Technical Field

[0001] The utility model relates to the technical field of experimental tools, in particular to a centrifugal separation device which is convenient for sampling. Background Art

[0002] A centrifuge is a common laboratory instrument used to separate different components in a mixture. It uses centrifugal force to separate solids and liquids in a sample. The principle of a centrifuge is to use rotational force to generate centrifugal force in the sample, thereby depositing heavy components to the bottom of the container and light components to the top. A centrifuge is usually driven by an electric motor, and the rotating part is called a rotor. The sample is placed in a sample tube or centrifuge tube in the rotor. When the centrifuge is started, the rotor begins to rotate, generating centrifugal force. The magnitude of the centrifugal force depends on the speed of the centrifuge and the radius of the rotor.

[0003] In the prior art: when using a centrifuge, a test tube needs to be inserted into the rotor of the centrifuge, and the required substances in the sample are separated by the high-speed rotation of the centrifuge. At the same time, in order to ensure the accuracy of sample separation, multiple identical samples are placed in the centrifuge, and multiple separation results are used to ensure accuracy. However, after each separation, the test tube needs to be removed separately, and another one needs to be removed after the inspection is completed, which is relatively troublesome.

[0006] As a preferred embodiment, a mounting groove matched with the protrusion is formed at the bottom of the rotor, the outer surface of the protrusion fits with the inner wall of the mounting groove, and the bottom of the rotor fits with the top of the centrifuge.

[0007] As a preferred embodiment, a limiting mechanism is provided on the top of the centrifuge, and the limiting mechanism includes a mounting rod fixedly mounted on the top of the centrifuge, and a circular ring block is fixedly mounted on the outer surface of the rotor.

At this time, the rotor is inserted into the inverted top block, and the rotor will move downward along the top block to connect with the rotating rod. When the rotor moves to the bottom, it is necessary to align the installation groove with the protrusion, and then make the two fit together. After the above operations are completed, the preliminary installation of the rotor is completed.

[0024] In this embodiment, firstly, a hollow block 206 is provided on the outer surface of the top block 205, and a spring is provided in the inner wall of the hollow block 206. The spring is fixedly connected to the sliding rod 207. When the spring is stressed, the extension rod 208 is extended to a position larger than the diameter of the rotating rod 202.

[0025] According to the above, during the installation process of the rotor 201, it is first necessary to press the extension rod 208, and the extension rod 208 will start to move toward the direction of the top block 205 until the extension rod 208 is smaller than the radius of the rotating rod 202. At this time, the rotor 201 is inserted onto the inverted top block 205, and the rotor 201 will move downward along the top block 205 to connect with the rotating rod 202. When the rotor 201 moves to the bottom, it is necessary to align the installation groove with the protrusion 204, and then make the two fit together. After the above operations are completed, the preliminary installation of the rotor 201 is completed.

[0026] like Figure 1-Figure 4 As shown, a limiting mechanism 3 is provided at the top of the centrifuge 1, and the limiting mechanism 3 includes a mounting rod 306 fixedly installed on the top of the centrifuge 1, a circular ring block 301 is fixedly installed on the outer surface of the rotor 201, an annular groove is provided on the outer surface of the circular ring block 301, and a limiting plate 302 is provided on the inner wall of the annular groove, a support plate 303 is fixedly installed on the top of the limiting plate 302, a bottom rod 304 is fixedly installed on the bottom of the support plate 303, a threaded sleeve 305 is slidably installed on the outer surface of the bottom rod 304, a circular groove matched with the bottom rod 304 is provided on the top of the mounting rod 306, the bottom end of the bottom rod 304 is fitted with the inner wall of the circular groove, a thread is provided on the outer surface of the mounting rod 306, and the inner wall of the threaded sleeve 305 is threadedly connected to the outer surface of the mounting rod 306.

At this time, the rotor 201 is inserted onto the inverted top block 205, and the rotor 201 will move downward along the top block 205 to connect with the rotating rod 202. When the rotor 201 moves to the bottom, it is necessary to align the installation groove with the protrusion 204, and then make the two fit together. After the above operation is completed, the preliminary installation of the rotor 201 is completed. After the preliminary installation of the rotor 201 is completed, the stability of the rotor 201 during operation is further ensured by the limiting mechanism 3. First, the limiting plate 302 needs to be placed in the inner wall of the annular block 301, and then the bottom end of the bottom rod 304 installed at the bottom of the support plate 303 must also fit with the inner wall of the circular groove. After this operation is completed, the threaded sleeve 305 is screwed to make the threaded sleeve 305 and the installation rod 306 threadedly connected to complete the final installation.

[0030] According to the above, the rotor 201 is separated from the centrifuge 1. When multiple test tubes need to be removed, the above operation is reversed to remove the rotor 201 and put it on the laboratory table. It is convenient and quick to remove samples from the centrifuge 1 multiple times without having to do so.
