Specific embodiment
It is of the invention to reach the technical means and efficacy that predetermined goal of the invention is taken further to illustrate, below in conjunction with
Attached drawing and preferred embodiment, to specific embodiment, structure, feature and its effect is proposed according to the present invention, detailed description is as follows.
Refer to Fig. 2, Fig. 3, the first embodiment of the present invention for connecting the electric melting pipe fittings of unlike material tubing, including
The plastics connecting pin 1 of the different materials of multiple tubuloses, the metalwork 2 being connected to multiple plastics connecting pins 1, the metalwork 2 are used for
It is connected to multiple plastics connecting pins 1, a kind of material in PE, PE-RT, PPR of plastics connecting pin 1.The metalwork 2 respectively with it is multiple
Plastics connecting pin 1 is tightly connected and is connected and fixed.
1 inner surface of plastics connecting pin is equipped with resistance wire 11.11 spacing difference of resistance wire keeps the temperature generated different, resistance wire
Temperature caused by 11 spacing is bigger is lower, and the smaller generated temperature of the spacing of resistance wire 11 is higher.The modeling of different materials
Expect the resistance wire 11 of the corresponding different spacing in connecting pin 1.The resistance wire 11 of multiple plastics connecting pins 1 is parallel with one another or mutual series winding.
11 both ends of resistance wire are connected with the electrode tip 12 that 1 outer peripheral surface of plastics connecting pin is arranged in.
Metalwork 2 is made of copper or stainless steel.Metalwork 2 has the tubulose buried section of the tubulose of embedment plastics connecting pin 1
21.Tubulose buried section 21 is for being promoted and the bonding strength of plastics connecting pin 1.21 outer peripheral surface of tubulose buried section and/or inner peripheral surface
Equipped with spaced apart bulge loop 211 and groove 212.The section of bulge loop 211 is gradually to increase backwards to 21 center width of tubulose buried section
What is added is trapezoidal.The section of bulge loop 211 is rectangular or square.
In process of production, the plastic raw materials of a variety of not same materials are fixed on 2 appearance of metalwork by quadric injection mould
Face, to be shaped to whole pipe fitting base, later by electric smelting wiring technique, in the embedding resistance wire 11 of pipe fitting embryo inner surface, most
The electric melting pipe fittings being fabricated to eventually can be connect with the tubing electric smelting of a variety of different materials.
The electric melting pipe fittings are bypass structure, and the quantity of plastics connecting pin 1 is two, and plastics connecting pin 1 can be by two kinds of materials
It is made.In use, two plastics connecting pins 1 of the electric melting pipe fittings first are connected respectively the tubing of different materials,
It is then welded to connect electrode tip 12, starts to weld, since the spacing of resistance wire 11 is different, suffered by two plastics connecting pins 1
The temperature arrived is different, to be suitable for connecting the tubing of different materials.
Refer to Fig. 4, in the second embodiment of the present invention, the tubulose buried section 21 of metalwork 2 plastics with two sides respectively
Connecting pin 1 is fixedly connected, and the plastics connecting pin 1 of side is not contacted with the plastics connecting pin 1 of the other side, and metalwork 2, which has, to be located at
Exposed connecting pin 22 between the plastics connecting pin 1 of side and the plastics connecting pin 1 of the other side.The inner wall of metalwork 2 and two sides
The inner wall of plastics connecting pin 1 be in same plane.The plastics connecting pin 1 of two sides is respectively provided with a pair of electrodes head 12.
In process of production, since metalwork 2 only has tubulose buried section 21 to be fixedly connected with plastics connecting pin 1, there are also naked
It is exposed outside to reveal connecting pin 22, therefore is capable of fixing the plastics connecting pin 1 of 2 two sides of simultaneous processing metalwork behind exposed connecting pin 22.
Compared to the electric melting pipe fittings that the plastics connecting pin 1 of first embodiment is coated on metalwork 2, embodiment improves the effects of processing
Rate.
In use, the plastics connecting pin 1 of two sides can individually be connect with tubing electric smelting, need to only control the work of welding
Time and power can correspond to the tubing of welding of different materials.Compared to the resistance wire 11 of the different spacing of first embodiment, this reality
It is higher to apply a welding precision.
Refer to Fig. 5, in the third embodiment of the present invention, which is three-port structure, the quantity of plastics connecting pin 1
It is three, plastics connecting pin 1 can be made of three kinds of materials.A pair of electrodes head 12 of plastics connecting pin 1 in same axis is logical
The electrical connection of resistance wire 11 is crossed, there is a pair of electrodes head 12 perpendicular to the plastics connecting pin 1 of axis.Compared to two of first embodiment
Plastics connecting pin 1, the present embodiment are applicable in increasingly complex pipeline connection.
Refer to Fig. 6, in the fourth embodiment of the present invention, which is four-way structure, the quantity of plastics connecting pin 1
It is four, plastics connecting pin 1 can be made of four kinds of materials.A pair of electrodes head 12 of plastics connecting pin 1 in same axis is logical
The electrical connection of resistance wire 11 is crossed, is electrically connected perpendicular to a pair of electrodes head 12 of the axis by resistance wire 11.Compared to first embodiment
Two plastics connecting pins 1, the present embodiment is applicable in increasingly complex pipeline connection.
In the present invention, 21 outer peripheral surface of tubulose buried section and/or inner peripheral surface are equipped with spaced apart bulge loop 211 and groove 212,
The bonding strength of metalwork 2 Yu plastics connecting pin 1 is improved by tubulose buried section 21.
In the present invention, pass through the plastics connecting pin 1 of multiple and different materials and the gold for being connected to multiple plastics connecting pins 1
Belong to part 2, the electric melting pipe fittings is made to have the effect of that the tubing electric smelting with a variety of different materials is connect.
More than, it is only presently preferred embodiments of the present invention, is not intended to limit the present invention in any form, although this
Invention has been disclosed in a preferred embodiment above, and however, it is not intended to limit the invention, any person skilled in the art,
It does not depart within the scope of technical solution of the present invention, when the technology contents using the disclosure above make a little change or are modified to equivalent
