[0028] Implementation Method 1

[0029] Reference Figure 1 to Figure 2 This embodiment is an optional embodiment of the present application, which discloses an electric fusion pipe joint, including a pipe body 1, an external plug interface 2 is provided at one end of the pipe body 1, and an internal socket plug 3 is provided at the other end thereof;

[0030] The inner socket plug 3 is inserted into the connecting pipe during installation, and its outer wall is completely fitted with the inner wall of the connecting pipe. At the same time, a guide surface 7 is provided at the inlet end of the inner socket plug 3. The guide surface 7 is provided in a conical structure, and the large end of the guide surface 7 smoothly transitions to the inner wall of the connecting pipe.

[0031] Since the inner bell plug 3 of the present application will be inserted into the connecting pipe, and the pipe wall of the inner bell plug 3 has a certain thickness, the setting of the above-mentioned guide surface 7 can form a conical transition surface between the inner wall of the connecting pipe and the inner wall of the inner bell plug 3, which can make the liquid flow more smoothly on the one hand, and avoid the liquid from colliding violently with the end face of the plug pipe on the other hand.

[0032] It should be noted that the length of the internal plug connector is not less than 3 cm;

[0033] The inner wall of the external plug interface 2 is coaxially arranged with the inner wall of the internal socket plug 3, and the outer diameter of the end of the external plug interface 2 connected to the inner wall of the internal socket plug 3 is larger than the inner diameter of the internal socket plug 3, so as to form a limiting surface 5 at the bottom of the external plug interface 2. After installation, along the axial direction of the tube body 1, the limiting surface 5 abuts against the end surface of the external connection component, so that the external connection component can be assembled quickly and accurately through the limiting surface 5, thereby improving the assembly efficiency.

[0034] A thrust surface 6 with a conical structure is also provided in the external plug-in interface 2, one end of the thrust surface 6 is connected to the limit surface 5, and the other end is connected to the cylindrical surface of the external plug-in interface 2;

[0035] A limiting ring 8 is also provided on the outer circumferential surface of the pipe body 1, and the limiting ring 8 is integrally connected with the pipe body 1 to improve the connection strength. After being connected with the connecting pipe, the end face of the limiting ring 8 and the end face of the connecting pipe abut against each other, and the outer diameter of the limiting ring 8 is the same as the outer diameter of the connecting pipe to ensure the flatness of the connected pipe;

[0036] The electric fusion pipe joint also includes a hot melt module, which includes an electric heating wire 4. The electric heating wire 4 is arranged in a spiral structure. The electric heating wire 4 is embedded in the inner socket plug 3, and the electric heating wire 4 completely covers the inner socket plug 3, or only the end portion of the inner socket plug 3 is not covered.

[0037] When in use, the entire joint and the connecting pipe are placed in an AC electric field, which will be heated by eddy currents, thereby achieving hot-melt connection, thereby increasing the connection strength as much as possible and preventing water seepage from the joint;

[0038] At the same time, an electric heating wire 4 is arranged in the limit groove, so that the edge sealing operation of the connecting pipe end can be realized simultaneously, thereby improving the edge sealing quality.

[0039] Compared with the prior art, the hot melt assembly can realize the rapid hot melt connection of the plug-in area, which is beneficial to improve the connection efficiency of the pipeline; at the same time, compared with the traditional adhesive bonding method, the hot melt connection realizes the melting and mixing of the pipeline and the connecting device materials, and improves the connection strength between the connecting device and the connected pipeline as much as possible, which is beneficial to prevent the occurrence of water seepage in the joint;

[0040] Secondly, in the technical solution described in the present application, the internal joint is inserted into the pipe to be connected, so the end portion of the pipe to be connected, which is most prone to leakage and delamination, will be directly opposite the pipe joint, that is, the end of the connected pipe is separated from the water flow through the above-mentioned connection method, thereby improving the edge sealing effect, blocking the contact between the water flow and the end area from the source, thereby avoiding fluid infiltration, delamination and the like in the pipe to be connected, and extending the service life of the pipe to be connected.

[0041] The above are only preferred embodiments of the present application, and are not intended to limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
