Abstract
The utility model discloses a pigeonhole type hose joint, comprising a hollow joint main body (1), an external thread (2) arranged on one end of the joint main body (1) and connected with a threaded pipe, a bamboo node joint (3) arranged on another end of the joint main body (1) and connected with the hose and a pentagonal screw cap (4) fixed on the axial inner side of one end of the joint main body (1) near to the external thread (2), wherein the inner surface of one end of the joint main body (1) near to the external thread (2) is a cone shaped surface (5), the cone shaped surface (5) extends to form a cone angle a of 36-38 degree and the cone angle a is arranged in the joint main body (1). The relative slip and leak can not be easily generated between the screw cap of the hose joint and a wrench.
Description
Technical field
The utility model relates to a kind of hose coupling, specifically is a kind of fastening-pressing type hose coupling.
Background technique
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 is provided with the outside thread that is 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 joint body is provided with hexagon nut near the axial inboard of outside thread one end.There is following defective in the fastening-pressing type hose coupling of said structure in the using process of reality:
1, because the 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 produces slide relative between this hexagon nut and the spanner, thereby causes joint to damage.
2, only rely on screw thread to seal between the 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 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 fastening-pressing type hose coupling is provided, the joint body that comprises hollow, one end of described joint body is provided with the outside thread that is connected with threaded pipe, the other end of described joint body is provided with the ring joint that is connected with flexible pipe, described joint body is fixed with nut near the axial inboard of outside thread one end, and described nut is five jiaos of nuts; Described joint body is a conical surface near the internal surface of outside thread one end, and it is 36 °～38 ° that described conical surface extends formed cone angle a, and described cone angle a is positioned at joint body.
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.
2, the joint body of the utility model hose coupling is a conical surface near the internal surface of outside thread one end, it is 36 °～38 ° that conical surface extends formed cone angle a, cone angle a is positioned at 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 fastening-pressing type hose coupling of the utility model 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 is provided with the outside thread 2 that is connected with threaded pipe, the other end of described joint body 1 is provided with the ring joint 3 that is connected with flexible pipe, described joint body 1 is fixed with nut near the axial inboard of outside thread 2 one ends, in the present embodiment, outside thread 2 processes for the end at joint body 1, the other end at joint body 1 processes ring joint 3, and ring joint 3 is provided with a draw-in groove 3.1, and this draw-in groove 3.1 is used for and is clasped with the fastening flexible pipe; Described joint body 1 is fixed with nut near the axial inboard of outside thread 2 one ends, and this nut is the right side of outside thread 2 in Fig. 1, and this nut is welded on the joint body 1.
Described nut is five jiaos of nuts 4, these five jiaos of nuts 4 be shaped as positive pentagon; Described joint body 1 is a conical surface 5 near the internal surface of outside thread 2 one ends, it is 36 °～38 ° that described conical surface 5 extends formed cone angle a, described cone angle a is positioned at joint body 1, and wherein, cone angle a is that the symmetrical bus of two of conical surface 5 extends formed.
Described cone angle a is 37 °.
Below only be described, but can not be interpreted as it is restriction claim with regard to most preferred embodiment of the present utility model.The utility model is not limited only to above embodiment, and its concrete structure allows variation.In every case the various variations of being done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
