Description

Technical Field

[0001] This utility model relates to the field of biomedical engineering and laboratory equipment technology, and in particular to a cell storage rack. Background Technology

[0002] Cell storage racks, also known as multi-layer cold storage racks for cell storage, are used to safely and efficiently store biological samples, such as cells, tissues, and other temperature-sensitive biological materials, in a controlled low-temperature environment. These cold storage racks typically have a multi-layer structure, with each layer capable of holding multiple storage containers or drawers, thus greatly increasing the storage capacity per unit area. They provide optimized space utilization solutions for laboratories, hospitals, and research institutions, and ensure that cell samples maintain their integrity and viability throughout the storage period.

[0003] However, existing single-sided multi-layer refrigerated racks usually occupy a large amount of space after installation due to the large number of containers. While double-sided multi-layer refrigerated racks can save space to some extent, the racks are set up on both sides, requiring people to walk around the racks to retrieve materials, which is inconvenient and can affect the efficiency of picking up goods to some extent. Utility Model Content

[0004] The main purpose of this invention is to provide a cell storage rack that increases the storage space for glass tubes containing cell fluid, and makes it easier for users to access and store them, thereby improving efficiency.

[0005] To achieve the above objectives, this utility model proposes a cell storage rack, comprising:

[0006] A refrigerator, wherein a number of shelves are rotatably connected inside the refrigerator, and a number of storage boxes are slidably connected to both sides of each shelf, and each shelf is equidistantly arranged along the height side of the shelf;

[0007] Several sealed doors, the number of which is the same as the number of shelves, each sealed door is hinged to the opening of the refrigerator, and several material access windows are hinged to the opening of the refrigerator for taking out the storage box;

[0008] An adjustment component, located on the lower side of the refrigerator, is used to adjust the flipping of each shelf.

[0009] In one possible implementation, the regulating component includes:

[0010] A number of foot pedals are provided, each of which is hinged to the lower side of the sealed door. The number of foot pedals is the same as the number of sealed doors. Each foot pedal is hinged to the lower side of the refrigerator. Each foot pedal is provided with an elastic element between itself and the lower side of the refrigerator.

[0011] Several transmission plates, each transmission plate is hinged to the bottom wall of the refrigerator, one end of each transmission plate is slidably hinged to the lower side of the adjacent foot pedal, and a linkage plate is hinged to the end of each transmission plate away from the foot pedal. Each linkage plate is slidably connected to the inner wall of the refrigerator.

[0012] The drive assembly is used in conjunction with the linkage plate to control the flipping of the adjacent shelf.

[0013] In one possible implementation, the driving component includes:

[0014] Two limiting seats are fixedly connected to the inner walls of the refrigerator on both sides. Each limiting seat is rotatably connected to a first gear. Each limiting seat is fixedly connected to a limiting post. Each limiting post is slidably connected to a positioning seat. Each positioning seat is slidably connected to the bottom wall of the refrigerator. Each limiting post is fitted with a limiting spring.

[0015] Two second gears, each of which is rotatably connected to a positioning seat;

[0016] A toothed belt, which is fitted around the outer rings of two first gears and two second gears for transmission;

[0017] A drive motor is fixedly connected to the inner wall of the refrigerator, and the drive of the drive motor is connected to one of the first gears.

[0018] Several linkage gears, each of which is fixedly connected to the underside of each shelf.

[0019] In one possible implementation, the linkage plate is connected to a tension cylinder on the side facing the toothed belt.

[0020] In one possible implementation, each of the linkage gears is engaged with a drive gear on the side facing the linkage plate.

[0021] In one possible implementation, each of the pedals is fixedly connected with an anti-slip pad.

[0022] This utility model's technical solution, through the combination of several sealed doors and several material access windows, employs multi-layered temperature insulation measures to ensure a more stable temperature within the refrigerator. This, in turn, allows for more stable cell storage. Furthermore, the multiple material access windows minimize the impact on other units when users store or retrieve glass tubes containing cell fluid at a single height, guaranteeing the overall cell storage effect within the refrigerator. In addition, the adjustable components allow for precise control of the shelf rotation, enabling users to access the shelves from one side. This maximizes the use of interior space, increases storage capacity for glass tubes containing cell fluid, and facilitates user access and storage, improving efficiency. Multiple configurations are available to adapt to different refrigerator sizes, enhancing user convenience. These different configurations reduce the procurement cost of drive components, significantly lowering manufacturing and operating costs. The elimination of additional electronic control modules simplifies equipment maintenance, reducing the need for tedious debugging and minimizing the workload of maintenance personnel.

[0031] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0032] This invention proposes a cell storage rack.

[0033] Reference Figures 1 to 4 ,include:

[0034] The refrigerator 11 has several shelves 12 rotatably connected inside it. Several storage boxes 13 are slidably connected to both sides of each shelf 12. Each shelf 12 is equidistantly arranged along the height side of the shelf 12.

[0035] Several sealed doors 14, the number of which is the same as the number of shelves 12, each sealed door 14 is hinged to the opening of the refrigerator 11, and several material retrieval windows 15 are hinged to the opening of the refrigerator 11 for retrieving the storage box 13.

[0036] An adjustment component is located on the lower side of the refrigerator 11 and is used to adjust the flipping of each shelf 12;

[0037] Through the combination of several sealed doors 14 and several access windows 15, and multiple layers of temperature insulation measures, the temperature inside the refrigerator 11 is made more stable, thus ensuring greater stability of the cells stored in the refrigerator 11. Furthermore, the multiple access windows 15 minimize the impact on other units when users store or retrieve glass tubes containing cell fluid at a single height, guaranteeing the overall cell storage effect within the refrigerator 11. In addition, with the adjustment components, the rotation of the shelf 12 can be precisely controlled, allowing users to access the storage boxes 13 on the shelf 12 from one side. This makes better use of the interior space of the refrigerator 11, increasing the storage space for glass tubes containing cell fluid and facilitating user access and storage, thus improving efficiency. Multiple configurations are available to suit the size of the refrigerator 11, enhancing user convenience. Different configurations reduce the procurement cost of drive components, significantly lowering equipment manufacturing and operating costs. The elimination of additional electronic control modules simplifies equipment maintenance, reducing the need for tedious debugging and minimizing the workload of maintenance personnel.

[0038] It is worth mentioning that the refrigerator 11 is equipped with several sealing gaskets to block the gaps inside the refrigerator 11 and ensure that the temperature inside the refrigerator 11 is stable.

[0039] Reference Figures 1 to 4 The adjustment components include:

[0040] Several foot pedals 21 are hinged to the lower side of the sealing door 14. The number of foot pedals 21 is the same as the number of sealing doors 14. Each foot pedal 21 is hinged to the lower side of the refrigerator 11. Each foot pedal 21 is provided with an elastic element between itself and the lower side of the refrigerator 11.

[0041] Several transmission plates 22 are hinged to the bottom wall of the refrigerator 11. One end of each transmission plate 22 is slidably hinged to the lower side of the adjacent foot pedal 21. A linkage plate 23 is hinged to the end of each transmission plate 22 away from the foot pedal 21. Each linkage plate 23 is slidably connected to the inner wall of the refrigerator 11.

[0042] A drive assembly is used in conjunction with the linkage plate 23 to control the flipping of the adjacent shelf 12;

[0043] By pressing the pedal 21 in the adjustment assembly, the pedal 21 rotates downward around the point hinged to the lower side of the refrigerator 11, thereby driving the end of the transmission plate 22 away from the pedal 21 to rise upward around the point hinged to the lower side of the refrigerator 11. This causes the linkage plate 23 to move along the inner wall of the refrigerator 11 towards the drive assembly, thus rotating the shelf 12 corresponding to the pedal 21. The drive assembly, through the transmission of the toothed belt 37 by a single drive motor 38 and with the cooperation of the pedal 21, can precisely rotate the shelf 12 in front of the pedal 21, causing the storage box 13 on the other side of the shelf 12 to flip to the front, making it convenient for users to store or retrieve glass tubes containing cells, improving user convenience. In addition, it reduces the procurement cost of the drive components, greatly reducing the manufacturing and operating costs of the equipment. It eliminates the need for additional electronic control modules, making equipment maintenance easier and reducing the workload of maintenance personnel by eliminating tedious debugging. It is worth mentioning that the above-mentioned... When the refrigerator 11 is large and can accommodate more shelves 12, or when the refrigerator 11 is small and can only hold two shelves 12 or less, the drive component is preferably a servo motor. The servo motor is directly connected to the shelf 12. The linkage plate 23 moves towards the servo motor, thereby energizing it. Then, the rotation of the shelf 12 is precisely controlled by the control button on the outside of the refrigerator 11. The rotation of the shelf 12 is only triggered when the user steps on the foot pedal 21. When the foot pedal 21 is no longer under pressure, the elastic element under the foot pedal 21 will cause the foot pedal 21 to rebound. During this process, the linkage plate 23 will also reset, so the user cannot control the rotation of the shelf 12. This process can effectively limit the user's operation rights and prevent the storage box 13 that is being stored or retrieved from interfering with the inner wall of the refrigerator 11 due to accidental touch, ensuring the stable operation of the equipment and the safety of the staff.

[0044] Reference Figures 2 to 4 The driving components include:

[0045] Two limiting seats 31 are fixedly connected to the inner walls of the refrigerator 11 on both sides. Each limiting seat 31 is rotatably connected to a first gear 32. Each limiting seat 31 is fixedly connected to a limiting post 33. Each limiting post 33 is slidably connected to a positioning seat 34. Each positioning seat 34 is slidably connected to the bottom wall of the refrigerator 11. Each limiting post 33 is fitted with a limiting spring 35.

[0046] Two second gears 36 are rotatably connected to each positioning seat 34;

[0047] A toothed belt 37 is fitted around the outer rings of two first gears 32 and two second gears 36 for transmission.

[0048] The drive motor 38 is fixedly connected to the inner wall of the refrigerator 11, and the drive of the drive motor 38 is connected to one of the first gears 32.

[0049] Several linkage gears 39 are fixedly connected to the lower side of each shelf 12;

[0050] The drive assembly enables the user to drive the motor 38, which in turn drives the toothed belt 37, which surrounds several linkage gears 39, to move or stop stably along the first gear 32 and the second gear 36. When the user presses the pedal 21 to deform the toothed belt 37 towards the linkage gears 39, the deformed area of ​​the toothed belt 37 engages with the linkage gears 39. As the toothed belt 37 moves, it drives the linkage gears 39 to rotate, thereby causing the shelf 12 fixed to the linkage gears 39 to rotate. The advantage of this drive assembly is that it can be used when the refrigerator 11 is large and can hold a sufficient number of items. When the shelf 12 is in use, the toothed belt 37 is driven by a single drive motor 38, and with the cooperation of the foot pedal 21, the shelf 12 in front of the foot pedal 21 can be rotated precisely. This causes the storage box 13 on the other side of the shelf 12 to flip to the front, making it convenient for users to store or retrieve the glass tubes containing cells. This improves user convenience and reduces the procurement cost of drive components, greatly reducing the manufacturing and operating costs of the equipment. No additional electronic control module is required, making equipment maintenance easier and eliminating the need for tedious debugging, thus reducing the workload of maintenance personnel.

[0051] Reference Figures 3 to 4 The tension cylinder 41 is connected to the side of the linkage plate 23 facing the toothed belt 37;

[0052] The linkage plate 23 moves towards the toothed belt 37 through the linkage transmission with the pedal 21, thereby bending and deforming the toothed belt 37. Finally, the bent and deformed tooth surface of the toothed belt 37 meshes with the linkage gear 39. The tension cylinder 41 makes the deformation of the toothed belt 37 more stable, making the transmission between the toothed belt 37 and the linkage gear 39 more stable, reducing the wear between the toothed belt 37 and the surface of the linkage plate 23, and improving the service life of the toothed belt 37.

[0053] Reference Figures 3 to 4 Each linkage gear 39 is meshed with a drive gear 42 on the side facing the linkage plate 23;

[0054] Adding a drive gear 42 provides more space for the working space of the linkage gear 39, thereby giving the shelf 12, which is connected to the linkage gear 39, more room to rotate. This prevents the shelf box 13 on the shelf 12 from interfering with the inner wall of the refrigerator 11, and allows the shelf 12 to be used with a larger shelf box 13. In addition, it reduces the bending deformation of the toothed belt 37 towards the linkage gear 39, allowing the transmission force of the toothed belt 37 to be better transmitted to the linkage gear 39, thus enabling the linkage gear 39 to rotate more stably.

[0055] Reference Figures 1 to 3 Each pedal 21 is fixedly connected with an anti-slip pad 16;

[0056] The addition of anti-slip mat 16 makes it less likely for users to slip when stepping on pedal 21, increases the force of the user's foot on pedal 21, and allows the user to apply more force to pedal 21.
