The thread insert 3 is hermetically connected with the external pipe fitting 2, and the external connection mode of the thread insert 3 can be determined according to the requirement.
The external interface of the external pipe fitting 2 or the threaded sleeve 3 in the technical scheme can be a straight pipe or an elbow pipe. An angle valve can be additionally connected to be used as a unit component.
The utility model relates to an outer coupling assembling of nonrust steel pipe mainly is applied to among the water and other fluidic conveying pipeline. Because the utility model discloses simple structure, dependable performance intensity is high, and the installation is swift convenient, and the cost is on the low side, more is fit for general water supply engineering demand.

Detailed Description
The embodiment of the utility model provides a
Fig. 1 is a plan sectional view of the present embodiment, showing the structure of the present embodiment. Fig. 2 is an enlarged view of the portion B of fig. 1, showing a sectional view of the snap ring groove 22 of the inner cavity of the outer joint member 2, the annular groove 11 of the outer circumference of the stainless steel pipe 1, and the snap ring 4 inserted therein.
An external connection component of a stainless steel pipe comprises a stainless steel pipe 1 and an external connection component sleeved on the end of the stainless steel pipe 1, wherein the external connection component comprises an external pipe fitting 2, a screw sleeve 3 which can be fixedly connected with the external pipe fitting through threads, an elastic split snap ring 4 and an O-shaped ring 5, at least one annular O-shaped ring groove 21 is arranged along the circumference of the inner wall of an inner cavity of the external pipe fitting 2 which is slidably sleeved with the stainless steel pipe 1, the O-shaped ring 5 is embedded in the O-shaped ring groove 21 and is tightly connected with the outer circumferential surface of the inserted and slidably matched stainless steel pipe to play an axial seal, an annular snap ring groove 22 and a split snap ring 4 are further arranged at the axial position of the inner cavity of the external pipe fitting 2 and at the inner side or the outer side of the O-shaped ring groove 21, the maximum diameter of the snap ring groove 22 is larger than the outer diameter of the, The axial position corresponding to the snap ring groove 22 that sets up with the outer pipe fitting 2 inner chamber sets up an annular groove 11, the maximum diameter of the snap ring groove 22 of outer pipe fitting 2 will be greater than the certain yardstick of the opening snap ring 4 external diameter to make the end of stainless steel pipe 1 when inserting the inner chamber of outer pipe fitting 2, and until inserting opening snap ring 4, opening snap ring 4 can elastic expand and expand, make it insert smoothly, and hold tightly in the annular groove 11 of stainless steel pipe 1 afterwards, the position of outer pipe fitting 2 on stainless steel pipe 1 is pinned to the axial.
The thread insert 3 is connected with the external pipe fitting 2 in a sealing mode, and then is connected with the outside through the thread insert 3, and the external connection mode can be determined according to actual needs. Of course, in order to facilitate the insertion of the stainless steel pipe 1 into the external pipe fitting 2, the end of the stainless steel pipe 1 needs to be slightly rounded, and the processing of the annular groove on the outer circumference of the stainless steel pipe has a special tool, so that the processing of the thread on the stainless steel pipe is far from simple.
The external interface of the external pipe fitting 2 or the threaded sleeve 3 in the technical scheme can be a straight pipe or an elbow pipe. An angle valve can be additionally connected to be used as a unit component.
