As a further alternative, the end of the inner circular surface of the large diameter tube remote from the end plate has a guide slope.
As a further alternative, the outer circumferential surface of the large-diameter pipe is provided with a plurality of reinforcing ribs.
As a further alternative, the reinforcing rib is annular and is annularly arranged on the outer circular surface of the large-diameter pipe.
As a further alternative, the ribs may be triangular in cross-section.
As a further alternative, the length of the large diameter tube is no greater than the length of the small diameter tube.
The utility model has the advantages that: the interior disc of major diameter pipe and the outer disc interference fit of plastics inspection shaft branch pipe, the cooperation tightness is high, the path pipe corresponds in plastics inspection shaft branch pipe, only need during the installation with this reducer union's major diameter pipe for the excircle of plastics inspection shaft branch pipe embolia hard can, not only need extra rubber ring, the installation is simple moreover, the card cover can outside the plastics inspection shaft branch pipe, the manual operation degree of difficulty has been reduced, do benefit to the standardization, the complex tightness has been increased, the bearing strength of branch pipe has still been increased, and is waterproof, and the intensity is high.
