After the structure is adopted, the sealing ring is firstly sleeved in the connecting nut, the joint of the metal corrugated pipe of the gas appliance extends into the inner hole of the connecting nut from the right side of the connecting nut and is in threaded fit with the connecting nut, the socket joint extends into the inner hole of the connecting nut from the left side of the connecting nut, the socket joint penetrates through the sealing ring and extends into the joint of the metal corrugated pipe of the gas appliance, the sealing ring keeps the seal between the socket joint and the joint of the corrugated pipe, the limiting bolt extends into the inner hole of the limiting ring and abuts against the side wall of the socket joint, and the limiting bolt is matched with the convex rib of the socket joint to limit the axial position between the connecting nut and the socket joint.

The utility model has the advantages of: rational in infrastructure, connect closely, compare and use the sealing washer extrusion fixed among the prior art, this application uses the spacing structural constraint socket joint of machinery and gas utensil corrugated metal pipe's relative position, and after long-time the use, be connected between socket joint and the gas utensil corrugated metal pipe and can not become flexible, promote the security, stop the potential safety hazard, solved the pain point that prior art exists greatly.

The connecting nut of the gas green conversion joint extends a limiting ring to one side close to the socket joint, the inner diameter of the limiting ring is larger than the outer diameter of the socket joint, and the inner diameter of the limiting ring is smaller than the joint outer diameter of the metal corrugated pipe of a gas appliance; after the structure is adopted, the position of the sealing ring can be limited by the limiting ring, so that the sealing ring cannot slide out from the port of one side, close to the socket joint, of the connecting nut.

The side wall of the limiting ring of the connecting nut of the gas Green conversion joint is provided with a plurality of limiting threaded holes, the limiting threaded holes and the limiting bolts are in one-to-one correspondence, the limiting bolts are matched with the corresponding limiting threaded holes, and the plurality of limiting threaded holes are uniformly distributed along the axis of the limiting ring in a circumferential manner; after adopting such structure, spacing screw hole is more reasonable with spacing bolt's design, satisfies this gas green crossover sub's technical requirement.
