An ice box 12 is installed on the inner surface of the box 1. A handle 13 is installed on the surface of the lid 11. The low-temperature preservation device is carried by the handle 13 and the movable rod 14. The operator can drag the box 1 by pulling the movable rod 14 and move it by pulling the handle 13. The movable wheel on the box 1 is an existing structure. The ice box 12 provides a low temperature when the bacteria are stored in the box 1 to ensure the temperature of the bacteria during transportation. The box 1 and the lid 11 are made of heat-insulating material to reduce the heat transfer effect between the inside and outside of the device.
[0028] The adjusting mechanism includes a sleeve 2, which is fitted onto the surface of a movable rod 14. A spring plate 21 and a partition plate 22 are movably connected to the inner surface of the movable rod 14. An insert block 23 is fixedly connected to the surface of the partition plate 22. A through hole 24 is opened on the surface of the movable rod 14, and an insertion hole 25 is opened on the surface of the sleeve 2. A threaded cap 26 is abutted onto the surface of the sleeve 2. A connecting band 27 is installed on the surface of the threaded cap 26. A connecting hole 28 is opened on the surface of the connecting band 27. A fixing block 29 is installed on the surface of the connecting hole 28. The two ends of the sleeve 2 are respectively fitted onto two sets of movable rods 14. The two sets of movable rods 14 can be connected after being separated through the sleeve 2, and the inner diameter of the sleeve 2 is the same as the outer diameter of the movable rod 14.
[0029] Furthermore, two sets of sleeves 2 are provided, and the two sets of sleeves 2 are installed on both sides of the movable rod 14. One side of the spring plate 21 is fixedly connected to the inner surface of the movable rod 14, and the other side of the spring plate 21 is fixedly connected to the surface of the partition plate 22. The partition plate 22 is abutted against the inner surface of the movable rod 14. The cross section of the spring plate 21 is "V" shaped. Under the action of the spring plate 21, it can provide support force on the surface of the partition plate 22, and make the partition plate 22 and the insert 23 always tend to move towards the through hole 24. The partition plate 22 can limit the insertion 23 to prevent it from leaving the movable rod 14 under the action of the spring plate 21.
[0030] Furthermore, the insert 23 is inserted into the surfaces of the through hole 24 and the insertion hole 25. The diameter of the through hole 24 and the diameter of the insertion hole 25 are the same. The threaded cap 26 is threadedly connected to the surface of the insert 23. One end of the connecting band 27 is movably connected to the surface of the sleeve 2, and the other end of the connecting band 27 is movably connected to the surface of the threaded cap 26. The threaded cap 26 can be installed through the through hole 24 and the insertion hole 25. The insertion holes 25 are linearly arrayed on the surface of the sleeve 2. The outer diameter of the threaded cap 26 is larger than the diameter of the insertion hole 25. Under the action of the threaded cap 26, the insert 23 inserted into the through hole 24 and the insertion hole 25 can be limited and fixed to prevent the connection from falling off when the movable rod 14 is pulled. The connecting band 27 can keep the threaded cap 26 connected to the sleeve 2 to avoid the situation where it is difficult to find when the threaded cap 26 is removed.
[0031] Furthermore, two sets of connecting holes 28 and fixing blocks 29 are provided. The two sets of connecting holes 28 are opened at both ends of the connecting band 27. One set of fixing blocks 29 is fixedly connected to the surface of the sleeve 2, and the other set of fixing blocks 29 is fixedly connected to the surface of the threaded cap 26. The cross-section of the fixing blocks 29 is "T" shaped. With the connection of the two sets of connecting holes 28 and fixing blocks 29, the connecting band 27 can be installed. The inner diameter of the fixing block 29 is the same as the diameter of the connecting hole 28, while the outer diameter of the fixing block 29 is larger than the diameter of the connecting hole 28. The movement of the connecting band 27 can be limited by the fixing blocks 29.
[0032] Furthermore, the surface of the lid 11 is provided with an abutting mechanism, which includes a pressure plate 3. The pressure plate 3 is movably connected to the surface of the lid 11. A fixed tube 31 is fixedly connected to the surface of the lid 11. A movable tube 32 is fixedly connected to the surface of the pressure plate 3. A connecting block 33 is fixedly connected to the surface of the fixed tube 31. A connecting groove 34 is opened on the surface of the movable tube 32. A support spring 35 is installed on the inner surface of the fixed tube 31 and the movable tube 32. Under the action of the pressure plate 3, it can abut against the surface of the bacteria in the box 1 when the lid 11 is closed, so as to avoid the container containing the bacteria from shaking due to vibration during the operator's carrying process.
[0033] Furthermore, the outer diameter of the fixed tube 31 and the inner diameter of the movable tube 32 are the same. The movable tube 32 is slidably connected to the outer surface of the fixed tube 31. Two sets of connecting blocks 33 and connecting grooves 34 are provided. Two sets of connecting blocks 33 are installed on both sides of the fixed tube 31, and two sets of connecting grooves 34 are opened on both sides of the movable tube 32. The connecting blocks 33 are installed on the surface of the connecting grooves 34. The fixed tube 31 and the movable tube 32 are arranged in a rectangular array on the surface of the box cover 11 and the pressure plate 3, respectively. The connection effect of the fixed tube 31 and the movable tube 32 can be achieved by connecting the connecting blocks 33 and the connecting grooves 34, thereby installing the pressure plate 3 on the surface of the box cover 11. The length of the connecting groove 34 is less than the length of the movable tube 32.
[0034] Furthermore, one end of the support spring 35 is abutted and connected to the surface of the box cover 11, and the other end of the support spring 35 is abutted and connected to the surface of the pressure plate 3. The support spring 35 can apply a supporting force to the surfaces of the box cover 11 and the pressure plate 3, so that the pressure plate 3 can provide a force on the container containing the bacteria when it is squeezed.
[0035] Working principle: Before the operator moves the cryogenic storage device by pulling the movable rod 14, the insert 23 is pressed into the movable rod 14 through the through hole 24 to disconnect it from the insertion hole 25. The partition 22 then disconnects from the movable rod 14, and the spring plate 21 is compressed. The movable rod 14 is then moved and adjusted to its position within the sleeve 2. When the total length of the two sets of movable rods 14 and sleeve 2 meets the requirements and the through hole 24 and the insertion hole 25 are aligned, the insert 23 is inserted into and engaged in the insertion hole 25 under the supporting force applied by the spring plate 21. Then, the threaded cap 26 is threaded onto the surface of the insert 23 and presses against the sleeve 2 when it is rotated and tightened. The connecting band 27 moves at both ends on the sleeve 2 and the threaded cap 26 respectively as the threaded cap 26 moves, thus fulfilling the operator's need to pull the movable rod 14.
[0036] When the inoculum is placed into the box 1 and the box lid 11 is closed, the pressure plate 3 is squeezed by the container containing the inoculum and moves toward the box lid 11, so that the movable tube 32 slides on the surface of the fixed tube 31, while the connecting block 33 slides on the surface of the connecting groove 34. At this time, the support spring 35 is in a compressed state and provides support force on the pressure plate 3, so that the pressure plate 3 always presses against the container when the box lid 11 is closed, so as to limit the position of the inoculum and prevent shaking.
[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
