Description

Technical Field

[0001] The utility model relates to the technical field of pipe fitting connection, and more specifically to a pipe fitting assembly with adjustable rotation angle. Background Art

[0002] Drainage fittings are extremely important components in the drainage network. They have a variety of auxiliary drainage functions and are an indispensable part of the network. Pipe connection, as the most basic and important function of pipe fittings, plays the role of connecting two pipes. In actual application, it is often limited by factors such as the terrain of the construction site. When laying out the pipeline, it is often necessary to make multiple detours. Therefore, it is necessary to use pipe fittings with various bending angles to achieve the connection between the pipelines. At present, most elbow fittings are standard parts with fixed connection angles, which cannot meet the use requirements of multi-angle connection. In some cases, multiple elbow fittings can be used to connect the splicing angles in sequence, but the connectable angles are also relatively small, and the operation is also quite troublesome.

[0003] In the prior art, a rotating pipe fitting joint is disclosed. The rotating pipe fitting joint is composed of two parts. The two parts are curved, straight, or curved straight. The two parts of the pipe fitting joint are assembled separately and staggered. There is an intersection circular surface at the connection point. The intersection circular surface has convex and concave positioning steps. The two convex and concave intersection circular surfaces overlap. The tops of the two connecting structures are respectively provided with perforations. Bolts are inserted through the perforations to connect the two parts of the pipe fitting body together. The two parts of the pipe fitting body are positioned with the convex and concave steps with the bolts as the axis. They are on the same plane and can be staggered and rotated and can be positioned. The tops of the two pipe fitting bodies are in an arc shape or a trapezoidal shape. There are positioning pins and sealing gaskets at the overlap of the two intersection circular surfaces. The convex and concave step positioning refers to the rotation plane positioning, and the pin positioning refers to the rotation angle positioning. This type of rotating pipe joint can achieve connection at many angles, but the turning part of this type of rotating pipe joint is cylindrical, and the transition with the water flow channels on both sides is not smooth. Impurities are easily accumulated at the turning part, which is easy to block the channel. Bolts are used to fix the turning part, which is also easy to block impurities and rust, and the connection sealing is not good. At the same time, the existing rotating pipe joints cannot accurately determine the rotation angle when connecting, and can only be connected at an approximate angle. The connection accuracy is insufficient, which may lead to poor connection sealing and easy water seepage and leakage. Utility Model Content
