Description

Technical Field

[0001] This application relates to the technical field of organ-on-a-chip, and more particularly to a culture device. Background Technology

[0002] Organ-on-a-chip and organoid culture technologies are important tools in biomedical research. By simulating the microenvironment of human organs, they are used for drug screening, toxicity testing, and disease mechanism research. These culture systems require precise control of fluid, mechanical, and biochemical conditions, thus demanding extremely high stability and ease of operation from the culture chamber. Currently, organ-on-a-chip culture is mostly carried out in specific culture equipment that provides the necessary growth conditions, such as carbon dioxide concentration, temperature, and humidity.

[0003] Culture equipment mainly includes culture devices, culture boxes, and brackets for placing the culture boxes within the culture devices. Common brackets often use mechanical snap-fit ​​mechanisms, consisting of a snap-fit ​​body and an elastic arm. The snap-fit ​​body has a placement part for placing the culture box, and the elastic arm is an integrally formed elastic snap-fit ​​structure with barbs. The culture device has a matching groove, and the elastic arm snaps into the matching groove to lock the snap-fit ​​body. However, mechanical snap-fit ​​mechanisms have the problem of insufficient stability because they are prone to loosening under vibration, causing the culture box to shift, resulting in cell damage or data deviation.

[0004] Therefore, there is an urgent need for a culture device to solve the problem that traditional mechanical clips are prone to loosening and displacement of the culture box under vibration, effectively avoid cell shear force damage and experimental data deviation caused by the movement of the culture box, and significantly improve the stability and reproducibility of organoid culture. Summary of the Invention

[0005] This application provides a culture device to solve the problem that traditional mechanical clips are prone to loosening and displacement of the culture box under vibration. It effectively avoids cell shear force damage and experimental data deviation caused by the movement of the culture box, and significantly improves the stability and reproducibility of organoid culture.

[0006] This application provides a culture device, which includes:

[0007] A culture machine platform, which has tracks;

[0008] The support frame has a mounting part for placing the culture box, and the support frame slides with the track;

[0009] A magnetic component is disposed on the support frame and is used to magnetically attract the support frame to a predetermined position in the culture device.

[0010] In one possible implementation, this application also proposes that a protrusion is provided at one end of the support frame along the first direction, and the protrusion has a magnetic groove for accommodating a magnetic component, wherein the magnetic component is fixedly disposed in the magnetic groove.

[0011] In one possible implementation, this application also proposes that a plurality of magnetic elements be spaced apart along a second direction.

[0012] In one possible implementation, this application also proposes that the support frame has through holes to form a mounting portion.

[0013] In one possible implementation, this application also proposes that the through hole is provided with a support block for supporting the culture box along the first direction.

[0014] In one possible implementation, this application also proposes that the through hole is provided with a limiting block along the second direction for restricting the movement of the culture box along the first direction.

[0015] In one possible implementation, this application also proposes that the top of the limiting block protrudes upward to form a limiting portion.

[0016] In one possible implementation, this application also proposes that the culture machine platform has a groove to form a track.

[0017] In one possible implementation, this application also proposes that the support frame is provided with a foolproof protrusion on the outer side along the second direction, and the side wall of the slide groove is provided with a groove that cooperates with the foolproof protrusion.

[0018] In one possible implementation, this application also proposes that a handle be provided at the end of the support frame away from the magnetic component.

[0019] The culture device provided in this application embodiment uses magnetic components to magnetically fix the support frame to a predetermined position on the culture machine, replacing the traditional mechanical buckle structure. This avoids the positioning failure problem caused by the plastic deformation of the elastic arm, and has the advantages of improving the positioning stability of the culture box, reducing the risk of displacement and falling off, extending the service life, and saving operating space.

[0025] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0026] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0027] In related technologies, organ-on-a-chip and organoid culture technologies rely on mechanical clips to fix culture boxes. However, these mechanical clips are prone to loosening under vibration, causing displacement of the culture box, resulting in cell shear force damage and experimental data deviation. For example, when a bracket using elastic arm clips is subjected to external forces during equipment operation or transportation, the elastic arm is prone to deformation and detachment from the mating groove, causing the culture box to shift position and affecting the stability of microenvironment control.

[0028] To address the aforementioned problems, the inventors discovered that the physical deformation of mechanical clips is the core factor leading to fixation failure, and thus considered how to eliminate the risk of deformation through non-contact fixation. A fixation method based on the principle of magnetic attraction can avoid stress relaxation caused by mechanical contact while maintaining detachability. By combining the magnetic structure with a sliding track, both rapid positioning and stable fixation can be achieved, ultimately forming a technical solution where magnetic components and the track work synergistically.

[0029] Therefore, this application proposes a culture device including a culture platform, a support frame, and a magnetic component. The culture platform has a track, and the support frame is provided with a placement part for placing the culture box and slidingly engaging with the track. The magnetic component is disposed on the support frame to magnetically attract it to a predetermined position. By magnetically fixing the support frame to the predetermined position on the culture platform using the magnetic component, the traditional mechanical snap-fit ​​structure is replaced, avoiding positioning failure caused by plastic deformation of the elastic arm. This has the advantages of improving the positioning stability of the culture box, reducing the risk of displacement and detachment, extending service life, and saving operating space.

[0030] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0031] Combination Figures 1 to 3 This application provides a culture device, which includes a culture platform 100, a support frame 300, and a magnetic component 200. Wherein, x is a first direction (the length direction of the support frame 300), and y is a second direction (the width direction of the support frame 300).

[0032] The culture platform 100 serves as the main structure of the culture apparatus. It includes a lower support platform, a support frame, and an upper support platform. The upper support platform supports the gas guide component. The support frame has a vertically extending slide rail, within which the gas guide component is slidably mounted. A lifting mechanism is installed on the support frame to drive the gas guide component to descend or rise vertically. The culture box 400 is mounted on the lower support platform via a support frame 300. A groove or raised rail is provided on the lower support platform to form a track, guiding the directional movement of the support frame 300.

[0033] The support frame 300 is a support structure for supporting the culture box 400. The bottom of the support frame 300 can be equipped with sliders or rollers to cooperate with the track to achieve linear sliding.

[0034] The magnetic component 200 is a functional element that can generate magnetic attraction force. Specifically, it can be a permanent magnet. By embedding it into a specific position of the support frame 300, it can generate an attraction force with the metal parts of the culture machine platform 100 or the complementary magnetic component 200, thereby fixing the support frame 300 in the target area.

[0035] Specifically, the track of the culture platform 100 restricts the movement direction of the support frame 300 through a sliding groove or convex rail structure. After the support frame 300 slides along the track to a predetermined position, the magnetic component 200 generates a magnetic attraction force with the corresponding area of ​​the culture platform 100, achieving contactless fixation. For example, when the support frame 300 slides to the culture area of ​​the culture platform 100, the magnetic component 200 attracts the magnetic plate built into the platform, preventing the culture box 400 from shifting due to liquid flow or equipment vibration. The placement part accommodates the culture box 400 through a through hole 301 or a groove structure, maintaining a stable spatial position in the fixed state.

[0036] In related technologies, existing mechanical latches rely on the deformation of elastic arms to achieve locking, which can easily lead to material fatigue with long-term use. Magnetic fixation, on the other hand, does not require physical deformation, significantly reducing the risk of loosening. In addition, the combination of sliding rails and magnetic fixation allows for rapid positioning and release, avoiding mechanical impact on the culture box 400 caused by repeated operations.

[0037] Through the above technical solution, this application effectively solves the problem of displacement of culture box 400 under vibration environment. The magnetic fixation eliminates the risk of deformation failure of mechanical buckles, ensures that culture box 400 remains stable in fluid dynamic environment, avoids cell damage due to shear force, and improves the reproducibility of experimental data.

[0038] This application further proposes that the support frame 300 has a protrusion 302 at one end along the first direction, and the protrusion 302 has a magnetic groove for accommodating the magnetic component 200, and the magnetic component 200 is fixedly disposed in the magnetic groove.

[0039] The support frame 300 is a frame structure used to support the culture box 400. It can be made of metal or plastic and is connected to the track of the culture machine platform 100 through a sliding fit, so as to stably support the culture box 400.

[0040] The protrusion 302 is a partial extension of the support frame 300 at its end in the first direction. It can be integrally formed with the support frame 300 or installed as a separate component, further increasing the contact area between the magnetic component 200 and the culture device. The magnetic groove is a recessed space formed inward from the protrusion 302, providing a mounting position for the magnetic component 200 and preventing it from shifting due to vibration. The magnetic component 200 is a component capable of generating magnetic attraction, specifically using a neodymium iron boron permanent magnet or an electromagnet. Its function is to fix the support frame 300 to a predetermined position in the culture device through magnetic attraction.

[0041] Specifically, a protrusion 302 is provided at one end of the support frame 300 along the first direction, and a handle 800 is provided at the other end. A magnetic groove is formed in the protrusion 302, and a magnetic component 200 is embedded in the magnetic groove. When the support frame 300 slides to the predetermined position of the culture device via the track, the magnetic component 200 directly contacts the metal surface of the culture device or another magnetic component 200, and is fixed by magnetic attraction. Due to the spatial constraint of the magnetic groove on the magnetic component 200, the magnetic component 200 will not shift under vibration, thereby ensuring the connection stability between the support frame 300 and the culture device.

[0042] In related technologies, existing mechanical latches rely on the deformation of an elastic arm to generate locking force, which is prone to loosening due to elastic fatigue under vibration. In contrast, this application uses a magnetic fixing method, eliminating the need for an elastic structure. The magnetic force is evenly distributed on the contact surface, effectively resisting vibration interference. Furthermore, the magnetic groove's limiting effect on the magnetic component 200 avoids the magnetic misalignment problem caused by inaccurate installation of the magnetic component 200 in traditional magnetic structures.

[0043] Through the above technical solution, this application solves the problem that traditional mechanical buckles are prone to loosening under vibration, causing displacement of the culture box 400. By cooperating with the magnetic groove and the magnetic component 200, the support frame 300 is stably fixed in the predetermined position, which improves the positioning accuracy of the culture box 400 in dynamic environment and avoids cell damage or experimental data deviation caused by displacement.

[0044] This application further proposes that the magnetic element 200 is provided with a plurality of magnetic elements spaced apart along the second direction.

[0045] In this scheme, multiple magnetic components 200 are arranged at intervals in the second direction in a horizontal direction perpendicular to the first direction. Specifically, this can be achieved by setting multiple magnetic components 200 on the same side of the support frame 300, so that the magnetic attraction force is distributed at multiple points in the second direction. In this scheme, two magnetic components 200 are arranged at intervals along the second direction, and two magnetic attraction slots are also set accordingly. The two magnetic components 200 are respectively set in the corresponding magnetic attraction slots.

[0046] Specifically, during the installation of the support frame 300 onto the culture platform 100, multiple magnetic components 200 simultaneously magnetically attract the metal structure of the culture platform 100. Since the magnetic components 200 are spaced apart along the second direction, the magnetic attraction forms multiple fixed points along the length of the support frame 300. This allows the attraction forces at each magnetic point to collectively counteract any displacement tendency when the support frame 300 is subjected to vibration or external force. When the support frame 300 slides along the track to the predetermined position, the multiple magnetic components 200 simultaneously generate an attraction effect, forming a planar fixing effect and avoiding localized stress concentration that might occur with single-point magnetic attraction.

[0047] In related technologies, existing mechanical buckles rely solely on a single engagement point of the elastic arm for fixation, which can easily lead to overall displacement due to single-point failure under vibration. This solution, however, utilizes multiple magnetic adsorption points distributed along the second direction to create a redundant distribution of the fixing force of the support frame 300 in the horizontal direction. Even if individual magnetic components 200 momentarily detach due to vibration, the remaining magnetic components 200 can still maintain effective fixation, significantly improving vibration resistance.

[0048] Through the above technical solution, this application can effectively prevent the support frame 300 from shifting laterally under vibration, ensure that the culture box 400 remains stable in a dynamic environment, and avoid cell shear force damage and experimental data acquisition errors caused by displacement.

[0049] This application further proposes that the support frame 300 has a through hole 301 to form a mounting part.

[0050] Among them, the through hole 301 is a hole structure that penetrates the thickness of the support frame 300. It can be made by stamping or mechanical cutting and is used to directly accommodate the bottom area of ​​the culture box 400.

[0051] The placement section is a support area formed by the edge of the through hole 301. Specifically, it can be achieved by adjusting the size of the through hole 301 to match the outer contour of the culture box 400, which is used to limit the horizontal displacement of the culture box 400.

[0052] Specifically, the inner wall contour of the through hole 301 forms a clearance fit with the outer wall of the culture box 400. When the culture box 400 is inserted into the through hole 301, its bottom edge is circumferentially surrounded by the through hole 301, thereby restricting lateral movement. The depth of the through hole 301 can be set to fully penetrate or partially penetrate the support frame 300 according to the height of the culture box 400, so that the bottom surface of the culture box 400 is in contact with or suspended from the culture platform 100. This structure does not require additional snap-fit ​​components and directly fixes the position of the culture box 400 through geometric constraints.

[0053] In related technologies, existing mechanical latches rely on the deformation of elastic arms to generate clamping force, which is prone to stress relaxation and clamping failure under vibration. The rigid constraint structure formed by the through hole 301 eliminates the risk of failure of elastic components, directly restricts displacement through geometric matching, and simplifies the processing of the support frame 300.

[0054] Through the above technical solution, this application avoids the problem of clamping force attenuation caused by vibration of the elastic buckle, and improves the positional stability of the culture box 400 within the through hole 301, effectively preventing shear force damage caused by displacement during cell culture. The through hole 301 structure also reduces the number of components in the support frame 300, facilitating cleaning and sterilization operations.

[0055] This application further proposes that the through hole 301 is provided with a support block 500 for supporting the culture box 400 along the first direction.

[0056] Among them, the through hole 301 is a through hole structure opened on the support frame 300. Specifically, it can be a rectangular, circular or irregular through hole 301, used to accommodate the bottom or side of the culture box 400.

[0057] The support block 500 is a protruding structure extending along the inner wall of the through hole 301 in the first direction. It can be made of metal or plastic and is used to directly contact and support the bottom edge of the culture box 400 to prevent the culture box 400 from sliding along the thickness direction of the support frame 300 within the through hole 301.

[0058] Specifically, bearing blocks 500 are provided on both sides of the inner wall of the through hole 301 in the first direction. When the culture box 400 is placed in the through hole 301, its bottom edge contacts the upper surface of the bearing block 500. When the support frame 300 slides along the track or is subjected to external vibration, the bearing block 500 restricts the vertical displacement of the culture box 400 through physical support, and at the same time disperses the weight load of the culture box 400 by increasing the contact area, avoiding structural deformation caused by local stress concentration.

[0059] In related technologies, existing brackets typically rely solely on the clamping force of elastic clips to fix the culture box 400. Under vibration, the culture box 400 is prone to displacement due to fatigue or loosening of the elastic arm. In contrast, this solution provides rigid support through the bearing block 500, forming a stable contact surface at the bottom of the culture box 400 and reducing the risk of slippage.

[0060] Through the above technical solution, this application can effectively limit the movement of the culture box 400 in the vertical direction, avoid the culture box 400 from tilting or falling off due to the sliding of the support frame 300 or external vibration, thereby reducing the risk of damage caused by shear force during cell culture and improving the reliability of experimental data.

[0061] This application further proposes that a limiting block be provided in the through hole 301 along the second direction, the limiting block being used to restrict the movement of the culture box 400 along the first direction.

[0062] The through hole 301 is a through-hole structure opened on the support frame 300, which can be rectangular, circular or irregularly shaped, used to accommodate the culture box 400 and allow it to be positioned vertically. The limiting block is a rigid blocking structure fixed to the side wall of the through hole 301, which can be made of metal or plastic, and restricts the displacement of the culture box 400 along the first direction through mechanical constraint.

[0063] Specifically, limiting blocks are respectively provided at both ends of the sidewall of the through hole 301 in the second direction. When the culture box 400 is inserted into the through hole 301, the limiting blocks contact the side of the culture box 400 to form a rigid barrier. When the support frame 300 moves along the track or is subjected to external vibration, the limiting blocks prevent the culture box 400 from displacing along the sliding axis through physical contact, thereby maintaining the fixed position of the culture box 400 in the through hole 301.

[0064] In related technologies, existing elastic buckles rely on a barbed structure to provide unidirectional constraint, which is prone to failure due to material deformation under vibration. In contrast, the limiting block adopts a rigid blocking mechanism, forming a stable mechanical constraint through bidirectional contact surfaces, thus avoiding the risk of loosening caused by elastic deformation.

[0065] Through the above technical solution, this application effectively eliminates the displacement of the culture box 400 along the sliding axis during operation or vibration, ensuring that the culture box 400 always maintains the predetermined position within the through hole 301, avoiding cell shear force damage and experimental data deviation caused by displacement, and improving the stability and reproducibility of the culture process.

[0066] This application further proposes that the top of the limiting block protrudes upward to form a limiting part 601.

[0067] The limiting block is a structural component set in the through hole 301 along the second direction. Specifically, it can be made of metal or plastic and fixed to the support frame 300 by injection molding or welding to limit the movement of the culture box 400 along the first direction.

[0068] The limiting part 601 is a protruding structure formed by extending upward from the top of the limiting block. Specifically, it can be formed by injection molding or machining. It is used to prevent the culture box 400 from moving away from the predetermined position along the thickness direction of the support frame 300 when subjected to external force.

[0069] Specifically, a limiting block is provided along the second direction within the through hole 301 of the support frame 300, with the top of the limiting block protruding upward to form a limiting portion 601. When the culture box 400 is placed within the through hole 301, its sidewall contacts the limiting portion 601 of the limiting block, and the limiting portion 601 prevents the culture box 400 from sliding along the thickness direction of the support frame 300 by physical blocking. For example, when the culture device is subjected to vibration or tilting, the contact surface between the limiting portion 601 and the sidewall of the culture box 400 generates static friction, thereby counteracting the displacement tendency of the culture box 400.

[0070] In related technologies, traditional mechanical latches rely on the barbed structure of an elastic arm to achieve locking. However, the elastic arm is prone to elastic deformation under vibration, leading to loosening. This solution adopts a combination structure of a rigid limiting block and a limiting part 601, which directly restricts the movement direction of the culture box 400 through physical contact, without relying on elastic deformation, thus avoiding locking failure due to material fatigue or vibration.

[0071] Through the above technical solution, this application effectively prevents the culture box 400 from undergoing relative displacement under vibration or external force, ensuring that the culture box 400 remains stable in a dynamic environment and avoiding cell shear force damage or experimental data deviation caused by displacement.

[0072] This application further proposes that the culture machine platform 100 has a groove to form a track.

[0073] The chute is a groove structure formed on the lower support platform of the culture machine 100, which can be realized by machining or injection molding, and is used to provide a sliding path for the support frame 300. The track is a guide structure formed by the chute, which limits the movement direction of the support frame 300, ensuring that it maintains a stable trajectory during sliding and avoiding deviation caused by external vibration.

[0074] Specifically, a chute is formed along the first direction on the lower support platform, and its width matches the sliding component of the support frame 300. When the support frame 300 engages with the chute, the sliding component is embedded inside the chute and moves along the length of the chute. The sidewalls of the chute physically limit the sliding component, restricting the displacement of the support frame 300 perpendicular to the sliding direction. Thus, the sliding process of the support frame 300 on the culture machine platform 100 is strictly constrained within the path defined by the chute, preventing accidental detachment due to vibration or operational errors.

[0075] In related technologies, existing mechanical latches rely on the locking mechanism of an elastic arm and a mating groove, which is prone to loosening due to elastic deformation under vibration. In contrast, the engagement between the slide groove and the sliding component is achieved through the physical restraint of a rigid structure, eliminating the need for elastic deformation and significantly reducing the risk of the support frame shifting by 300° due to vibration. Furthermore, the slide groove structure offers higher controllability in machining precision, ensuring consistent sliding trajectories and improving operational reliability.

[0076] Through the above technical solution, this application solves the problem of instability of the support frame 300 caused by vibration in traditional mechanical fasteners. The rigid fit between the sliding groove and the sliding component precisely restricts the movement path of the support frame 300 on the culture platform 100, thereby preventing displacement of the culture box 400 under vibration and reducing cell shear force damage and experimental data deviation. Simultaneously, the sliding groove structure simplifies the installation process, eliminating the need for complex fastener operations to position and fix the support frame 300.

[0077] This application further proposes that the support frame 300 is provided with a foolproof protrusion 700 on the outer side along the second direction, and the side wall of the slide is provided with a groove that cooperates with the foolproof protrusion 700.

[0078] The anti-misalignment bump 700 is a raised structure located on the outside of the support frame 300. It can be implemented using a rectangular, trapezoidal, or other irregularly shaped block, with its height and width forming a clearance fit with the groove. The groove is a recessed structure formed on the side wall of the slide groove, which can be formed by milling. Its depth and width match the anti-misalignment bump 700. The fit between the anti-misalignment bump 700 and the groove restricts the installation direction of the support frame 300 within the slide groove, preventing reverse or offset installation.

[0079] Specifically, as the support frame 300 moves along the slide groove, the anti-misalignment protrusion 700 engages with the groove to create a physical limit. During installation, if the support frame 300 is not inserted in the predetermined direction, the anti-misalignment protrusion 700 will interfere with the sidewall of the slide groove, preventing the frame from sliding further. When the frame is correctly aligned, the anti-misalignment protrusion 700 is embedded in the groove, at which point the frame can move smoothly along the slide groove. This structure forcibly limits the installation direction through mechanical interference, eliminating the risk of frame misalignment caused by operational errors.

[0080] In some specific embodiments, the anti-misalignment bump 700 can be configured as a single unidirectional bump, with a corresponding unidirectional groove structure; alternatively, the anti-misalignment bump 700 can be symmetrically distributed on both sides of the support frame 300, with the corresponding symmetrical double-groove structure. For example, the anti-misalignment bump 700 adopts a chamfered design, with its top edge rounded to facilitate guiding the bump into the groove during correct alignment. Furthermore, a guide slope can be provided at the opening end of the groove to further reduce assembly resistance.

[0081] In related technologies, existing mechanical latches rely on the deformation of an elastic arm to achieve locking, which is prone to failure due to material fatigue in vibration environments. This solution uses the physical limiting of the anti-misalignment protrusion 700 and the groove, eliminating the need for elastic deformation and maintaining a stable locked position even under vibration conditions. Furthermore, the anti-misalignment structure constrains the installation direction through geometric shape, significantly reducing the probability of misoperation compared to traditional latches that rely on manual alignment judgment.

[0082] Through the above technical solution, this application effectively solves the problem of slide block jamming caused by incorrect installation direction of the support frame 300, and avoids positional deviation of the culture box 400 caused by frame offset. The rigid fit between the anti-fooling protrusion 700 and the groove ensures that the frame can maintain a stable sliding trajectory under vibration environment, thereby ensuring the mechanical stability of the cell microenvironment inside the culture box 400 and reducing experimental data errors caused by device displacement.

[0083] This application further proposes that a handle 800 be provided at the end of the support frame 300 away from the magnetic component 200.

[0084] The support frame 300 is a frame structure used to support the culture box 400. It can be made of metal or plastic and is connected to the track of the culture machine platform 100 through a sliding fit, thus providing stable support for the culture box 400.

[0085] The handle 800 is a gripping component for manual operation. It can be a separate component, using an arc or U-shaped part, and is fixed to the end of the support frame 300 by welding or bolting. This facilitates the application of force when moving the support frame 300 and improves the ease of operation. Alternatively, the handle 800 can be designed with a hollowed-out design on the support frame 300 to provide space for the operator's hand to grip.

[0086] Specifically, a handle 800 is provided at the end of the support frame 300 away from the magnetic component 200. The operator can apply pushing or pulling force by gripping this component, causing the support frame 300 to slide along the track. When it is necessary to remove the support frame 300 from the culture device, the handle 800 can be pulled directly to release the magnetic fixation. When it is necessary to push the support frame 300 into the culture device, pushing force is applied through the handle 800 to move it along the track to the predetermined position, where it is automatically fixed by the magnetic component 200. This design eliminates the need for complex mechanical structures during the movement of the support frame 300, while also preventing frame tilting or jamming due to improper operation.

[0087] In related technologies, existing mechanical latches require precise alignment of the elastic arm and the mating groove to lock, which is cumbersome and prone to disengagement due to vibration. This solution, however, simplifies the operation process by using the handle 800 in conjunction with the magnetic component 200, achieving stable fixation through magnetic attraction and effectively reducing the risk of displacement caused by accidental contact or vibration.

[0088] Through the above technical solution, this application can significantly improve the ease of operation of the culture box 400 bracket, reduce the positional displacement of the culture box 400 caused by unstable frame movement, and thus avoid experimental data errors caused by shear force damage during cell culture.

[0089] Finally, it should be noted that other embodiments of the invention will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein. This invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein, and is not limited to the precise structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of the invention is limited only by the appended claims.
