When centrifuge high speed rotates also easily by the sample spillage of the inside, easily produce danger.Existing centrifugal
Seal of tube effect is not ideal enough.
[summary of the invention]
The purpose of the present invention solves the problems of the prior art exactly, proposes a kind of high leakproofness centrifuge tube, energy
Centrifuge tube is enough made to have good sealing.
For achieving the above object, the present invention proposes a kind of high leakproofness centrifuge tube, including body, inner bottom,
Blocker ring, sealing lid, be fixed with an inner bottom in described body, forms an auxiliary between inner bottom and its bottom
Cavity, the inwall on described body top is fixed with a circle blocker ring, has a seal groove, institute in the middle part of blocker ring
Stating and offer female thread on inboard wall of tube body, female thread is positioned at above blocker ring, and described sealing is covered by block, consolidated
Fixed column and seal head composition, described fixing column top is fixed with block, and fixing column bottom is fixed with seal head,
There are the external screw thread matched with female thread, described seal head to match with seal groove on fixing post sidewall, seal
It is fixed with a circle elastic seal ring on head outer wall.
As preferably, described body is structure as a whole with inner bottom, and body and blocker ring are structure as a whole.
As preferably, described its bottom offers through hole, is filled with elasticity and fills out in the auxiliary cavity in body
Fill body.
As preferably, the truncated cone that described seal groove is big up and small down, the seal groove degree of depth is less than seal head
Highly.
As preferably, described inner bottom semicircular in shape, the diameter of inner bottom is identical with the diameter of body.
As preferably, described tube wall is provided with a slot tag, label on slot tag, label
Groove is positioned on the outer wall at auxiliary position, cavity place.
As preferably, described block is rounded, and block diameter is more than pipe diameter, and the edge of block is provided with
Some anti-skidding projections.
Beneficial effects of the present invention: the present invention covers by seal head is arranged on sealing, and fitted seal groove can
So that centrifuge tube has good sealing；The setting of elastic seal ring further increases the close of centrifuge tube
Feng Xing；The arranging of blocker ring can effectively prevent the liquid in centrifuge tube to be thrown out of in centrifugal process；In
The setting at the end makes centrifuge tube be not easily susceptible to the impact of external force equipped with the part of liquid, is effectively protected centrifugal
Pipe.
Inventive feature and advantage will combine accompanying drawing by embodiment and be described in detail.
[accompanying drawing explanation]
Fig. 1 is the front view of the present invention a kind of high leakproofness centrifuge tube.
In figure: 1-body, 2-inner bottom, 3-blocker ring, 4-seal lid, 10-through hole, 11-assist cavity,
12-elasticity obturator, 15-slot tag, 16-label, 19-female thread, 30-seal groove, 41-block, 42-
Fixing post, 43-seal head, 44-elastic seal ring, the anti-skidding projection of 45-, 49-external screw thread.
[detailed description of the invention]
Refering to Fig. 1, one high leakproofness centrifuge tube of the present invention, including body 1, inner bottom 2, blocker ring 3,
Seal lid 4, between being fixed with in described body 1 bottom an inner bottom 2, inner bottom 2 and body 1, form an auxiliary
Cavity 11, the inwall on described body 1 top is fixed with a circle blocker ring 3, has one close in the middle part of blocker ring 3
Sealing groove 30, described body 1 inwall offers female thread 19, and female thread 19 is positioned at above blocker ring 3,
The described lid 4 that seals is made up of block 41, fixing post 42 and seal head 43, and described fixing post 42 top is fixed
There is block 41, bottom fixing post 42, be fixed with seal head 43, fixing post 42 sidewall has and female thread 19
The external screw thread 49 matched, described seal head 43 matches with seal groove 30, fixing on seal head 43 outer wall
Having a circle elastic seal ring 44, described body 1 to be structure as a whole with inner bottom 2, body 1 and blocker ring 3 are
Integrative-structure, offers through hole 10 bottom described body 1, be filled with bullet in the auxiliary cavity 11 in body 1
Property obturator 12, the truncated cone that described seal groove 30 is big up and small down, seal groove 30 degree of depth less than seal
The height of 43, described inner bottom 2 semicircular in shape, the diameter of inner bottom 2 is identical with the diameter of body 1, described
Label 16 groove 15, label 16 on label 16 groove 15, label 16 it is provided with on body 1 outer wall
