Description
Technical field
The utility model relates to a kind of stabilization structure of medical centrifuge, specifically, relates to a kind of stabilization structure of medical centrifuge.
Background technology
Centrifuge is the machinery of component in the mixture utilizing centrifugal force separate liquid and solid particle or liquid and liquid.Centrifuge is mainly used in the solid particle in suspension or liquid to separate; Or by two kinds of density differences in emulsion, liquid immiscible again separately; Can also be used for getting rid of the liquid in wet solid, special hypervelocity channel separator can also be separated the admixture of gas of different densities; Utilize the solid particle of different densities or the granularity feature that sinking speed is different in a liquid, some sedimentation centrifuges also can carry out classification to solid particle by density or granularity.Medical centrifuge relates generally to blood and is separated, research, the research of DNA and the purification of medicine of virus.If but shake appears in centrifugal barrel in separating-purifying process, cause separating-purifying incomplete, affect final result, cause test failure, if entail dangers to life security when drug purification is serious.
Utility model content
The purpose of this utility model is the weak point overcoming above-mentioned conventional art, provides a kind of exocentric structure of medical stabilization.
The purpose of this utility model is reached by following technical measures:
A kind of stabilization structure of medical centrifuge, the power transmission shaft comprising centrifugal barrel and link together with this centrifugal barrel, ball is provided with bottom described centrifugal barrel, outside is provided with fixing bucket, centrifugal barrel periphery is provided with two annular stabilization grooves, and stabilization rooved face is provided with roller, and the far-end of roller is provided with adjusting rod, adjusting rod is provided with screw thread, and adjusting rod is fixed on fixing bucket by nut.Adopt two annular stabilization groove structures can effectively prevent from occurring swinging in the centrifuge course of work, affect separating-purifying effect.
Improve as one:
Angle between described roller is 120 °, and the angle between described ball is 120 °.
Described power transmission shaft is provided with bearing.Add the frictional force that upper bearing (metal) can reduce in drive axis process and between fixing bucket.
Owing to have employed technique scheme, compared with prior art, the utility model has the advantages that:
The utility model adopts at centrifugal barrel outer setting roller, roller is fixed on fixing bucket, this structure is utilized to prevent from shaking in the course of work with the stability improved in the centrifugal barrel course of work, centrifugal barrel and centrifugation apparatus can be combined into an entirety again, the sinking speed of particle in the powerful centrifugal force accelerating liquid utilizing centrifuge power transmission shaft High Rotation Speed to produce, opens the separating substances of sedimentation coefficient different in sample and buoyant density.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Detailed description of the invention
Embodiment: as shown in Figures 1 and 2, a kind of stabilization structure of medical centrifuge, the power transmission shaft 7 comprising centrifugal barrel 4 and link together with this centrifugal barrel 4, described power transmission shaft 7 is provided with bearing 9.Be provided with ball 6 bottom described centrifugal barrel 4, described ball 6 contacts with fixing bucket 1 bottom surface.The outside of centrifugal barrel 4 is provided with fixing bucket 1, and centrifugal barrel 4 periphery is provided with two annular stabilization grooves 5, and stabilization groove 5 surface is provided with roller 3, and roller 3 rotates along the annulus track of stabilization groove 5.The far-end of roller 3 is provided with adjusting rod 2, and adjusting rod 2 is provided with screw thread, and adjusting rod 2 is fixed on fixing bucket 1 by nut 8.
Angle between roller 3 is 120 °, and the angle between ball 6 is 120 ° of effects being subject to the roller 3 be fixed on fixing bucket 1 when bucket wall in centrifugal barrel 4 rotary course reduce in centrifugal barrel 4 course of work shake by the method.
In the present embodiment, power is passed to centrifugal barrel 4 by power transmission shaft 7, centrifugal barrel 4 is according to the rotating speed of setting and time High Rotation Speed, in centrifugal barrel 4 rotary course, ball 6 can reduce the frictional resistance between fixing bucket 1 and centrifugal barrel 4, and bearing 9 can reduce the frictional resistance between power transmission shaft 7 and fixing bucket 1, roller 3 rotates along annular stabilization groove 5, prevent centrifugal barrel 4 high-speed rotation process from shaking, nut 8 can also play regulating action, can regulate adjusting rod 2 as required.
