Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of centrifuge, including rack 1, sealing cover 2, driving motor 12, centrifugation frame 3, sealing cover 2 are hinged in rack 1,
Rack 1 is equipped with centrifugal chamber 11, and driving motor 12 is arranged in rack 1, and 11 center of centrifugal chamber is equipped with support column 14, driving motor
Sample is vertically put into centrifuge tube when needing to carry out centrifugal work through support column 14 by 12 drive shaft 13, and centrifuge tube is solid again
Fixed to cover sealing cover 2 to centrifugation 3 both ends of frame, driving motor 12 starts, and makes to be centrifuged frame 3 and generates quick rotation, thus carry out from
Heart work.
13 end of drive shaft is equipped with the bearing 31 in axle center and 13 axis perpendicular of drive shaft, and bearing 31 is connected in centrifugation frame 3
The heart, centrifugation 3 one end of frame are rotatably connected to centrifugal seat 4, and centrifugation 3 other end of frame is rotatably connected to sinker 5, due to the work of bearing 31
With, centrifugation frame 3 can be carried out inclination flip centered on bearing 31, when centrifugation 3 both ends of frame do not have centrifuge tube placement, centrifugation frame 3 by
Weight in both ends is identical, so that being centrifuged frame 3 is able to maintain horizontality, bearing 31 can effectively reduce centrifugation 3 inclination flip of frame
When frictional force, after encountering can not carry out centrifuge tube respectively, will centrifuge tube be inserted into centrifugal seat 4 in be fixed, thus from
The weight of 4 one end of centrifugal seat of heart frame 3 is larger, generates inclination to 4 one end of centrifugal seat to be centrifuged frame 3, then water is poured into counterweight
It in seat 5, is constantly injected by water, the weight of sinker 5 constantly rises, to be centrifuged frame 3 again gradually to sinker 5 one
End inclination keeps horizontal until being centrifuged frame 3 again, is touching pressing pad 32, the generation for generating centrifugation frame 3 by a small margin is shaken again
