[0025] Example 1
[0026] like Figure 2 As shown, this embodiment discloses an electric hot-melt joint, which includes a joint body 1 and an annular boss 2 arranged inside the joint body 1. The joint body 1 is a section of pipe, and the annular boss 2 is annularly protruding toward the central axis of the joint body 1, so that the annular boss 2 divides the interior of the joint body 1 into two socket cavities 4 along the axial direction, and the two socket cavities 4 are connected through the internal channel of the annular boss 2. In the specific setting, the joint body 1 and the annular boss 2 are integrally injection molded, and the annular boss 2 is located in the middle of the joint body 1, so that the two socket cavities 4 have the same length. In this embodiment, the joint body 1 and the annular boss 2 are both made of polyethylene material.
[0027] In addition, a heating wire 3 is embedded in the cavity wall of the socket cavity 4 and the inner wall of the annular boss 2 . Both ends of the heating wire 3 are connected to electrodes 5 . Both electrodes 5 pass through the connector body 1 and extend out of the connector body 1 .
[0028] In a specific configuration, the heating wire 3 can be helically embedded in the cavity wall of the socket cavity 4 and the inner wall of the annular boss 2. Alternatively, the heating wire 3 can be axially folded back and embedded in the cavity wall of the socket cavity 4 and the inner wall of the annular boss 2. That is, the heating wire 3 extends axially along the socket cavity 4 and the annular boss 2 and is folded back and forth circumferentially distributed in the cavity wall of the socket cavity 4 and the inner wall of the annular boss 2. In this embodiment, the heating wire 3 is helically embedded in the cavity wall of the socket cavity 4 and the inner wall of the annular boss 2.
[0029] When in use, the heating wire 3 is energized through the two electrodes 5 to generate heat, and the cavity wall of the socket cavity 4 and the inner wall of the annular boss 2 are softened, thereby being welded to the pipe inserted therein.
[0030] Example 2
[0031] This embodiment discloses a pipeline system, which includes a plurality of pipelines, and two adjacent pipelines are connected by the electric hot-melt joint in Example 1.
[0032] Specifically, the connecting end of the pipe is provided with a socket 9. The diameter of the pipe matches the diameter of the socket cavity 4, and the diameter of the socket 9 matches the diameter of the internal channel of the annular boss 2. When connecting, the connecting ends of two adjacent pipes are respectively inserted into the two socket cavities 4 of the same joint body 1 and welded to the cavity walls of the two socket cavities 4. At the same time, the sockets 9 of both pipes are inserted into the interior of the annular boss 2 and welded to the inner wall of the annular boss 2.
[0033] In addition, the length of the annular boss 2 is the same as the total length of the sockets 9 on the two pipes. Therefore, when the two pipes are respectively inserted into the two socket cavities 4 and the ends thereof are respectively against the two sides of the annular boss 2, the ends of the two sockets 9 are just butted together. Figure 4 shown.
[0034] The pipe may be a polyethylene pipe, and an annular concave platform may be cut out at the connecting end of the polyethylene pipe during processing. The annular concave platform is the socket plug 9 mentioned above.
[0035] In addition, if Figure 3 As shown in FIG. 1 , as another implementation, the pipe includes a polyethylene inner layer 6, a fiber reinforced layer 7 wrapped around the outer side of the polyethylene inner layer 6, and a polyethylene outer layer 8 wrapped around the outer side of the fiber reinforced layer 7. During processing, the length of the polyethylene inner layer 6 is longer than the lengths of the fiber reinforced layer 7 and the polyethylene outer layer 8, so that the end of the polyethylene inner layer 6 extends outside the fiber reinforced layer 7 and the polyethylene outer layer 8 to form the socket 9.
[0036] The fiber reinforcement layer 7 can be a basalt fiber layer or a glass fiber layer.
[0037] This embodiment can increase the connection and fixing area between the electric heat-melt joint and the two pipes, and improve the connection strength between the electric heat-melt joint and the two pipes.
[0038] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
[0039] In addition, the above-mentioned specific embodiments are merely illustrative.

Those skilled in the art should understand that the specification and drawings of this utility model are illustrative and do not constitute limitations of the claims.
