Description
Technical field
The utility model relates to the interconnection technique field of fibre reinforced composite tubes, specifically a kind of linkage structure of fibre reinforced composite tubes.
Background technique
At present, the Placement of fibre reinforced composite tubes has: socket joint connection, screwed connection, the nut of living connect.The female end that socket joint connects needs inner circle enlarging, and bellmouth need to be smeared adhesive with socket surface in the time being connected and seal, high to construction environment requirement, complex operation.The internal thread connecting end of screwed connection needs enlarging equally, and adopts the composite pipe in pipeline stage casing of screwed connection to need to rotate, and in the time connecting and need to rotate whole tubing while dismounting and just can complete and be connected or dismantle, its working strength is large, and installation cost is high.Active connection is at the bonding inipple in one end of composite pipe, the bonding joint with the nut of living of the other end, between joint, connect by the nut of living, when the bonding of the joint of active connection and composite pipe termination, first to polish after the tapering conforming to joint endoporus at pipe end, between joint and tubing, smearing adhesive bonds, object is that to utilize squeezing action between the conical surface that adhesive between joint and tubing is filled up substantial, and the conical surface has also played positioning action.But bruting process wastes time and energy, and polish the enhancement layer of pipe end is caused to the join strength of damage influence joint, generally thinner for low pressure tubing enhancement layer thickness, part tubing cannot be polished because enhancement layer is too thin.
Summary of the invention
The purpose of this utility model is the deficiency that solves above-mentioned technology, proposes one simple in structure, and pipe end is without polishing and low cost of manufacture, the linkage structure of the fibre reinforced composite tubes that join strength is high are installed easily.
The technological scheme that the utility model adopts is: a kind of linkage structure of fibre reinforced composite tubes, comprise that connection end has the composite pipe of sealing positioning table, it is characterized in that being provided with joint I, joint II, attaching nut, seal retainer ring, joint I, the inner circle of joint II is respectively with tapering, inner circle is provided with annular groove, in joint I, in the tail end of joint II, be respectively equipped with shoulder hole, in shoulder hole, be provided with seal retainer ring, on the termination cylindrical of joint I and joint II, be respectively equipped with step, the termination cylindrical step of joint II is provided with connecting thread, joint I is seam with joint II end and coordinates location, joint I, junction, joint II termination is provided with attaching nut, joint I is connected with joint II is active.
Annular groove indention shape in described joint I, joint II inner circle, the angle on zigzag fashion inclined-plane is 15 °-30 °, tooth pitch is 5mm-20mm.
The utility model is reasonable in design, simple in structure, installs easily, and labor intensity is low, and working efficiency is high, and join strength is high, long service life.
