[0020] The adjusting assembly 3 includes a housing 4. On both sides of the housing 4, movable blocks 5 are provided. At the bottom of both movable blocks 5, fixed connection rings 6 are fixedly installed, and the two fixed connection rings 6 are respectively fixedly installed on the outer sides of the two connection flanges 2. Inside the housing 4, a rotating disc 7 is provided. On both sides of the rotating disc 7, first connection shafts 8 are symmetrically and fixedly installed. On the first connection shafts 8, movable connection bars 9 are rotatably installed. At one end of the movable connection bar 9 away from the first connection shaft 8, a second connection shaft 10 is rotatably installed. On the side of the second connection shaft 10 away from the movable connection bar 9, a circular movable plate 11 is fixedly installed. On both sides inside the housing 4, positioning slide rods 18 are symmetrically and fixedly installed, and the two movable rods 12 are respectively located between the two positioning slide rods 18. One end of the positioning slide rod 18 away from the inner wall of the housing 4 movably penetrates through the circular movable plate 11 and extends to the side of the circular movable plate 11 away from the movable rod 12. On the side of the circular movable plate 11 away from the movable rod 12, circular stoppers 19 are symmetrically provided, and one end of the positioning slide rod 18 away from the inner wall of the housing 4 is fixedly connected to the circular stopper 19. In the middle of the side of the circular movable plate 11 away from the second connection shaft 10, a movable rod 12 is fixedly installed, and one end of the movable rod 12 away from the circular movable plate 11 movably penetrates through and extends to the outside of the housing 4 and is fixedly connected to the movable block 5. In the middle of the rotating disc 7, a transmission shaft rod 13 is fixedly and penetratingly installed, and both ends of the transmission shaft rod 13 respectively movably penetrate through and extend to the outside of the housing 4. At one end of the transmission shaft rod 13, an adjusting disc 14 is fixedly installed. On the outer side of the end of the transmission shaft rod 13 away from the adjusting disc 14, locking threads 15 are provided. A locking nut 16 is threadedly installed on the outer side of the locking threads 15, and one side of the locking nut 16 is in contact with the outer side of the housing 4. At the end of the transmission shaft rod 13 away from the adjusting disc 14, a cross-shaped limiting frame 17 is fixedly installed.

[0021] During use, through the interaction of the metal bellows 1, the connection flanges 2 and the adjusting assembly 3, the metal bellows compensator can be quickly adjusted in length during use, improving work efficiency, and thus facilitating better practicality. And through the interaction of the positioning slide rods 18 and the circular stoppers 19, when the circular movable plate 11 moves, better stability can be achieved, thereby ensuring that the adjusting assembly 3 can work stably.

[0022] Working principle: During operation, first hold the adjustment disc 14 stationary to keep the transmission shaft rod 13 stationary. Then loosen the lock nut 16 to release the positioning of the transmission shaft rod 13. Then rotate the adjustment disc 14 to drive the transmission shaft rod 13 to rotate. The transmission shaft rod 13 drives the rotating disc 7 to rotate. The rotating disc 7 drives the first connecting shaft 8 to move. The first connecting shaft 8 drives the movable connecting bar 9 to move. The movable connecting bar 9 pushes the circular movable plate 11 to move through the second connecting shaft 10, so that the circular movable plate 11 slides on the outside of the positioning slide rod 18, which can ensure better stability when the circular movable plate 11 moves. At the same time, the circular movable plate 11 drives the movable rod 12 to move. The movable rod 12 drives the movable block 5 to move. The movable block 5 drives the fixed connecting ring 6 to move. At this time, the two fixed connecting rings 6 move away from each other. The two fixed connecting rings 6 respectively drive the connecting flanges 2 connected to them to move. The two connecting flanges 2 move away from each other to stretch and adjust the length of the metal bellows 1. After reaching the required length, stop rotating the adjustment disc 14. Then hold the adjustment disc 14 stationary to keep the transmission shaft rod 13 stationary. Then tighten the lock nut 16 to reposition the transmission shaft rod 13. Then release the adjustment disc 14 to complete the length adjustment operation of the metal bellows compensator. Through the above operations, it is possible to avoid the situation of rotating multiple nuts and screws outside the metal bellows compensator when adjusting its length. In this way, during the use of the metal bellows compensator, it is convenient to quickly perform the length adjustment operation, improving work efficiency and thus facilitating better practicality.
