Description
Technical field
The utility model relates to a kind of laboratory apparatus, specifically, relate to a kind of test tube.
Background technique
In reality, widely used test tube includes with cover and not with cover, wherein the tube body and test tube cap of test tube with cover are all
Separated, use is pretty troublesome, is easily lost lid or accidentally lid lid after use, actual use get up it is very inconvenient, so needing
Want improved test tube with cover that can just solve these problems.Meanwhile using liquid-transfering gun from test tube when draw solution, it usually needs will
Test tube, which is tilted a certain angle, to be come so that the syringe needle of liquid-transfering gun is easier to touch solution, but such operation will appear it is molten in test tube
The unrestrained phenomenon of liquid.
In order to solve the above problems, people are seeking always a kind of ideal technical solution.
Summary of the invention
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of test tube.
To achieve the goals above, technical solution used by the utility model is：A kind of test tube, it includes test tube sheet
Body, cylindrical spring test tube cap, back taper plug and elastic connecting strip；The upper end of the cylindrical spring test tube cap offers back taper
Hollow molded cavity, the lower end of the cylindrical spring test tube cap offer reservoir, and the outer diameter of the cylindrical spring test tube cap upper end is big
In the outer diameter of the test tube body, the outer diameter of the cylindrical spring test tube cap lower end is less than the internal diameter of the test tube body, described
The lower end of back taper plug is arranged in the back taper hollow molded cavity, and the cylindrical spring test tube cap passes through the back taper plug
It is sub to cooperate with test tube body sealing；
Elastic connecting strip is additionally provided on the cylindrical spring test tube cap, one end of the elastic connecting strip is connected with ring
Set, the ring set are set in the exterior side wall of the test tube body.
Based on above-mentioned, a plurality of elastic buffering strip is further fixedly arranged in the exterior side wall of the test tube body.
Based on above-mentioned, a plurality of elastic buffering strip is arranged in parallel.
The utility model has substantive features and progress compared with the prior art, and specifically, the utility model is provided
Test tube, test tube body and cylindrical spring test tube cap are linked together using the connecting band made of elastic material, in reality
Cylindrical spring test tube cap remains attached on test tube after testing, and avoids the problem that lid is lost or accidentally covered, very easy to use.
Further, test tube provided by the utility model on the nozzle of test tube body by being provided with back taper hollow molded cavity
Cylindrical spring test tube cap and back taper plug make cylindrical spring test tube cap tightly using back taper plug structure wide at the top and narrow at the bottom
It is inserted into the nozzle of test tube body, collision of the ordinary stoppers to test tube body is reduced when opening test tube body, and more hold
Easily open test tube body.Further, by the lower end of cylindrical spring test tube cap be arranged reservoir, using liquid-transfering gun from
In test tube when draw solution, a part of solution that can be trickled down using reservoir storage reduces the pollution probability of testing stand.

Chamber 7, the lower end of the cylindrical spring test tube cap 3 offer reservoir 8, and the outer diameter of cylindrical spring 3 upper end of test tube cap is greater than
The outer diameter of the test tube body 1, the outer diameter of cylindrical spring 3 lower end of test tube cap is less than the internal diameter of the test tube body 1, described
The lower end of back taper plug 4 is arranged in the back taper hollow molded cavity 7, and the cylindrical spring test tube cap 3 passes through the back taper
Shape plug 4 and the test tube body 1 sealing cooperate.
Elastic connecting strip 5 is additionally provided on the cylindrical spring test tube cap 3, one end of the elastic connecting strip 5 is connected with
Ring set 6, the ring set 6 are set in the exterior side wall of the test tube body 1.
Wherein, a plurality of elastic buffering strip 2 is further fixedly arranged in the exterior side wall of test tube body 1 described in the present embodiment.
The a plurality of elastic buffering strip 2 is arranged in parallel.The material of the cylindrical spring test tube cap 3 is rubber, the material of the test tube body 1
Matter is silica, and the material of the elastic buffering strip 2 is rubber, and the material of the back taper plug 4 is silica.
