Therefore, a high-efficiency centrifuge is proposed to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a high-efficiency centrifuge, comprising a body 1, a transparent cover 4 hinged to the top of the body 1, the transparent cover 4 being opened by a hinge to the top of the body 1, and the transparent cover 4 being made of transparent acrylic material, thereby facilitating observation of the centrifuged material inside; a rotating seat 2 is rotatably connected to the inner wall of the body 1, and an tilting mechanism 3 is provided on the surface of the rotating seat 2;
[0033] Reference Figure 2 and Figure 3The tilting mechanism 3 includes a threaded rod 31, which is rotatably connected to the center of the top of the rotating seat 2. A threaded block 32 is threadedly connected to the surface of the threaded rod 31. An internal thread groove is formed on the inner side of the threaded block 32. By rotating the threaded rod 31, the threaded block 32 can move up and down on its surface thread. Multiple sets of internal thread grooves are formed on the surface of the sliding groove of the threaded block 32. The outer wall of the screw 33 is threadedly connected to the inner wall of the thread groove. By connecting the screw 33 to the surface of the threaded block 32, multiple positions of the sliding position of the slider 34 driving the hinge rod 35 can be limited. A sliding groove is formed on the surface of the threaded block 32. The inner wall of the sliding groove of the threaded block 32 is slidably connected to the slider 34. By moving the slider 34 up and down on the surface of the threaded block 32, the corresponding hinge rod 35 can push the material fixed by the corresponding clamping seat b6 and the limiting component 7 to tilt. Thus, when the whole is rotated, the tilt angle required for various materials can be adjusted.
[0034] Reference Figure 2 and Figure 3 The slider 34 has a through hole on its surface, and the inner wall of the through hole contacts a screw 33. A hinge rod 35 is hinged to the surface of the slider 34, and a clamping seat a5 is hinged to the end of the hinge rod 35 away from the slider 34. By moving the slider 34, the hinge rod 35 can push the corresponding clamping seat b6 and the limiting component 7 to rotate, thereby adjusting the centrifugal effect required for different materials. The surface of the rotating seat 2 has multiple sets of grooves, and the clamping seat a5 is rotatably connected to the rotating seat 2. The inner wall of the groove of seat 2 is rotated so that the up and down movement of the hinge rod 35 pushes the clamping seat a5 to tilt around the rotation center point. Two sets of guide rods 8 are fixedly connected to the surface of the clamping seat a5. The surface of the guide rods 8 is slidably connected to the clamping seat b6. By the mutual approach of the clamping seat b6 and the clamping seat a5, the material can be fixed between the two. The outer wall of the clamping seat b6 is in contact with the inner wall of the groove. The inner wall of the clamping seat b6 is provided with a limit component 7.
[0035] Reference Figure 2 and Figure 4 The limiting component 7 includes a wedge 71, which is elastically connected to the top of the inner wall of the clamping seat b6 via a return spring 72. One end of the return spring 72 is fixedly connected to the top of the outer wall of the wedge 71, and the other end of the return spring 72 is fixedly connected to the top of the inner wall of the clamping seat b6. The function of the return spring 72 is to automatically reset the wedge 71 at the bottom inclined surface, which is squeezed by the guide rod 8 slot and moved by the manual push of the push block 73. Two sets of wedges 71 are provided.
[0036] Reference Figure 4Two sets of wedges 71 are fixedly connected to the outer walls of the two sets of wedges 71. The wedges 71 are slidably connected to the inner wall of the clamping seat b6. The surface of the guide rod 8 is provided with a slot. The bottom end of the outer wall of the wedge 71 is engaged with the inner wall of the slot of the guide rod 8. The engagement between the two can fix the clamping seat b6 at multiple positions on the surface of the guide rod 8, thereby clamping the material. At the same time, the bottom end of the clamping seat b6 is provided with a protruding plate, and the bottom end of the clamping seat a5 is provided with a guide groove. When the material is fixed, the protruding plate will lift the material, and the protruding plate can move on the inner wall of the guide groove of the clamping seat a5.
[0037] Working principle: When it is necessary to adjust the inclination of the material during centrifugation, rotate the threaded rod 31. Since the threaded block 32 is threadedly connected to the threaded rod 31, the threaded block 32 will move up and down on the surface of the threaded rod 31. The movement of the threaded block 32 drives the slider 34 to move up and down in its groove. The movement of the slider 34 pushes the clamping seat a5 to tilt around the rotation center point through the hinge rod 35. The tilting of the clamping seat a5 will drive the guide rod 8 and the clamping seat b6 connected to it to tilt together, thereby realizing the adjustment of the inclination of the material. Furthermore, through the threaded connection between the screw 33 and the surface of the threaded block 32, multiple positions of the movement of a single set of sliders 34 driving the hinge rod 35 can be limited to ensure that the inclination is fixed. Thus, different inclinations required for centrifugation of different materials can be adjusted individually at the same time.
[0038] The material is placed between clamping seat a5 and clamping seat b6. Clamping seat b6 can be directly pushed to move on the surface of guide rod 8, so that the groove on the surface of guide rod 8 contacts the inclined surface at the bottom of wedge 71. This causes wedge 71 to move upward against the elastic force of return spring 72, moving clamping seat b6 closer to clamping seat a5. When it reaches the appropriate position, wedge 71 automatically resets under the action of return spring 72, and the bottom end of wedge 71 engages with the groove of guide rod 8, fixing the position of clamping seat b6 on the surface of guide rod 8, thereby clamping the material. The convex plate at the bottom of clamping seat b6 will lift the material, and the convex plate can move within the guide groove at the bottom of clamping seat a5, ensuring that the clamping process is flexible and stable.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
