Description

Technical Field

[0001] This utility model relates to the field of culture rack equipment technology, specifically to a constant temperature culture rack for microorganisms with adjustable layer height. Background Technology

[0002] A microbial culture rack is a device specifically designed for culturing and preserving microbial strains, typically incorporating the functions of a temperature-controlled incubator. This equipment is meticulously designed and manufactured to provide a stable and suitable growth environment for microorganisms, primarily used in medical, pharmaceutical, biological, agricultural, and scientific research fields for storing microbial strains, conducting biological cultures, and performing temperature-controlled experiments at no higher than 65°C. It provides a pollution-free and safe environment suitable for the cultivation and preservation of various microbial strains, including bacteria, molds, and other microorganisms.

[0003] A search revealed an application with application number CN202022230877.3 entitled "A Tissue Culture Rack with Automatic Light Adjustment that Simulates Sunlight Duration and is Convenient to Use," which relates to the field of bioscience. This rack improves the versatility of the equipment, makes the illuminance of the same layer more uniform, has independent real-time control of light adjustment, can more realistically simulate day and night in nature, makes the layer height adjustment of the equipment more convenient, and reduces the limitations of its use.

[0004] The aforementioned utility model only adjusts the spacing between the shelves, but cannot adjust the height of the light lamp. Consequently, it cannot appropriately adjust the spacing between the light lamp and the strain according to the growth stage and needs of the strain, thus affecting the cultivation effect.

[0019] (2) By setting a convex column and a rubber sleeve, after the bearing seat is adjusted, the stepper motor is started to drive the convex column, which causes the rubber sleeve on the surface to fit with the bearing plate, thereby increasing the friction between the bearing seat and the bearing seat, fixing the bearing seat and improving its stability.

[0032] In one embodiment, during use, the inoculum is placed on the support plate 5. Then, by starting the servo motor 10, the second helical gear 9 is driven. With the cooperation of the second helical gear 9 and the first helical gear 8, the lead screw 7 is driven, which drives the support plate 5 to move up and down, thereby adjusting the distance between adjacent support plates 5 to adapt to the culture space of the inoculum. At the same time, by starting the drive motor 23, the bidirectional threaded rod 12 is driven to rotate. Under the action of the guide rod 13, the moving seat 14 is moved axially along the bidirectional threaded rod 12, thereby adjusting the height of the light lamp 16 and adjusting the distance between it and the inoculum to adapt to the growth environment of the inoculum at different stages, improve the efficiency of photosynthesis, and thus promote the growth and development of the inoculum.

[0033] Specifically, a convex column 18 is provided between the base 1 and the top plate 2 and inside the hollow column 3.

[0034] In one embodiment, after the support seat is adjusted, the stepper motor 17 is started to drive the convex column 18, causing the rubber sleeve 19 on the surface to fit into the support plate 5, thereby increasing the friction between the support seat and the support seat, fixing the support seat and improving its stability.

[0035] Specifically, the lower surface of the bearing plate 5 is provided with a grid reinforcing rib 6.

[0042] In one embodiment, controller 24 is used to control the constant temperature culture rack for the microbial culture.

[0043] Working principle: In use, the inoculum is placed on the support plate 5. Then, by starting the servo motor 10, the second helical gear 9 is driven. With the cooperation of the second helical gear 9 and the first helical gear 8, the lead screw 7 is driven, which drives the support plate 5 to move up and down, thereby adjusting the distance between adjacent support plates 5 to adapt to the culture space of the inoculum. At the same time, by starting the drive motor 23, the bidirectional threaded rod 12 is driven to rotate. Under the action of the guide rod 13, the moving seat 14 is moved axially along the bidirectional threaded rod 12, thereby adjusting the height of the light lamp 16 and adjusting the distance between it and the inoculum to adapt to the growth environment of the inoculum at different stages, improve the efficiency of photosynthesis, and thus promote the growth and development of the inoculum. After the support seat is adjusted, by starting the stepper motor 17, the convex column 18 is driven, which causes the rubber sleeve 19 on the surface to fit into the support plate 5, thereby increasing the friction between the support seat and fixing the support seat and improving its stability.
