Description
Technical field
The utility model belongs to the cutting ferrule technical field, specifically relates to a kind of cutting ferrule that is used for flexible pipes such as nylon tube or polyurethane pipe and metallic pipe coupling.
Background technique
The nonmetallic pipe that nylon tube or polyurethane pipe etc. have certain plasticity is when being connected with metallic pipe coupling; Because pipes such as nylon tube or polyurethane pipe are prone to deform and wear out and cause nylon tube or polyurethane pipe to come off from pipe joint easily; For nylon tube or polyurethane tube and tube joint are connected firmly; Normal use fastening pieces such as iron wire or steel wire with nylon tube or polyurethane pipe thread at the pipe joint place; But when adopting fastening pieces such as iron wire or steel wire to step up being connected of nylon tube and pipe joint or polyurethane tube and tube joint, installation and removal all need setting tool and extracting tool, owing to carry these instruments inconveniences; Therefore, installation and removal are all inconvenient; In addition, fastening pieces such as iron wire or steel wire damage the joint of nylon tube or polyurethane pipe easily, thereby reduce the working life of pipes such as nylon tube or polyurethane pipe.
The model utility content
The utility model technical problem to be solved is, a kind of cutting ferrule is provided, and said cutting ferrule not only can make being connected firmly of pipe and pipe joint, and installation and removal are more convenient, can guarantee working life of pipe.
The technical solution of the utility model is; A kind of cutting ferrule with following structure is provided; It comprises the cutting ferrule body; One end of said cutting ferrule body outer circumferential face is provided with the annular flange flange that the inner peripheral surface bulge loop shape with pipe joint matches; The said cutting ferrule body outer circumferential face the other end is provided with the pedestal of annular protrusion, and said cutting ferrule body is provided with at least two and extends axially the breach to pedestal from the convex annular acies, and the inside of said cutting ferrule body annular flange flange place end is provided with the plush copper that is used to tighten pipe near the port.After adopting above structure, the utility model cutting ferrule compared with prior art has the following advantages:
Because an end of the cutting ferrule body outer circumferential face of the utility model cutting ferrule is provided with annular flange flange; The cutting ferrule body is provided with from the convex annular acies and extends axially the breach to pedestal; With convex annular acies compression, annular flange flange advances to pipe joint is inner easily, and cutting ferrule convex annular acies surpasses when pulling outward cutting ferrule again behind the pipe joint inner peripheral surface bulge loop; Annular flange flange is opened the bulge loop place that is stuck in pipe joint, and cutting ferrule is difficult for coming off from pipe joint; The said cutting ferrule body outer circumferential face the other end is provided with the pedestal of annular protrusion, and said pedestal provides constraints to the extreme length that cutting ferrule stretches in the pipe joint; Said cutting ferrule body interior is provided with plush copper near the port, and after pipe inserted in the cutting ferrule, the inner plush copper of cutting ferrule played radially snap action to pipe; Make pipe be difficult for being pulled out, the tube drawing period of the day from 11 p.m. to 1 a.m outward, the cutting ferrule annular flange flange receives the squeezing action of pipe joint bulge loop; Because the cutting ferrule body is provided with at least two breach; The back cutting ferrule body that is squeezed inwardly tightens up, the inner plush copper chucking of cutting ferrule tube outer wall, and it is more firm to make that pipe is connected with pipe joint.When needing dismounting, cutting ferrule is moved toward pipe joint is inner, pipe joint is removed the clamping force of cutting ferrule annular flange flange, and the inner plush copper of cutting ferrule reduces pipe active force radially, and pipe can be extracted smoothly; That is to say that installation and removal all do not need setting tool and extracting tool, installation and removal are convenient; And owing to used cutting ferrule, pipe is connected more firm with pipe joint, and fastening pieces such as iron wire or steel wire need not used in the pipe outside, and the pipe coupling place is difficult for being damaged, and can guarantee the working life of pipe.
As preferably, the quantity of said breach is seven, and evenly distributes along cutting ferrule body side face; Seven breach have been divided into eight lobes with the cutting ferrule body; Said eight valve structures connect in base end, during compression, because the existence of breach; Flange end can inwardly be extruded and tighten up, and makes flange end can get into pipe joint smoothly; Simultaneously eight valve structures can be fixed well and tighten pipe from eight directions, make the pipe side face stressed more even, and pipe and cutting ferrule contacting point are not fragile.
As improvement, said pedestal exceeds annular flange flange, easy identification, the convenient installation.
As preferably, said plush copper is a tip, and the chucking pipe is more firm.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4; It comprises cutting ferrule body 1 the utility model cutting ferrule; One end of said cutting ferrule body 1 outer circumferential face is provided with the annular flange flange 2 that inner peripheral surface bulge loop 7 shapes with pipe joint 6 match; The said cutting ferrule body 1 outer circumferential face the other end is provided with the pedestal 3 of annular protrusion; Said cutting ferrule body 1 is provided with at least two and extends axially the breach 5 to pedestal 3 from annular flange flange 2 ends, and the inside of said cutting ferrule body 1 annular flange flange 2 place ends is provided with the plush copper 4 that is used to tighten pipe 8 near the port.
The quantity of said breach 5 is seven, and evenly distributes along cutting ferrule body 1 side face.
Said pedestal 3 exceeds annular flange flange 2.
Said plush copper 4 is a tip.
In the present embodiment, cutting ferrule body 1 has good elasticity, and said plush copper 4 is a tip.
As shown in Figure 3; Seven breach 5 on the cutting ferrule body 1 have been divided into eight valve structures with annular flange flange 2 end faces; Slightly firmly make eight valve structures of cutting ferrule body 1 inwardly tighten up; To pipe joint 6 inner propellings, the inner peripheral surface bulge loop 7 that the annular flange flange 2 of cutting ferrule body 1 is crossed pipe joint 6 fits in the pipe joint 6 with cutting ferrule annular flange flange 2 place ends; Pipe 8 inserts the endoporus of cutting ferrule bodies 1, is stuck in to cutting ferrule body 1 inner plush copper 4 on the outer wall of pipe 8 to stop.
As shown in Figure 4; When receiving external force tube drawing 8; Cutting ferrule annular flange flange 2 receives the squeezing action of the bulge loop 7 of pipe joint 6, because cutting ferrule body 1 upper edge side face is provided with seven breach 5, the back cutting ferrule body 1 that is squeezed inwardly tightens up; The inner plush copper 4 of cutting ferrule sticks into pipe 8 outer walls, makes pipe 8 be connected more firm with pipe joint 6.
