Stainless steel pipe fitting connecting structure

The invention relates to the related technical field of stainless steel pipe fittings, and discloses a stainless steel pipe fitting connecting structure which comprises a first connector and a second connector, the first connector and the second connector are connected through a thread structure, three annular semicircular rings are arranged on the matched connecting end face of the first connector, and an annular adjusting pad is arranged at the matched inner end of the second connector. An annular semicircular groove matched with the annular semicircular ring is formed in the end face, close to the first connector, of the annular adjusting pad, and a rotary connector is installed on the other end face of the annular adjusting pad. According to the stainless steel pipe fitting connecting structure, the sealing gaskets are pressed to achieve the sealing effect, the three sealing gaskets are in three-layer sealing from inside to outside, and the sealing rings are different from traditional planar sealing rings
