[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0020] The present utility model provides a technical solution: As Figures 1 to 4 shown, in this embodiment, an adjustable pipe assembly connector includes a semi-circular pipe 1. There are four semi-circular pipes 1, and two semi-circular pipes 1 form a group. Ear plates 2 are symmetrically and fixedly installed on both sides of the semi-circular pipe 1. A fixing bolt 3 is installed between the two ear plates 2 on the same side. A metal bellows 4 is installed between the two groups of semi-circular pipes 1. A fixing ring 5 is fixedly installed at the end of the metal bellows 4. A positioning semi-circular ring 6 is fixedly installed on the inner wall of the semi-circular pipe 1. An elastic sealing ring 7 is installed on one side of the two positioning semi-circular rings 6. The fixing ring 5 is in pressing contact with one side of the elastic sealing ring 7. Move the circular pipe formed by the two groups of semi-circular pipes 1 towards each other, which will squeeze the metal bellows 4 and drive the metal bellows 4 to compress. Place the circular pipe formed by the two groups of semi-circular pipes 1 between two pipes, and then pull the circular pipe formed by the two groups of semi-circular pipes 1 to sleeved the circular pipe outside the two pipes to be installed. At this time, the fixing ring 5 at the end of the metal bellows 4 will squeeze one side of the elastic sealing ring 7 to ensure the seal between the fixing ring 5 and the elastic sealing ring 7. Then pull the circular pipe formed by the two groups of semi-circular pipes 1 to make the fixing ring 5 close to the elastic sealing ring 7, and then install and fix the two groups of semi-circular pipes 1 through the fixing bolt 3 to facilitate the assembly between the two pipes.

[0021] As Figures 1 to 4 shown, a limiting hole 8 is annularly and arrayedly opened in the middle of the fixing ring 5 with the central axis of the fixing ring 5 as the axis. A limiting rod 9 is slidably installed inside the limiting hole 8. A positioning spring 10 is sleeved outside the end of the limiting rod 9. One end of the positioning spring 10 is fixedly connected to the end of the limiting rod 9, and the other end of the positioning spring 10 is fixedly connected to the inner wall of the fixing ring 5. A first through hole 11 is opened on the semi-circular pipe 1 corresponding to the position of the limiting rod 9, and the first through hole 11 is slidably connected to the limiting rod 9.

[0022] When installing the metal bellows 4, the limiting rod 9 is completely received inside the limiting hole 8 of the fixing ring 5 and inside the metal bellows 4. At this time, the positioning spring 10 is in a stretched state. Then slide the fixing ring 5 at the end of the metal bellows 4 to one side of the positioning semi-circular ring 6, and then under the pulling of the positioning spring 10 on the limiting rod 9, slide the limiting rod 9 into the first through hole 11 for installing the metal bellows 4 to ensure the effective pressing seal between the fixing ring 5 and the elastic sealing ring 7.

[0023] As Figures 1 to 4 shown, a fastening bolt 12 is threadedly connected to the end of the limiting rod 9 away from the positioning spring 10.

[0024] For stably fixing between the fixed ring 5 and the positioning semi-circular ring 6.

[0025] As Figures 1 to 4 shown, a rubber sealing ring 13 is installed on the outer ring of the fixed ring 5, and a second through hole 14 is opened at the position of the rubber sealing ring 13 corresponding to the limiting rod 9, and the limiting rod 9 is arranged through the second through hole 14.

[0026] For sealing between the outer ring of the fixed ring 5 and the semi-circular pipe 1.

[0027] As Figures 1 to 4 shown, one end of one of the semi-circular pipes 1 is fixedly installed with an arc-shaped plate 15, and the end of the arc-shaped plate 15 is fixedly installed with an arc-shaped slider 16. An arc-shaped sliding groove 17 is opened at the end of the other semi-circular pipe 1 opposite to and relative to the semi-circular pipe 1 installed with the arc-shaped plate 15, and the arc-shaped sliding groove 17 is slidably connected with the arc-shaped slider 16.

[0028] When relatively moving the two groups of semi-circular pipes 1, the two groups of semi-circular pipes 1 can be limited in relative movement first.

[0029] As Figures 1 to 4 shown, the metal bellows 4 can only be compressed and will not be distorted.

[0030] For preventing the state of internal distortion of the metal bellows 4 when the metal bellows 4 is compressed, and preventing the excessive impact of water on the inner wall of the compressed metal bellows 4.

[0031] The present utility model provides an adjustable pipe assembly connecting piece, and the specific working principle is as follows:

[0032] When the device is in use, move the circular pipe formed by the two groups of semi-circular pipes 1 towards each other, which will squeeze the metal bellows 4 and drive the metal bellows 4 to be compressed. Place the circular pipe formed by the two groups of semi-circular pipes 1 between two pipes, and then pull the circular pipe formed by the two groups of semi-circular pipes 1 to sleeved on the outer sides of the two pipes to be installed. At this time, the fixed ring 5 at the end of the metal bellows 4 will squeeze one side of the elastic sealing ring 7 to ensure the seal between the fixed ring 5 and the elastic sealing ring 7. Then pull the circular pipe formed by the two groups of semi-circular pipes 1 to make the fixed ring 5 close to the elastic sealing ring 7, and then install and fix the two groups of semi-circular pipes 1 through the fixing bolts 3 to facilitate the assembly between the two pipes.
