Accurately.
For the problems in the relevant technologies, currently no effective solution has been proposed.
Utility model content
For above-mentioned technical problem in the related technology, the utility model proposes a kind of base burets, are able to solve
State technical problem.
To realize the above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of base buret, including with graduated liquid storage bottle, the lower end of the liquid storage bottle, which is integrally formed, to be connected with directly
Siphunculus, the upper end of the straight pipe are connected to the liquid storage bottle, and the lower end of the straight pipe is connected with soft tube, the straight pipe
Upside, which is connected with, to be in charge of, and described one end being in charge of is connected to the straight pipe, and the other end being in charge of is communicated with the atmosphere, described
Speed regulation device is connected on soft tube, the speed regulation device includes the wedge structure being arranged on the soft tube, the wedge shape
Idler wheel is connected in structure, the lower end of the soft tube is connected with needle-shaped liquid outlet.
Further, the liquid storage bottle upper end is equipped with bottle cap.
The utility model has the beneficial effects that controlling drop by way of using wedge structure and idler wheel cooperation on soft tube
Constant speed degree, it is easy to operate, it is easy to control.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without creative efforts, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is a kind of structural schematic diagram of base buret according to the utility model embodiment;
Fig. 2 is a kind of structural schematic diagram of the speed regulation device of base buret according to the utility model embodiment.
In figure: 1. liquid storage bottles;2. straight pipe;3. soft tube;4. wedge structure;5. idler wheel;6. bottle cap;7. point
Pipe;8. liquid outlet.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
As shown in Figs. 1-2, a kind of base buret according to the utility model embodiment, including with graduated storage
Liquid bottle 1, the lower end of the liquid storage bottle 1, which is integrally formed, is connected with straight pipe 2, and the upper end of the straight pipe 2 and the liquid storage bottle 1 connect
Logical, the lower end of the straight pipe 2 is connected with soft tube 3, is connected on the upside of the straight pipe 2 and is in charge of 7, it is described be in charge of 7 one end
It is connected to the straight pipe 2,7 other end be in charge of is communicated with the atmosphere, and is connected with speed regulation device on the soft tube 3, institute
Stating speed regulation device includes the wedge structure 4 being arranged on the soft tube 3, and idler wheel 5 is connected on the wedge structure 4, described
The lower end of soft tube 3 is connected with needle-shaped liquid outlet 8.
1 upper end of liquid storage bottle is equipped with bottle cap 6.
In order to facilitate the above-mentioned technical proposal for understanding the utility model, below by way of practical new to this in specifically used mode
The above-mentioned technical proposal of type is described in detail.
When specifically used, according to a kind of base buret described in the utility model, including with graduated liquid storage bottle
1, as long as the planform of liquid storage bottle 1 there is no limit can accurately measure its volume, straight pipe 2, soft tube 3, it is needle-shaped go out
The total volume of liquid mouth 8 be it is fixed, 2 one end of straight pipe is connected to liquid storage bottle 1, and the upside of straight pipe 2 connects one and is in charge of 7, point
Pipe 7 is communicated with the atmosphere, and then can export the solution of liquid storage bottle 1, and the other end of straight pipe 2 is connect with soft tube 3, operator
It can be scrolled up and down by the idler wheel 5 of speed regulation device, cooperate with wedge structure 4 and squeeze soft tube 3, squeeze the difference of soft tube 3
Degree realizes the control of rate of titration, easy to operate, even beginner is also easy to grasp, soft tube 3 and needle-shaped liquid outlet
8 connections, can effectively control out the amount of liquid, big drop has been avoided to ooze.Soft tube 3 can use rubber material.
When in use, liquid storage bottle 1 can be fixed on the support frame, soft tube 3 can also arbitrarily change the direction of titration,
Subtract the total volume as titration of straight pipe 2, soft tube 3, needle-shaped liquid outlet 8 again by the volume differences of titration front and back liquid storage bottle 1
Volume.
In conclusion by means of the above-mentioned technical proposal of the utility model, by used on soft tube wedge structure with
The mode of idler wheel cooperation controls rate of titration, easy to operate, easy to control.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
