Traditional fixed-angle elbows are typically made by integral casting or welding. However, they also present the following problems in use:

[0003] The current grooved elbow assembly is difficult to adjust in terms of orientation after installation and fixing. Even if it is adjusted, it is limited by the position of the connecting flange hole, and can only adjust the angle corresponding to the hole position. If the pipeline needs to be modified, and the orientation of the pipeline is adjusted later, the original elbow cannot be adapted, and the entire elbow needs to be removed, resulting in poor practicality.

An adjusting screw is also rotatably connected to the edge of one side of the connecting ring seat. The adjusting screw passes through the annular disc and is threadedly connected to the annular disc. A first rotating head is fixedly connected to the top of the adjusting screw.

[0007] The technical effect achieved by the above solution is that by rotating the adjusting screw, the annular disc can be driven to slide along several guide rods, and then the annular disc can drive the corrugated telescopic tube to stretch or retract, thereby achieving length adjustment.

[0008] Preferably, in any of the above embodiments, the lengths of the guide rods are adapted to the lengths of the adjusting screws, the lengths of the guide rods and the adjusting screws are adapted to the lengths of the fully extended corrugated telescopic tube, and the guide rods and the adjusting screws are distributed in a circular array around the center of the connecting ring seat.

[0009] The technical effect achieved by adopting the above solution is to improve the uniformity of force distribution and to make the adjustment length match the expandable length of the corrugated expansion tube.

[0010] Preferably, in any of the above embodiments, the diameter of the connecting flange is larger than the diameter of the connecting ring seat, and a sealing gasket is fixedly connected to the surface of the connecting flange.

[0015] 1. This multi-angle adjustable groove elbow assembly can rotate the driven worm gear by rotating the drive worm, which in turn can rotate the corrugated expansion pipe and the elbow, thereby changing the orientation of the other end. This allows the orientation to be adjusted according to the subsequent pipeline layout direction after pipeline modification. Moreover, after adjustment, the driven worm gear can automatically fix the driven worm gear through locking, achieving the purpose of easy adjustment.

[0016] 2. This multi-angle adjustable groove elbow assembly can drive the annular disc to slide along several guide rods by rotating the adjusting screw.
