Description
Technical field
The utility model relates to a kind of experiment equipment, particularly relates to a kind of Novel test-tube brush.
Background technology
Test-tube brush is a kind of instrument clearing up test tube, is mainly used in laboratory, is used for clearing up test tube when finishing test with test tube, is mainly made up of a simple iron wire and intensive thin filiform.
In an experiment, because the length of common test tube brush can not regulate, and the angle of bristle immobilizes, and for some stains, the spot especially bottom test tube, is difficult to clean out with common test-tube brush, and loses time very much.
Utility model content
the technical problems to be solved in the utility model is to provide a kind of Novel test-tube brush, can regulate the opening angle of overall length and cleaning bar, enable cleaning bar to bottom test tube and sidewall thoroughly clear up.
To achieve these goals, technical solution adopted in the utility model is: a kind of Novel test-tube brush, comprise columnar shell, outer casing inner wall offers stopper slot, cover top portion is provided with knob, be rotationally connected by snap fit and stopper slot bottom knob, leading screw is connected with bottom knob, leading screw outside has been threaded connection retracting cylinder, the bottom-hinged of retracting cylinder sidewall is provided with ratchet, retracting cylinder is provided with the tooth bar coordinated with ratchet, ratchet edge is provided with cleaning bar, at least three, described ratchet, ratchet circumferentially array centered by the axis of retracting cylinder.
As a kind of optimal technical scheme of the present utility model, described ratchet is arranged along the radial direction of described retracting cylinder, and described tooth bar is just to the center of described ratchet wheel face, and described cleaning bar is arranged on the side of described ratchet wheel face.
Adopt the beneficial effect that produces of technique scheme to be: the utility model can regulate the opening angle of overall length and cleaning bar, is applicable to the test tube of clean different model, enable cleaning bar to bottom test tube and sidewall thoroughly clear up.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is sectional view of the present utility model.
Fig. 2 is the partial enlarged drawing of part A in Fig. 1.
In figure: 1, shell 2, knob 3, leading screw 4, retracting cylinder 5, ratchet 6, cleaning bar 7, snap fit 8, tooth bar.
Detailed description of the invention
Referring to accompanying drawing, the structure of the utility model detailed description of the invention comprises columnar shell 1, shell 1 inwall offers stopper slot, shell 1 top is provided with knob 2, be rotationally connected by snap fit 7 and stopper slot bottom knob 2, leading screw 3 is connected with bottom knob 2, leading screw 3 outside has been threaded connection retracting cylinder 4, the bottom-hinged of retracting cylinder 4 sidewall is provided with ratchet 5, retracting cylinder 4 is provided with the tooth bar 8 coordinated with ratchet 5, ratchet 5 edge is provided with cleaning bar 6, 5 at least three, described ratchet, ratchet circumferentially array centered by the axis of 5 retracting cylinders 4.
Described ratchet 5 is arranged along the radial direction of described retracting cylinder 4, and described tooth bar 8 is just to the center of described ratchet 5 wheel face, and described cleaning bar 6 is arranged on the side of described ratchet 5 wheel face.Tooth bar 8 and cleaning bar 6 shift to install on the wheel face of ratchet 5, are stumbled when preventing cleaning bar 6 from rotating with ratchet 5 by tooth bar 8.
Operation principle of the present utility model is: the utility model can regulate the opening angle of overall length and cleaning bar 6, is applicable to the test tube of clean different model, make cleaning bar 6 can to bottom test tube and sidewall thoroughly clear up.
Length adjustment is controlled by knob 2, and specifically, knob 2 drives leading screw 3 to rotate, and leading screw 3 makes retracting cylinder 4 realize lifting by screw thread, and its entire length can be adjusted.Wherein snap fit 7 and stopper slot can prevent knob 2 from coming off from shell 1.
The angular adjustment of cleaning bar 6, ratchet 5 only uniaxially rotates, and specifically, the bottom wheel face of ratchet 5 can only outwards rotate, and can use after being adjusted to proper angle, even if test tube wall extruding cleaning bar 6, ratchet 5 also can not reversely rotate; Illustrate, when clearing up bar 6 angle and needing to turn down, need ratchet 5 to rotate continuously, make cleaning bar 6 continue to rotate after the upper wheel face of ratchet 5 turns over the sidewall of retracting cylinder 4 from outside to inside, now can regulate from zero degree.
Foregoing description only proposes, not as the single restrictive condition to its technical scheme itself as the enforceable technical scheme of the utility model.
