The utility model discloses a design of inside and outside test tube hole, the inlayer selects two kinds of test tubes staggered distribution that capacity is bigger, and the skin chooses for use the test tube that capacity is less and the staggered distribution of inlayer, can guarantee that rotor strength is higher, and the availability factor is better.
Description
Technical Field
The utility model relates to a rotor of laboratory centrifuge.
Background
The general centrifuge rotor adopts a multi-ring structure with staggered test tube holes in order to increase the number of test tubes, and the centrifugal force is different due to different centrifugal radiuses of the test tubes on the inner ring and the outer ring. When the rotor is used, the centrifugal difference between the inner circle and the outer circle can be caused, the centrifugal effect is directly influenced, and even the data are inaccurate. Meanwhile, the number of the test tube holes of the inner ring is smaller than that of the test tube holes of the outer ring, so that the total number of the test tube holes is not high, and the capacity of the rotor is limited.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a satisfy not unidimensional test tube and experiment on centrifuge, the utility model provides a novel equal radius centrifuge rotor, including the base plate, slope on the base plate and be equipped with a plurality of layers of test tube hole, the test tube hole of at least one deck has two kinds of above sizes, the center of test tube hole bottom arrives the distance at base plate center equals.
Preferably, the base plate is provided with two layers of test tube holes, namely an outer layer and an inner layer, the outer layer of test tube holes are provided with notches, and the notches are far away from the inner layer. The outer test tube hole adopts the breach structure, and the opening is outside, and the test tube hides in the test tube hole, can make things convenient for the operation of lower floor's test tube on the one hand, and on the other hand also alleviates the resistance of wind.
Further, the inner layer is provided with test tube holes of two sizes, namely a test tube hole I and a test tube hole II, and the test tube hole I and the test tube hole II are alternately arranged.
Preferably, in order to save space, the outer layer includes a plurality of groups of test tube holes, each group of test tube holes is two in number and consistent in size, and each outer layer of test tube hole is arranged in a gap between the first test tube hole and the second test tube hole.
Further, a rotor hole for installing a motor shaft is formed in the middle of the base plate.
Has the advantages that: 1. the test tube holes are in an inner and outer square mode, so that the centrifugal radii of the test tube holes in the inner layer and the outer layer are consistent;
2. this kind of inside and outside test tube hole's design, the inlayer selects two kinds of test tubes staggered distribution that capacity is bigger, and the skin chooses for use the test tube that capacity is less and the staggered distribution of inlayer, can guarantee that rotor intensity is higher, and the availability factor is better.
3. The centrifuge has three test tubes which can be used, and the application range of the rotor is greatly improved.
4. Outer test tube hole adopts the breach structure, and the opening is outside, and the test tube hides in the test tube hole, can make things convenient for the operation of inlayer test tube on the one hand, and on the other hand also alleviates the resistance of wind.

Detailed Description
Example 1
As shown in fig. 1, a novel equal-radius centrifuge rotor includes a base plate 1, wherein a plurality of layers of test tube holes are obliquely arranged on the base plate 1, at least one layer of test tube holes has at least two or more sizes, and the distance from the center of the bottom of the test tube hole to the center of the base plate 1 is equal (in the figure, R1-R2-R3). The base plate 1 is provided with two layers of test tube holes which are respectively an outer layer 2 and an inner layer, the test tube holes of the outer layer 2 are provided with notches 5, and the notches 5 are far away from the inner layer. The inner layer is provided with test tube holes of two sizes, namely a first test tube hole 3 and a second test tube hole 4, and the first test tube hole 3 and the second test tube hole 4 are alternately arranged. Outer 2 includes a plurality of groups of test tube hole, and every group test tube hole quantity is two and the size is unanimous, every outer 2 test tube hole sets up in the clearance department between test tube hole one 3 and test tube hole two 4. And a rotor hole 6 for mounting a motor shaft is formed in the middle of the base disc 1. The inlayer selects the crisscross distribution of two kinds of test tubes that capacity is than big, and the outer test tube that selects capacity to be less distributes with the inlayer is crisscross for use, can guarantee that rotor intensity is higher, and the availability factor is better.
The working principle is as follows: in the test tube hole was put into to the test tube, because the action of gravity, the test tube got into test tube hole bottom, because the center of test tube hole bottom arrives 1 central distance of basal disc equals, so the test tube hole of outer 2 is unanimous with the centrifugal radius of the test tube hole of inlayer, and the test tube hole opening part of outer 2 is equipped with breach 5, conveniently places and takes out, and the size in test tube hole is not of uniform size, satisfies not unidimensional test tube hole and tests.
