Ready-packaged joint can be realized the function that immediate shipment promptly seals, immediate shipment is kayser, is widely used in pipeline and connects in the engineering.It is made up of two-part, comprises connecting head and straight joint, can accomplish after the connection that both rotate at any angle.Since straight joint be by screw-threaded coupling on connecting head, and connect by riveted joint wedge mouth, adopt the sealing of metal covering to metal covering, therefore assembling is comparatively loaded down with trivial details, sealing effect is poor, and is easy to wear, causes ready-packaged joint short working life.
The model utility content
The technical problems to be solved in the utility model provides a kind of ready-packaged joint, and assembly manipulation is simple, good sealing effect.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: this ready-packaged joint comprises connecting head and straight joint, described connecting head inside is provided with through hole I, described straight joint inside is provided with through hole II, described straight joint is installed in the through hole I and flexibly connects with connecting head, described connecting head comprises connecting sleeve, back-up ring, shield ring sleeve, the back-up ring seat, described connecting sleeve is nut type and the outside is provided with screw thread, described through hole I is positioned at connecting sleeve and is stepped shaft, described connecting sleeve bottom is provided with annular recess I, described through hole I prolongs annular recess I place and forms the ladder mouth, described shield ring sleeve is installed on the ladder mouth, described shield ring sleeve outside is provided with annular projection I and the relative slot that radially is horizontal symmetrical, described back-up ring seat is the U type, described shield ring sleeve outside is with back-up ring, the top of described back-up ring inboard is provided with annular projection II, the bottom of described back-up ring inboard is provided with annular projection III, described back-up ring embeds in the annular recess I by annular projection II and is connected with connecting sleeve, described shield ring sleeve is limited between connecting sleeve and the back-up ring over against described connecting sleeve bottom and annular projection III simultaneously by annular projection I, described straight joint middle part is provided with seal ring I, described straight joint bottom is provided with annular groove II, described straight joint bottom is provided with round table surface I, described straight joint is by being tightly connected between seal ring I and the connecting head, and described back-up ring seat opening both sides embed in the annular groove II by slot.
As a kind of improvement of the present utility model, described connecting sleeve inner annular is distributed with stores up oily groove, and described grain bin oil groove is over against seal ring I, and described straight joint also is provided with seal ring II in the bottom of seal ring I.The sealing oil of in storing up oily groove, packing into, when work sealing oil can along with seal ring I rotate and infiltration around whole seal ring I, improve the sealability of seal ring I; The seal ring II of Zeng Jiaing provides more sealing guarantee for ready-packaged joint simultaneously, thereby makes ready-packaged joint have the sealing mechanism of flexibility, difficult wearing and tearing, good airproof performance.
As another kind of improvement the of the present utility model, the cross section of described annular groove II is trapezoidal, all be provided with the excessive face of round table surface between described through hole I adjacent apertures different piece, described straight joint is provided with the round table surface II of corresponding described excessive face in the bottom that is positioned at seal ring II.Because straight joint is to insert in the connecting head with very big power during the ready-packaged joint assembling,, be unlikely to the parts of damage ready-packaged joint under forceful action so after passing through the slow contact of each round table surface after the insertion, unnecessary power is offset.
The utility model adopts technique scheme, and the ready-packaged joint assembly manipulation is convenient, is connected firmly, and is safe in utilization; Good airproof performance, and not easy to wear, long service life.
