Abstract

The utility model discloses a plastic pipe electromagnetic melting connection structure which belongs to a pipeline connecting structure, the exiting melting structure is not applicable to melt a pipeline with large diameter, and remediation can not be carried out when leakage occurs after melting. In the connection structure, a connecting end of a pipe fitting is provided with an outer ring wall, the inner side of the outer ring wall is provided with a receiving port, a plastic pipe is inserted into the receiving port, and a melting ring which is melted with the outer ring wall and the plastic pipe is arranged between the outer ring wall and the plastic pipe. As for the connection structure, the plastic pipe is firstly inserted into the receiving port of the plastic pipe fitting when the connection is carried out, and then electromagnetic induction heating is conducted on the melting ring at the inserting part so as to realize the melting so as to lead to easily implement; and if the melting quality is poor to cause water leakage or water seepage, the inserting part can be heated again for the remediation.

Description

The plastic tube electromagnetism melts linkage structure

Technical field

The utility model belongs to pipe connecting structure, specifically is that a kind of heat that produces by electromagnetic field is realized the pipe connecting structure that plastic tube is connected with plastic pipe.

Background technique

The welding of existing plastic tube and plastic pipe, mostly be to realize connecting with again plastic tube being inserted plastic pipe after plastic pipe and the plastic tube heat fused respectively by the heating die sleeve, this welding process since when pegging graft plastics be molten state, easily knurl is melted in off normal and generation, therefore be applicable to the welding of small-bore pipeline more, and be unsuitable for welding, and can't remedy when seepage occurring after the welding large diameter pipeline.

Summary of the invention

The technical assignment of the technical problems to be solved in the utility model and proposition be overcome existing by the heating die sleeve respectively with again plastic tube being inserted the defective that plastic pipe being unsuitable for due to realizing being connected can't be remedied when seepage occurring after the welding of large diameter pipeline and the welding after plastic pipe and the plastic tube heat fused, provide a kind of plastic tube electromagnetism to melt linkage structure.

Realize the purpose of this utility model for this reason, the utility model adopts following technical proposals: the plastic tube electromagnetism melts linkage structure, comprise plastic tube and plastic pipe, described plastic pipe has the connecting end of at least two connections, and at least one connecting end is shaped on external annulus and forms birdsmouth in described external annulus inboard, described plastic tube inserts in the described birdsmouth, it is characterized in that: be equipped with the welded ring with the two welding between described external annulus and the plastic tube.

As the optimization technique measure, described welded ring with described external annulus built in.

As the optimization technique measure, described welded ring and described external annulus split configuration.At this moment, the inner of described welded ring has the flanging that bends inwards.

As the optimization technique measure, offer through hole on the peripheral wall of described welded ring.

As the optimization technique measure, the surface attachment of described welded ring has heat-fusing glue layer.

The beneficial effects of the utility model are: produce the welding that heat is realized plastic tube and external annulus by the welded ring induction field that is arranged between plastic tube and the external annulus.This linkage structure is inserted plastic tube in the birdsmouth of plastic pipe earlier when implementing to connect, and again the welded ring of plugging position is implemented electromagnetic induction heating and realizes welding, and is easy to implement; Do not need plastic pipe, pipe are carried out special structural design; Be applicable to the welding of the plastic tube and the plastic pipe of all size; Cause leaking if the welding quality is not good or when seeping water, can be once more to plugging position heating enforcing remedies.

Embodiment

Below in conjunction with Figure of description the utility model is described further.

Plastic tube electromagnetism of the present utility model melts linkage structure, as shown in Figure 1, it comprises plastic tube 1 and plastic pipe 2, plastic pipe 2(is referring to Fig. 2) connecting end 21(with at least two connections is illustrated as two logical plastic pipes, can be the threeway plastic pipe during concrete enforcement, four-way plastic pipe etc.), and two connecting ends that at least one connecting end is shaped on external annulus 22(diagram two logical plastic pipes all are shaped on) and at the external annulus 22 inboard birdsmouths 23 that form, plastic tube 1 inserts in the birdsmouth 23, is equipped with the welded ring 3 with the two welding between external annulus 22 and the plastic tube 1.

When concrete enforcement connects, earlier plastic tube 1 is inserted in the birdsmouth 23 of plastic pipe as shown in Figure 1, and welded ring 3 placed between external annulus 22 and the plastic tube 1, from the outside of plugging position the welded ring 3 of plugging position is applied magnetic field with electromagnetic induction heater 4 afterwards and make welded ring produce heat plastic tube 1, external annulus 22 fusings are fused together, the welding of plastic tube 1 and plastic pipe 2 is realized in the cooling back.

Owing to be earlier plastic tube 1 to be inserted in the birdsmouth 23 of plastic pipe when implementing this linkage structure, again the welded ring 3 of plugging position is implemented induction heating and realize welding, easy to implement, especially be beneficial to some occasions that are unfavorable for the application of force in high-altitude, narrow space etc. and implement; Simultaneously, do not need plastic pipe, pipe are done special structural change,, can also omit the structure that is used for exhaust, holds molten knurl, be easy to make with respect to the method for pegging graft behind the hot melt; Be applicable to the welding of the plastic tube and the plastic pipe of all size; Cause seepage if the welding quality is not good, can will heat enforcing remedies to plugging position once more after the media discharge of inside.

As further improving and replenishing to technique scheme, the utility model also comprises following additional technical characteristics, though Fig. 1 has comprised the major part in following all additional technical features, it is preferred embodiment of the present utility model, but the utility model is not limited to this situation, according to specifically acting on they is selected for use on the described technological scheme of epimere when implementing the utility model.

For fear of the loss of welded ring, welded ring with external annulus built in.

Also can be with welded ring and external annulus split configuration, this moment, the inner with welded ring had the flanging (referring to Fig. 1) that bends inwards, so that rely on the inner of plastic tube when pegging graft welded ring was pushed birdsmouth.Location when the flanging that corresponding external annulus can certainly be set in the outer end of welded ring is realized pegging graft.

Offer through hole on the peripheral wall of welded ring, the plastically welding that can make welded ring both sides fusings strengthens heat seal strength together.

Surface attachment at welded ring has heat-fusing glue layer, in order to strengthen heat seal strength.
