Description

Technical Field

[0001] This disclosure relates to the field of bellows technology, and in particular to a bellows. Background Technology

[0002] A corrugated pipe, also known as a corrugated tube, metal corrugated pipe, or flexible metal pipe, is a component of a piping system used to transport fluids or gases, typically made of thin metal sheets. The characteristics of a corrugated pipe are its flexibility and pressure resistance; it can maintain its shape under certain internal or external pressure and can be bent and expanded. Currently, as a type of pipe with a corrugated structure, corrugated pipes are widely used in drainage, irrigation, pneumatic pipelines, hydraulic pipelines, and other fields due to their good flexibility and corrosion resistance.

[0003] Patent No. 2023231595605 discloses a metal corrugated pipe with a protective sleeve at one end. The protective sleeve has both a sealed and a sliding state. An adjustment device is provided on the protective sleeve, allowing it to switch between the sealed and sliding states. This patent utilizes a protective sleeve on the pipe body to protect the metal corrugated pipe in case of malfunction. While the metal corrugated pipe of this patent has good bending performance and flexibility, its corrugated structure makes its middle section highly susceptible to cracking from external forces. Utility Model Content

[0004] In view of the shortcomings or problems existing in the prior art, this disclosure provides a bellows with good mechanical properties.

[0005] The technical solution adopted by this disclosure to solve the above-mentioned technical problem is as follows: a corrugated pipe, including a support pipe, wherein a first waveform segment and a second waveform segment are respectively provided on both sides of the support pipe, and the support pipe is provided with a first inclined surface and a second inclined surface, wherein the first inclined surface is connected to the first waveform segment, and the second inclined surface is connected to the second waveform segment.

[0006] In a preferred embodiment, the support tube includes an annular structure, with the first inclined surface and the second inclined surface respectively disposed on both sides of the annular structure, and the angle between the first inclined surface and the annular structure being equal to the angle between the second inclined surface and the annular structure.

[0007] In a preferred embodiment, the first inclined surface is provided with a first connecting end and a second connecting end. The first connecting end is connected to the first waveform segment, and the second connecting end is connected to the ring structure. The diameter of the first connecting end is smaller than the diameter of the second connecting end.

[0008] In a preferred embodiment, the first waveform segment is connected to a first connector, the first connector having a first opening, the diameter of the first opening being smaller than the diameter of the second connector.

[0009] In a preferred embodiment, the second inclined surface is provided with a third connecting end and a fourth connecting end. The third connecting end is connected to the second waveform segment, and the fourth connecting end is connected to the ring structure. The diameter of the third connecting end is smaller than the diameter of the fourth connecting end.

[0010] In a preferred embodiment, the second waveform segment is connected to a second connector, the second connector having a second opening, the diameter of which is smaller than the diameter of the fourth connector.

[0011] In a preferred embodiment, the diameter of the first connecting end is equal to the diameter of the third connecting end; the diameter of the second connecting end is equal to the diameter of the fourth connecting end.

[0012] In a preferred embodiment, the wave height of the first waveform segment is 1.3-2.5 times the wave distance.

[0013] In a preferred embodiment, the wave height of the second waveform segment is 1.3-2.5 times the wave distance.

[0014] In a preferred embodiment, the number of ripples in the first waveform segment and the second waveform segment are equal.

[0015] In a preferred embodiment, the first connector is provided with a plurality of first mounting holes, and the second connector is provided with a plurality of second mounting holes.

[0016] Compared to existing products, the addition of a support tube prevents bending and stretching, while the first and second waveform segments can bend and stretch. This gives the corrugated pipe both flexibility and a certain degree of support, mitigating fatigue after repeated bending and stretching. During use, the central section of the corrugated pipe is most susceptible to cracking due to lack of support. This application places the support tube between the first and second waveform segments, strengthening the support in the middle of the corrugated pipe and effectively preventing cracks, thus extending its service life. The first and second inclined surfaces provide a buffer when fluid enters and exits the support tube, preventing tearing at the connection between the support tube and the first and second waveform segments due to fluid impact.

[0026] Please refer to Figures 1-3As shown, this application provides a corrugated pipe, which is generally a columnar structure and includes a support pipe 3. A first waveform segment 1 and a second waveform segment 2 are respectively provided on both sides of the support pipe 3. The number of corrugations of the first waveform segment 1 and the second waveform segment 2 are equal. The support pipe 3 is provided with a first inclined surface 31 and a second inclined surface 32. The first inclined surface 31 is connected to the first waveform segment 1, and the second inclined surface 32 is connected to the second waveform segment 2. This application incorporates a support pipe 3, which is inflexible and cannot be bent or extended, while the first waveform segment 1 and the second waveform segment 2 can bend and extend. This gives the corrugated pipe both flexibility and a certain degree of support, mitigating fatigue after repeated bending and extension. During use, the central section of the corrugated pipe is most susceptible to cracking due to lack of support. By placing the support pipe 3 between the first waveform segment 1 and the second waveform segment 2, this application strengthens the support in the middle of the corrugated pipe, effectively preventing cracks and extending its service life. The first inclined surface 31 and the second inclined surface 32 provide a buffer when fluid enters and exits the support pipe 3, preventing tearing at the connection between the support pipe 3 and the first and second waveform segments 1 and 2 due to fluid impact, thus making the corrugated pipe more durable. The corrugated pipe structure of this application is simple and has a long service life.

[0027] Please refer to the following: Figure 4As shown, specifically, the support pipe 3 includes an annular structure 33, with a first inclined surface 31 and a second inclined surface 32 respectively disposed on both sides of the annular structure 33. The angle between the first inclined surface 31 and the annular structure 33 is equal to the angle between the second inclined surface 32 and the annular structure 33. This arrangement ensures that the curvature of the connection between the first inclined surface 31 and the second inclined surface 32 and the annular structure 33 is consistent, making the buffering effect of the first inclined surface 31 and the second inclined surface 32 on the fluid essentially the same, preventing one of them from tearing due to excessive impact from the fluid. More specifically, the first inclined surface 31 is provided with a first connecting end 311 and a second connecting end 312. The first connecting end 311 is connected to the first waveform segment 1, and the second connecting end 312 is connected to the annular structure 33. The diameter of the first connecting end 311 is smaller than the diameter of the second connecting end 312; the diameter of the second connecting end 312 is smaller than the outer diameter of the first waveform segment 1, that is, the position of the annular structure 33 in the horizontal direction is inside the crest of the first waveform segment 1. The first waveform segment 1 is connected to a first connector 4, which has a first opening. The diameter of the first opening is smaller than the diameter of the second connector 312, and the diameter of the first opening is approximately equal to the inner diameter of the first waveform segment 1. Preferably, the wave height of the first waveform segment 1 is 1.3-2.5 times the wave pitch. This arrangement ensures that the first waveform segment 1 has sufficient load-bearing capacity while also providing good flexibility. When fluid enters the support pipe 3 from the first waveform segment 1, the flow rate decreases to a certain extent because the diameter of the first connecting end 311 is smaller than the diameter of the second connecting end 312. This prevents damage to the connection between the first waveform segment 1 and the support pipe 3 due to excessive fluid velocity. When fluid enters the first waveform segment 1 from the support pipe 3, the flow rate decreases as the second connecting end 312 is larger than the diameter of the first connecting end 311. A portion of the fluid enters the interior of the wave crest closest to the first inclined surface 31 of the first waveform segment 1. Since the diameters of both the second connecting end 312 and the first connecting end 311 are smaller than the outer diameter of the first waveform segment 1, the interior of the wave crest provides sufficient buffer space for the incoming fluid, thereby dispersing some of the fluid's impact force and preventing damage to the connection between the first waveform segment 1 and the support pipe 3 due to fluid impact.

[0028] Furthermore, the second inclined surface 32 is provided with a third connecting end 321 and a fourth connecting end 322. The third connecting end 321 is connected to the second waveform segment 2, and the fourth connecting end 322 is connected to the annular structure 33. The diameter of the third connecting end 321 is smaller than the diameter of the fourth connecting end 322. The second waveform segment 2 is connected to a second connecting head 5, which has a second opening. The diameter of the second opening is smaller than the diameter of the fourth connecting end 322, and the diameter of the second opening is approximately equal to the inner diameter of the second waveform segment 2. It can be understood that the diameter of the third connecting end 321 is equal to the diameter of the first connecting end 311, the diameter of the fourth connecting end 322 is equal to the diameter of the second connecting end 312, and the inner diameter of the second waveform segment 2 is equal to the inner diameter of the first waveform segment 1. When the fluid enters and exits the second waveform segment 2, the force situation at the connection between the second waveform segment 2 and the support pipe 3 is similar to that described above, and will not be repeated here. Preferably, the wave height of the second waveform segment 2 is 1.3-2.5 times the wave pitch. This design ensures that the second waveform segment 2 has sufficient load-bearing capacity while also maintaining good flexibility.

[0029] To facilitate the connection of the first connector 4 and the second connector 5 to other devices, the first connector 4 is provided with a number of first mounting holes 41, and the second connector 5 is provided with a number of second mounting holes 51.

The descriptions of the embodiments above are only for the purpose of helping to understand the present application and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to the present application without departing from the principles of the present application, and these improvements and modifications also fall within the protection scope of the claims of the present application.
