Abstract
The utility model discloses an inner pressed clipping type connecting fitting of a belled mouth. The utility model comprises two metal pipes, internal screw caps, nuts, sealing rings, and lining cores, and is characterized in that the ends of the metal pipes adopt the bell-like mouths, and bevel faces matched with the belled mouth are arranged at the both ends of the lining core, and respectively jointed with the belled mouths at the ends of the two metal pipes; the seal rings are arranged between the bevel faces of the lining cores and the belled mouths of the metal pipes; bevel faces matched with the belled mouths of the metal pipes are arranged on the inner walls of the internal screw caps, and sleeved on the belled mouths of the metal pipes, and the other ends are connected with the internal screw caps in a screw way. Wrench toothed mouths are arranged in the inner screw caps. The utility model has the advantages that the structure is reasonable and novel, the cost is low, the installation is easy, the connection is tight and is not easy to be dropped out, and the utility model is particularly suitable for connecting the metal pipes with small diameter and thin wall.
Description
Technical field
The utility model relates to a kind of thin-wall metal pipe connected pipe fitting, is horn mouth internal thread pressure-cliping connection pipe fitting.
Background technique
What extensively adopt on the market at present, is clamp-press type connection pipe fitting and socket connection pipe fitting.Clamp-press type need use special instrument, and the wall thickness of tubing is had requirement; Plug-in type is more complicated then, and cost is higher.
Summary of the invention
For addressing the above problem, the utility model provides a kind of horn mouth internal thread pressure-cliping connection pipe fitting simple in structure, easy for installation, this model utility comprises metal tube, interior nut, nut, seal ring, lining core, it is characterized in that, described metal tube termination is a horn mouth, described lining core two ends are equipped with the inclined-plane with the horn mouth coupling, and engage with the horn mouth of two metal tube terminations respectively; Be provided with seal ring between described lining core inclined-plane and the metal tube horn mouth; The nut inwall is provided with the inclined-plane that mates with the metal tube horn mouth in described, and is placed on the horn mouth of metal tube; Described nut inner wall one end is provided with the inclined-plane with metal tube horn mouth coupling, and is placed on the horn mouth of metal tube, and the other end is connected with interior nut screwing.
Nut is provided with spanner tooth mouth in described.
Described seal ring has gradient.
Because said structure, the utility model possesses following advantage: rational in infrastructure, ingenious, cost is low, installs and need not use special tool(s) easily, connects tight difficult drop-off.
