In order to solve the above technical problems, the technical solution of the utility model is：A kind of circlip type stainless steel pipes company is provided Binding structure, it is characterised in that including pipe fitting, the pipe fitting includes the grafting tube body at both ends and the connection pipe body at middle part, and two Grafting tube body is separately positioned on the both ends of connection pipe body；The card in the inner wall junction of grafting tube body and connection pipe body setting annular Platform is successively set between chuck and the outer chuck of annular from inside to outside in the outer chuck of overhanging end setting annular of grafting tube body, annular Seal assembly, washer and circlip are set, stainless steel pipe can sequentially pass through annular outer chuck, circlip, washer from outside to inside, penetrate And terminate in seal assembly.

Preferably, the circlip is hole card spring；The hole card spring include section in ">" shape cyclic annular revolution, Three or more latches are arranged in the inner circumferential of cyclic annular revolution；The annular diameters that latch is enclosed are less than stainless steel tube to be connected Outer diameter.

Preferably, the seal assembly includes radial seal "O"-ring and axial seal "O"-ring from outside to inside, described Stainless steel pipe passes through radial seal "O"-ring and terminates in axial seal "O"-ring, and the axial seal "O"-ring is adjacent to ring Chuck in shape.

Preferably, the seal assembly further includes sealing shroud, the sealing shroud be section in " the cyclic annular revolution of " " shape, The radial seal "O"-ring is arranged in the inside of sealing shroud and is wrapped by sealing shroud, and the axial seal "O"-ring is set It sets in sealing shroud and annular between chuck.

Compared with prior art, the utility model has the beneficial effects that：

The utility model, it is easy to operate, it is easy to connect, without being equipped with expensive specific purpose tool and professional operator, Connection stainless steel tube can be fast docked, is firmly installed, and there is excellent sealing performance.

Specific embodiment

The utility model is described in further detail with specific embodiment with reference to the accompanying drawing.

As shown in Figure 1, circlip type stainless steel tube pipeline connecting structure described in the utility model, including pipe fitting, the pipe Connector includes the grafting tube body at both ends and the connection pipe body at middle part, and two grafting tube bodies are separately positioned on the both ends of connection pipe body； Annular wild card is arranged in the overhanging end of grafting tube body in the chuck in the inner wall junction of grafting tube body and connection pipe body setting annular Platform sets gradually seal assembly, washer and circlip, stainless steel pipe energy between chuck and the outer chuck of annular in annular from inside to outside It is enough to sequentially pass through annular outer chuck, circlip, washer from outside to inside, it penetrates and terminates in seal assembly.

As shown in Fig. 2, the circlip is hole card spring；The hole card spring include section in ">" shape cyclic annular revolution, In the inner circumferential of cyclic annular revolution, three or more latches are set；The annular diameters that latch is enclosed are less than stainless steel tube to be connected Outer diameter.

The seal assembly includes radial seal "O"-ring and axial seal "O"-ring, the stainless steel tube from outside to inside Part passes through radial seal "O"-ring and terminates in axial seal "O"-ring, and the axial seal "O"-ring is adjacent to chuck in annular.

The seal assembly further includes sealing shroud, and the sealing shroud is that section is in " the cyclic annular revolution of " " shape, the radial direction Sealing "O"-ring is arranged in the inside of sealing shroud and is wrapped by sealing shroud, and the axial seal "O"-ring setting is sealing In set and annular between chuck.

When the utility model is used, circlip selects stainless steel material, inner ring is equipped with a circle latch, and latch is enclosed Annular diameters be less than stainless steel tube to be connected outer diameter.When connecting pipe, latch struts outward, passes through pipeline；It is using In the process, hydraulic pressure has the tendency that making disengagement of pipelines, and the latch of circlip can block pipeline at this time.The utility model, it is easy to operate, It is easy to connect, without being equipped with expensive specific purpose tool and professional operator, connection stainless steel tube can be fast docked, is installed Securely, and there is excellent sealing performance.

The above descriptions are merely preferred embodiments of the present invention, is not to make other forms to the utility model Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent The equivalent embodiment of variation.It is all without departing from the content of the technical scheme of the utility model, according to the technical essence of the utility model pair Any simple modification, equivalent variations and remodeling, still fall within the protection model of technical solutions of the utility model made by above embodiments It encloses.
