[0002] Centrifuge is a kind of laboratory equipment for detection, is widely used in each field, such as biomedical, chemistry, material science etc. Its working principle is to utilize centrifugal force and separate different components in mixture, to realize quick, efficient separation and purification.

[0003] The core component of centrifuge is a high-speed rotating rotor, and a plurality of sample tubes are arranged on the rotor. When the rotor rotates at high speed, the liquid in the sample tube is subjected to strong centrifugal force, and the component with greater density is pushed to the pipe wall, and the component with smaller density is left in the pipe center, and different density substances can be effectively separated by this way. In order to meet the demand of detecting a plurality of samples at a time, the sample tubes are placed in the placing frame, and then the placing frame is placed on the rotor, so that the number of sample tubes loaded on the rotor reaches enough, and the centrifugal operation is carried out uniformly.

[0004] However, when the rotor is transferred, the rotor and the placing frame need to rotate relatively during centrifugation, so the movable connection is usually used between the rotor and the placing frame, which causes the rotor and the placing frame to be easily loose.

[0005] Based on this, the utility model discloses a centrifuge fixed sample liquid mechanism for test to solve the above problems. UTILITY MODEL CONTENTS
