Sealing ring structure of a sinkhole

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...

AI Technical Summary

Benefits of technology

[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.

[0004] It is therefore a primary object of the present invention to provide a sealing ring structure of a sinkhole. The sealing ring structure is directly inlaid in the sinkhole on a stepped shoulder section thereof instead of the conventional petal-type plastic ring. The sealing ring structure has a disc-shaped diaphragm which is able to truly achieve a bugproof and odorproof effect.

[0008] a gum ring fitted around the base seat, a middle portion of the gum ring being 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. Therefore, the stink and insects are prevented from entering the kitchen or the room.

Problems solved by technology

Therefore, after a period of use, the resilient plastic petals of the plastic ring tend to elastically fail and deform and become suspend from the inner circumference of the plastic ring.

Under such circumstance, the petals can no more shade the sinkhole and the plastic ring will lose its bugproof and odorproof function.
