Portion, thus it is inconvenient when mounted.
2, traditional spark plug guide pipe is not when in use due to having containment member so that the leakproofness of conduit is poor, is easy
Cause the micro leakage of fuel oil.
Utility model content
The purpose of this utility model is to provide a kind of automobile engine spark plug conduits, to solve in above-mentioned background technology
The problem of proposition.
To achieve the above object, the utility model provides the following technical solutions：A kind of automobile engine spark plug conduit, packet
External screw thread, rubber ring, conduit and interface are included, the tube at one end outer wall is fixedly installed inclined-plane socket, and the conduit is separate
Outer wall fixation in inclined-plane socket one end offers external screw thread, and the conduit outer wall is fixedly attached that there are four sealings close to external screw thread side
Circle, the conduit outer wall are located at sealing ring and are connected to retainer plate far from external screw thread side fixing sleeve, and the sealing ring passes through retainer plate
It is fixedly mounted on conduit outer wall；The conduit offers internal thread far from the fixation of inclined-plane socket one end inner wall, and the conduit is separate
Inclined-plane socket one end is fixedly welded with interface, and the interface inner wall has rubber pad with conduit connection fixed placement, described
Interface outer wall is fixedly welded with knob block.
Further, the interface is fixedly installed inclined-plane far from tube at one end inner wall.
Further, external screw thread section outer diameter is more than conduit section outer diameter, and external screw thread section outer diameter
Size is identical as sealing ring outer diameter.
Further, the internal thread is matched with spark plug.
Further, the external screw thread is matched with guide hole inner wall.
Compared with prior art, the utility model has the beneficial effects that：
1, by offering external screw thread in conduit outer wall fixation, and external screw thread is matched with guide hole inner wall, convenient for utilizing
Conduit is mounted on inside guide hole by external screw thread so that easier for installation for the more traditional conduit of the utility model.
2, by being placed with rubber pad with conduit connection inside interface, convenient for will be carried out between spark plug and conduit
Sealing, by being socketed with sealing ring in conduit outer wall, and sealing ring mutually agrees with guide hole inner wall, convenient for conduit and guide hole
Inner wall is sealed.
