Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in the figure, the automatic finished product device that connects absolutely of rainwater riser for drainage includes

rainwater riser

2, and 2 upper ends of rainwater risers set up roofing rain drop pipe connector 1, the lower extreme sets up building outer wall rain

drop pipe connector

5, and 2 sides of rainwater riser set up breach 8, and 8 departments of breach set up the horizontal drain pipe 6 with 2 normal running fit of rainwater riser, and the terminal surface touches with 2 inner walls of rainwater riser in the horizontal drain pipe 6 and connects airtight cooperation and constitute the drainage channel of L shape.

Furthermore, a left rotating shaft 4 and a right rotating shaft 7 are respectively arranged on two sides of the notch 8, a left rotating shaft hole 9 and a right rotating shaft hole 10 are correspondingly arranged on the pipe wall of the transverse drain pipe 6, and the transverse drain pipe 6 and the rainwater vertical pipe 2 are clamped into the left rotating shaft hole 9 through the left rotating shaft 4 and are clamped into the right rotating shaft hole 10 through the right rotating shaft 7 to be in shaft connection and rotation fit; the transverse drain pipe 6 and the rainwater stand pipe 2 can adopt other rotation matching modes.

Further, the inner end face of the transverse drain pipe 6 is provided with a sealing rubber ring 3, and the transverse drain pipe 6 is tightly attached to the inner wall of the rainwater vertical pipe 2 through the sealing rubber ring 3 and is in contact and close fit with the inner wall, so that the transverse drain pipe 6 is always in a horizontal position when water is not drained and rains for the first time.
