Abstract
The utility model provides an anti-disassembly pipe connecting device which comprises a pipe connector, a pipe connecting nut and an elastic washer. The pipe connector comprises a pipe body, an external hexagonal section and an external thread section. A first non-return tooth is arranged on the end face, close to the pipe connector, of the pipe connecting nut. The external hexagonal section comprises a groove and a second non-return tooth, wherein the groove is formed in the end face, close to the pipe connecting nut, of the external hexagonal section, and the second non-return tooth is arranged inside the groove. The pipe body is sleeved with the elastic washer. The elastic washer comprises a base portion and a tilting portion which spirally tilts outwards from the base portion. The base portion is contained inside the groove. The pipe connecting nut and the pipe connector are locked in a rotating mode in the lock-in clock direction. The free end of the base portion is elastically clamped to the second non-return tooth. The free end of the tilting portion is elastically clamped to the first non-return tooth.
