The invention discloses a liquid-electricity integration quick change joint which comprises a male plug and a female plug, wherein the male plug is composed of a male plug body; a male clamping jaw, a check valve, an electric contact pin and a male fixing part are arranged in the male plug body; the male clamping jaw is fixedly connected with the check valve by the male fixing part after being abutted to the check valve; a sealing ring is arranged at the abutting part of the male clamping jaw and the check valve; the female plug is composed of a female plug body, a check valve, a female fixing part, an electric contact pin seat, a female clamping jaw and a shell; a sealing ring is arranged at the abutting part of the female clamping jaw and the check valve of the female plug; the electric contact pin of the male plug is connected with the electric contact pin seat of the female plug in an inserting manner; the check valve of the male plug is connected with the check valve of the female plug in the inserting manner; and the male plug is fixedly connected with the female plug through a quick fastening device after being connected with the female plug in the inserting manner. According to the liquid-electricity integration quick change joint, with adoption of the technical scheme, a power line, a signal line and a liquid pipeline keep a mutual independent connection manner, normal work of the power line and the signal line cannot be influenced although water in the liquid pipeline leaks, and in addition, the two joints are combined into an integration design and fixed by the quick fastening device, so that the problems of difficulty in disassembling the joints and complex structure with double joints are solved.
