In this embodiment, as shown in fig. 10, for example, an end of the chute, which is close to the top of the housing, extends obliquely outward (i.e., along the outer side of the insertion direction of the cassette), and an end of the chute, which is close to the bottom of the housing, extends obliquely inward (i.e., along the inner side of the insertion direction of the cassette), so that the door 311 can move outward while sliding open and move inward while sliding closed, thereby further improving the tightness between the door 311 and the housing. Further, a handle or a pull groove is provided on the surface of the door 311 to facilitate the operator to operate the door 311. In addition, the sliding chute can be detachably provided with a sealing block (i.e. the left sliding chute sealing block 303 and the right sliding chute sealing block 301), and the sealing block can be detached first, so that the bearing roller 312 of the door 311 can be assembled into the sliding chute, and then the sealing block is assembled, so that the side edge of the sliding chute is closed.

As shown in fig. 10 and 11, in the present embodiment, the upper and lower sides of the mounting seat are provided with the first magnet 302, the upper and lower sides of the housing are provided with the second magnet 3021, and the first magnet 302 magnetically attracts the second magnet 3021, so that the door 311 is magnetically attracted and fixed relative to the housing. In this way, when the door 311 slides up and opens, the first magnet 302 on the upper side of the mounting seat is magnetically fixed with the second magnet 3021 on the upper side of the housing (for example, may be disposed on the top plate 100), so as to ensure that the door 311 is in an open state; when the door 311 slides down and closes, the first magnet 302 on the underside of the mounting seat is magnetically fixed to the second magnet 3021 on the underside of the housing (e.g., may be disposed on the clip guide 104 or the bottom plate 200) to ensure that the door 311 is in a closed state.

As shown in fig. 10, in this embodiment, the door 311 mechanism further includes a door lock rail 309 disposed on the top of the housing and a lock lever 306 disposed on the door lock rail 309, wherein the door lock rail 309 extends along the front and rear sides of the housing, and the lock lever 306 is movable relative to the door lock rail 309 toward a side near the cover 117 to slide the door 311 relative to the housing to stop the door 311 from being accidentally opened by the lock lever 306. Illustratively, as shown in fig. 10, a door lock mounting plate 307 and a slider 310 are provided at the top of the housing, a door lock rail 309 is slidably provided on the slider 310, and a door lock motor 308 described below may be mounted on the door lock mounting plate 307.

As shown in fig. 10, in this embodiment, the door 311 mechanism further includes a controller, and a reflection sensor 313, a door lock sensor 305 and a door lock motor 308 electrically connected to the controller, where the reflection sensor 313 is used to obtain a closing signal of the door 311, the door lock sensor 305 is used to obtain a position signal of the lock lever 306, the door lock motor 308 is in driving connection with the lock lever 306, and the controller is used to control the door lock motor 308 to drive the lock lever 306 to move along the door lock guide rail 309 according to the closing signal obtained by the reflection sensor 313 and the position signal obtained by the door lock sensor 305. In this way, when the door 311 slides down to close, the reflective sensor 313 is triggered, and the controller receives the closing signal obtained by the reflective sensor 313, so that the door lock motor 308 can be controlled to drive the lock lever 306 to move from the sensing position of the door lock sensor 305 (i.e. the natural state of the lock lever 306) along the door lock rail 309 towards the side close to the cover 117, so as to stop the sliding and opening operation of the door 311.

It should be noted that the above-mentioned controller may also be electrically connected to the above-mentioned temperature and humidity sensor 404, the refrigerating unit 402, the positioning sensor 217, the cart motor 207, the start position sensor 203, the end position sensor 208, the sheet taking motor 218, the zero position sensor 202, the last position sensor, etc. to control the process of obtaining signals from the above-mentioned sensors to perform corresponding actions, and those skilled in the art should understand the respective control logic according to the above-mentioned actions, which is not described in detail herein.

The embodiment of the application also provides a detection device, which comprises the reagent sheet 114 access device. Since the structure and advantages of the reagent sheet 114 accessing apparatus are described in detail in the foregoing embodiments, the description thereof is omitted herein.

The above description is only of the preferred embodiments of the present utility model and is not intended to limit the present utility model, but various modifications and variations can be made to the present utility model by those skilled in the art.
