In above-mentioned pipe fitting joint; Said sealed nut is inner to be connected with above-mentioned casing threads; Described compressing structure be sealed nut outer end to retaining edge of its inboard protrusion be used to be enclosed within the pressure ring on the pipe fitting, the two ends of pressure ring can contact with the retaining edge with cannula tip respectively.
In the process that sealed nut and sleeve pipe spin, sealed nut to the middle part of sleeve pipe near, pressure ring was under pressure and produced deformation this moment, and pipe fitting is locked.Since pipe fitting cannula tip and retaining along between, and sealed nut is connected with casing threads, after pipe fitting is locked by pressure ring, the characteristics that have difficult drop-off, are connected firmly.
In above-mentioned pipe fitting joint, described rotation section is the driven gear in the sealed nut outside.Be provided with like this and make things convenient for the operation of instrument sealed nut.
In above-mentioned pipe fitting joint, described sleeve port place has chamfering, and described sealed nut retaining has chamfering along the inner, and guide portion and guide portion that above-mentioned pressure ring two ends all have inclination can contact with above-mentioned chamfering.
The purpose that is provided with like this is, in the process of the sealed nut of precession, the power of this pressure ring converted sleeve pipe and sealed nut the impacting force of pressure ring to pipe fitting into, makes things convenient for pressure ring generation deformation, and pipe fitting is had better impacting force.
In above-mentioned pipe fitting joint, described sleeve pipe inboard has the position limiting convex ring of protrusion.
Position limiting convex ring mainly plays the role of positioning to the pipe fitting that is inserted in the sleeve pipe, and when connection was installed, the end that is inserted into the two pipe fittings in the sleeve pipe can be resisted against respectively on this position limiting convex ring, reaches the purpose of location.
In above-mentioned pipe fitting joint, described pressure ring adopts softer metals to process.
The purpose that is provided with like this is, makes things convenient for pressure ring to be under pressure back and generation deformation.
In above-mentioned pipe fitting joint, described pressure ring adopts aluminium material to process.
In above-mentioned pipe fitting joint, described pressure ring adopts brass material to process.
Compared with prior art, this pipe fitting joint has the following advantages:
Simple in structure and the operation of this pipe fitting joint and easily manufactured need not be provided with screw thread on joint, reduced the manufacture difficulty and the manufacture cost of pipe fitting.The pressure of pressure ring is converted sealed nut the impacting force of pressure ring to pipe fitting into, through the instrument sealed nut that spins, simple to operate, easy realization.Pressure ring adopts softer metals to process, and the deformation quantity of soft metal is big, and the impacting force of butt joint is just big more, connects back joint difficult drop-off, good stability.
