[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] In the description of this utility model, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example 1: Refer to Figures 1-5 A laboratory chemical reagent and auxiliary agent storage device includes a housing 1, and further includes: a rotating shaft 2, rotatably connected to the inner wall of the housing 1 via bearings; a placement plate 3 with a cavity structure, fixedly installed at equal intervals on the surface of the rotating shaft 2; wherein, a placement groove 4 is provided on the placement plate 3, and a limiting ring 41 corresponding to the placement groove 4 is provided above the placement plate 3, and a movable L-shaped rod 42 is fixed to one end of the limiting ring 41; two airbags 5 are respectively provided on the placement groove 4 and the limiting ring 41; and a squeezing member is installed on the placement plate 3 for adjusting the diameter of the placement groove 4 and the limiting ring 41.

[0025] In this invention, reagent bottles containing reagent additives can be placed on the placement plate 3 before use. Since the placement plate 3 is equipped with a placement groove 4 and a limiting ring 41, it is convenient to classify and place reagent bottles on multiple placement plates 3, which facilitates subsequent handling and identification by staff. The limiting ring 41 is designed to limit the middle of the placed reagent bottle, improving the stability of the bottle when placed. In actual use, the horizontal position of the limiting ring 41 can be adjusted according to the height of the reagent bottle. At the same time, the provided extrusion component can be manually inflated, causing the airbag 5 on the limiting ring 41 and the placement groove 4 to expand, thereby achieving flexible clamping and limiting of the outer wall of the placed reagent bottle, avoiding collision and damage during the handling and transportation of the box 1, and providing a good protective effect.

[0026] Example 2: Refer to Figures 1-5Similar to Embodiment 1, but further: the extrusion component includes a connecting pipe 61 fixed to the bottom surface of the placement plate 3, one end of the connecting pipe 61 is fixedly connected to a pressing part 62, a switching valve 63 is provided on the connecting pipe 61, one end of the switching valve 63 is fixedly connected to a gas supply hose 64, the L-shaped rod 42 has a cavity inside, one end of the gas supply hose 64 passes through the cavity inside the placement plate 3 and the L-shaped rod 42 and is connected to the airbag 5 on the limiting ring 41, the other end of the switching valve 63 is connected to a branch pipe 65, the multiple airbags 5 provided on the placement groove 4 are connected to each other through a connecting pipe 66, one end of the branch pipe 65 passes through the placement plate 3 and extends into the interior and is fixedly connected to one of the connecting pipes 66, a rubber pad is fixed to the bottom inner wall of the placement groove 4, and a semi-circular groove is provided on the axial surface of the rubber pad.

[0027] During operation, manually squeezing the pressing part 62 delivers gas through the gas delivery hose 64 to the air bladder 5 installed on the limiting ring 41, causing the air bladder 5 to inflate. This allows the air bladder 5 to better fit and limit the placement of the reagent bottle, preventing shaking. The gas delivery hose 64 has an opening at the top inner wall of the placement plate 3, allowing the L-shaped rod 42 to be adjusted for height without affecting the gas delivery stability of the hose 64. When it is necessary to inflate the air bladder 5 on the placement slot 4, the conversion valve 63 can be manually adjusted. The pressing part 62 is connected to the branch pipe 65. Pressing the pressing part 62 again will transport the gas to the air bag 5 installed on the placement tank 4 and make it expand. This will provide flexible limiting protection for the bottom of the reagent bottle placed in the placement tank 4, and improve the stability of the overall structure. The bottom inner wall of the placement tank 4 is fixed with a rubber pad. The axial surface of the rubber pad is provided with a semi-circular groove to better fit the bottom of the reagent bottle. The bottom of the reagent bottle is generally a round arc bottom, which provides shock absorption and protection for the bottom of the reagent bottle. The pressing part 62 is a rubber bag structure.

[0028] A connector 70 is mounted on one end of the L-shaped rod 42. A screwing block 71 is mounted on the surface of the connector 70. An adapter is provided on the surface of the screwing block 71. The adapter includes a threaded protrusion on the surface of the screwing block 71. An adjusting cylinder 72 is fixed on the surface of the placement plate 3. An internal thread groove is provided on the inner wall of the adjusting cylinder 72. The threaded protrusion is adapted to the internal thread groove. A door is rotatably connected to the surface of the box 1 via a hinge. A sealing strip is provided on the door.

[0029] When adjusting the height of the limiting ring 41, the screw block 71 is manually rotated. The screw block 71 is threadedly connected to the adjusting cylinder 72. The relative position of the screw block 71 and the adjusting cylinder 72 is adjusted, thereby adjusting the height of the limiting ring 41. This is suitable for storing longer reagent bottles. A sealing strip is provided on the door to facilitate sealing and protection of the inside of the box 1, reducing the impact of the external environment on the reagents inside the box 1. The connecting part 70 is a bearing.

[0030] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
