Preferably, one end or movable joint fixing seat towards connecting tube of the chuck are equipped with externally threaded one end and are equipped with annularGroove and with the matched sealing ring of annular groove.
Preferably, one end or movable joint fixing seat towards connecting tube of the chuck are equipped with externally threaded one end and are equipped with and instituteThe opposite annular convex platform of annular groove is stated, the size of annular groove is greater than with the annular convex platform size.
Preferably, the internal diameter of the intake section is greater than the internal diameter of connecting tube, the inner wall of intake section and the inner wall of connecting tubeJunction is funnel-shaped.
Preferably, the intake section is equipped with the water pipe to match with its internal diameter.
Preferably, the connecting tube is connected with matched for being connected to the connector of aeration tube with its size.
Preferably, the connector is pagoda connector.
A kind of aeration tube leakproof described in the utility model just dismounts connection structure, the advantage is that, structure is simple, installationConvenient, connection is reliable, only need to outside cultivation equipment energy quick-replaceable gas pipeline, reduce needs and be manually entered cultivation and setThe risk of standby bottom operation replacement pipeline operations, ensure that the normal work of aeration tube.

Specific embodiment
As shown in Figure 1, it includes internal run-through that a kind of aeration tube leakproof described in the utility model, which just dismounts connection structure,The movable joint sliding seat 200 of movable joint fixing seat 300, movable joint traveling nut 100 and internal run-through；The movable joint fixing seat 300One end side wall is equipped with external screw thread, and the other end is embedded or is welded on cultivation equipment edge bottom, penetrates through with cultivation equipment.The workThe external screw thread of the internal screw thread and the movable joint fixing seat 300 that save traveling nut 100 cooperates, and one end of movable joint traveling nut 100 is setThere is through-hole diameter to be less than the fixed part (101) of its internal screw thread nominal diameter；The cylindrical intake section of the movable joint sliding seat 200201 connect with gas pipeline, and cylindrical connecting tube 202 is connect with aeration tube；Chuck is equipped between intake section 201 and connecting tube 202203,203 outer diameter of chuck is between the through-hole diameter and its internal screw thread nominal diameter of movable joint traveling nut 100；The chuck203 one end or movable joint fixing seat 300 towards connecting tube 202 be equipped with externally threaded one end be equipped with annular groove 301 and with annularThe matched sealing ring 400 of groove 301.In the present embodiment, the setting of annular groove 301 is equipped with externally threaded in movable joint fixing seat 300One end, correspondingly, annular convex platform 204 is provided with towards one end of connecting tube 202 in chuck 203, with the annular convex platform 204Size is greater than the size of annular groove 301.Sealing ring 400 in 204 part of boss and annular groove 301 can effectively increase pipeThe leakproofness of road connection, prevents the phenomenon for causing aeration quantity deficiency occur because airtightness is bad.The movable joint sliding seat 200Connecting tube 202 puts in the inner hole of movable joint fixing seat 300, the one end of chuck 203 towards connecting tube 202 and and movable joint fixing seat 300It is connected to each other equipped with externally threaded one end, the intake section 201 of movable joint sliding seat 200 passes through movable joint traveling nut 100, by chuck 203It is stuck between movable joint traveling nut 100 and movable joint fixing seat 300.
The internal diameter of the intake section 201 is greater than the internal diameter of connecting tube 202, the inner wall of intake section 201 and connecting tube 202Inner wall junction is funnel-shaped.By this structure, thus it is possible to vary the sectional area that the gas in gas pipeline passes through, when sectional area becomesHour, pressure increases, to enhance aeration intensity.Funnelform structure has certain buffer function, avoids suddenly changeSectional area is corresponding to generate excessive gas transmission resistance.
The intake section 201 is equipped with the water pipe to match with its internal diameter, and the ruler of intake section 201 is adjusted using the water pipeIt is very little, achieve the purpose that the size for adapting to a variety of gas pipelines.
The connecting tube 202 of the movable joint sliding seat 200 is connected with matched for being connected to the company of aeration tube with its sizeFitting 500.The connector 500 is pagoda connector.Pagoda connector can easily be connect with aeration tube, and easy to disassemble.
For those skilled in the art, it can make other each according to the above description of the technical scheme and ideasThe corresponding change of kind and deformation, and all these changes and deformation all should belong to the guarantor of the utility model claimsWithin the scope of shield.
