[0035] like Figure 3As shown, the sample storage box 3 includes: a storage drawer 15, a plurality of baffles 16 arranged in the storage drawer 15, a drawer top plate 18 arranged above the storage drawer 15, a first electric push rod 19 arranged at the rear end of the storage drawer 15, and a pushing assembly 20 arranged below the storage drawer 15; a plurality of cooling fans 22 are arranged on the drawer top plate 18; the storage drawer 15 is used to accommodate and organize samples, and the storage drawer 15 can be automatically opened and closed by pulling out the samples for storage and removal through the action of the first electric push rod 19, thereby improving the usability. Convenience; the cooling fan 22 is used to circulate air and cool down the storage drawer 15, which helps to maintain a stable temperature inside the storage drawer 15. The baffle 16 is slidably connected to the bottom of the storage drawer 15, and the pushing component 20 pushes the movement of the baffle 16. The pushing component 20 includes: a plurality of second electric push rods 32; the second electric push rods 32 are connected to the baffle 16, and the second electric push rods 32 are located below the center of gravity of the baffle 16. The second electric push rods 32 push the baffle 16 upward so that the storage drawer 15 is separated into a plurality of storage chambers 17, thereby adjusting the size and shape of the storage space.

[0036] like Figure 4 and Figure 5 As shown, the storage drawer 15 is slidably connected to the drawer top plate 18, a slide plate 23 is provided on the storage drawer 15, and a slide groove 24 is provided on the drawer top plate 18; the storage drawer 15 can perform a smooth sliding opening and closing operation relative to the drawer top plate 18; the left and right ends of the baffle 16 are symmetrically provided with a locking mechanism, and the left and right inner walls of the drawer top plate 18 are provided with a locking groove 25, and the locking mechanism is slidably connected to the locking groove 25; the locking groove 25 enables the baffle 16 to move accordingly with the opening and closing of the drawer, and at the same time forms a firm connection between the baffle 16 and the drawer top plate 18, thereby ensuring the firmness and stability of the baffle 16 and the drawer top plate 18 during the movement, and avoiding loosening or falling off during use.

[0037] like Figure 5 , as shown in FIG. 6 , the engaging mechanism includes: a magnet slot 26, a first magnetic block 27 disposed inside the magnet slot 26, and a second magnetic block 28 disposed outside the magnet slot 26; the first magnetic block 27 and the second magnetic block 28 have opposite polarity directions on adjacent sides, and the first magnetic block 27 and the second magnetic block 28 produce a magnetic attraction effect, so that the first magnetic block 27 and the second magnetic block 28 are close to each other. The second magnetic block 28 is slidably connected in the baffle 16, and a clamping column 29 is fixedly connected to the outside of the second magnetic block 28. A through slot 30 is disposed at the left and right ends of the baffle 16, and the through slot 30 is slidably connected to the clamping column 29; an electromagnet bar 31 is disposed in the drawer top plate 18, and the electromagnet bar 31 is slidably connected to the magnet slot 26.

[0038] After power is turned on, the polarity of the electromagnet strip 31 and the adjacent side of the first magnetic block 27 is consistent, and the polarity of the electromagnet strip 31 and the adjacent side of the second magnetic block 28 is consistent. This causes a repulsive force to be generated between the first magnetic block 27 and the second magnetic block 28 that were originally close to each other and the electromagnet strip 31, so that the second magnetic block 28 slides outward inside the baffle 16, pushing the clamping column 29 to slide outward along the through slot 30, so that the clamping column 29 is clamped with the clamping slot 25, so that a firm connection is formed between the baffle 16 and the drawer top plate 18, so that the sample chambers are separated from each other. When power is not turned on, the electromagnet strip 31 has no magnetism, and the attraction effect between the first magnetic block 27 and the second magnetic block 28 causes the first magnetic block 27 and the second magnetic block 28 to approach each other. At this time, the second magnetic block 28 slides toward the inside of the baffle 16, and the clamping column 29 slides inward along the through slot 30. At this time, the clamping mechanism is separated from the clamping slot 25, and the baffle 16 slides downward.

[0040] When accessing samples, the control screen 6 is unlocked through NFC sensing or fingerprint recognition, and then the control screen 6 is used to input sample information to select the sample storage box 3 to be stored, and the rise of the baffle 16 is controlled by controlling the second electric push rod 32. The rise and fixation of the baffle 16 are achieved by controlling the power supply of the electromagnet, so that the storage room 17 with existing samples is separated from the storage room 17 to be placed, and the baffle 16 of the storage room 17 where the samples need to be accessed is lowered, and then the door lock is opened, and the first electric push rod 19 pushes out the storage drawer 15, and the storage room 17 stops after being exposed. After the laboratory staff accesses the samples, the cabinet door 2 is closed. At this time, the cooling fan 22 of the storage room 17 is started, and the negative pressure fan plate 5 is started to cool and ventilate the storage room 17 in contact with the outside, thereby achieving the discharge of external air.

[0041] When the utility model is used, the laboratory personnel unlock the door lock system 7 and the control screen 6 through NFC induction or fingerprint recognition, and verify the identity authorization to enter the laboratory monitoring device system. The laboratory personnel enter or select the corresponding sample information on the control screen 6 to determine the storage location and related operations. The laboratory personnel select the sample storage box 3 to be stored, and control the second electric push rod 32 to rise through the control screen 6, so that the baffle 16 is fixed at the required position and separated from the existing sample storage room 17. The electromagnet is controlled to be energized, and then the baffle 16 is controlled to be fixed, so as to separate the storage room 17 to be stored and the irrelevant storage room 17, so as to avoid the environment of the storage room 17 of the existing samples from being affected by the outside. The door lock is opened, and the first electric push rod 19 pushes the corresponding storage drawer 15 to slide out. After the laboratory personnel store and retrieve the samples, they close the drawer and the cabinet door 2. After the storage drawer 15 is closed, the cooling fan 22 and the negative pressure fan plate 5 are started to reduce the temperature in the storage room 17, keep the air fresh, and realize ventilation and exhaust to ensure the quality of the samples and environmental hygiene.

[0042] The above is based on the ideal embodiment of the utility model.
