The air duct guides the air into each support cross beam, and the air inside the support cross beam is discharged to the outside of the support cross beam through the exhaust holes. At this time, the air from the outside of the support cross beam will come into contact with the test tubes fixed on the installation frame, so that the air outside the test tubes is driven by the air inside the support cross beam, causing the air to flow outside the test tubes, thereby preventing the accumulation of volatile chemical substances outside the test tubes.

[0034] Through holes 9 are provided horizontally in the middle of the central block 8 and the connection blocks 7, and a reserved hole 10 is provided vertically in the middle of the central block 8. The central block 8 and the connection blocks 7 are both connected to the outside of the support crossbeam 2 through the through holes 9, and the central block 8 is connected to the outside of the duct 4 through the reserved hole 10.

[0037] Embodiment 2:

[0038] Based on Embodiment 1, its specific working principle is as follows:

[0039] For this detachable ventilation-type central reagent rack, when the reagent rack is in a ventilated state, the suction fan 5 is in an operating state. The suction fan 5 sucks the outside air into the air duct 4. Since the connection between the air duct 4 and the suction fan 5 is a funnel-shaped structure, the flow rate of the air entering the air duct 4 increases. The air duct 4 guides the air into each support crossbeam 2, and the air inside the support crossbeam 2 is discharged to the outside of the support crossbeam 2 through the exhaust holes 6. At this time, the air outside the support crossbeam 2 will come into contact with the test tubes fixed to the mounting rack 12, causing the air outside the test tubes to be driven by the air inside the support crossbeam 2, so that the air flows outside the test tubes, thereby preventing the accumulation of volatile chemical substances outside the test tubes. At the same time, the air is split through the exhaust holes 6 and the air duct 4, enabling a single suction fan 5 to provide a uniform ventilation effect for multiple test tubes;

[0040] The entire mounting rack 12 is installed between the clamping grooves 11 on both sides of the central block 8 and the connecting block 7 through the connecting strips 13 on both sides. At this time, by pulling the handle 14 connected to the connecting strip 13, the user can separate the entire mounting rack 12 from the central block 8 and the connecting block 7 by pulling the handle 14, which is convenient for carrying multiple test tubes and facilitating batch processing of the test tubes;

[0041] When the test tube is installed inside the mounting rack 12, the test tube will penetrate through the upper load-bearing plate 15 and be snap-fitted inside the fixed ring 16 of the upper load-bearing plate 15. At the same time, the lower end of the test tube will be snap-fitted inside the base 17 of the lower load-bearing plate 15. Since there are positioning blocks 1602 extending towards the inside of the positioning ring 1601, the positioning blocks 1602 always fit against the outside of the test tube, and test tubes with different diameters can be fixed through the deformation of the positioning blocks 1602.
