In one preferred embodiment of the utility model, first screwed pipe, attaching nut, central tube and limit casing For integrated steel construction.

In one preferred embodiment of the utility model, second screwed pipe rear end is provided with swivel becket, the rotation Rubber sleeve is covered on ring.

In one preferred embodiment of the utility model, the annular groove is provided with interior spiral shell corresponding with the second screwed pipe Line.

In one preferred embodiment of the utility model, the central tube outer circle is fitted on the inner wall of Bundy tube.

In one preferred embodiment of the utility model, the inner hole of the swivel becket and the outer circle of Bundy tube are corresponding.

In one preferred embodiment of the utility model, the attaching nut is pentagonal configuration.

In one preferred embodiment of the utility model, outer conical surface, the taper are provided with outside the taper gum cover Cutting ferrule inner hole is provided with the internal conical surface oppressed in outer conical surface.

The beneficial effects of the utility model are: a kind of Bandaid pipe fitting that the utility model is pointed out, reinforces the strong of junction Degree avoids deformation when connection, promotes the convenience of installation and maintenance.

Detailed description of the invention

It, below will be to required in embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some realities of the utility model Example is applied, it for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings Obtain other attached drawings, in which:

Fig. 1 is a kind of structural schematic diagram of one preferred embodiment of Bandaid pipe fitting of the utility model.

Specific embodiment

Below by the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described Embodiment is only a part of the embodiment of the utility model, instead of all the embodiments.Based on the implementation in the utility model Example, all other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to The range of the utility model protection.

Referring to Fig. 1, the utility model embodiment includes:

A kind of Bandaid pipe fitting, comprising: the first screwed pipe 1, the second screwed pipe 2, attaching nut 3, central tube 4 and limit sleeve Pipe 5, first screwed pipe 1 and central tube 4 are separately positioned on the two sides of attaching nut 3, and the limit casing 5 is arranged concentrically on The outside of central tube 4,6 end of Bundy tube extend between the central tube 4 and limit casing 5, on 5 inner wall of limit casing It is provided with annular groove 7, the hollow sebific duct 8 of annular, the taper gum cover 9 being set in Bundy tube outer circle are provided in the annular groove 7 With taper cutting ferrule 10, there are two the hollow settings of sebific duct 8 of annular, is provided with taper between described two hollow sebific ducts 8 of annular Gum cover 9 and taper cutting ferrule 10, the taper gum cover 9 and taper cutting ferrule 10 are correspondingly arranged, and 2 front end of the second screwed pipe extends to The hollow sebific duct 8 of annular, taper gum cover 9 and taper cutting ferrule 10 are squeezed in annular groove 7.

Second screwed pipe, 2 rear end is provided with swivel becket 11, covers rubber sleeve on the swivel becket 11, facilitates rotation, It is easy to operate.

Second screwed pipe, 2 front end extends in annular groove 7, squeezes hollow sebific duct 8, the pressure that when extruding generates Power squeezes taper cutting ferrule 10, and taper cutting ferrule 10 is squeezed to taper gum cover 9, realizes the fastening to 6 outer circle of Bundy tube.

Outer conical surface is provided with outside the taper gum cover 9,10 inner hole of taper cutting ferrule is provided with compressing in outer cone Internal conical surface on face, the extruding of the external circular conical surface of internal conical surface avoid Bundy tube so that 9 Bundy tube 6 of taper gum cover fastens 6 loosening.

In conclusion a kind of Bandaid pipe fitting that the utility model is pointed out, reinforces the intensity of junction, when avoiding connecting Deformation promotes the convenience of installation and maintenance.

The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all Using equivalent structure or equivalent flow shift made by the utility model description, it is applied directly or indirectly in other phases The technical field of pass, is also included in the patent protection scope of the utility model.
