In some embodiments, the darkroom assembly comprises a darkroom 100, an object stage 200, a position limiting device 300 and a power device 400, wherein the darkroom 100 is provided with a cavity 110 for accommodating a sample to be tested and an opening communicated with the cavity. The stage 200 is used for carrying a sample to be tested, and the stage 200 and the dark room 100 can move relative to the dark room 100, so that at least a part of the stage 200 moves out of the cavity from the opening of the dark room 100. The limiting device 300 is used for limiting the movement of the object stage 200 in the set position towards the opening, and preventing the object stage 200 from sliding out accidentally. The power unit 400 can drive the stage 200 to move away from the set position after the stopper 300 releases the stopper, or can directly drive the stage 200 to move away from the set position, thereby releasing the stopper of the stage 200 by the stopper 300.

Specifically, the darkroom 100 of the present embodiment is substantially a rectangular parallelepiped, and has a cavity 110 therein, so as to accommodate a sample to be detected. One side (e.g., the front side of fig. 1) of the darkroom 100 has an opening, which is in communication with the cavity 110, through which a sample to be tested can enter and exit the cavity 110, and can completely enter the cavity 110. When the opening of the darkroom 100 is closed by the structure similar to the objective table 200, the interior of the darkroom 100 is in a dark state, which is convenient for the detection device such as a photoelectric multiplying and intensifying 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.

Referring to fig. 1 and 2, the darkroom 100 of the present embodiment includes a first housing 120 and a second housing 130, the first housing 120 is used for forming an upper sidewall, a left sidewall, a right sidewall and a rear sidewall of the darkroom 100, the second housing 130 is used for forming a lower sidewall of the darkroom 100, and after the first housing 120 and the second housing 130 are connected by a fastening member, a shading process is performed at the connection position to form the darkroom 100. It can be understood that the first housing 120 and the second housing 130 can be integrally connected by welding or the like, or the darkroom 100 can be directly manufactured by an integral molding process.

The stage 200 is substantially a rectangular parallelepiped, and has a placement structure for placing a sample to be detected, such as the receiving groove 210 shown in fig. 2, the stage 200 of the present embodiment is suitable for a card-shaped sample, and it can be understood that the placement structure can be adjusted according to different shapes of the sample to adapt to different samples. When in the detection state, the part with the placing structure on the object stage 200 can completely enter the dark room 100; when sample introduction or sample discharge is required, the portion of the object stage 200 having the placement structure may extend out of the case 400 through the openings of the dark room 100 and the case 400, so as to facilitate sample introduction or sample removal. 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.

Referring to fig. 2 to 4, the limiting device 300 can at least limit the one-way movement of the object stage 200, that is, when the object stage 200 is required to stay in the dark room 100, for example, in the inspection state or the standby state, the limiting device 300 can limit the movement of the object stage 200 toward the opening direction (for example, the forward direction in fig. 3), so as to prevent the object stage 200 from sliding out of the dark room 100 to affect the inspection or being damaged by the outside. In this embodiment, the set position refers to a position after the object stage 200 completely enters the dark room 100, for example, the object stage 200 is located in fig. 3.

The power unit 400 may be used to move the stage 200 so as to move the stage 200 away from the set position and release the restriction of the stage 200 by the stopper 300, or may be used to drive the stage 200 to a different position. The power device may adopt a well-known motor, an electric cylinder and the like, and will not be described in detail herein.

In this embodiment, when the object stage 200 is at the set position, the limiting device 300 can limit the object stage 200 to move toward the opening of the darkroom 100, so as to prevent the object stage 200 from sliding out accidentally.

Referring to fig. 2, in other embodiments, the position-limiting device 300 includes a first position-limiting portion 310 disposed on one of the darkroom 100 and the object stage 200, and a second position-limiting portion 320 disposed on the other. In this embodiment, the darkroom 100 is connected to the second position-limiting portion 320, and the stage 200 is connected to the first position-limiting portion 310. Specifically, the first position-limiting portion 310 is close to the rear side of the object stage 200, and the second position-limiting portion 320 is correspondingly close to the rear side of the darkroom 100, so that the moving range of the object stage 200 can be increased.

Referring to fig. 4 to 6, fig. 5 is a partial schematic view of the stage of fig. 1 connected to the first position-limiting portion, fig. 6 is a partial schematic view of the darkroom of fig. 1 connected to the second position-limiting portion, and only a part of the structure of the darkroom is hidden in fig. 6 to better show the second position-limiting portion, in other embodiments, the first position-limiting portion 310 includes a first protrusion 311 protruding toward the second position-limiting portion 320, the second position-limiting portion 320 includes a first elastic member 321, and a second protrusion 322 protruding toward the first position-limiting portion 310. The first protrusion 311 can contact with the second protrusion 322 along with the relative movement between the object stage 200 and the darkroom 100, and drives the second protrusion 322 to move so that the first protrusion 311 passes over the second protrusion 322, and the second protrusion 322 can be driven by the first elastic element 321 to reset after the first protrusion 311 passes over.

Specifically, the first position-limiting portion 310 is located on the lower surface of the stage 200 and is integrally connected to the stage 200. The second position-limiting part 320 is located on the upper surface of the second casing 130 of the darkroom 100 and is connected with the second casing 130 through a threaded fastener. The second protrusion 322 is located on the motion track of the first protrusion 311, and the bottom end of the first protrusion 311 is lower than the top end of the second protrusion 322, so that when the object stage 200 moves towards the dark room 100 to approach the set position, the first protrusion 311 will contact with the second protrusion 322; with further movement of the object stage 200, the first protrusion 311 drives the second protrusion 322 to move downward, so that the top end of the second protrusion 322 is lower than the bottom end of the first protrusion 311, and the first elastic element 321 deforms; after the stage 200 moves to the set position in the dark room 100, the first protrusion 311 goes over the second protrusion 322, and the second protrusion 322 is reset by the first elastic element 321. When no external force acts on the object stage 200, the first protrusion 311 will be blocked by the second protrusion 322, and the object stage 200 will be restricted by the second protrusion 322 to move toward the opening of the dark room 100. The second protrusion 322 of this embodiment can elastically move through the first elastic element 321, and by means of the power applied by the power device 400, the object stage 200 can automatically trigger the position-limiting device 300 to limit during the movement process, or can leave the set position to release the limitation of the position-limiting device 300, without human intervention.

Referring to fig. 4 and 5, in another embodiment, opposite sides of the first protrusion 311 are provided with inclined surfaces along a moving direction of the stage 200 (e.g., a front-back direction of fig. 5), specifically, the first protrusion 311 of this embodiment is substantially triangular, and the front side and the back side of the first protrusion 311 are provided with inclined surfaces, so that when the first protrusion 311 contacts the second protrusion 322 from the front side and the back side of the second protrusion 322, respectively, the first protrusion 311 can be guided by the inclined surfaces, and the second protrusion 322 is driven to move up and down by the movement of the first protrusion 311 along the front-back direction.

Referring to fig. 4 and 6, in other embodiments, the second protrusion 322 is provided with slopes on opposite sides thereof in a moving direction of the stage 200 (e.g., a front-back direction of fig. 6). Specifically, the second protrusion 322 of the present embodiment is substantially triangular, and the front side and the rear side of the second protrusion 322 have inclined surfaces, so that when the first protrusion 311 contacts the second protrusion 322 from the front side and the rear side of the second protrusion 322, respectively, the first protrusion 311 can be guided by the inclined surfaces, and the second protrusion 322 is driven to move in the up-down direction by the movement of the first protrusion 311 in the front-back direction.

The second protrusion 322 may further have a protruding arc surface, and the arc surface is located between the two inclined surfaces of the second protrusion 322 and is connected to the top ends of the two inclined surfaces, respectively. Due to the action of the first elastic element 321, in the process that the first protrusion 311 passes over the second protrusion 322, the top end of the second protrusion 322 is always in contact with the first protrusion 311, and the top end of the second protrusion 322 is provided with the protruded arc surface, so that the relative movement between the first protrusion 311 and the second protrusion 322 is smoother, and the second protrusion 322 can be prevented from scratching the first protrusion 311.

It can be understood that the first protrusion 311 and the second protrusion 322 may be provided with an inclined surface to achieve guiding, and as shown in fig. 4, the first protrusion 311 and the second protrusion 322 may also be provided with an inclined surface. In addition, a protruding arc surface may also be disposed on the first protrusion 311, and the arc surface is located between the two inclined surfaces of the first protrusion 311 and is connected to the bottom ends of the two inclined surfaces respectively.

Referring to fig. 4 and 5, in other embodiments, a side (e.g., a lower side in fig. 4) of the first protrusion 311 facing the second position-limiting portion 320 is provided with a first position-limiting groove 312. After the object stage 200 moves to the set position, the top end of the second protrusion 322 can extend into the first limit groove 312, and the front side and the rear side of the second protrusion 322 are respectively contacted with the groove wall of the first limit groove 312, so that the movement of the object stage 200 along the front-rear direction is limited, and the object stage 200 can stop at the set position.

It can be understood that, in this embodiment, the set position where the object stage 200 can stay may be a single position, or may be two, three or other numbers, for example, the limiting device 300 may limit the object stage 200 after the object stage 200 completely enters the dark room 100 and is in the detection state or the standby state, and after the object stage 200 extends out from the dark room 100 and is in the sample injection state or the sample discharge state, and at this time, the same number of first protrusions 311 may be provided corresponding to the position where the object stage needs to stay.

It can be understood that the first protrusion 311 may not be disposed on the object stage 200, and the first limiting portion 310 is a first limiting groove 312 disposed at a corresponding position, and the limiting function can also be achieved by adjusting the height of the second protrusion 322.

Referring to fig. 4 and 6, in other embodiments, the second limiting portion 320 includes a rotating member 323 and a rotating shaft 324, and the rotating member 323 is provided with a second protrusion 322.
