Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, to make those skilled in the art's reference
Description word can be implemented according to this.
As shown in Figure 1, 2, core pipe 1 is the cylinder with accommodating cavity, preferably metal material；It is situated between
Matter is by housing cavity conveying, and metallic cylinder two ends are the straight tubes that outside dimension is different, by a light between straight tube
Sliding overbank cylinder connects.The excircle of metallic cylinder external diameter small end is provided with the first teeth portion, preferably
For annular teeth portion；The excircle of the bigger end of metallic cylinder external diameter is provided with screw thread, and its excircle can overlap
If fixed body 2 and shaping cover 4.
Outer sleeve 3 is circular sleeve, preferably metal material；A sleeve part is straight tube, its inner periphery
It is provided with the second teeth portion, is preferably annular teeth portion；Sleeve another part is smooth oblique cylinder, oblique cylinder
Front inner diameter matches with the external diameter of 1 oblique one end of core pipe；Tiltedly cylinder front end and 1 oblique one end of core pipe are fixed
Connect, preferred as one, use welding manner to connect.Outer sleeve 3 and core pipe 1 are composed of a fixed connection
Joint body, the second teeth portion is the most corresponding with the first position, teeth portion；At the first teeth portion and the second tooth
Tooth has gap between portion, has the effect of withholding, and as a kind of preferred, the first teeth portion and second
The teeth in teeth portion are unidirectional teeth, and unidirectional teeth can more preferably hold on flow string；First teeth portion and
Gap between second teeth portion is for inserting the portion inner layer of flow string or flow string, and the first tooth
Tooth portion and the second teeth portion have clamping and hold the effect that flow string does not exits.
As it is shown on figure 3, fixed body 2 is circle shape part, preferably metal material；Circle ring inner surface sets
Having screw thread, its internal diameter size matches with the external diameter of the core pipe 1 bigger end of external diameter, can be set on core pipe 1；
There are on torus several through holes, preferred as one, torus has 6 through holes, through hole is straight
Footpath specification is mated with the steel wire in flow string, and steel wire is passed by through hole；Torus outer rim has several
Groove, preferably 3 grooves；Groove size matches with cable, and steel wire is passed by groove；3
Groove is for angularly to lay；Preferred, between adjacent groove and through hole, through hole and through hole etc. as one
Angle is arranged.
As shown in Figure 4,5, shaping cover 4 is the circular sleeve with accommodating cavity；It is preferably metal material；
On the end face of shaping cover 4, around central through hole there is several through holes, preferably 3 through holes, 3
Individual through hole is for angularly to lay；Through-hole diameter specification matches with the cable of flow string, the cable of flow string
Passed by through hole；Central through hole size matches with the external diameter of the core pipe 1 bigger end of external diameter, its inner surface
It is provided with screw thread；Shaping cover 4 other end is hatch frame, opening size and sealing flange 5 external diameter
Size is mated.
As shown in Figure 6, sealing flange 5 circle shape part, preferably metal material；Open on torus
Having central through hole, clear size of opening to match with flow string, flow string is passed by central through hole；Torus
Excircle is provided with screw thread, can be threaded into qualitative set 4 opening.
As it is shown in fig. 7, the present invention uses withholds connection, fixation with steel wire connection and resin-cast sizing three kinds
The mode that method combines connects flow string, and it is embodied as step and is:
A, being inserted in outer sleeve 3 of core pipe 1, the oblique cylinder front end of outer sleeve 3 and 1 oblique one end of core pipe
Connect；After being welded to connect place, core pipe 1 and outer sleeve 3 integral connector body；Flow string 6 front end
Steel wire 7 and the cable 8 at position are exposed outside, flow string main body are inserted in the gap of joint body,
Unidirectional teeth portion in first teeth portion and the second teeth portion buckles the inside and outside wall of flow string, can play clamping
The effect do not exited with holding flow string.
B, fixed body 2 are set on the core pipe end excircle of joint body and are threaded into；Three steel
Silk 7 is through three non-conterminous through holes on fixed body 2, and steel wire 7 reversely leads to from the other three more afterwards
Hole passes fixing；Three of the cables 8 passes from three grooves of fixed body 2.
C, again shaping cover 4 is set on the core pipe end excircle of joint body, leans on by being threaded into
The position of nearly fixed body 2, is limited to fixed body 2 between shaping cover 4 and joint body；By three electricity
The cable 8 three through holes from shaping cover 4 pass connector exterior；Afterwards sealing flange 5 is passed through spiral shell
The opening of stricture of vagina precession shaping cover 4；Finally molten state epoxy resin is poured into the accommodating sky of shaping cover 4
Intracavity, molten resin has preferable mobility so that it is fill each space to cavity；At 2 days
Health preserving solidification process in, epoxy resin 9 be cross-linked with each other and with jointing adhesion be solidified into one.
Of the present invention provide the benefit that joint use withhold connections, fixation with steel wire connected mode combination
Mode, is greatly improved pressure-bearing and the bearing capacity of jointing, further, it is also possible to resin-cast is even
Connect, after using above 3 kinds of connected modes, its anti-load intensity reached that tubing conducts oneself with dignity 2.5～3 times with
On, better meet the requirement that flow string uses；And this joint is generally applicable to nonmetal continuous oil recovery
Pipe, is particularly suited for the flow string that cable, steel wire and pipeline are integrated.
Although embodiment of the present invention are disclosed as above, but it is not restricted to description and embodiment party
Listed utilization in formula, it can be applied to various applicable the field of the invention completely, for being familiar with ability
For the personnel in territory, be easily achieved other amendment, therefore without departing substantially from claim and etc. homotype
Enclosing under limited general concept, the present invention is not limited to specific details and shown here as the figure with description
Example.
