Abstract
The utility model relates to a connecting structure of a pipe, particularly to a connecting structure of a spinning pipe fitting, which structurally consists of a pipe joint, a pipe and a connecting nut, wherein an internal thread is arranged on an inner ring at the outer end of the pipe joint; an external thread matched with the internal thread is arranged on an outer ring of the connecting nut; the connecting nut is rotationally connected into the pipe joint; the pipe penetrates the connecting nut to be inserted into the pipe joint; an annular bulge is arranged on an outer ring at the end part of the pipe; the end part of the connecting nut is propped against the annular bulge; an annular groove is arranged on the outer side of the annular bulge; an O-shaped seal ring is arranged in the annular groove; a first annular oblique surface is arranged on an inner ring of the pipe joint; and the O-shaped seal ring is propped against the first annular oblique surface. The connecting structure of the pipe has simple structure, is convenient to use, and has satisfactory pulling-resistance and sealing performance, and reduces the production cost by adopting the O-shaped seal ring as a universal part.
Description
Technical field
The utility model relates to the linkage structure of pipe.
Background technique
Conventional pipelines and link thereof are threaded usually or groove type connects; Be connected firmly for reaching, tight, non-leakage purpose, need open hinge screw thread or open channels to tube end so that be connected, so just damaged, weakened the intensity of tube end with internal thread or groove, directly influence the anti-pull performance of pipe connection.In addition, and the direct employing of link is threaded or groove type is connected for pipe, and pipe is not fine with the sealing that is connected of link, occurs easily leaking yet.Also have, just save the material aspect and consider that the Placement of spinning type pipe fitting suitably reduces wall thickness under the prerequisite that satisfies pipe intensity, help controlling cost, improve the competitiveness of product in market.
Summary of the invention
In order to solve above-mentioned pipe Placement anti-pull and the bad technological deficiency of sealability; The purpose of the utility model provides a kind of linkage structure of spinning type pipe fitting; This structure has all characteristics preferably of anti-pull and sealability, has reduced production cost simultaneously.
In order to realize above-mentioned purpose, the technological scheme below the utility model has adopted:
The linkage structure of spinning type pipe fitting, this structure is made up of pipe joint, pipe and attaching nut, and the outer end inner ring of described pipe joint is provided with internal thread; Attaching nut's outer ring is provided with the outside thread that matches with internal thread, and the attaching nut is screwed in the pipe joint, and described pipe passes the attaching nut and is plugged in the pipe joint; The outer ring, end of pipe is provided with annular protrusion; Attaching nut's end and described annular protrusion offset, and are provided with circular groove in the outside of annular protrusion, are provided with the O RunddichtringO in the circular groove; And being provided with first annular slope at the inner ring of pipe joint, the O RunddichtringO and first annular slope offset.
As further improvement, the outside of described annular protrusion is second annular slope, and inner ring is provided with the 3rd annular slope in attaching nut's end, and attaching nut's end and described annular protrusion offset through second annular slope and the 3rd annular slope.
As further improvement, described pipe is a metal tube, and described annular protrusion and circular groove form through extruding or diffusion.
As further improvement, the inner ring inboard of described pipe joint is provided with the protruding circle of annular stop.The protruding circle of annular stop can be used to stop the pipe axial motion.
Above-mentioned pipe joint is isometrical straight tube, 45 ° of bend pipes or 90 ° of bend pipes; Perhaps, pipe joint is the straight tube of reducing, 45 ° of bend pipes or 90 ° of bend pipes; Certainly, pipe joint also can be straight tee, reducer tee piece, straight cross pipe or reducing cross pipe.
The utility model has been owing to adopted above-mentioned technological scheme, after pipe is inserted into pipe joint, and the attaching nut that screws, attaching nut's end roof pressure annular protrusion closely cooperates O RunddichtringO and first annular slope in the circular groove, realizes sealing.The utlity model has simple in structurely, easy to use, anti-pull and sealability be characteristics preferably all, and adopting the O RunddichtringO is universal component, has reduced production cost.
