Detailed Description

The technical solution of the present invention will be further explained with reference to the accompanying drawings and embodiments.

The embodiment of the utility model provides a centrifuge, as shown in fig. 1, the centrifuge includes a base 1 and a rotator 2 installed on the base 1, the rotator 2 is a hexagonal cylinder, a plurality of tube cavities 21 are provided in the rotator 2, the rotator 2 of the hexagonal cylinder is collocated with six tube cavities 21, the diameter of the test tube 7 is smaller than the diameter of the tube cavity 21, therefore, the test tube 7 can easily slide in the tube cavity 21, in order to make the test tube 7 generate centrifugal force when rotating, the test tube 7 can not be put upside down to cause solution leakage, the axis of the tube cavity 21 and the axis of the rotator 2 form an included angle, and six tube cavities 21 are arranged around the axis of the rotator 2, referring to fig. 2 and fig. 3, a plurality of outlets 22 are provided on the side of the rotator 2, the outlets 22 are located at the lower end of the tube cavity 21, a stopper 31 is further slidably provided at the outlet 22, when the stopper 31 slides and blocks the outlet 22, the test, when the slider slides and opens export 22, test tube 7 then because the light roll-off of gravity, this sets up taking out of convenient test tube 7, improves centrifuge's work efficiency.

Furthermore, as shown in fig. 2 and fig. 3, a sliding slot 32 is further provided at the outlet 22, the stopper 31 is clamped in the sliding slot 32, the stopper 31 can easily slide in the sliding slot 32, the arrangement structure is simple, and the sliding slot 32 can limit the movement of the stopper 31, so as to prevent the rotating body 2 from throwing away the stopper 31 during rotation, thereby ensuring the safety of centrifugal operation.

Further, as shown in fig. 2 and fig. 3, the stopper 31 is provided with a locking hole 311, a counter bore 321 is provided at the bottom of the sliding slot 32, a top pillar 33 is locked in the counter bore 321, and a spring 34 is provided between the top pillar 33 and the bottom of the counter bore 321; when the stop block 31 blocks the outlet 22, the top column 33 passes through the clamping hole 311, which further facilitates the limit of the stop block 31, so that when the stop block 31 blocks the outlet 22, the stop block 31 is clamped by the top column 33 to the clamping hole 311, the stop block 31 is fixed at the outlet 22, and when the rotary body 2 rotates, the stop block 31 slides open to cause the test tube 7 to fly out, thereby increasing the safety of the centrifuge; and when taking out test tube 7, press the fore-set 33 and can slide off dog 31, make test tube 7 roll-off, equipment operation is simple and convenient, improves the work efficiency of centrifuge work.
