The utility model discloses a fastening-pressing type hose joint with a nut, which comprises a joint body (1), wherein the nut which axially limits the joint body (1) and circumferentially rotates is arranged at one end of the join body (1), and a bamboo joint (2) connected with a hose is arranged at the other end of the joint body (1); the nut is a pentagonal nut (3), and the outer surface of one end of the joint body (1) close to the pentagonal nut (3) is a conical surface (4); the conical surface (4) extends to form a cone angle a of 36 degrees to 38 degrees, and the cone angle a is positioned outside the joint body (1); an annular outer convex block (5) is arranged on the outer surface of one end of the joint body (1) close to the pentagonal nut (3), and an annular inner convex block (6) capable of axially leaning against the annular outer convex block (5) is arranged on the inner surface of one end of the pentagonal nut (3); and the annular inner convex block (6) axially limits the annular outer convex block (5) and circumferentially rotates. The nut of the hose joint and a wrench are not easy to produce relative sliding, so the hose joint is not easy to leak.

Description

A kind of band nut fastening-pressing type hose coupling
Technical field
The utility model relates to a kind of hose coupling, specifically is a kind of band nut fastening-pressing type hose coupling.
Background technique
Band nut fastening-pressing type hose coupling on the market is mainly used in the conveying of oil, gas, water etc. at present, it comprises the joint body of hollow, one end of described joint body be provided with one with joint body axial limiting and the nut that circumferentially rotates, described nut is used for being connected with threaded pipe; The other end of described joint body is provided with the ring joint that is connected with flexible pipe, and described nut is a hexagon nut.There is following defective in the band nut fastening-pressing type hose coupling of said structure in the using process of reality:
1, because the band nut fastening-pressing type hose coupling of prior art uses is hexagon nut, the hexagonal configuration of this nut approaches circle, therefore in the process of using spanner to turn, easily produce slide relative between this hexagon nut and the spanner, thereby cause joint to damage.
2, only rely on screw thread to seal between the band nut fastening-pressing type hose coupling of prior art and the threaded pipe, its sealing is relatively poor, therefore this hose coupling is easy to produce in the using process of reality and leaks, thereby makes the functional reliability of prior art hose coupling reduce.
The model utility content
The technical problems to be solved in the utility model is, overcomes the defective of above prior art, and the band nut fastening-pressing type hose coupling that is difficult for producing slide relative between a kind of nut and the spanner and is difficult for taking place leaking is provided.
The technical solution of the utility model is, a kind of band nut fastening-pressing type hose coupling is provided, the joint body that comprises hollow, one end of described joint body be provided with one with joint body axial limiting and the nut that circumferentially rotates, the other end of described joint body is provided with the ring joint that is connected with flexible pipe, and described nut is five jiaos of nuts; Described joint body is a conical surface near the outer surface of five jiaos of nut one ends, and it is 36 °~38 ° that described conical surface extends formed cone angle a, and described cone angle a is positioned at outside the joint body; Described joint body is provided with an annular outer piece near the outer surface of five jiaos of nut one ends, the internal surface of described five jiaos of nut one ends is provided with projection in the annular that axially offsets with the annular outer piece, projection and annular outer piece axial limiting and circumferentially rotation in the described annular.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, the nut in the utility model is five jiaos of nuts, this nut is compared with the hexagon nut of prior art, its shape is kept off in circle, therefore in the process of using spanner to turn, be difficult for producing slide relative between these five jiaos of nuts and the spanner, make this joint not fragile, thereby guaranteed the working life of this hose coupling.In addition, described joint body is provided with an annular outer piece near the outer surface of five jiaos of nut one ends, the internal surface of described five jiaos of nut one ends is provided with projection in the annular that axially offsets with the annular outer piece, projection and annular outer piece axial limiting and circumferentially rotation in the described annular.The utility model hose coupling utilize the annular outer piece and the annular in projection come five jiaos of nuts are carried out spacing, its good limit effect.
2, the joint body of the utility model hose coupling is a conical surface near the outer surface of outside thread one end, it is 36 °~38 ° that conical surface extends formed cone angle a, cone angle a is positioned at outside the joint body, this joint not only can rely on screw thread to seal, and can on threaded pipe, process the conical surface that matches with this conical surface, utilize two cooperatively interacting of the conical surface and seal its better tightness.Therefore this joint is difficult for producing in the using process of reality leaking, thereby has guaranteed the functional reliability of the utility model hose coupling.
As improvement, described cone angle a is 37 °, and the sealing effect of two conical surfaces that utilizes into this cone angle is better, its more difficult leakage.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Figure 3, a kind of band nut of the utility model fastening-pressing type hose coupling comprises the joint body 1 of hollow, and in the present embodiment, joint body 1 is the straight tube-like body.
One end of described joint body 1 be provided with one with joint body 1 axial limiting and the nut that circumferentially rotates, the other end of described joint body 1 is provided with the ring joint 2 that is connected with flexible pipe, in the present embodiment, described joint body 1 is provided with an annular outer piece 5 near the outer surface of five jiaos of nut 3 one ends, the internal surface of described five jiaos of nut 3 one ends is provided with projection 6 in the annular that axially offsets with annular outer piece 5, projection 6 and annular outer piece 5 axial limitings and circumferential rotation the in the described annular.Such five jiaos of nuts 3 carry out spacing with joint body 1.The other end at joint body 1 processes ring joint 2, and ring joint 2 is provided with a draw-in groove 2.1, and this draw-in groove 2.1 is used for and is clasped with the fastening flexible pipe.
