Laboratory equipment usually needs to adapt to different experimental requirements, including culture dishes of different sizes and different culture conditions; 2. The device does not mention real-time monitoring or data recording functions, which means that researchers may not be able to observe the experimental process in real time or accurately record key data, thereby affecting the accuracy and traceability of the experimental results. For this reason, we propose a device for testing laboratory bacterial culture media. Utility Model Content

[0029] The intermittent rotating device 9 is arranged inside the base 2. By arranging the intermittent rotating device 9 inside the base 2, the automatic and intermittent rotation function of the rotating disk 5 is realized. This design not only ensures that the bacteria in the culture dish 6 can be heated evenly, thereby improving the culture efficiency, but also reduces manual intervention and improves the automation level of the experiment.

[0030] The buckle 10 is provided on the rotating disk 5 to fix the culture dish 6. The buckle 10 is provided on the rotating disk 5 to firmly fix the culture dish 6, effectively preventing the culture dish 6 from shifting or tipping over due to vibration or external force during the culture process, ensuring the continuity and accuracy of the experiment, and facilitating the rapid installation and removal of the culture dish 6.

[0031] Furthermore, a detection camera 7 is fixedly installed on the side of the constant temperature box 1 facing away from the observation window. The detection camera 7 is installed on the side of the constant temperature box 1 facing away from the observation window, which realizes real-time monitoring of the bacterial culture process. This innovation not only makes it convenient for researchers to remotely observe the growth status of bacteria, but also can record key information in the culture process, providing valuable data support for subsequent scientific research analysis.

[0032] Furthermore, a fixing rod 8 is fixedly installed inside the base 2 , and an intermittent rotating device 9 is provided on one side of the base 2 close to the fixing rod 8 .

[0033] Furthermore, the intermittent rotating device 9 includes a motor 17, which is fixedly mounted on the bottom end of the base 2 near the fixed rod 8. A fixed disk 13 is fixedly mounted on the output shaft of the motor 17, and a round pin 14 is fixedly mounted on the top side of the fixed disk 13. A bow plate 15 is fixedly mounted on the top side of the fixed disk 13 away from the round pin 14. By installing the fixed rod 8, the motor 17 and the fixed disk 13, the round pin 14 and the bow plate 15 connected thereto inside the base 2, a precise transmission mechanism is formed. The mechanism realizes precise intermittent rotation of the rotating disk 5 through the cooperation of the arc-shaped slot of the groove wheel 16 and the bow plate 15, and the cooperation of the straight slot and the fixed ear 12, thereby further improving the accuracy and repeatability of the experiment.

[0034] Furthermore, a rotating shaft 18 is rotatably installed on the top of the fixed rod 8, and a groove wheel 16 is fixedly installed in the middle of the rotating shaft 18. The interior of the groove wheel 16 is provided with an arc-shaped groove, and a straight groove is provided inside the arc-shaped groove. The arc-shaped groove of the groove wheel 16 corresponds to the bow plate 15, and the straight groove of the groove wheel 16 corresponds to the fixed ear 12. The rotating disk 5 is fixedly installed on the top of the rotating shaft 18. The design of fixing the rotating disk 5 on the top of the rotating shaft 18 ensures the stable rotation and carrying capacity of the rotating disk 5. This structure not only improves the overall stability of the equipment, but also provides a reliable support platform for the culture dish 6, which is conducive to the stable culture of bacteria.

[0035] Furthermore, a group of fixing grooves 11 are fixedly installed around the top of the rotating disk 5, and multiple groups of fixing grooves 11 are provided with multiple groups of sliding grooves. The interiors of the multiple groups of fixing grooves 11 are slidably clamped with culture dishes 6, and a group of buckles 10 are fixedly installed on both sides of the multiple groups of fixing grooves 11. The fixing grooves 11 arranged around the top of the rotating disk 5 and the sliding groove design inside them, combined with the buckles 10, realize the flexible placement and fixation of the culture dishes 6. This design is not only suitable for culture dishes of different sizes, but also facilitates the rapid adjustment of the position and number of culture dishes according to experimental requirements, thereby improving the flexibility and efficiency of the experiment.

[0036] Furthermore, a group of fixing ears 12 are fixedly installed on both sides of the bottom end of the culture dish 6, and the culture dish 6 is slidably engaged with the inside of the fixing groove 11 through the fixing ears 12. The fixing ears 12 set on both sides of the bottom end of the culture dish 6 cooperate with the sliding groove inside the fixing groove 11 to achieve a stable sliding engagement of the culture dish. This design not only simplifies the installation process of the culture dish, but also enhances the stability of the culture dish during the rotation process, avoiding experimental failure due to loosening or falling off.

[0037] Working principle: Before the experiment begins, researchers initialize the equipment through the control computer 4, including setting parameters such as the temperature of the constant temperature box 1, the rotation interval and time of the rotating disk 5, and placing the bacterial culture medium to be tested in the culture dish 6. The culture dish is slid and snapped into the fixed groove 11 at the top of the rotating disk 5 through the fixed ear 12 at the bottom of the culture dish. The culture dish 6 is then firmly fixed with the buckle 10. The constant temperature box 1 maintains the set constant temperature, providing a stable growth environment for bacteria. The observation window allows researchers to visually view the conditions in the constant temperature box without disturbing the growth of bacteria. The motor 17 is started under the control of the control box 3, and drives the fixed disk 13 to rotate through the output shaft. The round pin 14 and the bow plate 15 on the fixed disk 13 are connected with the arc groove and the groove wheel 16. The linear slots cooperate to realize the intermittent rotation of the groove wheel 16. The groove wheel 16 drives the rotating disk 5 and the culture dish 6 thereon to rotate automatically and intermittently through the rotating shaft 18, ensuring that the bacteria can be heated evenly and improving the culture efficiency. The detection camera 7 captures the growth status of bacteria in the constant temperature box 1 in real time and transmits the video signal to the control computer 4. The software on the control computer 4 processes and records the video signal, providing valuable data support for subsequent scientific research analysis. When the experiment reaches the preset time or conditions, the equipment automatically stops rotating and heating. Researchers view the recorded data through the control computer 4 to analyze the growth of bacteria and the performance of the culture medium. According to the analysis results, researchers can adjust the experimental conditions or optimize the culture medium formula to improve the experimental efficiency and accuracy.
