Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the present invention.
A kind of attachment structure applied to spiral corrugated stainless steel tubing as shown in Figures 1 to 4, including fastening newel
Body 1 and outer nut 2, center column 1 one end is fastened in actual production can be fixedly connected point by welding, integrally formed mode
Hydrophone or other water-outlet bodies, fastening center column 1 are connected through a screw thread outer nut 2, and the fastening other end of center column 1 is machined with
External screw thread, the inwall processing of outer nut 2 have internal thread, and the effect of fastening is realized by the cooperation of external screw thread and internal thread.In fastening
It is in boss structure 3 in stem body 1, fastening center column 1 is radially sequentially provided with through hole 4, sealing neck 5, ferrule 6 from the inside to the outside
And pad 7, sealing neck 5 top are provided with plain cushion 7, sealing neck 5 inwall is provided with the ripple to match with spiral corrugated stainless steel tubing
Line, spiral corrugated stainless steel tubing are screwed in sealing neck 5, and the sealing inwall of neck 5 is brought into close contact energy with spiral corrugated stainless steel tubing
Effectively prevent liquid from going out from the slot leakage between the sealing inwall of neck 5 and spiral corrugated stainless steel tubing.Plain cushion 8 and boss knot
The inwall of structure 3 fits, and serves the effect of sealing, prevents slot leakage of the liquid between plain cushion 8 and the inwall of boss structure 3
Go out.Pad 7 is bonded plain cushion 8, and ferrule 6 is bonded pad 7, sealing neck 5.It is the tight of achievable outer nut 2 not need professional tool
Acted on Gu producing one when outer nut 2 is fastened on fastening center column 1 and pushing power on pad 7, pad 7 is under outer nut 2
Pressure is decomposed into the lower pressure to plain cushion 8 and the tightening force to ferrule 6 so that the top of plain cushion 8 is brought into close contact boss structure 3
Inwall, and tightening force allows the sealing inwall of neck 5 to be more brought into close contact with spiral corrugated stainless steel tubing, strengthens sealing neck 5 and spiral
The sealing of formula corrugated stainless steel tubing.
Pad 7 is two panels, and the central bore of pad 7 is provided with chamfering 9, and chamfering 9 is bonded the both ends of ferrule 6 respectively, chamfering 9
Strengthen the effect of the tightening force of ferrule 6 equivalent to hard point is provided in inclined-plane.It is 20mm to seal the length of neck 5, and sealing neck 5 is
Quality of rubber materials is made, and elastomeric material plays better seal effect.Ferrule 6 is C-shaped, and the inwall of ferrule 6 is provided with projection 10, C
The deformation degree of shape ferrule 6 is big, and inwall is provided with projection 10 and strengthens stress point.Under tightening force effect so that sealing neck 5 and spiral shell
Rotating corrugated stainless steel tubing is more brought into close contact, and through hole 4 is T-shaped, and the top end diameter of through hole 4 is equal to the straight of spiral corrugated stainless steel tubing
Footpath, the bottom diameter of through hole 4 are more than the central bore diameter of outer nut 2, and the outer wall of outer nut 2 is in hexagon, and the central bore of outer nut 2 is straight
Footpath is more than the diameter of spiral corrugated stainless steel tubing, because the top end diameter of through hole 4 is equal to the diameter of spiral corrugated stainless steel tubing,
The hydraulic pressure for entering spiral corrugated stainless steel tubing from water knockout drum keeps constant, the control of hydraulic pressure when being easy to work；Moreover the bottom of through hole 4
End diameter is more than the central bore diameter of outer nut 2, can have gap between the bottom of through hole 4 and the central bore of outer nut 2, spirally
Corrugated stainless steel tubing can be put into the bottom of through hole 4 in the lump after being inserted in ferrule 6, pad 7, serve fixed effect.
The operation principle of the present embodiment is as follows：
1) first by spiral corrugated stainless steel tubing screw in sealing neck 5 in, until spiral corrugated stainless steel tubing port away from
Seal at the top 1mm of neck 5；
2) then it is inserted in pad 7 toward spiral corrugated stainless steel tubing and is bonded plain cushion 8, then is inserted in ferrule 6 and is bonded pad 7,
The last pad 7 that is inserted in again is bonded ferrule 6, and whole process ensures the face of the chamfering 9 fitting ferrule 6 of pad 7, tentatively completion group
It is fit；
3) the assembly insertion fastening central body 1 completed will be assembled, spiral corrugated stainless steel tubing is inserted in outer nut 2 simultaneously
Screw, with the precession in fastening central body 1 of outer nut 2, ferrule 6 is gradually tightened up, closed up by the chamfering 9 of two pads.
Now ferrule 6 will seal neck 5 and further push, tighten up, and suppressing action makes its strength enrich the fitting inwall of boss structure 3；Receive
Tight effect makes its strength enrich into the trench of helical corrugation, makes shipwreck to reveal, reaches the effect of sealing.
In summary, using a kind of attachment structure applied to spiral corrugated stainless steel tubing provided by the present invention, no
It is the connection that spiral corrugated stainless steel tubing and water-outlet body can be achieved by any professional tool, connection sealing is strong, operation side
Just.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
God any modification, equivalent substitution and improvements done etc., should be included within the scope of protection of the invention with principle.
