Fig. 1 is the utility model discloses a schematic diagram of an embodiment of centrifuging tube, fig. 2 is the cross-sectional view of centrifuging tube A-A department in fig. 1, and fig. 3 is the enlarger of B department in fig. 2, and fig. 4 is the utility model discloses an embodiment's of centrifuging tube explosion picture, refer to fig. 1 to 4, the centrifuging tube includes body 10 and lid 20, and the lateral part of body 10 is equipped with 3 wedge archs 11 along 10 outer wall circumference distributions of body, is equipped with the joint portion 21 that corresponds with the protruding 11 of wedge on the lid 20, and joint portion 21 buckles downwards and the protruding 11 joints of wedge. By bending the clamping portion 21 of the cover 20 downward to be buckled on the wedge-shaped protrusion 11, the clamping portion 21 pulls the cover 20 downward to be buckled on the end surface of the tube 10 under the action of the wedge-shaped protrusion 11. Compared with the arrangement of 2 wedge-shaped bulges 11, the arrangement of 3 wedge-shaped bulges 11 has a larger part to be shared and tensioned by each wedge-shaped bulge 11, so that the problem of poor sealing is easily caused in the partial area in the process of connecting the cover body 20 and the pipe body 10; compared with 4 wedge-shaped protrusions 11, the sealing performance is better, but the clamping portion 21 and the wedge-shaped protrusions 11 which need to be buckled in the actual operation process are more than the 3 wedge-shaped protrusions 11, and more time is spent in the connection process. Therefore, the 3 wedge-shaped protrusions 11 have the advantages that the sealing performance between the cover body 20 and the pipe body 10 can be guaranteed, and an operator can conveniently and easily connect the cover body 20 and the pipe body 10 to form an integrated structure. The setting of wedge arch 11, compare in the protruding buckling structure with the rectangular channel of rectangular structure's rectangle, the setting of the chamfer plane 111 on the wedge arch 11 makes that operating personnel can be comparatively light in the in-service use with joint portion 21 joint on wedge arch 11. Specifically, the setting of the chamfer plane 11 on the protruding 11 of wedge makes the head end of the protruding 11 of wedge crescent to the tail end for at the in-process of pegging graft 11 of wedge with joint portion 21, the head end through the protruding 11 of wedge can guide joint portion 21, at first comparatively light carry out the initial connection with joint portion 21 and the protruding 11 head end of wedge, later joint portion 21 moves along the protruding 11 length direction of wedge under the effect of external force, carry out reliable connection with joint portion 21 and the protruding 11 of wedge at last.

Preferably, the bottom surfaces of the 3 wedge-shaped protrusions 20 are planar and located in the same plane, and the bottom surface of the wedge-shaped protrusion 11 can be used as a full-scale reference plane of the centrifuge tube for fixing the liquid level in the centrifuge tube. Compare in current one side only at the centrifuging tube set up the scale mark and carry out the constant volume, the full scale reference plane of centrifuging tube is regarded as to the bottom surface of wedge arch 11, and the plane at bottom surface place through 3 wedge arch 11 is regarded as the constant volume reference plane, can avoid the centrifuging tube because there is the slope when the constant volume, and the intraductal liquid level that observes through the unilateral appears the visual deviation for the inaccurate problem of constant volume.

Preferably, the pipe body 10 is made of hard materials, the cover body 20 is made of elastic materials or is connected with an elastic component, and the cover body 20 and the pipe body 10 are in interference connection, so that the cover body 20 can be elastically deformed in the process of being connected with the pipe body 10, the cover body 20 and the pipe body 10 can be tightly attached and connected to form an integrated structure, and the sealing performance between the cover body 20 and the pipe body 10 is guaranteed.

Preferably, the outside end of joint portion 21 is equipped with joint groove 211, joint groove 211 is connected with wedge arch 11, specifically, joint groove 211 is the rectangular channel, the outside end of wedge arch 11 is equipped with oblique cutting plane, oblique cutting plane is pegged graft in the rectangular channel, oblique cutting plane's setting, make at the in-process of being connected joint groove 211 with wedge arch 11, can play the guide effect to joint groove 211 through oblique cutting plane, so that operating personnel is quick with joint groove 211 and wedge arch 11, reliably, convenient be connected formula structure as an organic whole.

Fig. 5 is an exploded view of a second embodiment of the centrifuge tube of the present invention, fig. 6 is an enlarged view of C in fig. 5, referring to fig. 5 and fig. 6, the difference between the second embodiment and the first embodiment is that the clip groove 211 is a cylindrical hole, the outer surface of the wedge-shaped protrusion 11 is adapted to the cylindrical hole, and the outward end of the wedge-shaped protrusion 11 is provided with a beveling plane 111, and the beveling plane 111 is inserted into the cylindrical hole. The outer surface of the wedge-shaped protrusion 11 is formed in a cylindrical shape, which facilitates the coupling operation by an operator. Further, still be equipped with sealing washer 30 between lid 20 and body 10, sealing washer 30 joint is in recess 12 on the body 10 lateral wall to can with the inner wall butt of lid 20, so that form seal structure between lid 20 and the body 10, guarantee the sealing reliability between lid 20 and the body 10.

More, the sealing ring 30 can also be embedded in the cover body 20, and the sealing ring 30 is tightly attached to the end surface of the pipe body 10, or the outer wall of the pipe body 10, or the inner wall of the pipe body 10, so that the cover body 20 and the pipe body 10 can be reliably sealed.

The technical features of the embodiments described above can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
