Detailed Description

The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.

Referring to fig. 1 and 2, in order to disclose a protective sleeve for a centrifuge tube of the present invention, the protective sleeve comprises a protective tube 1 coaxially sleeved outside the centrifuge tube and having a circular cross section and a bottom cover 2 connected to a bottom surface of the protective tube 1, wherein an outer diameter of the bottom cover 2 is larger than an outer diameter of the protective tube 1; the outer wall of protection tube 1 is gone up and is equipped with buffering subassembly along the axial cover of protection tube 1. The bottom surface of the cushioning member is carried on the top surface of the bottom cover 2. Put into protection tube 1 with the centrifuge tube in, buffer assembly on protection tube 1 overcoat again, at the high-speed rotatory in-process of centrifuge, because buffer assembly contact collision centrifuge inner wall, reduce the impulsive force that the centrifuging tube itself received, protection centrifuging tube non-deformable is broken, prolongs the life of centrifuging tube.

Referring to fig. 2 and 3, in the present embodiment, the buffer assembly includes a plurality of buffer rings 3 connected end to end along the axial direction of the protection tube 1, and the buffer rings 3 may be made of plastic. The protection tube 1 is provided with a fixing component for fixing the buffer component. The fixed subassembly includes two connecting blocks 11 of symmetric connection on the outer wall of 1 bottom of protection tube, and connecting block 11 is the rectangle with 1 integrated into one piece of protection tube and connecting block 11's cross-section. Each connecting block 11 is provided with a positioning screw rod 4 in a penetrating mode, the positioning screw rods 4 sequentially penetrate through the bottom cover 2, the connecting blocks 11 and the buffer rings 3, and the end face of each buffer ring 3 is provided with a yielding hole 31 for the positioning screw rod 4 to pass through; the bottom surface of the buffer ring 3 close to the bottom cover 2 is provided with a clamping groove 5 for the clamping and embedding of the connecting block 11. The positioning screw rod 4 penetrates through the bottom cover 2 and the connecting block 11, the buffer ring 3 located at the lowest position is placed down, the clamping groove 5 is just aligned to the connecting block 11 and clamped in, and finally the buffer rings 3 with proper quantity are selected to be sleeved outside the protection tube 1 according to the size of the centrifugal tube, so that the application range of the buffer assembly is enlarged, and the applicability of the buffer assembly is enlarged.

Referring to fig. 1 and 2, in order to prevent the cushion ring 3 from moving along the length direction of the positioning screw 4 during high-speed rotation, a limiting component for limiting the axial movement of the positioning screw 4 along the protection pipe 1 is disposed at one end of the positioning screw 4 extending out of the topmost cushion ring 3. In this embodiment, spacing subassembly includes threaded connection in the spacing lantern ring 6 that positioning screw 4 stretches out 3 one ends of buffer ring, is equipped with the internal thread with positioning screw 4's external screw thread assorted on the inner wall of spacing lantern ring 6. The bottom surface of the bottom cover 2 is a round bottom or a conical bottom, and is suitable for centrifuge tubes with different bottom shapes.

The implementation principle of the embodiment is as follows: after the centrifuging tube is put into protection tube 1, will fix a position screw 4 and pass bottom 2 and connecting block 11 earlier, will be located the buffering ring 3 of below and put down again for draw-in groove 5 just in time aims at connecting block 11 card and goes into, according to the size of a dimension of centrifuging tube, selects the buffering ring 3 covers of suitable quantity to establish outside protection tube 1, thereby enlarges the application range of buffering subassembly, enlarges its suitability.

After the buffer ring 3 is sleeved and finished, the limiting sleeve ring 6 is rotated to the positioning screw rod 4, so that the limiting sleeve ring 6 abuts against the uppermost buffer ring 3, and the buffer ring 3 is prevented from moving along the length direction of the positioning screw rod 4 in the high-speed rotating process.

At the high-speed rotatory in-process of centrifuge, because buffer ring 3 contact collision centrifuge inner wall, reduce the impulsive force that centrifuging tube itself received, protection centrifuging tube non-deformable is broken, prolongs the life of centrifuging tube.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
