Description

Technical Field

[0001] The utility model belongs to the technical field of cell centrifuges, in particular to a laboratory cell centrifuge. Background Art

[0002] Laboratory cell centrifuges are essential equipment for research and production in fields such as biology and medicine. They separate substances using the centrifugal force generated by a rotating rotor. Centrifuges simulate the Earth's gravitational field, causing objects to undergo sedimentation, thereby separating substances of varying densities and molecules. They are widely used in laboratories in the chemical, food, pharmaceutical, and environmental protection sectors. Different types of centrifuges are used depending on the particle size and properties of the substances being separated. For example, high-speed or ultracentrifuges are typically used for separating tiny particles such as cells and viruses.

[0003] In contrast, Chinese patent publication number CN208695287U discloses a novel laboratory cell centrifuge comprising a body, a drive motor, a rotating shaft at the output end of the drive motor, a turntable fixedly mounted on the upper end of the rotating shaft, and multiple groups of accommodating cavities evenly arranged on the turntable. The accommodating cavities are arranged in a circular tubular shape. A sleeve is sleeved on the rotating shaft, the lower end of the sleeve is fixedly connected to the body, and a lifting disk is sleeved on the sleeve and slidably connected. The upper end of the lifting disk is provided with multiple groups of top blocks corresponding to the accommodating cavities, and the lower end of the lifting disk is provided with a pneumatic lifting mechanism, the lower end of which is fixedly connected to the body. This makes it easy to remove the sampling tube after centrifugation and prevents the sampling tube from tilting and falling due to instability. The structure is simple and the use effect is good.

[0004] However, the above patented test tube can only be in one of the following states: tilted or upright, with a fixed rotation radius and a fixed centrifugal force. Moreover, if it is tilted, it will seriously affect the convenience of removal, so a new device needs to be designed. Utility Model Content

The rotating shaft 205 is connected to the cantilever frame 204 by bearings; the test tube 4 is inserted into the supporting ring 206. Under the action of gravity, the supporting ring 206 supports the test tube 4 upright. The motor 201 drives the rotating frame 203 to rotate through the transmission shaft 202, so that the cantilever frame 204 drives the supporting ring 206 and the test tube 4 to rotate through the rotating shaft 205. Under the action of centrifugal force, the cantilever frame 204 supports the rotating shaft 205 to rotate, causing the supporting ring 206 supporting the test tube 4 to tilt, thereby increasing the rotation radius and enhancing the centrifugal force.

Cover the chassis cover 105 so that the sealing cover 106 seals the accommodating chamber 104 of the main chassis 103. The motor 201 drives the rotating frame 203 to rotate through the transmission shaft 202, so that the cantilever frame 204 drives the supporting ring 206 and the test tube 4 to rotate through the rotating shaft 205.
