Description
Technical field
The utility model relates to a kind of hose coupling, relates to a kind of 90 ° of fastening-pressing type hose couplings 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.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 that a kind of nut outer side wall corner angle are difficult for being worn, good sealing effect and the 90 ° fastening-pressing type hose couplings of nut axial limiting on tubular body.
Technical solution of the present utility model is, a kind of 90 ° of fastening-pressing type hose couplings with following structure are provided, it comprises the joint body that is provided with through hole, described joint body is provided with flexible pipe butt end and threaded pipe butt end, described threaded pipe butt end axial limiting is sheathed with nut, and the formed angle of central shaft of the central shaft of described threaded pipe butt end and flexible pipe butt end is 90 °; Described nut is a pentagon nut; The port wall of the through hole of described threaded pipe butt end is provided with conical surface, and two the symmetrical formed angles in sideline of axis with the through hole of threaded pipe butt end on the described conical surface are 55 °～65 °, and described angle is positioned at outside the joint body; The outer wall of described threaded pipe butt end is provided with radially scrobicular ring, but the inwall of described nut nearer relatively end from the flexible pipe butt end radially inwardly protrudes out the formation axial limiting and can be engaged in bulge loop in the described scrobicular ring with rotating in a circumferential direction.
After adopting above structure, 90 ° of fastening-pressing type hose couplings of the utility model compared with prior art have the following advantages:
Because the nut of 90 ° of fastening-pressing type hose couplings 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 outside the 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 scrobicular ring, and the inwall of nut nearer end from the flexible pipe butt end is provided with bulge loop, but described bulge loop axial limiting and can being engaged in the scrobicular ring with rotating in a circumferential direction, this kind design, simple in structure, realize easily.
As a kind of improvement of the present utility model, described angle 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 the end of link being set in the tapped hole of nut, be not easy to run into the tapped hole hole wall, can conveniently install.
