Preferably, the coni card buckles surface diameter R, lower surface diameter r, R=1.2r, orifice diameter 1.1r, circle
Cone buckle is equal to its bottom thickness H with chain extension bar junction height h.
Compared with prior art, the beneficial effects of the utility model are：A kind of extraction for the detection of underground gas and liquid collecting
Device is simple in construction, easy to process, and cost is cheap, easy to operate, and volume is light and handy, easy to carry, can prevent liquid in sampler
Leaked in transportation, and liquid is good with outside air isolation performance in sampler, and it is empty with the external world that water sample can be greatly decreased
The time of contact of gas and chance, make detection and analysis data more accurate.
Further advantage, target and feature of the present utility model embody part by following explanation, and part will also pass through
Research of the present utility model and practice are understood by the person skilled in the art.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, 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 obtained, belong to the scope of the utility model protection.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein are not precluded from one or more
The presence or addition of individual other elements or its combination.
Fig. 1-7 are referred to, the utility model provides a kind of technical scheme：A kind of extraction for the detection of underground gas and liquid collecting
Device, including body 3, rubber leakage-proof cover 1, circular cone buckle 5, pull bar 8, mouth of pipe plug 6, the bottom of body 3 have two symmetrically
Aperture 9, the bottom outer wall of body 3 are provided with symmetrical slideway 4, and the rubber leakage-proof cover 1 is arranged on the top of chain extension bar 2, and links
