedly connected to the outside of the sampling tube 12 near the reaction vessel 2. A sealing cover 16 is fixedly connected to the bottom of the connecting cover 17. The sealing cover 16 is slidably connected to the inside of the reaction vessel 2 near the top.
[0023] During operation, pressing block 11 can control the pushing block 4 to slide outside the limiting rod 10, making it easier to remove the reaction vessel 2 from the reaction chamber 1. The base 13 can stably fix the reaction chamber 1 and the telescopic rod 14, allowing the telescopic rod 14 to control the lifting and lowering of the cover plate 15, thus ensuring that the sampling tube 12 can be tested inside the reaction vessel 2. When the sampling tube 12 is sampling and testing inside the reaction chamber 1, the connecting cover 17 and the sealing cover 16 can also position the reaction vessel 2, ensuring the stability of the liquid reaction inside the reaction vessel 2 and improving the stability of the testing and sampling.
[0024] Working principle: The reaction vessel 2 is placed inside the reaction chamber 1 using the extension cover 7. The fixing sleeve 8 secures it to the extension cover 7, allowing the spring 5 to push the pushing block 4 from outside the support sleeve 3. This causes the fixing block 6 to engage with the inside of the fixing sleeve 8, thus stably positioning the reaction vessel 2 inside the reaction chamber 1. When disassembling the reaction vessel 2, pushing the pushing block 4 compresses the spring 5, causing it to slide outside the limit rod 10 via the sliding groove 9. This allows the fixing block 6 to disengage from the fixing sleeve 8, enabling the reaction vessel 2 to be removed from the reaction chamber 1. This achieves rapid positioning of the reaction vessel 2, solving the problem of positioning the reaction vessel 2 by pressing down during the reaction process. The application of tank 2 causes shaking, leading to unstable positioning of the reaction tank 2. To improve the stability of the reaction tank 2 during positioning, the pressing block 11 can be used to control the sliding of the pushing block 4 outside the limiting rod 10, making it easier to remove the reaction tank 2 from the reaction chamber 1. The base platform 13 can stably fix the reaction chamber 1 and the telescopic rod 14, allowing the telescopic rod 14 to control the lifting and lowering of the cover plate 15, thereby ensuring that the sampling tube 12 can be tested inside the reaction tank 2. When the sampling tube 12 is sampling and testing inside the reaction chamber 1, the connecting cover 17 and the sealing cover 16 can also position the reaction tank 2, ensuring the stability of the liquid reaction inside the reaction tank 2 and improving the stability of the testing and sampling.
