Overflow pipe assembly

Abstract

An overflow pipe assembly includes an overflow pipe having an end portion. An adaptor is connected to the end portion of the overflow pipe and includes a first connection portion formed to the center thereof. A second connection portion which is a slot, and a third connection portion which is a bore, are respectively formed to two ends of the adaptor. A cover includes multiple protrusions which are engaged with the engaging portions of the adaptor to connect the cover to the adaptor. When installing the adaptor to an overflow pipe with two tubular parts, the adaptor does not shift by extending bolts through the second and third connection portions and connected to the two tubular parts. When installing the adaptor to an overflow pipe with a single tube, a bolt extends through the first connection portion and is connected to the tube.

What is claimed is: 
     
         1 . An overflow pipe assembly, comprising:
 an overflow pipe having an end portion;   an adaptor being an elongate plate, a length of the elongate body being not longer than a diameter of the end portion of the overflow pipe, the adaptor connected to the end portion of the overflow pipe and including a first connection portion formed to a center thereof, the first connection portion being a hole, a second connection portion and a third connection portion respectively formed to two ends of the adaptor, the second connection portion being a slot, the third connection portion being a bore, two engaging portions respectively formed to two sides of the adaptor, and   a cover having at least one drainage formed to a periphery thereof, the at least one drainage communicating with the end portion of the overflow pipe, multiple protrusions extending from an inner bottom of the cover, the protrusions engaged with the engaging portions of the adaptor so as to connect the cover to the adaptor.   
     
     
         2 . The overflow pipe assembly claimed in  claim 1 , wherein the engaging portions are two straight sides, each of the protrusions of the cover includes a root extending from the inner bottom of the cover, a hook is formed to a distal end of the root, the protrusions are located corresponding to the two engaging portions and arranged in two rows, the hooks of two rows of the protrusions face each other. 
     
     
         3 . The overflow pipe assembly as claimed in  claim 1 , wherein a tube is located along an axis of the end portion of the overflow pipe, a first threaded hole is formed in a distal end of the tube and located corresponding to the first connection portion of the adaptor, a bolt extends through the first connection portion of the adaptor and is connected to the first threaded hole of the tube, multiple ribs protrude from a periphery of the first connection portion to increase an axial height of the first connection portion. 
     
     
         4 . The overflow pipe assembly as claimed in  claim 1 , wherein two tubular parts are respectively formed to an inner periphery of the end portion of the overflow pipe, the two tubular parts respectively includes a second threaded hole and a third threaded hole formed to a distal end thereof, the second and third threaded holes are located corresponding to the third connection portion and the second connection portion of the adaptor, two bolts extend through the second connection portion and the third connection portion of the adaptor, and are connected to the second and third threaded holes.
