Each latch stretches out towards the inner of body, and is partial to the plastic tube direction, and plastic tube inserts along the plane of inclination of latch, and latch is backed down to dog collar outer ring direction.Latch play the guiding role when plastic tube inserts, and utilizes the reset function of self to act on the plastic tube after connection is finished, and plays the effect of fixed plastics pipe.
As a kind of preferred, the outer end that described body is used to insert plastic tube is provided with the intubate of a tubulose, and the inner of intubate is inserted in the body.Plastic tube passes intubate and is inserted in the body, and intubate is socketed on the plastic tube, prevents that plastic tube from rocking.
As a kind of preferred, the inner of described intubate is provided with circumferential clasp, and the outer end of body is the conical surface shape that shrinks gradually, and the internal diameter of snap ring is identical with the internal diameter of intubate, external diameter is greater than the aperture of body outer end port, and the outer side surface of above-mentioned snap ring is provided with the annular slope that matches with the latch that tilts.
Snap ring plays position-limiting action, prevents that intubate from spinning off from body.Only need during dismounting intubate is pressed into, the annular slope of snap ring is acted on the plane of inclination of latch, each latch is backed down to dog collar outer ring direction, latch and plastic tube surface is broken away from, can in body, extract plastic tube out.
As a kind of preferred, described each latch annular be evenly distributed on the dog collar and the angle of inclination identical.The angle of inclination of each latch is identical, and is circumferential setting, form one round table-like, circumferentially stepless action is played more stable fixation on the plastic tube surface.
As a kind of preferred, described positioning step comprises the step one and the step two of the annular of stepped setting, and the internal diameter of step one is greater than the internal diameter of step two, and above-mentioned dog collar is resisted against on the step one, and above-mentioned seal ring is fixed between step two and the dog collar.
As a kind of preferred, be provided with packing ring between described step one and the dog collar, the side that packing ring contacts with dog collar is provided with the interior inclined-plane that matches with the latch that tilts.Packing ring and step two are clipped in the middle seal ring and fix.
As a kind of preferred, be provided with the sleeve pipe of conical surface shape between described intubate and the body, described casing pipe sleeve is connected on the intubate, and the external diameter of above-mentioned snap ring is greater than the endoporus aperture of sleeve pipe small end, and the external diameter of the big end of sleeve pipe is then greater than the aperture of body outer end port.Can make between intubate and the body compacter behind the mounting sleeve.
Compared with prior art, this rapid pipe joint belongs to plug and play type, and plastic tube inserts the own latch in back and fixes, and does not need other follow-up work, installs simple and convenient.Only need inwardly be pressed into intubate during dismounting latch is unclamped, the convenient plastic tube of extracting out.And also do not need to use raw meal belt to seal in the joint, seal operation is finished by the seal ring of body interior, relatively environmental protection.

Embodiment
As shown in Figure 1, this inserted type quick coupling comprises the body 1 with tubulose, and the inwall of body 1 is stepped, has the step 1 and the step 2 12 of annular, and the internal diameter of step 1 is greater than the internal diameter of step 12.Axially be provided with intubate 2, dog collar 3, packing ring 4 and the seal ring 5 of tubulose in the body 1 successively, packing ring 4 is resisted against on the step 1, and seal ring 5 then is clipped between packing ring 4 and the step 2 12.
Shown in Fig. 2～4, the side that packing ring 4 contacts with dog collar 3 is provided with interior inclined-plane 41.Be fixed with circumferential clasp 21 on the intubate 2 of tubulose, the outer end of body 1 is the conical surface shape that shrinks gradually, and the internal diameter of snap ring 21 is identical with the internal diameter of intubate 2, and external diameter is greater than the aperture of body 1 outer end port, and the outer side surface of snap ring 21 is provided with annular slope 21a.
The inside of body 1 is provided with the sleeve pipe 6 that is similarly conical surface shape, and sleeve pipe 6 is socketed on intubate 2, dog collar 3 and the packing ring 4, and has fixture block 61 on the inwall of sleeve pipe 6, and fixture block 61 is fixed packing ring 4 and dog collar 3 with step 1.The external diameter of above-mentioned snap ring 21 is greater than the endoporus aperture of sleeve pipe 6 small ends, and the external diameters of sleeve pipe 6 big ends are then greater than the aperture of body 1 outer end port.
As shown in Figure 5 and Figure 6, has the latch 31 that several adopt tinsel to make on the internal diameter of dog collar 3, each latch 31 tilts to stretch out towards dog collar 3 axis directions, and towards the inner of body 1, the interior inclined-plane 41 of above-mentioned packing ring 4 and the annular slope 21a of snap ring 21 all match with inclination latch 31.In the present embodiment, the angle of inclination of each latch 31 is identical, form one round table-like, circumferentially stepless action is on the plastic tube surface.
As shown in Figure 7, this rapid pipe joint can be applicable in the threeway, only needs the inner of body 1 adopted the interface of technology such as welding and threeway to be connected and gets final product.
When needs utilized this threeway that has rapid pipe joint that several plastic tubes are connected, plastic tube was inserted in the body 1, passes intubate 2, dog collar 3, packing ring 4 and seal ring 5 successively.The size of the small end port of the round platform that latch 31 forms is littler than plastic tube size, thereby plastic tube can slide along the plane of inclination of latch 31 during insertion, in the sliding process latch 31 is outwards strutted, because each latch 31 adopts tinsel to make, thereby has certain elasticity, can open to dog collar 3 outer rings under the effect of plastic tube end, the elastic reaction that can utilize self is again fixed plastic tube on the plastic tube surface.
Only need during dismounting intubate 2 is pressed into, the annular slope 21a of snap ring 21 is acted on the plane of inclination of latch 31, each latch 31 is backed down to dog collar 3 outer ring directions.Latch 31 breaks away from the plastic tube surface, can extract plastic tube out in body 1.
Same principle connects plastic tube if desired on valve, as long as at the water intake or the water outlet place of valve this class joint is installed, can easily plastic tube be connected with valve.
