Abstract
The utility model discloses a test tube. The test tube is a cylindrical tubular container with a closed end; at least one bulge is arranged on the outer wall of the test tube; when the test tube is placed on an oblique table surface, the bulges on the outer wall of the test tube can prevent the test tube from rolling, so that the loss caused by the falling of the test tube is prevented; moreover, the test tube can be inserted into a test tube rack, and the bulges can prevent the test tube from being in contact with the bottom layer of the test tube rack, so that the test tube cannot collide with the bottom layer of the test tube rack, and is free from breaking.
Description
Technical field
The utility model relates to a kind of test tube of depositing liquid.
Background technology
Test tube is a kind of utensil commonly used in biology and chemical experiment, and at present, the test tube of use for laboratory is the cylindrical tubular container of the end closure made of glass mostly.When this class teat glass lies in slightly on the desktop that tilts, will roll because being subject to Action of Gravity Field,, in case tumble to ground, will fragmentation cause damage and even cause danger.
Be useful on now the rack for test tube of holding test tubes, major part is sandwich construction, and the superiors are provided with the circular hole that can insert test tube.This type of rack for test tube mostly is metallic article, and quality is harder, when we insert test tube, in case hand is not caught, it is freely fallen, and very likely because of the shock of test tube and rack for test tube bottom, makes tube breaking, causes the in vitro loss of sample.
Summary of the invention
The purpose of this utility model is to provide a kind of test tube, and this test tube can not roll on the desktop that slightly tilts, and after test tube was inserted rack for test tube, test tube can not contact with the rack for test tube bottom, the tube breaking of having avoided collision to cause.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of test tube, this test tube are the cylindrical tubular container of an end closure, and described test tube outer wall is provided with at least one projection.
In technique scheme, described test tube outer wall is provided with two projections, and described two projections are positioned on the different vertical directions of test tube outer wall.
In technique scheme, described two projections equate to the distance of test tube mouth.
In technique scheme, the distance between described two projections is 0.25～0.6 with the ratio of described test tube external diameter.
The utility model compared with prior art, has following beneficial effect:
Test tube outer wall described in the utility model is provided with projection, when this test tube placing flat is occurred to roll on the desktop that slightly tilts,, because the obstruction of projection can make test tube stop rolling, prevents that it from dropping from desktop.Simultaneously, when this test tube is inserted rack for test tube,, because the inhibition of projection makes test tube can't be inserted into the rack for test tube bottom, avoided the collision of test tube and rack for test tube bottom, eliminated and collided the possibility that causes tube breaking.
Description of drawings
Fig. 1 is the side view that is provided with the test tube of a projection.
Fig. 2 is the top view that is provided with the test tube of a projection.
Fig. 3 is the side view that is provided with the test tube of two projections.
Fig. 4 is the top view that is provided with the test tube of two projections.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
See Fig. 1～Fig. 2, a kind of test tube 1, this test tube 1 is the cylindrical tubular container of an end closure, test tube 1 outer wall is provided with a projection 2, when test tube 1 being lain on the desktop that slightly tilts, when test tube 1 generation was rolled, the inhibition due to protruding 2 made test tube 1 stop rolling, and prevented that it from dropping fragmentation occurs from desktop.Simultaneously, when this test tube 1 was inserted rack for test tube, the inhibition due to protruding 2 made test tube 1 can't be inserted into the rack for test tube bottom, had avoided the collision of test tube 1 with the rack for test tube bottom, had eliminated the possibility that collision causes test tube 1 to break.
See Fig. 2～Fig. 3, a kind of test tube 1, this test tube 1 is the cylindrical tubular container of an end closure, test tube 1 outer wall is provided with two projections 2,2 ', two projections 2,2 ' is positioned on the different vertical directions of test tube 1 outer wall, when test tube 1 being lain on the desktop that slightly tilts, when test tube 1 occurs to roll, due to projection 2,2 ' inhibition makes test tube 1 stop rolling, and prevents that it from dropping fragmentation occurs from desktop, than the test tube that is provided with a projection 2, be provided with the rolling amplitude that the test tube of two projections 2,2 ' can further dwindle test tube 1.Simultaneously, when this test tube 1 was inserted rack for test tube, the inhibition due to protruding 2,2 ' made test tube 1 can't be inserted into the rack for test tube bottom, had avoided the collision of test tube 1 with the rack for test tube bottom, had eliminated the possibility that collision causes test tube 1 to break.Two projections 2,2 ' are equal to the distance of test tube mouth, and when test tube 1 was inserted rack for test tube, projection 2,2 ' can be blocked test tube simultaneously, makes the test tube stress balance.Further, two projections 2, the distance between 2 ' is 0.25～0.6 with the ratio of test tube 1 external diameter, in this scope, can erect test tube when two projections 2,2 ' all contact with desktop, makes test tube there is no the amplitude of rolling.
