The technical solution of the utility model is as follows:
A kind of porous tubular aerator supporting tube, comprises saddle Connection Block 1 and straight tube cylindrical shell 2, it is characterized in that:
Have two grooves distributed vertically 3 outside described straight tube cylindrical shell 2, groove 3 end has an annular to dash forward muscle 4, and the cross section of the both-side ends cylindrical shell of straight tube cylindrical shell 2 is full circle, and there is seal plug 6 straight tube cylindrical shell 2 inside, straight tube cylindrical shell 2 has ventilating pit 9;
Described saddle Connection Block 1 is semicircular structure, and turning pin shaft hole 5 is established in one end, and the other end establishes two stainless steel bolt connecting holes, and positioning boss 7 is established in a stainless steel bolt connection hole wherein, establishes detent 8 in another stainless steel bolt junction.
The utility model is all right further preferably by the following technical solutions:
Described groove 3 degree of depth is 1.5 ~ 2.5mm.
Described groove 3 is symmetrical arranged outside straight tube cylindrical shell 2.
Described annular dashes forward muscle 4 highly for 1mm.
Described positioning boss 7 and detent 8 are about porous tubular aerator supporting tube centerplane symmetry.
There is hex hd counterbore 10 at described positioning boss 7 back.
Described saddle Connection Block 1 and straight tube cylindrical shell 2 material be made from polypropylene.
The utility model has following beneficial effect:
Porous tubular aerator supporting tube stainless steel bolt of the present utility model is fixed, easy for installation, solid and reliable; Accurate positioning; The prominent muscle of two ends annular, makes sealing property better; Vent grooves designs, and make aeration even, aeration is effective, effectively improves the efficiency of aeration oxygen replenishing.
