Background technology
It is that a kind of conventional pipe connects mode instantly that tempreature bulb, which connects, when tempreature bulb connects, using by the pipeline of required connection
Prior simple concatenation, is then heated so that the pipe joint being made up of hot melt material softens, and stitching portion is also mutually merged,
Finally cool down and formed the connected mode of integral type, this connected mode other common modes such as is spirally connected or welded more than traditional
For secure rigid, and it is difficult to leak out or disengages, but the mode that tempreature bulb connects also often occurs that indivedual junction gaps are larger, and even
Bubble more situation when connecing, more seriously in hot melt, insides of pipes softens and deformation is easily caused the pipeline after connection
Uneven distribution.
In order to solve the problem of prior art is present, people carry out long-term exploration, it is proposed that miscellaneous solution party
Case.For example, Chinese patent literature discloses a kind of style plastic pipe connector provided with heating ring and preparation method thereof, [application number：
201510740546.5], including conduit coupling body, it is recessed that the conduit coupling body two ends are respectively equipped with tubing socket joint
METAL HEATING PROCESS ring is embedded with groove, the conduit coupling body of the socket joint groove outer rim.It is of the present invention to make inner-walls of duct
Plastic layer and pipeline outer wall plastic layer simultaneously with conduit coupling welding.
Scheme above is the electromagnetic induction melt process generally used in the prior art, by pipe joint and body phase interfix
After connecing, by applying electromagnetic field so that its internal electromagnetic induction METAL HEATING PROCESS from outside, and cause pipe joint and body heat
Melt and combine together, then a kind of situation easily occurs in this method, the inner side of socket joint groove can be become by heat under hot melt state
Shape, so as to cause to connect defective tightness, easily produces gap or hole, and this deformation is irreversible after successful connection and cooling
, ultimately resulting in its passage not enough to smooth out, or even with projection or groove.
Utility model content
The purpose of this utility model is in view of the above-mentioned problems, providing one kind pipeline to be helped to be unlikely to deform and connect in hot melt
Connect the more close internal expanding type movable sleeve connect suitable for tempreature bulb.
To reach above-mentioned purpose, the utility model employs following technical proposal：This is applied to the internal expanding type that tempreature bulb connects
Movable sleeve includes tubular body, and described body runs through breach so that set physical efficiency provided with one through body two ends
Realize and radially scale, be distributed in one end of body provided with some in circumferencial direction and respectively along the bar-shaped trough of body Longitudinal extending,
Curved elastic strip body is formed between adjacent bar-shaped trough.The body can be placed on the inside of hot-melting pipe joint, connected in hot melt
When connecing, inwall can be abutted against, makes pipeline connection more close, and avoids insides of pipes softening transform, and can be extruded
Unnecessary bubble.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, under described bar-shaped trough is extended in body
Portion.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, described body by during electromagnetic induction by that can be sent out
The metal material of heat is made.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, described body is made of stainless steel.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, described bar-shaped trough is uniformly distributed in circumferencial direction
And the width of each bar-shaped trough is equal.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, the described one end of body provided with bar-shaped trough is in set
Towards the outer end of inner ring when body inserts in the inner ring of hot-melting pipe joint.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, described body inserts in hot-melting pipe joint in body
Inner ring when be in radial contraction state.
The above-mentioned internal expanding type movable sleeve connect suitable for tempreature bulb, described body inserts in hot-melting pipe joint in body
Inner ring when described in be closed through breach and body outer wall and inner ring inwall tight fit.
Compared with prior art, this advantage for being applied to the internal expanding type movable sleeve that tempreature bulb connects is：It is completely embedded, covers
Body can apply the power that extend out from the inner side of inner ring, so that it is more close with body waiting, it is to avoid crack or leak
Produce；Inner ring is unlikely to deform, and body abuts against the inner side of inner ring, and because elastic reaction, outside applying to the inwall of inner ring
The power of expansion, therefore in reflow process, deformation on the inside of inner ring can be prevented and rough phenomenon is produced；Hot-melt adhesive paste efficiency
Height, body is also the metal material of electromagnetic induction heating in itself, can be heated pipeline from inner side.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model is provided.
Fig. 2 is the schematic diagram that body is put into inner ring.
In figure, body 1, breach 2, bar-shaped trough 3, elastic strip body 4, hot-melting pipe joint 5, inner ring 6.
Embodiment
