Description
Technical Field
The utility model relates to a centrifugation technical field, concretely relates to centrifuge is with novel rotor that gets rid of flat.
Background
At present, centrifuges are in common use, and flat-swinging rotors are also in very many applications. It can have a plurality of hanging cups, can place a plurality of heparin tubes (or test tube) in every hanging cup, and the hanging cup can be swung flat automatically when the rotor rotates, and when the test tube that loads in the hanging cup was complete symmetry, no matter how much the rotational speed increase of rotor this moment, the hanging cup was all horizontal (hanging cup axial and rotatory axial vertical). However, for a suspension cup or when the test tube loading is asymmetric, the suspension cup will incline continuously along with the increase of the rotation speed, which is easy to cause accidents.
Therefore, a novel swing rotor is needed to solve the problem, so that the excessive inclination angle of the suspension cup caused by unreasonable test tube loading is avoided, and accidents are avoided.

In the use process of the traditional swing rotor, because the stop pin structure is not arranged, if the test tube in the swing rotor is loaded unreasonably or is not loaded completely correspondingly, the swing rotor causes an excessive inclination angle of a suspension cup, the suspension cup is easily scratched with an upper cover back plate of a centrifugal machine, and thus safety accidents are caused. The ubiquitous phenomenon of current flail rotor is: along with the increase of the rotating speed, the inclination angle of the suspension cup is gradually increased; and the utility model discloses a set up the transfusion cup groove on the transfusion cup to set up the stop pin, make the transfusion cup after throwing away the tie to certain angle, the stop pin through setting up disturbs the overturning movement of transfusion cup, prevents its transition slope, avoids safe risk, promotes the security of its use.
Further, a centrifugal separator is with novel rotor of getting rid of: the mounting grooves are 4, and the mounting grooves are symmetrically arranged along the circumferential direction of the rotor body.
Further, a centrifugal separator is with novel rotor of getting rid of: the number of the suspension cups is 4, and the suspension cups are arranged in the mounting grooves in a one-to-one correspondence manner.
Further, a centrifuge is with novel rotor that gets rid of: the number of the suspension cup shafts is 8; the suspension cup is axially symmetrically arranged on the rotor body and used for suspending the suspension cup.
Further, a centrifuge is with novel rotor that gets rid of: the number of the stop pins is 8; the stop pins are fixedly connected to the suspension cup shafts in a one-to-one correspondence manner.
The utility model has the advantages that:
(1) The utility model has simple structure design; the utility model adds a stop pin on the suspension cup shaft of the conventional swing rotor, and when the suspension cup normally operates, the stop pin does not work; when the suspension cup is overturned excessively, the stop pin can be in contact with the suspension cup groove to limit the suspension cup to be overturned continuously, so that accidents are avoided, and the safety is improved.
(2) The stop pin of the novel swing rotor designed by the utility model is fixedly connected on the suspension cup shaft, when the rotor body rotates, the suspension cup can be automatically swung and leveled, and the suspension cup can exceed the horizontal line to continue to incline sometimes due to the difference of test tube loading (incompletely symmetrical loading or unreasonable loading), but the excessive inclination of the suspension cup can cause the friction between the suspension cup and the upper cover of the centrifuge, thus easily causing accidents; consequently the utility model discloses to this problem of going out excessive slope easily of hanging glass, and designed this neotype rotor structure that throws away, solved the fault problem that the hanging glass probably causes because of excessive slope at rotatory in-process.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Example 1
As shown in fig. 1-3, a novel swing rotor for a centrifuge is characterized in that the swing rotor comprises: the test tube loading device comprises a rotor body 1, 4 suspension cups 2 for loading test tubes, 8 suspension cup shafts 3 and 8 stop pins 4; 4 mounting grooves 1-1 for mounting the suspension cup 2 are symmetrically arranged on the rotor body 1 around the circumference of the rotor body; the suspension cup shaft 3 is fixedly arranged in the mounting groove 1-1, and the suspension cup 2 is rotatably connected to the suspension cup shaft 3 in a suspension manner; a hanging cup groove 2-1 is arranged on the hanging cup 2 along the length direction; the stop pin 4 is connected to the suspension cup shaft 3, the stop pin 4 is located in the suspension cup groove 2-1, and the stop pin 4 is used for preventing the suspension cup 2 from being excessively inclined when the rotor body 1 rotates.
The utility model discloses a get rid of flat rotor: when the rotor body 1 rotates, the suspension cup 2 can be automatically swung flat, after the suspension cup 2 is swung flat, if the suspension cup 2 excessively inclines, the stop pin 4 can be in contact with the side wall of the suspension cup groove 2-1, the purpose of limiting the suspension cup 2 to continuously rotate is achieved by using the stop pin 4, further inclination of the suspension cup 2 can be avoided, and accidents are avoided.
Generally, the centrifugal machine swing rotor loading test tubes are symmetrical around the rotation axis of the suspension cup, and after the swing rotor rotates, the suspension cup is gradually swung under the action of centrifugal force; the greater the speed of rotation, the closer the cup is to horizontal (perpendicular to the rotor axis of rotation).
Unreasonable loading conditions can also occur in practical application: when an even number of test tubes are loaded, the test tubes can be symmetrically loaded in the hanging cup, and the problem that the hanging cup is excessively inclined due to the fact that the test tubes are symmetrically loaded cannot occur. When only one test tube is arranged or the test tube loading is asymmetric, the suspension cup can turn over when the rotor rotates at a high speed, the higher the rotating speed is, the more serious the turning is, the problem of excessive inclination is easy to occur, the scratch between the suspension cup and the upper cover of the centrifuge can be possibly caused, and accidents are easy to cause.
The novel swing rotor designed by the utility model adds a stop pin structure on the suspension cup shaft of the conventional swing rotor, and when the suspension cup normally operates, the stop pin can not work; when the suspension cup is overturned excessively, the stop pin can be in contact with the wall surface of the suspension cup groove to limit the suspension cup to be overturned continuously, so that accidents are avoided.
The above is that the preferred embodiment of the present invention is only used for explaining the present invention, and is not used for limiting the present invention. All obvious changes or variations led by the technical proposal of the utility model are still within the protection scope of the utility model.
