[0003] The existing connection method has the following disadvantages: the operator needs to apply glue manually, which is troublesome and requires high experience of the operator. If the glue is not applied evenly, it is easy to cause the glue at the connection to be loose, thus causing leakage at the connection of the pipe. Summary of the invention

Multiple hot melt adhesive rings are arranged on the inside of the interface pipe, which effectively improves the connection effect between the interface pipe and the connected pipe, and greatly reduces the risk of leakage at the interface position. The axial positioning mechanism plays an axial positioning role on the connected pipe. In the process of hot melt adhesive melting and bonding, the axial positioning mechanism is used to prevent axial movement between the connected pipe and the interface pipe. The utility model is easy to operate, has low requirements on the experience level of operators, and has good connection effect.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.
[0022] like Figures 1 to 6 As shown, a pipe electromagnetic induction electric fusion connection structure includes an interface pipe 1, a connected pipe 2, and a high-frequency induction coil 10. The interface pipe 1 and the connected pipe 2 are made of PE or PVC. A plurality of annular grooves are provided on the inner side of the interface pipe 1, and the annular grooves are arranged along the axial direction of the interface pipe 1. A metal induction ring 3 is provided in the annular groove. In this embodiment, the metal induction ring 3 is made of brass. A hot melt adhesive ring 4 is provided on the inner side of the metal induction ring 3. The hot melt adhesive ring 4 is in a circular ring shape and is embedded in the annular groove, and the material of the hot melt adhesive ring 4 is hot melt adhesive. The high-frequency induction coil 10 is used to perform induction heating on the metal induction ring 3. When the high-frequency induction coil 10 performs induction heating on the metal induction ring 3, the high-frequency induction coil 10 is sleeved on the outer side of the interface pipe 1.
[0023] The outer side of the connected pipe 2 is provided with a sol contact ring surface corresponding to the hot melt adhesive ring 4, and the sol contact ring surface is provided with an embedded glue structure. In this embodiment, the embedded glue structure is an external threaded body 9 provided on the sol contact ring surface.
[0024] An axial positioning mechanism is provided between the connected pipe 2 and the interface pipe 1. The axial positioning mechanism includes an avoidance groove 5 provided on the inner side of the interface pipe 1, and an elastic sheet 6 provided in the avoidance groove 5. The elastic sheet 6 is made of spring steel, one end of the elastic sheet 6 is fixed on the side arm of the avoidance groove 5, and the other end of the elastic sheet 6 is provided with a buckle body 7. An axial positioning ring groove 8 corresponding to the buckle body 7 is provided on the connected pipe 2. The axial positioning mechanism plays an axial positioning role on the connected pipe 2. When the connected pipe 2 is inserted into place, the buckle body 7 at the end of the elastic sheet 6 is snapped into the axial positioning ring groove 8 on the connected pipe 2.
[0025] When the utility model is used, the pipe end of the connected pipe 2 is first inserted into the interface pipe 1. After the connected pipe 2 is inserted in place, the sol contact ring surface on the outside of the connected pipe 2 corresponds to the hot melt adhesive ring 4 on the inside of the interface pipe 1. Then, the high-frequency induction coil 10 is sleeved on the position on the outside of the interface pipe 1 corresponding to the metal induction ring 3. After the high-frequency induction coil 10 is energized, the metal induction ring 3 is inductively heated. The metal induction ring 3 is heated and the hot melt adhesive ring 4 on the inside is melted. The melted hot melt adhesive is bonded to the outside of the connected pipe 2. After the heating is completed, the high-frequency induction coil 10 is removed. After the hot melt adhesive is cooled and solidified, the bonding between the interface pipe 1 and the connected pipe 2 is completed. The setting of the embedded glue structure can embed the melted hot melt adhesive into the embedded glue structure, thereby enhancing the bonding between the hot melt adhesive ring 4 and the connected pipe 2. Multiple hot melt adhesive rings 4 are arranged on the inside of the interface pipe 1, which effectively improves the connection effect between the interface pipe 1 and the connected pipe 2 and greatly reduces the risk of leakage at the interface position. The axial positioning mechanism plays an axial positioning role on the connected pipe 2. During the hot melt adhesive melting and bonding process, the axial positioning mechanism prevents axial movement between the connected pipe 2 and the interface pipe 1. The utility model is easy to operate, has low requirements on the operator's experience level, and has a good connection effect.
