Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of laboratory equipment, in particular to a centrifuge tube rack. Background Art
[0002] Centrifuge tubes are widely used in experimental operations to hold reactants. In the process of biological sample experiments and sample detection, it often involves the determination of more samples, and multiple reaction liquids must be added in steps. The reaction liquid contains liquid for detecting samples and other liquid reagents required for the reaction. During the implementation of the experiment, it is usually necessary to use a pipette to put various reaction liquids into the centrifuge tube in a certain order, and then place them in the corresponding instruments for inspection.
[0003] When it comes to testing a large number of samples, a certain number of centrifuge tubes are usually placed on a centrifuge tube carrier, and then the samples to be tested and various liquid reagents are added to each centrifuge tube one by one in a certain order according to the experimental plan.
[0004] The centrifuge tubes on the market are generally divided into installation type and integrated type. 1. The centrifuge tube rack formed by the installation method needs to be manually installed before it can be used, and the sockets of the centrifuge tubes set on it are generally staggered in size, which is inconvenient to use. Due to the heavy weight and large size of the bracket, it occupies a large space when in use, causing space waste, and is inconvenient for experimenters to perform experimental operations. 2. The socket of the integrated centrifuge tube rack is formed during manufacturing, which is heavy and cannot be placed at the same time for different types of centrifuge tubes. It is also inconvenient when transporting and storing experimental equipment.
[0005] Therefore, in view of the above technical problems, it is urgent to design a centrifuge tube rack that can be quickly disassembled and assembled and can be conveniently stored by experimenters. Utility Model Content
[0006] The purpose of the utility model is to provide a centrifuge tube rack to solve the problems raised in the above background technology. The following technical solution is provided: a centrifuge tube rack, comprising a base:
[0007] A bottom plate is fixedly provided at the upper end of the base, a disassembly head is symmetrically provided on the bottom plate, and a support rod is rotatably provided on the disassembly head;
[0008] The top plate, the lower end surface of the top plate is also fixedly provided with a disassembly head, and the other end of the support rod is rotatably arranged in the disassembly head located at the lower side of the top plate; the bottom plate and the top plate are respectively provided with test tube holes.
[0009] In this technical solution, the bottom plate and the top plate are always parallel to each other, and the surfaces of the bottom plate and the top plate are respectively provided with installation grooves for installing the disassembly head. The bottom plate, the top plate, and the support rod form a parallelogram structure, so that the bracket can be retracted and extended, so that it is convenient for operators to reasonably use the space. Furthermore, the disassembly head and the support rod can be rotated in a limited position, so that the overall height of the bracket can be selected by the experimenter, and it is also convenient for the overall storage after the experimental operation.
[0010] Test tube holes of different sizes can be opened in the bottom plate and the top plate respectively. When centrifuge tubes of different sizes need to be placed during the experiment, the operator can choose the top plate of the appropriate size for quick replacement.
[0011] In any of the above technical solutions, further, a through hole is opened in the middle of the disassembly head, and an I-shaped block is fixedly connected to one end of the through hole. A mounting groove is fixedly provided at the upper end surface of the bottom plate, and a limit strip is fixedly provided at the upper end of the mounting groove, and the I-shaped block can be embedded in the mounting groove and fixed to the mounting groove.
[0012] In the present technical solution, when installing the I-block, first press the I-block from the opening on the upper side of the installation groove, and then move the I-block horizontally so that it is horizontally embedded under the limit bar. At this time, the limit bar and the upper end of the I-block fit tightly together to achieve the installation and fixation of the disassembly head and the base plate. When the bracket needs to be transported or cleaned, the entire bracket can be quickly disassembled by simply removing the I-block from the installation groove.
[0013] In any of the above technical solutions, further, snaps are fixedly provided at both ends of the support rod, and the snaps are rotatably arranged in the through hole. A locking cap is provided at the other end surface of the snap to prevent the snap from detaching, and the locking cap is always in close contact with the end surface of the through hole.
[0014] A rib plate is also arranged at the middle of the support plate. The snap button and the through hole are respectively in the shape of a "M"-shaped circular ring, the snap button is interference-connected in the through hole, and can be limitedly rotated with the through hole.
[0015] In the present technical solution, since the through hole and the snap button are respectively arranged in a "M"-shaped circular ring, when the snap button and the through hole rotate, the interval angle between adjacent protrusions is degrees, so the bracket can adjust the gear position by rotating at different angles.
[0016] 1. The first gear is 0°, that is, the bottom plate and the top plate overlap at this time. At this time, the centrifuge tube rack is in a folded state, which can reduce the volume, facilitate transportation and storage, and leave more experimental table space for laboratories and biosafety cabinets / fume hoods.
[0017] 2. The second gear is 45 / 135°, which can make the centrifuge tube rack tilted (either left or right), so that the experimenter can easily suck out as much upper liquid in the centrifuge tube as possible.
[0018] When the diameter of the selected test tube hole is larger than the diameter of the centrifuge tube, the upper end of the centrifuge tube will tilt along with the translation of the top plate, and the centrifuge tube can be tilted so that the sample can be added along the tube wall, which meets the experimental scenario of adding samples to the upper layer of the liquid without damaging the lower liquid surface or precipitation (such as blood sample PBMC separation preparation experiment, single cell suspension preparation experiment and other experiments requiring density gradient centrifugation). This tilted structure of the centrifuge tube rack has a buffering effect on the addition of liquid, and is also conducive to freeing the hands of the experimenter.
[0019] 3. The third gear is 90°, which can make the centrifuge tube rack vertical, making it convenient for experimenters to perform various vertical operations on the centrifuge tubes. For example, the pipette needs to be operated vertically to avoid errors. Or it is convenient for cells or other components to settle to the bottom and facilitate stratification. Switching back and forth between the second and third gears is more conducive to the experiment and saves more manpower.
[0020] The beneficial effects of the utility model are as follows: the disassembly head and the support rod in the present application respectively adopt a "M"-shaped structure, thereby realizing the free adjustment of the rotation angles of the two, and the design of the M-shaped structure ensures the stability of the swing angle of the parallelogram mechanism composed of the bottom plate, the support rod and the top plate, so that the device can perform stable adjustment of multiple gears, thereby freeing the operator's hands when conducting density gradient centrifugation experiments; at the same time, the disassembly head can be quickly disassembled and assembled with the bottom plate and the top plate, and the operator can independently replace and select the top plate with a suitable test tube mouth for centrifuge tubes of different sizes, thereby making adaptive adjustments to the experimental equipment.

[0030] Embodiment 1:
[0031] like Figure 1-2 As shown, this embodiment provides a centrifuge tube rack, comprising:
[0032] A bottom plate 20 is fixedly provided at the upper end of the base 10, a disassembly head 40 is symmetrically provided on the bottom plate 20, and a support rod 50 is rotatably provided on the disassembly head 40;
[0033] The top plate 30 is also fixed with a disassembly head 40 at the lower end surface of the top plate 30, and the other end of the support rod 50 is rotatably set in the disassembly head 40 located at the lower side of the top plate 30; the bottom plate 20 and the top plate 30 are respectively provided with test tube holes 60.
[0034] In the present technical solution, the bottom plate 20 and the top plate 30 are always parallel to each other, and the surfaces of the bottom plate 20 and the top plate 30 are respectively provided with installation grooves for installing the disassembly head 40. The bottom plate 20, the top plate 30, and the support rod 50 form a parallelogram structure, so that the bracket can be retracted and extended, so as to facilitate the operator to reasonably use the space. Furthermore, the disassembly head 40 and the support rod 50 can be limited and rotated, so as to ensure that the overall height of the bracket can be selected by the experimenter, and it is also convenient for the overall storage after the experimental operation.
[0035] Test tube holes 60 of different sizes can be respectively opened in the bottom plate 20 and the top plate 30. When centrifuge tubes of different sizes need to be placed during the experiment, the operator can select the top plate 30 of the appropriate size for quick replacement.
[0036] In a preferred embodiment of the present invention:
[0037] like Figure 2 , 4 5, specifically, a through hole 41 is opened in the middle of the disassembly head 40, and an I-shaped block 42 is fixedly connected to one end of the through hole 41. A mounting groove 21 is fixedly provided at the upper end surface of the bottom plate 20, and a limit strip 22 is fixedly provided at the upper end of the mounting groove 21, and the I-shaped block 42 can be embedded in the mounting groove 21 and fixed to the mounting groove 21.
[0038] In the present technical solution, when installing the I-block 42, first press the I-block 42 from the opening on the upper side of the installation groove 21, and then move the I-block 42 horizontally so that it is horizontally embedded under the limit bar 22. At this time, the limit bar 22 and the upper end of the I-block 42 fit tightly together to achieve the installation and fixation of the disassembly head 40 and the base plate 20. When the bracket needs to be transported or cleaned, the entire bracket can be quickly disassembled by simply removing and separating the I-block 42 from the installation groove 21.
[0039] In a preferred embodiment of the present invention:
[0040] like Figure 1 , 2 As shown in FIGS. 3 and 6 , specifically, snap buttons 51 are fixedly provided at both ends of the support rod 50, and the snap buttons 51 are rotatably arranged in the through hole 41. A locking cap 53 is provided at the other end surface of the snap button 51 to prevent the snap button 51 from being separated, and the locking cap 53 is always in close contact with the end surface of the through hole 41.

The snap button 51 and the through hole 41 are respectively in the shape of a "M"-shaped circular ring, and the snap button 51 is interference-connected in the through hole 41 and can rotate with the through hole 41 in a limited position.
[0042] In the present technical solution, since the through hole 41 and the snap button 51 are respectively arranged in a "M"-shaped circular ring, when the snap button 51 and the through hole 41 rotate, the interval angle between adjacent protrusions is 45 degrees, so the bracket can adjust the gear position by rotating at different angles.
[0043] 1. The first gear is 0°, that is, the bottom plate 20 and the top plate 30 overlap at this time, and the centrifuge tube rack is in a folded state, which can reduce the volume, facilitate transportation and storage, and leave more experimental table space for laboratories and biosafety cabinets / fume hoods.
[0044] 2. The second gear is 45 / 135°, which can make the centrifuge tube rack tilted (either left or right), so that the experimenter can easily suck out as much upper liquid in the centrifuge tube as possible.
[0045] When the diameter of the selected test tube hole 60 is larger than the diameter of the centrifuge tube, the upper end of the centrifuge tube will tilt along with the translation of the top plate 30, and the centrifuge tube will tilt so that the sample can be added along the tube wall, which meets the experimental scenario of adding the sample to the upper layer of the liquid without damaging the lower liquid surface or precipitation (such as blood sample PBMC separation preparation experiment, single cell suspension preparation experiment and other experiments requiring density gradient centrifugation). This inclined structure of the centrifuge tube rack has a buffering effect on the addition of liquid, and is also conducive to freeing the hands of the experimenter.
[0046] 3. The third gear is 90°, which can make the centrifuge tube rack vertical, making it convenient for experimenters to perform various vertical operations on the centrifuge tubes. For example, the pipette needs to be operated vertically to avoid errors. Or it is convenient for cells or other components to settle to the bottom and facilitate stratification. Switching back and forth between the second and third gears is more conducive to the experiment and saves more manpower.

In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
