Description

Technical Field

[0001] This application relates to the field of biological sample storage technology, specifically to a rapidly assembleable low-temperature biological sample storage box and its assembly method. Background Technology

[0002] Biological samples refer to biological substances obtained from living organisms such as humans, animals, plants, and microorganisms for detection, analysis, or scientific research. They encompass bodily fluids such as blood, urine, and saliva, tissues and organs, cells, and derived molecules such as DNA, RNA, proteins, and metabolites. They are widely used in fields such as clinical diagnosis, disease mechanism research, drug development, forensic identification, and environmental monitoring.

[0003] Traditional biological samples require storage after collection, often requiring a period of time before being placed in a professional freezer. During this time, the biological samples remain exposed to ambient temperatures and may deteriorate if not cooled for an extended period, affecting the accuracy of testing. Therefore, this paper proposes a rapidly assembleable low-temperature storage box for biological samples and its assembly method to address these issues. Summary of the Invention

[0004] The purpose of this application is to provide a rapidly assembled low-temperature storage box for biological samples and an assembly method to solve the problem that biological samples will deteriorate and affect the accuracy of detection if they are not cooled for a long time under the influence of ambient temperature.

[0005] To achieve the above objectives, this application provides the following technical solution: A rapidly assembleable cryogenic storage box for biological samples and its assembly method are disclosed. The box includes an insulated bottom shell, an insulated mounting shell on top of the bottom shell, and an insulated top cover on top of the mounting shell. The bottom shell, mounting shell, and top cover are interconnected by a connecting body. A placement body is installed inside both the bottom shell and the mounting shell. Storage tubes are evenly distributed inside the placement body. Sealing frames are installed at the bottom of the top cover and the bottom of the mounting shell. The top of the bottom shell and the top of the mounting shell are tightly fitted to the sealing frames.

[0006] Preferably, a sponge board is installed inside the heat-insulating top cover, and the bottom of the sponge board is in contact with the sealing frame installed inside the heat-insulating top cover.

[0007] Preferably, the placement body includes a mounting plate, and thermally conductive silicone blocks are installed on both the left and right sides of the mounting plate. A heat-insulating shell is provided on the top of the thermally conductive silicone block, and a heat-conducting plate is fixedly connected to the bottom of the heat-insulating shell. A heat-conducting rod is installed inside the thermally conductive silicone block, and a thermally conductive silicone strip is installed on the outside of the heat-conducting rod. The thermally conductive silicone strip is installed inside the mounting plate.

[0008] Preferably, a heat-conducting strip is installed on the top of the thermally conductive silicone strip, and the top of the heat-conducting strip is fixedly connected to uniformly distributed heat-conducting fins, with the outer side of the heat-conducting fins tightly attached to the thermally conductive silicone strip.

[0009] Preferably, the top of the mounting plate is equipped with uniformly distributed heat-conducting sponge tubes, the storage tube is disposed inside the heat-conducting sponge tubes, and uniformly distributed reinforcing rods are installed inside the heat-conducting sponge tubes. The bottom of the reinforcing rods is fixedly connected to a fixing ring, and the fixing ring is installed inside the mounting plate.

[0010] Preferably, the connecting body includes a fixing block, with mounting rods rotatably connected to both the front and rear sides of the fixing block. A locking block is installed at the bottom of one side of each mounting rod. An mounting block is disposed between the two mounting rods and is positioned directly below the fixing block. The bottom of the mounting block is in close contact with the locking block. A push plate is disposed inside the fixing block. Guide rods, which are fixedly connected to the fixing block, are provided through both the front and rear sides of the push plate. A push spring is disposed on the outer side of the guide rods. A push block is fixedly connected to the bottom of the push plate, and the bottom of the push block is in close contact with the mounting block.

[0011] Preferably, a fixing plate is provided inside the mounting block, and a sliding rod fixedly connected to the mounting block is provided through the fixing plate. A return spring is provided on the outside of the sliding rod. A connecting plate is fixedly connected to one side of the fixing plate, and a positioning block is fixedly connected to the bottom of one side of the connecting plate. A guide plate is fixedly connected to the side of the positioning block away from the connecting plate. The top of the guide plate is arc-shaped, and the side of the locking block away from the mounting rod is arc-shaped.

[0012] Preferably, it includes the following steps: Step 1: Add an appropriate amount of liquid nitrogen into the insulation shell, then cover it with the sealing cap. Place the insulation shell into the mounting plate, where the bottom of the heat-conducting plate is in contact with the heat-conducting silicone block. Then place the preservation tube containing the biological sample into the heat-conducting sponge tube. After placing the preservation tube into the heat-conducting sponge tubes in both the bottom insulation shell and the mounting shell, stack multiple mounting shells on the bottom insulation shell. Finally, place the top insulation cap into the top mounting shell. Step 2: Push the fixing block downwards. The fixing block pushes the push block and the mounting block to fit together, thus limiting the push block. At this time, the fixing block moves downwards outside the push plate and the push block until the locking block moves below the mounting block. Then, under the action of gravity, the mounting rod is set perpendicular to the ground. Then, slowly release the fixing block. At this time, the push spring pushes the fixing block upwards. The fixing block drives the locking block upwards through the mounting rod. The top of the locking block fits tightly with the mounting block, thus positioning the insulation mounting shell. Then, operate multiple different fixing blocks in this way until the insulation top cover is fully limited. At this time, the assembly of the storage box is completed.

[0013] Step 3: When it is necessary to remove the biological sample, push the guide plate and connecting plate upward. The connecting plate pushes the fixing plate upward, and the return spring is compressed. At the same time, the arc-shaped edge of the top of the guide plate pushes the arc-shaped side of the locking block to move. The locking block pushes the mounting rod to rotate inside the fixing block until the plane of the top of the locking block leaves the bottom plane of the mounting block. At this time, the push block pushes the fixing block upward, so that the locking block moves to the front and rear sides of the mounting block. Then, the heat-insulating mounting shell or heat-insulating top cover can be moved upward. After that, the preservation tube containing the biological sample can be removed from the heat-conducting sponge tube.

[0014] Compared with the prior art, the beneficial effects of this application are: 1. In this application, by setting up an insulated bottom shell, an insulated mounting shell, an insulated top cover, a sponge board, a sealing frame, a placement body, a storage tube, and a connecting body, the placement body can install the storage tube containing the biological sample. Then, the insulated bottom shell, the insulated mounting shell, and the insulated top cover insulate and protect the biological sample. At the same time, the placement body cools the air around the storage tube, making the storage of the biological sample in the storage tube more stable. The sealing frame seals the space between the insulated bottom shell, the insulated mounting shell, and the insulated top cover, making the storage box keep warm for a longer time. The sponge board can limit the top of the storage tube, making the installation of the storage tube more stable. 2. In this application, the storage tube is installed through the installation plate, insulation shell, heat-conducting plate, heat-conducting silicone block, heat-conducting rod, heat-conducting sponge tube, reinforcing rod, heat-conducting silicone strip, heat-conducting strip, heat-conducting fins, and fixing ring. The reinforcing rod and fixing ring cooperate to support the heat-conducting sponge tube, making the installation of the storage tube more stable. At the same time, the heat in the storage tube can pass through the heat-conducting sponge tube, and the heat in the storage box enters the heat-conducting rod through the heat-conducting fins, heat-conducting strip, and heat-conducting silicone strip. Then, the heat-conducting rod sends the heat into the insulation shell through the heat-conducting silicone block and heat-conducting plate. The heat is absorbed by the liquid nitrogen in the insulation shell, thereby cooling the storage tube. 3. In this application, by setting a fixed block, push plate, guide rod, push spring, push block, mounting rod, locking block, mounting block, slide rod, return spring, fixed plate, connecting plate, positioning block, and guide plate, the push block can contact the connecting block during installation. At this time, the push spring pushes the fixed block to move upward, so that the top plane of the locking block fits tightly with the bottom of the mounting block, thereby installing the insulation bottom shell, insulation mounting shell, and insulation top cover. The guide plate can push the locking block to move, so that the plane of the locking block leaves the mounting block. At this time, the push spring pushes the insulation mounting shell or insulation top cover upward through the fixed block, releasing the limit. At this time, the storage tube can be easily removed. At the same time, the return spring pushes the fixed plate, connecting plate, positioning block, and guide plate to return to their original positions, facilitating the installation of the insulation bottom shell, insulation mounting shell, and insulation top cover.

[0017] Please see Figure 1-10 This application provides a technical solution: A rapidly assembled low-temperature biological sample storage box and its assembly method are disclosed. The box includes an insulated bottom shell 1, an insulated mounting shell 2 on top of the bottom shell 1, and an insulated top cover 3 on top of the mounting shell 2. The bottom shell 1, mounting shell 2, and top cover 3 are interconnected via a connecting body 8. A placement body 6 is installed inside both the bottom shell 1 and the mounting shell 2, and storage tubes 7 are evenly distributed within the placement body 6. Sealing frames 5 are installed at the bottom of both the top cover 3 and the mounting shell 2. The top of both the bottom shell 1 and the mounting shell 2 are tightly fitted to the sealing frames 5. A sponge board 4 is installed inside the top cover 3, with its bottom fitting tightly to the sealing frames 5. The sealing frames 5 seal the bottom shell 1, mounting shell 2, and top cover 3, extending the storage box's insulation time. The sponge board 4 also limits the position of the top of the storage tubes 7, making their installation more stable.

[0018] like Figures 1 to 6As shown, the main body 6 includes a mounting plate 601. Thermally conductive silicone blocks 604 are installed on both the left and right sides of the mounting plate 601. An insulation shell 602 is provided on the top of each thermally conductive silicone block 604. A heat-conducting plate 603 is fixedly connected to the bottom of the insulation shell 602. A heat-conducting rod 605 is installed inside each thermally conductive silicone block 604. A thermally conductive silicone strip 608 is installed on the outside of the heat-conducting rod 605. The thermally conductive silicone strip 608 is installed inside the mounting plate 601. A heat-conducting strip 609 is installed on the top of the thermally conductive silicone strip 608. The top of 609 is fixedly connected to uniformly distributed heat-conducting fins 610. The outer side of the heat-conducting fins 610 is tightly attached to the heat-conducting silicone strip 608. An appropriate amount of liquid nitrogen is added into the insulation shell 602, and then the sealing cap of the insulation shell 602 is closed. The insulation shell 602 is then placed inside the mounting plate 601. At this time, the bottom of the heat-conducting plate 603 is in contact with the heat-conducting silicone block 604. Then, the preservation tube 7 containing the biological sample is placed inside the heat-conducting sponge tube 606. The insulation bottom shell 1 and the insulation mounting shell 2 are in the same position. After the heat-conducting sponge tubes 606 are all placed in the storage tubes 7, multiple heat-insulating mounting shells 2 are stacked on the heat-insulating bottom shell 1. Finally, the heat-insulating top cover 3 is placed inside the top heat-insulating mounting shell 2. After the heat-insulating mounting shells 2 and the heat-insulating top cover 3 are installed, the heat inside the heat-insulating bottom shell 1, heat-insulating mounting shells 2 and heat-insulating top cover 3 is transferred to the heat-conducting silicone strip 608 through the heat-conducting fins 610 and heat-conducting strips 609. Then, the heat enters the heat-conducting plate 603 through the heat-conducting rods 605 and heat-conducting silicone blocks 604. Finally, the heat enters the liquid nitrogen inside the insulation shell 602, where the liquid nitrogen absorbs the heat, keeping the biological sample in a low-temperature environment to prevent it from deteriorating. The top of the mounting plate 601 is equipped with uniformly distributed heat-conducting sponge tubes 606, and the storage tube 7 is placed inside the heat-conducting sponge tubes 606. The heat-conducting sponge tubes 606 are equipped with uniformly distributed reinforcing rods 607, and the bottom of the reinforcing rods 607 is fixedly connected to a fixing ring 611, which is installed inside the mounting plate 601.

[0019] like Figures 7 to 10As shown, the connecting body 8 includes a fixing block 801. Mounting rods 806 are rotatably connected to both the front and rear sides of the fixing block 801. A locking block 807 is installed at the bottom of one side of each mounting rod 806. An mounting block 808 is positioned between the two mounting rods 806, directly below the fixing block 801. The bottom of the mounting block 808 is in contact with the locking block 807. A push plate 802 is installed inside the fixing block 801. Guide rods 803, which are fixedly connected to the fixing block 801, are threaded through both the front and rear sides of the push plate 802. A push spring 804 is installed on the outer side of the guide rods 803. A push block 805 is fixedly connected to the bottom of the push plate 802, and the bottom of the push block 805 is tightly fitted to the mounting block 808. The mounting block 808 has a fixing plate 811 inside, and a slide rod 809 is fixedly connected to the mounting block 808 through the fixing plate 811. A return spring 810 is provided on the outside of the slide rod 809. A connecting plate 812 is fixedly connected to one side of the fixing plate 811, and a positioning block 813 is fixedly connected to the bottom of one side of the connecting plate 812. A guide plate 814 is fixedly connected to the side of the positioning block 813 away from the connecting plate 812. The top of the guide plate 814 is arc-shaped. The side of the locking block 807 away from the mounting rod 806 is also arc-shaped. Pushing the fixing block 801 downwards causes the fixing block 801 to push the push block 805 to fit against the mounting block 808, thereby engaging the push block 805. The device is positioned such that the fixing block 801 moves downwards outside the push plate 802 and push block 805 until the locking block 807 moves below the mounting block 808. Then, under the influence of gravity, the mounting rod 806 is set perpendicular to the ground. The fixing block 801 is then slowly released, at which point the push spring 804 pushes the fixing block 801 upwards. The fixing block 801, through the mounting rod 806, drives the locking block 807 upwards, and the top of the locking block 807 fits tightly against the mounting block 808, thus positioning the thermal insulation mounting shell 2. This process is repeated with multiple different fixing blocks 801 until the thermal insulation top cover 3 is fully positioned. At this point, the assembly of the storage box is complete, ready for use when biological samples need to be retrieved. When the sample is removed, push the guide plate 814 and the connecting plate 812 upward. The connecting plate 812 pushes the fixing plate 811 upward. The return spring 810 is compressed by force. At the same time, the top arc edge of the guide plate 814 pushes the arc side of the locking block 807 to move. The locking block 807 pushes the mounting rod 806 to rotate inside the fixing block 801 until the top plane of the locking block 807 leaves the bottom plane of the mounting block 808. At this time, the push block 805 pushes the fixing block 801 upward, so that the locking block 807 moves to the front and rear sides of the mounting block 808. Then the heat-insulating mounting shell 2 or the heat-insulating top cover 3 can be moved upward. After that, the preservation tube 7 containing the biological sample can be taken out from the heat-conducting sponge tube 606.
