The sterile cabinet is used to place test supplies and food to ensure the safety of the items and prevent them from being contaminated.

[0003] However, the existing sterile cabinets have the following problems when in use:

[0004] In our daily work in the laboratory, we often encounter situations where we need to place items of different sizes. However, the internal panels of existing sterile cabinets are fixed and cannot be moved, which makes it extremely inconvenient to place some large items. It is often difficult to find a suitable storage location because the internal space cannot be flexibly adjusted. At the same time, when it comes to categorizing items, the fixed panels also limit our ability to make a more reasonable layout based on the size and type of items.

[0005] The utility model can play the role of more reasonable layout and placement of objects according to their sizes and types. Utility Model Content

A slide groove 103 is provided on the front and rear sides of both ends, a screw hole 104 is provided on the left and right sides of the rear end of the cabinet 1, the slide groove 103 is slidably connected to the cross plate 2, and a baffle 201 is fixedly installed on the front of the cross plate 2. A slider 203 is fixedly installed on the front and rear sides of the left and right ends of the cross plate 2. The slider 203 is slidably connected to the slide groove 103. A fixed block 204 is provided on the left and right sides of the rear side of the upper end of the cross plate 2. A screw rod 205 is threadedly connected to the front of the fixed block 204. The screw rod 205 is threadedly connected to the screw hole 104. The fixed block 204 is arranged behind the positioning hole 202. The front and rear sides of the extension plate 404 are fixedly installed with a positioning rod 406. The positioning rod 406 Embedded in the positioning hole 202 for internal connection, when the cabinet is used to place items, the horizontal plate 2 installed inside the cabinet body 1 is slidably connected to the slide groove 103 on the front and rear sides of the left and right ends of the cabinet body 1 through the slider 203, so that the horizontal plate 2 can be flexibly moved inside the cabinet body, which is convenient for adjusting the upper and lower space layout. When the horizontal plate 2 is adjusted to a suitable position, it is rotated backward through the screw 205 threadedly connected to the fixing block 204 so that it is threadedly connected to the screw hole 104 to fix the horizontal plate 2 in the current position. If it is not necessary to place items in a classified manner, the vertical plate 4 is slid to the left and right sides of the horizontal plate 2 so that it fits the inner wall of the cabinet body 1 and the positioning rod 40 6 is embedded in the positioning hole 202, so that the vertical board 4 is fixed in the current position and cannot be moved, so that the horizontal board 2 can be used to place large items. If classified placement is required, first move the two horizontal boards 2 to a suitable height and then fix them. Then, pull out the extension board 404 from the positioning hole 202, pass through the accommodating cavity 402, and the extension board 404 will be received by the accommodating cavity 402. Then move the vertical board 4. After moving the vertical board 4 to a suitable position, release the extension board 404 from the accommodating cavity 402, so that the positioning rod 406 is embedded in the positioning hole 402, fix the vertical board 4 in the current position, and form different layouts with the horizontal board 2 to achieve separation and classified storage of different items.

[0025] In the embodiment of the present invention, a second slide groove 301 is provided on the inner side surface of the connecting plate 3, and the second slide groove 301 is slidably connected to the vertical plate 4. A second slider 401 is fixedly installed above the front and rear ends of the vertical plate 4, and the second slider 401 is slidably connected to the second slide groove 301. When it is necessary to move the vertical plate 4 to adjust the space layout inside the cabinet 1, the sliding connection between the second slider 401 and the second slide groove 301 enables the vertical plate 4 to slide on the connecting plate 3 to adjust the space layout inside the cabinet 1, which greatly improves the flexibility of the space layout inside the cabinet 1 and realizes the separation and classification of different items. When larger items need to be stored, the adjacent vertical plates 4 can be slid apart to expand the storage space; when the items are smaller and of more types, the number of vertical plates 4 can be increased, the intervals can be shortened, and more detailed classification can be achieved.

[0026] In the embodiment of the present invention, the front side of the vertical plate 4 is threadedly connected with a screw rod 2 403, and the front side of the extension plate 404 is provided with a plurality of screw holes 2 405, and the screw rod 2 403 is threadedly connected with the screw holes 2 405. When the extension plate 404 is needed to increase the height of the vertical plate to accommodate the storage of higher items, the extension plate 404 is pulled out, and then the screw rod 2 403 is rotated to connect it with the corresponding screw hole 2 405, so as to prevent the extension plate 404 from shaking or slipping during use, thereby providing stable support and separation for the items.

[0027] Working principle: When it is necessary to store items inside the cabinet 1, the cabinet door 101 is opened using the handle 102. The horizontal board 2 is slidably connected to the slide grooves 103 on the front and rear sides of the left and right ends of the cabinet 1 through the slider 203 inside the cabinet 1. This allows the horizontal board 2 to be flexibly moved up and down inside the cabinet 1, thereby facilitating the adjustment of the upper and lower space layout. When it is necessary to adjust the position of the horizontal board 2, the experimenter can manually push the horizontal board 2 so that it slides along the slide groove 103 to the appropriate height. When the horizontal board 2 is adjusted to the appropriate position, the screw 205 threadedly connected to the fixing block 204 is rotated backward so that it is threadedly connected to the screw holes 104 on the left and right sides of the rear end of the cabinet 1, thereby fixing the horizontal board 2 in its current position. This ensures that the horizontal board 2 does not move when placing items, ensuring stable storage of items. When there is no need to sort and place items, the vertical board 4 can be slid to the left and right sides of the horizontal board 2 through the second slide groove 301 on the connecting board 3, so that it fits the inner wall of the cabinet body 1. At this time, the positioning rod 406 on the extension plate 404 at the bottom of the vertical board 4 is embedded in the positioning hole 202 at the upper end of the horizontal board 2, so that the vertical board 4 is fixed in the current position and cannot be moved. Therefore, the horizontal board 2 can be used to place large items and fully utilize the space. When sorting and placing items, the two horizontal boards 2 are first moved to the appropriate height and fixed. Then, the extension board 404 is pulled out from the positioning hole 202. Since the extension board 404 is located in the accommodating cavity 402 at the bottom of the vertical board 4, the accommodating cavity 402 serves to store and protect the extension board 404 during the withdrawal process. Next, after moving the vertical plate 4 to the appropriate position, the extension plate 404 is released from the accommodating cavity 402, and the positioning rod 406 is embedded in the positioning hole 202, thereby fixing the vertical plate 4 in the current position. In this way, the vertical plate 4 and the horizontal plate 2 are matched to form different layouts, which can realize the separation and classification storage of different items. When the extension plate 404 is needed to increase the height of the vertical plate 4 to accommodate the storage of higher items, the extension plate 404 is pulled out from the accommodating cavity 402 at the bottom of the vertical plate 4, and then, by rotating the screw rod 2 403 threadedly connected to the front face of the vertical plate 4, it is threadedly connected to the corresponding screw hole 2 405 opened on the front face of the extension plate 404 to prevent the extension plate 404 from shaking or slipping during use, thereby providing stable support and separation for the items.
