Specific embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Embodiment one
As shown in figure 1, a kind of electromagnetism hot-melting pipe joint, extends out circle 7, institute including the body 2 with water through structure and elasticity
The body 2 stated is made up of hot melt material, and body 2 has at least one birdsmouth 3, is provided with the inner and this in described birdsmouth 3
The inner ring 4 that body 2 is connected and is coaxially disposed with birdsmouth 3, forms annular between described 4 outer wall of 3 inwall of birdsmouth and inner ring
Groove 5 is in the charge of, described groove 5 of being in the charge of is provided with least one steam vent 13 in hot melt for aerofluxuss.Described steam vent 13
Can discharge in connection, the gas in the gap of junction affects overall structure so as to avoid forming bubble after the cooling period
Intensity.Heating ring 6 is provided with described body 2, described heating ring 6 is by the metal material system that can be generated heat when being subject to electromagnetic induction
Into described elasticity extends out in being fixed on inner ring 4 with enclosing 7 radial contraction or radial contraction ground detachable interposing and is connected in inner ring 4.Tool
Body process：After body waiting 1 and body 2 are mutually inserted, electromagnetic generator can be applied in the periphery of body 2, and to this
Discharge electromagnetic field inside body 2, and the self attributes of heating ring 6, start heating in the presence of electromagnetic field, discharge substantial amounts of heat
Amount, and body 2 and body waiting 1 are heated, therefore the gap of the junction of body 2 and the hot melt of body waiting 1 is gradually filled out
Fill, last junction is combined together.And in this course, inner ring 4 it is easy because hot melt deformation, so as to cause its inwall easy
It is uneven, uneven distribution, so as to affect structural strength, inner ring 4 even in hot melt may direct part come off, so as to cannot
Mutually merge with the inwall of body waiting 1, therefore as Figure 1-3, wear in inner ring 4 it is flexible extend out circle 7, work as heating ring
6 are subject to electromagnetic induction adstante febre make to insert in the body waiting 1 being in the charge of in groove 5 and heat with body 2 to be connected and be connected in hot melt
Elasticity described in journey extends out the inner ring 4 under 7 pairs of heating statuses of circle and carries out radially extending out.Because elasticity extends out the presence of circle 7, begin
In applying to extend out to the inwall of inner ring 4 eventually, when particularly under hot melt state, can cause in inner ring 4 and body waiting 1
It is brought into close contact between wall, so as in hot melt, it is to avoid crack and leak occur, and inner ring 4 can be avoided to deform and occur
It is uneven, it is internal upon connection more to smooth out.
Further, elasticity extend out circle 7 be cylindrical in shape and side be provided with through elasticity extend out circle 7 two ends side breach 8.Should
Elasticity extends out the principle of circle 7 and is that the side breach 8, and due to the elasticity that itself has by oneself, the elasticity extends out circle 7 from the inside of inner ring 4
When taking-up is freely placed, overall meeting spread apart, and when placing it in 4 inner side of inner ring, will apply what is extended out inner ring 4 is thought
Power, so that inner ring 4 presses close to body waiting 1, and inner side is unlikely to deform.
Preferably, elasticity extends out the outer end that the outer end that circle 7 is extended out when elasticity and inner ring 4 are provided between circle 7 and inner ring 4
Elasticity can be prevented when flushing to extend out the location structure 9 that circle 7 continues to be moved axially inward relative to inner ring 4.Location structure 9 includes setting
The Sealing shield ring 10 and the stop surface 11 located at 4 outer end inner wall of inner ring, described Sealing shield ring 10 and backstop of 7 outer ends of circle are extended out in elasticity
Face 11 mutually coincide.Sealing shield ring 10 has the little enlarging face of outer imperial palace, described stop surface 11 taper surface little in outer imperial palace, institute
The enlarging face stated mutually is coincide with stop surface 11.Under the pressure of stop surface 11 for the obstruction of Sealing shield ring 10, elasticity extends out circle 7 just not to be had
Slide further in inner ring 4, and be to maintain the elastic circle 7 that extends out and be mutually flush with the port of inner ring 4.And in practice, can
So that elasticity extends out the depth of the depth more than or equal to heating ring 6 of circle 7, then 6 adstante febre of heating ring is made in electromagnetic field, heat state
Part body 2 and body waiting 1 can mutually more close connection.
Further, the metal material that can be generated heat when elasticity extends out circle 7 by by electromagnetic induction is made, and described bullet
Property extend out circle and 7 be made up of stainless steel material.So elasticity extends out circle 7 can not only make body 2 and body waiting 1 connect more tight
It is close, it is also possible to heating synchronous with 6 combination of inner and outside of heating ring, further improve the efficiency of hot-melt adhesive paste.Elasticity extends out circle 7 by stainless
Steel material is made and is fixedly arranged on after hot melt and inserts on the inner ring 4 that is integrated of hot melt of body waiting 1 being in the charge of in groove 5.Simultaneously
It is difficult to get rusty, long service life.
As shown in figure 4, heating ring 6 is cylindrical in shape, some hot-melt adhesive paste holes 12, described heating are provided with 6 sidepiece of heating ring
6 build-in of ring in birdsmouth 3 and heating ring 6 internal diameter not less than the external diameter for being in the charge of groove 5.If the not no hot-melt adhesive paste hole 12
Exist, then, after hot-melt adhesive paste, entirety is in that plastics, metal, three layers of plastics are clearly layered from inside to outside, therefore inside and outside
Plastics are isolated by heating ring 6, and stability is bound to be short of, and if being provided with the hot-melt adhesive paste hole 12, inside and outside
Plastics be connected with each other by hot-melt adhesive paste hole 12, and heating ring 6 is inlayed wherein, the structure of integral type
It is more stable, and heating ring 6 can also greatly improve its structural strength.The outer end of described inner ring 4 is extended to outside birdsmouth 3.
Embodiment two
The present embodiment is similar to the structural principle of embodiment one, and unique difference is：As shown in figure 5, heating ring 6 is wrapped
Inner barrel and outer cylinder body are included, in 4 outer wall of inner ring, described outer cylinder body build-in is in birdsmouth inwall, institute for described inner barrel build-in
It is connected in the annular solid for being in the charge of 5 bottom of groove by build-in between the inner barrel stated and outer cylinder body, and inner barrel, outer cylinder body and annular
Hot-melt adhesive paste hole 12 is respectively equipped with body.The principle in hot-melt adhesive paste hole 12 is identical with embodiment one, and inner barrel and outer cylinder body can
To improve heating efficiency, adapter body 1 is treated from inside and outside both direction and body 2 is heated, accelerate its hot melt, and connect
After the completion of connecing, by inner barrel and outer cylinder body presence and its structural strength is higher.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
Category those skilled in the art can make various modifications or supplement or using similar to described specific embodiment
Mode substitute, but without departing from it is of the present utility model spirit or surmount scope defined in appended claims.
Although more having used body waiting 1, body 2 herein, birdsmouth 3, inner ring 4, being in the charge of groove 5, heating ring 6, bullet
Property extends out the terms such as circle 7, side breach 8, location structure 9, Sealing shield ring 10, stop surface 11, hot-melt adhesive paste hole 12, steam vent 13, but
It is not precluded from the probability using other terms.It is new just for the sake of more easily describing and explaining this practicality using these terms
The essence of type；It is all contrary with this utility model spirit to be construed as any additional restriction.
