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.

Please refer to fig. 1 to fig. 3, which are a top view of the centrifuge tube rack 1 with easy loading, a schematic structural diagram of the clamping plate 2 and the connecting handle 3, and a schematic structural diagram of the tube sleeve 4 and the limiting sleeve 5. To facilitate the illustration of the specific construction, only one sleeve 4 and a stop collar 5 provided therein are depicted in fig. 1.

The centrifuge tube rack 1 convenient for filling comprises a clamping plate 2, a connecting handle 3, a tube sleeve 4 and a limiting sleeve 5. The clamping plate 2 is a circular flat plate, the central position of the clamping plate is vertically fixed with a connecting handle 3, and the periphery of the clamping plate is provided with 4 inner rings and 10 outer rings in a two-ring layout, and the number of the inner rings and the outer rings is 14 pipe holes 21.

The pipe hole 21 is a kidney-shaped hole, and one end is thinner and the other end is thicker. All the tube holes 21 are parallel in length direction, and the thick ends are close to the same side. The arrangement of the pipe hole 21 corresponds to the positions of 14 centrifugal holes in the centrifuge, and the circle center of the thin end is aligned with the circle center of the centrifugal hole.

The catch plate 2 is provided with a "U" -shaped engaging plate 22 along the edge of the thin end in each tube hole 21 at a side provided with the connecting lug 3 at an angle perpendicular to the catch plate 2. The connector tiles 22 are rounded on their inner walls adjacent their openings to facilitate insertion of the socket 4.

The pipe sleeve 4 is a circular pipe with one open end, and a circle of reinforcing edge 41 is arranged on the outer wall of the open end. The sleeve 4 is provided with a square notch 42 at the top, the depth of the notch 42 not exceeding the thickness of the reinforcing rim 41. The notch 42 is used for engaging with a chuck of the bullet-shaped centrifugal tube when the bullet-shaped centrifugal tube is inserted into the tube sleeve 4, so as to prevent the tube cover from being flicked due to sliding.

The sleeve 4 has an outer diameter slightly larger than the inner diameter of the narrow end of the aperture 21 and the reinforcing rim 41 has an outer diameter slightly larger than the diameter of the inner wall of the connector tile 22 so that the sleeve 4 can be snapped into the aperture 21 and the reinforcing rim 41 can be snapped into the connector tile 22. The two are matched and clamped to clamp the pipe sleeve 4, and meanwhile, the pipe sleeve 4 can be ensured to be vertical, so that the pipe sleeve can be conveniently inserted into a centrifugal machine.

The diameter of the butt end of the tube hole 21 is much larger than the outer diameter of the reinforcing rim 41. Since the clamp of the centrifuge tube will extend out of the notch 42 after placing the centrifuge tube in the tube sleeve 4, the whole including the extension of the centrifuge tube can be removed from the thick end of the tube hole 21.

The stop collar 5 comprises a filling section 51 and a sealing section 52. The filling section 51 has a cylindrical structure corresponding to the shape of the inner bottom of the pipe housing 4, and is inserted into and fills the inner bottom space of the pipe housing 4. The top end of the filling section 51 is slightly higher than the bottom of the notch 42, and is provided with a holding cavity 53 for holding a centrifuge tube on the top surface. The filling section 51 comprises a plurality of configurations, and the containing cavities 53 with different configurations are used for containing a plurality of centrifuge tubes such as 2.0ml, 1.5ml, 0.5ml and 0.2 ml.

The sealing section 52 is of a cylindrical configuration adapted to the inner wall of the sleeve 4, and has two rings of sealing rings 54 on the side walls and a handle 55 at the top. After the centrifuge tube is inserted into the receiving cavity 53, the sealing section 52 is covered to fill the entire space in the sleeve 4. The centrifuge tube is sealed and compressed by the sealing section 52, so that the contamination caused by the bouncing of the centrifuge tube in the centrifugation process is avoided.

When the centrifuge tube is used, the proper filling section 51 is selected to be inserted into the tube sleeve 4 to the bottom, the centrifuge tube to be processed is placed in the accommodating cavity 53 of the filling section 51, and the chuck of the centrifuge tube is clamped into the notch 42. The handle 55 is then held by hand to insert the sealing section 52 into the sleeve 4 to be tightly held.

The 14 prepared pipe sleeves 4 are respectively clamped into the thin ends of the pipe holes 21, the openings of the pipe sleeves 4 face upwards, the bottom of the reinforcing edge 41 is abutted against the top surface of the clamping plate 2, the side surface is abutted against the inner wall of the connecting plate 22, and the notches 42 face towards the direction close to the thick ends.

Finally, the connecting handle 3 is held by hand, and all the pipe sleeves 4 are inserted into the centrifugal holes of the centrifugal machine. After the clamping plate 2 is inserted, the connecting handle 3 is held by hand to move transversely, the pipe sleeve 4 is moved out from the thin end to the thick end of the pipe hole 21, and then the clamping plate 2 can be separated from the pipe sleeve 4.

And after the centrifugation of the centrifuge is finished, the operations are carried out reversely. The thick end of the pipe hole 21 is aligned with the pipe sleeve 4 and inserted, then the clamping plate 2 is transversely moved to clamp all the pipe sleeves 4 into the thin end of the pipe hole 21, and all the pipe sleeves 4 can be lifted out of the centrifuge.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
