Abstract
The utility model discloses a kind of test tube, comprise body, the mouth of pipe and bottom, circular protrusion and test tube handle is provided with outside body, bottom outer wall is cylindrical, bottom interior wall is back taper, and this test tube also comprises test tube cap, and described test tube cap comprises the connecting ring, flexible connecting member, top cover and the inner cap that are fixed on body, described inner cap is positioned at top cover centre and matches with the mouth of pipe, and described top cover is fixedly connected with connecting ring by flexible connecting member.The advantage of this test tube is, can make full use of the rack for test tube of various model; Test tube bottom outer wall is cylindrical, and bottom interior wall is that the structure of back taper effectively prevents from crashing bottom test tube, makes a small amount of product accumulation be convenient to draw at the bottom of pipe.
Description
Technical field
The utility model relates to and belongs to experiment equipment field, especially a kind of test tube.
Background technology
Test tube, as the instrument that chemical laboratory is conventional, both can as the container of little quantitative response, also can be collect efflux at column chromatography, but current test tube is all that sidewall is cylindrical, bottom arc-shaped structure, need just can place by positioners such as rack for test tubes, and bottom easily breaks up, reactant or product is caused to spread out.
Test tube hole on current same rack for test tube is all of a size, for minor diameter test tube can not be stable be placed on and have in wide-aperture test tube hole, if when small-bore rack for test tube shortage, the rack for test tube of other models effectively can not be used.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of test tube, can be suitable for large aperture rack for test tube, can also prevent bottom test tube broken.
The technical solution adopted in the utility model is: a kind of test tube, comprises body, the mouth of pipe and bottom, is provided with circular protrusion outside described body, and described bottom outer wall is cylindrical, and bottom interior wall is back taper.
This test tube also comprises test tube cap, and described test tube cap comprises the connecting ring, flexible connecting member, top cover and the inner cap that are fixed on body, and described inner cap is positioned at top cover centre and matches with the mouth of pipe, and described top cover is fixedly connected with connecting ring by flexible connecting member.
Described circular protrusion has two, and is arranged above and below along body, and the diameter of upside circular protrusion is greater than downside circular protrusion.
Described body is provided with test tube handle.
The beneficial effects of the utility model: be provided with circular protrusion outside body, can be placed on test tube in wide-aperture rack for test tube, make full use of the rack for test tube of various model; Test tube bottom outer wall is cylindrical, and bottom interior wall is that back taper both can ensure not contact desktop bottom test tube, effectively prevents from crashing bottom test tube, and a small amount of product accumulation can also be made to be convenient to draw at the bottom of pipe; Body is provided with test tube handle and facilitates test tube to take.
Accompanying drawing explanation
Fig. 1 is three-dimensional structure diagram of the present utility model;
Fig. 2 is sectional view of the present utility model;
In figure, 1, the mouth of pipe, 2, body, 3, bottom, 4, upside circular protrusion, 5, downside circular protrusion, 6, bottom interior wall, 7, bottom outer wall, 8, test tube handle, 9, connecting ring, 10, flexible connecting member, 11, top cover, 12 inner caps.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of test tube, comprise body 2, the mouth of pipe 1 and bottom 3, two circular protrusions be arranged above and below along body 2 are provided with: the diameter of upside circular protrusion 4 is greater than downside circular protrusion 5 outside body 2, test tube can be placed in wide-aperture rack for test tube, by circular protrusion, test tube is fixed, make full use of the rack for test tube of various model;
Bottom outer wall 7 is cylindrical, and bottom interior wall 6, in back taper, ensure that and do not contact desktop bottom test tube, effectively prevent from crashing bottom test tube, and a small amount of product accumulation can also be made to be convenient to draw at the bottom of pipe.
This test tube also comprises test tube cap, and test tube cap comprises the connecting ring 9, flexible connecting member 10, the top cover 11 that are fixed on body 2 and to be positioned in the middle of top cover 11 and the inner cap 12 matched with the mouth of pipe 1, and top cover 11 is fixedly connected with connecting ring 9 by flexible connecting member 10.Test tube cap is clogged the mouth of pipe and form a closed container, the material of the inside can not scatter and prevent cross pollution, and after opening test tube cap, test tube cap, owing to being fixed on body by connecting ring, can not be lost.
Body 2 is provided with test tube handle 8, facilitates test tube to take.
