Description

Technical Field

[0001] This utility model relates to the field of syringe centrifugation technology, specifically to a centrifuge rotor for fixing centrifuge containers. Background Technology

[0002] Currently, centrifuges on the market have many problems when centrifuging with specialized syringes. Traditional centrifuges have a relatively generic overall structure design, lacking consideration for compatibility with specialized syringe rotors and adapters. This often leads to inaccurate positioning and poor stability when installing and using specialized components. Furthermore, the insufficient coordination between the drive and control systems of traditional centrifuges and specialized components results in low centrifugation efficiency, failing to meet the requirements for high-precision centrifugation of samples within specialized syringes. Specifically: Most existing centrifuge rotors are designed for general-purpose containers. When centrifuging specialized syringes, the shape and size of the syringes differ from those of the general-purpose containers, making it difficult for existing rotors to properly fit the syringes. This leads to the syringes easily shaking, tilting, or even falling off during centrifugation. Therefore, when the driver provides centrifugal force and rotates the centrifuge container to achieve centrifugation, the rotor, connected to and rotating synchronously with the container, suffers from poor precision and stability in its fit between the rotor and the container, affecting the stability, reliability, and safety of the centrifugation process. Furthermore, the existing rotor structure is simple and does not securely fix the syringe, failing to meet the requirements of high-precision centrifugation.

[0003] It is evident that the current centrifuge structure still has room for improvement and should be optimized to enhance its compatibility with the fixed fitting of centrifuge containers, ensuring stability and reliability during centrifugation operations and improving the precision and safety of centrifugation processing. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0004] In response to some of the problems existing in the prior art, this utility model discloses a centrifuge rotor for fixing centrifuge containers. By adjusting the rotor structure of the centrifuge, the centrifuge containers can be fixed more stably and reliably, maintaining precise positioning during centrifugation, improving stability, and ensuring the efficiency and safety of centrifugation.

[0005] To achieve the above objectives, the centrifuge rotor disclosed in this utility model can adopt the following scheme: A centrifuge rotor for fixing centrifuge containers includes a disc-shaped rotor body with several connecting slots evenly spaced along the circumference of the rotor body for accommodating centrifuge containers. A detachable centrifuge container is provided at the connecting slot, and the container of the substance to be centrifuged is placed inside the centrifuge container through a corresponding adapter.

[0006] The centrifuge rotor disclosed above cooperates with the centrifuge drive inside the centrifuge and rotates coaxially with the drive shaft. The centrifuge container fixed by the connecting groove formed on the rotor body can ensure the stability of the material to be centrifuged inside. The adapter inside the centrifuge container is replaceable and can be adapted to different material containers, thereby improving the compatibility with various material containers and ensuring the stability and reliability of the centrifugation process.

[0007] Furthermore, the rotor body can be constructed in various forms, and its structure is not limited to a single one. Here, we optimize and propose one feasible option: the rotor body is disc-shaped, and the connecting groove extends radially from the circumferential edge of the rotor body towards the center of the rotor body. Abutment structures are provided on both side walls of the connecting groove to cooperate in fixing the centrifuge container. With the above solution, the edge of the rotor body has a certain thickness, which facilitates the installation of the abutment structures.

[0008] Furthermore, the clamping structure can adopt various schemes and is not limited to one. Here, we optimize and propose one feasible option: the clamping structure includes an adjustment hole at least provided on one side wall of the connecting groove, and a clamping adjustment member provided in the adjustment hole. The clamping adjustment member and the adjustment hole are engaged by a snap ring and the centrifuge container is fixed in position along the adjustment hole. When adopting the above scheme, the adjustment hole extends from the edge of the rotor body toward the inner side wall of the connecting groove and penetrates into the connecting groove. Specifically, the connecting groove is arranged radially with parallel side walls, and the adjustment hole is perpendicular to the side wall of the connecting groove.

[0009] Furthermore, the centrifuge container, when containing materials to be centrifuged, allows for convenient placement and removal of the materials. Its structure is not uniquely limited; an optimization is proposed, and one feasible option is suggested: the centrifuge container includes a hanging body and a lid. The lid is detachably mounted on the hanging body, and the lid and hanging body form a receiving cavity. A replaceable adapter is installed within the receiving cavity to secure the material container. With this solution, the lid and hanging body can be connected by threads and a sealing ring is provided. The adapter within the receiving cavity corresponds to either the upright or inverted position of the material container, satisfying the need for securing the container under different placement methods, thereby improving the convenience and reliability of centrifugation.

[0010] Furthermore, the centrifuge container and the rotor body can be fitted in various ways. Here, we optimize the process and propose one feasible option: the hanging body is embedded in the connecting groove and fixed by a clamping structure. When using the above solution, the diameter of the hanging body is slightly smaller than the width of the connecting groove, and the clamping structure can achieve clamping by fixing it with a snap ring.

[0011] Furthermore, the connection between the rotor body and the drive shaft can be achieved in various ways. Here, we optimize the connection and propose one feasible option: the rotor body has a shaft hole for connecting and engaging the drive shaft. The shaft hole includes a tapered guide section and a straight hole section arranged sequentially from bottom to top. Using this scheme, the drive shaft passes through the tapered guide section and the straight hole section sequentially, allowing it to smoothly engage with the shaft hole. Simultaneously, a keyway corresponding to the drive shaft is provided within the shaft hole. After the rotor body and the drive shaft are engaged, a key is provided in the keyway to maintain the synchronicity of circumferential rotation.

[0012] Furthermore, during centrifugation, the movement of the rotor body can be monitored to obtain its real-time status. Here, an optimization is proposed, and one feasible option is suggested: a rotor identification component is coaxially mounted on the rotor body. This component rotates synchronously with the rotor body to monitor its rotational parameters. In this scheme, a fixed identification component is also mounted on the outside of the shaft. This fixed component is positioned opposite the rotor identification component and monitors synchronously to obtain parameters such as the rotor body's rotational speed, number of rotations, and time. Specifically, a sensor array can be used for monitoring. The data monitored by the sensor array is sent to a processor, which processes the data to obtain the monitoring results.

[0013] Furthermore, appropriately reducing the weight of the rotor body during rotation can help maintain stable operation and reduce drive energy consumption. Here, an optimization is proposed, and one feasible option is to form several sinking weight-reducing recesses on the rotor body. These recesses are evenly arranged along the circumference of the rotor body and correspond one-to-one with the connecting slots. In this scheme, the sinking weight-reducing recesses are constructed as a fan-shaped structure.

[0014] Furthermore, even after weight reduction, the strength of the rotor body still needs to be guaranteed. Here, we optimize and propose one feasible option: reinforcing ribs are formed between adjacent sinking weight reduction depressions. The number of reinforcing ribs is equal to the number of connecting grooves and they are evenly spaced along the circumference.

[0015] Furthermore, to ensure the stability of the material container, an adapter is used for auxiliary fixation. The structure is not uniquely limited; an optimization is proposed here, suggesting one feasible option: the adapter is placed inside the centrifuge container and fits tightly against the inner wall of the centrifuge container, with a fitting groove formed on the adapter for placing the material container. When using the above scheme, the outer wall surface of the adapter forms several protruding rings that fit against the inner wall surface of the centrifuge container.

[0016] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include: Improvements to the rotor body structure enhance the reliability of fixing the centrifuge container. The material container can be stably placed inside the centrifuge container via an adapter. By using an adapter that matches the material container, compatibility with various material containers can be achieved, thereby improving the stability and reliability of the centrifugation process.

[0024] The following description, in conjunction with the accompanying drawings and specific embodiments, further illustrates this embodiment.

[0025] In view of the poor compatibility of the rotor structure of existing centrifuges, which makes it difficult to fix the material containers with specific structures well when centrifuging, making it difficult to ensure the stability and reliability of the centrifugation process, and cannot accommodate centrifugation operations in various postures, thus affecting the centrifugation effect, the following embodiments are optimized to overcome the defects of the existing technology.

[0026] Example like Figures 1-5 As shown, this embodiment provides a centrifuge rotor for fixing centrifuge containers, including a disc-shaped rotor body 1. The rotor body 1 is provided with a plurality of connecting grooves 7 evenly spaced along the circumference to cooperate with centrifuge containers 2. A detachable centrifuge container 2 is provided at the connecting groove 7. The material container 9 to be centrifuged is placed in the centrifuge container 2 through the corresponding adapter 8.

[0027] The centrifuge rotor disclosed in this embodiment cooperates with the centrifuge drive inside the centrifuge and rotates coaxially with the drive shaft 12. The centrifuge container 2 fixed by the connecting groove 7 formed on the rotor body 1 can ensure the stability of the material to be centrifuged inside. The adapter 8 inside the centrifuge container 2 is replaceable and can be adapted to different material containers 9, thereby improving the compatibility with various material containers 9 and ensuring the stability and reliability of the centrifugation process.

[0028] The rotor body 1 can be constructed in various forms, and its structure is not uniquely limited. This embodiment optimizes and adopts one of the feasible options: such as Figure 1 , Figure 3 As shown, the rotor body 1 is disc-shaped, and the connecting groove 7 extends radially from the circumferential edge of the rotor body 1 towards the center of the rotor body 1. An abutment structure is provided on both side walls of the connecting groove 7 to cooperate in fixing the centrifuge container 2. With the above solution, the edge of the rotor body 1 has a certain thickness, which facilitates the installation of the abutment structure.

[0029] The clamping structure can adopt various solutions and is not limited to one. This embodiment optimizes and adopts one of the feasible options: such as Figure 2 As shown, the clamping structure includes an adjustment hole 5 at least on one side wall of the connecting groove 7, and a clamping adjustment member 6 disposed within the adjustment hole 5. The clamping adjustment member 6 engages with the adjustment hole 5 via a snap ring and fixes the centrifuge container 2 in position along the adjustment hole 5. In this configuration, the adjustment hole 5 extends from the edge of the rotor body 1 toward the inner wall of the connecting groove 7 and penetrates into the connecting groove 7. Specifically, the connecting groove 7 is radially arranged with parallel side walls, and the adjustment hole 5 is perpendicular to the side wall of the connecting groove 7.

[0030] The centrifuge container 2, when containing materials to be centrifuged, allows for convenient placement and removal of materials. Its structure is not uniquely limited; this embodiment optimizes the process and employs one feasible option: such as... Figure 2 , Figure 4 and Figure 5 As shown, the centrifuge container 2 includes a hanging body 202 and a cover 201. The cover 201 is detachably mounted on the hanging body 202, and the cover 201 and the hanging body 202 form a receiving cavity. A detachable and replaceable adapter 8 is installed in the receiving cavity to fix the material container 9. With the above solution, the cover 201 and the hanging body 202 can be connected by threads and a sealing ring is provided. The adapter 8 in the receiving cavity corresponds to the material container 9 being upright or inverted, satisfying the need for fixing the material container 9 under different placement methods, thereby improving the convenience and reliability of centrifugation.

[0031] Preferably, a clamping platform 203 is formed on the hanging body 202, and the clamping platform 203 cooperates with the clamping structure to realize the connection and fixation of the centrifuge container 2.

[0032] The centrifuge container 2 and the rotor body 1 can be fitted in various ways. This embodiment optimizes the process and adopts one feasible option: the hanging body 202 is embedded in the connecting groove 7 and fixed by a clamping structure. When the above solution is adopted, the diameter of the hanging body 202 is slightly smaller than the width of the connecting groove 7, and the clamping structure can achieve clamping after being fixed by a retaining spring.

[0033] The rotor body 1 and the drive shaft 12 can be connected in various ways. This embodiment optimizes the connection and adopts one feasible option: a shaft hole is formed on the rotor body 1 to connect and engage the drive shaft 12. The shaft hole includes a tapered guide section 13 and a straight hole section 14 arranged sequentially from bottom to top. When the above scheme is adopted, the drive shaft 12 passes through the tapered guide section 13 and the straight hole section 14 in sequence and can smoothly abut and engage with the shaft hole. At the same time, a keyway corresponding to the drive shaft 12 is also provided in the shaft hole. When the rotor body 1 and the drive shaft 12 are engaged, a key is provided in the keyway to maintain the synchronicity of circumferential rotation.

[0034] During centrifugation, the movement of rotor body 1 can be monitored to obtain its real-time status. This embodiment optimizes the process and adopts one feasible option: such as... Figure 4 , Figure 5As shown, a rotor identification component 10 is coaxially mounted on the rotor body 1. The rotor identification component 10 rotates synchronously with the rotor body 1 and is used to monitor the rotation parameters of the rotor body 1. In this scheme, a fixed identification component 11 is also provided on the outside of the shaft. The fixed identification component 11 is positioned opposite to the rotor identification component 10 and performs synchronous monitoring to obtain parameters such as the rotation speed, number of rotations, and time of the rotor body 1. Specifically, a sensor group can be used for monitoring. The data monitored by the sensor group is sent to a processor, which processes the data to obtain the monitoring results.

[0035] Reducing the weight of rotor body 1 during rotation helps maintain stable operation and reduces drive energy consumption. This embodiment optimizes this by adopting one feasible option: such as... Figure 1 As shown, a plurality of sinking weight-reducing recesses 3 are formed on the rotor body 1. The sinking weight-reducing recesses 3 are evenly arranged along the circumference of the rotor body 1 and correspond one-to-one with the connecting grooves 7. When the above scheme is adopted, the sinking weight-reducing recesses 3 are constructed as a fan-shaped structure.

[0036] Even after weight reduction, the strength of the rotor body 1 still needs to be maintained. This embodiment optimizes the design and adopts one feasible option: such as... Figure 1 , Figure 3 As shown, reinforcing ribs 4 are formed between adjacent sinking and weight-reducing depressions 3. The number of reinforcing ribs 4 is equal to the number of connecting grooves 7 and they are evenly spaced along the circumference.

[0037] To ensure the stability of the material container 9, an adapter 8 is used for auxiliary fixation. Its structure is not uniquely limited; this embodiment optimizes the process and adopts one feasible option: such as... Figure 4 , Figure 5 As shown, the adapter 8 is disposed inside the centrifuge container 2 and fits tightly against the inner wall of the centrifuge container 2. An adapter groove for placing the material container 9 is formed on the adapter 8. When the above scheme is adopted, several protruding rings are formed on the outer wall surface of the adapter 8 to fit against the inner wall surface of the centrifuge container 2.

[0038] Preferably, in this embodiment, the substance container 9 can be a syringe. When the syringe is placed upright in the adapter 8, the injection end of the syringe faces downward, and the bottom of the adapter 8 forms a groove 801 that corresponds to and matches the injection end. When the syringe is placed upside down in the adapter 8, the injection end of the syringe faces upward, and the bottom of the adapter 8 has a flat bottom structure that fits against the bottom of the syringe.

The above specific embodiments should not be construed as limiting the scope of protection of this example; the scope of protection of this example should be determined by the claims.
