Description

A kind of pipe joint
Technical field
The utility model relates to a kind of pipe joint that is used for connecting pipeline.
Background technique
It all is that the unified engage thread of inside and outside coupling of using connects that existing pipeline connects, and the pipe joint structure of this engage thread is single, will tie up the waterproof sealing band during pipeline butt joint, and dismounting is loaded down with trivial details, and speed is slow.
Summary of the invention
The goal of the invention of the utility model provides a kind of novel structure, and dismounting is pipe joint fast.
In order to reach the foregoing invention purpose, the utility model adopts following technological scheme:
A kind of pipe joint comprises tube end, seal ring, circular mounting head and snap close, and seal ring is installed in the tube end inboard, and the mouth of pipe of tube end is the anticreep mouth that internal diameter dwindles from the inside to the outside; The circular mounting head is installed on the anticreep mouth of tube end, and promptly the outer ends of circular mounting head is in the anticreep mouth outside, and it is inboard that inner end extends the anticreep mouth; Said circular mounting head is connected as a single entity by a plurality of arc dops of the circular mounting ring of outer end and inner end and constitutes; The corresponding also circumferential array with anticreep mouth place madial wall of a plurality of arc dops ringwise; Be equipped with on a plurality of arc dop outer side walls and the corresponding anticreep boss of anticreep mouth place madial wall, be equipped with the metal card article on a plurality of arc dop madial walls; The outer side wall of circular mounting ring is provided with annular boss, and snap close is stuck on the circular mounting head of the anticreep mouth outside and annular boss inboard.
As preferably, the annular boss that the outer side wall of said circular mounting ring is provided with the radially outward protrusion and is connected as a single entity with its outer side wall.
As preferably, the quantity of said arc dop is between 3-7.
As preferably, said anticreep boss and arc dop outer side wall are connected as a single entity.
Adopt the pipe joint of said structure, pipe joint comprises tube end, seal ring, circular mounting head and snap close, and the mouth of pipe of tube end is the anticreep mouth that internal diameter dwindles from the inside to the outside, and the circular mounting head is installed on the anticreep mouth of tube end.Circular mounting head wherein is connected as a single entity by a plurality of arc dops of the circular mounting ring of outer end and inner end and constitutes; Corresponding and the circumferential array of the madial wall at a plurality of arc dops and anticreep mouth place ringwise; Be equipped with on a plurality of arc dop outer side walls and the corresponding anticreep boss of anticreep mouth place madial wall, be equipped with the metal card article on a plurality of arc dop madial walls.When external connecting pipe connected, connecting tube ran through the circular mounting head seal ring inboard with being located at tube end successively.When passing the metal card article, above-mentioned a plurality of arc dop radially outward elasticity are opened, run through the seal ring sealing again.The rollback connecting tube makes the metal card article be clamped on the connecting tube outer side wall; Anticreep boss on the arc dop tightly is stuck on the anticreep mouth; Because the internal diameter of anticreep mouth dwindles from the inside to the outside; So connecting tube rollback stroke is big more, drives the circular mounting head and outwards move and just make the anticreep boss be stuck in to block tightly more on the anticreep mouth.Know that according to above-mentioned the pipe joint advantage of this structure is a novel structure, connect between pipeline fast and convenience, substitute the pipe joint of engage thread, good connecting effect.
Description of drawings

Fig. 2: the perspective view of circular mounting head among the embodiment.
Embodiment
Be to combine above-mentioned accompanying drawing that the technological scheme of the utility model is described in further detail below.
A kind of pipe joint as depicted in figs. 1 and 2 comprises tube end 13, seal ring 12, circular mounting 10 and snap close 11, and seal ring 12 and circular mounting 10 is installed in tube end 13, and snap close 11 is locked on the circular mounting 10.
The mouth of pipe of tube end 13 is anticreep mouths 131 that internal diameter dwindles from the inside to the outside, and the internal diameter at tube end 13 mouth of pipe places specifically is that linearity is dwindled, and anticreep mouth 131 is tapered.Circular mounting 10 is installed on the anticreep mouth 131 of tube end 13, and promptly the outer ends of circular mounting 10 is in anticreep mouth 131 outsides, and inner end extends anticreep mouth 131 inboards.Above-mentioned seal ring 12 specifically is mounted in tube end 13 inboards; Its position is in the inboard of circular mounting 10; The left side that is in circular mounting 10 just as shown in fig. 1, its mounting type can be to install through conventional mounting groove on tube end 13 madial walls or reducing mounting platform.Circular mounting 10 is connected as a single entity by a plurality of arc dops 101 of the circular mounting ring 102 of outer end and inner end and constitutes.The corresponding also circumferential array with anticreep mouth 131 place's madial walls of a plurality of arc dops 101 ringwise; Be equipped with the anticreep boss 101b corresponding with anticreep mouth 131 place's madial walls on a plurality of arc dop 101 outer side walls, anticreep boss 101b and arc dop 101 outer side walls are connected as a single entity.Be equipped with metal card article 101a on a plurality of arc dop 101 madial walls, metal card article 101a specifically is the curved metal bar that matees with arc dop 101 madial walls.The annular boss 102a that the outer side wall of circular mounting ring 102 is provided with the radially outward protrusion and is connected as a single entity with its outer side wall.Snap close 11 positions are between anticreep mouth 131 and the annular boss 131a, and snap close 11 is stuck on the inboard circular mounting of anticreep mouth 131 outsides and annular boss 131a 10, and snap close 11 specifically can be that shape takes the shape of the letter U or the buckle of open loop-shaped.
When connecting tube was installed, what select for use was the internal diameter coupling of external diameter and above-mentioned circular mounting ring 102, the plastic flexible pipe that also matees with the ringwise a plurality of arc dops 101 of circumferential array.Earlier snap close 11 is taken off, again connecting tube end 13 is inserted, run through circular mounting 10 and seal ring 12 successively.When passing metal card article 101a, above-mentioned a plurality of arc dop 101 radially outward elasticity are opened, run through seal ring 12 again and accomplish sealing.The rollback connecting tube makes metal card article 101a be clamped on the connecting tube outer side wall again, and the anticreep boss 101b on the arc dop 101 tightly is stuck on the anticreep mouth 131, and the rollback stroke is big more, just on anticreep mouth 131, blocks tightly more.Snap close 11 is stuck on the inboard circular mounting of anticreep mouth 131 outsides and annular boss 131a 10 and makes connecting tube not deviate from again.
The quantity of above-mentioned arc dop 101 is not limited to a plurality of, can also be in any amount between 3-7.Quantity is less than 3, connects low precision and insecure; Quantity is during far more than 7, and cost of production is very high.
