Description
Technical field
The utility model relates to a kind of hose coupling, relates to a kind of hose coupling of fastening-pressing type or rather.
Background technique
The hose coupling of fastening-pressing type is used comparatively extensive, generally is used for transferring oil, water or gas.The hose coupling of present fastening-pressing type 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.But described threaded pipe butt end axial limiting is sheathed with and is used for and is provided with the nut that externally threaded threaded pipe is connected, the nut of the hose coupling of the fastening-pressing type of prior art 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 tapped hole butt end to be connected with threaded pipe.In addition, hose coupling in use, nut on the threaded pipe butt end connects so that the end face of the end face of threaded pipe butt end and threaded pipe is close to mutually with threaded pipe, 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 hose coupling of the fastening-pressing type of good sealing effect.
Technical solution of the present utility model is, a kind of hose coupling with fastening-pressing type of following structure is provided, it comprises the joint body that is provided with axial hole, and described joint body is provided with flexible pipe butt end and threaded pipe butt end, and described nut is a pentagon nut; 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 outside the joint body; The outer wall of described threaded pipe butt end is provided with the back-up ring that radially outward protrudes out, but the inwall of described nut nearer end from the flexible pipe butt end radially inwardly protrudes out the bulge loop of formation axial limiting on described back-up ring.
After adopting above structure, the hose coupling of the utility model fastening-pressing type compared with prior art has the following advantages:
Because the nut of fastening-pressing type hose coupling of the present utility model is a pentagon nut, 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 pentagon nut outer side wall, 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.In addition, the outer wall of threaded pipe butt end is provided with back-up ring, and the inwall of nut nearer end from the flexible pipe butt end is provided with bulge loop, and back-up ring can carry out axial limiting to bulge loop, and this kind design is simple in structure, realizes easily.
As a kind of improvement of the present utility model, described angle (a) is 60 °.It is optimum implementation that described angle is 60 °.
As another kind of improvement the of the present utility model, described nut is provided with horn mouth away from an end that is provided with bulge loop.Like this, when arriving threaded tube in the tapped hole of screw thread, be not easy to run into the tapped hole hole wall, can conveniently install.
