Furthermore, an annular limiting groove is formed in the top of the cover body and is matched with the connecting pipe.
Further, a sealing ring is arranged at the bottom of the limiting groove.
Furthermore, upward bumping posts are arranged around the through hole of the cover body.
Furthermore, a sieve plate is arranged between the cover body and the column body and is positioned at the top of the orifice of the column body.
Further, a sealing ring is arranged at the bottom of the opening of the cover body, and the sealing ring is sleeved at the pipe orifice of the cylinder body.
The utility model has the advantages that: the utility model discloses can carry out quick dismantlement and installation, the fore-set bottom that connects simultaneously is provided with annular recess, and the lid top is provided with annular spacing groove, guarantees the sealed reliability of this chromatographic column joint department.
