Description

Swivel coupling of the quick-acting type

The relevant a kind of rotatable rapid pipe joint of the utility model.

The quick coupling structure of generally commonly using mostly can't rotate, therefore when using, conduit is turned round to be rolled into one and cause and use last inconvenience, if desire to make reluctantly its rotation then very easily to make pipe joint or conehead link produce wearing and tearing, and make rapid pipe joint promptly produce the phenomenon of gas leakage in when extremely short, cause air compressor make-up gas and consume electric power often, and must change rapid pipe joint often and cause puzzlement.

Therefore, the purpose of the utility model is to provide a kind of rotatable rapid pipe joint, and its junction point sealing property is good, is not subjected to impeding of conduit during use and can produces rotation, can not produce wearing and tearing and causes gas leakage, long service life and convenient.

The purpose of this utility model system reaches by following rotatable rapid pipe joint, it mainly is by joint tail cover, ball, rotating ring, pipe joint, C type clamp ring, link, rubber washer, spring, ferrule piece, ring set, the rubber plug ring, member such as fastener and headgear is formed, in joint tail cover, be equiped with a plurality of balls and with in the rotating ring configuration joint tail cover, and the mat ball make rotating ring in joint tail cover generation as the effect of bearing rotation, place the pipe joint of a tool concave-concave annular groove in the joint tail cover and the central hole of rotating ring, and pull with C type clamp ring folder and but pipe joint and rotating ring snapping one and one to be rotated in the wherein groove of this pipe joint, make it can produce rotation in use and be not subjected to conduit holding up or making reluctantly pipe joint or conehead link to produce the friction rotation and make junction point produce wearing and tearing and leak gas, this joint tail cover system is rotatably connected in one of the link of two ends tool screw thread end, this moment, another scrobicular ring slot part of this pipe joint front end just penetrated in the hole of link, mat one rubber washer is placed on the scrobicular ring slot part of pipe joint front end, and the junction point that makes pipe joint and link reaches splendid sealing property, in link, be provided with a ferrule piece that is subjected to spring restoring force and tool hole, establish the ring set that an inside is provided with a rubber plug ring in link front end lock, this ferrule piece system is subjected to the elastic force of spring and its tool hole position is allocated in hole within the rubber plug ring gas by pipe joint importings is broken among this produces temporarily, continuous lock is established a headgear on ring set, in this headgear, be provided with a fastener that is subjected to spring restoring force and central tool elongated hole, after the conehead link that is locked on pneumatic tool inserts headgear, then the elongated hole edge of mat fastener is buckled the circular groove of pulling in the conehead link, and simultaneously the tapered end of mat conehead link is passed ferrule piece its hole is exposed within the rubber plug ring outside the hole, and make gas via the hole of ferrule piece by and cause pneumatic tool via the conehead link, when desiring to make the conehead link to separate with rapid pipe joint, only must push this fastener makes its elongated hole edge separate with the circular groove of conehead link and mat is subjected to the ferrule piece ejection of spring restoring force and the conehead link is separated with fast kinetic head, and the tool hole portion that makes this ferrule piece is composite goes into hole within the rubber plug ring and make gas halts, the pipe joint that mat can produce rotation is not subjected to impeding of conduit in use and can produces rotation, does not produce wear phenomenon and reaches effect easy to use and life-span length.

After below in conjunction with accompanying drawing the utility model being described in more detail in.
