[0002] In a children's playground, there is a problem of diameter change in the conveying pipeline of ocean balls. For example, ocean balls with an outer diameter of 80 mm are conveyed from a pipeline with a diameter of 90 mm to a pipeline with a diameter of 100 mm. The existing pipeline connection methods are mostly internal insertion type diameter change, directly inserting a pipeline with a diameter of 90 mm into a pipeline with a diameter of 100 mm. When using ocean balls in the pipeline, due to the influence of pipeline air flow, the ocean balls may rotate in the pipeline before and after the diameter change, affecting the normal use of the ocean balls.

[0004] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

[0005] A pipeline diameter-changing device for preventing the rotation of ocean balls, including an annular connecting part, an upper connecting sleeve arranged at the top of the annular connecting part, and a lower connecting sleeve arranged at the bottom of the annular connecting part. The axis lines of the annular connecting part, the upper connecting sleeve, and the lower connecting sleeve are collinear. The inner diameter of the upper connecting sleeve is larger than the inner diameter of the lower connecting sleeve. A rotation-preventing strip is arranged on the inner wall of the lower connecting sleeve. The pipeline before diameter change is inserted into the upper connecting sleeve, and the lower connecting sleeve is inserted into the pipeline after diameter change.
