Description
Technical field
The utility model is related to chemical experiment technique field, specially a kind of reaction tube for chemical experiment teaching.
Background technology
At present, in senior middle school or college days, experiment can be run into unavoidably, and test in order to whole process is presented into student
Viewing, all indoors, and can relatively enter apart from student, and some experiments are that have dangerous, particularly chemical experiment, due to big portion
All in vitro portion is carried out to divide chemical experiment, and general test tube is only one group of transparent vial, due in test tube
The space in portion is limited, so the gas produced during raw material reaction is directly discharged in air, with larger potential safety hazard.
The content of the invention
The purpose of this utility model is to provide a kind of reaction tube for chemical experiment teaching, to solve above-mentioned background
The problem proposed in technology.
To achieve the above object, the utility model provides following technical scheme：A kind of reaction for chemical experiment teaching
Test tube, including test tube housing, cirque structure, reaction interval, gas housing, pour into pipeline, gas storage interval, rubber stopper,
Through-hole structure, check valve and hinge, the bottom of the test tube housing are provided with cirque structure, the test tube housing and annular knot
The center of structure is equipped with reaction interval, and one group of gas housing, the top of the test tube housing are fixed on the body of rod of the test tube housing
Portion fixes one group and pours into pipeline, and the top of the gas housing is fixed with the top for pouring into pipeline, described to pour into pipeline, examination
The interval gas that formed of sealing formed between the gentle body shell body of tube shell stores interval, between the gentle body shell body of test tube housing
Be provided with one group of through-hole structure, the inside of the through-hole structure positioned at the inside of gas housing by hinge fix one group it is unidirectional
Insert one group of rubber stopper in valve, the top for pouring into pipeline.
Preferably, the hinge is angle rotary structure.
Preferably, the through-hole structure is " L " shape structure.
Preferably, the check valve is in horizontality.
Preferably, it is provided with control valve in the gas storage interval.
Compared with prior art, the beneficial effects of the utility model are：The utility model simple structure, sets up independent gas
Body storage area, can by raw material reaction when, the toxic gas of generation is effectively stored, so as to effectively prevent toxic gas
It is directly discharged to outdoor.
Brief description of the drawings
Fig. 1 is a kind of structural representation of reaction tube for chemical experiment teaching of the utility model；
In figure：1. test tube housing, 2. cirque structure, 3. reaction interval, 4. gas housing, 5. pours into pipeline, 6. gas
Storage is interval, 7. rubber stopper, 8. through-hole structure, 9. check valve, 10. hinge.
Specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of the utility model protection.
Refer to Fig. 1, a kind of embodiment that the utility model is provided：A kind of reaction tube for chemical experiment teaching,
Including test tube housing 1, cirque structure 2, reaction interval 3, gas housing 4, pour into pipeline 5, gas storage interval 6, rubber stopper
7th, through-hole structure 8, check valve 9 and hinge 10, the bottom of the test tube housing 1 are provided with cirque structure 2, the test tube housing 1
Reaction interval 3 is equipped with the center of cirque structure 2, one group of gas housing 4, institute are fixed on the body of rod of the test tube housing 1
The top for stating test tube housing 1 fixes one group and pours into pipeline 5, and the top of the gas housing 4 is solid with the top for pouring into pipeline 5
Fixed, the sealing interval formed between the gentle body shell body 4 of pipeline 5, test tube housing 1 of pouring into forms gas storage interval 6, described
One group of through-hole structure 8 is provided between the gentle body shell body 4 of test tube housing 1, the inside of the through-hole structure 8 is positioned at gas housing 4
Inside one group of check valve 9 is fixed by hinge 10, one group of rubber stopper 7 is inserted at the top for pouring into pipeline 5；The hinge 10
It is angle rotary structure；The through-hole structure 8 is " L " shape structure；The check valve 9 is in horizontality；The gas storage
Control valve is provided with depositing interval 6.
Specifically used mode：In utility model works, reactant is poured into the inside of test tube housing 1 together, and will
Rubber stopper 7 is inserted into import pipe 5, and during reaction, because reactant produces substantial amounts of gas, these gases can be by through hole knot
