Background technique
Metal hose joint is a kind of high-quality flexible pipe in the modern industry pipeline.It mainly is comprised of MOLLET metal hose joint bellows, net and joint.Its inner tube is the thin-wall stainless steel bellows with spirality or annular, and the outer field net of bellows is to be formed by certain parameter braiding by Stainless Steel Wire or steel band.The joint at flexible pipe two ends or flange are to match with joint or the flange of client's pipeline.The bellows of flexible pipe is that the seamless or many weldering stainless-steel pipes by wall as thin as a wafer are shaped through the highi degree of accuracy plastic working.Because the elastic characteristic of bellows profile has determined that flexible pipe has good ductility and fatigue resistance, make it be easy to absorb the cyclic loading of various motion deformations, the ability of compensation big displacement quantity is especially arranged in pipe-line system.
For example, Chinese patent literature discloses a kind of hose coupling [application number: CN201220316989.3], be included as holistic flexible pipe linkage section, for spanner, block the hexagonal shell of column tightened and for being screwed into the thread section in the hydraulic equipment tapped hole, the hexagon prism section is positioned between flexible pipe linkage section and thread section, the hexagonal shell of column is comprised of six planes, six planes surround regular hexagon, and wherein, the middle part on six planes all has axial notch.When the utility model hose coupling is used spanner to be tightened operation people, be difficult for causing spanner to skid.
Although such scheme has linkage function, still exist design reasonable not, complex installation process, restricted application need to be installed according to specific order in installation.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and activity male connection hose a kind of reasonable in design, simple in structure, easy for installation is provided.
For achieving the above object, the utility model has adopted following technical proposal: this activity male connection hose, comprise flexible pipe, be inserted with adapter in the end of flexible pipe, the riveting sleeve that flexible pipe and adapter can be fixed together is arranged at the end of flexible pipe overcoat, it is characterized in that, described adapter outer race has male connection, is provided with between described adapter and male connection and can makes the male connection axial limiting and circumferentially be arranged on rotationally the linkage structure in adapter.
In above-mentioned activity male connection hose, described linkage structure comprises annular convex shoulder and the annular groove that is arranged on the adapter outside and is set up in parallel, described male connection is provided with the annular retaining ring between annular convex shoulder and annular groove, on described annular groove, is connected with collar.
In above-mentioned activity male connection hose, also be provided with sealing configuration between described adapter and male connection.
In above-mentioned activity male connection hose, described sealing configuration comprises at least one O type groove be arranged in adapter, in described O type groove, is equipped with at the O type circle of taking between the outside and male connection inboard.
In above-mentioned activity male connection hose, described riveting sleeve the inner is socketed on flexible pipe, and outer end coats hose end and is buckled in and takes over above, and described riveting sleeve middle part is shunk also flexible pipe is pressed in adapter.
In above-mentioned activity male connection hose, described flexible pipe comprises interior tube body and is located at the woven sheath in the interior tube body outside.
Compared with prior art, the advantage of this activity male connection hose is: reasonable in design, simple in structure, easy for installation, in installation, without carry out the connection of joint according to specific order, long service life, connect reliably good airproof performance.
