DETAILED DESCRIPTION OF THE INVENTION

[0019] Please refer to FIG. 2, FIG. 3, FIG. 4, the sealing plug A of the present invention includes a cover 3, an installation seat 4 and a floating seat 5, wherein:

[0020] the installation seat 4 is extended from a side of the cover 3, two corresponding arms 41 are set on the installation seat 4, two notches 43 and two guide chutes 44 are respectively set on the corresponding supporting arm 41, the notches 43 are respectively set on the corresponding positioning columns 611 of a flush pipe 61, two guide chutes 44 are connected to a side of the floating seat 5, the floating seat 5 moves along the guide chutes 44 with changes in water level in the toilet tank, the installation seat 4 driven by the buoyancy force on the floating seat 5 generates a leverage moment on a end of the cover 3 to strengthen a pressing force for sealing up the drain opening 621 with the sealing plug A, to thereby improve leak-proof effect.

[0021] The abovementioned cover 3 including a soft plate body 310, the soft plate body 310 is provided to seal up the drain opening 621, two corresponding shaft columns 31 are set on a top side of the cover 3, a through hole 32 set on a front side of the cover 3 is provided to connected to an end of a chain 33.

[0022] The installation seat 4, a hollow section 40 is set in its center, the hollow section is provided for the flush pipe 61 passing through, two shaft holes 42 are respectively set on the front end of the supporting arms 41, the shaft columns 31 are inserted into the corresponding shaft holes 42.

[0023] The floating seat 5, a concave space 53 set inside its seat body 50 is provided to install the floating seat 5 on a peripheral edge of the flush pipe 61, two corresponding stands 51 are set on a side of the floating seat 5, a lug 52 is set on each stand 51, each lug 52 is placed inside each guide chute 44.

[0024] As shown in FIG. 4, in the present invention, by the composition, in sealing state, the floating seat 5 slides upwards to a first end 441 along the guide chutes 44 with changes in water level in the toilet tank due to buoyancy force, the supporting arms 41 are driven, the positioning column 611 is used as a fulcrum, a leverage moment 41 is generated on the end of the cover 3 connected to the supporting arms 41, to strengthen a pressing force for sealing up the drain opening 621 with the sealing plug A, to thereby improve leak-proof effect.

[0025] As shown in FIG. 5 and FIG. 6, when a user flushes a toilet, the chain 33 is pulled upwards and the sealing plug A is lifted up, water inside the toilet tank flows into the overflow pipe 62, and then the sealing plug A lowered and covered on the drain opening 621. The floating seat 5 slides between the second end 442 and the first end 441 of the guide chute 44 with changes in water level in the toilet tank. When the water level in the toilet tank is near full lever, the lug 52 of the floating seat 5 arrives to the first end 441, the supporting arms 41 are driven due to buoyancy force, and a leverage moment is generated to form a pressing force for the sealing plug A. Thus, when water level of the toilet tank is full level, pressing force for sealing up the drain opening 621 with the sealing plug A has fully strengthened (as shown in FIG. 4), to thereby improve leak-proof effect, so the water leakage problem of conventional sealing plugs is solved.
