Abstract
The utility model discloses a connecting pipe comprising a pipe connector, a pipe, a seal ring and an outer screw cap. The end of the pipe the pipe is radially upheaved to form into a circle of convex ring, the back of which is provided with the outer screw cap; the inner wall of the pipe connector is provided with a shoulder hole corresponding to the convex ring, and the outer wall of the pipe connector is provided with an outer screw corresponding to the outer screw cap; the front of the convex ring of the pipe is provided with the seal ring inserted into the pipe connector, and the outer screw cap is screwed down and connected with the pipe connector. With the connection mode, the end of the pipe need not to be harmfully processed, the thickness of the wall of the pipe is greatly decreased, plenty of metal materials is saved, the utility model has the advantages of easy and firm connection as well as good seal.
Description
Technical field
The utility model relates to the field of liquid, gas delivery tubular union, the metal pipe element that particularly is tightly connected.
Background technique
Traditional metal tube Placement, be connected firmly for reaching, closely, non-leakage purpose, the ways that adopt damage tubing end more, promptly open hinge worm tooth or open channels at pipe end, so that be connected with the internal thread or the groove of pipe joint, because worm tooth and groove have certain height or degree of depth requirement, the wall thickness of tubing just need be reserved as the surplus of machining screw tooth or groove when producing tubing, cause the whole wall thickness of tubing to be much higher than the size that real fluid pressure sets, unreasonable just because of linkage structure, cause the metallic material of tubing to be wasted in a large number, cost of production is higher.
The model utility content
The purpose of this utility model is to propose a kind ofly can wholely to reduce the metal pipe wall thickness, and is easy to connect, and is connected firmly, the connection pipe fitting of good airproof performance.
The technical solution of the utility model is: a kind of connection pipe fitting, include pipe joint, body, seal ring and exterior nut cap, and the end protuberance of body forms a circle bulge loop, and exterior nut cap is placed in the bulge loop back; The inwall of pipe joint has the shoulder hole corresponding with bulge loop, and the outer wall of pipe joint then has the outside thread corresponding with exterior nut cap, and in the seal ring insertion tube joint, exterior nut cap screws with pipe joint and is connected on the bulge loop protheca of body.Further, a bulge loop one side of body and seal ring, pipe joint shoulder hole are closely withheld; Closely withhold on another side of bulge loop and the interior oblique rank of exterior nut cap.
Such linkage structure, body itself need not carry out abrasive cutting, need only can be connected with pipe seal by diffusion formation bulge loop, the wall thickness of body can directly be set as required, need not reserve the cutting surplus, the metal consumptive material of body is greatly reduced, and cost of production greatly reduces.But also having pipe end compression and tensile strength height, connection is simple, firm, advantages such as good airproof performance.
Description of drawings
Fig. 1 is a linkage structure schematic representation of the present utility model;
Fig. 2 is a partition schematic representation of the present utility model.
Embodiment
Referring to Fig. 1 and Fig. 2, present embodiment mainly is made of stainless steel body 1, pipe joint 2, seal ring 3 and exterior nut cap 4.The end of body 1 forms a circle bulge loop 11 through the diffusion protuberance.The inwall of pipe joint 2 has the shoulder hole 21 corresponding with seal ring 3 and body bulge loop 11; Its outer wall has the outside thread 22 corresponding with exterior nut cap 4.The inwall of exterior nut cap 4 bottom is formed with the interior oblique rank 41 corresponding with body bulge loop 11.Seal ring 3 is placed in the front of body bulge loop 11; 4 back that are set in body bulge loop 11 of exterior nut cap.When being linked and packed, in the body 1 end insertion tube joint 2, the outside thread 22 of exterior nut cap 4 spinning in pipe joints 2, when screwing, bulge loop 11 is subjected to the pressure that links closely on oblique rank 41 in the exterior nut cap 4, just in time compresses the shoulder hole 21 of seal ring 3 and pipe joint 2, forms first layer fastening-pressing type sealing configuration; Shoulder hole 21 forms second layer fastening-pressing type sealing configuration with the interior oblique rank 41 of bulge loop 11, exterior nut cap 4; Pipe joint outside thread 22 is connected to form three-layer sealed structure with exterior nut cap 4 screw-internal thread fit.
Certainly, only enumerate a kind of preferred implementation here, the technical program can be done other and be equal to or variation roughly the same, repeat no more here, but they all should belong to the protection domain of this patent.
Claims (2)
1, a kind of connection pipe fitting includes pipe joint, body, seal ring and exterior nut cap, it is characterized in that: the end protuberance of body forms a circle bulge loop, and exterior nut cap is placed in the bulge loop back; The inwall of pipe joint has the shoulder hole corresponding with bulge loop, and the outer wall of pipe joint then has the outside thread corresponding with exterior nut cap, and in the seal ring insertion tube joint, exterior nut cap screws with pipe joint and is connected on the bulge loop protheca of body.
2, connection pipe fitting according to claim 1 is characterized in that a bulge loop one side of body and seal ring, pipe joint shoulder hole closely withhold; Closely withhold on another side of bulge loop and the interior oblique rank of exterior nut cap.
