Abstract
The utility model relates to a liquid transfer pipe and belongs to the technical field of chemical equipment. The liquid transfer pipe comprises a main pipe with scales, a cylindrical knob, a rope, a round ball, a side pipe and a truncated cone shaped plug, wherein the side pipe is arranged at one side of the upper part of the main pipe; the truncated cone shaped plug is arranged in the side pipe; the upper end in the main pipe is provided with the round ball; the cylindrical knob which penetrates through the main pipe is arranged above the round ball; and one end of the rope is fixed on the cylindrical knob, and the other end of the rope is connected with the round ball. The liquid transfer pipe is convenient to operate, accurate to control and simple in structure.
Description
Technical field
The utility model relates to
OnePlant pipette, belong to chemical equipment technical field.
Background technology
Pipette use procedure in existing chemical test is roughly: left hand takes rubber pipette bulb from the pipette upper orifice, solution to be sucted, when liquid level rises to the scale that needs when above, block the mouth of pipe with right hand forefinger rapidly, unclamp a little the right hand forefinger during tapping liquid level is slowly descended.This gets in the liquid process, moves away to when blocking with right hand forefinger from rubber pipette bulb, if action can not cause rapidly getting the liquid measure deficiency because of liquid too fast the causing that descend; When tapping, unclamp finger or slightly rotate in the pipette process all more difficult control tapping amounts; Very difficult grasp picks and places liquid accurately, simultaneously operator's finger manipulation is had relatively high expectations.
Summary of the invention
The purpose of this utility model be to provide a kind of easy to operate, control accurately and pipette simple in structure.
The technical solution of the utility model is: a kind of pipette comprises supervisor 1, cylindrical knob 2, rope 3, ball 4, side pipe 5, circular platform type stopper 6 with scale.Be responsible for 1 top one side and be shaped with side pipe 5, circular platform type stopper 6 is housed in side pipe 5, supervisor's 1 inner upper end is equipped with ball 4, and the cylindrical knob 2 that passes supervisor 1 is equipped with in ball 4 tops, and rope 3 one ends are fixed on cylindrical knob 2, the other end is connected with ball 4.
Described side pipe 5 is tubular structure wide at the top and narrow at the bottom, and it is narrow end with being responsible for 1 junction.
Described supervisor 1 top is tubular structure wide at the top and narrow at the bottom.
Described cylindrical knob 2 round bar parts and supervisor's 1 outer wall vertical.
During use, the rubber pipette bulb of first holding with a firm grip is discharged air in ball, the rubber pipette bulb sharp-crested is inserted and is right after in side pipe 5, attention can not be leaked gas, the finger that comes up, and circular platform type stopper 6 can be by outside sucking-off a bit, and make circular platform type stopper 6 and side pipe 5 produce the space, at this moment liquid is inhaled in supervisor 1, when liquid level rises to the scale that needs when above, removes rubber pipette bulb, circular platform type stopper 6 can be because of Action of Gravity Field again with side pipe 5 jam-packs, thereby liquid can not be flowed out; During regulating liquid surface, the rotary cylinder knob 2 slightly, and cord 3 can produce fine gap between ball 4 and supervisor's 1 inwall because on cylindrical bar, ball 4 being pulled upwardly slightly, and liquid is slowly flowed out, but the fine adjustment liquid level; During complete tapping, be rotated further cylindrical knob 2, increase gap accelerating liquid decrease speed; After tapping is completed, decontrol rotary cylinder knob 2, ball 4 is because gravity falls jam-pack supervisor 1 again.
The beneficial effects of the utility model are: easy to operate, control accurately and simple in structure.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure, each label is: 1: supervisor, 2: cylindrical knob, 3: rope, 4: ball, 5: side pipe, 6: the circular platform type stopper.
