Abstract: The disclosure provides a cabin door structure including a sample inlet arranged on a top cover and a cabin door mounted on an outside of the sample inlet. The cabin door is provided with a protrusion, and the protrusion extends inwards into the sample inlet when the cabin door covering on the sample inlet. A distance from an inner surface of the protrusion to an inner surface of the top cover is less than a thickness of a target panel. In the cabin door structure of the disclosure, the distance from the inner surface of the protrusion to the inner surface of the top cover is set to be less than the thickness of the target panel.

Abstract: The present application discloses a test tube rotating mechanism and a production-line sample conveying system. The test tube rotating mechanism includes: a first rolling structure and a second rolling structure, where the first rolling structure and the second rolling structure are distributed along the conveying direction of a conveying track, each of the outer side surfaces of the first rolling structure and the second rolling structure has a tangent point with the peripheral wall of any test tube holder on the conveying track to limit the movement of the test tube holder, and the rolling of the first rolling structure and the second rolling structure relative to the test tube holder cause the test tube holder to rotate; and a transmission structure, where the transmission structure drives the first rolling structure and the second rolling structure to move away from and approach the conveying track.

Abstract: A waste liquid suction mechanism, a reaction disc, and a sample analyzer are provided. The waste liquid suction mechanism includes: a driving assembly; a lifting assembly, performing lifting movement under the action of the driving assembly, where a guide block is disposed on the lifting assembly, and stroke positions of the lifting assembly include a trigger position and a release position located below the trigger position; a suction needle assembly, disposed on the lifting assembly and performing lifting movement along with the lifting assembly, and including a suction needle configured to suck waste liquid; and a collection assembly, disposed below the suction needle assembly, and including a rotary stopper configured to block or release the suction needle.
