Description

Technical Field

[0001] The utility model relates to a centrifugal bowl assembly, in particular to a centrifugal bowl assembly with a clamp. Background Art

[0002] Blood is composed of multiple components, including red blood cells, white blood cells, platelets, plasma, etc. These components have different densities and sizes, so they can be separated by using the difference in centrifugal force. Centrifugal component separators based on the centrifugal principle are widely used in the fields of clinical medicine, blood disease research, gene research, cell culture, chemical science, etc.

[0003] The centrifugal bowl is one of the important components of the centrifugal component separator and is used to hold the separation container. The centrifugal bowl can be driven by a motor to rotate, and the rotating centrifugal bowl then drives the separation container held inside to rotate.

[0004] In the existing products, when loading the separation container into the separation bowl, only the lower part around the separation container is clamped into the centrifugal bowl, and there is still a gap between the upper part around the separation container and the centrifugal bowl. When the centrifugal bowl and the separation container rotate, vibration often occurs, generating vibration noise, affecting the use, and shortening the service life of the equipment. Content of the Utility Model

[0005] Aiming at the problems existing in the prior art, the utility model provides a centrifugal bowl assembly with a clamp, which can eliminate the gap between the upper part around the separation container and the centrifugal bowl, and further eliminate the rotation vibration and noise problems caused by the gap.

[0006] The technical solution adopted by the utility model is: a centrifugal bowl assembly with a clamp, including a centrifugal bowl, a clamp and an O-ring. The inner part of the centrifugal bowl is provided with an upper clamping groove and a lower clamping groove; the centrifugal bowl is a symmetric rotating body, used to hold the separation container and can be driven by a motor to rotate; the clamp is used to clamp the upper part around the separation container; the O-ring is used to clamp the lower part around the separation container.

[0007] Preferably, the upper clamping groove is annular and collinear with the rotation axis of the centrifugal bowl for installing the clamp.

[0008] Preferably, the lower clamping groove is annular and collinear with the rotation axis of the centrifugal bowl for installing the O-ring.

[0009] Preferably, the clamp has elasticity.

[0010] Compared with the prior art, the utility model has the following beneficial technical effects:

[0011] A centrifuge bowl assembly with a clamp provided by the utility model comprises a centrifuge bowl, a clamp and an O-ring. During operation, a separation container is loaded into the centrifuge bowl assembly with a clamp. The clamp can clamp the periphery of the upper part of the separation container to eliminate the gap between the periphery of the upper part of the separation container and the centrifuge bowl. The O-ring can clamp the periphery of the lower part of the separation container, eliminating the gap between the periphery of the lower part of the separation container and the centrifuge bowl, effectively solving the problem of gap vibration, eliminating the resulting noise, and improving the service life of the equipment.

[0017] The following further describes the present utility model in detail with reference to the drawings, which is an explanation rather than a limitation of the present utility model.

[0018] Please refer to Figures 1-4 , the present utility model provides a technical solution: a centrifuge bowl assembly with a clamp, including a centrifuge bowl 1, a clamp 2 and an O-ring 3. The centrifuge bowl 1 is internally provided with an upper clamping groove 1-1 and a lower clamping groove 1-2. The centrifuge bowl 1 is used for clamping a separation container. The centrifuge bowl 1 is a symmetric rotating body and can be rotated by a motor. The clamp 2 is installed in the upper clamping groove 1-1 for clamping the periphery of the upper part of the separation container. The O-ring 3 is installed in the lower clamping groove 1-2 for clamping the periphery of the lower part of the separation container.

[0019] When the separation container is loaded into a centrifuge bowl assembly with a clamp of the present invention, the upper periphery of the separation container will squeeze the clamp 2, and the lower periphery of the separation container will squeeze the O-ring 3; under the squeezing force of the separation container, the clamp 2 will deform to generate a reaction force, thereby clamping the upper periphery of the separation container and eliminating the gap between the upper periphery of the separation container and the centrifuge bowl 1; the O-ring 3 will deform to generate a reaction force, thereby clamping the lower periphery of the separation container and eliminating the gap between the lower periphery of the separation container and the centrifuge bowl 1. Therefore, the problems of gap vibration and noise are solved, and the service life of the equipment is also improved.

[0020] The above content is only to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the claims of the present invention.
