Description

Technical Field

[0001] This utility model belongs to the field of PSYI crude product synthesis technology, and in particular relates to a centrifuge device for PSYI crude product synthesis. Background Technology

[0002] Crude PSYI synthesis refers to the initial synthesis process of phytoene synthase (PSY). Phytoene synthase is the first synthase in the carotenoid biosynthesis pathway, catalyzing the formation of phytoene from two molecules of GGPP (geraniylgeraniyl pyrophosphate). In plants, the phytoene synthase encoded by the PSY gene is one of the key rate-limiting enzymes in the carotenoid metabolic pathway, and its activity and expression level directly affect the amount of carotenoids synthesized. The number and expression characteristics of the PSY gene vary among different plants. For example, there is only one PSY gene in Arabidopsis thaliana, while multiple genes encode it in plants such as tomato, cassava, maize, and rice. Therefore, a centrifuge device specifically for crude PSYI synthesis is required.

[0003] Currently, Chinese Patent CN208161847U discloses a centrifuge device, which includes a rotating flange and a rotating drive mechanism. The rotating flange has multiple mounting slots for placing centrifuge tubes. The output shaft of the rotating drive mechanism is connected to the rotating flange and can drive the rotating flange to rotate coaxially. It also includes an angle detection mechanism for detecting the rotation angle of the rotating flange or the rotating drive mechanism, and a displacement detection mechanism for detecting the displacement of preset points on the rotating flange or the rotating drive mechanism relative to the displacement detection mechanism. The centrifuge device provided by this invention can accurately position centrifuge tubes, facilitating robot operation of the centrifuge device.

[0004] However, when using the above-mentioned device, the position of the mounting tank is fixed, making it difficult to adjust the position of the test tube. If the mixture is difficult to centrifuge, the centrifugation time will be long, making it difficult to centrifuge different mixtures and thus its practicality is poor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a centrifuge device for the synthesis of crude PSYI. Its advantages include: the ability to adjust the position of the test tubes, thus improving practicality.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A centrifuge for synthesizing crude PSYI includes a centrifuge body, a cover plate connected to the top of the centrifuge body by a locking hinge, a drive mechanism body fixedly connected to the bottom of the centrifuge body, a centrifuge mechanism disposed inside the centrifuge body, and a limit mechanism disposed on the centrifuge mechanism.

[0008] The centrifugation mechanism includes a centrifuge disc fixedly connected to the top of the drive mechanism body. The outer circumference of the centrifuge disc has several evenly distributed connection ports. The top outer wall of the centrifuge disc has adjustment ports that correspond one-to-one with the connection ports. The inner wall of the adjustment port and the inner wall of the connection port are fixedly connected to the same connecting rod. A test tube rack is fixedly connected to one side of the connecting rod, which allows for adjustment of the position of the test tubes, thereby improving practicality.

[0009] The top inner wall of the centrifuge disc is rotatably connected to several gears via bearings. A toothed plate is fixedly connected to one side of the connecting rod. The toothed plate forms a sliding fit with the inner wall of the connecting port. The toothed plate meshes with the gears. The toothed plate can be used to adjust the position of the connecting rod from the center of the centrifuge disc.

[0010] The bottom inner wall of the centrifuge disc is rotatably connected to a toothed ring via a bearing. The outer ring of the toothed ring meshes with a gear, and the toothed ring allows for adjustment of the position of the test tube rack.

[0011] The bottom inner wall of the centrifugal disc is rotatably connected to a rotating shaft via a bearing. Rotating teeth are fixedly connected to the surface of the rotating shaft. The rotating teeth mesh with the inner ring of the toothed ring. The arrangement of the rotating teeth allows the toothed ring to rotate.

[0012] The limiting mechanism includes a rotating block fixed to the top of the rotating shaft. The edge of the rotating block has several evenly distributed limiting openings. The inner wall of the limiting opening is slidably connected to a limiting rod. The limiting rod is hinged to the top outer wall of the centrifuge disc. The setting of the limiting rod can make the position of the test tube rack fixed and stable.

[0013] The limiting rod is located between the center of the rotating block and the center of the centrifugal disk, which can prevent the limiting rod from separating from the limiting port.

[0014] A limiting spring is fixedly connected to one side of the limiting rod. The limiting spring is fixed to the top outer wall of the centrifugal disc. The limiting spring ensures the limiting operation of the rotating block.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This centrifuge device for synthesizing crude PSYI can rotate a gear ring when the rotating gear rotates through an adjustment mechanism. The rotation of the gear can move the gear plate, allowing the connecting rod to slide within the inner walls of the connecting port and the adjustment port, thus adjusting the position of the test tube rack. Therefore, the position of the test tubes can be adjusted, thereby improving its practicality.

[0017] 2. The centrifuge device for synthesizing crude PSYI has a limiting mechanism that allows the limiting rod to rotate into the inner wall of the limiting port. After the position of the test tube rack is adjusted, the rotating block can be fixed. The elastic force of the limiting spring can apply pressure to the limiting rod, so that the limiting rod can be placed stably in the limiting port. Attached Figure Description

[0029] Several gears 7 are rotatably connected to the top inner wall of the centrifuge disc 2 via bearings. A toothed plate 8 is fixedly connected to one side of the connecting rod 4. The toothed plate 8 forms a sliding fit with the inner wall of the connecting port 5. The toothed plate 8 meshes with the gears 7. The toothed plate 8 can be subjected to force when the gears 7 rotate. At this time, the toothed plate 8 can slide in the inner wall of the connecting port 5. The movement of the toothed plate 8 can cause the connecting rod 4 to move, thereby adjusting the position of the connecting rod 4 from the center of the centrifuge disc 2.

[0030] The bottom inner wall of the centrifuge disc 2 is rotatably connected to a gear ring 9 via a bearing. The outer ring of the gear ring 9 meshes with the gear 7. The gear ring 9 can apply force to the gear 7 when rotating, which can cause the gear 7 to rotate and thus adjust the position of the test tube rack 3.

[0031] The bottom inner wall of the centrifugal disc 2 is rotatably connected to a rotating shaft 10 via a bearing. A rotating tooth 11 is fixedly connected to the surface of the rotating shaft 10. The rotating tooth 11 meshes with the inner ring of the toothed ring 9. The rotating tooth 11 can rotate when the rotating shaft 10 rotates, which in turn allows the toothed ring 9 to rotate.

[0032] The centrifuge device for synthesizing crude PSYI provided by this utility model can be used by simply covering the cover plate 16 and starting the drive mechanism body 17 to perform centrifugation for synthesizing crude PSYI. When adjusting the position of the test tube rack 3, rotating the rotating block 12 can cause the rotating gear 11 to rotate, the rotation of the rotating gear 11 can cause the gear ring 9 to rotate, the rotation of the gear ring 9 can cause the gear 7 to rotate, and the rotation of the gear 7 can cause the gear plate 8 to move. At this time, the connecting rod 4 can slide in the inner wall of the connecting port 5 and the adjusting port 6, and the position of the test tube rack 3 can be adjusted. Therefore, the position of the test tubes can be adjusted, thereby improving the practicality.

Between the center of the rotating block 12 and the center of the centrifugal disk 2, the limiting rod 14 can be made to fit against the inner wall of the limiting port 13 under the action of centrifugal force, which can prevent the limiting rod 14 from separating from the limiting port 13. A limiting spring 15 is fixedly connected to one side of the limiting rod 14. The limiting spring 15 is fixed to the top outer wall of the centrifugal disk 2. The setting of the limiting spring 15 can make the limiting rod 14 stable in the limiting port 13 under the action of elastic force, which can ensure the limiting operation of the rotating block 12.

[0035] The technical solution provided in this embodiment is as follows: the limiting rod 14 can be rotated into the inner wall of the limiting port 13. After the position of the test tube rack 3 is adjusted, the limiting rod 14 can be located in the limiting port 13. At this time, the rotating block 12 can be fixed, which can prevent the rotating shaft 10 from reversing and fix the position of the test tube rack 3. The elastic force of the limiting spring 15 can apply pressure to the limiting rod 14, which can make the limiting rod 14 stable in the limiting port 13.
