The inner walls of the two storage grooves 3 are rotatably connected to the side of the lower ends of the two telescopic rods 44 respectively. The upper ends of the two telescopic rods 44 are fixedly connected to the bottoms of the two ear plates 41 respectively. The side of the two ear plates 41 is fixedly connected to the side of the upper end of the sealing column 42. The diameter of the sealing column 42 is equal to the diameter of the storage groove 3. A sealing ring 43 is fixedly installed in the annular groove on the side of the lower end of the sealing column 42. A T-shaped handle rod 7 is fixedly installed in the middle of the top of the sealing column 42. The handle rod 7 allows people to The sealing column 42 can be conveniently pushed to rotate, which is convenient for use. The bottom of the sealing column 42 and the top of the support plate 8 are fixedly installed with a sponge pad 10. The sponge pad 10 can protect the culture dish with the culture medium to prevent the culture dish from being damaged. The sealing column 42 and the storage tank 3 are installed with a fixing mechanism 5. The storage tank 3 can be used to store the culture dish with the culture medium. The lifting and rotation of the sealing column 42 are achieved through the cooperation of the telescopic rod 44 and the rotating tank 45, thereby achieving the sealing and taking of the culture medium, so that the culture dish with the culture medium will not contact the culture medium in other storage tanks 3 when taking and placing, and cross infection can be avoided when one of the culture media is contaminated, thereby avoiding all the culture media from being contaminated, and improving the stability and safety of the culture medium during the storage process;

[0019] The fixing mechanism 5 includes a spring 51, a clamping block 52, a mounting groove 53 and a clamping groove 54. There are two mounting grooves 53. The two mounting grooves 53 are opened on the side of the upper end of the sealing column 42. The springs 51 are fixedly installed in the two mounting grooves 53. One end of the outer side of the two springs 51 is fixedly connected to the end surface of one end of the two clamping blocks 52. The two clamping blocks 52 are slidably installed in the two mounting grooves 53. Both sides of the top of the sealing column 42 are opened with grooves connected to the mounting grooves 53. The two clamping blocks 52 are close to the side of one end of the spring 51. A push plate 6 is fixedly installed on the surface, and the push plate 6 is located in the groove at the top of the sealing column 42.

One end of the outer side of the two card blocks 52 is provided with an inclined surface. The sealing column 42 can be fixed by the card block 52 and the spring cooperating with the card slot 54 to prevent the sealing column 42 from opening during the sealing process.

[0020] Working principle of the utility model: Place the culture dish with the culture medium on the support plate 8 in the storage groove 3. Hold the handle rod 7 and push to rotate the sealing column 42, so that the sealing column 42 and the telescopic rod 44 rotate to the vertical position. Push the sealing column 42 downward to shorten the telescopic rod 44 and move the sealing column 42 into the storage groove 3. At this time, the sealing ring 43 on the side of the sealing column 42 will contact the inner wall of the storage groove 3 to seal the culture dish with the culture medium stored in the sealing groove 3. When the sealing column 42 moves downward, the inclined surfaces on the two clamping blocks 52 will contact the edge position of the storage groove 3. As the sealing column 42 moves downward, the edge position of the storage groove 3 will push the two clamping blocks 52 to move into the two installation grooves 53, causing the two clamping blocks 52 to move into the two installation grooves 53 and compress the two springs 51. When the sealing column 42 moves entirely into the storage groove 3, the elasticity of the spring 51 will push the clamping block 52 to move outward, so that the outer end of the clamping block 52 moves into the clamping groove 54 to fix the sealing column 42. During the downward movement of the sealing column 42, it will push the culture dish and the support plate 8 downward, causing the support plate 8 to compress the support spring 9. When it is necessary to take out the culture dish with the culture medium, two push plates 6 can be pushed towards the middle to drive the two clamping blocks 52 to move into the installation grooves 53. Pull the sealing column 42 upward to move the sealing column 42 to the upper side and push the sealing column 42 to rotate the telescopic rod 44 to the horizontal position. At this time, the elasticity of the support spring 9 will push the support plate 8 and the culture dish upward, moving the culture dish to the opening position of the storage groove 3, enabling people to conveniently take out the culture dish. When the culture medium is stored in a low-temperature environment, the entire base 1 can be placed in the refrigerator. When temporarily used and stored externally, ice cubes can be added to the ice box 2 to cool the base 1 to achieve temporary low-temperature heat preservation externally.
