Description

Technical Field

[0001] The utility model relates to the technical field of centrifuges, in particular to a centrifuge for environmental detection with an anti-shake structure. Background Art

[0002] A centrifuge is an instrument that separates fractions of different density and molecular weight in a substance by causing an object to settle under the centrifugal force that simulates the earth's gravitational field when it rotates around a fixed axis. Centrifuges are often used in environmental testing to separate environmental testing samples.

[0003] According to the description of a low-speed centrifuge for environmental testing disclosed on the patent website (authorization announcement number: CN 213377245U), "The utility model discloses a low-speed centrifuge for environmental testing, including a low-speed motor, a centrifugal chamber and a test tube fixing device. The rotating shaft of the low-speed motor is provided with a centrifugal chamber, and the centrifugal chamber is provided with a test tube fixing device. The test tube fixing device includes a tube body, a nut, a screw, a plurality of test tube fixing mechanisms, a support and a plurality of slots. The upper end of the tube body is provided with a support, and the support is provided with a screw that can be rotatably installed and the lower part is located in the tube body. The screw is provided with a nut located in the tube body. The upper end of the test tube fixing mechanism can be rotatably provided with a support body fixedly connected to the tube body, and the lower end of the test tube fixing mechanism can be rotatably provided with an arm body. The tube body is provided with slots corresponding to the arm body. Compared with the prior art, it can adapt to test tubes of various diameters and can adjust the inclination of the test tube."

[0005] During use, the utility model can drive the nut to move by rotating the screw rod, and can use the arm body to drive the fixing mechanism to adjust the inclination of the test tube. However, in actual use, since the base of the device is directly connected to the low-speed motor and the test tube fixing device lacks support, the force is applied to the drive shaft of the motor, which will cause damage to the motor drive shaft over time, resulting in shaking during the centrifugation process. Therefore, it is necessary to improve an environmental testing centrifuge with an anti-shake structure to solve the above problems. Utility Model Content
