[0036] An adjustment assembly for the tray 20 is provided between the connecting plate 6 and the box body 1, and the adjustment assembly includes a fixing rod 13 symmetrically arranged on the outside of the adjustment frame 3;

[0037] The sensing system includes a door state sensing module 27 for continuously monitoring the opening and closing state of the cabinet door 2;

[0038] A fall detection sensor module 28 is used to detect the acceleration change of the box 1 in real time;

[0039] The signal processing module 29 is used to process and judge the signals transmitted by the door state sensing module 27 and the fall detection sensing module 28 in real time;

[0040] The control module 30 is used to send corresponding control instructions to the servo motor 23 according to the judgment result;

[0041] A first sliding groove 4 is provided on the outside of the adjusting frame 3, and a plurality of first sliding blocks 5 are slidably connected to the inner side of the first sliding groove 4, a connecting plate 6 is installed on one end of the first sliding block 5 located on the outer side of the first sliding groove 4, a second sliding groove 7 is provided on the side of the adjusting frame 3, the second sliding groove 7 is connected to the first sliding groove 4, and a plurality of second sliding blocks 8 are slidably connected to the inner side of the second sliding groove 7, an end of the second sliding block 8 close to the inner side of the first sliding groove 4 is fixedly connected to the first sliding block 5, a connecting rod 9 is installed on one end of the second sliding block 8 located on the outer side of the second sliding groove 7, a first handle 10 is installed on the end of the connecting rod 9, a second handle 12 is movably connected to the connecting rod 9 on the side of the first handle 10 close to the adjusting frame 3, and a spring 11 is installed on the sides of the first handle 10 and the second handle 12 close to each other;

[0042] The two fixing rods 13 are respectively installed on both sides of the second handle 12, and a plurality of fixing grooves 14 for limiting the fixing rods 13 are provided on the outer side of the adjustment frame 3, and the fixing grooves 14 are movably connected to the fixing rods 13. A third sliding groove 15 is provided on the outside of the connecting plate 6, and the sliding plate 16 is slidably connected to the inner side of the third sliding groove 15. The inner side of the connecting plate 6 is threadedly connected with a first fixing bolt 17 for fixing the sliding plate 16, and one end of the sliding plate 16 away from the connecting plate 6 is fixedly connected to the support plate 18. The sliding plate 16 is internally threadedly connected with a second fixing bolt 31 for fixing the tray 20, and a round rod 19 is installed on the outside of the support plate 18, and the round rod 19 is located at the axis of the tray 20 and is rotatably connected to the tray 20.

[0043] In this embodiment, when pathogenic microorganisms need to be cultured, the pathogenic microorganisms are first placed in the corresponding placement grooves 21 on the tray 20, and then the box body 1 provides a suitable environment for the culture work. If pathogenic microorganisms of different shapes and sizes are encountered, the height of the tray 20 needs to be adjusted for use. At this time, the first handle 10 at the corresponding position of the tray 20 can be held, and the second handle 12 can be pulled to move away from the adjustment frame 3. At this time, the spring 11 will contract, and when the second handle 12 moves, it will drive the fixing rod 13 to move to the outside of the fixing groove 14. At this time, the second sliding block 8 can slide along the second sliding groove 7, and at the same time drive the first sliding block 8 to move. The moving block 5 slides along the first sliding groove 4. When the first sliding block 5 slides, it drives the tray 20 to move up and down through the connecting plate 6, the sliding plate 16 and the supporting plate 18. When the tray 20 moves to a suitable position, the second handle 12 can be released. At this time, the spring 11 in the contracted state is reset, and the second handle 12 is driven to reset at the same time. When the second handle 12 is reset, the fixing rod 13 is driven to insert into the fixing groove 14 at the corresponding position, so that the height of the tray 20 after adjustment is fixed, so that the tray 20 can be adjusted and used according to the size of the pathogenic microorganisms placed therein, so that the space in the box body 1 can be more effectively utilized, and the capacity and efficiency of the box body 1 can be improved;

[0044] When it is necessary to take out the pathogenic microorganisms on the tray 20, first, the first fixing bolt 17 is used to release the fixing of the connecting plate 6 and the sliding plate 16, and then the sliding plate 16 can be slid along the third sliding groove 15 until the tray 20 is driven to move to the outside of the box body 1 through the support plate 18, until the tray 20 protrudes to one-third of the outside of the box body 1, and then the second fixing bolt 31 can be rotated to release the fixing of the tray 20 and the sliding plate 16. At this time, the pathogenic microorganisms to be taken can be rotated to a position protruding one-third of the outside of the box body 1, and there is no need to go deep into the interior of the box body 1 to take them, which is convenient for the staff to take them. Example

[0045] like Figure 1-8As shown, based on the first embodiment, the outer rotation of the tray 20 is connected with a rotating ring 32, and the fixed plate 22 is installed on the outer side of the rotating ring 32, and a plurality of tooth blocks 26 are installed on the inner side of the rotating ring 32. The servo motor 23 is installed on the outside of the tray 20, and the output shaft end of the servo motor 23 is installed with a rotating rod 24, and the end of the rotating rod 24 is installed with a gear 25 that can mesh with the tooth block 26. The door state sensing module 27 includes a door magnetic sensor and a signal conversion unit. The door magnetic sensor continuously monitors the opening and closing state of the box door 2, and the signal conversion unit converts the sensed state into an electrical signal, and the output indicates that the door is opened. The fall detection sensor module 28 includes an acceleration sensor, an A / D converter and a data processing unit. The acceleration sensor detects the acceleration change of the box 1. The A / D converter converts the analog signal into a digital signal. The data processing unit analyzes the acceleration data to determine whether the box 1 falls. The signal processing module 29 includes an input unit and a processing unit. The input unit receives signals from the door state sensing module 27 and the fall detection sensor module 28. The processing unit logically judges and processes the received signals. The control module 30 issues instructions to the servo motor 23 according to the signal of the signal processing module 29.

[0046] In this embodiment, the door state sensing module 27 is used to detect the opening and closing state of the box door 2, and the state information is converted into an electrical signal output. At the same time, the fall detection sensing module 28 is used to detect the acceleration change of the box body 1 in real time. Once it is determined that the box body 1 has fallen, a corresponding signal is output. If the fall detection sensing module 28 detects that the box body 1 has fallen, the control of the servo motor 23 is prohibited. If the fall detection sensing module 28 does not detect that the box body 1 has fallen, the signal processing module 29 can perform a logical judgment on the opening and closing of the box door 2 through the data of the door state sensing module 27 and the fall detection sensing module 28, and then the servo motor 23 is controlled to start through the control module 30. After the servo motor 23 is started, it drives the rotating rod 24 to rotate, and drives the gear 25 to rotate at the same time. Since the gear 25 is meshed with the tooth block 26, the rotating ring 32 can be driven to rotate through the gear 25 and the tooth block 26, and the fixed plate 22 can be driven to rotate at the same time.

[0047] If the door state sensing module 27 detects that the box door 2 is in the open state, the fixing plate 22 is separated from the pathogenic microorganisms on the placement groove 21. If the door state sensing module 27 detects that the box door 2 is in the closed state, the fixing plate 22 fixes the pathogenic microorganisms on the placement groove 21. In this way, the pathogenic microorganisms are prevented from being damaged by the collision of the box body 1 according to the opening and closing state of the box door 2. At the same time, it is convenient for the staff to take it, and the rotation and reversal of the servo motor 23 can be automatically controlled by the sensing system without human intervention, which greatly improves the degree of automation of the operation and reduces the error rate of human operation.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
