Description

Technical Field

[0001] This utility model relates to the field of cryopreservation rack technology, specifically a cryopreservation rack cold storage auxiliary structure. Background Technology

[0002] Automated stand-alone refrigerators are frequently used in fields such as biomedicine and clinical testing.

[0003] Two cryopreservation rack groups are placed side by side in an ultra-low temperature storage chamber. Each cryopreservation rack group consists of two cryopreservation racks with their bottoms fixed on the same plate. Therefore, a total of four cryopreservation racks are set up in a refrigerator to achieve orderly storage of biological samples in a low temperature environment. The preservation of sample viability requires extremely high temperature stability, and it is necessary to ensure that the cryopreservation rack area is continuously in a uniform ultra-low temperature environment.

[0004] The main problem is that the two freezer shelves located in the middle of the refrigerator have a gap 'a', meaning there's a gap 'a' between the two freezer shelf groups. This gap 'a' causes uneven cooling, which is mainly due to two reasons. First, in the ultra-low temperature storage chamber, because cold air sinks, there's a gradually decreasing temperature gradient from bottom to top throughout the entire storage chamber. This uneven distribution of cooling airflow leads to temperature differences between the freezing positions on different shelves. Second, the distance between the two middle freezer shelves is relatively small, resulting in uneven cooling at the gap between them.

[0005] In summary, in the prior art, the cooling at the gap a between the two freezer racks in the refrigerator is uneven. Utility Model Content

[0006] The purpose of this invention is to provide a cold storage rack auxiliary structure to solve the problems mentioned in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cryogenic storage auxiliary structure for cryopreservation racks, the structure comprising a cryogenic storage component disposed between two cryopreservation rack groups: The cold storage component includes: A support frame is placed between the two cryogenic rack groups; A cold storage ice box is used to independently release cold energy in the gap a between two cryogenic rack groups; There are several placement chambers, distributed on the support frame, and the cold storage ice boxes are installed one by one in the corresponding placement chambers by friction.

[0008] Furthermore, the support frame is provided with several columns of vertical plates and several rows of horizontal plates. The vertical plates divide the support frame into several longitudinal spaces, and the several rows of horizontal plates are laid horizontally in the longitudinal spaces to separate several box-holding chambers.

[0009] Furthermore, the bottom of the cold storage ice box is provided with a groove and an insertion hole, with the groove located at the opening of the insertion hole.

[0010] Furthermore, the horizontal plate is provided with a base, and the base is provided with a rotatably connected plug. The plug hole is inserted into the plug, and there is no relative rotation between the plug hole and the plug, so that the cold storage ice box after insertion is parallel to the box chamber.

[0011] Furthermore, the structure also includes an installation mechanism for adjusting the height of the cross plate on the support frame.

[0012] Furthermore, the installation mechanism includes racks, a set of racks are symmetrically arranged in a longitudinal space, and through holes are symmetrically arranged at both ends of the horizontal plate. A positioning block that moves along the length of the horizontal plate is arranged in the through hole. One end of the positioning block is provided with a positioning tooth; the other end is provided with an inclined surface. The cold storage ice box pushes the positioning tooth to mesh with the corresponding rack through the inclined surface.

[0013] Furthermore, the rotation range of the insertion block is 0-90 degrees.

[0014] Furthermore, when the insert block is parallel to the ground, the inclined surface is located on the side of the positioning block closer to the insert block, and the cold storage ice box is placed from the side of the positioning block closer to the inclined surface.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention includes a support frame placed between two freezer racks, a cold storage ice box for releasing cold energy in the gap 'a' between the two freezer racks, and several placement chambers distributed on the support frame. The cold storage ice boxes are installed one by one into their corresponding placement chambers by friction. This invention releases cold energy separately at the gap 'a' between the two freezer racks, ensuring uniform cooling at that point. Inserting and removing the support frame with the cold storage ice boxes as a whole into and from the refrigerator improves ease of operation and reduces the time required to open the refrigerator's back door. Insert blocks pre-position the cold storage ice boxes through insertion holes, ensuring the ice boxes are always parallel to the placement chambers and that the connection between the ice boxes and the chambers is tight, preventing the ice boxes from falling during handling. The height of the horizontal plate and the height of the placement chambers are adjustable, allowing for the placement of cold storage ice boxes of different sizes, thus expanding the applicability of this device.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] See Figures 1-8 .

[0019] This utility model provides a cold storage auxiliary structure for cryogenic racks, which includes a cold storage component disposed between two cryogenic rack groups 4: The cold storage component includes: Support frame 1 is placed between two cryogenic rack groups 4; The cold storage ice box 2 is used to independently release cold energy in the gap a between the two freezer rack groups 4, so that the cooling at the gap a of the refrigerator is uniform. The box chamber 3 is provided in several parts and distributed on the support frame 1. The cold storage ice boxes 2 are installed one by one in the corresponding box chamber 3 by friction.

[0020] It should be noted that the reference Figure 2 and Figure 8The refrigerator has a front door and a back door, with the back door only opened during installation or maintenance. Several ice storage boxes 2 are directly inserted into gap a. However, because multiple layers and columns of ice storage boxes 2 are needed, they tend to become messy and difficult to place and retrieve. An installation mechanism is used to place and install the ice storage boxes 2 one by one onto the support frame 1. The back door of the refrigerator is opened, and the support frame 1 with the ice storage boxes 2 is inserted into the gap a between the two freezer rack groups 4, completing the installation. The ice storage boxes 2 release cold energy into gap a and the freezer rack groups 4 on both sides, ensuring even cooling at the gaps and heights of the two freezer rack groups 4. The support frame 1 with the ice storage boxes 2 is inserted into and removed from the refrigerator as a whole, improving operational convenience and reducing the time required to open the refrigerator's back door.

[0021] In one embodiment, the support frame 1 is provided with several columns of vertical plates 5 and several rows of horizontal plates 6. The vertical plates 5 divide the support frame 1 into several longitudinal spaces, and the several rows of horizontal plates 6 are arranged horizontally in the longitudinal spaces to separate several box chambers 3.

[0022] This design, for reference Figure 1 The support frame 1 has several columns of vertical plates 5 and several rows of horizontal plates 6, which divide the support frame 1 into several longitudinal spaces. Several rows of horizontal plates 6 are arranged horizontally within these longitudinal spaces, thus dividing the support frame 1 into multiple U-shaped storage chambers 3. During installation, one cold storage ice box 2 corresponds to one storage chamber 3. The cold storage ice box 2 is placed upright on the horizontal plate 6. The cold storage ice box 2 includes a top surface and a bottom surface, as well as two corresponding side surfaces. The bottom surface of the cold storage ice box 2 contacts the horizontal plate 6, the top surface of the cold storage ice box 2 contacts the support frame 1 or another horizontal plate 6, and the two side surfaces of the cold storage ice box 2 contact the vertical plates 5 or the support frame 1. The specific contact surfaces of the remaining three surfaces of the cold storage ice box 2 depend on whether the storage chamber 3 is the outermost or innermost of the several storage chambers 3. Importantly, the four sides of the cold storage ice box 2 are tightly connected after contacting the placement chamber 3. This tight connection means that there is friction between the contact surfaces of the cold storage ice box 2 and the placement chamber 3, and a certain external force is required to move the cold storage ice box 2, thereby fixing the cold storage ice box 2 inside the placement chamber 3.

[0023] In one embodiment, the bottom of the cold storage ice box 2 is provided with a groove 7 and an insertion hole 8, with the groove 7 located at the opening of the insertion hole 8. A base 15 is provided on the horizontal plate 6, and a rotatably connected insertion block 14 is provided on the base 15. The insertion hole 8 is inserted into the insertion block 14, and there is no relative rotation between the insertion hole 8 and the insertion block 14, so that the cold storage ice box 2 is parallel to the placement chamber 3 after insertion. A gap 'a' is left between the top surface of the cold storage ice box 2 and the placement chamber 3 to cooperate with the base 15 and assist the rotation of the insertion block 14.

[0024] This design, for reference Figure 3-5 and Figure 7The bottom of the cold storage ice box 2 has an insertion hole 8. After the cold storage ice box 2 is laid flat, the insertion hole 8 is aligned with the insertion block 14 and inserted. The insertion hole 8 and the insertion block 14 must not rotate relative to each other. Rotating the cold storage ice box 2 upwards by 90 degrees causes the insertion block 14 to rotate synchronously through the insertion hole 8, gradually moving the cold storage ice box 2 into the placement chamber 3. After reaching 90 degrees, the cold storage ice box 2 and the insertion block 14 are in a vertical position, and the cold storage ice box 2 is perfectly installed in the placement chamber 3. The insertion block 14 pre-positions the cold storage ice box 2 through the insertion hole 8, ensuring that the cold storage ice box 2 and the placement chamber 3 are always parallel and that the connection between the cold storage ice box 2 and the placement chamber 3 is tight, preventing the cold storage ice box 2 from falling during handling.

[0025] In one embodiment, the structure further includes an installation mechanism for adjusting the height of the horizontal plate 6 on the support frame 1. The installation mechanism includes racks 9, with a set of racks 9 symmetrically arranged in a longitudinal space. Through holes 10 are symmetrically arranged at both ends of the horizontal plate 6. Positioning blocks 11 that move along the length of the horizontal plate 6 are provided in the through holes 10. One end of the positioning block 11 is provided with positioning teeth 12; the other end is provided with an inclined surface 13. The cold storage ice box 2 pushes the positioning teeth 12 to mesh with the corresponding racks 9 through the inclined surface 13.

[0026] This design, for reference Figure 3 and Figure 7 The installation mechanism includes racks 9, symmetrically arranged in a longitudinal space. When the horizontal plate 6 is moved upwards or downwards, the positioning teeth 12 on the horizontal plate 6 contact the racks 9. Blocked by the racks 9, the positioning teeth 12 drive the positioning block 11 along the through hole 10 towards the center of the horizontal plate 6 until the positioning teeth 12 and racks 9 are no longer engaged, thus moving the horizontal plate 6 to the required height. Once the required height is reached, the cold storage ice box 2 is promptly placed inside. During the process of the cold storage ice box 2 entering the placement chamber 3, when it contacts the inclined surface 13, it pushes the positioning block 11 along the through hole 10, causing the positioning block 11 to drive the positioning teeth 12 to engage with the racks 9 again. When the cold storage ice box 2 has completely entered the placement chamber 3, the positioning teeth 12 are fully engaged with the corresponding racks 9, and the height of the horizontal plate 6 is fixed. The height of the horizontal plate 6 and the height of the placement chamber 3 can be adjusted, allowing for the placement of cold storage ice boxes 2 of different sizes, thus expanding the applicability of this device. Similarly, the cold storage ice box 2 in any of the box chambers 3 within the support frame 1 can be replaced. The difference is that during the replacement process, it is necessary to prevent the high-positioned cold storage ice box 2 from collapsing. The method to prevent this is to use external force to continuously support the horizontal plate 6 located at the top of the box chamber 3.

[0027] In one embodiment, the rotation range of the insert 14 is 0-90 degrees.

[0028] In one embodiment, when the insertion block 14 is parallel to the ground, the inclined surface 13 is located on the side of the positioning block 11 near the insertion block 14, and the cold storage ice box 2 is placed from the side of the positioning block 11 near the inclined surface 13.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0030] It should be noted that if the utility model embodiment involves directional indicators (such as up and down), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0031] Furthermore, the meaning of "and / or" throughout the text includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or a solution that simultaneously satisfies A and B. Additionally, if the utility model embodiments involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" can explicitly or implicitly include at least one of those features. Furthermore, "multiple" refers to two or more.

[0032] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of the utility model.
