Description

Technical Field

[0001] This utility model relates to a centrifuge for screening inflammatory tissue fluid from mastitis. Background Technology

[0002] A centrifuge is a mechanical device that uses centrifugal force to separate different components in a mixture. It is widely used in various fields such as chemical, pharmaceutical, food, and environmental protection. For example, in screening mastitis tissue fluid, a centrifuge can be used to process extracted tissue fluid samples. Centrifugation can remove impurities from the sample, resulting in a purer sample. When using a centrifuge to separate mastitis tissue fluid, the test tubes containing the fluid need to be placed into the test tube holder on the rotor. Since the test tube holders on the market are directly mounted on the rotor, disassembling and replacing the rotor is necessary for test tubes of different diameters, which is quite inconvenient. Utility Model Content

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a centrifuge for screening inflammatory tissue fluid from mastitis. By separating the rotor from the test tube trough, multiple sets of test tube holders of different specifications can be installed on the rotor to accommodate test tubes of different diameters.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge for screening mastitis tissue fluid, comprising a chassis, a drive motor mounted at the bottom of the chassis, and a rotor fixedly connected to the output shaft of the drive motor. The rotor has several mounting ports along its circumference, and clamping portions are provided on both sides of each mounting port. Test tube seats of different diameters are provided in each mounting port. Each clamping portion is provided with a clamping assembly for fixing the test tube seats. The clamping assembly includes an abutment rod and a return spring. The clamping portion is provided with a through groove for the abutment rod to extend and abut against the test tube seat. The test tube seat is provided with a positioning groove corresponding to the position of the abutment rod for it to extend into. The end of the abutment rod away from the test tube seat is provided with a flange. The return spring is installed between the clamping portion and the flange. The abutment rod, positioning groove, and through groove are anti-rotation fits.

[0005] As a further improvement of this utility model, the positioning groove is provided with a first guide surface and a second guide surface, the first guide surface is disposed above the second guide surface, and the first guide surface and the second guide surface are combined to form a convex shape.

[0006] As a further improvement of this utility model, a bolt for pressing the abutment rod is provided on one side of the clamping part.

[0007] As a further improvement of this utility model, the output shaft of the drive motor is provided with a tray, the rotor is sleeved on the output shaft and abuts against the tray, and the rotor is provided with a number of bolts that are fixedly connected to the tray.

[0008] As a further improvement of this utility model, a rib is provided between the clamping parts at adjacent mounting openings.

[0009] The beneficial effects of this invention are: installing test tube holders of different diameters on the rotor to improve the adaptability of the centrifuge; and the clamping assembly can quickly disassemble a single test tube holder without disassembling the entire rotor.

[0014] The present invention will now be described in further detail with reference to the embodiments shown in the accompanying drawings.

[0015] Reference Figure 1-3 As shown, a centrifuge for screening inflammatory tissue fluid from mastitis includes a casing 1, a drive motor 2 mounted at the bottom of the casing 1, and a rotor 3 fixedly connected to the output shaft of the drive motor 2. The rotor 3 has several mounting ports 4 along its circumference, and clamping parts 6 are provided on both sides of each mounting port 4. Test tube holders 5 of different diameters are provided within each mounting port 4. The use of test tube holders 5 with different diameters improves the centrifuge's adaptability and eliminates the need for repeated disassembly of the rotor 3. Each clamping part 6 is equipped with a clamping assembly for fixing the test tube holder 5. Each test tube holder 5 is individually fixed by the clamping assembly, allowing for individual disassembly of a single test tube holder 5 when necessary, without disassembling the entire rotor. 3. Disassembly is performed. The clamping assembly includes an abutment rod 7 and a return spring 8. The clamping part 6 is provided with a through groove for the abutment rod 7 to extend and abut against the test tube seat 5. The test tube seat 5 is provided with a positioning groove 9 for the abutment rod 7 to extend into. The end of the abutment rod 7 away from the test tube seat 5 is provided with a flange 10. The return spring 8 is installed between the clamping part 6 and the flange 10. Both ends of the return spring 8 are also fixed to the clamping part 6 and the flange 10 respectively. The return spring 8 is a contraction spring so that the abutment rod 7 can continuously apply pressure to the test tube seat 5 to clamp the test tube seat 5. The abutment rod 7, positioning groove 9, and through groove are anti-rotation fits. In this solution, the abutment rod 7 is rectangular.

[0016] The positioning groove 9 is provided with a first guide surface 11 and a second guide surface 12. The first guide surface 11 is positioned above the second guide surface 12. The first guide surface 11 and the second guide surface 12 combine to form a convex shape. The first guide surface 11 and the second guide surface 12 facilitate the removal and installation of the test tube holder 5. One side of the clamping part 6 is provided with a bolt for pressing the abutment rod 7. By providing a bolt for pressing the abutment rod 7 on the side, the stability of the abutment rod 7 in fixing the test tube holder 5 is further improved. The output shaft of the drive motor 2 is provided with a tray 13. The rotor 3 is sleeved on the output shaft and abuts against the tray 13. The rotor 3 is provided with several bolts that are fixedly connected to the tray 13. The tray 13 on the output shaft makes the installation of the rotor 3 more stable. A rib 14 is provided between the clamping parts 6 adjacent to the mounting port 4. The rib 14 is provided to improve the overall strength of the rotor 3 and prevent the clamping part 6 from cracking or breaking due to high load.
