Medical leakage-proof water basin based on water drainage pipe water drainage

The invention belongs to the technical field of water basin leakage prevention and especially relates to a medical leakage-roof water basin based on water drainage pipe water drainage. The medical leakage-proof water basin comprises a water basin body, a plug dish shell, a water accumulation barrel, a first annular sleeve, a plug disk, a threaded barrel, a sealing ring, a second annular sleeve, atrigger block, a pull plate and the like. When the sealing ring has a bad sealing effect, overflowing water can accumulate to a certain degree to press the trigger block downwards, the trigger block which is pressed downwards can pull a fixture block through a pull plate and the steel wire rope to break away from a clamping groove, the plug disk is further broken from the limiting position, a second water drainage hole can be plugged by the plug disk under the reset action of the plug disk spring, finally water in the water basin body cannot be drained out continuously, a user is reminded thatsomething wrong happens u
