[0027] A type of pipe elbow, such as Figures 1 to 5 As shown, the device includes an elbow body 1, with a set of connectors 2 connected to both ends of the elbow body 1. Each connector 2 includes a connecting pipe 201 connected to the end of the connector 2. A threaded sleeve 202 is threadedly connected to the end of the connecting pipe 201. A pressure ring 203 is slidably connected to the inner wall of the connecting pipe 201. The top end of the pressure ring 203 is fitted against the outer wall of the threaded sleeve 202. An inner rubber sleeve 204 is fixedly fitted onto the inner wall of the connecting pipe 201. An outer rubber sleeve 205 is fixedly fitted onto the inner wall of the connecting pipe 201, located next to the inner rubber sleeve 204. The outer rubber sleeve 205 is fitted over the inner rubber sleeve 204. The bottom end of the pressure ring 203 abuts against the inner rubber sleeve 202.

The elbow body 1 is rotatably connected to a set of fixing components 3 at the connection points with the two sets of connecting pipes 201. The fixing components 3 include a rotating ring 301, which is rotatably connected to the connection point between the elbow body 1 and the connecting pipe 201. A rotating plate 302 is rotatably connected to the side wall of the rotating ring 301. A set of fixing plates 303 are rotatably connected to both ends of the rotating plate 302. Each set of fixing plates 303 has an opening through the fixing plate 303 on its side wall.

[0028] By inserting the pipe between the inner rubber sleeve 204 and the outer rubber sleeve 205 and then rotating the threaded sleeve 202, the threaded sleeve 202 moves on the outer wall of the connecting pipe 201 through the thread, and the threaded sleeve 202 pushes the pressing block during the movement, so that the pressing ring 203 pushes the outer rubber sleeve 205, so that the pressing ring 203 tightly presses the outer rubber sleeve 205 on the outer wall of the pipe, so that the bend body 1 and the pipe can be sealed, and the inner rubber sleeve 204 is further improved in sealing by being tightly fitted on the inner wall of the pipe through its own elasticity, thereby completing the connection of the bend body 1 and the pipe. When disassembling, only need to rotate the threaded sleeve 202 in the opposite direction, so that the pressing block no longer pushes the outer rubber sleeve 205, and the pipe can be separated from the connector 2 by pulling. By pushing the rotating plate 302 to rotate and the fixing piece 303 to flip, so that the openings with bolt holes on the fixing piece 303 are aligned, so that it is more convenient to further fix the bend body 1 by bolts.

[0029] Please refer to Figure 3 , the bend body 1 is communicated with the compression-resistant assembly 4, the compression-resistant assembly 4 includes a sleeve 401, the inner wall of the sleeve 401 is slidably sleeved with a piston 402, the sleeve 401 and the piston 402 are fixedly connected with a rubber capsule 403, the inner wall of the rubber capsule 403 is filled with compressed air, the inner wall of the rubber capsule 403 is sleeved with a buffer spring 404, one end of the buffer spring 404 is fixedly connected to the side wall of the piston 402, and the other end of the buffer spring 404 is fixedly connected to the inner wall of the sleeve 401.

[0030] When the water flow impacts the bend of the bend body 1, the impact force pushes the piston 402 to slide on the inner wall of the sleeve 401, so that the piston 402 compresses the buffer spring 404 and the rubber capsule 403, and the impact of the water flow is buffered through the deformation of the buffer spring 404 and the rubber capsule 403, thereby avoiding that the impact force on the bend of the bend body 1 is too large when the water flow is large, and reducing the damage caused by water hammer effect to the bend body 1.
