Description
Technical field
The present invention relates to laboratory fluids dispensing apparatus technical field, especially a kind of use for laboratory solution quantitative separating
Device.
Background technology
Liquid dispenser is usually a kind of little container of the big discharging opening of charging aperture, dedicated for thinner for liquid injection entrance
In little container, guide functions are played.Laboratory is currently used for the instrument of solution subpackage beaker, graduated cylinder and reagent bottle etc., with burning
Cup, graduated cylinder or reagent bottle etc. are dispensed into solution in the vessel such as small beaker, little graduated cylinder, burette, conical flask, volumetric flask.Due to
Existing beaker, graduated cylinder and reagent bottle etc. are all open ports, for expose in atmosphere unstable volatile, oxidizable,
The subpackage of the reagent such as hygroscopic, inflammable, perishable, explosive, hypertoxic, carcinogenic, pathogenic and preparation are just very inapplicable, and existing instrument
The amount of being difficult to control to when can not observe exact volume, the subpackage for flowing out solution while subpackage.
Content of the invention
The present invention provides a kind of use for laboratory solution quantitative dividing device, and it can solve existing use for laboratory in subpackage liquid
Dispenser can not control the problem of fluid flow.
In order to solve above-mentioned technical problem, the technical solution adopted in the present invention is：Charging aperture and bottom are provided with including top
Portion is provided with the container body of discharging opening, and the container body is column, and the container is externally provided with fixed handle, the fixed handle and institute
State, the bottom of the flexible handle is provided with to be stretched into the container body bottom and seal the discharging
The switch inserted sheet of mouth, is crimped with shell fragment between the flexible handle and the top of the fixed handle；The charging of the container body
Mouth is provided with lid, and the lid is provided with aperture, is connected to water dropper under the discharging opening.
In above-mentioned technical proposal, more specifically scheme can also be：On the flexible handle top and the fixed handle
Portion is fixedly installed, and is provided with compression spring between the flexible handle hypomere and the fixed handle hypomere；The container body bottom
Side is provided with the socket for the switch inserted sheet turnover, and the water dropper is spirally connected with the discharging opening.
Further：The container body is made up of epimere, stage casing and hypomere, and three sections of diameter ratio is 4:2:1, the container
Body is made up of clear glass, and container body is marked with volume markings.
Further：The container body is erected in a support, and the support is made up of upper and lower two rings, and upper ring internal diameter is less than
Lower ring internal diameter, the upper ring are connected by three symmetrically arranged support feets with the lower ring.
Due to adopting above-mentioned technical proposal, the present invention compared with prior art, to have the advantages that：
1st, due to being provided with flexible handle on the inside of handle and container body between, the bottom of the flexible handle is provided with stretches into container body bottom
And seal the switch inserted sheet of discharging opening, the size that discharging opening is sealed by the tightness of squeeze handles come controlling switch inserted sheet,
The control to flowing out solution speed is realized, the subpackage efficiency and operation ease of experiment solution is improved.
2nd, due to being furnished with lid on the charging aperture of container body, aperture is provided with lid, can be in the state of approximate closing
The reagent solution such as quantitative separating is volatile, oxidizable, hygroscopic, inflammable, perishable, explosive, hypertoxic, carcinogenic, pathogenic.
3rd, as container body is made up of clear glass, surface indicates volume markings, can be while subpackage, accurate assurance
The volume that subpackage solution flows out.
Description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the structural representation of support of the present invention.
Specific embodiment
Below in conjunction with attached Example, the invention will be further described：
The present invention as shown in Figure 1, is provided with the container body that charging aperture and bottom are provided with discharging opening including top, and container body is column
Body, container body are made up of epimere 1-1, stage casing 1-2 and hypomere 1-3, and three sections of diameter ratio is 4:2:1, container body is clear glass
Make, container body is marked with volume markings 2, the container is externally provided with fixed handle 3, the top of fixed handle connection container body and
Bottom, is provided with flexible handle 4 between fixed handle 3 and container body, 4 top of flexible handle is fixed with 3 top of fixed handle, activity
Shell fragment 10 is crimped between the top of handle 4 and fixed handle 3, is provided with pressure between 3 hypomere of 4 hypomere of flexible handle and fixed handle
Contracting spring 5, the bottom of flexible handle 4 are provided with the switch inserted sheet 6 for stretching into container body bottom and sealing discharging opening, the switch inserted sheet from
The socket insertion that container body bottom side is provided with；The charging aperture of container body is provided with lid 11, and the edge of the lid is provided with aperture
7, water dropper 8 is connected under discharging opening, the pore size of aperture 7 is identical with 8 size of water dropper, instrument internal when can avoid solution subpackage
There is vacuum；Water dropper 8 is spirally connected with discharging opening, and the water dropper is made up of glass material, detachable, replaceable, should be arranged using before
Gas.
As shown in Fig. 2 container body is erected in support 9, the support is made up of upper and lower two rings 9-1 and 9-2, upper ring 9-1
Internal diameter is less than lower ring 9-2 internal diameters, and upper ring 9-1 is connected by three symmetrically arranged support feets 9-3 with lower ring 9-2, container body
, on the upper ring of support, hypomere is stretched in ring for epimere and stage casing frame, makes container body suspension frame on the support, when quantitatively will dividing
When filling the reagent solution such as volatile, oxidizable, hygroscopic, inflammable, perishable, explosive, hypertoxic, carcinogenic, pathogenic, solution is poured into
In dispenser, close the lid, when outwards promptly flexible handle, switch inserted sheet is pulled out, and leaves discharging opening, and solution is from discharging opening stream
Go out, when flexible handle is unclamped, the switch inserted sheet of flexible handle and its connection sets back in the presence of shell fragment and spring,
Discharging opening is blocked, and prevents solution from flowing out, and by the tightness of Compressive activities handle come the size of controlling switch, is realized to flowing out
The control of solution speed.
