Embodiment Construction

[0017] Please refer to FIG. 1. The scaling ring structure of the sinkhole of the present invention includes a base seat 10, a diaphragm 20 and a gum ring 30. Referring to FIGS. 2 to 5, the base seat 10 is a substantially ring-shaped body integrally made of metal or plastic material. The central portion of the base seat 10 is formed with a screen section 11 having multiple perforations 12. The center and other portions of the screen section 11 are respectively formed with holders 13, 14 with a certain size. The upper end of the base seat 1 is formed with a flange 15. The lower end of the base seat 1 is formed with a skirt 16. The skirt 16 is stepped and has a step 161. A lift ring 17 is disposed on the base seat 10 for lifting the sealing ring.

[0018] The diaphragm 20 is substantially a thin disc integrally made of elastic and weatherproof rubber or semisoft plastic material. The diaphragm 20 has chucking bosses 21, 22 respectively corresponding to the holders 13, 14 of the base seat...

Abstract

A sealing ring structure of a sinkhole, which is inlaid in the sinkhole to achieve bugproof and odorproof effects. The sealing ring structure includes a base seat, a diaphragm and a gum ring. The base is a ring body having a screen section formed with multiple perforations. The center and other portions of the screen section are respectively formed with holders. An upper end and a lower end of the base seat are respectively formed with a flange and a stepped skirt. The diaphragm is a gum-made thin disc having chucking bosses inserted in the holders to connect the diaphragm under the base seat with outer circumference of the diaphragm tightly attaching to the stepped skirt of the base seat. The gum ring is fitted around the base seat under the flange thereof. A middle portion of the gum ring is formed with a bight section. When the base seat is placed in the sinkhole, the gum ring is snugly watertight fitted in the sinkhole. The sealing ring can be directly placed in the sinkhole on a stepped shoulder section thereof instead of the conventional petal-type plastic ring to achieve a bugproof and odorproof effect.

Description

BACKGROUND OF THE INVENTION [0001] This application is a Continuation-In-Part of currently pending application U.S. Ser. No. 11 / 130,167, entitled “BUGPROOF AND ODORPROOF SEALING RING STRUCTURE OF A SINKHOLE SCEEN” and filed on May 17, 2005[0002] The present invention is related to an improved sealing ring structure of a sinkhole, and more particularly to a sealing ring structure which is inlaid in a conventional sinkhole to achieve bugproof and odorproof effects. [0003] Taiwanese Patent Publication No. 284567 discloses a petal-type bathroom sinkhole structure. The resilient plastic petal-type plastic ring of the sinkhole structure substantially can achieve a bugproof and odorproof effect. Such sinkhole structure includes a plastic ring with a diameter equal to the diameter of the sinkhole cover. The plastic ring has multiple acute triangular resilient petals radially extending from inner circumference of the plastic ring. The plastic ring is placed on a shoulder section of the sinkh...
