Description
Technical field
The utility model relates to a kind of test-tube brush, particularly a kind of deployable and collapsible safety test tube brush.
Background technology
As timely in needs such as beaker, conical flask, graduated cylinder, volumetric flask, the wide-mouth bottles cleaning of glass container that laboratory is conventional.Because large-scale cleaning machine involves great expense, laboratory is often used test-tube brush to carry out manual cleaning to reagent bottle.The general similar cylindrical shape of common test-tube brush, also having some is test-tube brushes of the special shape made for special container, these test-tube brushes mainly have following deficiency: 1, because the bore of glass container is generally less, common test-tube brush can not be stretched or cannot be cleaned whole wall of cups; 2, the end of test-tube brush uses usually to expose tip of a specified duration, not only cannot cleaning container bottom but also destroy container bottom and cause container broken, and use dangerous and need often to change; 3,, because the reagent bottle that need to clean every day in laboratory is more, use common test-tube brush manual cleaning to waste time and energy.
To sum up, existing test-tube brush not only consumes wealth consumption power, also likely dangerous or affect owing to not cleaning up the failure that experiment accuracy even can cause experiment.Therefore it is necessary, studying a kind of test-tube brush lower-cost and can safe and effective cleaning reagent bottle.
Summary of the invention
For the defect existing in above-mentioned prior art or deficiency, the purpose of this utility model is, a kind of deployable and collapsible safety test tube brush is provided.
To achieve these goals, the utility model adopts following technical scheme:
A kind of deployable and collapsible safety test tube brush, comprise pull bar, setscrew nut, sleeve, the first brush holder, the second brush holder, first connecting rod and second connecting rod, wherein, described sleeve is hollow column, pull bar passes and can in sleeve, move around from sleeve, setscrew nut is enclosed within on pull bar, and the first half outer wall of pull bar is provided with the external screw thread matching with setscrew nut; The upper end of the first brush holder and the second brush holder is hinged on sleeve lower end, on the first brush holder, is hinged with first connecting rod, and position corresponding with the first brush holder on the second brush holder is hinged with second connecting rod; The lower end of first connecting rod and second connecting rod is all hinged with the lower end of pull bar; The first brush holder and the second brush holder outside are all coated with bristle.
Further, in the lower end of described the first brush holder and the second brush holder, by a hemisphere, wrap up, hemisphere outside is coated with bristle.
Further, in the upper end of described pull bar, be provided with draw ring.
The beneficial effects of the utility model are:
(1) added pull bar, and common brush holder has been divided into two, for different form in different reagent bottles and same reagent bottle, by adjusting two angles between brush holder, made to clean flexible, can a brush multiplex.
(2) by apply mechanically hemisphere anti-damage instrument in brush holder bottom, solved use safety problem.
(3) than large-scale cleaning machine, it is little that the utility model takes up an area, and saved manpower, material resources and financial resources, realized the object of rapid cleaning, safety low expense.Can be widely used in the laboratory of school, the medium and small laboratory of enterprise or research institute etc.
(4) brush holder material has adopted and has had certain flexible vulcanie, can be according to the inwall generation deformation of container to be cleaned, thus can clean the container of spherical or arc inner wall, as balloon flask.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is for the state of conical flask.
Fig. 3 is that the utility model is for the state of aryballos.
Below in conjunction with the drawings and specific embodiments, the utility model is further explained.
The specific embodiment
As shown in Figure 1, deployable and collapsible safety test tube brush of the present utility model, comprise pull bar 2, setscrew nut 3, sleeve 4, the first brush holder 5, the second brush holder 6, first connecting rod 7 and second connecting rod 8, wherein, described sleeve 4 is hollow column, pull bar 2 passes and can in sleeve 4, move around from sleeve 4, and setscrew nut 3 is enclosed within on pull bar 2, and the first half outer wall of pull bar 2 is provided with the external screw thread matching with setscrew nut 3; The upper end of the first brush holder 5 and the second brush holder 6 is hinged on sleeve 4 lower ends, is hinged with position corresponding with the first brush holder 5 on first connecting rod 7, the second brush holders 6 and is hinged with second connecting rod 8 on the first brush holder 5; The lower end of first connecting rod 7 and second connecting rod 8 is all hinged with the lower end of pull bar 2; The first brush holder 5 and the second brush holder 6 outsides are all coated with bristle.
Wrap up by a hemisphere 9 lower end at the first brush holder 5 and the second brush holder 6; The material of this hemisphere 9 is rubber or other elastomeric materials.Hemisphere 9 is for preventing that the top of hairbrush cannot cleaning container bottom and destruction container bottom from bristle exposes.
In the upper end of pull bar 2, be provided with draw ring 1, draw ring 1 when adjusting pull bar 2 with respect to the position of sleeve 4 for hand-held.
The material of the first brush holder 5 and the second brush holder 6 is vulcanie, and the material of sleeve 4, connecting rod 2, setscrew nut 3 is engineering plastics.Adopt engineering plastics both to guarantee whole intensity, avoid again the corrosion of metal material and the danger of damage glass apparatus.
Principle of the present utility model is as follows:
By pull bar 2, the relative position at sleeve 4 determines angle between the first brush holder 5 and the second brush holder 6; When needs clean reagent bottle, angle between the first brush holder 5 and the second brush holder 6 in minimum state to make it enter reagent bottleneck, according to the position of the size in reagent bottle and needs brush, adjust the angle between the first brush holder 5 and the second brush holder 6.Concrete adjustment way is: when the angle between needs the first brush holder 5 and the second brush holder 6 increases, by draw ring 1, pull pull bar 2, pull bar 2 upwards drives first connecting rod 7 and second connecting rod 8 to move obliquely, the angle of realizing between the first brush holder 5 and the second brush holder 6 opens, until stop drag draw ring after reaching the reagent bottle inner space that needs to clean, and setscrew nut 3 is tightened downwards.Under this state, setscrew nut 3 is stuck in the upper end of sleeve 4, guarantees that pull bar 2 can not move down with respect to sleeve 4, thereby prevents that in use the first brush holder 5 and the second brush holder 6 inwardly shrink, and affects cleaning performance; When the utility model is used to complete, while cleaning the identical container of upper and lower bore or while just having entered vessel port, capable of regulating setscrew nut 3, makes pull bar 2 move down with respect to sleeve 2, makes the first brush holder 5 and the second brush holder 6 in merger trend.
