In a preferred embodiment of the present invention, an inner wire metal ring is embedded on the inner wall of the external connection mounting hole, and a threaded mounting portion is provided on the inner wall of the inner wire metal ring.

In a preferred embodiment of the present invention, the outer wall of the inner wire metal ring is formed with a skirt protruding outward.

In a preferred embodiment of the present invention, the length of the vertical flow passage is greater than the length of the horizontal flow passage, so that the inner wire interface end plane has a sufficient distance from the center line of the horizontal pipe.

In a preferred embodiment of the present invention, the horizontal tube and the vertical tube are integrally formed.

The beneficial effects of the utility model reside in that:

compared with the prior art, the utility model provides a pair of extension internal thread elbow pipe fitting, simple structure is reasonable, convenient to use, internal thread interface end plane on the standpipe with violently manage the central line and be provided with sufficient distance, guarantee that internal thread interface can normally expose outside the wall body.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention. Moreover, in the following structures, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top/bottom", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, and are only for convenience of description of the present invention and simplification of description. And are not intended to indicate or imply that the device or element so referred to must have a particular orientation, be constructed and operated in a particular orientation and are therefore not to be considered limiting of the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The lengthened internal thread elbow pipe fitting 100 shown in fig. 1 or 2 comprises a vertical pipe 110, wherein a vertical flow passage 111 is arranged inside the vertical pipe 110, the vertical pipe 110 is communicated with a transverse flow passage 121 formed inside a transverse pipe 120 through the vertical flow passage 111, in addition, a flared bell and spigot 130 communicated with the transverse flow passage 121 is arranged at the tail end of the transverse pipe 120, and the flared bell and spigot 130 comprises an inner port 131 and an outer port 132 which are connected; the diameter of outer port 132 is greater than the diameter of interior port 131, and interior port 131 diameter is greater than the diameter of horizontal runner 121, and is provided with fillet 133 on the mouth edge of interior port 131, and fillet 133 has the guide effect, can make things convenient for the socket and spigot joint.

And standpipe 110 and violently pipe 120 adopt integrated into one piece, simple structure, connect reliably.

An internal screw connector 140 is mounted at the end of the vertical tube 110, and an external mounting hole 141 communicated with the vertical flow channel 111 is formed in the internal screw connector 140. A plurality of anti-slip ribs 150 are arranged on the outer periphery of the inner wire interface 140 in parallel at intervals. When the water-using terminal is installed in the external mounting hole 141, the internal screw interface 140 can be effectively held by the anti-slip ribs 150, so that the connection between the water-using terminal (not shown) and the internal screw interface 140 is ensured to be tight.
