SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a centrifuge rotor adapter structure can carry on and realize the mixed centrifugation of two kinds of specification centrifuging tubes, practices thrift cost, the structure is nimble and stability is good.

To achieve the above object, the solution of the present invention is: a centrifuge rotor adapter structure comprises a hanging cup, an adapter and a rotor frame, wherein a rotor is arranged in the center of the rotor frame, a plurality of placing cavities are formed in the periphery of the rotor frame and are uniformly distributed around the rotor frame, and the hanging cup is placed in the placing cavities and is connected to the rotor frame in a shaft mode;

hang the cup and be equipped with the confession the opening that the adapter cooperation was put into, set up a plurality of macropore and aperture on the adapter, the macropore supplies big specification centrifuging tube to put into, the aperture supplies small specification centrifuging tube to put into, the macropore evenly arranges the middle part at the adapter, the macropore evenly arranges in macroporous both sides.

Preferably, the rotor frame is respectively provided with a protruding shaft on two sides of the inner wall of the placing cavity, the outer side walls of two sides of the hanging cup respectively form an inverted U-shaped groove, and the hanging cup is hung on the rotor frame from top to bottom through the cooperation of the inverted U-shaped groove and the protruding shaft.

Preferably, the large holes are uniformly distributed in the middle of the adapter in the column direction.

Preferably, the number of the placing cavities is four.

Preferably, the number of the large holes is three, and the number of the small holes is four.

Preferably, the center of the rotor frame is provided with a rotating hole for connecting the rotor.

After the scheme of the above is adopted, the utility model discloses the design has macropore and aperture, consequently, the mixed centrifugation of the centrifuging tube of compatible two kinds of specifications both can be simultaneously, need not to prepare two kinds of centrifuge, the mixed centrifugation of the centrifuging tube of single specification can be carried out again, save equipment expenditure, the structure is nimble and reliable, after rotor drive rotor frame rotates, because the macropore evenly arranges at the middle part of adapter, and the aperture evenly arranges in macroporous both sides, so the relative both sides bearing of adapter middle part bearing gets bigger, make the focus of adapter concentrate on the middle part, produce the equilibrium force during centrifugation, let the adapter more heavy steady, avoid the rotor atress uneven.

Description of reference numerals:

the centrifugal centrifuge comprises a hanging cup 1, an opening 11, an inverted U-shaped groove 12, an adapter 2, a large hole 21, a small hole 22, a rotor frame 3, a rotary hole 31, a placing cavity 32, a convex shaft 33, a large-specification centrifuge tube 4 and a small-specification centrifuge tube 5.

Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

The utility model provides a centrifuge rotor adapter structure, including hanging cup 1, adapter 2 and rotor frame 3, rotor frame's center is equipped with changes hole 31 and rotor (not shown in the figure), changes hole 31 and supplies the rotor to connect, rotor frame 3 sets up a plurality of all around and places chamber 32, in this embodiment the quantity of placing chamber 32 is four, makes overall structure more roundly, four place chamber 32 and evenly arrange around rotor frame 3, place the adapter 2 that chamber 32 corresponds and hang cup 1 quantity and also be four, every is placed chamber 32 and is corresponded one and is hung cup 1 and an adapter 2. The hanging cup 1 is placed in the placing cavity 32 and is coupled to the rotor frame 3, and the hanging cup 1 is provided with an opening 11 for the adapter 3 to be placed in a matching manner.

The adapter 2 is of a cylindrical structure. Offer a plurality of macropore 21 and aperture 22 on the adapter 2, macropore 21 supplies big specification centrifuging tube 4 to put into, aperture 22 supplies small specification centrifuging tube 5 to put into, macropore 21 evenly arranges in the middle part of adapter 2, and in order to further prevent to overturn, the macropore is to arranging evenly in the middle part of adapter to the row, aperture 22 evenly arranges in the both sides of macropore 21.

In order to make the hanging cup easy to assemble and disassemble when in use, the shaft joint of the hanging cup is designed to be a detachable structure, the structure is as follows, the two sides of the inner wall of the placing cavity 32 of the rotor frame 3 are respectively provided with a convex shaft 33, the outer side walls on the two sides of the hanging cup 1 respectively form an inverted U-shaped groove 12, during assembly, the hanging cup 1 is placed into the placing cavity 32 from top to bottom, the inverted U-shaped groove 12 on the hanging cup is correspondingly matched and hung on the convex shaft 33 on the inner wall of the placing cavity, so that the hanging cup 1 can rotate around the convex shaft 33, the operation process of the embodiment is simple and reliable, the application flexibility of the centrifugal machine can be improved, and the use efficiency of the equipment is improved.
