Furthermore, the included angle between each annular fin and the axial direction above the annular fin ranges from 45 degrees to 90 degrees.
Further, on the plug body with the ladder-shaped structure, each shoulder surface is an inclined surface which inclines upwards.
Further, the cock body is hollow structure.
Further, the bottom end of the plug body is arranged in a sealing mode.
Furthermore, the bottom of the plug body is of an arc-shaped structure.
Further, the bottom end opening and the sealed setting in top of cock body.
Furthermore, the cover body is of a hollow structure, a bump is integrally processed in the cover body, the bump is of a hollow structure with a closed top end and an open bottom end, and the bottom end of the plug body is open and the top end of the plug body is communicated with the inside of the bump.
Further, the number of the ring-shaped fins is at least two.
Compared with the prior art, the utility model has the following effects:
a plurality of annular grooves or annular convex ridges are processed on the outer circular surface of the cover body, so that the friction force of the clamping mechanism during clamping can be effectively increased. Through the annular fin that the diameter is reduced by last to lower in proper order, can be applicable to the cylindrical test tube of different diameters or conical test tube. The universality is better, and the sealing performance is better.
The cover body is used for clamping and is positioned outside the test tube; the plug body is positioned in the test tube; the annular fin is located between cock body and the test tube for sealed, through the deformation of fin promptly, play the sealed effect to the test tube.

Detailed Description
The first embodiment is as follows: the embodiment is described with reference to fig. 1 to 4, and the test tube cap suitable for test tubes with different diameters comprises a cap body 1 and a plug body 2 which are coaxially and fixedly connected into a whole from top to bottom, wherein the cap body 1 is of a cylindrical structure, a plurality of annular grooves 11 are formed in the outer circumferential surface of the cap body 1 along the circumferential direction, the plug body 2 is of a step-shaped structure, the cross section of the plug body 2 is circular, a plurality of annular fins 3 are fixedly arranged on the outer circumferential surface of the plug body 2, the annular fins 3 are sequentially arranged from top to bottom along the axial direction of the plug body 2, the outer diameters of the annular fins 3 are sequentially reduced, the annular fins 3 are fixedly arranged on the outer circumferential surface of a plurality of step sections of the plug body 2 correspondingly, and each annular fin 3 is horizontally or obliquely arranged upwards.
The cover body 1 is used for clamping and is positioned outside the test tube; the plug body 2 is positioned inside the test tube 100; the ring-mounted fin 3 is located between the plug body 2 and the test tube 100, and is used for sealing, namely, the fin deforms to play a role in sealing the test tube.
A plurality of annular grooves 11 or annular convex edges are processed on the outer circular surface of the cover body 1, so that the friction force of the clamping mechanism during clamping can be effectively increased. Through the ring dress fin 3 that the diameter reduces from top to bottom in proper order, can be applicable to the cylindrical test tube of different diameters or conical test tube. The universality is better, and the sealing performance is better.
When the fin located above deforms to seal the test tube, the adjacent fin below plays a role in positioning and guiding, and small-amplitude deformation may exist.
The number of the ring-mounted fins 3 may be one or more. The axial spacing between each adjacent two of the annular fins 3 may be the same or different.
The diameters of the roots of the fins are reduced from top to bottom in sequence.
The cover body 1 may be a hollow thin-walled structure or a solid structure. The hollow structure needs to have one side closed, can be the upper end, also can be the lower extreme.
The test tube cover of this application can use on any equipment that has the function of covering. And is also suitable for manual capping.
The included angle range of each annular fin 3 and the axial direction above the annular fin is 45-90 degrees.
On the plug body 2 with the ladder-shaped structure, each shoulder surface is an inclined surface which inclines upwards. By the design, the fins are convenient to deform when the test tubes with different diameters are adapted. So that the fins are tightly attached to the inner wall of the test tube, and the test tube is better sealed.
The plug body 2 is a hollow structure. So design, when sealing up different diameter test tubes, through hollow structure's cock body 2, its deformation of fitting with a contraceptive ring fin 3 of being more convenient for, and then guarantee the sealed effect of cock body 2 to the test tube.
The bottom end of the plug body 2 is arranged in a sealing way. So design, prevent under the prerequisite of revealing when the liquid that prevents in the test tube volatilizees and empties, prevent that the sample in the test tube from getting into the test tube lid, and be convenient for the washing sterilization in the test tube lid production process.
The bottom of the plug body 2 is of an arc-shaped structure. So design, the weakening is in test tube transportation, and the liquid sample in the test tube can also improve the direction type when stopping up the test tube lid to the impact of test tube lid, bottom circular arc structure.
The bottom end of the cock body 2 is open and the top end is sealed.
The cover body 1 is of a hollow structure, a bump 12 is integrally processed in the cover body, the bump 12 is of a hollow structure with a closed top end and an open bottom end, and the plug body 2 is provided with an open bottom end and a top end communicated with the inside of the bump 12.
