Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a microporous plate centrifuge that facilitates the fixing of different microporous plates. Background Technology

[0002] Microplates, also known as multiwell plates or microwell array plates, are meticulously designed plates with a surface covered with numerous tiny, uniformly distributed pores. These pores are typically precise to the micrometer level, enabling microplates to serve as highly efficient sample processing and reaction platforms. Microplates play a crucial role in scientific research, medical diagnostics, biological experiments, drug screening, environmental monitoring, and numerous biochemical applications. Their overall design considers not only the size and distribution of the pores but also the material of the plate, surface treatment technology, and compatibility with other experimental equipment. Microplates are made from a variety of materials, including but not limited to plastics, glass, ceramics, and metals, each with unique chemical and physical properties to meet the needs of different experiments. In biological experiments, microplates are commonly used as carriers for cell culture, enzyme-linked immunosorbent assays (ELISA), and polymerase chain reaction (PCR). Each microwell can function as an independent reaction unit, processing multiple samples simultaneously, significantly improving experimental throughput and efficiency. Furthermore, microplates are easily integrated with automated experimental equipment, enabling automated and intelligent experimental procedures.

[0003] A microplate centrifuge is a centrifugation device specifically designed for microplates. It utilizes centrifugal force to rapidly settle the liquid within the microplate, preventing air bubbles or sample loss and ensuring the homogeneity and integrity of experimental samples. This equipment is widely used in PCR experiments, DNA / RNA extraction and purification, enzyme reactions, protein crystallization, cell culture, and other fields.

[0004] When using microplate centrifuges, ensuring the efficiency of the centrifuge is crucial, and securing microplates of different sizes is particularly important. However, traditional microplate centrifuges simply insert the microplate directly into the slots and then start the centrifuge. This method is not convenient for securing and supporting microplates of different widths and lacks adjustment functionality, which greatly reduces the ease of use of the centrifuge and makes it extremely inconvenient. Therefore, there is an urgent need for a microplate centrifuge that can easily secure different microplates to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a microplate centrifuge that facilitates the fixing of different microplates, solving the problem that in the prior art, microplate centrifuges simply insert the microplate into the slot and then start the centrifuge for centrifugation, which is not convenient for fixing and supporting microplates of different widths, lacks adjustment function, and thus greatly reduces the ease of use of the centrifuge.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A microplate centrifuge for easy fixation of different microplates includes a frame, a support rod rotatably connected to the inner side of the frame, a drive motor fixedly connected to the bottom side of the frame by bolts, and the bottom end of the support rod passing through the bottom of the frame and being connected to the output shaft of the drive motor for transmission. Several support frames are fixedly connected to the support rod.

[0008] A side filter plate is provided on one side of the support frame, and insert plates are fixedly connected to both ends of the side filter plate. Both insert plates penetrate the side wall of the support frame. An inner filter plate is fixedly connected to one side of the support frame, and a side frame is provided on one side of the support frame. The two sides of the side frame are fixedly connected to one side of the two insert plates respectively. The two sides of the side frame are elastically connected to one side of the support frame. An adsorption cylinder is fixedly connected to the inner wall of the frame.

[0009] Preferably, a sliding sleeve is fitted on the upper part of the bearing rod, and a limiting plate is fitted on the outer side of the sliding sleeve, and the limiting plate is located at the top of all bearing frames.

[0010] Preferably, a threaded rod is provided on one side of the sliding sleeve, and one end of the threaded rod has a threaded groove that passes through both sides of the sliding sleeve and the bearing rod in sequence.

[0011] Preferably, all insert plates pass through the side walls of all the load-bearing frames sequentially via slots.

[0012] Preferably, each of the support frames is provided with a screw on one side, and one end of the screw passes through the side wall of the support frame and the corresponding insert plate in sequence through a screw groove.

[0013] Preferably, the bottom end of the support rod passes through the bottom of the frame through a bearing sleeve, and the top of the frame is rotatably connected to a top cover via a hinge.

[0014] Preferably, the inner sides of all the side frames are elastically connected to the side walls of all the load-bearing frames by several tension springs.

[0015] Preferably, each screw has several screw slots on one side of the insert plate.

[0016] This utility model has the following beneficial effects:

[0017] This microplate centrifuge, designed for easy fixation of different microplates, achieves flexible fixation of microplates of varying sizes through the adjustable design of the side and inner filter plates on the support frame, and the elastic connection between the side frame and the support frame. This solves the problem of traditional microplate centrifuges being unable to adapt to microplates of different widths due to their single fixation method, greatly improving the centrifuge's ease of use and applicability. Simultaneously, the transmission connection between the drive motor and the support rod, along with the centrifugal force generated during the rotation of the support frame, ensures rapid sedimentation and separation of the liquid within the microplate. This not only improves the processing efficiency and uniformity of experimental samples but also avoids the impact of air bubbles or sample loss on experimental results. Furthermore, the adsorption cylinder on the inner wall of the frame further enhances the cleanliness of the centrifugation environment, providing more reliable conditions for experiments.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] Reference Figure 1 -8. A microplate centrifuge for easy fixing of different microplates includes a frame 1. A support rod 10 is rotatably connected to the inner side of the frame 1. A drive motor 2 is fixedly connected to the bottom side of the frame 1 by bolts. The bottom end of the support rod 10 passes through the bottom of the frame 1 and is connected to the output shaft of the drive motor 2. The support rod 10 is an important bridge connecting the drive motor 2 and the support frame 8. It not only transmits the rotational power of the drive motor 2, but also realizes the stable bearing and rotation of the microplate through the support frame 8 fixedly connected to it. Several support frames 8 are fixedly connected to the support rod 10.

[0030] A side filter plate 9 is provided on one side of the support frame 8, and insert plates 11 are fixedly connected to both ends of the side filter plate 9. Both insert plates 11 penetrate through the side wall of the support frame 8. An inner filter plate 14 is fixedly connected to one side of the support frame 8. As the direct support structure for the microporous plate, the design of the support frame 8 fully considers the fixation and adaptability of the microporous plate. The side filter plate 9 on one side, through the through connection of the insert plates 11 to the side wall of the support frame 8, allows for flexible adjustment of the position of the side filter plate 9 to accommodate microporous plates of different widths. At the same time, an inner filter plate is also fixedly connected to one side of the support frame 8. 14, together with the side filter plate 9, constitutes a stable fixing structure for the microporous plate. A side frame 12 is provided on one side of the support frame 8, and the two sides of the side frame 12 are fixedly connected to one side of the two insert plates 11 respectively. Both sides of the side frame 12 are elastically connected to one side of the support frame 8. The insert plates 11 also achieve stable fixing and limiting of the side filter plate 9 through the fixed connection with the side frame 12 and the cooperation of the screw groove 16 and the screw 15. An adsorption cylinder 4 is fixedly connected to the inner wall of the frame 1. The liquid centrifuged from the microporous plate can be adsorbed by the adsorption cylinder 4.

[0031] Furthermore, a sliding sleeve 6 is fitted on the upper part of the support rod 10, and a limiting plate 5 is fitted on the outer side of the sliding sleeve 6. The limiting plate 5 is located on the top of all the support frames 8. When the support frames 8 are adjusted according to the microporous plate specifications, the sliding sleeve 6 can slide along the support rod 10 to the appropriate position and limit the top of all the support frames 8 through the limiting plate 5, ensuring the stability of the support frames 8 and the microporous plate during centrifugation, thereby enhancing the overall structural stability and preventing the microporous plate from shaking or falling off.

[0032] Furthermore, a threaded rod 7 is provided on one side of the sliding sleeve 6, and one end of the threaded rod 7 has a threaded groove that passes through both sides of the sliding sleeve 6 and the bearing rod 10 in sequence. Tightening the threaded rod 7 can fix the sliding sleeve 6 and the limiting plate 5 at a specific position on the bearing rod 10, ensuring the durability of the limiting effect. This achieves the effect of conveniently adjusting and fixing the position of the sliding sleeve 6 and the limiting plate 5, and improving the ease of operation.

[0033] Furthermore, all the insert plates 11 pass through the side walls of all the support frames 8 in sequence via the slots 17, so that the insert plates 11 can slide smoothly in the side walls of the support frames 8 and adjust their positions according to the width of the microporous plate, thereby achieving the effect of flexibly adapting to microporous plates of different specifications and improving the versatility of the equipment.

[0034] Furthermore, each of the support frames 8 is provided with a screw 15 on one side, and one end of the screw 15 passes through the side wall of the support frame 8 and the corresponding insert plate 11 in sequence through the screw groove 16. Tightening the screw 15 can limit and fix the adjusted insert plate 11, ensuring the stability of the side filter plate 9, and achieving the effect of firmly fixing the side filter plate 9 and preventing the microporous plate from shifting during centrifugation.

[0035] Furthermore, the bottom end of the support rod 10 passes through the bottom of the frame 1 through a bearing sleeve, and the top of the frame 1 is rotatably connected to the top cover 3 through a hinge. The bearing sleeve ensures the smooth rotation of the support rod 10, while the top cover 3 can be opened or closed when needed, making it convenient to place or remove the microplate, thus ensuring the normal operation of the equipment and facilitating operation.

[0036] Furthermore, the inner sides of all the side frames 12 are elastically connected to the side walls of all the bearing frames 8 by several tension springs 13. The tension springs 13 provide elastic support for the side frames 12, so that the side filter plates 9 can fit tightly against the microporous plates of different widths, while ensuring the stability of the side frames 12 during the adjustment process, thereby improving the fixing effect and enhancing the adaptability of the equipment.

[0037] Furthermore, each of the screws 15 has several screw grooves 16 on one side of the insert plate 11, allowing the screws 15 to be screwed into different positions of the screw grooves 16 as needed. This further improves the adjustment accuracy and fixing stability of the insert plate 11 and the side filter plate 9, achieving the effect of finely adjusting the position of the side filter plate 9 and ensuring the optimal fixing effect of the microporous plate.

[0038] In summary:

[0039] When using this type of microplate centrifuge that facilitates the fixing of different microplates, a series of adjustments must first be made according to the specifications of the microplate to be centrifuged. The specific operation process is as follows: Adjust the distance between the side filter plate 9 and the inner filter plate 14 on the support frame 8 through the elastic connection provided by the tension spring 13 between the side frame 12 and the support frame 8. This adjustment allows the two insert plates 11 to slide smoothly through the slots 17 in the side wall of the support frame 8 and be fixed in a suitable position according to the width of the microplate, thus achieving flexible adaptation to microplates of different specifications. After the adjustment is completed, place the microplate inside the support frame 8. At this time, the side filter plate 9, the inner filter plate 14, and the support frame 8 itself together form a stable fixing structure. To further enhance the stability of this fixing structure, screws 15 are screwed into several screw grooves 16 on the insert plates 11 to limit the position of the insert plates 11, i.e., the side filter plates 9. Simultaneously, the sliding sleeve 6 fitted on the upper part of the support rod 10 can slide along the support rod 10 to an appropriate position, and the limiting plate 5 fitted on its outer side limits the top of all the support frames 8. Tighten the threaded rod 7 on one side of the sliding sleeve 6, so that one end passes through the threaded groove through both sides of the sliding sleeve 6 and the support rod 10 in sequence, fixing the sliding sleeve 6 and the limiting plate 5 at a specific position on the support rod 10, thereby ensuring the stability of the support frames 8 and the microplate during centrifugation. Then, start the drive motor 2, which is fixed to the bottom of the frame 1 by bolts. The output shaft of the drive motor 2 drives the support rod 10 to rotate inside the frame 1 through the transmission connection. Several support frames 8 on the support rod 10 and the microplate inside them also rotate, generating centrifugal force. This centrifugal force causes the liquid in the microplate to settle rapidly, separating different components in the liquid or removing air bubbles, thereby ensuring the uniformity and integrity of the experimental samples. During centrifugation, the adsorption cylinder 4 on the inner wall of the frame 1 can further assist in adsorbing any splashes or impurities that may be generated inside the microplate, keeping the centrifugation environment clean. Meanwhile, the bottom end of the support rod 10 passes through the bottom of the frame 1 via a bearing sleeve, ensuring smooth rotation of the support rod 10. The top cover 3, which is hinged to the top of the frame 1, can be easily opened or closed when needed, facilitating the placement or removal of the microporous plate.
