Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube rack technology, specifically an adjustable centrifuge tube rack. Background Technology

[0002] Centrifuge tubes are common consumables used in laboratories for centrifugation operations. They are mainly used to hold liquid samples and separate different components (such as cells, proteins, and nucleic acids) in the sample by centrifugal force when the centrifuge rotates at high speed. Centrifuge tubes have a wide range of applications and can be used to separate cells, organelles, proteins, nucleic acids, blood stratification (serum / plasma), and urine precipitation. Centrifuge tubes usually need to be limited by centrifuge racks.

[0003] However, current centrifuge tube racks typically have multiple round holes on multi-layered boards, and the size of the holes is fixed, making the centrifuge tube racks unable to accommodate centrifuge tubes of different thicknesses. Furthermore, the spacing between the multiple boards of the centrifuge tube rack is fixed and does not have the function of adjusting the spacing, making the centrifuge tube racks unable to accommodate centrifuge tubes of different lengths. In view of this, we propose an adjustable centrifuge tube rack. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable centrifuge tube rack to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable centrifuge tube rack, including a shell, a fixing plate fixedly installed on the upper inner wall of the shell, a plurality of through holes opened on the top of the fixing plate, two opposing clamping blocks arranged inside each of the plurality of through holes, and a torsion spring arranged on the opposite side of each opposing clamping block, the two ends of the torsion spring contacting the clamping block and the fixing plate respectively.

[0006] Two slide rails are fixedly installed on the inner walls of both sides of the housing. A movable plate is slidably installed between the two slide rails. A bearing seat is fixedly installed in the middle of the lower side of the movable plate. Connecting rods are rotatably installed on both sides of the bearing seat. Nut pairs are rotatably installed on the other side of the two connecting rods. A threaded rod is threadedly connected between the nut pairs.

[0007] Preferably, two hinges are fixedly installed on both sides of the top of the outer casing, and a cover plate is fixedly installed between the other sides of two adjacent hinges.

[0008] Preferably, a magnet is fixedly installed on the right side of the cover plate on the left side, and a magnetic block is fixedly installed on the left side of the cover plate on the right side, corresponding to the magnet.

[0009] Preferably, each of the torsion springs has a mounting seat fitted on its inner wall, and the mounting seat is fixedly installed on the bottom of the fixing plate.

[0010] Preferably, each of the plurality of clamping blocks has a fixed shaft rotatably mounted on its upper end, and both ends are fixedly connected to a fixed plate.

[0011] Preferably, the top of the movable plate has multiple circular grooves, and the multiple circular grooves are respectively aligned vertically with multiple through holes.

[0012] Preferably, the threaded rod passes through both ends and is rotatably connected to the outer casing, the thread directions of the front and rear parts of the threaded rod are opposite, and a knob is fixedly installed at the front end of the threaded rod.

[0013] Compared with the prior art, this utility model provides an adjustable centrifuge tube rack with the following features:

[0014] Beneficial effects:

[0015] 1. This adjustable centrifuge tube rack allows the lower end of a centrifuge tube to be aligned with the through hole and inserted, causing the centrifuge tube to press against the clamps on both sides. At the same time, the clamps will flip and compress the torsion spring, increasing the gap between the two clamps to allow the centrifuge tube to pass through. The pressure applied to the clamps by the torsion of the torsion spring causes the two clamps to clamp the centrifuge tube tightly. The rack stops when the lower end of the centrifuge tube is inserted into the circular slot. Since the gap between the two clamps is adjustable, it can accommodate centrifuge tubes of different thicknesses.

[0016] 2. This adjustable centrifuge tube rack, by rotating the knob, will drive the threaded rod to rotate, and under the action of the nut pair and the threaded rod, the two nut pairs will move closer or further apart, and at the same time the included angle between the two connecting rods will change, so that the shaft seat at the other end of the connecting rod will push the movable plate upward or pull the movable plate downward to accommodate centrifuge tubes of different lengths.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please refer to Figure 1-5 An adjustable centrifuge tube rack includes an outer shell 19. A fixing plate 4 is fixedly installed on the upper inner wall of the outer shell 19. The top of the fixing plate 4 has multiple through holes 7. Each of the multiple through holes 7 has two opposing clamping blocks 15. Each opposing clamping block 15 has a torsion spring 14 on its opposite side. The two ends of the torsion spring 14 contact the clamping block 15 and the fixing plate 4, respectively.

[0030] Two slide rails 10 are fixedly installed on the inner walls of the outer casing 19 on both sides. A movable plate 9 is slidably installed between the two slide rails 10. A bearing seat 16 is fixedly installed in the middle of the lower side of the movable plate 9. Connecting rods 11 are rotatably installed on both sides of the bearing seat 16. Nut pairs 17 are rotatably installed on the other side of the two connecting rods 11. A threaded rod 18 is threadedly connected through the nut pairs 17. More specifically, the lower end of the centrifuge tube is aligned with the through hole 7 and inserted. The centrifuge tube then presses against the clamps 15 on both sides. At the same time, the clamps 15 flip and compress the torsion spring 14, making the gap between the two clamps 15 larger, allowing the centrifuge tube to pass through. The pressure applied to the clamps 15 by the torsion of the torsion spring 14 makes the two clamps 15 clamp the centrifuge tube. The process stops when the lower end of the centrifuge tube is inserted into the circular groove 8. The bottom of the centrifuge tube can be supported by the movable plate 9. When encountering centrifuge tubes of different lengths, the knob 3 can be rotated. The knob 3 will drive the threaded rod 18 to rotate. Under the action of the nut pair 17 and the threaded rod 18, the two nut pairs 17 will move closer or further apart. At the same time, the included angle between the two connecting rods 11 will change, causing the shaft seat 16 at the other end of the connecting rod 11 to push the movable plate 9 upward or pull the movable plate 9 downward to accommodate centrifuge tubes of different specifications.

[0031] In this embodiment, two hinges 2 are fixedly installed on both sides of the top of the outer casing 19, and a cover plate 1 is fixedly installed between the other sides of two adjacent hinges 2. More specifically, by flipping the two cover plates 1 towards the middle, the two cover plates 1 are joined together, thus covering the top opening of the outer casing 19 and preventing dust from adhering to the centrifuge tube.

[0032] In this embodiment, a magnet 5 is fixedly installed on the right side of the left cover plate 1, and a magnetic block 6 is fixedly installed on the left side of the right cover plate 1, corresponding to the magnet 5. More specifically, the magnet 5 and the magnetic block 6 are attracted together by their attraction.

[0033] In this embodiment, each of the inner walls of a plurality of torsion springs 14 is fitted with a mounting seat 13, which is fixedly installed on the bottom of the fixing plate 4. More specifically, the mounting seat 13 has a limiting function for the torsion springs 14, and the two ends of the torsion springs 14 will respectively press the movable plate 9 and the clamping block 15, so that the clamping block 15 can clamp the outer wall of the centrifuge tube.

[0034] In this embodiment, each of the multiple clamping blocks 15 has a fixed shaft 12 rotatably mounted on its upper end, and both ends are fixedly connected to the fixed plate 4. More specifically, when the clamping blocks 15 are flipped, they will rotate around the central axis of the fixed shaft 12 as the center of rotation.

[0035] In this embodiment, the top of the movable plate 9 has multiple circular grooves 8, which are aligned vertically with multiple through holes 7. More specifically, when the lower end of the centrifuge tube abuts against the circular groove 8, the circular groove 8 can be used to limit the lower end of the centrifuge tube, thereby enhancing stability.

[0036] In this embodiment, the threaded rod 18 passes through both ends and is rotatably connected to the outer casing 19. The thread directions of the front and rear parts of the threaded rod 18 are opposite, and a knob 3 is fixedly installed at the front end of the threaded rod 18. More specifically, by rotating the knob 3, the threaded rod 18 will rotate, and under the action of the nut pair 17 and the threaded rod 18, the two nut pairs 17 will move closer or further apart, thereby adjusting the included angle between the two connecting rods 11.

[0037] In actual operation, when this device is in use, the two cover plates 1 are flipped in the middle to align with each other, covering the top opening of the outer shell 19 to prevent dust from adhering to the centrifuge tubes. Then, the magnets 5 and magnetic blocks 6 attract the centrifuge tubes together. The lower end of the centrifuge tube is aligned with the through hole 7 and inserted. The centrifuge tube then presses against the clamps 15 on both sides. At the same time, the clamps 15 flip and compress the torsion spring 14, increasing the gap between the two clamps 15 to allow the centrifuge tube to pass through. The pressure applied to the clamps 15 by the torsion of the torsion spring 14 causes the two clamps 15 to press against the centrifuge tubes. The centrifuge tube is clamped and stops when the lower end of the centrifuge tube is inserted into the circular groove 8. The bottom of the centrifuge tube is supported by the movable plate 9. When encountering centrifuge tubes of different lengths, the knob 3 can be rotated. The knob 3 will drive the threaded rod 18 to rotate. Under the action of the nut pair 17 and the threaded rod 18, the two nut pairs 17 will move closer or further away from each other. At the same time, the included angle between the two connecting rods 11 will change, so that the shaft seat 16 at the other end of the connecting rod 11 will push the movable plate 9 upward or pull the movable plate 9 downward. During the process of the movable plate 9 rising and falling, it will slide along the slide rail 10.

[0038] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
