Hanging formwork structure of sunken toilet

The utility model discloses a hanging formwork structure of a sunken toilet, which comprises an outer layer formwork and an inner layer formwork, a water stop bolt is fixedly connected between the outer layer formwork and the inner layer formwork, and two ends of the water stop bolt respectively penetrate through the outer layer formwork and the inner layer formwork. And a first water stop nut anda second water stop nut which are in threaded fit with the outer-layer template and the inner-layer template are arranged on the water stop bolt between the outer-layer template and the inner-layer template, so that a pouring mold cavity is formed between the outer-layer template and the inner-layer template. The formwork is novel in structure, the inner-layer formwork is fixed through the waterstop bolts, the outer-layer formwork and the inner-layer formwork are evenly stressed and not prone to deformation, the phenomena of asymmetry in shape, deflection angles, formwork expansion and slagfalling of the edge of a su
