Embodiment 1

[0038] Please combine Figure 1 to Figure 4 , the present embodiment provides a bellows structure 100 including a multi-layer ring unit 10 and a multi-layer compensation unit 20 .

[0039] The ring unit 10 is a ring structure, and the ring structure can refer to the general setting of the current technology. The multi-layer ring units 10 are evenly arranged. Joints 15 are formed between the units 10 .

[0040] Please refer to figure 2 , the compensation unit 20 is arranged at the position of the joint part 15, that is, each compensation unit 20 is arranged between two ring units 10, and the ring units 10 are all in the shape of a semicircle, and the semicircle of the semicircle has an outer circumference corresponding to the outer peripheral contour The circle, the semi-circle here can be the case where the central angle of the arc of the outer peripheral contour is 180°, or the case where the central angle of the arc of the outer peripheral contour is less than or greater ...

Embodiment 2

[0057] This embodiment provides a corrugated pipe, which includes the above-mentioned corrugated pipe structure 100 and a straight pipe structure.

[0058] In the corrugated pipe, at least one end of the corrugated pipe structure 100 is connected to one end of the straight pipe structure to form a pipe.

[0059] In this embodiment, two ends of the bellows structure 100 in the bellows are respectively connected with two sections of straight pipes to form a pipeline.

Abstract

The invention provides a bellows structure and a bellows. The bellows structure comprises multiple layers of annular units and compensation units, the annular units and compensation units form tubularstructures, the annular units are uniformly arranged, a joint part is arranged between every two layers of annular units, and the compensation units are arranged on the joint parts; in an unbending state, projections of the peripheral contours of the annular units are coincided in the axial direction, and projections of the peripheral contours of the compensation units are coincided in the axialdirection; and in an bending state, the compensation units are located on the stretching face. The bellows comprises a bellows structure and a straight pipe structure, and one end of the bellows structure is connected with one end of the straight pipe structure to form a pipeline; and the bellows with the bellows structure has wider application range, larger stretching range and good economic andpractical values.

Description

technical field [0001] The present invention relates to the technical field of bellows, in particular to a bellows structure and a bellows. Background technique [0002] Pipelines are used in many industrial needs, and their main function is to transport items according to a certain route. [0003] However, in practical application scenarios, it is often inconvenient to use the pipe belt due to the limitation of the environmental space and the vibration of the mechanical work, so it is necessary to use a pipe with corrugations and can be bent at the position where the corrugations are set to overcome these problems. . [0004] Corrugated pipe is a kind of pipe that uses multi-layer foldable corrugated unit structure to achieve the purpose of stretching and compression. After the arrangement of each layer of unit structure, the outer peripheral contour of the pipe forms an undulating structure similar to corrugated. The outer circumference of each layer of unit structure Th...
