New description: [New technology belongs to the base] This creation is related to centrifuges, especially for a centrifuge that can be used in different diameter tubes. [Prior Art] In the course of biological and chemical experiments, it is often necessary to use a centrifuge to separate sediments from the test tubes to separate solids and liquids. However, the test tube rack provided by the traditional centrifuge can only install the test tube of the same diameter. If the tube diameter of the test tube is different, the same centrifuge or different test tube rack must be replaced and operated in batches. Not only does it take time for the experiment, (4) it also needs to prepare a variety of test tubes of different specifications, and the demand for the test tubes of different diameters, which will lead to the experiment.

[Embodiment] The following preferred embodiments are listed to illustrate the structure and function of the present invention. Referring to the first figure, a centrifugal machine (^, including a base (20), an upper cover (3 〇), a motor (40), a test tube rack (50), and a Micro switch (6〇). _ The base (20) has a receiving space (22) inside. _ The upper cover (30) is pivoted on the base (2〇) and above the base (2〇), with a downward projection The pressure-receiving portion (32) is fixed to the base (20) and located in the accommodating space (22) for use as a power source. Please refer to the second to third figures, the test tube rack (50) has a The connecting portion (52) is connected to a wing portion (54) 'the towel, the connecting portion (52) of the test tube rack (5G) and the motor (50), so that the test tube holder (50) is located at the base (20) and the upper cover (3) Between and can be rotated by the driving of the motor (30), the two wings (54) extend obliquely upward from the opposite sides of the connecting portion (52) and have a plurality of perforations of different aperture sizes (56). The apertures of the perforations (56) are arranged from the outside of the wing (54) of the test tube holder (5) to the inside of the wing (54) of the test tube holder (50), i.e., in a large to small arrangement, that is, The larger the aperture, the closer the perforation (56) is to the test tube Outside the wing (54) of the frame (5〇), the smaller the aperture (56), the closer to the inside of the wing (54) of the test tube holder (5〇). The micro switch (60) is fixed to the base (20). Located in the accommodating space (22), 4 M384709 is electrically connected to the motor (40), and can be pressed by the upper cover (30) when the upper cover (3 〇) is covered by the base (2 〇). Start the motor (3〇) against the top. The above is the detailed structure of the centrifuge (10). When using the centrifuge (10) of this creation, first open the upper cover (3〇), then follow the test tube ( 12) The diameter of the tube is placed in the appropriate perforation (56). After the tube (12) is placed, the upper cover (3〇) can be closed to the base (2〇). The pressing part (32) of the upper cover (30) will touch the micro switch (6〇), and the micro switch (6〇) will send a signal to start the motor (4〇), and the test tube rack (5〇) can be driven by the motor. (40) is driven by the rotation of the tube (12) by its own rotation. When the experiment is finished, 'just open the upper cover (10), and the pressing part (32) of the upper cover (10) leaves the micro switch (60) 'motor (10)) Will stop running and let the test tube rack ( 5〇) Gradually stop the rotation After the straight pipe rack (10) has completely stopped rotating, the test tube (12) can be taken out. In this way, the centrifuge (10) of the present invention allows the tubes of different diameters (12) to simultaneously achieve the effect of SI liquid separation 'not to replace the tube racks with different specifications', thereby saving experiment time and reducing the cost of experiment. purpose. The constituent elements disclosed in the foregoing embodiments are merely examples of the present invention, and the substitution or variation of the material effect components should also be covered by the scope of the patent application of the present application. 5 M384709 BRIEF DESCRIPTION OF THE DRAWINGS The first figure is a cross-sectional view of a preferred embodiment of the present invention.
