Referring to fig. 1 to 4, fig. 1 is a schematic perspective view of a darkroom assembly according to an embodiment of the present invention, fig. 2 is an exploded schematic view of the darkroom assembly in fig. 1, fig. 3 is a schematic sectional view of the darkroom assembly in fig. 1, fig. 4 is an enlarged schematic view of an area a in fig. 3, and the darkroom assembly according to the present invention is specifically described below with reference to fig. 1 to 3.

In some embodiments, the darkroom assembly comprises a darkroom 100 and an object stage 200, wherein the darkroom 100 is provided with a cavity 110 for accommodating a sample to be tested, and an opening 120 communicated with the cavity 110. The stage 200 includes a light shielding portion 210 and a bearing portion 220, and the light shielding portion 210 is connected to the bearing portion 220. The stage 200 is connected to the dark chamber 100 and can move relative to the dark chamber 100 to move at least a portion of the supporting portion 220 out of the cavity 110 from the opening 120, so as to realize sample feeding and discharging. The light shielding portion 210 is located outside the dark room 100, and when the stage 200 moves to a set position with respect to the dark room 100, the light shielding portion 210 can contact the dark room 100 to close the opening 120.

One of the dark room 100 and the light shielding portion 210 has a first protrusion 300, and the other has a first groove 400, and both the first protrusion 300 and the first groove 400 are arranged along the circumferential direction of the opening 120. When the light shielding portion 210 is in a state of closing the opening 120 of the darkroom 100, the first protrusion 300 can extend into the first groove 400, so as to prevent external light from entering the cavity 110.

Specifically, the darkroom 100 of the present embodiment is substantially a rectangular parallelepiped, and has a cavity 110 for accommodating a sample to be tested therein, and an opening 120 on one side (for example, the front side of fig. 1), wherein the opening 120 is communicated with the cavity 110 of the darkroom 100, and the sample to be tested can enter and exit the cavity 110 through the opening 120 and can completely enter the darkroom 100. When the opening 120 of the darkroom 100 is closed by the structure similar to the stage 200, the interior of the darkroom 100 is in a dark state, which is convenient for the detection device such as a photoelectric multiplying light amplifying device to detect the sample. The darkroom 100 and the detection device can be implemented by a conventional technique, and will not be described in detail.

The stage 200 includes a light shielding portion 210 and a carrying portion 220, and the carrying portion 220 is substantially rectangular parallelepiped and has a placing structure for placing a sample to be detected, for example, a receiving groove located on the upper side of the carrying portion 220 as shown in fig. 2. The light shielding portion 210 may be connected to one end of the bearing portion 220, such as the front end shown in fig. 2, and the light shielding portion 210 of the present embodiment is approximately a plate-shaped structure extending outward from the bearing portion 220. The stage 200 of the present embodiment is suitable for use with a card-like specimen, and it will be appreciated that the placement configuration can be adjusted to accommodate different specimens, depending on the shape of the specimen. When in the detection state, the part with the placing structure on the object stage 200 can completely enter the dark room 100; when a sample needs to be taken in or out, the part of the object stage 200 with the placing structure can extend out of the dark room 100 through the opening 120 of the dark room 100, so that a sample can be put in or taken out conveniently. It will be appreciated that the object table 200 may also be fully accessible within the dark room 100, in which case a dark room door may be provided to close the opening of the dark room 100.

The light shielding portion 210 and the darkroom 100 are connected by the first protrusion 300 and the first groove, and the first protrusion 300 and the first groove 400 are both disposed along the circumference of the opening 120, i.e., the first protrusion and the second protrusion are respectively an annular groove and an annular protrusion, thereby achieving all-directional light shielding. When the first protrusion 300 extends into the first groove 400, the gap at the connection between the light shielding portion 210 and the darkroom 100 is bent, so that the external light is more difficult to enter the cavity 110, which is helpful to improve the light shielding effect of the light shielding portion 210. The number of the first protrusions 300 and the number of the first grooves 400 may be one-to-one, and in this embodiment, it is understood that the number of the first protrusions 300 and the number of the first grooves 400 may also be two, three or other, and the greater the number of the first protrusions 300 and the number of the first grooves 400, the better the shading effect is.

Referring to fig. 5, fig. 5 is a schematic partial cross-sectional view of a connection between a light shielding portion and a darkroom in an embodiment of the present invention, in other embodiments, the first groove 400 is located on the light shielding portion 210, the first protrusion 300 is located on the darkroom 100, specifically, the first groove 400 is located on one side of the light shielding portion 210 facing the light shielding portion 210, such as the rear side of fig. 5, and the first protrusion 300 is located on one side of the darkroom 100 facing the light shielding portion 210, such as the front side of fig. 5, so that if the external light enters the cavity 110, the purpose of improving the light shielding effect can be achieved by bending the light shielding portion at least twice.

Referring to fig. 6, fig. 6 is a schematic partial cross-sectional view of a junction between a light shielding portion and a darkroom according to another embodiment of the present invention, in some other embodiments, a first groove 400 is located on the darkroom 100, a first protrusion 300 is located on the light shielding portion 210, and the light shielding portion 210 covers the first groove 400 in a state where the light shielding portion 210 is in the closed opening 120. Specifically, along the direction parallel to the light shielding portion 210, the light shielding portion 210 further has a circle of extension portion 211 outside the first protrusion 300, and the extension portion 211 exceeds the first groove 400, so that the light shielding portion 210 covers the first groove 400, and thus, if external light enters the cavity 110, the external light needs to be bent at least four times, so that the light shielding effect can be improved. The extension part 211 can be attached to the front side of the darkroom 100, so that the gap between the extension part 211 and the darkroom 100 can be reduced, and the shading effect can be further improved.

The first flexible member in this embodiment is provided along the circumferential direction of the opening 120, and is made of a flexible material (e.g., rubber) that does not transmit light, or the like.

Referring to fig. 4, in other embodiments, the first protrusion 300 is attached to at least one side of the groove wall of the first groove 400, so as to reduce a gap between the first protrusion 300 and the first groove 400, thereby improving the light shielding effect.
