Detailed Description

As shown in fig. 1 to 4, the present embodiment discloses a novel threaded pipe fitting, which includes a first threaded pipe 1, a second threaded pipe 2, and a connecting thread bush 3 for connecting the first threaded pipe 1 and the second threaded pipe 2; in this embodiment, the first threaded pipe 1 and the second threaded pipe 2 are stainless steel pipes, and may be other metal threaded pipes or plastic threaded pipes in specific implementation;

the end parts of the first threaded pipe 1 and the second threaded pipe 2, which are in mutual contact, are respectively provided with a thickened port 1a and a matched thickened port 2a, the first threaded pipe 1 and the thickened port 1a are integrally manufactured or welded, and the same port of the second threaded pipe 2 is also provided with a matched thickened port 2a, wherein the end part thickening structure is connected between the first threaded pipe 1 and the second threaded pipe 2, so that the situation that the connection of the threaded pipes is broken easily due to the fact that the end parts of the threaded pipes are locally thinned due to the fact that threads are arranged on the end parts of the threaded pipes is avoided; thickening port 1 a's external diameter with cooperation thickening port 2 a's external diameter is the same, thickening port 1a with cooperation thickening port 2 a's external diameter all is greater than first screwed pipe 1 and second screwed pipe 2's external diameter thickening port 1a with the external screw thread that sets up on the cooperation thickening port 2a is identical connection each other, thereby is convenient for connecting thread bush 3 wears to overlap and is in on the second screwed pipe 2 or on the first screwed pipe 1, when needing to connect, directly twist through the screw and connect, utilize first screwed pipe 1 with the reducing structure of 2 tip of second screwed pipe reduces connecting thread bush 3 is in on the second screwed pipe 2 or the length that first screwed on 1 screwed in out.

In the embodiment, the first threaded pipe 1 and the second threaded pipe 2 are connected through the connecting threaded sleeve 3, and in the installation process, the outer peripheries of the first threaded pipe 1 and the second threaded pipe 2 are provided with threads, so that when the connecting threaded sleeve 3 is in threaded connection, the end faces of the first threaded pipe 1 and the second threaded pipe 2 are in contact and easily dislocated, and a large gap exists between the first threaded pipe 1 and the second threaded pipe 2, so that the connection strength and the sealing property are affected; therefore, in this embodiment, a plurality of inserting protrusions 1b are integrally formed on the end surface of the thickened port 1a along the axial direction thereof, a reserved matching groove 2b matched with the inserting protrusion 1b in an inserting manner is formed on the end surface of the matched thickened port 2a, and the inserting protrusion 1b is adapted to the reserved matching groove 2b in an inserting manner, so that the positioning operation is completed, the connecting thread sleeve 3 is conveniently installed on the first threaded pipe 1 and the second threaded pipe 2, in this embodiment, 3 inserting protrusions 1b are integrally formed on the end surface of the thickened port 1a along the axial direction thereof, three inserting matching grooves 2b matched with each other are correspondingly formed on the end surface of the second threaded pipe 2, so that the inserting protrusions 1b are engaged with the reserved matching grooves 2b in an inserting manner, thereby improving the connection strength and preventing the connection end from being broken;

as shown in fig. 5, the peripheries of the thickened port 1a and the matching thickened port 2a are respectively provided with an external thread groove, the connecting thread bush 3 is provided with an internal thread matched with the thickened port 1a and the matching thickened port 2a, the periphery of the connecting thread bush 3 is provided with a friction stripe 3a convenient for threaded connection, and the friction stripe 3a is parallel to the axial direction of the connecting thread bush 3; when the connecting threaded sleeve 3 is installed, the belt can be screwed through large friction force, and the connecting threaded sleeve 3 can be driven to be in threaded connection with the first threaded pipe 1 and the second threaded pipe 2.
