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.

1 . A sealing ring structure of a sinkhole, comprising: 
 a base seat which is a substantially ring-shaped body having a screen section, the screen section being formed with multiple perforations, a central portion and a circumferential portion of the screen section being respectively formed with holders, an upper end of the base seat being formed with a flange, a lower end of the base seat being formed with a skirt;    a diaphragm which is substantially a gum-made thin disc, the diaphragm having chucking bosses respectively corresponding to the holders of the base seat, the chucking bosses being inserted in the holders to connect the diaphragm with the base seat with outer circumference of the diaphragm tightly attaching to the skirt of the base seat; and    a gum ring fitted around the base seat, when base seat is placed in the sinkhole, the gum ring being snugly watertight fitted in the sinkhole, whereby the sealing ring can be directly placed in the sinkhole on a shoulder section thereof to achieve a bugproof and odorproof effect.

       5 . The sealing ring structure of the sinkhole as claimed in  claim 1 , wherein a lift ring is disposed on inner circumference of the base seat.  
   
   
       6 . The sealing ring structure of the sinkhole as claimed in  claim 2 , wherein a lift ring is disposed on inner circumference of the base seat.  
   
   
       7 . The sealing ring structure of the sinkhole as claimed in  claim 3 , wherein a lift ring is disposed on inner circumference of the base seat.  
   
   
       8 . The sealing ring structure of the sinkhole as claimed in  claim 1 , wherein the skirt of the base seat is stepped and has a step section, whereby the outer circumference of the diaphragm can snugly attach to the step section of the skirt.  
   
   
       9 . The sealing ring structure of the sinkhole as claimed in  claim 2 , wherein the skirt of the base seat is stepped and has a step section, whereby the outer circumference of the diaphragm can snugly attach to the step section of the skirt.  
   
   
       10 . The sealing ring structure of the sinkhole as claimed in  claim 3 , wherein the skirt of the base seat is stepped and has a step section, whereby the outer circumference of the diaphragm can snugly attach to the step section of the skirt.  
   
   
       11 . The sealing ring structure of the sinkhole as claimed in  claim 4 , wherein the skirt of the base seat is stepped and has a step section, whereby the outer circumference of the diaphragm can snugly attach to the step section of the skirt.  
   
   
       12 . The sealing ring structure of the sinkhole as claimed in  claim 1 , wherein a pinch button formed with slipproof stripes is disposed on upper end of the central chucking boss of the diaphragm.  
   
   
       13 . The sealing ring structure of the sinkhole as claimed in  claim 2 , wherein a pinch button formed with slipproof stripes is disposed on upper end of the central chucking boss of the diaphragm.  
   
   
       14 . The sealing ring structure of the sinkhole as claimed in  claim 1 , wherein the gum ring is fitted around the base seat under the flange thereof.  
   
   
       15 . The sealing ring structure of the sinkhole as claimed in  claim 8 , wherein the gum ring is fitted around the base seat under the flange thereof.  
   
   
       16 . The sealing ring structure of the sinkhole as claimed in  claim 1 , wherein a middle portion of the gum ring is formed with a bight section.  
   
   
       17 . The sealing ring structure of the sinkhole as claimed in  claim 8 , wherein a middle portion of the gum ring is formed with a bight section.  
   
   
       18 . The sealing ring structure of the sinkhole as claimed in  claim 11 , wherein a middle portion of the gum ring is formed with a bight section.  
   
   
       19 . The sealing ring structure of the sinkhole as claimed in  claim 12 , wherein a middle portion of the gum ring is formed with a bight section.  
   
   
       20 . The sealing ring structure of the sinkhole as claimed in  claim 14 , wherein a middle portion of the gum ring is formed with a bight section.
