1. A cabin door structure, comprising:
a sample inlet (2) arranged on a top cover (1), and
a cabin door (3) covering the sample inlet (2) from the outside,
wherein,
the cabin door (3) is provided with a protrusion (4) extending into the sample inlet (2) when the cabin door (3) is closed, a distance from an inner surface of the protrusion (4) to an inner surface of the top cover (1) is less than a thickness of a target panel (5);
an outer surface of the cabin door (3) is provided with a handle mechanism which comprises a handle (6), and a limiting mounting mechanism is arranged between the handle (6) and the cabin door (3) to restrict a maximum distance from the handle (6) to the cabin door (3) and enable the cabin door (3) to move within the maximum distance relative to the handle (6);
the limiting mounting mechanism comprises a connecting block (10) fixedly mounted on the outer surface of the cabin door (3), the connecting block (10) connects the handle (6) with the cabin door (3) in an upper and lower directions, limiting pins (11) are respectively arranged at both ends of the connecting block (10), an inner surface of the handle (6) is provided with a mounting groove (12) covering the connecting block (10), two side walls of the mounting groove (12) are respectively provided with limiting holes (13) corresponding to the limiting pin (11), the limiting pin (11) is provided with a limiting segment (11a) extending into the corresponding limiting hole (13), and a length of the limiting hole (13) in a direction perpendicular to the outer surface of the cabin door (3) is greater than an outer diameter of the limiting segment (11a) and the limiting segment (11a) is enabled to slide along the limiting hole (13) in the direction perpendicular to the outer surface of the cabin door (3);
a length of the limiting hole (13) in a direction parallel to the outer surface of the cabin door (3) and perpendicular to an axis of the limiting pin (11) is greater than the outer diameter of the limiting section (11a), and the limiting section (11a) is enabled to slide along the limiting hole (13) in the direction parallel to the outer surface of the cabin door (3) and perpendicular to the axis of the limiting pin (11), and
the connecting block (10) is configured to drive the cabin door (3) to slide relative to the handle (6) in front-rear and left-right directions parallel to the outer surface of the cabin door (3) and perpendicular to the outer surface of the cabin door (3) in an up-down direction so as to adjust the protrusion (4) to better enter the sample inlet.
