Abstract

The utility model discloses a pigeonhole type hose joint, comprising a joint main body with an axial through hole, wherein the joint main body is provided with a hose abutting end and a screwed pipe abutting end, the screwed pipe abutting end axially fitted with a pentagonal nut at a position-limited state; a cone shaped surface is arranged on the port wall of the through hole of the screwed pipe abutting end, the included angle between two mutually symmetrical edges on the cone shaped surface by the through hole axle is 55-65 degree and arranged outside the joint main body; a radial concave ring is arranged on the outer wall of the abutting end of the screwed pipe, the inner wall of one end of the nut relative near to the hose abutting end inwards projects to form a convex ring capable of be axially position-limitedly and circumferentially rotataly cooperated with the concave ring. The edge angle on the outer side wall of the nut of the hose joint is not easily worn and the sealing effect is good.

Description

A kind of fastening-pressing type hose coupling
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.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 nut outer side wall corner angle to be difficult for being worn and a kind of fastening-pressing type hose coupling of good sealing effect.
Technical solution of the present utility model is, a kind of 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, described threaded pipe butt end axial limiting is sheathed with nut, 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 radially scrobicular ring, but the inwall of described nut nearer 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, a kind of fastening-pressing type hose coupling of the utility model compared with prior art has the following advantages:
Because the nut of a kind of fastening-pressing type hose coupling of the 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 arriving threaded tube in the tapped hole of screw thread, be not easy to run into the tapped hole hole wall, can conveniently install.

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, a kind of fastening-pressing type hose coupling of the utility model 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.Described threaded pipe is sheathed with nut 2 outside the butt end, and described nut 2 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 outside the joint body 1, in this specific embodiment, described angle a is 60 °.The outer wall of described threaded pipe butt end 1.3 is provided with radially scrobicular ring 1.3.1, but the inwall of described nut 2 1.2 nearer ends from the flexible pipe butt end radially inwardly protrudes out the formation axial limiting and can be engaged in bulge loop 2.1 in the described scrobicular ring 1.3.1 with rotating in a circumferential direction.The outer wall of described flexible pipe butt end 1.2 is provided with a plurality of ring-types awl teeth 4, 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 5 that is connected hose end and this snap ring 5 are positioned at described awl tooth 4.
During use, earlier between the end face of the end face of threaded pipe and threaded pipe butt end 1.3, place seal ring, by spanner nut 2 and threaded pipe are tightened then, after nut and 2 threaded pipes are tightened, seal ring just is stuck between the end face of threaded pipe end face and threaded pipe butt end 1.3, and the outer wall of seal ring will touch the conical surface 3 of threaded pipe butt end 1.3 tightly.
