Technical Field
[0001] This utility model relates to the field of experimental instrument technology, specifically a liquid nitrogen insulated container device with detachable centrifuge tubes. Background Technology
[0002] Nitrogen is a colorless, odorless, and tasteless gas under normal conditions, and is generally non-toxic. Nitrogen accounts for 78.12% (volume fraction) of the total atmosphere, and its gas density under standard conditions is 1.25 g·dm⁻³. When nitrogen is cooled to -195.8℃ under standard atmospheric pressure, it becomes a colorless liquid, i.e., liquid nitrogen, which is often used as a quick-freezing agent during sampling.
[0003] The existing liquid nitrogen insulation tank requires manual control to keep the centrifuge tubes stable during use, which makes the device inconvenient to use. After use, the liquid nitrogen insulation tank needs to be cleaned, but the inside of the original liquid nitrogen insulation tank cannot be quickly disassembled, making subsequent cleaning of the liquid nitrogen insulation tank inconvenient and affecting the next use.
[0004] Therefore, those skilled in the art have provided a liquid nitrogen insulated container device with detachable centrifuge tubes to solve the problems mentioned in the background art. Utility Model Content

[0033] Example 2:
[0034] Please see Figure 1-4 This embodiment provides a technical solution based on Embodiment 1:
[0035] The insulated bucket body 1 has an iron column 6 fixedly installed inside it. The iron column 6 has a first slot 7 at its upper end and a second slot 8 on both sides of the first slot 7.
[0036] The inner cavity 2 is located inside the body 1 of the heat preservation bucket. A sealing cover 3 is installed at the upper end of the body 1 of the heat preservation bucket, and a rotating plate 4 is fixedly installed at the lower end of the sealing cover 3. A handle 5 is fixedly installed at the upper end of the sealing cover 3.
[0037] The iron column 6 is cylindrical in shape. The first slot 7 is symmetrically installed on the front and back sides of the iron column 6 with the iron column 6 as the center reference. The second slot 8 is symmetrically installed on the left and right sides of the iron column 6 with the iron column 6 as the center reference. The internal structure of the first slot 7 and the second slot 8 is the same, and the height of the first slot 7 is higher than the height of the second slot 8.
[0038] The inner cavity 2 is a hollow structure, and the inner wall of the heat preservation bucket body 1 is divided into a double-layer structure. The upper end of the handle 5 is equipped with anti-slip texture.
[0039] In this embodiment, the insulated container body 1 is used to store liquid nitrogen. Its inner cavity 2 is designed with a double-layer inner wall structure, which can effectively buffer external vibration or impact force and ensure internal stability. The sealing cover 3 is connected to the upper end of the insulated container body 1 by a rotating plate 4 to achieve a tight seal. The upper end of the sealing cover 3 is fixed with a handle 5, which is convenient for users to hold and rotate to open and close the sealing cover 3. The upper end of the cylindrical iron column 6 has two slots (first slot 7 and second slot 8). Through the engagement of the slots with the corresponding blocks (first block 10 and second block 16), different sizes of buckles (bucket one 12 and buckle two 18) can be installed to adapt to centrifuge tubes of different specifications.
[0040] The working principle of this utility model is as follows: Circular buckles of different sizes (buckle one 12, buckle two 18) are installed in a 360° staggered arrangement on a cylindrical iron column 6. Two buckles of the same size are positioned vertically at the same location. Buckle one 12 is fixed to connecting ring one 9 via mounting rod one 11, and a support ring 13 and a silicone anti-slip pad 14 are installed inside. Buckle two 18 is fixed via connecting ring two 15. First, a centrifuge tube is placed into buckle two 18 to ensure stability and prevent shaking. Then, the centrifuge tube is inserted into buckle one 12 and secured by the support ring 13 and the silicone anti-slip pad 14. Liquid ammonia is initially injected into the insulation tank body 1, and the liquid nitrogen level must be lower than the level inside buckle two 18. To ensure the centrifuge tubes are not affected by external forces, secure the other centrifuge tubes to clip 12, and continue to add liquid nitrogen to the required height. Tightly seal the sealing cap 3 onto the upper end of the insulated container body 1 to complete the experimental preparation. Open the sealing cap 3 using handle 5, and remove the centrifuge tubes from clip 12 and clip 28 in sequence. Pull the connecting ring 9 upwards to disengage the first locking block 10 from the first locking groove 7 of the iron pillar 6. Remove the clip 12 assembly. Pull the connecting ring 25 in the same way to disengage the second locking block 16 from the second locking groove 8. Remove the clip 28 assembly. After separating all detachable structures (clips, connecting rings, etc.) inside the insulated container body 1, perform a thorough cleaning.
