As a kind of optimal technical scheme of the utility model, the swivel nut is close to the circular cone on the inside of one end of tube body end Face is identical far from the lateral surface circular conical surface taper of its end as on tube body.
As a kind of optimal technical scheme of the utility model, one end lateral surface of the swivel nut close to tube body end is arranged Screw thread and connecting tube outer end medial surface setting screw thread be 55 degree of sealing pipe screw threads.
As a kind of optimal technical scheme of the utility model, first sealing ring is that rubber material is made, second Sealing ring is made of metal material.
As a kind of optimal technical scheme of the utility model, the swivel nut on one end lateral surface of tube body end face far from pressing It is formed with annular knurl line.
Compared with prior art, the utility model has the beneficial effects that this connecting pipe fitting of thin wall metal pipe, connection construction behaviour Make extremely simplicity, is easy to implement, rigid seal is combined with flexible sealing, quadruple seal approach, good seal performance, reliability Height, can also repeated disassembled and assembled, the performance repeatedly used can guarantee higher consistency, and the annular knurl line suppressed on swivel nut can increase Friction, can effectively prevent skidding during installation, and practicability is high.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 tube body, 2 connecting tubes, 3 swivel nuts, 4 first sealing rings, 5 second sealing rings, 6 swivel nuts, 7 annular knurl lines.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of connecting pipe fitting of thin wall metal pipe, including tube body 1, connecting tube 2 and swivel nut 3, swivel nut 3 are set on tube body 1, and one end of connecting tube 2 is set in the end of tube body 1, connecting tube 2 The other end is set in the end of another tube body 1, and the end of tube body 1 is the protuberance of cone, and swivel nut 3 is close to 1 end of tube body It is circular conical surface on the inside of one end, swivel nut 3 is outer far from its end close on the circular conical surface and tube body 1 on the inside of one end of 1 end of tube body Side circular conical surface taper is identical, is in close contact to form A with the circular conical surface on tube body 1 turning the circular conical surface in 3 rear thread sleeve 3 of swivel nut Locate seal point, one end lateral surface of swivel nut 3 close to 1 end of tube body is provided with screw thread, outside the one end of swivel nut 3 far from 1 end of tube body Side is suppressed with annular knurl line 7, and annular knurl line 7 can increase friction, can effectively prevent skidding during installation, and practicability is high, outside connecting tube 2 End medial surface setting also has screw thread, and swivel nut 3 is close in the screw thread and 2 outer end of connecting tube of one end lateral surface setting of 1 end of tube body The screw thread of side setting is 55 degree of sealing pipe screw threads, and swivel nut 3 forms close at B after being threadedly coupled with connecting tube 2 by 55 degree of sealings Seal point, the middle part of connecting tube 2 are placed with the second sealing ring 5, and the end face of tube body 1 is in contact with the end face of the second sealing ring 5, are twisting After movable snail sleeve 3, under 3 impetus of swivel nut, the end face of two tube bodies 1 is in close contact with the both ends of the surface of the second sealing ring 5 respectively, Seal point at D is formed, connecting tube 2 is internally provided with stepped hole, the first sealing ring 4, the first sealing ring 4 are placed at stepped hole With tube body 1 close to the taper face contact of its end, tube body 1 forms seal point at C after suppressing the first sealing ring 4 of rubber material, First sealing ring 4 is that rubber material is made, and the second sealing ring 5 is made of metal material.
