Description
Technical field
The utility model relates to a kind of hose coupling, is a kind of integrative soft pipe joint specifically, for delivery of hydraulic oil, is applicable to the high-pressure work environment of daily production.
Background technique
At present, hose joint is widely used in the various high pressure of engineering machinery, mining machinery, boats and ships, metallurgy, wind-powered electricity generation and other industry, the hydraulic system of high reliability request, for delivery of liquid, the winding hose coupling of selling on market, great majority are split type, large specification to shell glue, sleeve kind is many, and versatility is poor, easily obscures, outer connector easily drops, and is inconvenient to manage.At present, Chinese patent discloses a kind of hose coupling [notice of authorization CN 201992231 U] of fastening-pressing type, this hose coupling is split type, while selecting hose coupling, select the sleeve matching, troublesome poeration, also can cause the outer connecting end accessory of hose coupling to drop sometimes, is not easy to management.
Summary of the invention
The purpose of this utility model is the problem for above-mentioned existence, provides a kind of integrated sealing reliable, and highly versatile can bear the winding hose coupling of the fastening-pressing type of high pressure.
The utility model solves by following technical proposal: comprise and be provided with axial hole, flexible pipe butt end, the fittings body of changeover portion and threaded pipe butt end, nut, , Sealing, wherein the threaded pipe craft port of fittings body is provided with the conical surface and bulge loop, coordinate with external connection screw pipe joint, the conical surface is provided with seal groove and coordinates with Sealing, bulge loop coordinates with the nut being enclosed within on changeover portion, external connection screw pipe joint and nut, the conical surface, O type circle closely cooperates, changeover portion the other end place is provided with sleeve connecting groove and coordinates with a sleeve, sleeve is provided with flexible pipe abutting end, sleeve cylinder shoulder and pre-end of thread, flexible pipe abutting end is provided with tooth and coordinates with external winding flexible pipe, on the conical surface taking symmetrical two the angle a that sideline was formed of through-bore axis as 20 °-30 °.
On the described conical surface taking symmetrical two the angle a that sideline was formed of through-bore axis as 24 °.
The beneficial effects of the utility model be the inner conical surface of outer jointing by nut check, it is tightly fitted on the male cone (strobilus masculinus) of fittings body, make on male cone (strobilus masculinus) to obtain the extrusion-deformation of O type circle simultaneously, play double seal effect, thereby reach leak free unfailing performance.Sleeve is by after withholding, and spiral rubber hose extrusion-deformation, inserts in the tooth of sleeve and fittings body it, combines together, reaches sealing effect, and anti-pulling-and-doffing performance energy, prevents dust entered function.Like this, not only improve the working pressure of bearing of hose assembly, and improved its high life.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, this embodiment comprises and is provided with axial hole 1.6, flexible pipe butt end 1.5, the fittings body 1 of changeover portion 1.3 and threaded pipe butt end, nut 3, O type circle 4, wherein the threaded pipe craft port of fittings body 1 is provided with male cone (strobilus masculinus) 1.1 and bulge loop 1.2, male cone (strobilus masculinus) 1.1 is provided with seal groove and coordinates with O type circle 4, bulge loop 1.2 coordinates with the nut 3 being enclosed within on changeover portion 1.3, external connection screw pipe joint 7 and nut 3, male cone (strobilus masculinus) 1.1, O type circle 4 closely cooperates, sleeve 2 is provided with flexible pipe abutting end 2.1, sleeve cylinder shoulder 2.2 and pre-end of thread 2.3, flexible pipe abutting end 2.1 is provided with tooth and coordinates with external winding flexible pipe 5, changeover portion 1.3 the other end places are provided with sleeve connecting groove 1.4 and coordinate with the pre-end of thread 2.3 of sleeve 2, on male cone (strobilus masculinus) 1.1 taking symmetrical two the angle a that sideline was formed of through hole 1.6 axis as 20 °-30 °.
On described male cone (strobilus masculinus) taking symmetrical two the angle a that sideline was formed of through-bore axis as 24 °.
In assembly process, sleeve 2 is to be processed by turning by forging stock, after first nut 3 being packaged, then it is buckled on fittings body in advance, can avoid like this nut 3 not fill, and also can prevent from dropping.After buckling well in advance, sleeve can not spin on fittings body, otherwise, may pull-off or leakage.
From Fig. 5, the inner conical surface of outer jointing, by nut check, is tightly fitted on the male cone (strobilus masculinus) 1.1 of fittings body it, makes to obtain the extrusion-deformation of O type circle on male cone (strobilus masculinus) 1.1 simultaneously, plays double seal effect, thereby reaches leak free unfailing performance.Sleeve is by after withholding, and spiral rubber hose 5 extrusion-deformations, insert in the tooth of sleeve 2 and fittings body 1 it, combine together, reach sealing effect, and anti-pulling-and-doffing performance energy, prevents dust entered function.Like this, not only improve the working pressure of bearing of hose assembly, and improved its high life.
