Description
technical field:
The utility model relates to a kind of flask brush.
background technology:
Round-bottomed flask is reaction vessel conventional in chemical test, mostly normally usedly is single port or there-necked flask.On the bottom that after some chemical reactions complete, the residue of generation sticks to flask or wall, especially in organic test, the material that some of generation have a high viscosity is difficult to be washed away by liquid the method removing of dissolving.Conventional washing methods is that the good solvent adding this kind of reaction residue soaks or ultrasonic method.All there is certain defect in these two kinds of methods, the method for solvent needs certain immersion reaction time and repeatedly flush clean, ultrasonicly requires the expenditure of energy and easily produce noise.Brush cleaning is used to be a kind of simple effective method.
The conventional test-tube brush in current laboratory is mostly brush core with iron wire, and iron wire adheres to bristle.This straight brush can be very convenient, effectively cleans up straight barrel type glass apparatus, such as test tube, graduated cylinder etc.But for round-bottomed flask, because flask exists certain radian, straight test-tube brush is bent certain angle by experimenter usually, but inconvenient and easily damage is caused to iron wire brush core.Because the select permeability of angle often can not clean up flask effectively.Meanwhile, irony brush core is easy to the rust corrosion being subject to the chemicals such as acid, produces again pollute when cleaning flask.Cannot change after bristle wear shortens in addition, reduce the life cycle of brush.
Therefore, necessary the deficiency solving prior art is improved to prior art.
summary of the invention:
The utility model provides a kind of flask brush to solve above-mentioned prior art Problems existing.
The technical scheme that the utility model adopts has:
A kind of flask brush, comprise brush holder, angular adjustment bar and brush, the upper end of described angular adjustment bar and the lower end of brush holder are flexibly connected, described angular adjustment bar upper end is provided with U-shaped bayonet socket, U-shaped bayonet socket sidewall is provided with housing screw, brush holder lower end is provided with column connector, described column connector is plugged in U-shaped bayonet socket, column connector is tight against on U-shaped bayonet socket madial wall by housing screw, described angular adjustment bar lower end sidewall is provided with external screw thread, brush is fixedly connected with sleeve pipe, internal surface of sleeve pipe is provided with the internal thread suitable with external screw thread on described angular adjustment bar, brush spiral is connected to angular adjustment bar lower end.
Further design of the present utility model is:
Described brush holder upper end is provided with and buckles.
Described brush adopts spherical brush.
The surface of described brush holder, angular adjustment bar and brush all scribbles acid-fast alkali-proof material.
the utility model has following beneficial effect:
(1) the utility model can regulate the angle between brush holder and brush easily, makes brush touch flask walls better.
(2) the spherical design of brush increases the contact area with flask walls, fast and effeciently cleans up flask.
(3) brush spiral is connected on angular adjustment bar, is convenient to more changing brush head, saves cost.
accompanying drawing illustrates:
Fig. 1 is the utility model flask brush structure chart.
Fig. 2 is angular adjustment bar structure chart in the utility model flask brush.
Fig. 3 is handle structure figure in the utility model flask brush.
Wherein
1, brush holder; 2, angular adjustment bar; 3, brush; 11, column connector; 12, buckle; 21, U-shaped bayonet socket; 22, housing screw; 31, sleeve pipe.
detailed description of the invention:
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to Fig. 1 to Fig. 3, a kind of flask brush of the utility model, there is brush holder 1, angular adjustment bar 2 and brush 3, brush holder 1 is movably connected in the upper end of angular adjustment bar 2, brush 3 is movably connected in the lower end of angular adjustment bar 2, U-shaped bayonet socket 21 is provided with in the upper end of angular adjustment bar 2, the sidewall of U-shaped bayonet socket 21 is provided with housing screw 22, the utility model is in order to connect brush holder 1 and angular adjustment bar 2 better, column connector 11 is provided with in the lower end of brush holder 1, brush holder 1 is plugged in U-shaped bayonet socket 21 by column connector 11, after column connector 11 grafting is good, tighten housing screw 22, by housing screw 22, column connector 11 is tight against on U-shaped bayonet socket 21 madial wall, then brush holder 1 is made to be plugged in angular adjustment bar 2, when needing to regulate the angle between brush holder 1 and angular adjustment bar 2, unscrew housing screw 22, adjusting angle adjusting rod 2 and brush holder 1 are to required angle, then housing screw 22 is tightened.
The utility model is in order to the more changing brush head 3 when not changing brush holder 1, angular adjustment bar 2 lower end sidewall is provided with external screw thread, fixed connecting sleeve 31 on brush 3, sleeve pipe 31 inwall is provided with the internal thread suitable with angular adjustment bar 2 lower end external screw thread, and brush 3 is connected to the lower end of angular adjustment bar 2 by sleeve pipe 31 spiral.The utility model brush 3 adopts spherical brush, and spherical brush can increase the contact area of brush and flask walls.
The upper end of brush holder 1 is provided with and buckles 12, being convenient to the utility model flask brush not using the moment hangs over fixed position, brush holder 1 in the utility model, angular adjustment bar 2 and brush 3 surface all scribble the composite ceramic material of acid-fast alkali-proof, thus increase the service life of flask brush.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
