Utility model content
The applicant is for above-mentioned existing issue, be studied improvement, a kind of centrifuge tube mounting structure for food samples pre-treatment instrument is provided, it can not only prevent centrifugal liquid in pipe splashing when centrifugal, also ensure the stability of centrifuge tube simultaneously, solved the problem of centrifuge tube movability.
The technical scheme that the utility model adopts is as follows:
For a centrifuge tube mounting structure for food samples pre-treatment instrument, comprise hollow centrifuge shield, in described centrifuge shield be provided for being threaded the internal thread of centrifuge tube end interior week, rod cover stretches in described centrifuge tube; Offer a pair of the first pilot hole in the periphery of described centrifuge shield, each the first pilot hole coordinates with one end of locating dowel, and the other end of described locating dowel connects back-up block;
The concrete structure of described rod cover is as follows:
Comprise disk and barred body that one connects, offer multiple the second pilot holes on disk, at the also one flange connector of periphery of described disk, the external diameter of described barred body is less than the aperture of centrifuge tube, also has the splash bar pilot hole for running through splash bar on described barred body.
Its further technical scheme is:
Described a pair of the first pilot hole is arranged symmetrically with centered by the center of circle of described centrifuge shield;
Described back-up block is triangle, offers respectively the skewed slot for locating dowel end is installed along two hypotenuses of described back-up block;
On described back-up block, also have for the fixing installing hole of rolling disc.
The beneficial effects of the utility model are as follows:
The utility model is simple in structure, easy to use, and the layout of rod cover makes the liquid in centrifuge tube when centrifugal be difficult for splashing, and has ensured the stability of centrifuge tube when centrifugal, prevents centrifuge tube shake. Utilize circular locating dowel to be connected with centrifuge shield and back-up block, and on back-up block, have skewed slot, the locating dowel that connects centrifuge shield is remained in skewed slot under high speed centrifugation state, centrifuge tube is installed good stability, be difficult for dropping, greatly improved centrifugal efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.
As shown in Figure 2 and Figure 3, a kind of centrifuge tube mounting structure for food samples pre-treatment instrument comprises hollow centrifuge shield 1, in centrifuge shield 1 be provided for being threaded the internal thread 101 of centrifuge tube 5 ends interior week, rod cover 6 stretches in centrifuge tube 5. Offer a pair of the first pilot hole 102 in the periphery of centrifuge shield 1, a pair of the first pilot hole 102 is arranged symmetrically with centered by the center of circle of centrifuge shield 1. Each the first pilot hole 102 coordinates with one end of locating dowel 3, and the other end of locating dowel 3 connects back-up block 2. Back-up block 2 is triangle, offers respectively the skewed slot 202 for locating dowel 3 ends are installed along two hypotenuses of back-up block 2. On back-up block 2, also have for the fixing installing hole 201 of rolling disc 4. As shown in Figure 1, rod cover 6 comprises the disk 605 and barred body 603 that one connects, at the also one flange connector 602 of periphery of disk 605, on disk 605, offer multiple for second pilot hole 601 affixed with upper displacement disc, the external diameter of barred body 603 is less than the aperture of centrifuge tube 5, also has the splash bar pilot hole 604 for running through splash bar 30 on barred body 603. Above-mentioned flange 602 is circular, the bottom of flange 602 contacts with the aperture end face of centrifuge tube 5, seal thus the hole of centrifuge tube 5, prevent the liquid splash in centrifuge tube 5 in centrifugal process, play sealing process, the external diameter of barred body 603 is less than the aperture of centrifuge tube 5 simultaneously, makes it not affect the centrifugal of centrifugal liquid in pipe, can also prevent that centrifuge tube 5 from shaking under the action of the centrifugal simultaneously, ensure the centrifugal stability of centrifuge tube 5.
Specific works process of the present utility model is as follows:
As shown in Figure 1, Figure 2 and Figure 3, centrifuge tube 5 is threaded by the external screw thread of end and the internal thread 101 of centrifuge shield 1, rod cover 6 is affixed with upper displacement disc by the second pilot hole 601 on disk 605, rolling disc 4 is connected with the output of servo control mechanism, servo control mechanism starts drive rolling disc 4 and rotates, the afterbody of centrifuge tube 5 is upturned gradually in rotation process, in the time that rolling disc 4 reaches maximum speed, each centrifuge tube 5 approaches level, makes the different separating substances of the interior proportion of centrifuge tube 5 by centrifugal force. Because making centrifuge tube 5, the layout of back-up block 2 and locating dowel 3 is difficult for dropping.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to basic structure of the present utility model in the situation that, the utility model can be done any type of amendment.
