Biological enzymes are non-toxic, environmentally friendly biocatalysts, and their chemical nature is protein. The production and application of enzymes have a history of more than 80 years at home and abroad. In the 1980s, bioengineering as an emerging high-tech technology has developed rapidly in my country, and its manufacturing and application fields have gradually expanded. When preparing biological enzymes, the biological enzyme reagent samples need to be stored in refrigeration equipment.

[0003] As the Chinese patent with application number CN202122254511.4, a freezing device suitable for storing protease sample EP tubes is disclosed, which includes a device body and a box cover detachably mounted on the top of the device body, and also includes: a top plate fixedly mounted in the top of the device body, a circular hole is evenly connected on the top plate, and four groups of limit assemblies are evenly arranged in the circular hole, a bottom plate arranged in the lower part of the device body, a circular cone groove is evenly arranged on the bottom plate, a support assembly symmetrically arranged in the bottom end of the device body, and a driving assembly fixedly mounted in the middle of the bottom end of the device body. The freezing device can adjust the spacing between the top plate and the bottom plate according to EP tubes of different lengths, and can limit EP tubes of different lengths. Because the protease sample EP tubes are stored and assembled on the bottom plate, when the box cover is opened and a single group of protease sample EP tubes are taken out, other groups of EP tubes will be exposed to the outside. When the outdoor temperature is very high, the protease samples in the EP tubes are easily damaged during multiple pick-ups and drops, affecting the experimental effect. Utility Model Content

[0026] A fixed shelf 10 is provided above each movable shelf 5, and both ends of the fixed shelf 10 are fixedly connected to the wall of the refrigerating chamber 4. A plurality of storage boxes 7 are placed between the movable shelf 5 and the fixed shelf 10, and the upper end of the storage box 7 is slidably connected to the second limiter provided at the lower end of the fixed shelf 10, and the lower end of the storage box 7 is slidably connected to the third limiter provided at the upper end of the movable shelf 5. A baffle 13 is provided on the back of the movable shelf 5, and the baffle 13 is in contact with the back of the movable shelf 5. The storage box 7 stored between the movable shelf 5 and the fixed shelf 10 can slide horizontally between the movable shelf 5 and the fixed shelf 10. When the door 2 is opened, the operator can pull the storage box 7 placed between the movable shelf 5 and the fixed shelf 10 out of the refrigerating chamber 4 from outside the refrigerating chamber 1.

[0027] A storage box 7 has multiple slots 14, and multiple groups of enzyme samples are stored separately through multiple storage boxes 7. Since each storage box 7 is an independent structure, when taking out a single group of samples from the cold storage chamber 4, it is only necessary to pull the corresponding storage box 7 out from between the movable shelf 5 and the fixed shelf 10, and the other storage boxes 7 will still stay between the movable shelf 5 and the fixed shelf 10, and will not interfere with other enzyme samples. In addition, when the movable shelf 5 is pulled, the movable shelf 5 can pull out all the storage boxes 7 placed between the movable shelf 5 and the fixed shelf 10 through the baffle 13 on the back thereof, thereby improving the efficiency of taking and placing the enzymes.

[0028] More specifically, each storage box 7 is arranged in a row on the movable frame plate 5 and the fixed frame plate 10, and two adjacent storage boxes 7 are in contact with each other. A plurality of slots 14 for storing bio-enzyme reagent tubes are provided at the upper end of the storage box 7. The two sides of the storage box 7 are hollowed out, and the slots 14 are connected to the refrigeration chamber 4 through the hollow structures on both sides of the storage box 7. The cold air in the refrigeration chamber 4 can pass through the storage box 7 to keep the bio-enzyme reagent tubes stored in the slots 14 in a freeze-dried state. When taking out the reagent tube, just pull the corresponding storage box 7 out of the refrigeration chamber 4.

When the movable shelf 5 is pulled, the third guide edge 17 on the wall of the refrigerating chamber 4 can guide and support the movable shelf 5 from both sides of the movable shelf 5, so that the movable shelf 5 can maintain a horizontal sliding state when being pulled out of the refrigerating chamber 4.

[0031] The second stopper includes a first slide groove 15 provided at the upper end of the storage box 7, the two ends of the first slide groove 15 extend to the front and back of the storage box 7, the first slide groove 15 is slidably connected to the second guide edge 11 provided at the lower end of the fixed frame plate 10, and the upper end of the first slide groove 15 is fixedly connected to the fixed frame plate 10. The lower end of the fixed frame plate 10 has a plurality of second guide edges 11, each of which corresponds to a storage box 7. When the storage box 7 is pulled out from between the fixed frame plate 10 and the movable frame plate 5, the second guide edges 11 will guide the storage box 7 from the upper end of the storage box 7.

[0032] The third stopper includes a second slide groove 16 provided at the lower end of the storage box 7, the two ends of the second slide groove 16 extend to the front and back of the storage box 7, the second slide groove 16 is slidably connected to the first guide edge 9 provided at the upper end of the movable frame plate 5, and the lower end of the first guide edge 9 is fixedly connected to the movable frame plate 5. The upper end of the movable frame plate 5 also has a plurality of first guide edges 9, each of which corresponds to a storage box 7.

Multiple groups of biological enzyme samples are stored separately through multiple storage boxes 7. Since each storage box 7 is an independent structure, when a single group of samples is taken out from the cold storage chamber 4, it is only necessary to pull the corresponding storage box 7 out from between the movable shelf 5 and the fixed shelf 10, and the other storage boxes 7 will still stay between the movable shelf 5 and the fixed shelf 10, and will not interfere with other biological enzyme samples. In addition, when the movable shelf 5 is pulled, the movable shelf 5 can pull out all the storage boxes 7 between the movable shelf 5 and the fixed shelf 10 through the baffle 13 on the back thereof, thereby improving the efficiency of taking and placing the biological enzymes.
