A metal bellows 2 is fixedly installed between the two flanges 1. An anti-impact component 3 is arranged on the outer side of the metal bellows 2, and both ends of the anti-impact component 3 are respectively connected to the outer sides of the two flanges 1;

[0021] The impact-resistant component 3 includes connection frames 4 symmetrically arranged, and the two connection frames 4 are respectively fixedly installed on the outer sides of the two flanges 1. Four strip-shaped frames 5 are uniformly and fixedly installed on the outer sides of the connection frames 4. In the middle of the inner bottom end of the strip-shaped frame 5, a positioning sleeve 6 is fixedly installed. A positioning support rod 7 is slidably installed inside the positioning sleeve 6, and one end of the positioning support rod 7 extends to the outside of the positioning sleeve 6. A connection block 8 is fixedly installed at the end of the positioning support rod 7 located outside the positioning sleeve 6. Four arc-shaped protection plates 9 are uniformly arranged on the outer side of the metal bellows 2, and one side of the connection block 8 away from the positioning support rod 7 is fixedly connected to one side of the arc-shaped protection plate 9 close to the metal bellows 2. A first spring 10 is fixedly installed at one end of the positioning support rod 7 located inside the positioning sleeve 6, and one end of the first spring 10 away from the positioning support rod 7 is fixedly connected to the inner wall of the positioning sleeve 6. Positioning sliders 18 are symmetrically and fixedly installed on the outer side of one end of the positioning support rod 7 located inside the positioning sleeve 6. Positioning chutes 19 are symmetrically formed on the inner wall of the positioning sleeve 6, and the positioning sliders 18 are slidably installed inside the positioning chutes 19. First connection shafts 11 are symmetrically and fixedly installed on one side of the connection block 8 away from the arc-shaped protection plate 9, and the positioning support rod 7 is located between the two first connection shafts 11. A connection bar 12 is rotatably installed on the first connection shaft 11. A second connection shaft 13 is rotatably installed at the end of the connection bar 12 away from the first connection shaft 11. Positioning blocks 14 are symmetrically and fixedly installed at the inner bottom end of the strip-shaped frame 5, and the positioning sleeve 6 is located between the two positioning blocks 14. Positioning cross bars 15 are fixedly installed on the sides of the two positioning blocks 14 away from each other, and one end of the positioning cross bar 15 away from the positioning block 14 is fixedly connected to the inner wall of the strip-shaped frame 5. A movable sleeve 16 is slidably installed on the outer side of the positioning cross bar 15, and the second connection shaft 13 is fixedly installed on the outer side of the movable sleeve 16. A second spring 17 is installed on the outer side of the movable sleeve 16 away from the positioning block 14 and on the outer side of the positioning cross bar 15, and the second spring 17 is sleeved on the outer side of the positioning cross bar 15.

[0022] During use, through the interaction of the flange 1, the metal bellows 2 and the impact-resistant component 3, it can enable the metal bellows compensator to achieve better impact resistance during use, avoid damage to the bellows section thereon, improve its service life, and thus facilitate better practicality. And through the interaction of the positioning slider 18 and the positioning chute 19, when the positioning support rod 7 moves inside the positioning sleeve 6, it can facilitate better stability, thereby ensuring that the impact-resistant component 3 can work stably.

[0023] Working principle: During operation, when the metal bellows compensator is impacted, the impact force acts on the arc-shaped protective plate 9, pushing the arc-shaped protective plate 9 to move. The arc-shaped protective plate 9 drives the connecting block 8 to move, and the connecting block 8 drives the positioning support rod 7 to slide inside the positioning sleeve 6. The positioning support rod 7 drives the positioning slider 18 to slide inside the positioning chute 19, which can ensure better stability when the positioning support rod 7 moves. At the same time, the movement of the positioning support rod 7 squeezes the first spring 10, causing the first spring 10 to undergo elastic deformation. At the same time, the connecting block 8 drives the first connecting shaft 11 to move, and the first connecting shaft 11 drives the connecting bar 12 to move. The connecting bar 12 pushes the movable sleeve 16 to slide outside the positioning cross bar 15 through the second connecting shaft 13. The movement of the movable sleeve 16 squeezes the second spring 17, causing the second spring 17 to undergo elastic deformation. Through the movement of the above structure, the kinetic energy generated by the impact force is dissipated, preventing the impact force from affecting the metal bellows compensator. After the impact force disappears, under the action of the rebound forces of the first spring 10 and the second spring 17, the structures on the impact-resistant component 3 are reset. In this way, during the use of the metal bellows compensator, it is convenient to achieve better impact resistance, avoid damage to the bellows section thereon, improve its service life, and thus facilitate achieving better practicality.
