Description

Technical Field

[0001] This utility model relates to the field of centrifuge rotor technology, specifically to a centrifuge rotor structure and a centrifuge. Background Technology

[0002] Because the robotic arm in the pretreatment system cannot adjust the force and angle for removing the centrifuge adapter according to the actual situation as a human hand, sometimes the basket is pulled out of the centrifuge along with the human basket when the basket's weight is too small and the robotic arm is not fully flexible.

[0003] Previous solutions included increasing the weight of the basket to increase inertia and prevent it from being pulled out, but this would increase the load on the rotor during centrifugal operation and increase the burden on the equipment; adding a special mechanism or making structural modifications, although this method could solve the problem to some extent, the process was complicated and could not be applied to different models of centrifuges, lacking versatility; and reducing the size of the adapter outlet to block it, although this method attempted to solve the problem through physical obstruction, the obstruction position was too far away, and the basket might not be able to return to its normal working position after a collision, which would affect the operating efficiency.

[0004] Therefore, existing technologies need further development. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and provide a centrifuge rotor structure and centrifuge to solve the technical problem in the related art that the centrifuge basket is easily taken out of the centrifuge along with the adapter when it is removed.

[0006] To achieve the above technical objectives, the present invention adopts the following technical solution: a centrifuge rotor structure is provided, comprising: a rotor body, on which a plurality of outwardly extending hanging arms are provided, and a first connecting portion is provided on both opposite sides of the end of the hanging arms; a basket, on both sides of the basket are provided a second connecting portion adapted to the first connecting portion, the basket being rotatably connected to the first connecting portion through the second connecting portion, and the basket having an opening for the material to be centrifuged to enter the basket; a limiting component, the limiting component protruding from the outer surface of the basket, the limiting component being located on the side of the second connecting portion away from the opening, and the limiting component being groundably abutting against the hanging arms.

[0007] Furthermore, the limiting components include two, with limiting components installed on opposite sides of the suspended platform.

[0008] Furthermore, the first connecting part includes a hook pin, and the second connecting part includes a mounting hole adapted to the hook pin, wherein the hook pin is rotatably connected to the mounting hole.

[0009] Furthermore, guide grooves are provided on both sides of the suspended platform. One end of the guide groove is located on the side of the suspended platform away from the opening, and the other end of the guide groove is connected to the mounting hole.

[0010] Furthermore, the guide groove includes a first guide groove and a second guide groove that are interconnected. The opening of the first guide groove is located on the side of the basket away from the opening. One end of the second guide groove is connected to the first guide groove, and the other end of the second guide groove is connected to the mounting hole. The width of the first guide groove is greater than the width of the second guide groove.

[0011] Furthermore, the limiting component includes a first limiting part and a second limiting part, which are respectively disposed on opposite sides of the first guide groove.

[0012] Furthermore, the suspended platform is provided with a first positioning hole and a second positioning hole, both of which are provided with internal threads.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] According to an embodiment of this utility model, a centrifuge rotor structure is provided. Please refer to [link / reference]. Figures 1 to 3 The system includes: a rotor body 1, on which several outwardly extending hanging arms 11 are provided, and on opposite sides of the ends of the hanging arms 11 are first connecting portions 12; a basket 2, on both sides of the basket 2 are second connecting portions 21 adapted to the first connecting portions 12, the basket 2 is rotatably connected to the first connecting portions 12 through the second connecting portions 21, and the basket 2 has an opening 22 for the material to be centrifuged to enter the basket 2; and a limiting component 3, which protrudes from the outer surface of the basket 2 and is located on the side of the second connecting portion 21 away from the opening 22, and the limiting component 3 and the hanging arms 11 are ground-compatible.

[0024] By setting a limiting component 3, when the basket 2 is lifted upwards along with the adapter 10 and other materials, the limiting component 3 will contact the hanging arm 11 and provide resistance, preventing the basket 2 from continuing to move upwards and thus preventing the basket 2 from being taken away from the working position. This limiting mechanism can effectively prevent the basket 2 from being taken out along with the adapter without adding extra complexity, improving the safety and reliability of the centrifuge and solving the technical problem in related technologies where the centrifuge basket is easily taken out of the centrifuge along with the adapter when it is removed.

[0025] In the centrifuge rotor structure of this embodiment, see... Figure 1The limiting component 3 includes two components, with limiting components 3 installed on opposite sides of the suspended platform 2. This provides a symmetrical limiting effect, which can provide balanced resistance when the suspended platform 2 is subjected to external forces (such as when the robotic arm removes the adapter), avoiding tilting or instability caused by unilateral force, and ensuring that the suspended platform 2 always remains in the correct working position.

[0026] In the centrifuge rotor structure of this embodiment, see... Figure 1 The first connecting part 12 includes a hook pin, and the second connecting part 21 includes a mounting hole adapted to the hook pin. The hook pin is rotatably connected to the mounting hole. In this way, the suspended platform 2 can rotate freely within a certain range. The design of the hook pin and the mounting hole simplifies the installation and disassembly process of the suspended platform 2. The connection can be completed simply by inserting the hook pin into the corresponding mounting hole, without complicated tools or steps, thus improving the efficiency of maintenance and replacement of parts.

[0027] In the centrifuge rotor structure of this embodiment, see... Figure 1 Guide grooves 24 are provided on both sides of the suspended platform 2. One end of the guide groove 24 is located on the side of the suspended platform 2 away from the opening 22, and the other end of the guide groove 24 communicates with the mounting hole. The guide groove 24 can guide the hanging pin to be accurately inserted into the mounting hole, providing a clear path for the hanging pin, ensuring that the hanging pin can smoothly enter and be correctly aligned with the mounting hole, simplifying the installation process of the suspended platform 2, and also limiting the movement range of the hanging pin to a certain extent, increasing the stability of the connection point, and better maintaining the position of the suspended platform 2 during centrifugation, avoiding displacement caused by vibration or other external forces.

[0028] In the centrifuge rotor structure of this embodiment, see... Figure 3 The guide groove 24 includes a first guide groove 241 and a second guide groove 242 that are interconnected. The opening 22 of the first guide groove 241 is located on the side of the suspended basket 2 away from the opening 22. One end of the second guide groove 242 is connected to the first guide groove 241, and the other end of the second guide groove 242 is connected to the mounting hole. The width of the first guide groove 241 is greater than the width of the second guide groove 242. This wider first guide groove 241 allows for easier initial insertion of the hanging pin, reducing operational difficulty and simplifying the installation and disassembly process of the suspended basket 2. The narrower width of the second guide groove 242 limits the movement range of the hanging pin, better maintaining the position of the suspended basket 2 during centrifugation and preventing displacement due to vibration or other external forces.

[0029] Specifically, an arc transition surface or an inclined transition surface is provided at the connection between the first guide groove 241 and the second guide groove 242 to facilitate the insertion of the hanging pin into the second guide groove 242.

[0030] Specifically, the suspended platform 2 includes a platform handle and a platform body. The mounting hole is located on the platform handle, and the limiting component 3 is located between the platform handle and the platform body to prevent the limiting component 3 from being installed too high. This prevents the platform 2 from being lifted too high when materials are taken out, which would cause the center of gravity of the platform 2 to become unstable and cause the platform 2 to tilt and shift. This ensures that the platform can return to its normal working position after being blocked.

[0031] In the centrifuge rotor structure of this embodiment, see... Figure 1 The limiting component 3 includes a first limiting part 31 and a second limiting part 32, which are respectively disposed on opposite sides of the first guide groove 241. Preferably, the first limiting part 31 and the second limiting part 32 are symmetrically disposed on opposite sides of the first guide groove 241, which can provide symmetrical limiting function for the suspended basket 2.

[0032] Specifically, the first limiting part 31 and the second limiting part 32 are symmetrically arranged on opposite sides of the first guide groove 241. When the material is taken out of the basket 2, it can prevent the basket 2 from being lifted too high, causing the hanging pin to enter the second guide groove 242, which would cause the basket 2 to tilt and shift. The first limiting part 31 and the second limiting part 32 are symmetrically arranged on opposite sides of the first guide groove 241, so that the basket can still return to the normal working position after being blocked, avoiding affecting the loading and unloading efficiency of the material, keeping the position of the basket 2 as fixed as possible, and improving the reliability of the centrifuge.

[0033] In the centrifuge rotor structure of this embodiment, see... Figure 3 The suspended platform 2 has a first positioning hole 251 and a second positioning hole 252. Both the first positioning hole 251 and the second positioning hole 252 are provided with internal threads, and both the first limiting part 31 and the second limiting part 32 are provided with external threads. The first limiting part 31 is threadedly connected to the first positioning hole 251, and the second limiting part 32 is threadedly connected to the second positioning hole 252. In this way, by providing the first positioning hole 251 and the second positioning hole 252, the positioning and installation of the first limiting part 31 and the second limiting part 32 can be achieved.

[0034] In some embodiments, the first limiting part 31 and the second limiting part 32 are blocking screws, which have a simple structure, low modification cost of the basket 2, no strict requirements on the weight of the basket 2, and hardly increase the extra weight of the basket 2, thus reducing the load borne by the rotor during centrifugal operation.

[0035] In some embodiments, the basket 2 is first assembled onto the rotor body 1, so that the pins on the hanging arm 11 enter the guide grooves 24 on both sides of the basket 2. Then the basket 2 is moved so that the pins are inserted into the mounting holes, and then the first limiting part 31 and the second limiting part 32 are installed into the first positioning hole 251 and the second positioning hole 252, thus completing the assembly of the basket 2.

[0036] In this embodiment, the centrifuge includes the centrifuge rotor structure described above.

[0037] When the centrifuge rotor structure of this embodiment is applied to a centrifuge, when the adapter 10 and other materials are taken out of the basket 2, as the basket 2 is lifted upward along with the adapter 10 and other materials, the limiting component 3 will contact the hanging arm 11 and provide resistance. The limiting component 3 will prevent the basket 2 from continuing to move upward, thereby preventing the basket 2 from being taken away from the working position. This limiting mechanism can effectively prevent the basket 2 from being taken out along with the adapter without increasing the extra complexity of the centrifuge, thereby improving the safety and reliability of the centrifuge and solving the technical problem in related technologies that the centrifuge basket is easily taken out of the centrifuge along with the adapter when it is taken out.

[0038] In the centrifuge of this embodiment, there are no strict requirements on the weight of the basket 2 and almost no additional weight is added, thereby reducing the load on the rotor during centrifugation. The modification can be achieved simply by preparing positioning holes and blocking screws on the basket 2, which is simple to operate and has strong universality. In addition, this design can also ensure that the basket 2 can be corrected in time and return to the normal working position after being blocked, ensuring the continuity and stability of equipment operation and improving the overall working efficiency and reliability of the centrifuge.
