[0002] As a pipe with a special structure, bellows has good flexibility, corrosion resistance and sealing performance, and has been widely used in many fields. In the piping system, bellows are often used to compensate for the thermal expansion and contraction and displacement of the pipeline. For example, in thermal pipelines, temperature changes will cause the expansion and contraction of the pipeline. The bellows can absorb these deformations and reduce the stress of the pipeline and the impact on the surrounding structure. In the petroleum, chemical and other industries, bellows can be used to transport various corrosive media, such as acids, alkalis, oils, etc. Its corrosion resistance can ensure the safe transportation of the medium and extend the service life of the pipeline. In the field of mechanical manufacturing, bellows can be used as connectors or sealing elements. For example, in automobile engines, bellows are used to seal oil circuits and airways to prevent leakage.

[0021] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0022] The bellows bending structure with flexible bending adjustment according to an embodiment of the utility model will be described below with reference to the accompanying drawings.

[0023] like Figure 1-3 As shown, the bellows bending structure with flexible bending adjustment provided by the embodiment of the utility model includes a first connecting tube 1 and a second connecting tube 2. Two first connecting tubes 1 are provided, which are hingedly arranged at both ends of the second connecting tube 2 respectively, and a bendable tube 5 is arranged between the two first connecting tubes 1. Both ends of the first connecting tube 1 which are away from each other are provided with tightening seats 4 for clamping the bellows. The tightening seat 4 is provided with a tightening seat 3 on the outside, and the tightening seat 4 is connected to the first connecting tube 1 through the tightening seat 3. A sealing rubber sleeve 6 is arranged inside the tightening seat 4.

[0024] Specifically, the utility model directly connects the corrugated pipe through the bendable first connecting pipe 1 and the second connecting pipe 2, which can replace and protect the bent part of the corrugated pipe and prevent the damage of the corrugated pipe caused by long-term bending.

[0025] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, the bendable tube 5 passes through the first connecting tube 1 and the second connecting tube 2. The bendable tube 5 is made of a corrugated tube. The inner walls of the first connecting tube 1 and the second connecting tube 2 are both provided with plush pads. Adhesive seats 51 are provided at both ends of the bendable tube 5. The bendable tube 5 is respectively connected to the inner walls of the two first connecting tubes 1 through the adhesive seats 51.

[0026] Specifically, when in use, one end of the corrugated tube is passed through the sealing rubber sleeve 6, and then the tightening seat 41 is tightened and connected to the first connecting tube 1 by the tightening seat 3, and then the two symmetrical tightening seats 4 are pressed against each other by tightening the screws on the tightening seat 41 to hold the inner corrugated tube tightly. The first connecting tube 1 and the second connecting tube 2 provide external support and protection for the bendable tube 5, and the plush pad can prevent the bendable tube 5 from being squeezed and rubbed during the bending process.

[0027] In one embodiment of the present invention, Figure 2 As shown, the tightening seat 3 is threadedly connected with the first connecting tube 1, the inner circumferential wall of the tightening seat 3 facing away from the first connecting tube 1 is provided with a first wing ring 31, and the outer circumferential wall of one end of the tightening seat 4 is provided with a second wing ring 42, and the second wing ring 42 is located on the inner side of the first wing ring 31; there are two tightening seats 4 on the inner side of each tightening seat 3, and the two tightening seats 4 are both semi-circular ring structures, and the busbar edge of the tightening seat 4 is provided with a tightening seat 41, and a notch 43 is provided between the tightening seat 41 and the second wing ring 42.

[0028] Specifically, when the tightening seat 3 and the first connecting tube 1 are tightened with each other, the second wing ring 42 is located on the inner side of the first wing ring 31, and the first wing ring 31 clamps the second wing ring 42. At the same time, since a sealing ring is integrally provided at one end of the sealing rubber sleeve 6 close to the first connecting tube 1, the sealing ring is located on the outer side of the second wing ring 42, so that the end of the sealing rubber sleeve 6 and the first connecting tube 1 are clamped with each other and sealed.

[0029] like Figure 4 As shown, a gap 43 is set between the tightening seat 41 and the second wing ring 42. The gap 43 is used for the first wing ring 31 to pass through, so that the second wing ring 42 and the tightening seat 41 are separated from each other. On the one hand, the tightening seat 3 clamps the first wing ring 31 without affecting the two tightening seats 41 completely clamping each other, so that the sealing rubber sleeve 6 fully wraps the corrugated tube, achieving a good sealing effect.

[0030] In one embodiment of the present invention, Figure 1 As shown, a hinge 11 is provided at the connection between the first connecting tube 1 and the second connecting tube 2 to enable the first connecting tube 1 and the second connecting tube 2 to bend flexibly.

[0031] In order to clearly explain the above embodiments, refer to Figure 1-4 The specific working principle of the flexible bending and adjusting bellows bending structure of the utility model is as follows:

[0032] When in use, first pass one end of the corrugated tube through the sealing rubber sleeve 6, and then tighten the tightening seat 41 and the first connecting tube 1 through the tightening seat 3. When the tightening seat 3 and the first connecting tube 1 are tightened with each other, the first wing ring 31 clamps the second wing ring 42, and at the same time, the tightening seat 3 is tightened to make the end of the sealing rubber sleeve 6 sealed and connected with the first connecting tube 1.

[0033] Subsequently, by tightening the screws on the tightening seat 41, the two symmetrical tightening seats 4 are pressed against each other, the sealing rubber sleeve 6 on the inner side of the tightening seat 4 is tightened, and the sealing rubber sleeve 6 seals and hugs the outer wall of the inner corrugated tube. When the bending structure is bent, the first connecting tube 1 and the second connecting tube 2 provide external support and protection for the bendable tube 5. The plush pad can prevent the bendable tube 5 from being squeezed and rubbed during the bending process, and can provide alternative protection for the bent part of the corrugated tube to prevent damage caused by long-term bending of the corrugated tube.

[0034] In summary, the flexibly bendable and adjustable bellows bending structure of the embodiment of the utility model directly connects the bellows through the bendable first connecting tube and the second connecting tube components, which can replace and protect the bent part of the bellows and prevent damage caused by long-term bending of the bellows.

[0035] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and deform the above embodiments within the scope of the present invention.
