Specifically, electric melting pipe fittings refer to can melt a kind of plastic tube for reaching connection by temperature caused by electric current Material accessory.The matrix of electric melting pipe fittings is PE material, and the PE pipe-line system that electric melting pipe fittings and PE pipe form preferably solves conventional tube The corrosion and joint leaks problem in road.
It is connected using electric melting pipe fittings, it is integrated with tubing to realize connector, can have to movement underground and end load Effect is resisted.After PE pipe-line system is using welding process connection, connector leakage will not occur for the resistance to end load of connector.Meanwhile PE is answered Power relaxation property effectively can consume stress by deformation, therefore, in joint and knee, do not need in most cases into The anchoring of row somewhat expensive.But existing electric melting pipe fittings are easy to damaged electric leakage in power connector end setting position protrusion, separately Outside, divide the uniformly distributed electrothermal conductor in pipe material inner wall, so that its mechanical property of pipe laying is easier stress, temperature and time Etc. factors influence, there is the phenomenon that stress relaxation, in addition, the creep and relaxation deformation of long pipeline can reduce its performance.
Utility model content
The purpose of the utility model is to provide the embedding conductive filament electric heating melting plastic pipe fittings of wall.
The purpose of this utility model will be realized by following technical measures: connect electricity including pipe fitting, heater strip, activity waterproof Seat, electrical terminals and caulking groove;There are recessed caulking groove, activity waterproof power connection seat at least internal periphery shape on pipe fitting outer wall by pipe fitting Shape is identical as caulking groove cavity shape.
Especially, inside pipe wall uniform screw thread winding insertion heater strip.
Especially, the both ends of heater strip are separately mounted to pipe fitting both ends.
Especially, the both ends of heater strip are separately mounted to pipe fitting one end.
Especially, there is block key in inwardly annular outstanding in the middle part of pipe fitting inner wall, and the internal diameter of interior block key is greater than tubing Internal diameter but be less than pipe fitting internal diameter.
Especially, electric heating plastic layer is embedded in pipe fitting inner wall.
The advantages of the utility model and effect: pipe fitting inner wall structure is improved, by making pipe fitting inner wall by external electric heating Hot melt inside contracts connection tubing, and is bonded as one after further realizing cooling, junction fastening, waterproof, and melting adhered process is equal Even, moreover, plugging position is easy to remedy construction, construction also safe ready, corrosion-resistant, service life are replaced in subsequent tubing maintenance Long, joint does not leak, and reduces the deformation that long pipeline is generated by creep and relaxation, improves its performance.
Detailed description of the invention

Fig. 2 is 2 schematic diagram of application structure of the utility model embodiment.
Appended drawing reference includes:
Tubing 1, pipe fitting 2, heater strip 3, interior block key 4, activity waterproof power connection seat 5, electrical terminals 6, caulking groove 7, electric heating plastic cement Layer 8.
Specific embodiment
The utility model principle is that the principle of electric-heating in electric melting pipe fittings is respectively two classes, and one is common to pass through Exposed receiving electrode accesses the heating wire conductive exothermal being embedded in pipe fitting inner wall, and another kind is by external equipment electromagnetic induction pair The metal mesh heating being embedded in pipe fitting inner wall and further hot melt pipe fitting inner wall, wherein external equipment is to adopt similar to electromagnetic oven With magnetic field induction vortex principle, it works as magnetic field to generate countless magnetic confining field power by loop coil using the electric current of high frequency The magnetic line of force generates induced current by metal mesh magnetizer, generates countless small vortex, its secondary load is made voluntarily to generate heat at a high speed. The electromagnetic wave that external equipment generates when working, is absorbed by the shielded layer of its coil and metal mesh completely.
Research finds the metal mesh in pipe fitting inner wall after electric heating, it some times happens that loosely organized parsing cracking shows As locating outside the fracture toughness directly reduced and intensity, the sealing effect of abutting edge is also affected.
The embedding conductive filament electric heating melting plastic pipe fitting of the utility model wall include: pipe fitting 2, heater strip 3, activity waterproof power connection seat 5, Electrical terminals 6 and caulking groove 7.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Embodiment 1: as shown in Fig. 1,2 inner wall of pipe fitting is embedded in heater strip 3, and 2 outer wall of pipe fitting is hinged with activity waterproof and connects electricity Seat 5 is equipped with electrical terminals 6 on the inside of activity waterproof power connection seat 5, and electrical terminals 6 are connect with heater strip 3, moreover, in activity waterproof There is recessed caulking groove 7 on 2 outer wall of pipe fitting on the side of power connection seat 5, in at least internal periphery shape of activity waterproof power connection seat 5 and caulking groove 7 Chamber shape is identical.
