Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge rotor. Background Art

[0002] The centrifuge uses mass inertia to separate the components of a sample. In a high-speed rotating rotor, heavier components (such as solid particles or heavier liquids) are pushed to the outside of the rotor by centrifugal force, while lighter components (such as liquids) remain inside the rotor, effectively separating the different components in the mixture.

[0003] When using a centrifuge to separate and concentrate samples such as flavors, since the test tubes containing the samples are relatively thin, test tubes of different diameters need to be replaced before and after the centrifugation operation, which increases the number of experimental steps and seriously slows down the experimental efficiency.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0028] like Figure 1-Figure 4 As shown, in one embodiment, a centrifuge rotor includes: a rotor body 1, a locking assembly 3 and a fitting assembly 4. The rotor body 1 is used to place a test tube 2 to be centrifuged; the locking assembly 3 and the fitting assembly 4 are arranged on the side wall inside the rotor body 1, the locking assembly 3 is used to lock the middle of the test tube 2 to prevent the test tube 2 with a smaller diameter from shaking; the fitting assembly 4 is used to abut the neck and bottom of the test tube 2.

[0029] Furthermore, the rotor body 1 is provided with a plurality of placement cavities 11. Specifically, the placement cavities 11 are provided in a plurality of groups, and a locking groove 12 is provided on the inner wall of one side of the placement cavities 11, which extends to the top of the rotor body 1.

[0030] like Figure 1-Figure 4 As shown, in this embodiment, the locking assembly 3 includes a locking rope 31 and a clamping spring 32. The locking rope 31 is connected to the clamping spring 32 through the locking groove 12, and is fixed to one side of the top of the rotor body 1 after passing through the end of the clamping spring 32. The locking rope 31 is used to lock the end of the clamping spring 32. The locking degree of the clamping spring 32 can be adjusted by adjusting the locking rope to adapt to test tubes 2 of different diameters.

[0031] Specifically, the clamping spring 32 is C-shaped, and the end of the clamping spring 32 is placed toward the locking groove 12. A locking hole 321 is provided at the end of the clamping spring 32. The locking rope 31 passes through the locking hole 321 from below and then passes through the locking groove 12.

[0032] like Figure 1-Figure 4 As shown, in this embodiment, the bonding component 4 is arranged on the inner wall of the placement cavity 11 , and the bonding component 4 includes a first buffer layer 41 and a second buffer layer 42 .

[0033] Furthermore, the first buffer layer 41 is arranged at the top of the placement cavity 11, and an annular convex strip is arranged in the middle thereof. When the test tube 2 is inserted into the placement cavity 11, the annular convex strip is recessed inwards to facilitate the passage of the test tube 2; the second buffer layer 42 is arranged at the bottom of the placement cavity 11, and its material is sponge, which is rapidly compressed when the bottom of the test tube 2 contacts it to provide buffering. Specifically, the clamp spring 32, the first buffer layer 41 and the second buffer layer 42 share the same axis.

[0034] Working principle: The middle part of the side wall of the placement cavity 11 inside the rotor body 1 is provided with a locking component 3, and the top and bottom fitting components 4. When in use, the test tube 2 is first placed in the placement cavity 11, the first buffer layer 41 fits the neck of the test tube 2, and the second buffer layer 42 fits the bottom of the test tube 2. Then the locking rope 31 locks and fixes the middle part of the test tube 2 through the locking hole 321 of the retaining spring 32. Therefore, test tubes 2 of different diameters can be placed in the placement cavity 11 without additional adjustment or adaptation. Compared with the traditional operation method, the present application reduces the number of times the test tube 2 is transferred, thereby significantly improving the efficiency and accuracy of the experiment.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
