Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a safely closed centrifugal cabin cover. Background Art

[0002] For example, the processing system including a weighing rocker arm module provided by publication number CN218115441U - Weighing rocker arm module and processing system including the same, discloses a centrifugal chamber with a hatch, which is used to accommodate the centrifugal chamber. The centrifugal chamber has an openable hatch, which is located on the top of the centrifugal chamber and is connected to the body of the centrifugal chamber in a flip-up manner to ensure the centrifugal effect and the safety of the user during the centrifugation process.

[0003] However, since the existing centrifuge compartment cover is made of an acrylic plate or a glass plate and has other components on it, the whole is heavy. When opening and closing the centrifuge compartment cover, a lot of force is required to control the compartment cover. During the process, it is easy to cause crushing or squeezing injuries to the user due to unstable control. Utility Model Content
