In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0027] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0028] like Figure 1 and Figure 2 As shown, it includes a bellows 1, a flange 2 and a clamp 3. A blocking ring 4 is arranged on the outer side of the end of the bellows 1 in the length direction. An annular clamping portion 11 is provided on the outer wall of the bellows 1. The clamping portion 11 surrounds the outer wall of the bellows 1. The clamping portion 11 is connected to the blocking ring 4, and the blocking ring 4 extends outward in a divergent manner.

[0029] The flange 2 includes an integrally formed ring disk 21 and a hollow tube 22. The ring disk 21 is fitted with the blocking ring 4. The ring disk 21 and the blocking ring 4 are clamped by the clamp 3. The bellows 1 has a raised corrugated ring 12. The clamping portion 11 is located between the corrugated ring 12 and the blocking ring 4. Part of the structure of the clamp 3 is located between the corrugated ring 12 and the blocking ring 4. The clamping portion 11 serves to avoid the clamp 3.

[0030] The hollow tube 22 is communicated with the inside of the corrugated tube 1 , and the hollow tube 22 is externally connected to other equipment. The corrugated tube 1 is connected to other equipment through the clamp 3 and the flange 2 .

[0031] A protective wall 5 is provided on the outer periphery of the blocking ring 4 , and the extending direction of the protective wall 5 is consistent with the extending direction of the clamping portion 11 . Because the annular disk 21 and the blocking ring 4 are arranged in close contact, the protective wall 5 can protect the connection between the annular disk 21 and the blocking ring 4 .

[0032] The protective wall 5 wraps around the outer wall of the ring disk 21 , so as to prevent the connection between the ring disk 21 and the blocking ring 4 from backflowing liquid or gas, and the protective wall 5 has a reinforcing effect on the ring disk 21 .

[0033] like Figure 3 and Figure 4 As shown, the hoop 3 includes a hoop ring 31 with an arc and a screw 32. The first connecting column 311 and the second connecting column 312 are respectively provided at both ends of the hoop ring 31. The two ends of the hoop ring 31 are on the same circumference. The first connecting column 311 and the second connecting column 312 are threadedly connected by the screw 32. By rotating the screw 32, the hoop ring 31 has elasticity, which can make the first connecting column 311 and the second connecting column 312 approach or move away from each other, and the hoop ring 31 shrinks or expands accordingly.

[0034] The clamp 3 also includes a snap ring 33, which is arranged in close contact with the inner wall of the clamp ring 31. The snap ring 33 can move in close contact with the inner wall of the clamp ring 31. The snap ring 33 has an integrally formed first side wall 331, a second side wall 332 and a bottom wall 333. The first side wall 331 and the second side wall 332 are respectively located on both sides of the bottom wall 333. A groove 334 is formed between the first side wall 331 and the second side wall 332. The ring disk 21 and the blocking ring 4 are clamped in the groove 334. The ring disk 21 and the blocking ring 4 are clamped together by the first side wall 331 and the second side wall 332.

[0035] The multiple-section clamping rings 33 are arranged at intervals on the inner wall of the hoop 31 , so that when the first connecting column 311 and the second connecting column 312 are close to each other, the hoop 31 contracts, and the adjacent clamping rings 33 are close to each other, which facilitates the clamping of the clamp 3 .

[0036] The first side wall 331 has a first flange 335, and the second side wall 332 has a second flange 336. The first flange 335 and the second flange 336 are arranged back to back, and the extension directions of the first flange 335 and the second flange 336 are opposite. For ring disks 21 and blocking rings 4 of different sizes, the first side wall 331 can abut against the clamping portion 11, and the second side wall 332 can abut against the hollow tube 22.

[0037] To prevent the first side wall 331 and the second side wall 332 from being damaged, the first flange 335 can be abutted against the clamping portion 11 , and the second flange 336 can be abutted against the outer wall of the hollow tube 22 , thereby increasing the force-bearing area of ​​the first side wall 331 and the second side wall 332 .

[0038] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
