[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0034] Reference Figure 1-Figure 3The utility model provides an embodiment of a replaceable low-temperature freezing box, comprising an outer shell 1. The outer protective structure of the device is made of plastic material and has strong and durable characteristics to ensure the safety and integrity of the internal components. The outer shell 1 is fixedly connected to a slide rail 2, allowing the inner core compartment 3 to slide smoothly along its length direction, ensuring flexibility and convenience during operation. The inner core compartment 3 is slidably connected to the inner slide rail 2, and a handle 12 is fixedly connected to the inner core compartment 3, which is convenient for the user to easily take out or operate the inner core compartment 3 when needed. A sealing cover 13 is provided on one side of the outer shell 1, and a support block 4 is fixedly connected to the top of one side of the inner core compartment 3 to provide additional support and stability for the inner core compartment 3, so that it is not easy to shake during the sliding process. The support block 4 is rotatably connected to a connecting column 5 inside the inner shell 1, and a fixing bracket 6 is fixedly connected to the inner wall of the outer shell 1 to provide a stable mounting base for the support shaft 7. It is connected to a support shaft 7, and the outer wall of the support shaft 7 is rotatably connected to a buckle 1 8, and the outer wall of the support shaft 7 is rotatably connected to a buckle 2 9, and the buckle 2 9 is slidably connected to the inside of the buckle 1 8 to realize the function of quick locking and releasing. The rotational connection between its outer wall and the support shaft 7 enables it to firmly fix the inner core cabin 3 when locking is required. The outer walls of the buckle 1 8 and the buckle 2 9 are both provided with a connecting component, which is used to drive the buckle 1 8 and the buckle 2 9 to reset. The connecting component includes a connecting plate 10 and a first spring 11. The connecting plate 10 is fixedly connected to the outer walls of the buckle 1 8 and the buckle 2 9 respectively, so that the two can work together effectively. One end of the first spring 11 is fixedly connected to one side of the connecting plate 10, and the other end of the first spring 11 is fixedly connected to one side of the fixing frame 6, ensuring that the first spring 11 can generate a certain elastic force during the release operation, thereby automatically resetting the buckle 1 8 and the buckle 2 9 to the initial state.
[0035] Specifically, when the low-temperature inner core needs to be replaced during the use of the freezing box, the sealing cover 13 is first opened, and the handle 12 is pulled to drive the inner core compartment 3 to slide out from the inside of the outer shell 1. In this process, the inner core is taken out, and then the replaced inner core is placed inside the inner core compartment 3 to ensure that the inner core is in good contact with the inside of the compartment to ensure the freezing effect. Then, the inner core compartment 3 is pushed back into the outer shell 1. During the movement of the inner core compartment 3, the connecting column 5 on one side will contact the buckle 1 8 and the buckle 2 9 inside the outer shell 1. When the connecting column 5 contacts the buckle 1 8, the buckle 1 8 will be forced to rotate outward, and the buckle 2 9 will also rotate accordingly due to the movement of the connecting column 5, so that the connecting column 5 can smoothly slide between the buckle 1 8 and the buckle 2 9. The outer walls of buckle 1 8 and buckle 2 9 are also connected to the connecting plate 10. The connecting plate 10 is squeezed in the process, and pressure is applied to the first spring 11 on one side, causing the first spring 11 to shrink. When the inner core compartment 3 completely slides into the outer shell 1, the first spring 11 will relieve the pressure and rebound quickly, pushing the connecting plate 10 to reset, ensuring the tightness of the entire connection structure. At this time, buckle 1 8 and buckle 2 9 will return to their original position, fixing the connecting column 5 between them, ensuring the stability of the inner core inside the outer shell 1, and effectively preventing accidental displacement caused by vibration or external force, so that the user can easily replace the inner core, ensuring that the freezing box can always maintain a low temperature effect during long-term use, and give full play to the low-temperature preservation function of the freezing box during use.
[0036] Reference Figure 4-Figure 6 , the shell 1 is fixedly connected to a left-right symmetrical support column 15, and the outer wall of each support column 15 is slidably connected to a block 16, which can allow a certain lateral movement under specific operating conditions. The outer wall of each support column 15 is sleeved with a second spring 17, one end of the second spring 17 is fixedly connected to one side of the block 16, and the other end of the second spring 17 is fixedly connected to the inside of the shell 1, so that the second spring 17 can provide a certain buffer and rebound force when the support column 15 is subjected to external pressure or impact. A centrifuge tube rack 14 is provided on the top of the shell 1, and a fixed column 18 is fixedly connected to the inside of the centrifuge tube rack 14, so that the operator can easily adjust it mechanically or manually to control the sliding range of the fixed column 18. The outer wall of the fixed column 18 is slidably connected to a sliding column 20, and the outer wall of the sliding column 20 is fixedly connected to a lever 22. The sliding column 20 not only plays the role of transmitting force, but also provides stability during the movement of the fixed column 18. The outer wall of the fixed column 18 is slidably connected to a tapered column 21, which contacts the sliding column 20.
[0037] Specifically, when centrifuge tubes of different sizes need to be placed, the centrifuge tube rack 14 can be adjusted to accommodate centrifuge tubes of various specifications. First, the user needs to toggle the lever 22, which is connected to the slide post 20. When the lever 22 is toggled, the slide post 20 will slide between the centrifuge tube rack 14 and the housing 1. This sliding is guided by the fixed column 18 inside the slide post 20 to ensure that its movement is smooth and unobstructed. The bottom end of the slide post 20 is connected to a tapered column 21. When the slide post 20 moves downward, the tapered column 21 slides downward accordingly. The shape design has a certain inclination angle, so that during its movement, the tapered column 21 will come into contact with the block 16 inside the shell 1. When subjected to the force of the tapered column 21, it will move sideways. The movement of the block 16 causes the second spring 17 on one side thereof to be compressed, thereby providing the necessary resilience for the block 16. At this time, the movement of the block 16 will release the fixed ball head 19. The ball head 19 is a hemispherical structure responsible for fixing the centrifuge tube rack 14, thereby completing the disassembly of the centrifuge tube rack 14 and facilitating the replacement of centrifuge tube racks 14 with different pore diameters.
[0038] Reference Figure 4-Figure 6 The bottom end of the fixed column 18 is fixedly connected to a ball head 19, and the ball head 19 contacts the block 16. The fixed column 18 and the ball head 19 are both slidably connected inside the shell 1. During operation, the fixed column 18 slides up and down within a certain range. The connection between the fixed column 18 and the ball head 19 enables the fixed column 18 to effectively contact the block 16 when moving, thereby completing the locking of the centrifuge tube rack 14 to meet different experimental requirements.
[0039] Specifically, when installing a new centrifuge tube rack 14, it is only necessary to adjust the internal structure of the centrifuge tube rack 14 until the ball head 19 is realigned with the shell 1. At this time, the ball head 19 is inserted under the block 16 inside the shell 1, and appropriate pressure is applied until the centrifuge tube rack 14 is completely fitted on top of the shell 1. As the installation progresses, the ball head 19 will move under the block 16 and push the block 16 back to its original position through the rebound force of the second spring 17. In this process, the block 16 is fixed above the ball head 19, thereby ensuring the stable installation of the centrifuge tube rack 14 and ensuring that the centrifuge tube rack 14 can be quickly replaced according to the size of different centrifuge tubes during operation, thereby improving the work efficiency and flexibility of the laboratory.
[0040] Working principle: When the low-temperature inner core needs to be replaced during the use of the freezing box, first open the sealing cover 13 and pull the handle 12 to drive the inner core compartment 3 to slide out from the inside of the shell 1. At this time, take out the inner core inside the inner core compartment 3, and put the replacement inner core into the inner core compartment 3. Then push the inner core compartment 3 into the shell 1. During the movement of the inner core compartment 3, the connecting column 5 on one side will contact the buckle 1 8 and buckle 2 9 inside the shell 1, thereby causing the buckle 1 8 and buckle 2 9 to rotate to both sides under force. , so that the connecting column 5 slides between the buckle 1 8 and the buckle 2 9. At the same time, the buckle 1 8 and the buckle 2 9 will respectively drive the connecting plate 10 of the outer wall to move during the rotation. The connecting plate 10 is forced to squeeze the first spring 11 on one side to shrink. When the inner core compartment 3 completely slides into the shell 1, the first spring 11 unloads the force and rebounds, thereby pushing the connecting plate 10 to reset, so that the buckle 1 8 and the buckle 2 9 are rotated back to their original position, buckled on the outer wall of the connecting column 5 to fix it, and ensure the stability of the inner core inside the shell 1. , thereby achieving the effect of facilitating the replacement of the inner core and maintaining a low temperature for a long time. When centrifuge tubes of different sizes need to be placed, the centrifuge tube rack 14 can be replaced according to the size of the centrifuge tube. First, the lever 22 is toggled to force the sliding column 20 to slide inside the centrifuge tube rack 14 and the shell 1. The sliding column 20 pushes the tapered column 21 at the bottom to move when sliding. The tapered column 21 contacts the block 16 inside the shell 1 during the movement, so that the block 16 is forced to move and the second spring 17 on one side thereof is pressed. The centrifuge tube rack 14 is disassembled by squeezing the ball head 19 to shrink it. When installing, the ball head 19 inside the centrifuge tube rack 14 only needs to be reinserted into the shell 1 so that the ball head 19 squeezes the block 16. When the centrifuge tube rack 14 is completely fitted on top of the shell 1, the ball head 19 moves to the bottom of the block 16. The rebound of the second spring 17 drives the block 16 to be stuck on the ball head 19 to fix it, thereby achieving the effect of being able to replace the centrifuge tube rack 14 according to the size of different centrifuge tubes.
