The purpose of the present utility model can also be achieved through the following technical solutions:
The distance of described limiting block pitch of fins fixed dam is 3mm, and the thickness of spacing catch is 1mm.Described spacing catch is connected with fixed dam is curved, and its radius is 2mm, forms arc ring recess.Described draw-in groove is arranged on cutting ferrule front inner wall and is obliquely extended to apart from 5mm place, front end end, and the gradient of described draw-in groove is 10 degree.In described cutting ferrule, 3mm place, span front end end is provided with to the inclined-plane of outer wall inclination, and the gradient on described inclined-plane is 60 degree.
Compared with prior art, the utlity model has following beneficial effect:
1. tubing connection is safe and reliable, can not produce the situation of leak of liquid;
2. tubing joint is neat attractive in appearance, does not have damaged termination to extrude the problem of pipe fitting joint;
3. convenient and quick construction, working efficiency is further enhanced.
Accompanying drawing explanation

Fig. 2 is the utility model cutting ferrule schematic diagram;
Fig. 3 is that prior art connects PEX pipe design sketch;
Fig. 4 the utility model connects PEX pipe design sketch.
In figure: pipe fitting body 1, cutting ferrule 2, front end 2-1, joint 3, screw thread 4, spacing catch 5, fixed dam 6, clip slot 7, inclined-plane 8, PEX pipe 9, PEX tube end residue 9-1, ring recess 10.
Embodiment
Below in conjunction with drawings and Examples, the utility model essentiality content is described in further detail:
As shown in Figure 4: the cold expansion formula of the tight cutting ferrule of the effective cunning of a kind of spacing anticreep PEX pipe fitting, comprises pipe fitting body 1 and the cutting ferrule 2 supporting with it.As shown in Figure 1: pipe fitting body 1 is provided with at least one joint 3, according to the needs of construction, pipe fitting can be lead directly to, threeway or elbow, can be also the various ways such as isometrical or reducing.The fixed dam 6 of one end connection pipe fitting of joint 3, joint 3 is provided with spacing catch 5 at nearly fixed dam 6 places, and spacing catch 5 is connected with fixed dam 6 is curved, and its radius is 2mm, form arc ring recess 10, its effect is to manage the headspace after 9 ends are squeezed at PEX.Spacing catch 5 is 3mm apart from the distance of fixed dam 6, and the thickness of spacing catch 5 is 1mm.Joint 3 is provided with screw thread 4, and the diameter of spacing catch 5 is greater than the diameter of screw thread 4.Because PEX pipe 9 has plurality of specifications, so the external diameter of spacing catch 5, the external diameter of joint 3 screw threads 4 and the internal diameter of cutting ferrule 2 are all set by supporting different size PEX pipe.The diameter of joint 3 screw threads 4 is greater than the internal diameter of PEX pipe 9, utilizes PEX to manage 9 stretchabilities, and PEX pipe 9 is tightly enclosed within on the screw thread 4 of joint 3.As shown in Figure 2: the internal diameter of cutting ferrule 2 is less than the external diameter of the PEX pipe 9 on tight bell and spigot joint 3 screw threads 4, the inwall of cutting ferrule 2 front end ends is provided with the draw-in groove 7 that anti-PEX manages 9 slippages, draw-in groove 7 is arranged on cutting ferrule 2 front inner wall and is obliquely extended to apart from 5mm place, front end end, and the gradient of draw-in groove is 10 degree.3mm place, the interior span front end of cutting ferrule 2 end is provided with to the inclined-plane 8 of outer wall inclination, forms a horn mouth, and the gradient on inclined-plane 8 is 60 degree.
Embodiment: as shown in Figure 4: the end of PEX pipe 9 is cut neat, be tightly enclosed within on the screw thread 4 of pipe fitting joint 3, the end of PEX pipe 9 is resisted against on spacing catch 5.Put cutting ferrule 2, the front end 2-1 of cutting ferrule 2 aims at joint 3, and the internal diameter of cutting ferrule 2 is less than the PEX pipe 9 of cover upper connection 3 parts.Adopt sliding clamping tool by cutting ferrule 2 pressed joints 3, the fixed stop 6 of pipe fitting is directed reach in the end of cutting ferrule 2.In compressing the process of cutting ferrule 2, PEX manages 9 ends in extrusion process, owing to being subject to the retardance of spacing catch 5, only there is the PEX tube end through pushing on a small quantity to enter in the arc ring recess 10 of fixed stop 6 and 5 formation of spacing catch, and can not resemble, PEX is not managed prior art to 9 end 9-1 and extrude outside the gap of fixed stop 6 and cutting ferrule 2 end face combinations (referring to Fig. 3), as formed one seal ring, both guaranteed that PEX managed 9 end seals, can prevent again 9 slippages in high-pressure work of PEX pipe.In extrusion process, the concave surface forming between joint 3 screw threads 4 and the draw-in groove 7 of cutting ferrule 2 front ends are all clogged tubing, and the PEX pipe 9 in joint 3 and cutting ferrule 2 is tightly wrapped on joint 3, guarantee that PEX pipe 9 is connected with pipe fitting safe and reliable.
