[0005] In the above-mentioned novel corrugated pipe, the ball seat and the shell are provided with a sealing ring for enhancing the sealing performance.

[0006] In the above-mentioned novel corrugated pipe, the installation groove two is arranged in a two-stage stepped structure, and the shell is provided with a convex ring on the inner wall at the communication position of the installation groove one and the installation groove two, which protrudes radially outward and abuts against the ball seat.

[0007] Compared with the prior art, the novel corrugated pipe can be adjusted radially by the universal adjusting unit, thereby reducing the bending degree of the corrugated pipe and prolonging the service life of the corrugated pipe. BRIEF DESCRIPTION OF DRAWINGS

[0008] Figure 1 is the cross-sectional structure schematic view of the novel corrugated pipe.

[0009] In the diagram, 1 is the front tube; 2 is the rear tube; 3 is the housing; 4 is the connecting rod; 5 is the limiting cover; and 6 is the ball seat. Detailed Implementation

[0010] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0011] like Figure 1 As shown, this novel corrugated pipe includes a corrugated pipe body, characterized in that the corrugated pipe body is composed of a front pipe 1 and a rear pipe 2, and the front pipe 1 and the rear pipe 2 are connected by a universal adjustment unit. The universal adjustment unit includes a housing 3, a hollow connecting rod 4 with a universal ball head, a limiting cover 5, and a ball seat 6. An axially inwardly recessed mounting groove for mounting the ball seat 6 is provided on the left end face of the housing 3. The ball seat 6 has a ball-receiving cavity for mounting the universal ball head and facilitating its movement. The outer end of the connecting rod 4 extends out of the housing 3 through the ball seat 6. The limiting cover 5 is located at and connected to the left end of the housing 3, limiting the position of the ball seat 6 within the housing 3. A semi-circular groove with an axial inward concavity is provided on the left end face of the 5. A through hole is provided on the limiting cover 5 for the outer end of the connecting rod 4 to extend out of the housing 3. The inner diameter of the through hole is larger than the outer diameter of the connecting rod 4. The front tube 1 is connected to the connecting rod 4. An axial inward concavity is provided on the right end face of the housing 3 for the installation of the rear tube 2 and is connected to the first installation groove. A dust cover connected to the left end of the housing 3 and also connected to the front tube 1 can be provided. A sealing ring with enhanced sealing performance is provided between the ball seat 6 and the housing 3. The second installation groove is set in a two-stage stepped structure. A radially outward protruding convex ring that abuts against the ball seat 6 is provided on the inner wall of the housing 3 at the connection between the first installation groove and the second installation groove.

[0012] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
