Description

Technical Field

[0001] This utility model relates to the field of laboratory instrument technology, and in particular to an adjustable vortex mixer centrifuge tube adapter. Background Technology

[0002] Centrifuge tube adapters are essential accessories for centrifuges, used to secure centrifuge tubes for proper mixing. They are available in various sizes to accommodate different capacities. Made from diverse materials, such as plastic or metal, they securely hold the centrifuge tubes in place using clips, clamps, or slots to prevent them from shifting or falling off during mixing.

[0003] A high-speed circular motion is generated by an eccentric wheel driven by a motor, causing the adapter to vibrate rapidly. This vibration is transmitted to the centrifuge tube, causing the liquid inside to form a strong vortex under the action of centrifugal force and inertial force, thus achieving rapid mixing. High-frequency vibration can also create three-dimensional vortices inside the liquid, accelerating molecular diffusion and substance dissolution. In the biomedical field, this can be used for mixing reaction systems and reconstitute reagents in PCR experiments. In cell culture experiments, it can thoroughly mix cells with the culture medium, ensuring that the cells receive sufficient nutrients.

[0004] In existing technologies, manually shaking centrifuge tubes for mixing increases the labor intensity of experimenters, and prolonged operation can easily lead to fatigue, affecting the stability and consistency of the operation. It is also difficult to quickly dissolve these samples, which can affect subsequent experimental steps. Especially for experiments that require high mixing uniformity, such as PCR reaction system mixing, it can lead to amplification failure. To address these issues, an adjustable vortex mixer centrifuge tube adapter is proposed. Utility Model Content

An eccentric wheel is fixedly connected to the inside of the motor. A spring is sleeved on the outer wall of the multiple limiting rods. Limiting rods are fixedly connected to the left and right sides. A disassembly assembly for quick disassembly is installed at the top of the vortex mixer.

[0008] As a further description of the above technical solution:

[0009] A square box two is fixedly connected to the top of the vortex mixer. A cylinder is fixedly connected to the inner wall of the square box two.

[0011] The top outer wall of the connecting rod is threaded with an elastic screw cap, the inner wall of the elastic screw cap is fixedly connected with an elastic column, the inner wall of the connecting rod is slidably connected with a centrifuge tube platform, both ends of the centrifuge tube platform are fixedly connected with centrifuge tube racks, the front ends of the two centrifuge tube racks are fixedly connected with elastic pressure caps, the inner wall of the elastic column is fixedly connected with a spring, and the bottom end of the vortex mixer is fixedly connected with a suction cup.

[0012] As a further description of the above technical solution:

[0013] The outer walls of the two limiting rods are slidably connected to the inner wall of the square box, and the bottom end is slidably connected to the inner wall of the square box.

[0014] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this invention, the motor inside the vortex mixer is activated, driving the eccentric wheel to rotate and generate an eccentric force, which in turn causes the fixed block to vibrate. The limiting rod slides within the square box, and the spring buffers and dampens the vibration. This vibration effect creates three-dimensional turbulence in the centrifuge tube through vortex motion, rapidly breaking down liquid stratification and particle sedimentation, significantly improving mixing uniformity. While ensuring sample activity, it shortens mixing time, reduces the risk of cross-contamination, and balances efficient mixing with experimental flexibility, providing stable and reliable sample pretreatment support for molecular biology, cell culture, and other scenarios.

[0024] 2. In this utility model, the starting cylinder pushes the sliding block to slide inside the square box two, causing the rotating transmission rod to swing. The transmission rod pushes the fixed block one to move along the limiting rod three, compressing the spring two and fixing the connecting rod. Different specifications of centrifuge tube clamps can be quickly replaced without tools. At the same time, it is easy to disassemble and clean the connecting rod separately to avoid sample residue contamination, simplify the equipment maintenance process, reduce downtime, and save space when transporting or storing. The anti-accidental locking structure ensures a stable connection during vibration. It not only improves the efficiency and flexibility of experimental operation, but also reduces the risk of cross-contamination and maintenance costs, and is suitable for high-throughput experiments and multi-scenario switching needs.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1 to 3 This utility model provides an embodiment of an adjustable vortex mixer centrifuge tube adapter, including a vortex mixer 1. A square box 2 is fixedly connected to the inner wall of the vortex mixer 1, providing a stable mounting base for the square box 2 and serving as a load-bearing frame for the internal transmission components. The square box 2 is fixed to the inner wall of the vortex mixer 1, protecting the core components such as the internal limiting rods 3 and the motor 5, while providing a closed and stable spatial environment for their operation. Multiple limiting rods 3 are slidably connected to the inner wall of the square box 2. The limiting rods 3 can slide back and forth inside, and the two work together to limit the movement direction of the fixed block 4, ensuring that the vibration energy generated by the eccentric wheel 6 driven by the motor 5 is transmitted along a preset trajectory, avoiding deviation during operation. Fixed blocks 4 are fixedly connected to the adjacent sides of the multiple limiting rods 3. The fixed blocks 4 are stably suspended by the limiting rods 3. Under the drive of the motor 5, vibration adjustment is achieved by sliding the limiting rods 3, while maintaining the compactness of the overall structure.

[0033] A motor 5 is fixedly connected inside the fixed block 4, providing a rigid mounting base for the motor 5 to ensure its stability during operation. An eccentric wheel 6 is fixedly connected to the drive end of the motor 5, which drives the eccentric wheel 6 to rotate at high speed. The centrifugal force generated by the offset of the center of gravity of the eccentric wheel 6 is used to convert the circular motion of the motor 5 into the reciprocating vibration of the fixed block 4, which is then transmitted to the centrifuge tube adapter to achieve vortex mixing of the sample in the centrifuge tube. Springs 7 are sleeved on the outer walls of multiple limiting rods 3. When the fixed block 4 is driven to vibrate by the eccentric wheel 6, the springs 7 absorb the impact force through compression or stretching, reducing the impact of vibration on the overall structure. Limiting rods 8 are fixedly connected to both the left and right sides of the fixed block 4 to prevent the fixed block 4 from shifting or shaking during vibration, ensuring that the vibration energy generated by the eccentric wheel 6 is accurately transmitted to the centrifuge tube adapter, improving mixing efficiency and accuracy. A disassembly assembly for quick disassembly is installed at the top of the vortex mixer 1. The disassembly assembly at the top of the vortex mixer 1 enables quick disassembly and assembly of the centrifuge tube adapter.

[0034] Reference Figures 2 to 4A square box 9 is fixedly connected to the top of the vortex mixer 1. The square box 9 provides an installation platform for the adjustment components such as the cylinder 10, making the square box 9 the core load-bearing structure for the centrifuge tube adapter direction adjustment. The cylinder 10 is fixedly connected to the inner wall of the square box 9, which securely integrates the cylinder 10 inside the equipment, protecting it from external interference. At the same time, it provides stable support for the extension and retraction movement of the cylinder 10's drive end, ensuring the stability of power output. A sliding block 11 is fixedly connected to the drive end of the cylinder 10. The drive end of the cylinder 10 is directly connected to the sliding block 11, controlling the sliding trajectory of the sliding block 11 within the square box 9, realizing the efficient transmission of power from the cylinder 10 to the subsequent transmission structure. Two transmission rods 12 are rotatably connected to the inner wall of the sliding block 11, converting the linear motion of the sliding block 11 into the oscillation of the transmission rods 12.

[0035] Both transmission rods 12 are rotatably connected to fixed blocks 13 on their outer walls. When the transmission rods 12 swing, they drive the fixed blocks 13 to slide along the limiting rods 14. Two limiting rods 14 are fixedly connected inside the square box 9. The two limiting rods 14 inside the square box 9 provide guidance and limitation for the sliding of the fixed blocks 13. Springs 15 are sleeved on the outer walls of the two limiting rods 14. The springs 15 play a buffering and shock-absorbing role when the fixed blocks 13 move, absorbing the impact force during the adjustment process. Connecting rods 16 are fixedly connected to the adjacent side of the two fixed blocks 13. The connecting rods 16 are fixedly connected to the adjacent side of the two fixed blocks 13. The connecting rods 16 are fixed by the synchronous movement of the fixed blocks 13.

[0036] Reference Figures 2 to 4 The top outer wall of the connecting rod 16 is threaded with a spring-loaded screw cap 17. The top of the connecting rod 16 is connected to the spring-loaded screw cap 17 via threads, achieving detachable fixing. A spring-loaded column 18 is fixedly connected to the inner wall of the spring-loaded screw cap 17. The spring-loaded column 18 fixed to the inner wall of the spring-loaded screw cap 17 serves as a buffer and pressure transmission component. A centrifuge tube platform 19 is slidably connected to the inner wall of the connecting rod 16. The centrifuge tube platform 19 slides on the inner wall of the connecting rod 16. The sliding connection method, combined with the pressure adjustment of the spring-loaded screw cap 17, enables the adjustment of different specifications. The centrifuge tubes are flexibly adapted and stably fixed. Centrifuge tube racks 20 are fixedly connected to both ends of the centrifuge tube carrier 19. The centrifuge tube racks 20 fixed to both ends of the centrifuge tube carrier 19 constitute the direct bearing structure of the centrifuge tubes. The stable connection method ensures that the centrifuge tubes remain vertical and stable during the vortex mixing process. The front ends of the two centrifuge tube racks 20 are fixedly connected to elastic pressure caps 21. The elastic pressure caps 21 at the front ends of the centrifuge tube racks 20 fit tightly against the top of the centrifuge tubes through elastic deformation, further enhancing the fixing effect of the centrifuge tubes.

[0037] A spring 22 is fixedly connected to the inner wall of the elastic column 18. The spring 22 is fixed to the inner wall of the elastic column 18 to ensure stable clamping of the centrifuge tube platform 19 and the centrifuge tubes, while also providing vibration damping. A suction cup 23 is fixedly connected to the bottom of the vortex mixer 1. The suction cup 23 at the bottom of the vortex mixer 1 adheres tightly to the workbench surface through vacuum adsorption, providing strong grip for equipment operation. When high-frequency vibrations are generated during vortex mixing, the suction cup 23 effectively prevents equipment displacement or sliding, ensuring operational safety and experimental stability. Two limiting rods 28... The outer wall is slidably connected to the inner wall of the square box 2. The limiting rod 8 slides on the inner wall of the square box 2, restricting the degree of freedom of movement of the fixed block 4, ensuring that the vibration generated by the motor 5 driving the eccentric wheel 6 is transmitted along a precise trajectory, and improving the consistency of the mixing effect. The bottom end of the fixed block 4 is slidably connected to the inner wall of the square box 2. The square box 2 provides sliding support and guidance for the fixed block 4. At the same time, the elastic connection of the spring 7 balances the impact force generated by the vibration and maintains the long-term stable operation of the equipment. One end of the spring 7 is fixedly connected to the outer wall of the fixed block 4.

[0038] The other end of spring 7 is fixedly connected to the outer wall of square box 2. Both ends of spring 7 are connected to fixed block 4 and square box 2 respectively, serving as a buffer, reset, and vibration damper. When fixed block 4 vibrates under the drive of eccentric wheel 6, spring 7 absorbs energy through compression and tension, mitigating the impact of vibration on the overall structure of the equipment and extending its service life. The outer wall of fixed block 13 is slidably connected to the inner wall of square box 9. Fixed block 13 slides on the inner wall of square box 9 and moves along the outer wall of limit rod 14. Double limit ensures the accuracy of its movement trajectory. The inner wall of fixed block 13 is slidably connected to the outer wall of limit rod 14. Square box 9 provides installation space and protection, while limit rod 14 prevents fixed block 13 from shifting, ensuring the reliability of centrifuge tube adapter direction adjustment. The outer wall of sliding block 11 slides... The sliding block 11 is connected to the inner wall of the square box 2 9. The square box 2 9 provides a stable sliding track for the sliding block 11, ensuring that the extension and retraction of the cylinder 10 can be accurately converted into the swing of the subsequent transmission rod 12. The two ends of the spring 2 15 are fixedly connected to the adjacent side of the two fixed blocks 2 13. The two ends of the spring 2 15 are connected to the two fixed blocks 2 13. During the adjustment of the centrifuge tube adapter direction, the spring 2 plays the role of buffering, resetting and balancing the tension. The inner wall of the square box 1 2 is provided with a sliding groove. The sliding groove provided in the inner wall of the square box 1 2 provides a precise motion guide track for the limit rod 1 3, the limit rod 2 8 and the fixed block 1 4. The outer wall of the connecting rod 16 slides on the inner wall of the square box 2 9. The inner wall of the square box 2 9 provides a sliding track for the connecting rod 16, so that the connecting rod 16 can move up and down or adjust the angle under the drive of the cylinder 10.

[0039] Working Principle: When the vortex mixer is started, the motor 5 inside the square box 2 begins to operate. Its drive end drives the eccentric wheel 6 to rotate. The centrifugal force generated by the rotation of the eccentric wheel 6 causes the fixed block 4 to reciprocate. When the fixed block 4 is under force, it drives the multiple limiting rods 3 fixed to it to slide on the inner wall of the square box 2. The springs 7 on the outer wall of the limiting rods 3 are compressed or stretched accordingly, buffering the impact force of the fixed block 4's movement through elastic deformation, ensuring smooth movement. At the same time, the limiting rods 8 on the left and right sides of the fixed block 4 further constrain the movement trajectory, preventing the fixed block 4 from shifting or shaking during the reciprocating motion. This reciprocating motion, driven by the motor 5 and converted by the eccentric wheel 6, is stably transmitted to the centrifuge tube adapter through the synergistic action of the limiting rods 3, springs 7, and limiting rods 8, realizing the vortex mixing of the sample in the centrifuge tube. The mixing intensity can be changed by adjusting the speed of the motor 5 to meet different experimental needs.

[0040] When it is necessary to fix or disassemble the connecting rod 16, the cylinder 10 starts working, and its drive end pushes the sliding block 11 to slide on the inner wall of the square box 9. When the sliding block 11 moves, it drives the two transmission rods 12 that rotate with its inner wall to swing. The transmission rods 12 convert the linear motion of the sliding block 11 into the translational motion of the fixed block 13 through the rotating connection point. The fixed block 13 slides along the limiting rod 14. During this process, the spring 15 sleeved on the outer wall of the limiting rod 14 plays a buffering and restoring role. When the fixed block 13 is moved by force, the spring 15 is compressed and accumulates elastic potential energy to reduce the impact force during the adjustment process; when the external force is removed, the spring 15 releases elastic potential energy to help the fixed block 13 stabilize its position. The two fixed blocks 13 move synchronously to fix or disassemble the connecting rod 16.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
