The utility model provides a non-metal expansion joint capable of avoiding liquid leakage caused by pipeline expansion, which comprises a left connecting flange, and a telescopic elastic pipe is fixedly connected in the left connecting flange. According to the non-metal expansion joint capable of avoiding liquid leakage caused by pipeline expansion, a buckling block is rotated, so that the buckling block is clamped to the outer walls of the right connecting flange and the connecting pipe, a fixing rod is pressed, so that a clamping head is clamped into a fixing groove, and therefore the effects that the non-metal expansion joint and the connecting pipe are conveniently and rapidly fixed, and the working efficiency is improved are achieved. Under the impact of pressure, the telescopic elastic pipe can be pressed to expand, deform and deviate, the ball can rotate in the connecting block, the left connecting flange and the right connecting flange have high rotation performance, and the telescopic elastic pipe is
