Fast connecting joint described in the utility model, wherein, the quantity of conical through-hole and steel ball is identical and respectively be eight.
Fast connecting joint described in the utility model wherein, describedly ejects circumferential four through holes that communicate with its endoporus that evenly are provided with on the right part periphery.
After adopting above structure, compared with prior art, the utility model fast connecting joint has the following advantages: when disconnecting pipeline, owing to have air cavity, can feed gas to air cavity by tracheae, sliding sleeve is moved to the left, finished the work that manually is moved to the left sliding sleeve, and owing to have ejector spring, can make eject the tube move right, thereby butt joint is ejected automatically, has realized the effect of automatic disconnection pipeline fast connecting joint, and can feed the purpose that gas reaches the disconnection fast connecting joint to air cavity by telecontrol.
Four through holes that eject a right part setting can make and eject that formed enclosed cavity communicates with the endoporus that ejects tube between a right part and the female joint endoporus, when ejecting tube when moving right, can make medium in the enclosed cavity timely in the flow ipe, thereby reduce the resistance of ejector spring, better butt joint is ejected.

Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model fast connecting joint is described further:
As depicted in figs. 1 and 2, in this embodiment, the utility model fast connecting joint comprises female joint 1, butt joint 2, sliding sleeve 3, steel ball 4, spring 5, jointing 6, ejector spring 7, eject tube 8, cylinder cap 9, tracheae 11 and air cavity 10, female joint 1 periphery middle part is provided with a convex shoulder 12, it is outer and can endwisely slip on the periphery of the right-hand member periphery of female joint 1 and convex shoulder 12 that sliding sleeve 3 is enclosed within female joint 1, be provided with O-ring seals between the periphery of convex shoulder 12 and sliding sleeve 3 endoporus, circumferential eight conical through-holes 14 that communicate with its endoporus that evenly are provided with on the female joint 1 right part periphery, all be placed with a steel ball 4 in each conical through-hole 14, spring 5 one ends withstand on the right side of convex shoulder 12, and the other end withstands on the step surface in sliding sleeve 3 endoporus.Butt joint 2 left part peripheries slidably are connected with female joint 1 right part endoporus, and female joint 1 right part endoporus and butt joint 2 left part periphery connections are provided with O-ring seals, when butt joint 2 left part peripheries are inserted into female joint 1 right part endoporus, be provided with an annular groove 16 that steel ball 4 is entered with conical through-hole 14 cooperation places on the butt joint 2 left part peripheries.The right-hand member periphery of jointing 6 is connected with the left end inner hole thread of female joint 1, and the joint is provided with O-ring seals.Ejector spring 7 one ends withstand on the step surface of jointing 6 endoporus, the other end withstands on the endoporus step surface that ejects tube 8, ejecting tube 8 is arranged in female joint 1 inner chamber and can axially slides at the endoporus of female joint 1, and the right side that ejects tube 8 can eject butt joint 2, and ejects circumferential four through holes 17 that communicate with its endoporus that evenly are provided with on the tube 8 right part peripheries.Cylinder cap 9 is enclosed within female joint 1 outside and can moves axially on the periphery at female joint 1 middle part, and be provided with O-ring seals between the periphery at the endoporus of cylinder cap 9 and female joint 1 middle part, cylinder cap 9 and sliding sleeve 3 are connected by screw, and be provided with gasket seal 13 between the left side of the right side of cylinder cap 9 and sliding sleeve 3, air cavity 10 is the toroidal cavities that surrounded by female joint 1, cylinder cap 9 and sliding sleeve 3, cylinder cap 9 is provided with passage 15, passage 15 1 ends communicate with air cavity 10, and the other end communicates with tracheae 11 by inipple.
The working principle of the utility model fast connecting joint is: when connecting pipeline, the user is moved to the left sliding sleeve 3 earlier, make spring 5 be in compressive state, and make steel ball 4 be in free state, at this moment butt joint 2 is inserted in the endoporus of female joint 1, at this moment butt joint can promote to eject tube and 8 is moved to the left, and make ejector spring 7 be in compressive state, and then unclamp sliding sleeve 3, sliding sleeve 3 meetings move right under the effect of the restoring force of spring 5, till the cylinder cap 9 that is connected with sliding sleeve 3 is run into convex shoulder 12, at this moment steel ball 4 can be pressed in the annular groove that is provided with on the butt joint 2 by sliding sleeve 3, thereby finish the connection of two pipelines, in the time will disconnecting pipeline, at first feed gas by 11 pairs of air cavitys of tracheae 10, at this moment under the effect of air pressure, cylinder cap 9 and sliding sleeve 3 are moved to the left, make spring 5 be in compressive state, and make steel ball 4 be in free state, at this moment the ejector spring 7 that is in compressive state moves right under the effect of restoring force butt joint 2 is ejected from the endoporus of female joint 1, thereby finishes the disconnection work of pipeline.
