[0037] The specific embodiments shown below are intended to be descriptions of various configurations of the subject technology of the present invention, and are not intended to represent the only configuration in which the subject technology of the present invention can be practiced. The specific embodiments include specific details intended to provide a thorough understanding of the subject technology of the present invention. However, it will be clear and obvious to those skilled in the art that the subject technology of the present invention is not limited to the specific details shown herein, and can be practiced without these specific details.

[0038] Reference Figures 1 to 6As shown, a corrugated pipe connection structure comprises a pipe body 1 and a connector 2, wherein two adjacent pipe bodies 1 are connected via the connector 2;

[0039] The tube body 1 is provided with a convex ring 11 which makes the outer wall of the tube body 1 form a corrugated shape, and the convex ring 11 and the tube body 1 are an integral structure;

[0040] The connector 2 includes a seat body 21, the seat body 21 is provided with a through hole 211, the through hole 211 is communicated with the tube body 1, the seat body 21 is slidably provided with a connecting plate 22, the connecting plate 22 slides along the diameter direction of the tube body 1, and the connecting plate 22 is provided with a positioning edge 221 extending between two adjacent convex rings 11;

[0041] The seat body 21 is also provided with a support tube 23 extending into the tube body 1, and the two ends of the support tube 23 are respectively connected to the tube body 1 and the through hole 211, and a positioning space is formed between the support tube 23 and the connecting plate 22; the support tube 23 is used to support the tube body 1 to prevent the tube body 1 from deformation.

[0042] A reinforcing rib 12 is provided in the convex ring 11 located in the positioning space;

[0043] The same pipe body 1 is positioned by two connecting plates 22 , and the connecting plates 22 that position the same pipe body 1 are connected by bolts 24 .

[0044] The seat body 21 is located between the two tube bodies 1, and the seat body 21 and the support tube 23 are an integrated structure. The through hole 211, the tube body 1, and the support tube 23 are coaxially arranged.

[0045] The cross-sectional shape of the seat body 21 can be circular or polygonal. When the tube body 1 needs to be positioned so that the tube body 1 is not easily rotated, the cross-sectional shape of the seat body 21 can be polygonal.

[0046] Reference Figures 1 to 6 As shown, in some embodiments, the seat body 21 is provided with a guide rib 212 , and the connecting plate 22 is provided with a guide groove 222 that cooperates with the guide rib 212 .

[0047] The width of the guide edge 212 on the side close to the seat body 21 is smaller than the width of the guide edge 212 on the side away from the seat body 21 . The guide edge 212 and the seat body 21 are an integrated structure.

[0048] The guide ribs 212 allow the connecting plate 22 to slide only along the diameter direction of the tube body 1 but not along the axial direction of the tube body 1 , so that the connecting plate 22 can effectively position the tube body 1 relative to the seat body 21 .

[0049] The cross-sectional shape of the guide rib 212 can be a trapezoid. There can be multiple guide ribs 212. The more guide ribs 212 there are, the higher the displacement accuracy of the connecting plate 22 is, and at the same time, the higher the positioning strength of the tube body 1 is. In other words, the connection strength between the tube body 1 and the seat body 21 in the axial direction is achieved by the cooperation of the guide ribs 212 and the guide grooves 222. Therefore, the more guide ribs 212 there are, the more contact surfaces there are at the connection between the connecting plate 22 and the seat body 21, and the connecting plate 22 is less likely to move along the axial direction of the seat body 21, that is, the connecting plate 22 and the guide ribs 212 are less likely to be damaged.

[0050] Reference Figures 1 to 6 As shown, in some embodiments, the connecting plate 22 is semicircular in shape, and the diameter of the connecting plate 22 matches the diameter of the tube body 1 , and there are at least two positioning edges 221 in the positioning space.

[0051] The two connecting plates 22 that are positioned on the same pipe body 1 form a cylindrical structure, and a portion of the pipe body 1 is located inside the cylindrical structure. The connecting plates 22 and the pipe body 1 have a larger contact area, so that stress concentration is less likely to occur on the pipe body 1 or the connecting plates 22, thereby improving the connection strength of the bellows connection structure and preventing the bellows from being damaged.

[0052] In some embodiments, the reinforcing rib 12 may be a metal rib, and the reinforcing rib 12 may be pre-placed in the convex ring 11. There may be one or more reinforcing ribs 12. The reinforcing rib 12 is used to assist in positioning, so that the convex ring 11 is not easily deformed, and the convex ring 11 is not easily misplaced relative to the pipe body 1, further improving the connection strength of the bellows connection structure.

[0053] In some embodiments, the positioning edge 221 includes a top surface in contact with the tube body 1 and side surfaces in contact with two adjacent convex rings 11 .

[0054] The larger the contact area between the positioning rib 221 and the tube body 1 and the convex ring 11, the less likely variable force concentration will occur on the positioning rib 221 and the tube body 1. Usually, the misalignment of the tube body 1 refers to the displacement of the tube body 1 along the tube body 1 and the axis direction, and this displacement will cause the connection failure of the tube body 1. When the tube body 1 is displaced along the axis direction, the convex ring 11 interferes with the positioning rib 221. The cooperation between the convex ring 11 and the positioning rib 221 can prevent the displacement of the tube body 1 along the axis direction.

[0055] The force generated by the displacement of the tube body 1 along the axial direction is concentrated on the convex ring 11 and the positioning edge 221. Therefore, the positioning edge 221 and the tube body 1 and the convex ring 11 should have a larger contact area to prevent variable force concentration from occurring on the tube body 1 and prevent the tube body 1 from being damaged.

[0056] The more the number of the positioning ribs 221 is, the larger the contact area between the positioning ribs 221 and the tube body 1 and the convex ring 11 is. Therefore, at least two positioning ribs 221 may be provided.

[0057] Reference Figures 1 to 6 As shown, in some embodiments, the cross-sectional shape of the convex ring 11 is semicircular, and the positioning edge 221 and the connecting plate 22 are an integral structure.

[0058] The cross-sectional shape of the convex ring 11 may also be a trapezoid that is narrow at the top and wide at the bottom, that is, the width of the convex ring 11 away from the tube should be smaller than the width of the contact point between the convex ring 11 and the tube body 1, so that the positioning edge 221 can be in complete contact with the tube body 1 and the convex ring 11, thereby increasing the contact area between the positioning edge 221 and the convex ring 11 and the tube body 1.

[0059] In some embodiments, the connecting plate 22 is provided with an extension plate 25 extending in the diameter direction, the extension plate 25 and the connecting plate 22 are an integral structure, and the extension plate 25 is provided with a screw hole for passing the bolt 24 .

[0060] Each of the connecting plates 22 is provided with at least two screw holes, each of which is provided with an independent bolt 24 , and the screw holes are evenly arranged along the axial direction of the tube body 1 .

[0061] Each connecting plate 22 is provided with two extension plates 25, which are arranged in the horizontal direction and protrude from the outer wall of the connecting plate 22 away from the tube body 1, so as to facilitate the assembly of the bolts 24. A reinforcing rib 12 may also be provided between the extension plate 25 and the connecting plate 22.

[0062] In some embodiments, the inner wall of the support tube 23 is flush with the inner wall of the tube body 1 .

[0063] The tube body 1 is provided with a matching hole 13 for accommodating the support tube 23 . The matching hole 13 is communicated with the tube body 1 , and the thickness of the matching hole 13 is equal to the thickness of the support tube 23 .

[0064] The support tube 23 and the seat body 21 can be an integrated structure, and the support tube 23 and the seat body 21 can be made of metal materials, and the connecting plate 22 can also be made of metal materials. The support tube 23, the seat body 21, and the connecting plate 22 should also be coated with an anti-rust layer.

[0065] The above introduces the subject technical solution of the utility model and the corresponding details. It can be understood that the above introduction is only some implementation plans of the subject technical solution of the utility model, and some details can be omitted during the specific implementation.

[0066] In addition, in some embodiments of the above utility model, multiple embodiments may be implemented in combination, and various combination schemes are not listed one by one due to space limitations. Those skilled in the art can freely combine and implement the above embodiments according to needs during specific implementation to obtain a better application experience.
