Description

Technical Field

[0001] This utility model relates to the field of cryopreservation rack technology, specifically to a double U-shaped cryopreservation rack structure. Background Technology

[0002] In the fields of biomedicine and life sciences, long-term cryopreservation of biological samples is crucial. As a core storage device, the design of the internal cryopreservation racks of automated single-unit refrigerators directly affects the sample storage capacity, efficiency, and safety.

[0003] Most existing automated single-unit refrigerators use shelf-type or traditional frame-type cryopreservation racks, with one cryopreservation rack on each side and two connected together in the middle. The internal cold atmosphere of the connected rack is not good, and the cryopreservation racks will deform to varying degrees after being in an ultra-low temperature environment for a long time. In the field of fully automated ultra-low temperature refrigerators, the deformation of the cryopreservation racks will greatly reduce the accuracy of storage and retrieval, and it is easy to cause the cryopreservation boxes to fail to be accurately stored in the cryopreservation positions of the cryopreservation racks. In cases of severe deformation of the cryopreservation racks, it may even cause the cryopreservation boxes to fall off during storage, resulting in the loss of biological samples.

[0004] Therefore, considering the need to improve the stability of the cryopreservation rack, and the fact that the automated single-unit refrigerator has a three-dimensional moving robotic arm structure above it for picking up and placing cryopreservation boxes, it is also necessary to consider avoiding obstructing the robotic arm's function of picking up and placing cryopreservation boxes; in view of this, we propose a double U-shaped cryopreservation rack structure. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings mentioned in the background art and provide a double U-shaped cryopreservation rack structure.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A double U-shaped cryogenic rack structure includes two cryogenic components installed symmetrically in the cryogenic cavity of an automated single-unit refrigerator body; The cryopreservation assembly includes two symmetrically arranged cryopreservation racks, and a bottom connecting plate or connecting rod is detachably installed between the two cryopreservation racks.

[0007] Preferably, the cryopreservation rack includes multiple horizontal racks and multiple vertical racks that are perpendicularly installed on the inside of the back panel; A storage cavity is provided between the horizontal frame and the vertical frame.

[0008] Preferably, the inner side of the vertical frame is provided with a plurality of evenly distributed side supports for supporting the cryopreservation boxes.

[0009] Preferably, the bottom end of the vertical frame is provided with a first protrusion; The bottom connecting plate includes a base plate on which card plates are symmetrically installed, and the card plates are provided with a second card slot for mounting the first protrusion.

[0010] Preferably, the connecting rod is fixedly connected between the bottom crossbars of the two cryopreservation racks.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This double-U-shaped cryopreservation rack structure achieves a double-U-shaped design for the cryopreservation rack, leaving a gap in the middle of the rack, which is conducive to obtaining a more uniform internal cold atmosphere. In addition, the double-U-shaped structure provides more reliable structural stability than a single rack, does not hinder the existing robotic arm's function of picking up and placing cryopreservation boxes, and helps to avoid deformation in the ultra-low temperature storage environment, thereby ensuring the accuracy of the cryopreservation box sample picking process.

[0014] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] Please see Figures 1-5 The present invention will describe the above technical solution in detail through the following embodiments: Example 1 The double U-shaped cryogenic rack structure in this embodiment includes two cryogenic components 2 installed in the cryogenic cavity 101 of the automated single-unit refrigerator body 1 and arranged symmetrically. The automated single-unit refrigerator body 1 is equipped with a door 11, and a partition foam board 3 is provided above the cryogenic components 2 for heat preservation and cold storage.

[0016] Specifically, in this embodiment, as follows: Figure 1 , Figure 2 As shown, the two cryogenic components 2 form a U-shaped structure, which is different from the existing structure in which the two cryogenic racks in the middle are connected together and the two sides are set independently. The double U-shaped structure design makes the middle unconnected, which can obtain a more uniform internal cold atmosphere and achieve an overall stable structure with the cryogenic racks on both sides connected.

[0017] This implementation example Figure 3 , Figure 4 As shown in the structure, the cryopreservation assembly 2 includes two symmetrically arranged cryopreservation racks 21, and a bottom connecting plate 22 is detachably installed between the two cryopreservation racks 21; the cryopreservation rack 21 includes four horizontal racks 211 and seven vertical racks 212 that are perpendicularly installed on the inner side of the back plate 213, and a storage cavity 201 is provided between adjacent horizontal racks 211 and vertical racks 212. In this embodiment, evenly distributed side support plates 2122 are provided on the inner side of the vertical racks 212 to support the cryopreservation box.

[0018] like Figure 4 As shown, in order to facilitate disassembly and assembly, this embodiment provides a first protrusion 2121 at the bottom of the vertical frame 212, and the bottom connecting plate 22 includes a base plate 221 on which a card plate 222 is symmetrically installed. A second card slot 2222 is provided on the card plate 222 for carding the first protrusion 2121 to complete the fixation.

[0019] Example 2 In this embodiment, a connecting rod 23 is welded between the bottommost crossbeams 211 to form a fixed U-shaped structure between the two cryopreservation racks 21, which improves stability. In other embodiments, multiple connecting rods 23 can be fixedly installed between the bottommost two crossbeams 211.

[0020] The working principle of the double U-shaped cryopreservation rack structure of this application is as follows: the two cryopreservation racks 21 on both sides are connected by the bottom connecting plate 22 or the connecting rod 23 to form a U-shaped structure that does not hinder the placement of cryopreservation tubes by the robotic arm. Compared with a single rack, it can achieve a stable effect and is easy to disassemble and assemble, which helps to improve the accuracy of the cryopreservation box placement process.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0022] 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 exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
