Description
Technical field
The utility model belongs to small-size laboratory articles field, is related to a kind of volumetric flask plug sleeve, more particularly, to one kind
It can be to avoid the volumetric flask plug sleeve of bottle stopper and volumetric flask pairing mistake, pollution, damage.
Background technique
Experiment of Analytical Chemistry room need to use volumetric flask to carry out constant volume when configuring actual concentrations solution, and volumetric flask is a kind of essence
True instrument is composed of two elements of body and bottle stopper, needed before using volumetric flask detection bottle stopper it is whether tight, it is water-tight then
Indicate volumetric flask good airproof performance.
A kind of volumetric flask volumetric flask of model when producing early stage can only match the bottle stopper of contract-type number.Before preparing solution,
First to understand the bottle stopper with volumetric flask same model.
Volumetric flask generates the influence that bottle stopper and volumetric flask can not match after experiment is completed and executes cleaning procedure, by
Caused by the volumetric flask bottle stopper of co-content different model only has narrow difference, the two can be used together but can not be closely sealed, and causes
Leakage is fallen broken.
Capacity bottle stopper often designs for cone cell, and being put on table after opening can not fix and roll is contaminated it everywhere, dirty
The solution that the part of dye will affect configuration causes test error.
User can be lain in bottle stopper at capacity bottle neck with continuous rope, nylon rope, rubber band etc. before using volumetric flask, material
The selection of matter and the method for tying up have resulted in the influence of solvent contamination and volumetric flask damage in volumetric flask.
After volumetric flask and bottle stopper are tied, it will not be dismantled when cleaning volumetric flask, therefore bottle stopper is caused to collide appearance
Measuring bottle makes it generate rupture and damages.
When being binding material with rubber band, is occurring rubber aging phenomenon after use for several times, bottle stopper is made to be easy pine
It is de-；This material is not acidproof, and the appearance of rubber residue is had at capacity bottle neck, and cleaning is difficult.
Therefore, one kind can unload cleaning easily, will link between bottle stopper and volumetric flask, can prevent bottle stopper from colliding capacity again
The design of bottle can reduce the pollution and rupture of capacity bottle neck, can help to solve the problem above-mentioned.
Summary of the invention
To realize above-mentioned function, the utility model relates to a kind of volumetric flask plug sleeve, it is characterised in that: including fixinig plate
(1) and the part of plug sleeve (2) two.
Wherein, tool umbrella in fixinig plate (1) one end is raised (3), and the other end is coupled with plug sleeve (2), in the middle part of fixinig plate (1) uniformly
It is distributed the groove (5) of 3 with raised (3) equal-specification of umbrella, is divided between groove (5) and groove (5), groove (5) and umbrella raised (3)
Not Ju You 4 towards consistent U-shaped body (4).Fixinig plate (1) one end has umbrella raised (3) can be with uniform point in the middle part of fixinig plate (1)
Cloth 3 and the groove (5) of raised (3) equal-specification of umbrella combine, that is, form a kind of circular ring structure, this lantern ring can be by solid
The size of groove (5) the adjustment lantern ring of stator (1), meets the volumetric flask of different size.U-shaped body (4) design on fixinig plate (1)
A kind of volumetric flask plug sleeve can be made close to body, the friction generated when reducing overturning volumetric flask.Plug sleeve (2) by elastic surface A (6) and
Elastic surface B (7) is constituted, and elastic surface A (6) and elastic surface B (7) are rounded square and are connected by elastic piece (9), placed in the middle to have
Flexible netted face (8).Wherein, it is raised (3) to all have umbrella for four angles of elastic surface A (6), and elastic surface B (7) is in correspondence
Position all has the groove (5) of equal-specification.The umbrella of elastic surface A (6) raised (3) can be with elastic surface B (7) in corresponding position isotactic
The groove (5) of lattice is engaged combination, can be placed in volumetric flask bottle stopper of various shapes, the design of covering property is it is possible to prevente effectively from bottle inlet
Plug causes to damage with volumetric flask collision.The netted face (8) of plug sleeve (2) can be easy draining in cleaning and not cause water stain residual；Button
Pressure design is easy to disassemble, is convenient for lab assistant one-handed performance.
The utility model is the individual being fabricated to using die press technology for forming, and with polypropylene, polyurethane, polytetrafluoroethyl-ne
One or more of alkene material is made, and has the function of anti-strong acid caustic corrosion and organic solvent-resistant.
The beneficial effects of the utility model are as follows:
The utility model innovates the mode of connection of volumetric flask and bottle stopper according to laboratory routine operation demand, if
Count into a kind of volumetric flask plug sleeve.Compared to more other kinds of capacity bottle stopper mode of connection, the connection of the invention is designed, more effectively
Prevent connection bottle stopper collide volumetric flask, make its fragmentation；And collar design can be removed easily, be readily cleaned bottleneck, plug
Set can also shelve bottle stopper, save the time of bottle stopper and volumetric flask pairing, reach reduction pollution probability.
