Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, and more specifically, to a centrifuge container. Background Art

[0002] As a commonly used biochemical experimental instrument in laboratories, centrifuge tubes are widely used in various experimental operations such as blood separation, cell culture, and sample preparation. Their design and performance directly affect the efficiency of experiments and the accuracy of results. With the continuous progress of science and technology and the increasing diversification of experimental requirements, higher requirements are put forward for the sealing performance, operation convenience, and physical stability of centrifuge tubes.

[0003] Currently, conventional centrifuge tubes on the market are mainly divided into two types according to the closing method of the upper cover: snap-on type and screw-cap type. Snap-on centrifuge tubes have been widely used in laboratories due to their simple operation, high cost-effectiveness, and excellent physical properties. The design of this type of centrifuge tube allows users to quickly open and close the lid with one hand, facilitating the rapid access to liquid samples during experiments.

[0004] However, the existing snap-on centrifuge tubes still have some defects in actual use. Although their original design is to improve the operation convenience, when storing liquids for a long time or conducting tests under different environmental conditions, the sealing performance of snap-on centrifuge tubes often fails to meet the high-standard experimental requirements. In some cases, due to poor sealing, the centrifuge tubes may leak during use, which not only affects the accuracy of the experiment but also may contaminate the experimental environment.

[0005] In addition, after multiple openings and closings of the snap-on centrifuge tube, the fit between the lid and the tube body may gradually become loose, further increasing the risk of leakage. This structural deficiency limits the application scenarios of snap-on centrifuge tubes that require long-term sealed storage or use in harsh environments.

[0006] In summary, although the existing snap-on centrifuge tubes have advantages in operation convenience and cost-effectiveness, their deficiencies in sealing performance and durability limit their application under more extensive and complex experimental conditions. Especially when long-term sealing or experiments under variable environmental conditions are required, these defects of the existing snap-on centrifuge tubes may become key factors in the success or failure of the experiment. Therefore, improving the design of the existing snap-on centrifuge tubes and enhancing their sealing performance and durability are of great significance for meeting the growing experimental requirements.

[0052] Reference Figure 1 , an embodiment of the present application provides a centrifuge container 100, including:

[0053] a tube body device 1, and an upper cover device 2 connected to the tube body device 1;

[0054] a receiving cavity 11 is provided in the tube body device 1;

[0055] the upper cover device 2 includes an upper cover mechanism 21, and a soft rubber structure 22 connected to the upper cover mechanism 21;

[0056] the soft rubber structure 22 can be placed into the receiving cavity 11, and the upper cover device 2 can be in interference fit with the receiving cavity 11 of the tube body device 1 through the soft rubber structure 22 in the upper cover mechanism 21.

[0057] As described above, the centrifuge container 100 provided in the embodiment of the present application can be a snap-on centrifuge tube for the biomedical field, which is used to place liquids or semi-fluid substances, and is a commonly used consumable in laboratories, mainly used for the collection, storage and processing of biological samples that require high-speed centrifugation. Conventional centrifuge tubes are designed with matching snap-on lids to ensure the safety of samples during centrifugation and prevent cross-contamination.

[0058] In the embodiment of the present application, the provided centrifuge container 100 includes two main parts, namely the tube body device 1 and the upper cover device 2. The tube body device 1 and the upper cover device 2 are connected, so that the upper cover device 2 can cover the upper opening of the tube body device 1 to achieve a sealing effect. Its overall shape refers toFigure 1 As shown, the structural reference when opening the upper cover device 2 Figure 2 .

[0059] As mentioned above, for reference Figure 3 , in the tube body device 1, there is a receiving cavity 11 for placing samples.

[0060] In the upper cover device 2, it includes an upper cover mechanism 21 and a soft rubber structure 22. Among them, the soft rubber structure 22 can be referred to Figure 4 , when the upper cover device 2 is closed on the tube body device 1, the soft rubber structure 22 of the upper cover device 2 can have an interference fit with the receiving cavity 11 of the tube body device 1, so that the tube body device 1 and the upper cover device 2 are sealed.

[0061] In short, for the centrifuge container 100 provided in this embodiment, through the interference fit between the soft rubber structure 22 in its upper cover device 2 and the receiving cavity 11 of the tube body device 1, excellent sealing performance is provided, effectively preventing liquid leakage during centrifugation, ensuring the safety and accuracy of the experiment. At the same time, this design simplifies the operation process, enabling users to open and close quickly and easily, improving the experimental efficiency. In addition, the elastic characteristics of the soft rubber structure 22 and the design of the interference fit not only enhance the durability of the container, reduce the decline in sealing performance caused by wear or aging, but also reduce the maintenance cost and extend the service life. The high sealing performance and durability of this centrifuge container 100 significantly reduce the pollution risk in the laboratory environment, providing a cleaner and safer working environment for the experiment.

[0062] Furthermore, the upper cover mechanism 21 includes an upper cover plate 211 and a protruding end 212 provided on the upper cover plate 211;

[0063] The protruding end 212 faces the direction of the receiving cavity 11 and can be placed in the receiving cavity 11.

[0064] As mentioned above, there is a protruding end 212 on the upper cover plate 211, and the protruding end 212 can be inserted into the receiving cavity 11.

[0065] Furthermore, the soft rubber structure 22 includes a connecting substrate 221 and an extending end 222 provided on the connecting substrate 221;

[0066] The connecting substrate 221 is attached to the side of the upper cover plate 211 facing the receiving cavity 11 and can abut against the upper opening of the tube body device 1 after closing;

[0067] The extending end 222 is sleeved on the protruding end 212.

[0068] As mentioned above, in the soft silicone rubber structure, the connecting substrate 221 and the extending section can be of the same material or different materials.

[0069] The soft silicone structure can be a component with certain elasticity. Among them, the connecting substrate 221 can be attached to the surface of the upper cover plate 211 facing the accommodating cavity 11. Its size can be the same as or similar to that of the upper cover plate 211. When the upper cover device 2 covers the upper opening of the tube device 1, the connecting substrate 221 can be attached to the upper opening of the tube device 1, thereby achieving abutment. During abutment, the connecting substrate 221 undergoes elastic deformation under the downward pressure, further improving the sealing effect.

[0070] As described above, the extension end 222 can be inserted into the upper opening of the tube device 1. Thus, when the upper cover device 2 is closed, the extension section is inserted into the upper opening of the tube device 1 and enters the accommodating cavity 11 to form an interference fit.

[0071] Furthermore, the soft rubber structure 22 is a soft rubber structure 22 with elasticity; and, the cross-sectional size of the protruding end 212 is not less than the size of the upper opening of the accommodating cavity 11.

[0072] As described above, the soft rubber structure 22 as a whole is a soft rubber structure 22 with elasticity. For example, it can include but is not limited to rubber, silicone, silicone rubber, and so on.

[0073] As described above, the cross-sectional size of the protruding end 212 is not less than the size of the upper opening of the accommodating cavity 11. Thus, when inserted into the accommodating cavity 11, it can undergo elastic deformation through elasticity to form an interference fit and achieve the sealing effect.

[0074] Furthermore, referring to Figure 5 , a first engaging structure 213 is provided at the front end of the protruding end 212;

[0075] The tube device 1 includes a tube body 12 and a second engaging structure 13 provided on the inner side wall of the tube body 12;

[0076] When the upper cover device 2 is covered on the tube device 1, the first engaging structure 213 can be engaged with the second engaging structure 13.

[0077] In order to further improve the tightness of the upper cover device 2 covering the tube device 1, a first engaging structure 213 is provided at the front end of the protruding end 212, that is, at one end of the protruding end 212 facing the tube device 1; on the inner side wall of the tube body 12 of the tube device 1, a second engaging structure 13 is provided; the first engaging structure 213 corresponds to the second engaging structure 13.

[0078] When the upper cover device 2 is closed, the first engaging structure 213 can be engaged with the second engaging structure 13, so that on the basis of the interference fit between the soft rubber structure 22 and the accommodating cavity 11 of the tube device 1, the upper cover device 2 and the tube device 1 form an engagement from the inside to form a lock, constituting a "second line of defense" to further improve the tightness.

[0079] Furthermore, the tube body 12 is an elastic tube body 12; and when the tube body 12 undergoes elastic deformation, the first engaging structure 213 and the second engaging structure 13 can be disengaged from each other.

[0080] It should be noted that the centrifuge container 100, that is, a snap-on centrifuge tube. Conventional snap-on centrifuge tubes are disposable centrifuge containers 100. Such consumables are small in volume, low in cost, and convenient to use. During operation, when opening the lid, it can be pushed open upward with the thumb by one hand to open the upper cover.

[0081] However, for existing snap-on centrifuge tubes, when dealing with a small number of samples, they have certain operational advantages. When dealing with a large number of samples, the repetitive labor of using disposable snap-on centrifuge tubes will cause fatigue in the operator's hands and increase the risk of tendinitis or other repetitive strain injuries. Although this one-handed operation is convenient, it may reduce work efficiency in the processing of a large number of samples because it takes time to open and close the lid each time. In addition, rapid operation may cause the lid to fail to close properly, resulting in an inability to achieve a tight seal, causing leakage, and affecting the centrifugation effect and sample safety. There is also a risk of cross-contamination if the lid is accidentally opened or fails to close properly during operation.

[0082] Therefore, in order to meet the requirements of high-capacity sample processing, this design needs to be further improved. In the embodiments of the present application, the tube body 12 is an elastic tube body 12 that can undergo a certain degree of elastic deformation. By operating with one hand or both hands, or by using an instrument, the tube body 12 of the centrifuge container 100 can be elastically deformed to a certain extent. At this time, the first engaging structure 213 and the second engaging structure 13 can be disengaged from each other, that is, unhooked, so as to end the "engaging" effect and separate the first engaging structure 213 and the second engaging structure 13, and then the upper cover device 2 and the tube device 1 can be separated, thus realizing a change from the existing method of pushing the upper cover upward with the thumb to opening the lid by squeezing the tube body 12 to cause elastic deformation of the tube body 12. On the one hand, it improves the convenience of one-handed operation and avoids mechanical damage and fatigue to the hands caused by conventional snap-on centrifuge tubes. On the other hand, it avoids the risk of leakage caused by the inability to achieve a tight seal in the conventional operation method.

[0083] Furthermore, the protruding end 212 is a hollow tubular structure, and a clamping concave cavity 2121 is provided therein;

[0084] The first engaging structure 213 includes a horizontally extending boss 2131 disposed in the engaging cavity 2121 of the protruding end 212, and a fixing protrusion 2132 disposed on the extending boss 2131; the inner side surface of the fixing protrusion 2132 is an arcuate first arcuate surface 21321;

[0085] The second engaging structure 13 includes an extending portion 131 extending from the inner side wall of the tube body 12 towards the center, and an inwardly bent portion 132 connected to the extending portion 131; one end of the inwardly bent portion 132 facing the first arcuate surface 21321 of the fixing protrusion 2132 is provided with a second arcuate surface 1321 corresponding to the first arcuate surface 21321;

[0086] When the upper cover device 2 is closed on the tube device 1, the inwardly bent portion 132 can be snapped onto the fixing protrusion 2132 from within the engaging cavity 2121, and the first arcuate surface 21321 abuts against the second arcuate surface 1321.

[0087] The above is an improvement designed for the centrifuge container 100, specifically providing the technical feature that the upper cover device 2 and the tube device 1 are tightly connected through the engaging structure.

[0088] As described above, the protruding end 212 of the upper cover device 2 is designed as a hollow tube, and this design allows an engaging cavity 2121 to be formed inside the protruding end 212 for accommodating and fixing the engaging structure.

[0089] Inside the engaging cavity 2121 of the protruding end 212, there is a horizontally extending boss, which is part of the first engaging structure 213 and plays a key role when the upper cover device 2 is closed. The extending direction of the extending boss 2131 is perpendicular to the length direction of the protruding end 212, that is, it is disposed perpendicular to the inner side wall of the engaging cavity 2121 of the protruding end 212.

[0090] On the extending boss 2131, there is also a fixing protrusion 2132; for the fixing protrusion 2132 to smoothly complete the opening operation, the shapes of the inner and outer side surfaces are different, and the inner side is the arcuate first arcuate surface 21321. In addition, its outer side can be a vertical plane.

[0091] The tube device 1 includes a tube body 12, and a second engaging structure 13 is provided on its inner side wall. This second engaging structure 13 consists of two parts: one is an extending portion 131 extending from the inner side wall of the tube body 12 towards the center, and the other is an inwardly bent portion 132 connected to the extending portion 131.

[0092] Among them, one end of the inner bent portion 132 facing the first arc surface 21321 of the fixed protrusion 2132 is provided with a second arc surface 1321 corresponding to the first arc surface 21321.

[0093] Regarding the clamping mechanism, it can be the following two situations:

[0094] (1) When the upper cover device 2 is closed on the tube body device 1, the horizontally extending convex platform 2131 of the first clamping structure 213 will interact with the inner bent portion 132 of the second clamping structure 13. At this time, the inner bent portion 132 is connected to the horizontally extending convex platform 2131 to form an internal "hook connection" form, and the first arc surface 21321 abuts against the second arc surface 1321;

[0095] (2) When the tube body 12 undergoes elastic deformation under an external force, the inner bent portion 132 moves towards the center direction of the tube body 12, the second arc surface 1321 passes through the first arc surface 21321 and continues to move towards the center direction, so that the inner bent portion 132 and the horizontally extending convex platform 2131 end the "clamping" state. At this time, the upper cover device 2 can be opened.

[0096] As described above, the shapes of the two sides of the fixed protrusion 2132 are different. Its inner side is the first arc surface 21321, and the outer side is a vertical surface. At the same time, the second arc surface 1321 of the inner bent portion 132 is matched with it. When the first arc surface 21321 and the second arc surface 1321 are in contact and it is necessary to disconnect the "hook connection" form, the contact between the two arc surfaces can smoothly release the "clamping" state.

[0097] Specifically, the inner bent portion 132 can extend out of the clamping cavity 2121 and engage with the horizontally extending convex platform 2131 to form a stable clamping.

[0098] Through this design, a firm connection is formed between the upper cover device 2 and the tube body device 1, which can remain stable even during high-speed centrifugation, prevent the lid from accidentally opening, and thus ensure the safety of the sample and prevent cross-contamination.

[0099] Since the tube body 12 is elastic, when it is necessary to open the lid, the first clamping structure 213 can be disengaged from the second clamping structure 13 by elastically deforming the tube body 12, so as to conveniently open the upper cover.

[0100] The specific structural design improves the sealing performance and operation convenience of the centrifuge container 100, and also increases the stability and safety of the container during centrifugation.

[0101] In addition, in the first clamping structure 213, a third arc surface 21311 is provided at the end of the horizontally extending convex platform 2131 away from the protruding end;

[0102] In the second engaging structure 13, at one end of the inner bent portion 132 facing away from the first arc surface 21321 of the fixed protrusion 2132, a fourth arc surface 1322 corresponding to the third arc surface 21311 is provided.

[0103] When the upper cover device 2 needs to be closed on the tube body device 1, the upper cover device 2 is pressed downward. First, the third arc surface 21311 will abut against the fourth arc surface 1322. Since both surfaces are arc surfaces, it will continue to move through the arc surfaces, forming a state where the inner bent portion 132 is buckled on the fixed protrusion 2132 from the clamping cavity 2121, so that the first arc surface 21321 abuts against the second arc surface 1321, improving the convenience when the upper cover device 2 is closed and enabling it to smoothly reach the sealed state.

[0104] Further, referring to Figure 6 , the tube body 12 includes two symmetrically arranged support portions 122 and two symmetrically arranged elastic portions 121; the support portions 122 and the elastic portions 121 are connected in sequence to form the tube body 12; the elastic portion 121 includes a longitudinal first ergonomic groove 1211 and a transverse second ergonomic groove 1212;

[0105] The second ergonomic groove 1212 intersects and is perpendicular to the first ergonomic groove 1211;

[0106] The second engaging structure 13 is provided on the inner side wall of the support portion 122;

[0107] The support portion 122 can cause the elastic portion 121 to generate elastic deformation by an external force, so that the second engaging structure 13 in the support portion 122 is disengaged from the first engaging structure 213.

[0108] As described above, this part details the structural design of the tube body 12 of the centrifuge container 100, increasing the ergonomic characteristics to improve the convenience and comfort of operation.

[0109] The tube body 12 is composed of two symmetrically arranged support portions 122 and two symmetrically arranged elastic portions 121. This symmetric design helps to maintain the balance and stability of the container.

[0110] The support portion 122 and the elastic portion 121 are connected in sequence to form the structure of the tube body 12. The support portion 122 provides the main supporting force of the container, while the elastic portion 121 allows the container to undergo elastic deformation when needed.

[0111] The elastic part 121 includes a longitudinal first ergonomic groove 1211 and a transverse second ergonomic groove 1212. The design of these grooves is aimed at improving the holding comfort and stability of the user during operation.

[0112] The second ergonomic groove 1212 intersects and is perpendicular to the first ergonomic groove 1211. This design may further enhance the stability and comfort during holding, making the user feel better during operation and reducing hand fatigue.

[0113] As mentioned above, the width of the first ergonomic groove 1211 in the horizontal direction can be the same as the width of the second ergonomic groove 1212 in the longitudinal direction, or can be slightly larger than the width of the second ergonomic groove 1212 in the longitudinal direction. In a preferred embodiment, the width of the first ergonomic groove 1211 in the horizontal direction is greater than the width of the second ergonomic groove 1212 in the longitudinal direction.

[0114] Among them, the first ergonomic groove 1211 can correspond to the width of the thumb, and the width of the second ergonomic groove 1212 in the longitudinal direction can correspond to the width of the index finger. Since the tube body 12 is composed of two symmetrically arranged support parts 122 and two symmetrically arranged elastic parts 121, and the elastic part 121 includes a longitudinal first ergonomic groove 1211 and a transverse second ergonomic groove 1212. When holding, such as holding with one hand, the thumb can be placed in the first ergonomic groove 1211 of the first elastic part 121, and the index finger can be placed in the second ergonomic groove 1212 of the other elastic part 121 on the opposite side, so as to realize the holding of the centrifuge container 100, and the tube body 12 can be further squeezed by the thumb and the index finger to perform the operation of opening the lid, further improving the convenience.

[0115] The second engaging structure 13 is provided on the inner side wall of the support part 122, which enables the lid to be opened by applying an external force to the support part 122 when needed.

[0116] The support part 122 can cause the elastic part 121 to produce elastic deformation by an external force, so that the second engaging structure 13 is disengaged from the first engaging structure 213. This design allows the user to manually open the lid without using tools, improving the convenience of operation.

[0117] Through these design features, the centrifuge container 100 can achieve the following effects:

[0118] Improve operation comfort: The design of the ergonomic grooves makes the user's hand more comfortable during long-term operation and reduces fatigue.

[0119] Enhance stability: The symmetric design and the cross-perpendicular layout of the grooves improve the stability of the container.

[0120] Simplify the lid-opening process: The user can manually open the lid through elastic deformation without additional tools, improving the convenience of operation.

[0121] Maintain airtightness: In the closed state of the lid, the tight fit between the second engaging structure 13 and the first engaging structure 213 ensures the airtightness of the container.

[0122] Solve problems: This design solves the problems of hand fatigue, inconvenient lid-opening, and insufficient airtightness that may occur in traditional centrifuge containers 100 during the processing of a large number of samples.

[0123] In summary, by introducing ergonomic design and elastic deformation mechanism, the usage experience and operation efficiency of the centrifuge container 100 are improved, while maintaining the airtightness and stability of the container.

[0124] Furthermore, the centrifuge container 100 further includes a connecting device 3;

[0125] The tube body device 1 is connected to the upper lid device 2 through the connecting device 3;

[0126] The connecting device 3 includes a flexible connecting member 31 and an elastic member 32 connected to the flexible connecting member 31;

[0127] When the second engaging structure 13 in the supporting portion 122 disengages from the first engaging structure 213, the elastic member 32 can eject the upper lid device 2 and the tube body device 1 so that the upper lid device 2 moves away from the tube body device 1.

[0128] The above is the connecting device 3 in the centrifuge container 100, which allows for a more convenient and safe connection and separation mechanism between the upper lid device 2 and the tube body device 1.

[0129] The centrifuge container 100 includes a connecting device 3 for connecting the tube body device 1 and the upper lid device 2. The connecting device 3 consists of a flexible connecting member 31 and an elastic member 32 connected thereto. This design allows the connecting device 3 to bend or deform to a certain extent to adapt to different operation requirements.

[0130] When the supporting portion 122 causes the elastic portion 121 to generate elastic deformation through an external force, resulting in the second engaging structure 13 disengaging from the first engaging structure 213, the role of the elastic member 32 becomes important.

[0131] The elastic member 32 can eject the upper lid device 2 and the tube body device 1 when the second engaging structure 13 disengages from the first engaging structure 213. This ejection mechanism allows the upper lid device 2 to easily move away from the tube body device 1.

[0132] The elastic member 32 can be a leaf spring or a spring structure.

[0133] The ejection mechanism simplifies the process of opening the upper cover, allowing users to access the interior of the container more quickly, especially when multiple samples need to be processed rapidly. Since the upper cover device 2 can be ejected, it reduces the potential contamination or harm to the samples or users during the opening process. By reducing the need for manual operation, this design helps reduce hand fatigue that may be caused by long-term operation.

[0134] The problem to be solved is that traditional centrifuge containers 100 may require a large amount of force or specific tools to open, while this design makes the lid-opening process easier through the ejection mechanism of the elastic member 32. The introduction of the flexible connecting member 31 and the elastic member 32 improves the user experience when operating the centrifuge container 100, especially in application scenarios where the lid needs to be opened and closed frequently. The ejection mechanism can prevent accidental injuries to users that may be caused by the sudden opening of the lid during the lid-opening process.

[0135] In summary, by introducing the connecting device 3, especially the flexible connecting member 31 and the elastic member 32, a more user-friendly and safe opening and closing mechanism is provided for the centrifuge container 100, solving the problems of inconvenient operation and safety that may exist in traditional designs.

[0136] Furthermore, referring to Figure 7 , the tube body device 1 further includes a bracket structure 14 provided on the outer side wall of the tube body 12; and, a hidden groove 15 corresponding to the bracket structure 14 is provided on the outer side wall of the tube body 12;

[0137] The bracket structure 14 is hinged to the tube body 12 and can be placed into the hidden groove 15.

[0138] It should be noted that for conventional centrifuge tubes, due to their upper-wide and lower-narrow structure, when placing them, they need to be placed in a dedicated centrifuge tube test tube rack or a dedicated bracket equipment to achieve stable placement. Otherwise, if there is no such equipment, they can only be placed horizontally, which is extremely likely to contaminate the bottle cap with the liquid inside and cause contamination when opening the lid.

[0139] To solve the above problems, in the embodiments of the present application, in order to enable the centrifuge container 100 to be independently fixed, a bracket structure 14 is added on the basis of the above-mentioned centrifuge container 100 structure, and the tube body device 1 is further designed, specifically including:

[0140] The tube body device 1 is provided with a bracket structure 14 on the outer side wall of the tube body 12. This bracket structure 14 may be used to provide additional support or stability. The number of the bracket structures 14 may be one or more. For example, it may be 3. From a top view angle, one set may be arranged at every 60° angle. When support is needed, opening two adjacent sets can provide stable support.

[0141] A hidden groove 15 corresponding to the bracket structure 14 is provided on the outer side wall of the tube body 12. This means that when the bracket structure 14 is not in use, it can be received into the hidden groove 15. On the one hand, centrifugal operation can be carried out after being received. On the other hand, the appearance of the container can also be kept tidy.

[0142] The bracket structure 14 is hinged to the tube body 12, allowing the bracket structure 14 to rotate or move around the hinge point, so that it can be deployed or retracted as needed.

[0143] The bracket structure 14 can be placed into the hidden groove 15, providing a storage mechanism, enabling the bracket structure 14 to be neatly stored when not in use, reducing the occupied space, avoiding accidental collision or damage, and at the same time not affecting the centrifugal effect.

[0144] In the embodiment of the present application, a bracket structure 14 that can be deployed or retracted as needed is provided. The bracket structure 14 can be received into the hidden groove 15 to keep the container tidy and compact. Allowing a certain range of movement between the bracket structure 14 and the tube body 12 increases the flexibility of use.

[0145] Through this bracket structure 14, the following effects are achieved:

[0146] Improve stability: The bracket structure 14 may increase the stability of the container when deployed, especially when it needs to be used on an unstable surface.

[0147] Optimize space utilization: The storage design of the bracket structure 14 optimizes space utilization, making the container more compact when the bracket is not in use.

[0148] Enhance safety: The hinged and hidden storage design of the bracket structure 14 reduces the accidental injury or damage that may be caused when not in use.

[0149] In summary, by introducing the bracket structure 14 and the hidden groove 15, and adopting the hinge mechanism, a support system that can be deployed or retracted as needed is provided for the centrifuge container 100, solving the problems of stability, space occupation and safety that may exist in the traditional design.
