Abstract
The utility model discloses a swaged hose joint, comprising a joint body (1) which is provided with an axial through hole (1.1). The joint body (1) is provided with a hose abutting end (1.2) and a threaded pipe abutting end (1.3); an outer thread (2) is arranged on the outer wall of the threaded pipe abutting end (1.3), and a screw cap (4) is fixed on the outer wall of the threaded pipe abutting end (1.3) and positioned at the inner side of the axial direction of the outer thread (2), and the screw cap (4) is a pentagonal screw cap; the port wall of the through hole (1.1) of the threaded pipe abutting end (1.3) is provided with a conical surface (3), an included angle (a) formed by two side lines symmetrical relative to the axial line of the through hole (3) on the conical surface (3) is in the range of 55-65 degrees, and the included angle is positioned in the joint body (1). The arris of the outer side wall of the screw cap of the swaged hose joint is difficult to abrade, and the sealing effect is good.
Description
Technical field
The utility model relates to a kind of hose coupling, relates to a kind of fastening-pressing type hose coupling or rather.
Background technique
The fastening-pressing type hose coupling is used comparatively extensive, generally is used for transferring oil, water or gas.Present fastening-pressing type hose coupling comprises the joint body that is provided with axial hole, and an end of described joint body is the flexible pipe butt end that is used to connect flexible pipe, and the other end of described joint body is the threaded pipe butt end that is used to connect the threaded pipe on the equipment.The outer wall of described threaded pipe butt end is provided with outside thread, also is fixed with nut and described nut on the outer wall of described threaded pipe butt end and is positioned at externally threaded axial inboard.The nut of prior art fastening-pressing type hose coupling is generally hexagon nut, and the external frame limit number of hexagon nut is more, near circular, can be when turning owing to the excessive corner angle wearing and tearing that make the hexagon nut outer side wall of exerting oneself with spanner, spanner is skidded, thereby can not tighten, it is unreliable to cause the threaded pipe butt end to be connected with threaded pipe.In addition, hose coupling in use, the threaded pipe butt end is connected with the threaded pipe that is provided with internal thread, consider the sealing between threaded pipe butt end and the threaded pipe, usually between the end face that both connect, place a seal ring, and the end face of the threaded pipe butt end of prior art and the area of contact between the seal ring are less, thereby influence sealing effect.
The model utility content
The technical problems to be solved in the utility model is, provides a kind of nut outer side wall corner angle to be difficult for being worn and the fastening-pressing type hose coupling of good sealing effect.
Technical solution of the present utility model is, a kind of fastening-pressing type hose coupling with following structure is provided, it comprises the joint body that is provided with axial hole, described joint body is provided with flexible pipe butt end and threaded pipe butt end, the outer wall of described threaded pipe butt end is provided with outside thread, also be fixed with nut and described nut on the outer wall of described threaded pipe butt end and be positioned at externally threaded axial inboard, described nut is five jiaos of nuts; The port wall of the through hole of described threaded pipe butt end is provided with conical surface, is 55 °～65 ° with two symmetrical formed angles in sideline of through-bore axis on the described conical surface, and described angle is positioned at joint body.
After adopting above structure, the utility model fastening-pressing type hose coupling compared with prior art has the following advantages:
Because the nut of fastening-pressing type hose coupling of the present utility model is five jiaos of nuts, its external frame is a pentagon, the limit number is less, differ far away with circle, excessive even exert oneself when turning with spanner also can be with the wearing and tearing of the corner angle of five jiaos of nut outer side walls, thereby can tighten, make that connection is more reliable between hose coupling and the connected piece.Again because the port wall of the through hole of described threaded pipe butt end is provided with conical surface, it is 55 °～65 ° with two symmetrical formed angles in sideline of through-bore axis on the described conical surface, described angle is positioned at joint body, can increase the area of contact between threaded pipe butt end and the seal ring, make that the sealing effect of seal ring is better.
As a kind of improvement of the present utility model, described angle is 60 °.It is optimum implementation that described angle is 60 °.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Figure 1 and Figure 2, the utility model fastening-pressing type hose coupling comprises the joint body 1 that is provided with axial hole 1.1, and described joint body 1 is provided with flexible pipe butt end 1.2 and threaded pipe butt end 1.3.The outer wall of described threaded pipe butt end 1.3 is provided with outside thread 2, also is fixed with the axial inboard that nut 4 and this nut 4 are positioned at outside thread 2 on the outer wall of described threaded pipe butt end 1.3, and described nut 4 can be one-body molded with joint body 1.Described nut 4 is a pentagon.The port wall of the through hole 1.1 of described threaded pipe butt end 1.3 is provided with conical surface 3, it is 55 °～65 ° with the symmetrical formed angle a in two sidelines of through hole 1.1 axis on the described conical surface 3, described angle a is positioned at joint body 1, in this specific embodiment, described angle a is 60 °.The outer wall of described flexible pipe butt end 1.2 is provided with a plurality of ring-types awl teeth 5, also is provided with on the outer wall of described flexible pipe butt end 1.2 to be used to tighten the axial inboard that the snap ring 6 that is connected hose end and this snap ring 6 are positioned at described awl tooth 5.
During use, earlier between the end face of the threaded pipe butt end 1.3 of the end face of threaded pipe and hose coupling, place seal ring, by spanner threaded pipe butt end 1.3 and threaded pipe are tightened then, after tighten with threaded pipe threaded pipe butt end 1.3, seal ring just is stuck between the end face of the end face of threaded pipe and threaded pipe butt end 1.3, and the outer wall of seal ring tightly touch the conical surface 3 of threaded pipe butt end 1.3.
