Detailed description of the invention
Embodiment 1
Be inverted a centrifugal centrifuge tube, it comprises centrifuge tube and is set in inner and coaxial with the centrifuge tube fixture of centrifuge tube.
As shown in Figure 1, centrifuge tube comprises one end open centrifuge tube body 1, and for the centrifuge tube lid 2 of closing openings.Centrifuge tube body 1 inwall is provided with positioning convex, and the support bar 7 namely upwards extended from bottom, for the position of stationary fixture.
As shown in Figures 2 and 3, fixture is assembled by sleeve pipe 3, filter membrane 4, sealing ring 5 and supporting seat 6, and two ends are opening.Filter membrane 4 is positioned in supporting seat 6, and sealing ring 5 is positioned on filter membrane 4, by snap-in structure compact siro spinning technology between supporting seat 6 and sleeve pipe 3.
As shown in Figure 4, the top of supporting seat 6, namely in the middle part of fixture, is provided with flange, and its external diameter is greater than fixture upper and lower two ends external diameter and coordinates with the inner wall sealing of centrifuge tube body.By this design, make fixture can forward or to be invertedly arranged in centrifuge tube body, and coordinating by flange and support bar 7, can the position of stationary fixture.
As shown in Figure 4, when fixture forward is placed, the bottom of supporting seat 6, is namely inverted bayonet socket 6-1, extend into support bar 7 position of centrifuge tube body 1; Now, the ground floor bayonet socket 2-1 on centrifuge tube pipe lid 2 can cover the opening on sleeve pipe 3 top by snap-in structure.
As shown in Figure 5, during fixture upside down, one end of sleeve pipe 3 is fixed on support bar, is inverted bayonet socket 6-1 and stretches out the centrifuge tube mouth of pipe; Now, the second layer bayonet socket 2-2 on centrifuge tube pipe lid 2 can be covered by snap-in structure and be inverted bayonet socket 6-1.
