Technical Field

[0001] The utility model relates to the technical field of anti-collision balls, in particular to an anti-collision ball for a corrugated pipe. Background Art

[0002] An anti-collision ball is an accessory used on a corrugated pipe to protect it. It is usually made of plastic or metal. It is usually connected and installed to the bellows through a clamping ring that matches the corrugations on the bellows, reducing the impact on the bellows while providing additional protection.

[0003] Since the spacing between the corrugations on the outer cylinder of the existing corrugated pipe is not the same, when installing an anti-collision ball on the corrugated pipe, it is necessary to additionally measure the spacing of the corrugations on the corrugated pipe and then select the anti-collision ball according to the size. At the same time, the existing anti-collision ball does not have the function of adjustment and adaptation, and the scope of application is small. Therefore, in order to solve the above technical problems, the utility model proposes an anti-collision ball for corrugated pipe. Utility Model Content

[0022] A movable groove 10 matching the guide block 6 is provided on the inner arc surface of the first hemisphere 1 near the guide block 6, and limit blocks 11 are installed at both ends of the movable groove 10. The limit blocks 11 match the movable groove 10, and both ends of the opposing screw 7 are rotatably connected to the limit blocks 11.

[0023] The first hemisphere 1 is provided with a mounting groove 12 matching the rotating gear disc 9 at a position near the rotating gear disc 9. The mounting groove 12 extends through toward the inner arc surface of the first hemisphere 1. A dial opening 13 is provided on the top surface of the first hemisphere 1 near the mounting groove 12.
