In order to solve the problems of the technologies described above, ductile iron pipe anchoring interface of the present invention comprises bellmouth, to be inserted in bellmouth and outer surface is fixed with the socket of ring-shaped fixing rings, and be sleeved on differential that bellmouth and socket link together on socket, the internal surface of described bellmouth is provided with the sealed groove of the annular being embedded with seal ring, outer surface is fixed with the bulge loop of annular, the internal surface of described differential is the cone-shaped inner hole of annular, the annular groove matched with bulge loop is provided with on the right side of cone-shaped inner hole, described retaining ring is positioned at cone-shaped inner hole and the diameter of outer surface is greater than diameter on the left of cone-shaped inner hole.
In order to increase the anticreep intensity of interface, be also provided with the baffle ring of movable set on socket in described cone-shaped inner hole, baffle ring is positioned at the left side of retaining ring.
In order to increase interface anticreep intensity further, the outer surface of described baffle ring is the conical surface identical with cone-shaped inner hole bevel angle.
In order to further increase the anticreep intensity of interface, the angle on described cone-shaped inner hole inclined-plane is 15-45 degree.
The conveniently manufacturing of interface, described bulge loop is cylindrical.
The conveniently installation of differential, described differential is made up of identical two-part.
In order to meet the requirement of interface to deflection angle, the diameter 5-10 millimeter larger than the external diameter of socket of described cone-shaped inner hole left end.
The invention has the beneficial effects as follows: the present invention by arranging annular groove and cone-shaped inner hole on differential, and socket and bellmouth link together by the intensity taking full advantage of differential itself, do not need the paving of other annexes to help, structure is simple, easy for installation; Meanwhile, this structure can bear larger pull-out force, and anticreep ability is strong.

Specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.
Embodiment one
As Fig. 1 shows a kind of mode of execution of ductile iron pipe anchoring interface of the present invention.As shown in Figure 1, ductile iron pipe anchoring interface of the present invention comprises bellmouth 2, to be inserted in bellmouth 2 and outer surface is fixed with the socket 1 of ring-shaped fixing rings 8 and is sleeved on differential 3 that bellmouth 2 and socket 1 link together on socket 1.As shown in Figure 1, the internal surface of bellmouth 2 is provided with the sealed groove 11 of the annular being embedded with seal ring 10, outer surface is fixed with the columniform bulge loop 4 of annular, here it should be noted that the shape optimal selection of bulge loop 4 is cylindrical, the casting processing of the more convenient bellmouth of columniform projection, but be not only confined to this kind of shape, and every shape of axial pull-out force that can stop is all passable, as eave tile shape etc., those skilled in the art can freely convert as required.As described in Figure 1, the internal surface of differential 3 is the cone-shaped inner hole 5 of annular, is provided with the annular groove 6 matched with bulge loop 4 on the right side of cone-shaped inner hole 5, and described retaining ring 8 is positioned at cone-shaped inner hole 5 and the diameter of outer surface is greater than diameter on the left of cone-shaped inner hole 5.When ductile iron pipe waterline inside is by hydraulic pressure effect or other External Force Actings, the socket of ductile iron pipe can from the inner outwards pull-off of bellmouth, because differential is provided with annular groove and cone-shaped inner hole, differential by annular groove and annular protrusion coordinate and retaining ring and cone-shaped inner hole interact socket and firm the linking together of bellmouth, ductile iron pipe is effectively prevented mutually to throw off, do not need the auxiliary connection of other annexes, structure is simple, easy for installation; The strength ratio of differential own is comparatively large simultaneously, and the pull-out force of axis can be decomposed, therefore, it is possible to bear larger pull-out force, anticreep ability is stronger.
Embodiment two
In order to increase the anticreep intensity of interface, reach better anticreep effect.As shown in Figure 1, the basis of embodiment one is provided with the baffle ring 9 of movable set on socket 1, and baffle ring 9 is positioned at the left side of retaining ring 8.As shown in Figure 1, baffle ring 9 is positioned at cone-shaped inner hole 5, that is baffle ring 9 is positioned at the space that cone-shaped inner hole 5 is formed with retaining ring 8, and the while that this structure meaning the minimum diameter that the outer surface diameter of baffle ring 9 is greater than on the left of cone-shaped inner hole 5, inner surface diameter is less than the outer surface diameter of retaining ring 8.In order to increase the anticreep intensity of interface further, as shown in Figure 1, be set to by the outer surface of baffle ring 9 and cone-shaped inner hole 5 bevel angle same conical face 12, bevel angle is all 30 degree, and this angle is optimum angle.The anticreep intensity of interface is effectively increased by increasing movable baffle ring 9.
Easy for installation in order to differential, as shown in Figure 1, described differential 3 is made up of identical two-part, and identical two-part are fixedly connected with by the connecting plate 7 being vertically fixed on differential outer surface.
In order to meet the needs of interface to deflection angle, larger than the external diameter of socket 10 millimeters of the diameter of described cone-shaped inner hole left end, this numerical value is optimum value.
It should be noted that example two is most preferred mode of executions of the present invention, be not restriction the present invention being made to other form, any those skilled in the art of belonging to may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent implementations of equivalent variations.But every do not depart from the prerequisite of the technology of the present invention principle under, any simple modification, equivalent variations and the remodeling done above mode of execution according to technical spirit of the present invention, all should fall into scope of patent protection of the present invention.
