Embodiment
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
A kind of linkage structure being applied to spiral corrugated stainless steel tubing as shown in Figures 1 to 4, comprise fastening center column 1 and outer nut 2, in actual production, fastening center column 1 one end is fixedly connected with water knockout drum or other water-outlet body by welding, integrated mode, fastening center column 1 is threaded connection outer nut 2, fastening center column 1 the other end is processed with outside thread, outer nut 2 inwall is processed with internal thread, realizes fastening effect by outside thread with coordinating of internal thread.In boss structure 3 in fastening center column 1, fastening center column 1 is radially provided with through hole 4, sealing neck 5, metal ferrules 6 and pad 7 from the inside to the outside successively, sealing neck 5 top is provided with plain cushion 7, sealing neck 5 inwall is provided with the ripple matched with spiral corrugated stainless steel tubing, spiral corrugated stainless steel tubing screws in sealing neck 5, and sealing neck 5 inwall and spiral corrugated stainless steel tubing fit tightly and can effectively prevent liquid from going out from the slot leakage sealed between neck 5 inwall and spiral corrugated stainless steel tubing.Plain cushion 8 and boss structure 3 inwall fit, and serve the effect of sealing, prevent liquid from going out from the slot leakage between plain cushion 8 and boss structure 3 inwall.Pad 7 is fitted plain cushion 8, and metal ferrules 6 is fitted pad 7, sealing neck 5.Do not need professional tool can realize the fastening of outer nut 2, producing a downforce when outer nut 2 is fastened on fastening center column 1 acts on pad 7, pad 7 is decomposed into outer nut 2 downforce the downforce of plain cushion 8 and the tightening force to metal ferrules 6, plain cushion 8 top is made to fit tightly boss structure 3 inwall, and tightening force allows sealing neck 5 inwall and spiral corrugated stainless steel tubing more fit tightly, the sealing of enhanced leaktightness neck 5 and spiral corrugated stainless steel tubing.
Pad 7 is two panels, and pad 7 central bore is provided with chamfering 9, and chamfering 9 is fitted the two ends of metal ferrules 6 respectively, and the inclined-plane of chamfering 9 is equivalent to provide hard point, the effect of the tightening force of reinforcement metal hoop 6.Sealing neck 5 length is 20mm, and sealing neck 5 is made for quality of rubber materials, and rubber material plays better sealing effect.Metal ferrules 6 is c-shaped, and it is large that metal ferrules 6 inwall is provided with protruding 10, C shape metal ferrules 6 deformation degree, and inwall is provided with protruding 10 and strengthens force bearing point.Under tightening force effect, sealing neck 5 is more fitted tightly with spiral corrugated stainless steel tubing, through hole 4 is T-shaped, through hole 4 top end diameter equals the diameter of spiral corrugated stainless steel tubing, through hole 4 bottom diameter is greater than outer nut 2 central bore diameter, outer nut 2 outer wall is hexagonal shaped, outer nut 2 central bore diameter is greater than the diameter of spiral corrugated stainless steel tubing, because through hole 4 top end diameter equals the diameter of spiral corrugated stainless steel tubing, the hydraulic pressure entering spiral corrugated stainless steel tubing from water knockout drum remains unchanged, and is convenient to the control of hydraulic pressure during work; Moreover through hole 4 bottom diameter is greater than outer nut 2 central bore diameter, gap can be there is between through hole 4 bottom and outer nut 2 central bore, through hole 4 bottom can be put in the lump after spiral corrugated stainless steel tubing is inserted in metal ferrules 6, pad 7, serve fixing effect.
The working principle of the present embodiment is as follows:
1) first spiral corrugated stainless steel tubing is screwed in sealing neck 5, until spiral corrugated stainless steel tubing port is apart from sealing 1mm place, neck 5 top;
2) be then inserted in pad 7 toward spiral corrugated stainless steel tubing to fit plain cushion 8, then be inserted in metal ferrules 6 and fit pad 7, be finally again inserted in pad 7 and fit metal ferrules 6, whole process ensures chamfering 9 the laminating metal ferrules 6 of pad 7, tentatively completes assemblying body;
3) assemblying body assembled is inserted fastening central body 1, spiral corrugated stainless steel tubing is inserted in outer nut 2 and screws, and along with outer nut 2 precession in fastening central body 1, metal ferrules 6 is tightened up, closed up by the chamfering 9 of two pads gradually.Sealing neck 5 presses down, tightens up by now metal ferrules 6 further, and suppressing action makes its powerful substantial laminating boss structure 3 inwall; The effect of tightening up makes its brute force enrich in the trench of helical corrugation, makes shipwreck to reveal, reaches the effect of sealing.
In sum, adopt a kind of linkage structure being applied to spiral corrugated stainless steel tubing provided by the present invention, can not realize the connection of spiral corrugated stainless steel tubing and water-outlet body by any professional tool, connection sealing is strong, easy to operate.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment made, equivalent replacement, improvement etc., all should be included within the scope of protection of the invention.
