Detailed description of the invention

As schemed shown in l ~ 3, the embodiment of the present invention includes: a kind of fast insert-pull joint, including: interior valve union 3 and interfaced outer valve union 2, described interior valve union 3 is provided with spring spool 31, spring spool is pressed in runner mouth, interior valve union fluid stopping under the effect of back-moving spring 33; Described outer valve union 2 axle center is provided with spring valve plug 21, and spring valve plug is then held out against runner mouth by elastic force, and outer valve union is inaccessible; SANYE flap 33 and the spring valve plug 21 of described spring spool 31 end push up pressure mutually, make the runner mouth that spring spool 31 is closed with it produce gap; The runner mouth that spring valve plug 21 is closed with it also produces gap, thus the center flow channels in joint is through; Described interior valve union 3 and outer valve union 2 are connected by buckling and locking device l; Described buckling and locking device l includes: shackle casing 11, play top cover 12 and the moon shape key 13; Shackle casing is placed on the junction of outer valve union flexibly, plays top cover and is then placed on the junction of interior valve union flexibly.

Being provided with axle spring 14 in described bullet top cover 12 inner chamber, axle spring is supported on the shaft shoulder of interior valve union 3 junction; Described shackle casing 11 also is provided with axle spring with the place of cooperation of outer valve union 2. The described moon, shape key 13 was formed by connecting by arc elastic sheet by two connecting keys that work surface is relative. The outer wall of described outer valve union 2 junction is provided with groove; The described moon, shape key was placed in groove; The outer wall of described interior valve union 3 junction is provided with gap slot 35, and the position of gap slot is corresponding with groove position on described outer valve union; Described gap slot 35 13 can coordinate with moon shape key; Shackle casing 11 outside described outer valve union can be radially spacing to moon shape key 13, and the inner diameter ecto-entad of described shackle casing and moon shape key contacts position successively decreases gradually.

During use, being docked mutually with outer valve union 2 by interior valve union 3, the spring valve plug 21 in outer valve union pushes up pressure mutually with the spring spool 31 in interior valve union, makes whole runner through. Now, the moon shape key on outer valve union 13 is just stuck on the gap slot 35 of interior valve union, and shackle casing 11 then blocks a moon shape key 13 under the effect playing top cover 12, makes moon shape key radially spacing. So, interior valve union 3 and outer valve union 2 body compact siro spinning technology, will not unclamp. When needs break connector, only quickly need to move to right unloading hitch 11, change due to shackle casing inner diameter, the restraining ability of moon shape key 13 is weakened by shackle casing, the moon shape key radially unfold under its own resilient effect, then the moon, shape key 13 disengaged from gap slot 35, inside and outside valve union body is separated, spring valve plug 21 and the spring spool 31 of interior valve union within outer valve union reset under the effect of respective spring force, and keep runner to seal by sealing ring, and fluid circuit disconnects.

The present invention provides a kind of fast insert-pull joint, and when this fast insert-pull joint is off, outer valve union therein and interior valve union are respectively at automatic-sealed state. During docking then automatically through, coordinate precision, and reliable and stable. Adopt the limit method that key connects to carry out self-locking at the inside and outside joint connecing valve head, utilize shackle casing and play top cover and coordinate moon shape key, the moon shape key, outer valve union and interior valve union are fixed, it is achieved rapid abutting joint, and ensure its sealing property.

The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every equivalent structure utilizing description of the present invention to make or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, all in like manner include in the scope of patent protection of the present invention.
