A connecting device for reducing noise in a drain pipe is provided to decrease noise between floors in draining water by reducing the flow rate of water and guiding water along the inner wall of the drain pipe. A connecting device includes an upper housing(10), a lower housing(20), an SGT(sponge gourd tissue) filter(40), and a flow guide distribution plate(50). The lower part of a drain pipe is inserted to the upper housing, and a radial support unit(12), plural assembling holes(13) and a skirt part(14) are formed in the upper housing. Assembling projections(25) are bent outward and combined with a three-way assembling unit(30) formed in the skirt part. Clips(26) are formed symmetrically in the inner periphery of the lower housing, and a radial support unit(22) is formed in the lower part of the lower housing. A groove(41) is formed in the outer periphery of the SGT filter. The flow guide distribution plate has a support bar(52) inserted to a support hole of the clip, a guide pipe(51), guide projections(54) arranged radially to guide water from the SGT filter to an inner wall of a drain pipe, and an expanded guide unit(53). The assembling projections are inserted to opening grooves(31) in the three-way assembling unit, and plural fitting grooves(32) are connected to the opening groove to turn horizontally and fix the assembling projection. |
