Description

Technical Field

[0001] This utility model relates to the field of pipe rack technology, specifically a multi-diameter pipe rack. Background Technology

[0002] Tube racks are the most basic experimental instruments and equipment in the laboratory. In aseptic experimental environments such as cell culture and microbial operations, the laminar flow hood is the core operating area. In order to minimize the risk of bacterial contamination, the operating procedures require that the items placed on the laminar flow hood in the cell culture room be simplified (fewer items).

[0003] However, since cell experiments often require 50ml, 15ml, and 1.5ml tubes to hold various reagents, existing racks are often single-pore size or 15ml / 1.5ml / 50ml pore size, which cannot simultaneously meet the needs of various pore sizes. That is, a single tube rack cannot meet the needs, and placing multiple tube racks will make the laminar flow hood less streamlined. In addition, the frequent transfer and replacement of tube racks from inside and outside the laminar flow hood can easily directly disrupt the integrity of the sterile environment. Therefore, it is necessary to study and design how to place tubes of various sizes in a more streamlined way. Hence, a multi-pore tube rack is proposed. Utility Model Content

[0004] Based on the above description, this utility model provides a multi-aperture pipe rack, which solves the technical problems pointed out in the background art.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A multi-aperture pipe rack, comprising:

[0006] Base;

[0007] The first tube rack is set above the base, and a support column is fixed between the base and the first tube rack. The first tube rack has multiple holes one and multiple holes two, which are used to hold 1.5ml microcentrifuge tubes and 15ml centrifuge tubes, respectively.

[0008] The second tube rack is rotatably mounted on the outside of the support column. A support sleeve is fixed at the bottom of the second tube rack. The second tube rack has a third hole for accommodating 50ml centrifuge tubes. The second tube rack also has a fourth hole.

[0009] The elastic pressing structure includes a pressing member and a spring. The pressing member is sleeved on the outside of the support column, and the spring is sleeved on the outside of the support column and located between the pressing member and the first pipe rack, so that the pressing member can press down on the second pipe rack.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the diameter of hole four is equal to the diameter of hole one, and hole four is located directly below hole one.

[0012] Furthermore, the lower pressure component consists of an upper sliding plate, a lower pressure plate, and a connecting column. The connecting column is fixed between the upper sliding plate and the lower pressure plate. A spring is sleeved between the upper sliding plate and the first pipe support. The multi-hole pipe support also includes a protective sleeve. The protective sleeve is fixed to the bottom of the first pipe support and is coaxially arranged with the support column. The diameter of the upper sliding plate is equal to the inner diameter of the protective sleeve and is slidably connected in the protective sleeve. A sliding hole is opened at the bottom of the protective sleeve. The connecting column is located inside this sliding hole, and the two are matched in size. The lower pressure plate is located below the protective sleeve and is in contact with the upper surface of the second pipe support.

[0013] Furthermore, the second tube rack has four sets of semi-circular cavities arranged in a circumferential array, and a hemisphere is fixed at the bottom of the lower pressure plate, the hemisphere being adapted to the semi-circular cavity.

[0014] Furthermore, the radius of the hemisphere is smaller than the distance between the protective sleeve and the lower pressure plate.

[0015] Furthermore, the base has a lower hole with two sizes, corresponding to hole one and hole two respectively. Multiple silicone pads are fixed in the lower hole in a circular array.

[0016] Furthermore, there are nine holes in total, arranged in three rows and three columns, and eight holes in total, arranged in two rows and four columns.

[0017] Furthermore, the second pipe support has mounting holes with a diameter equal to that of the support column, allowing the second pipe support to be rotatably connected to the outside of the support column through the mounting holes.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0019] This multi-pore tube rack, with its rotatable, outward-expanding and inward-retracting second tube rack, can provide an additional 50ml of centrifuge tubes without increasing the length and width of the first tube rack. This streamlines the multi-pore tube rack and can accommodate tubes of 50ml, 15ml, and 1.5ml sizes. In addition, it eliminates the need for frequent tube rack replacements, reducing the transfer of items between the inside and outside of the clean bench and mitigating the risk of contamination.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] like Figure 1-7 As shown in this embodiment, a multi-pore tube rack is mainly used in a clean bench in cell experiments to hold 50ml and 15ml centrifuge tubes and 1.5ml microcentrifuge tubes. It is understood, and it should be noted, that the multi-pore tube rack can also be used in other biological experimental operations, that is, the multi-pore tube rack can accommodate test tubes of corresponding specifications, and the multi-pore tube rack can be used both inside and outside the clean bench.

[0031] In this embodiment, the multi-pore tube rack includes a base 1, on which a support column 2 is fixedly mounted. The number of support columns 2 is preferably four sets. A first tube rack 3 is fixed above the base 1 and fixed to the top of the support column 2. The first tube rack 3 has holes 31 and holes 32. There are nine holes 31 in total, arranged in three rows and three columns. In a clean bench for cell experiments, these holes are used to hold 1.5 ml microcentrifuge tubes. It can be understood that holes 31 can also be designed to hold 2 ml microcentrifuge tubes. There are eight holes 32 in total, arranged in two rows and four columns. In a clean bench for cell experiments, these holes are used to hold 15 ml centrifuge tubes. In this way, it can support the placement of two common centrifuge tubes with different pore sizes.

[0032] In the clean bench used for cell experiments, to provide additional space for 50ml centrifuge tubes without increasing the length and width of the first tube rack 3, the multi-well tube rack in this embodiment also includes a second tube rack 4. For example, there are four sets of second tube racks 4, which are spaced apart between the base 1 and the first tube rack 3 and are rotatably mounted on the outside of the support column 2. The second tube rack 4 has three holes 41, for example, two holes 41, for accommodating 50ml centrifuge tubes. In this way, it can support the placement of three common centrifuge tubes with different pore sizes. In addition, since the second tube rack 4 is designed to rotatably expand outward and retract inward, it can provide additional space for 50ml centrifuge tubes without increasing the length and width of the first tube rack 3, making the multi-well tube rack streamlined and able to accommodate 50ml, 15ml and 1.5ml tubes at the same time.

[0033] It should be noted that the second pipe rack 4 is also provided with a hole four. The diameter of hole four is equal to the diameter of hole one 31. Under normal conditions, the second pipe rack 4 is in a retracted state, and hole four is located directly below hole one 31 to avoid interference when a pipe is placed at hole one 31.

[0034] Further explanation: The second pipe rack 4 has mounting holes with a diameter equal to that of the support column 2. This allows the second pipe rack 4 to be rotatably connected to the outside of the support column 2 through the mounting holes. A support sleeve 5 is fixed at the bottom of the second pipe rack 4, with the bottom end of the support sleeve 5 fitting against the upper surface of the base 1. The porous pipe rack also includes an elastic pressing structure 6, which is located on the outside of the support column 2 and includes a pressing member 61 and a spring 62. The pressing member 61 is sleeved on the outside of the support column 2, and the spring 62 is sleeved on the outside of the support column 2 and located between the pressing member 61 and the first pipe rack 3. Under normal conditions, the spring 62 is in a compressed state, and the pressing member 61 is required to press down on the second pipe rack 4 to prevent the second pipe rack 4 from rotating arbitrarily without external force.

[0035] It should also be noted that the lower pressure component 61 consists of an upper sliding plate, a lower pressure plate, and a connecting column. The connecting column is fixed between the upper sliding plate and the lower pressure plate. At this time, the spring 62 is specifically sleeved between the upper sliding plate and the first tube frame 3.

[0036] To conceal the spring 62, the perforated tube rack also includes a protective sleeve 7. The protective sleeve 7 is fixed to the bottom of the first tube rack 3 and is coaxially arranged with the support column 2. The diameter of the upper sliding plate is equal to the inner diameter of the protective sleeve 7 and is slidably connected in the protective sleeve 7. A sliding hole is opened at the bottom of the protective sleeve 7, and the connecting column is located inside this sliding hole, and the two are matched in size. The lower pressure plate is located below the protective sleeve 7 and contacts the upper surface of the second tube rack 4. In this way, under normal conditions, the spring 62 is located in the protective sleeve 7, which can protect it.

[0037] In addition, since the rotation angle of the second pipe rack 4 is generally ninety degrees or one hundred and eighty degrees, in order to let the operator know whether the second pipe rack 4 has rotated ninety degrees or one hundred and eighty degrees, four sets of semi-circular cavities are opened on the second pipe rack 4 in a circular array, and a hemisphere is fixed at the bottom of the pressure plate, and the hemisphere is adapted to the semi-circular cavity.

[0038] It should be noted that the radius of the hemisphere is smaller than the distance between the casing 7 and the lower pressure plate. In this way, when the operator rotates the second pipe rack 4, the hemisphere can detach from the hemisphere cavity. After rotation, when the hemisphere enters another adjacent hemisphere cavity, the operator can know that the second pipe rack 4 has rotated 90 degrees. When it continues to rotate to the next hemisphere cavity, the operator can know that the second pipe rack 4 has rotated 180 degrees.

[0039] With this design, under normal conditions, the second tube rack 4 is in a retracted state. At this time, since the diameter of hole 3 41 is larger than that of hole 1 31 and hole 2 32, it does not affect the placement of the 15ml centrifuge tube at hole 2 32. When the second tube rack 4 rotates around the support column 2, it expands outward. In this way, it can provide an additional 50ml of centrifuge tube placement without increasing the length and width of the first tube rack 3.

[0040] In addition, to stabilize the placed tubes, the base 1 has two sizes of holes, corresponding to holes 31 and 32 respectively. Both holes have multiple silicone pads arranged in a circular array fixed within them. When the bottom of a tube passes between these silicone pads, the pads fold downwards. Due to their resilience, these pads create a clamping force on the tube, thus reinforcing it and making the tube placement more stable. Of course, further design considerations could lead to further improvements. Figure 6-7 As shown, a tube seat 8 is also fixed to the outside of the support sleeve 5, allowing the tube seat 8 to rotate synchronously with the second tube rack 4. The tube seat 8 is located below the second tube rack 4, and a through hole corresponding to the hole 4 is opened on the tube seat 8 to avoid interference. In addition, a perforation is also opened on the tube seat 8, in which multiple silicone pads II are arranged in a circumferential array. Similarly, when the second tube rack 4 is rotated, for example, 90 degrees, and a 50ml centrifuge tube is placed on the second tube rack 4, the silicone pads II can form a clamping force on the 50ml centrifuge tube, thereby reinforcing the 50ml centrifuge tube. When the tube seat 8 is designed, when the second tube rack 4 is unfolded and a 50ml centrifuge tube is placed, after the 50ml centrifuge tube is placed, the silicone pads II flip downwards, and then use their rebound energy to form a clamping force on the tube, thereby reinforcing the tube. See the schematic diagram of the second tube rack 4 unfolded and a 50ml tube is placed. Figure 7 .

[0041] In conclusion:

[0042] Initial state: The second tube rack 4 is in a retracted state. The hemispherical part of the elastic pressing structure 6 is embedded in the hemispherical cavity of the second tube rack 4, locking the position to prevent random rotation. It is located between the first tube rack 3 and the base 1. When viewed from above, it is blocked by the first tube rack 3. At this time, the third hole 41 on the second tube rack 4 is located directly below the second hole 32 on the first tube rack 3, which does not affect the placement of the tubes at the second hole 32. The fourth hole is located directly below the first hole 31, which does not affect the placement of the tubes at the first hole 31. This is the state of the multi-pore tube rack when the second tube rack 4 is not needed to place 50ml centrifuge tubes.

[0043] Deployment status and operation process: Press down on the first tube frame 3 with one hand, and provide rotational thrust to the second tube frame 4 with the other hand. Rotate outward by 90° or 180° with the support column 2 as the axis. Every time it rotates 90°, the hemisphere will fall into the next hemisphere cavity, producing a "click" sound and tactile feedback, indicating that the deployment is in place.

[0044] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
