Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, specifically a centrifuge tube rack that facilitates the placement and retrieval of centrifuge tubes. Background Technology

[0002] In experimental fields such as biology and chemistry, centrifuge tubes are commonly used experimental instruments for holding various experimental samples and performing centrifugation operations. Centrifuge tube racks are tools used to place centrifuge tubes, which can arrange multiple centrifuge tubes in an orderly manner, making it convenient for experimental personnel to manage and use them.

[0003] Reference announcement number CN217249063U describes a centrifuge tube rack for easy placement and retrieval of centrifuge tubes. The rack includes a base, a side plate, a first support rod, and a second support rod. The first and second support rods are respectively located at both ends of the side plate. The height of the first support rod is less than the height of the second support rod. Both the first and second support rods have multiple slots for a centrifuge tube fixing plate to be inserted. The centrifuge tube fixing plate is movably and inclinedly mounted on the base through the slots. The centrifuge tube fixing plate has several fixing holes of different sizes. The diameter of the fixing holes on the first support rod side is smaller than that on the second support rod side. This centrifuge tube rack can be fixed to the centrifuge tube mounting plate through the fixing holes. Compared with existing technologies, this centrifuge tube rack has the following advantages: while ensuring strong compatibility, it makes full use of space and prevents waste of space. At the same time, it allows the experimenter to clearly see each centrifuge tube and the liquid inside, thus facilitating the aspiration of the liquid from the centrifuge tube. As can be seen from the above, although this centrifuge tube rack can be used well, it is usually not convenient to lift the centrifuge tubes after they are installed, which makes it difficult to put the centrifuge tubes in and out, and there are some inconveniences in use. Utility Model Content

[0004] The purpose of this utility model is to provide a centrifuge tube rack that facilitates the placement and retrieval of centrifuge tubes, thereby solving the problem mentioned in the background art that although centrifuge tube racks can be used well, they are usually not convenient for lifting the placed centrifuge tubes upwards, thus making it difficult to place and retrieve the centrifuge tubes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge tube rack for easy placement and retrieval of centrifuge tubes, comprising a base plate, a support at the center of the top of the base plate, a vertical shaft rotatably mounted on the top of the support, a gear fixedly mounted on the outer wall of the vertical shaft, a turntable fixedly mounted on the top of the vertical shaft, a frame base at the top of the turntable, a plurality of cylindrical frames inside the frame base, each cylindrical frame having a cylindrical tube placement cavity inside, a lifting plate movably mounted at the lower end of the cylindrical tube placement cavity, a micro motor installed inside the cylindrical frame on one side of the cylindrical tube placement cavity, one end of the micro motor extending into the cylindrical tube placement cavity and having a first conical tooth installed thereon, a second conical tooth rotatably mounted at the bottom of the cylindrical tube placement cavity on one side of the first conical tooth, the second conical tooth meshing with the first conical tooth, a control panel mounted on the top of the base plate on one side of the support, the output of a microcontroller inside the control panel being electrically connected to the input of the micro motor.

[0006] Preferably, a U-shaped support frame is installed at the top of the base plate on the side of the stand away from the control panel, and a limit frame is fixed at the top of the U-shaped support frame to allow for the movable placement of the rack.

[0007] Preferably, a rack is slidably installed inside the limiting frame, and the rack meshes with a gear. The meshing of the rack and gear drives the gear to rotate when the rack translates.

[0008] Preferably, an electric push rod is installed on the outer wall of the limiting frame. The input end of the electric push rod is electrically connected to the output end of the microcontroller inside the control panel. One end of the electric push rod is connected to the outer wall of one end of the rack through a bracket. The electric push rod is configured to drive the rack to translate.

[0009] Preferably, a lead screw is fixedly installed at the center of the tip of the second conical tooth, and a nut pair is threaded on the outer wall of the lower end of the lead screw. The nut pair is provided to facilitate the placement of the connecting rod.

[0010] Preferably, limiting frames are provided on both inner walls of the cylindrical cavity below the lifting plate, and connecting rods are provided on both outer walls of the nut assembly. The end of the connecting rod away from the nut assembly passes through the limiting frame and connects to the bottom end of the lifting plate. The limiting frames limit the movement range of the connecting rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the centrifuge tube rack that facilitates the placement and retrieval of centrifuge tubes not only achieves the purpose of making it easy to place and retrieve centrifuge tubes, but also ensures the storage effect of centrifuge tubes when using the centrifuge tube rack, and improves the convenience of using the centrifuge tube rack.

[0012] (1) The first conical tooth is driven to rotate by a micro motor. Since the first conical tooth and the second conical tooth mesh with each other, and the diameter of the first conical tooth is smaller than the diameter of the second conical tooth, the first conical tooth drives the screw to rotate slowly through the second conical tooth. Since the limit frame limits the movement range of the connecting rod, the nut pair slides upward on the outer wall of the screw, so that the nut pair drives the lifting plate to move upward through the connecting rod, which can slightly lift the centrifuge tube placed inside the cylindrical tube cavity, thereby achieving the purpose of easy picking and putting in the centrifuge tube;

[0013] (2) By setting up several columnar frames, and setting up columnar tube cavities inside the columnar frames, several centrifuge tubes are placed at intervals, which can effectively reduce the phenomenon of collision between centrifuge tubes, thereby ensuring the storage effect of centrifuge tubes when the centrifuge tube rack is used.

[0014] (3) The rack is driven by an electric push rod to slide inside the limit frame. Because the rack and gear mesh with each other, the rack drives the vertical shaft to rotate at the top of the stand, so that the vertical shaft drives the turntable to rotate synchronously. This allows the angle of the stand to be adjusted horizontally. As a result, the centrifuge tubes placed inside the stand can be rotated and moved to the area close to the personnel without the need for personnel to move. This makes it easier for personnel to pick up and put down the centrifuge tubes, thereby improving the convenience of using the centrifuge tube rack. Attached Figure Description

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: a centrifuge tube rack that facilitates the placement and retrieval of centrifuge tubes, including a base plate 1, a stand 6 provided at the center of the top of the base plate 1, a U-shaped support frame 2 installed on the top of the base plate 1 on the side of the stand 6 away from the control panel 20, and a limit frame 3 fixed to the top of the U-shaped support frame 2.

[0022] In use, the rack 5 is movable by setting the limit frame 3;

[0023] A rack 5 is slidably installed inside the limiting frame 3, and the rack 5 meshes with the gear 12.

[0024] In use, the rack 5 meshes with the gear 12 so that the rack 5 drives the gear 12 to rotate when it translates.

[0025] An electric push rod 4 is installed on the outer wall of the limit frame 3. The input end of the electric push rod 4 is electrically connected to the output end of the microcontroller inside the control panel 20. One end of the electric push rod 4 is connected to the outer wall of one end of the rack 5 through a bracket.

[0026] In use, the electric push rod 4 is set to drive the rack 5 to translate.

[0027] A vertical shaft 11 is rotatably mounted on the top of the support 6. A gear 12 is fixedly mounted on the outer wall of the vertical shaft 11. A turntable 7 is fixedly mounted on the top of the vertical shaft 11. A frame 8 is provided on the top of the turntable 7. Several columnar frames 9 are provided inside the frame 8. Each columnar frame 9 is provided with a columnar tube cavity 10. A lifting plate 19 is movably provided at the lower end of the columnar tube cavity 10. A micro motor 13 is installed inside the columnar frame 9 on one side of the columnar tube cavity 10. One end of the micro motor 13 extends into the interior of the columnar tube cavity 10 and is equipped with a first conical tooth 14. A second conical tooth 15 is rotatably mounted on the bottom of the columnar tube cavity 10 on one side of the first conical tooth 14. The second conical tooth 15 meshes with the first conical tooth 14. A lead screw 16 is fixedly mounted at the center of the top of the second conical tooth 15. A nut pair 17 is threaded on the outer wall of the lower end of the lead screw 16.

[0028] In use, the connecting rod 18 is positioned by setting the nut pair 17;

[0029] Limiting frames 21 are provided on both sides of the inner wall of the cylindrical tube cavity 10 below the lifting plate 19, and connecting rods 18 are provided on both sides of the outer wall of the nut pair 17. The end of the connecting rod 18 away from the nut pair 17 passes through the limiting frame 21 and is connected to the bottom end of the lifting plate 19.

[0030] In use, the movement range of the connecting rod 18 is limited by the setting of the limit bracket 21;

[0031] A control panel 20 is installed on the top of the base plate 1 on one side of the stand 6. The output terminal of the microcontroller inside the control panel 20 is electrically connected to the input terminal of the micro motor 13.

[0032] In this embodiment, several columnar frames 9 are first arranged, each with a columnar tube-holding cavity 10 inside, to space out several centrifuge tubes. Then, an electric push rod 4 drives a rack 5 to slide inside a limiting frame 3, causing the rack 5 to drive a vertical shaft 11 via a gear 12 to rotate at the top of a stand 6. This causes the vertical shaft 11 to drive a turntable 7 to rotate synchronously, allowing the angle of the stand 8 to be adjusted horizontally. Thus, the centrifuge tubes placed inside the stand 8 can be rotated and moved closer to personnel without them having to move. To facilitate the handling of centrifuge tubes, the micro motor 13 drives the first conical tooth 14 to rotate, which in turn drives the lead screw 16 to rotate slowly via the second conical tooth 15. Because the limiting frame 21 limits the movement of the connecting rod 18, the nut assembly 17 slides upward on the outer wall of the lead screw 16, so that the nut assembly 17 drives the lifting plate 19 to move upward via the connecting rod 18. This slightly lifts the centrifuge tubes placed inside the cylindrical tube cavity 10, making it easier to handle the centrifuge tubes and thus completing the use of the centrifuge tube rack.
