[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described in the following with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0023] Reference Figure 1 As shown in a specific embodiment of the anti-spill structure, comprising: inner cover 1, outer cover 3 and envelope 4. The anti-spill structure described in the application is applied to a centrifugal tube. In the process of centrifugation of the centrifugal tube, the anti-spill structure prevents the corrosion reagent in the centrifugal tube from spilling out or the reagent in the centrifugal tube from emitting corrosive gas to corrode the centrifugal equipment.

[0024] The inner cover 1 is suitable for being screwed to one end of the tube body 2 provided with an opening. The outer cover 3 is arranged on the top surface of the inner cover 1. Specifically, the bottom surface of the outer cover 3 is heat-fusedly connected with the top surface of the inner cover 1. The outer periphery of the envelope 4 is sealingly connected to the outer periphery of the outer cover 3. The envelope 4 and the outer cover 3 can be connected by heat fusion. The envelope 4 has a first state of being downwardly turned to be sealingly wrapped around the outer periphery of the inner cover 1 and an opening end of the tube body 2, and a second state of being upwardly turned to expose the opening end of the tube body 2. The tube body 2 is suitable for storing corrosive reagents. The outer peripheries of the inner cover 1 and the outer cover 3 are both formed with stripes 6 arranged in a concave-convex interval along the vertical direction, so as to increase the friction and facilitate screwing. The tube body 2 is a transparent tube.

[0025] Further, in the first state of the envelope 4, the opening end of the envelope 4 is arranged downwardly beyond the opening end of the tube body 2. Further, in the first state of the envelope 4, the height of the opening end of the envelope 4 downwardly beyond the opening end of the tube body 2 is greater than the height of the inner cover 1.

[0026] Further, the envelope 4 is a soft envelope. The envelope 4 is an elastic member.

[0027] Further, at least one protruding member is arranged on the outer periphery of the envelope 4. The protruding member is suitable for driving the envelope 4 to be upwardly turned or downwardly turned by hand. Specifically, the protruding member is a rubber sheet 5. The edge of the rubber sheet 5 can be arc-shaped.

[0028] As Figure 1 shown, the application further provides a centrifugal tube, comprising the anti-spill structure.

[0029] Further, the centrifugal tube further comprises a tube body 2, and the anti-spilling structure is arranged at the opening end of the tube body 2.

[0030] In use, the inner cover 1 is screwed first, and then the soft package sleeve is sleeved on the opening end of the tube body 2. When the centrifugal tube is not used, the soft package sleeve can be turned to the upper surface of the inner cover 1 by pinching the rubber sheet 5 with hands. When the centrifugal tube is used, the inner cover 1 needs to be screwed first, and then the soft package sleeve is turned down to double-seal the opening end of the tube body 2, thereby effectively reducing the situation that the reagent is spilled during centrifugation.

[0031] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
