In this embodiment, when the dissolution instrument operating cabinet is needed to perform an experiment, the dissolution instrument is first installed in the operating cabinet body 1, and the dissolution instrument is placed in the dissolution instrument placement area 2, and then the drive motor 9 is started, and the output end of the drive motor 9 drives the bidirectional screw 6 to rotate, and the bidirectional screw 6 drives the moving block 7 from both ends to the middle during the rotation process, and the moving block 7 drives the clamping plate 8 to move toward the direction of the dissolution instrument until it contacts the left and right side walls of the dissolution instrument, stops the operation of the drive motor 9, and then makes the two groups of sliders 13 slide on the slide rails 12, so that the slider 13 moves toward the front end face of the dissolution instrument, until the slider 13 drives the limiting plate 14 to contact the front end face of the dissolution instrument, limits the dissolution instrument, prevents the dissolution instrument from moving back and forth, and facilitates the adaptive fixation of different types of dissolution instruments.

[0028] In actual use, it is further convenient to clamp reagent tubes of different types. In this embodiment, the clamping assembly includes a fixed block 17, a spring 18, a limit block 19, a limit column 20 and a clamp 21. The fixed block 17 is installed on the left and right side walls of the reagent placement groove 16. Two groups of cylindrical grooves 22 are symmetrically opened in the fixed block 17. A through hole 23 is opened on the side of the circular groove close to the reagent placement groove 16. The spring 18 is installed in the cylindrical groove 22. The limit block 19 is installed on one end of the spring 18 close to the through hole 23, and the limit column 20 is installed on the side of the limit block 19 away from the spring 18.

The connector 26 is connected to the waste liquid collection bucket 25 through a waste liquid collection tube 27. The waste liquid collection bucket 25 is connected to the dissolution instrument through the connector 26 at the end of the waste liquid collection tube 27, and is used to collect waste liquid generated by the dissolution instrument.

[0031] In actual use, it is further convenient to understand the working condition of the dissolution instrument. In this embodiment, the control panel 4 is arranged directly above the operation cabinet body 1. The control panel 4 is used to control the operating parameters of the dissolution instrument and the environmental conditions in the operation cabinet body 1. The control panel 4 can be implemented through a touch screen or buttons, which is convenient for users to operate. At the same time, the control panel 4 can also display the working status, operating parameters and other information of the dissolution instrument, which is convenient for users to understand the working condition of the dissolution instrument. The waste liquid collection barrel 25 can be provided with a liquid level sensor. When the waste liquid in the waste liquid collection barrel 25 reaches a certain liquid level, an alarm can be issued through the control panel 4 to remind the user to dispose of the waste liquid in time.

[0032] In actual use, the sealing of the operation cabinet body 1 is further ensured. In this embodiment, a cabinet door 28 is provided at the front end of the operation cabinet body 1. Magnetic sealing strips 29 are fixedly provided on the four edges of the inner surface of the cabinet door 28. The cabinet door 28 is adsorbed to the operation cabinet body 1 through the magnetic sealing strip 29. When the cabinet door 28 is closed, the cabinet door 28 is adsorbed to the operation cabinet body 1 through the magnetic sealing strip 29, which can isolate the medicine in the dissolution instrument from the air, avoid oxidation and degradation of the medicine, improve the detection accuracy of the dissolution rate of the medicine, and facilitate people to use.

[0033] In actual use, the sealing performance of the reagent placement area 3 is further ensured.
