When the existing oscillating instruments are in use, they generally need to be powered on, and the oscillation intensity can be adjusted, but the maximum intensity cannot meet the requirement of resuspending the precipitate at the bottom of the conical centrifuge tube after high-speed centrifugation. Therefore, there is an urgent need to design an oscillating device that can resuspend the precipitate at the bottom of the conical centrifuge tube. Utility Model Content

The size of the oscillation bars along the first direction gradually increases from the side away from the top surface to the side close to the top surface. An oscillation groove is formed between adjacent oscillation bars, and the first direction is parallel to the length direction of the chassis; and

[0006] A bracket, which is located above the chassis. A plurality of tube holes are formed in the bracket along a second direction, and the tube holes are used for inserting and fixing conical centrifuge tubes. The second direction is perpendicular to the first direction;

[0007] The conical centrifuge tube includes a centrifuge tube main body and a centrifuge tube cover body. The aperture of the tube hole is larger than the radial dimension of the centrifuge tube main body but smaller than the radial dimension of the centrifuge tube cover body; when the conical centrifuge tube is inserted and fixed on the tube hole, a part of the conical tube structure in the centrifuge tube main body is placed in the oscillation groove. At this time, when the bracket is moved along the first direction, the bracket can oscillate the conical centrifuge tube on it.

[0008] In one embodiment, the aperture of the tube hole is 1 mm - 2 mm larger than the radial dimension of the centrifuge tube main body.

[0009] In one embodiment, the thickness of the bracket is 1 cm - 1.5 cm.

[0010] In one embodiment, it further includes a guiding structure, and the bracket and the chassis are connected through the guiding structure. The guiding structure is used to play a guiding role when the bracket moves along the first direction.

[0011] In one embodiment, the bracket includes a main bracket board and two bracket side plates, and the two bracket side plates are respectively located at two ends of the main bracket board; the guiding structure includes an auxiliary mounting member, a roller and a guide rail; a guiding groove is formed on the chassis, and the bracket side plates, the guiding structure and the guiding groove are arranged in one-to-one correspondence; one end of the bracket side plate is connected to the main bracket board, the other end of the bracket side plate is connected to the auxiliary mounting member, the roller is rotatably fixed to the auxiliary mounting member, the guide rail is fixed to the guiding groove, and the roller is in rolling contact with the guide rail.

[0012] In one embodiment, the auxiliary mounting member includes a first mounting plate and two second mounting plates. One side of the first mounting plate is connected to the bracket side plate, and the other opposite side of the first mounting plate is respectively connected to one ends of the two second mounting plates. The roller is connected to the other ends of the two second mounting plates through a rotating shaft.

[0013] In one embodiment, a plurality of the brackets are configured. Along the first direction, a splicing convex block is provided on one side surface of the bracket, and a splicing groove corresponding to the position of the splicing convex block is formed on the other side surface of the bracket. The splicing convex block and the splicing groove between adjacent brackets are in concave-convex fit to realize detachable connection between adjacent brackets.

[0014] In one embodiment, the centrifuge tube cover is a pressing cover, and the centrifuge tube shaking device further includes a protective frame; the protective frame is provided with a plurality of protective grooves along the second direction, and the protective grooves and the tube holes are arranged in one-to-one correspondence. The protective grooves are adapted to the outer shape of the centrifuge tube cover so that the centrifuge tube cover can be placed in the protective grooves; the protective frame is used to be fixed on the bracket to play a role in fixing the centrifuge tube cover on the bracket.

[0015] In one embodiment, the protective frame is rotatably connected to the bracket through a connecting member, and the connecting member is a torsion spring or a hinge.

The conical tube of the conical centrifuge tube sequentially passes through different shaking grooves as the bracket moves. During this process, the conical tube in the conical centrifuge tube is successively applied with varying forces by multiple shaking bars and multiple shaking grooves formed by the multiple shaking bars, enabling the sediment in the conical tube of the conical centrifuge tube to be resuspended. The designed bracket is provided with multiple tube holes along the second direction, and correspondingly, multiple conical centrifuge tubes can be placed.

During the use of the centrifuge tube shaking device, there is no need to plug in the power. With only one hand, the bracket can be moved back and forth or unidirectionally on the chassis, breaking free from the geographical limitations of wire operations and making it more convenient to use.

Similar elements in different implementation manners are denoted by related similar reference numerals.

[0031] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in a manner obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean that they are the necessary sequences, unless it is stated that a certain sequence must be followed.

[0032] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. The "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0033] As Figures 1 - 11As shown in the figure, in an embodiment of the present application, a centrifuge tube oscillation device is provided, including: a chassis 10 and a bracket 20.

[0034] On the top surface of the chassis 10, a plurality of oscillation bars 11 are provided. The plurality of oscillation bars 11 are adjacent to each other in sequence along a first direction. The dimension of the oscillation bar 11 along the first direction continuously increases from the side away from the top surface to the side close to the top surface. An oscillation groove 111 is formed between adjacent oscillation bars 11. The first direction is parallel to the length direction of the chassis 10.

[0035] The bracket 20 is located above the chassis 10. A plurality of tube holes 21 are formed in the bracket 20 along a second direction. The tube holes 21 are used for detachably plugging and fixing a conical centrifuge tube A. The second direction is perpendicular to the first direction. The length direction of the oscillation bar 11 and the length direction of the bracket 20 are both parallel to the second direction.

[0036] The conical centrifuge tube A includes a centrifuge tube main body A1 and a centrifuge tube cover A2. The aperture of the tube hole 21 is larger than the radial dimension of the centrifuge tube main body A1, but smaller than the radial dimension of the centrifuge tube cover A2. When the conical centrifuge tube A is plugged and fixed on the tube hole 21, a part of the structure of the conical tube A12 in the centrifuge tube main body A1 is placed in the oscillation groove 111. At this time, when the bracket 20 is moved along the first direction, the bracket 20 can play an oscillation role on the conical centrifuge tube A thereon.

[0037] Using the centrifuge tube oscillation device in the above embodiment, the bracket 20 is located above the chassis 10. The conical centrifuge tube A is plugged and fixed on the bracket 20. A part of the structure of the conical tube A12 in the centrifuge tube main body A1 is placed in the oscillation groove 111. And, the aperture of the tube hole 21 is larger than the radial dimension of the centrifuge tube main body A1, but smaller than the radial dimension of the centrifuge tube cover A2. In this way, when the bracket 20 is moved along the first direction, the conical tube A12 in the conical centrifuge tube A is stressed due to contact with the groove surface of the oscillation groove 111, so that the conical centrifuge tube A has a certain amplitude of tilting swing relative to the axis of the tube hole 21. The conical tube A12 of the conical centrifuge tube A sequentially passes through different oscillation grooves 111 as the bracket 20 moves. In this process, a changing force is successively applied to the conical tube A12 in the conical centrifuge tube A through the plurality of oscillation bars 11 and the plurality of oscillation grooves 111 formed by the plurality of oscillation bars 11, so that the precipitate in the conical tube A12 of the conical centrifuge tube A can be resuspended. The designed bracket 20 is provided with a plurality of tube holes 21 along the second direction, and correspondingly, a plurality of conical centrifuge tubes A can be placed. In this way, when the bracket 20 is moved along the first direction, the conical tubes A12 in a plurality of conical centrifuge tubes A can be simultaneously subjected to precipitate resuspension, improving the centrifuge tube oscillation efficiency. During the use of the centrifuge tube oscillation device, there is no need to plug in the power. With one hand, the bracket 20 can be moved back and forth or unidirectionally on the chassis 10, breaking free from the geographical limitation of wire operation and being more convenient to use.

[0038] The structure of the conical centrifuge tube A is as follows Figure 3 shown, including a detachable centrifuge tube body A1 and a centrifuge tube cover A2. The centrifuge tube body A1 includes a main tube A11 and a conical tube A12 that are integrally connected along the axial direction. The bottom sediment of the conical centrifuge tube A, that is, the sediment in the conical tube A12 in this application. A part of the structure of the conical tube A12 is located in the oscillation groove 111. For example, 1 / 3 - 1 / 4 of the length of the bottom of the conical tube A12 (i.e., the side of the conical tube A12 away from the main tube A11) in the axial direction is placed in the oscillation groove 111. In this range, it is convenient for the conical centrifuge tube A to move in different oscillation grooves 111, and it can also ensure that the oscillation groove 111 can apply an appropriate force to the conical tube A12 in the conical centrifuge tube A to ensure that the sediment in the conical tube A12 can be resuspended. Specifically, the conical centrifuge tube A is, for example, a 1.5 ml conical centrifuge tube. In other embodiments, it can also be conical centrifuge tubes of other capacities, and the parameters of the centrifuge tube oscillation device can be correspondingly adjusted to be adapted to the size of the conical centrifuge tube.

[0039] Among them, in the embodiment of this application, the cross-sectional shape of the oscillation bar 11 can specifically be triangular (for example, as Figure 1 shown), trapezoidal (for example, as Figure 4 shown), semi-elliptical (for example, as Figure 5 shown) or semi-circular. Here, only the cross-sectional shape of the oscillation bar 11 is listed. As long as the dimension of the oscillation bar 11 along the first direction continuously increases from the side away from the top surface to the side close to the top surface. A plurality of oscillation bars 11 are connected to form a stepped wave surface approximately, so as to facilitate the oscillation and resuspension of the sediment in the conical tube A12. The so-called top surface refers to the relatively upper end face on the chassis 10 along the third direction, as Figure 1 shown, and the first direction, the second direction and the third direction are perpendicular to each other.

[0040] Taking Figure 4 as an example to illustrate the force condition of the conical centrifuge tube A when moving with the bracket 20. When the bracket 20 moves from left to right, the conical tube A12 in the conical centrifuge tube A passes through the oscillation bar 11, the oscillation groove 111, the oscillation bar 11, the oscillation groove 111... in sequence. In the up and down direction, the conical tube A12 in the conical centrifuge tube A goes from top to bottom, from bottom to top, from top to bottom, from bottom to top... in sequence. In this process, the conical tube A12 is subjected to a force whose magnitude and direction both change periodically, and can regularly resuspend the sediment in the conical tube A12 to ensure the resuspension effect.

[0041] For ease of processing, the shock bar 11 and the chassis 10 are of an integral structure, that is, the shock bar 11 belongs to a part of the chassis 10. To ensure that when the chassis 10 contacts the conical tube A12, the chassis 10 can provide sufficient stress, the chassis 10 is made of a hard material, such as a strong plastic, such as PET, PA6, POM, PBT, PS, and ABS.

[0042] Preferably, in the embodiment of the present application, the aperture of the tube hole 21 is 1 mm - 2 mm larger than the radial dimension of the centrifuge tube body A1. Within this range, a swinging space can be provided for the main tube A11 of the conical centrifuge tube A in the tube hole 21, so that the conical centrifuge tube A can be tilted to a certain extent when passing through different shock bars 11 or shock grooves 111. If this range is too small, it is not conducive to the tilting of the conical centrifuge tube A, making it impossible for the conical centrifuge tube A to smoothly pass through different shock bars 11 or shock grooves 111. If this range is too large, the swinging space of the conical centrifuge tube A relative to the tube hole 21 is too large, which is not conducive to the installation stability of the conical centrifuge tube A.

[0043] Preferably, the thickness of the bracket 20 is 1 cm - 1.5 cm. When the thickness of the bracket 20 is too small, the structural strength cannot be guaranteed. When the thickness of the bracket 20 is too large, there is a greater limitation on the swinging space of the conical centrifuge tube A. Within this thickness range, the structural strength of the bracket 20 and the swinging space of the conical centrifuge tube A can be better balanced. Further preferably, the thickness of the bracket 20 is 1.2 cm - 1.3 cm.

[0044] As Figures 1 - 2 shown, the centrifuge tube shock device further includes a guiding structure 30. The bracket 20 and the chassis 10 are connected by the guiding structure 30. The guiding structure 30 is used to play a guiding role when moving along the first direction on the bracket 20. Through the guiding function of the guiding structure 30, the bracket 20 can be moved along the first direction in a more labor-saving manner.

[0045] As Figures 8 - 9 shown, the bracket 20 includes a bracket main board 22 and two bracket side boards 23. The two bracket side boards 23 are respectively located at both ends of the bracket main board 22. As Figure 1As shown, the guiding structure 30 includes an auxiliary mounting member 31, a roller 32, and a guide rail 33. A guiding groove 12 is formed on the chassis 10. One end of the support side plate 23 is connected to the support main board 22. The other end of the support side plate 23 is connected to the auxiliary mounting member 31. The roller 32 is rotatably fixed to the auxiliary mounting member 31, and the guide rail 33 is fixed to the guiding groove 12. The roller 32 is in rolling contact with the guide rail 33. Among them, the two support side plates 23 are parallel to each other, and both of the two support side plates 23 are perpendicular to the support main board 22. The two support side plates 23 and the support main board 22 are generally in a gate-shaped structure. The thickness of the support 20, which refers to the thickness of the support main board 22 at this time, is that the thickness of the support main board 22 is 1 cm - 1.5 cm (or 1.2 cm - 1.3 cm), and the thickness of the support side plate 23 can be flexibly set as needed. The support side plate 23, the guiding structure 30, and the guiding groove 12 are arranged in one-to-one correspondence, that is, both the guiding structure 30 and the guiding groove 12 are two.

[0046] As Figure 6 shown, the auxiliary mounting member 31 includes a first mounting plate 311 and two second mounting plates 312. One side of the first mounting plate 311 is connected to the support side plate 23, and the opposite side of the first mounting plate 311 is respectively connected to one end of the two second mounting plates 312. The roller 32 is connected to the other ends of the two second mounting plates 312 through a rotating shaft 321. Specifically, in the embodiment of the present application, the two second mounting plates 312 are distributed in parallel, and the first mounting plate 311 is fixedly connected to the inner side surface of the support side plate 23 in the second direction of Figure 1 the support, for example, the fixed connection between the first mounting plate 311 and the support side plate 23 is realized by welding or screw connection. The so-called inner side surface refers to the surfaces of the two support side plates 23 close to each other. Correspondingly, as Figure 1 shown, guiding grooves 12 are respectively formed on the opposite end faces of the chassis 10 along the second direction. Preferably, the guide rail 33 is a cylindrical guide rail 33, and the roller 32 has a curved surface adapted to the shape of the guide rail 33. In this way, the roller 32 and the guide rail 33 are in concave-convex cooperation, which can not only play a role in supporting and limiting, but also reduce the moving resistance of the support 20. In other embodiments, as Figure 7 shown, guiding grooves 12 can also be formed on both sides of the top surface of the chassis 10 along the second direction. At this time, correspondingly, the first mounting plate 311 is connected to the end face of the support side plate 23 along the third direction. In other embodiments, the guiding structure 30 can also be a ball, the ball is rotatably fixed on the support side plate 23, and the ball is in rolling contact with the guiding groove 12. Or, in other embodiments, the guiding structure 30 can also be a slider and a slide bar. The slider is fixed on the support side plate 23, the slide bar is fixed in the guiding groove 12, and the slider and the slide bar are sleeved and in sliding contact.

[0047] Preferably, as Figures 1 - 2 and Figures 8 - 10As shown, in the embodiment of the present application, a plurality of brackets 20 may be configured. Along the first direction, splicing bumps 24 (such as two splicing bumps 24) are provided on one side surface of the bracket 20, and splicing grooves 25 (such as two splicing grooves 25) corresponding to the positions of the splicing bumps 24 are formed on the other side surface of the bracket 20. The splicing bumps 24 and the splicing grooves 25 between adjacent brackets 20 are in concave-convex fit to achieve detachable connection of adjacent brackets 20. The splicing between the spliced brackets 20 is similar to the way of building blocks. By matching the splicing bumps 24 on one bracket 20 with the splicing grooves 25 on an adjacent other bracket 20, a plurality of brackets 20 can be assembled side by side, so that a plurality of brackets 20 can be moved simultaneously, and further, more conical centrifuge tubes A can be moved to realize batch oscillation of the conical centrifuge tubes A. For example, as Figure 10 shown, when 3 brackets 20 are assembled, taking the example that 8 tube holes 21 are formed on the bracket 20, when moving the assembled 3 brackets 20, oscillation can be applied to 24 conical centrifuge tubes A at the same time. In addition to the way of assembling a plurality of brackets 20 side by side to increase the number of conical centrifuge tubes A moved at one time, the number of conical centrifuge tubes A moved at one time can also be increased by increasing the number of tube holes 21 on the bracket 20.

[0048] Specifically, the centrifuge tube cover A2 is a press-on cover, and the centrifuge tube oscillation device further includes a protective frame 40. The protective frame 40 is provided with a plurality of protective grooves 41 along the second direction. The protective grooves 41 are arranged in one-to-one correspondence with the tube holes 21, and the outer shape of the protective grooves 41 is adapted to the outer shape of the centrifuge tube cover A2, so that the centrifuge tube cover A2 can be placed in the protective grooves 41. The protective frame 40 is used to be fixed on the bracket 20 to fix the centrifuge tube covers A2 on the bracket 20. When the centrifuge tube cover A2 is a press-on cover, since there will be a strong mechanical oscillation effect during the oscillation of the conical tube A12 of the conical centrifuge tube A, the centrifuge tube cover A2 may be separated from the centrifuge tube body A1. If the centrifuge tube cover A2 is separated from the centrifuge tube body A1 during the oscillation of the conical centrifuge tube A, the liquid in the centrifuge tube body A1 is very likely to spill out due to the oscillation, causing pollution to the surrounding environment. At this time, the protective frame 40 can fix a plurality of centrifuge tube covers A2 on the bracket 20 at the same time, preventing the centrifuge tube covers A2 from separating from the centrifuge tube body A1 and ensuring the effective progress of the oscillation work.

[0049] More specifically, the main body of the bracket 20 and the protective frame 40 are both rectangular parallelepiped-shaped. The outer dimension of the protective frame 40 may be the same as or different from the outer dimension of the main body of the bracket 20, as long as the protective grooves 41 on the protective frame 40 can fix the centrifuge tube covers A2, and no specific limitation is made.

[0050] In other embodiments, if the centrifuge tube cap A2 is a threaded cap and the centrifuge tube cap A2 is threadedly connected to the centrifuge tube body A1, the protective frame 40 does not need to be provided.

[0051] Preferably, in the embodiments of the present application, the protective frame 40 is rotatably connected to the bracket 20 through the connecting member 50, and the connecting member 50 is a torsion spring or a hinge. For example, as Figure 11 shown, the connecting member 50 is a hinge. The protective frame 40 is movably fixed to the bracket 20 through the connecting member 50. On the one hand, it has the function of preventing the protective frame 40 from being lost. On the other hand, it is more convenient to use the protective frame 40. By rotating the protective frame 40, the centrifuge tube cap A2 on the bracket 20 can be fixed, or the protective frame 40 and the centrifuge tube cap A2 can be separated, and the centrifuge tube cap A2 is exposed on the bracket 20. In other embodiments, the protective frame 40 can also be taken off the bracket 20, that is, the protective frame 40 and the bracket 20 are a detachable structure. For example, the protective frame 40 and the bracket 20 are snap-connected after being inserted, so that the protective frame 40 and the bracket 20 can be detached.

[0052] As Figure 1 shown, in the embodiments of the present application, an operation part 42 is provided on the protective frame 40, and the operation part 42 is used for the protective frame 40 to be in an open state or a closed state. In the open state, the centrifuge tube cap A2 is separated from the protective groove 41. In the closed state, the centrifuge tube cap A2 is placed in the protective groove 41. Specifically, the operation part 42 is in the shape of a groove, a convex block or a handle, so as to facilitate the staff to operate the protective frame 40.

[0053] By using the centrifuge tube shaking device designed in the above embodiments of the present application, the resuspension of the precipitate at the bottom of the conical centrifuge tube after high-speed centrifugation can be achieved, and it is particularly suitable for the conical centrifuge tube A in the nucleic acid extraction and amplification kit. The conical centrifuge tube A can be shaken through the mechanical structure, breaking free from the geographical limitations of wire operation. The plurality of shaking bars 11 and the plurality of shaking grooves 111 can perform strong mechanical shaking on the conical centrifuge tube A to resuspend the precipitate deposited in the conical tube A12 after high-speed centrifugation. When using the centrifuge tube shaking device, there is no need to hold the centrifuge tube by hand, and multiple conical centrifuge tubes A can be shaken at one time with one hand, making the shaking work more convenient and efficient.

[0054] It should be noted that the first direction, the second direction and the third direction mentioned in the present application all correspond and are consistent with Figure 1 the first direction, the second direction and the third direction therein. The orientation words such as up, down, left and right mentioned in the present application are only for more clearly describing the structure or the use principle of the present application, and should not be construed as a limitation to the present application.

[0055] The above uses specific examples to elaborate on this application, which is only used to help understand this application and is not intended to limit this application. For those skilled in the technical field to which this application pertains, based on the idea of this application, several simple deductions, deformations, or substitutions can also be made.
