Detailed Description

Preferred embodiments of the present utility model are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are merely for explaining the technical principles of the present utility model, and are not intended to limit the scope of the present utility model.

The utility model provides a centrifuge tube support, which comprises a support frame and a cylinder 3.

The support frame comprises a lower support ring 21, an upper support ring 22, four first support rods 41 and four second support rods 42. The upper support ring 22 is located above the lower support ring 21, and the cylinder 3 is located between the upper support ring 22 and the lower support ring 21. Both ends of the first support bar 41 are welded to the upper support ring 22 and the lower support ring 21, respectively. The two ends of the second support tube are welded to the cylinder 3 and the opposite one of the first support rods 41, respectively, so that the cylinder 3 is integrally connected with the support frame.

The top of the cylinder 3 is provided with a rubber pad 8 for supporting the tip part of the bottom of the centrifuge tube body 1; the upper support ring 22 is used for being attached to and supported at the transition part of the cylindrical wall surface and the conical wall surface of the centrifuge tube body 1, namely, the centrifuge tube body 1 can be limited and the scale marks are not shielded. The lower support ring 21 is used for supporting the whole support frame, and the diameter of the lower support ring 21 is larger than that of the upper support ring 22 so as to improve stability.

The rubber pad 8 is a revolving body structure, and the lower surface of the rubber pad 8 is provided with a ring groove 82 for enabling the wall of the cylinder 3 to be clamped into the ring groove 82, so that the structural constraint between the cylinder 3 and the rubber pad 8 is more sufficient. The rubber pad 8 and the cylinder 3 are fixed more firmly by means of gluing. The middle part of the rubber pad 8 is a through hole which is communicated with the inner side and the outer side of the cylinder 3. The surface of the rubber pad 8 facing upwards is provided with a conical curved surface 81 for being attached to the conical wall surface of the bottom of the centrifuge tube body 1.

The scheme also comprises a piston 5, a connecting rod 6 and a handle 7. The piston 5 is disposed in the cylinder 3 and is adapted to the diameter of the inner wall of the cylinder 3. The handle 7 and the bottom of piston 5 are connected respectively at the both ends of connecting rod 6, and the cross section of connecting rod 6 sets up to the cross for improve anti deformability. Two limit sliding grooves 31 are arranged at the bottom of the cylinder 3, and two ends of the handle 7 are arranged in the limit sliding grooves 31.

When the centrifuge tube body 1 is located on the rubber pad 8, the handle 7 is pulled downwards, the piston 5 moves downwards together with the piston, a negative pressure environment is caused in the cylinder 3, the centrifuge tube body 1 is further tightly adsorbed on the rubber pad 8, after the handle 7 is separated from the limiting sliding groove 31, the handle 7 is limited to reset by the bottom end face of the cylinder 3 by rotating a certain angle, and the cylinder 3 is kept in the current state. At this time, the centrifuge tube body 1 and the whole centrifuge tube support are connected into a whole, the centrifuge tube support can be carried no matter how the centrifuge tube body 1 is moved, and the centrifuge tube can be placed on a table surface anytime and anywhere, so that the centrifuge tube support can be used more in aspects.

When the centrifuge tube body 1 is required to be separated from the centrifuge tube support, the handle 7 is rotated to enable the handle 7 to be opposite to the limiting chute 31, so that the piston 5 can move upwards under the action of air pressure, and the handle 7 can be pushed with the aid of fingers, and finally the air pressure environment in the cylinder 3 is basically consistent with or slightly different from the external environment, so that the centrifuge tube body 1 can be easily separated from the centrifuge tube support.
