Description

Technical Field

[0001] This utility model relates to the field of centrifuge equipment technology, and in particular to a high-speed refrigerated centrifuge. Background Technology

[0002] High-speed refrigerated centrifuges are core separation equipment in fields such as biological experiments, clinical testing, and chemical pharmaceuticals. They generate strong centrifugal force through high-speed rotation while maintaining a low-temperature environment, enabling the rapid separation and purification of substances such as cells, nucleic acids, and proteins. Their core performance depends on the stable operation of the motor and the continuous operation of the refrigeration system.

[0003] In actual laboratory use, the variety of test tube sizes is common. However, the test tube clamping structure of traditional high-speed refrigerated centrifuges is often rigidly bound to the test tube rack; that is, one test tube rack can only accommodate test tubes of a single size. This design means that when processing samples of different sizes, the experimenter must first stop the machine, open the centrifuge door, manually disassemble the old test tube rack and replace it with a new test tube rack of the corresponding size. The whole process takes at least 3-5 minutes. For batch experiments or multiple control experiments, frequent replacement of test tube racks seriously slows down the experimental progress.

[0025] To make the technical solution of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Reference Figures 1-6 A high-speed refrigerated centrifuge includes a refrigerated centrifuge body 1, a test tube holder 2 fixedly connected to the rotor of the refrigerated centrifuge body 1, and a clamping seat 3 fixedly connected to the test tube holder 2; the clamping seat 3 is circumferentially arranged about the center of the test tube holder 2; a clamping assembly 4 is provided inside the clamping seat 3, and the clamping assembly 4 is symmetrically arranged about the horizontal center of the clamping seat 3; a cavity corresponding to the clamping assembly 4 is provided inside the clamping seat 3.

[0027] The clamping assembly 4 includes a clamping seat 41, and the inner bottom surface of the clamping seat 41 is fixedly connected to the inner bottom surface of the cavity of the clamping seat 3; both ends of the clamping seat 41 are provided with slots, and the inner wall surface at the bottom of the slot is fixedly connected to a rotating shaft; the clamping seat 41 is rotatably connected to an inclined block 42 through the rotating shaft; a support plate 43 is fixedly connected to the upper left end surface of the clamping seat 41, and a threaded rod 44 is connected to the support plate 43 by a bearing; a sliding column 47 is fixedly connected to the lower end surface of the support plate 43, and a moving block 45 is slidably connected to the support plate 43 through the sliding column 47.

[0028] The clamping base 41 is symmetrically arranged about the horizontal center of the clamping base 3; the tilting block 42 is symmetrically arranged about the horizontal center of the clamping base 41; the right end face of the moving block 45 is rotatably connected to the roller 46, and the right end face of the roller 46 is in contact with the left end face of the tilting block 42; the moving block 45 is provided with a threaded hole, and the moving block 45 is threadedly connected to the threaded rod 44 through the threaded hole; the lower end face of the sliding column 47 is fixedly connected to the inner bottom surface of the cavity of the clamping base 3; the support plate 43, the threaded rod 44 and the sliding column 47 are all symmetrically arranged about the horizontal center of the clamping base 41.

[0029] Specifically, by providing the clamping assembly 4, when it is necessary to clamp the test tube, the operator simultaneously rotates the turntable at the upper end of the threaded rods 44 on both sides of the clamping seat 41. Since the moving block 45 is threadedly connected to the threaded rod 44 through the threaded hole, and the moving block 45 is slidably connected to the support plate 43 through the sliding column 47, the rotation of the threaded rod 44 will drive the moving block 45 to move upward along the sliding column 47; the roller 46 on the right end face of the moving block 45 moves upward accordingly and presses the outer end face of the inclined block 42, causing the inclined block 42 to rotate around the rotating shaft in the slot of the clamping seat 41, and the two sides of the inclined block 42 rotate upward. The inner end of the inclined block 42 moves towards the center, thus clamping the test tube. At this time, the tension spring 48 on the support plate 43 is stretched and stores elastic potential energy. When it is necessary to remove the test tube, the turntable is rotated in the opposite direction. The threaded rod 44 drives the moving block 45 to move down along the sliding column 47. The squeezing force of the roller 46 on the inclined block 42 disappears, and the elastic force of the tension spring 48 pulls the inclined block 42 to rotate in the opposite direction around the axis to reset. The two inclined blocks 42 separate, and the test tube can be removed. Through this structural design, the test tube can be effectively clamped and released, and the operation is simple and quick.

[0030] Furthermore, a locking block is fixedly connected to the tilting block 42, and a tension spring 48 is fixedly connected to the locking block; the tail end of the tension spring 48 is fixedly connected to the inner end face of the support plate 43; a turntable is fixedly connected to the upper end face of the threaded rod 44; and a silicone pad is fixedly connected to the inner end face of the tilting block 42.

[0031] Specifically, by incorporating a tension spring 48, when the clamping assembly 4 is not in operation, the tension spring 48 uses its own elasticity to keep the two tilting blocks 42 separated, providing sufficient space for the insertion of the test tube. When the clamping assembly 4 is in operation, the tension spring 48 is stretched and deformed, and after the test tube is removed, it can quickly pull the tilting blocks back to their initial position, ensuring the reusability and stability of the clamping assembly 4. The silicone pad further optimizes the clamping effect. Its soft and elastic properties increase the friction with the outer wall of the test tube, preventing the test tube from sliding during centrifugation, and also avoid rigid compression that could damage the test tube, effectively protecting the safety of the test tube during high-speed centrifugation.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
