Description

BACKGROUND OF THE INVENTION

a) Field of the Invention

The invention relates to a sealing plug of a toilet tank and, more particularly, to a sealing plug structure for fine-tuning a merged angle automatically, to thereby being covered on the drain opening with different tilt angle.

b) Description of Prior Art

FIG. 1 is a cross-sectional diagram of a conventional toilet tank level structure A, wherein a sealing plug 1 includes a cover 11 and two supporting arms 12, a notch 13 is set on a rear end of the supporting arms 12, the notch 13 is set on a positioning column 211 of a flush pipe 21, the sealing plug 1 is covered on a drain opening 221 of an overflow pipe 22. In is the abovementioned conventional structure, there is a problem in use, it is mainly because that the tilt angle of the drain opening 221 manufactured by different manufacturer may be a little different. The sealing plug 1 is an integrated soft plug body (as shown in FIG. 2). In the early stages of use, the sealing plug 1 could be approximately covered on each type of drain opening 221 with the soft property of its material. But after a period of time, the material of the sealing plug 1 hardens and its original soft elastic property gradually disappears, so that the drain opening 221 cannot be completely covered and water leakage may easily happen. For this reason, consumers are forced to change the sealing plug 1 periodically. Furthermore, consumers usually find water leakage after it happens for a long period of time, so that water rate increases and it also wastes water.

DETAILED DESCRIPTION OF THE INVENTION

Please refer to FIG. 3, FIG. 4 and FIG. 5, the sealing plug 3 of the present invention includes a cover 31 and an installation seat 32, wherein:

the cover 31, two corresponding shaft columns 311 are set on its top;

the installation seat 32, two corresponding supporting arms 320 are set on it, shaft holes 321 are respectively set on a front end of the supporting arms 320, the shaft columns 311 are used to inserted into the shaft holes 321, a notch 324 is set on a rear end of the support arms 320, the notch 324 is used to set on a positioning column 411 of a flush pipe 41;

by the composition, the sealing plug 3 is provided for fine-tuning a merged angle θ automatically, to thereby being covered on the drain opening 421 with different tilt angle.

The abovementioned cover 31 includes a holder 312, a soft plate body 310 and a hemispherical shell 314, the holder 312 is set on the top of the cover 31, a through hole 313 set on a rear end of the holder 312 is provided to connect to an end of a chain 315, the soft plate body 310 fixedly installed between the holder 312 and the hemispherical shell 314 is provided to cover on a drain opening 421 of a toilet tank level structure B, the hemispherical shell 314 is installed on a bottom side of the cover 31.

Please refer to FIG. 5 and FIG. 6, an inner lower slot 322 and an outer upper slot 323 are respectively set on two sides of the front end of each supporting arm 320, the shaft holes 321 are laterally punched through the inner lower slots 322 and the outer upper slots 323, so that the shaft columns 311 may be inserted into the shaft holes 321 and a thicker to clamping and supporting thickness may be provided to prevent it from escaping the shaft holes 321. Also, the merged angle θ for automatically fine tuned between the supporting arms 320 and the cover 31, so that the soft plate body 310 of the cover 31 could be completely covered on the drain opening 421 of the overflow pipe 42.

The supporting arm 320, a clip groove 325 is set on its rear end, the notch 324 is set on a lower side of the clip groove 325 to form two slip side arms 326, 327 for fixedly clipping the positioning column 411 of the flush pipe 41.

By the composition of above structure, when the sealing plug 3 of the present invention is installed to cover on each drain opening 421 manufactured by different manufacturers, even the tilt angle of each drain opening 421 is different, the merged angle θ may be automatically fine tuned between the supporting arms 320 and the cover 31 of the sealing plug 3 of the present invention, so that the soft plate body 310 of the cover 31 could be completely covered on the drain opening 421 of the overflow pipe 42, to thereby extend service life of the sealing plug 3 to prevent water leakage problem, and the disadvantages of the prior art would effectively solved.
