Description

Technical Field

[0001] The utility model relates to the technical field of drug extraction equipment, in particular to a drug extraction device for microbial detection of Chinese herbal medicine slices. Background Art

[0002] Maintaining sample purity and accuracy is essential for ensuring reliable test results during microbiological testing. However, the sealing limitations of traditional drug extraction devices have become a significant constraint on test accuracy. Poor sealing allows microbial samples to leak, wasting valuable sample resources and potentially harming operators and the environment. Furthermore, the intrusion of external contaminants can contaminate samples, further impacting the accuracy of test results.

[0003] Moreover, traditional drug extraction devices have obvious deficiencies in the design of disassembly and assembly between the sampling tube and the sampling tube. These devices often require operators to use special tools and go through multiple tedious steps to complete disassembly and assembly, which not only increases the burden on the operator, but may also cause errors and damage during the disassembly and assembly process. In addition, the stability of the connection between the sampling tube bodies is also a problem that needs to be solved urgently. During transportation, storage or use, the sampling tube body is prone to accidental detachment due to loose connection, which may not only cause leakage of microbial samples, but also contaminate other samples or the environment, and have a serious impact on the test results. For this reason, we provide a drug extraction device for microbial detection of Chinese herbal medicine slices. Utility Model Content

[0014] Beneficial effects of the utility model:

[0023] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0024] Example

[0025] like Figure 1-Figure 5As shown, a drug extraction device for detecting microorganisms in Chinese herbal medicine slices, proposed in one embodiment of the present invention, is mainly composed of a sampling tube body 1 and a sampling tube body 2, which are fastened together to form a holding cavity for accommodating microorganisms. A piston block 3 is provided on the inner wall of the holding cavity. The piston block 3 is connected to an external operating handle via a pull rod 5 to facilitate its up and down movement within the holding cavity. In order to prevent the sampling tube body 1 and the sampling tube body 2 from detaching after being fastened together, an anti-detachment mechanism is designed. The mechanism includes a limiting arc plate 6 and a sleeve ring 7 fixed to the periphery of the sampling tube body. The U-shaped arc plate 8 at the upper end of the sleeve ring 7 is plugged into the plug-in arc plate 9 at the lower end, and a reset structure maintains a stable connection state. The reset structure consists of a strip-shaped placement groove 10, a vertical fixing rod 11, a spring 12, and a sliding sleeve 13. When the plug-in arc plate 9 is inserted into the U-shaped arc plate 8, the sliding sleeve 13 automatically resets under the action of the spring 12, ensuring that the two are tightly connected.

[0026] Among them, the sampling tube body 1 and the sampling tube body 2 2 can be firmly kept together after being buckled, effectively preventing the leakage or contamination of microbial samples caused by accidental separation during use.

[0027] Furthermore, the design of the disassembly and assembly components is intended to facilitate the disassembly and assembly operations between the sampling tube 4 and the sampling tube body 1 and the sampling tube body 2 2. An iron ring piece 14 is fixed to the periphery of the sampling tube 4, and a magnetic block 15 is embedded in the lower ends of the sampling tube body 1 and the sampling tube body 2 2. At the same time, a socket piece 16 is also fixedly connected to the lower ends of the sampling tube body 1 and the sampling tube body 2 2, which is used to clamp the periphery of the iron ring piece 14. When the sampling tube 4 needs to be installed, it only needs to be inserted into the sampling tube body and rotated slightly, and the iron ring piece 14 will be firmly adsorbed by the magnetic block 15, realizing quick installation. When disassembling, it can be easily completed by simply overcoming the magnetic attraction force.

[0028] Among them, the design of the disassembly and assembly components simplifies the disassembly and assembly process between the sampling tube 4 and the sampling tube body, improves the operating efficiency, and ensures the stability and reliability during the disassembly and assembly process.

[0029] Furthermore, a strip-shaped mounting groove 10 is formed on the inner sidewall of the U-shaped curved plate 8, and a vertical support rod 11 is installed within the groove. A spring 12 and a sliding sleeve 13 are mounted around the outer periphery of the vertical support rod 11. The sides of the sliding sleeve 13 are fixedly connected to the sides of the plug-in curved plate 9. When the plug-in curved plate 9 is inserted into the U-shaped curved plate 8, the sliding sleeve 13 is squeezed and slides along the vertical support rod 11, compressing the spring 12. When the plug-in curved plate 9 is fully inserted, the spring 12, under the action of its restoring force, pushes the sliding sleeve 13 back into place, thereby maintaining a tight connection between the plug-in curved plate 9 and the U-shaped curved plate 8.

[0030] The reset structure ensures a secure connection between the U-shaped arc plate 8 and the plug-in arc plate 9, and automatically resets during assembly and disassembly, improving the overall performance and service life of the device. In the reset structure, one end of the spring 12 is fixedly connected to the end wall of the strip-shaped receiving groove 10, while the other end is fixedly connected to one end surface of the sliding sleeve 13. This connection ensures that the spring 12 can stably store energy when compressed and quickly release energy to push the sliding sleeve 13 back to its original position when needed.

[0031] Furthermore, to further enhance the sealing performance between sampling tube body 1 and sampling tube body 2, a sealing structure is designed. This structure includes a sealing insert 17 fixed to the open end of sampling tube body 1 and a sealing slot 18 provided in the surface of the open end of sampling tube body 2. When sampling tube body 1 and sampling tube body 2 are fastened together, sealing insert 17 inserts into sealing slot 18, achieving a tight seal through an interference fit.

[0032] The interference fit between the sealing insert 17 and the sealing slot 18 is achieved by precisely controlling their size and shape. During the design and manufacturing process, the difference between the outer diameter of the sealing insert 17 and the inner diameter of the sealing slot 18, or the interference fit, is strictly controlled to ensure sufficient friction during insertion to maintain a seal. This interference fit ensures a tight connection and seal between the sealing insert 17 and the sealing slot 18, effectively preventing leakage of microbial samples.
