Description

Technical Field

[0001] The utility model relates to the field of corrugated pipes, in particular to a directionally bent corrugated pipe. Background Art

[0002] A bellows is a tubular elastic sensitive element with a unique structure and properties. It is typically made up of foldable corrugated sheets connected along a specific direction, exhibiting excellent elastic properties. The thin walls of a bellows contribute to its high sensitivity.

[0003] Existing corrugated tubes have the following problems: first, the structural strength is insufficient. When the tube body is subjected to pressure from above or below, the tube body is easily deformed. Second, the tube body is uncertain and deformed unevenly during the bending process. Utility Model Content

[0004] The purpose of the utility model is to solve the above defects and provide a directional bending corrugated pipe.

[0005] The purpose of the present utility model is achieved in the following way: a directionally bent corrugated tube comprises a tube body, the upper surface of the tube body is provided with a plurality of first corrugated grooves, the lower surface of the tube body is provided with a plurality of second corrugated grooves, reinforcing ribs are provided between the first corrugated grooves and the second corrugated grooves, the upper inner wall of the tube body is provided with a plurality of first matching parts corresponding to the first corrugated grooves, the lower inner wall of the tube body is provided with a plurality of second matching parts corresponding to the second corrugated grooves, and the first matching parts and the second matching parts are both protruding upward.

[0006] Furthermore, the distances between two adjacent first corrugated grooves are consistent, and by providing a plurality of first corrugated grooves with consistent distances, the tube body can be bent in an upward direction.

[0007] Furthermore, the spacing between two adjacent second corrugated grooves is consistent, and by providing a plurality of second corrugated grooves with consistent spacing, the tube body can be directed to bend downward.

[0008] Furthermore, the spacing between two adjacent first matching parts is consistent. By providing a plurality of first matching parts with consistent spacing, when the tube body is oriented upward and bent, the bending angles between two adjacent first matching parts can be consistent.

[0009] Furthermore, the spacing between two adjacent second matching parts is consistent. By providing a plurality of second matching parts with consistent spacing, when the tube body is oriented downward and bent, the bending angles between two adjacent first matching parts can be consistent.

[0010] Furthermore, the tube body has a centrally-through structure.

[0011] Furthermore, there are two reinforcing ribs, which are respectively installed at the two ends of the tube body, and the reinforcing ribs are both installed inside the tube body. By arranging reinforcing ribs at both ends of the tube body, the tube body can only be bent up and down, and cannot be bent left and right.

[0012] The beneficial effects produced by the utility model are as follows:

[0013] By providing a first corrugated groove on the upper surface and a second corrugated groove on the lower surface, the tube body can have better directionality when bending. By providing reinforcing ribs between the first corrugated groove and the second corrugated groove, the overall structural strength of the tube body is enhanced. The reinforcing ribs can disperse the stress of the tube body when it is subjected to external pressure (such as lateral pressure, longitudinal pressure, etc.), and prevent the tube body from being easily deformed or damaged. The first matching portion of the upper inner wall of the tube body and the second matching portion of the lower inner wall are both raised upward. This structure helps to enhance the pressure resistance of the inside of the tube body. When there is fluid flowing in the tube and the pressure is high, these raised matching portions can resist the pressure of the fluid on the tube wall, reducing the occurrence of excessive deformation or even rupture of the tube wall due to internal pressure.

[0018] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0019] See also Figure 1-Figure 3The specifically implemented directional bending corrugated tube includes a tube body 1, which has a centrally-through structure. The upper surface of the tube body 1 is provided with a plurality of first corrugated grooves 2, and the lower surface of the tube body 1 is provided with a plurality of second corrugated grooves 3. The spacing between two adjacent first corrugated grooves 2 is consistent. By setting a plurality of first corrugated grooves 2 with consistent spacing, the tube body 1 can be directed to bend upward. The spacing between two adjacent second corrugated grooves 3 is consistent. By setting a plurality of second corrugated grooves 3 with consistent spacing, the tube body 1 can be directed to bend downward. When the tube body 1 needs to bend upward, the equal spacing of the first corrugated grooves 2 and the second corrugated grooves 3 acts as a guiding structure. Just like running on a track, they guide the tube body 1 to bend in the set direction, ensuring the regularity and directionality of the bending process.

[0020] A reinforcing rib 4 is provided between the first corrugated groove 2 and the second corrugated groove 3. There are two reinforcing ribs 4, which are respectively installed at the two ends of the tube body 1, and the reinforcing ribs 4 are installed inside the tube body 1. By providing the reinforcing ribs 4 at both ends of the tube body 1, the tube body 1 can only be directed to bend up and down, and cannot bend left and right. The method of providing the reinforcing ribs 4 inside the two ends of the tube body 1 has a great influence on the bending direction of the tube body 1. Due to the presence of the reinforcing ribs 4, the tube body 1 can only bend in the up and down direction, while the bending in the left and right directions will be restricted. This is like setting a framework for the bending of the tube body 1, which can only be deformed within the up and down dimension.

[0021] The upper inner wall of the tube body 1 is provided with a plurality of first mating portions 5 corresponding to the first corrugated grooves 2, and the lower inner wall of the tube body 1 is provided with a plurality of second mating portions 6 corresponding to the second corrugated grooves 3. Both the first mating portions 5 and the second mating portions 6 protrude upward. The spacing between two adjacent first mating portions 5 is consistent. By providing a plurality of first mating portions 5 with consistent spacing, the bending angles between two adjacent first mating portions 5 can be consistent when the tube body 1 is oriented upward and bent. When the tube body 1 is oriented upward and bent, since the spacing between two adjacent first mating portions 5 is consistent, the bending angles between them are also consistent. This ensures the uniformity of the angles of the tube body 1 during the upward bending process, making the bending process more stable and predictable.

[0022] The spacing between two adjacent second mating portions 6 is consistent. By providing a plurality of second mating portions 6 with consistent spacing, when the tube body 1 is oriented downward and bent, the bending angles between two adjacent first mating portions 5 are consistent. When the tube body 1 is oriented downward and bent, the consistent spacing between two adjacent second mating portions 6 also ensures that the bending angles between them are consistent, which also contributes to the stability and regularity of the tube body 1 when bending downward.

[0023] The above content is a further detailed description of the present invention in conjunction with specific further embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all of these should be considered as within the scope of protection of the present invention.
