Rotary pipeline connecting system

Abstract

The invention discloses a rotary pipeline connecting system. The rotary pipeline connecting system comprises rotary connector assemblies. Each rotary connector assembly comprises a water storage elbow and a straight connecting pipe which is arranged in the water storage elbow in a sleeved mode and can rotate. Every two adjacent rotary connector assemblies are connected through the elbows. Each water storage elbow comprises a vertical pipe, a side pipe, a casing pipe and a water storage elbow end enclosure, wherein the casing pipe is arranged in the vertical pipe, and a U-shaped gap is formed between the corresponding bottoms and side walls of the casing pipe and the vertical pipe and communicated with the side pipe. Inverted-cone-shaped rotary bosses used for being inserted into the casing pipes are arranged at the lower ends of the straight connecting pipes, necks are arranged at the bottom ends of the rotary bosses, the necks extend upwards to form neck grooves, and the rotary bosses abut against the inner walls of the casing pipes. The straight connecting pipes and the water storage elbows can be rotationally connected; besides, the U-shaped gaps formed by the vertical pipes and the casing pipes can effectively prevent peculiar smells from rising, and the deodorant function is achieved.

Description

technical field [0001] The invention relates to a water supply and drainage system, in particular to a rotatable pipeline connection system. Background technique [0002] For fixed sewer devices (for example: sinks, bathroom basins), sewer pipes generally use fixed drainage pipes, but now many sewer devices are movable. For such movable sewer devices, drainage pipes generally use plastic bellows or Plug-in telescopic tube; the inner wall of the plastic bellows is corrugated. After a long time, the inner wall is prone to fouling and emits odors, and because it is an active sewer device, the bellows will also move with the sewer device. The outer wall of the bellows Rubbing back and forth with the ground, the corrugated tube is easy to wear and tear; the expansion distance of the plug-in telescopic tube is large and it is easy to be damaged. At the same time, in order to ensure flexible expansion and contraction, the seal should not be too tight. It is too laborious to tighte...

[0002] For fixed sewer devices (for example: sinks, bathroom basins), sewer pipes generally use fixed drainage pipes, but now many sewer devices are movable. For such movable sewer devices, drainage pipes generally use plastic bellows or Plug-in telescopic tube; the inner wall of the plastic bellows is corrugated. After a long time, the inner wall is prone to fouling and emits odors, and because it is an active sewer device, the bellows will also move with the sewer device. The outer wall of the bellows Rubbing back and forth with the ground, the corrugated tube is easy to wear and tear; the expansion distance of the plug-in telescopic tube is large and it is easy to be damaged. At the same time, in order to ensure flexible expansion and contraction, the seal should not be too tight. Tightening and stretching is too laborious, and the axial friction between the inner wall of the pipe and the seal is likely to cause the seal to be cut or severely worn, and water will also leak
