Detailed Description

The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The basic principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents and other technical solutions without departing from the spirit and scope of the invention.

It will be understood by those skilled in the art that in the present disclosure, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in a generic and descriptive sense only and not for purposes of limitation, as the terms are used in the description to indicate that the referenced device or element must have the specified orientation, be constructed and operated in the specified orientation, and not for the purposes of limitation.

A stainless steel pipe fitting joint according to a preferred embodiment of the present invention is described in detail below with reference to fig. 1 and 2, wherein the stainless steel pipe fitting joint includes a first joint end portion 10, a second joint end portion 20, and a bent pipe portion 30. One end of the bent pipe portion 30 extends integrally from the first joint end portion 10 in the same plane direction as the first joint end portion 10. The other end of the bent pipe portion 30 integrally extends to form a second joint end portion 20. The first joint end 10 and the second joint end 20 are respectively provided at positions that are not collinear at both ends of the elbow 30. With this arrangement, when the first joint end 10 or the second joint end 20 is connected to a pipe body, the second joint end 20 or the first joint end 10 can be held at a position that is not collinear with the first joint end 10 or the second joint end 20.

With such a design, when the stainless pipe joint is mounted to a gas range, a hose for butting against the stainless pipe joint can be further away from the gas range, thereby preventing the hose from being softened by overheating.

Specifically, the first joint end 10 and the second joint end 20 of the stainless pipe joint are respectively implemented as a through pipe. The first joint end 10 is provided with a coupling nut 40. The coupling nut 40 is defined at the first joint end 10 for sealingly threaded connection to a threaded metal pipe.

The first joint end 10 has a butt end 11, wherein after the connection nut 40 is sleeved on the first joint end 10, the end of the butt end 11 forms an annular convex hull 102 on the butt end 11 through a rotary hull device. By means of the annular convex hull 102, the coupling nut 40 will be restrained at the first joint end 10 and the coupling nut 40 can slide along the first joint end 10. The coupling nut 40 has a bottom wall 41, wherein the bottom wall 41 forms a sleeve bore 4101. The peripheral edge of the bottom wall 41 integrally extends to form a peripheral side wall 42, wherein the cross-sectional shape of the peripheral side wall 42 is implemented as a regular polygon, so that the coupling nut forms a polygonal nut. The inner wall of the peripheral side wall 42 is formed with a screw thread. The peripheral sidewall 42 further defines a nut port 4201. Preferably, the polygonal nut is implemented as a hexagonal nut.

The mating end 11 of the first joint end 10 is insertable through the sleeve hole 4101 of the bottom wall 41 and protrudes from the nut port 4201 such that the coupling nut 40 is sleeved on the first joint end 10. After the coupling nut 40 is sleeved on the first joint end 10, the annular convex hull 102 can be formed on the butt end 11 of the first joint end 10 by a rotating equipment. The cross-sectional diameter of the annular convex hull 102 is greater than the cross-sectional diameter of the first joint end 10 and less than the cross-sectional dimension of the nut port 4201 formed in the peripheral sidewall 42. Subsequently, the bottom wall 41 of the coupling nut 40 is blocked by the annular convex hull 102 and is thus confined to the first joint end 10. At the same time, the coupling nut 40 can slide along the first joint end 10.

It is worth mentioning that the first joint end 10 is sleeved with at least one sealing ring 50, wherein the sealing ring 50 is arranged between the annular convex hull 102 and the bottom wall 41 of the coupling nut 40 after the annular convex hull 102 is formed, so that when the coupling nut 40 is butted against another metal pipe, the sealing ring 50 is compressed between the annular convex hull 102 and the bottom wall 41 of the coupling nut 40, thereby providing a good sealing performance between the first joint end 10 and the other metal pipe.

More preferably, in another embodiment of the present invention, the butt end 11 of the first joint end 10 is provided with a thread, wherein a part of the thread of the inner wall of the peripheral side wall 42 of the coupling nut 40 can be screwed at the thread of the first joint end 10. And another part of the threads of the inner wall of the peripheral side wall 42 of the coupling nut 40 can be screwed to the metal pipe.

In this embodiment, the coupling nut 40 can be disengaged from the threads of the mating end 11 after the coupling nut 40 continues to rotate. Further, the stainless steel pipe fitting joint further includes a stretchable pipe 60 and a fixing nut 70. The stretchable tube 60 has a first threaded rigid portion 61, a second threaded rigid portion 62 and a stretchable portion 63. The first hard threaded portion 61 is screwed to the coupling nut 40, and the second hard threaded portion 62 is screwed to the fixing nut 70. The telescopic part 53 is sleeved on the first joint end 10. The fixing nut 70 is screwed to the stainless steel pipe fitting joint.

In the present embodiment, the coupling nut 40 has a first nut portion 401 and a second nut portion 402. The first nut portion 401 has a cross-sectional diameter smaller than that of the second nut portion 402. The stretchable tube 60 has a larger cross-sectional diameter than the first joint end 10. The first nut portion 401 is threadably connected to the mating end 11 threaded portion. The second nut portion 402 is threadably fixed to the second threaded hard portion 62.

When the first joint end 10 is extended in a direction conforming to the orientation of the desired joint, it is possible to directly connect the metal pipe to the coupling nut 40 by screwing. When the extending direction of the first coupling end portion 10 does not conform to the orientation of the coupling required, the coupling nut 40 may be directly rotated away from the coupling end 11, and then the direction of the coupling nut 40 may be adjusted by pulling the stretchable tube 60.

In this way, the stainless steel pipe fitting joint can be screwed with the metal pipe in different directions.

As can be appreciated by a person skilled in the art, the telescopic part 53 is embodied as a stretchable corrugated hose. The first thread hard portion 61 and the second thread hard portion 62 are implemented to be made of a plastic material.

It is also worth mentioning that the first and second

fitting end portions

10, 20 and the elbow portion 30 of the stainless steel pipe fitting are all embodied as being made of a stainless steel material.

It will be understood by those skilled in the art that the embodiments of the present invention as described above and shown in the drawings are given by way of example only and are not limiting of the present invention. The objects of the present invention have been fully and effectively accomplished. The functional and structural principles of the present invention have been shown and described in the embodiments without departing from the principles, embodiments of the present invention may have any deformation or modification.
