Description
Technical field
The utility model is related to a kind of novel volumetric flask fixing devices, belong to laboratory technical field of auxiliary facilities.
Background technology
In laboratory research and experiment, it is often necessary to use volumetric flask constant volume, the solution after constant volume to be removed with pipette,
The volumetric soiutions of removal are titrated with buret later, since pipette is long, bad grasp, liquid relief in operating process
Pipe lower end is easy to fall on volumetric flask band, it is more inconvenient that since volumetric flask bottleneck bore is smaller, operator one holds rubber pipette bulb
One hand-held volumetric flask can not pipette up a small amount of solution of volumetric flask bottom, in order to avoid the waste of a small amount of liquid of bottom of bottle,
Other people are needed to help to coordinate volumetric flask is tilted a certain angle carry out liquid relief when use, this brings inconvenience to operating process.
Invention content
The utility model aim is to provide a kind of novel volumetric flask fixing device, it can effectively solve the problem that in background technology
The problems of.
The utility model provides a kind of novel volumetric flask fixing device, including pedestal, the side of the pedestal are equipped with
Vertical fixed link, the vertical fixed link move horizontally bar equipped with one, and moving horizontally bar can exist along vertical fixed link
It is moved up and down on vertical direction, the bar free end that moves horizontally is equipped with volumetric flask bottleneck fixed part, the volumetric flask bottle
Mouthful fixed part and moving horizontally is connected with knob between bar, which can be with thread spindle two for 360 ° of fulcrum
Rotation, can be with the angle of inclination of pondage bottle by rotation, while the free end of the vertical swingle is equipped with volumetric flask
Bottleneck geometrical clamp can play the role of fixed capacity bottle.
Preferably, the size of the geometrical clamp for moving horizontally bar free end, geometrical clamp can be according to volumetric flask bottleneck
Caliber size is adjusted.
Preferably, the height of the vertical fixed link is not less than 60cm.
The utility model provides a kind of novel volumetric flask fixing device, easy to use, simple in structure, can guarantee appearance
Measuring bottle a small amount of solution in volumetric flask bottom in pipetting processes does not waste, and volumetric flask is not easy to topple in operating process.

Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1 Fig. 2 Fig. 3, a fixing frame for volumetric flask, including pedestal 1, vertical fixed link 2, screw threads for fastening knob one
3, orthogonal bars fixator 4, screw threads for fastening knob 25 moves horizontally bar 6, rubber fastening gasket 1, rubber fastening gasket 8, riveting
Nail 9, thread spindle 1, wheel flange 1, wheel flange 2 12, screw threads for fastening knob 3 13, thread spindle 2 14, screw threads for fastening knob
4 15.Wherein, it moves horizontally tight with orthogonal bars fixator 4, screw threads for fastening knob 1 and screw thread between bar 6 and vertical fixed link 2
Gu knob 25 is attached fixation, moving horizontally bar 6 can move up and down along vertical fixed link 2.Wheel flange 1 and clamping
It encloses 2 12 and is fixed together by rivet 9, thread spindle 1, screw threads for fastening knob 3 13 and form volumetric flask bottleneck geometrical clamp, this is solid
Clamp is fastened on water by rubber fastening gasket 1, rubber fastening gasket 28, thread spindle 2 14, screw threads for fastening knob 4 15
Translate in lever 6, and can by adjust 4 15 pairs of geometrical clamps of screw threads for fastening knob and move horizontally angle between bar 6 into
Row is adjusted, convenient to be pipetted to a small amount of solution of volumetric flask bottom of bottle to make volumetric flask tilt certain angle, reduces solution wave
Take, and volumetric flask bottleneck is clamped in geometrical clamp, and fixed function is played to volumetric flask.
The bottleneck geometrical clamp of volumetric flask can be according to the bottle caliber size of volumetric flask by tuning screw threads for fastening knob 3 13
It is adjusted.
The height of vertical fixed link 2 is not less than 60cm, and laboratory technician is facilitated to operate.
The utility model provides a kind of fixing device of volumetric flask, simple in structure, easy to use, with pipette pair
During a small amount of solution of volumetric flask bottom of bottle carries out liquid relief, be avoided that is inconvenient to pipette because bottom of bottle solution is very little, to reduce
Waste, while fixed capacity bottle can be played the role of, it is used for chemical laboratory.
