Description

A kind of use for laboratory liquid getting device
Technical field
The present invention relates to a kind of use for laboratory liquid getting device.
Background technology
Laboratory carry out chemical experiment when, it is necessary to by liquid getting device carry out two kinds of solution mixing, commonly use dropper, drip Pipe is relatively low due to length, if running into the deep container of depth, general dropper length not enough, then can not smoothly get liquid, and And general liquid getting device is all straight tube shape, when in use, easily there is the situation of skating.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of adjustable length, are affectedly bashful and more comfortably, more stablize, set The more novel use for laboratory liquid getting device of meter.
The present invention is achieved through the following technical solutions:A kind of use for laboratory liquid getting device, including the first connecting tube, Two connecting tubes and the 3rd connecting tube, the second connecting tube are an arc tube, and one end of arc tube connects the first connecting tube, arc tube The other end connects the 3rd connecting tube, and the first connecting tube is parallel with the 3rd connecting tube;
First connecting tube, the second connecting tube and the conducting of the 3rd connecting tube, the inside of the first connecting tube offers a movable chamber, first An air intake passage is provided with connecting tube, the second connecting tube and the 3rd connecting tube;
One liquid flowing tube is set in movable chamber, and the top outer end of liquid flowing tube is provided with sealing ring, and sealing ring seals whole movable chamber;
The taking liquid passage opened up in liquid flowing tube is communicated with movable chamber upper end, and a getter device is set in the 3rd connecting tube.
As preferred technical scheme, the getter device includes a pumping rod, and the head of pumping rod sets a sealing-plug, Sealing-plug is filled in in the 3rd connecting tube, and pumping rod outboard end stretches out in the outside of the 3rd connecting tube.
As preferred technical scheme, limited block is provided with the air intake passage of the 3rd connecting tube, limited block is set In exit.
As preferred technical scheme, the arc tube is " U " type pipe.
The beneficial effects of the invention are as follows:The present invention is simple in construction, when in use, to adjust can take liquid according to the depth of container The length of pipe, and then be more beneficial for taking liquid, and the present invention is by setting a U-tube, therefore can easily be taken when taking liquid Pinch, be unlikely to skid, novel in appearance is reasonable in design, and use is more comfortable.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is overall structure diagram of the invention.
Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive Feature and/or step beyond, can combine in any way.
This specification(Including any accessory claim, summary and accompanying drawing)Disclosed in any feature, except non-specifically is chatted State, can alternative features equivalent by other or with similar purpose replaced.I.e., unless specifically stated otherwise, each feature It is an example in a series of equivalent or similar characteristics.
As shown in figure 1, a kind of use for laboratory liquid getting device of the present invention, including the first connecting tube 3, the second connecting tube 5 and the Three connecting tubes 6, the second connecting tube 5 is an arc tube, and one end of arc tube connects the first connecting tube 3, and the other end of arc tube connects The 3rd connecting tube 6 is connect, the first connecting tube 3 is parallel with the 3rd connecting tube 6;
First connecting tube 3, the second connecting tube 5 and the 3rd connecting tube 6 are turned on, and the inside of the first connecting tube 3 offers a movable chamber 4, an air intake passage is provided with the first connecting tube 3, the second connecting tube 5 and the 3rd connecting tube 6;
One liquid flowing tube 1 is set in movable chamber, and the top outer end of liquid flowing tube 1 is provided with sealing ring 2, and sealing ring 2 seals whole work Dynamic chamber;
The taking liquid passage opened up in liquid flowing tube 1 is communicated with the upper end of movable chamber 4, sets an air-breathing to fill in the 3rd connecting tube 6 Put.
Wherein, getter device includes a pumping rod 9, and the head of pumping rod 9 sets a sealing-plug 7, and sealing-plug 7 is filled in the In three connecting tubes 6, the outboard end of pumping rod 9 stretches out in the outside of the 3rd connecting tube 6.
According to the depth of container, the length of liquid flowing tube is adjusted, sealing ring plays a sealedly effect, when pumping rod is outside During pumping, by liquid flowing tube by the Liquid extracting of solution come completion takes liquid, and due to setting sealing ring, liquid flowing tube also will not be with Moving up and down for meaning, can only can be adjusted by pulling manually.
Limited block 8 is provided with the air intake passage of 3rd connecting tube, limited block 8 is arranged at exit, the effect of limited block 8 Mainly prevent sealing-plug to be drawn out the 3rd connecting tube, play a position-limiting action.
The arc tube 5 is " U " type pipe, when in use, and a finger can be buckled into U-type groove, facilitating whole liquid getting device Be affectedly bashful, be difficult skating.
The beneficial effects of the invention are as follows:The present invention is simple in construction, when in use, to adjust can take liquid according to the depth of container The length of pipe, and then be more beneficial for taking liquid, and the present invention is by setting a U-tube, therefore can easily be taken when taking liquid Pinch, be unlikely to skid, novel in appearance is reasonable in design, and use is more comfortable.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any The change or replacement expected without creative work, should all be included within the scope of the present invention.Therefore, it is of the invention Protection domain should be determined by the scope of protection defined in the claims.
