Description

Technical Field

[0001] The utility model relates to the technical field of umbrella accessories, in particular to a novel umbrella pole sliding sleeve. Background Art

[0002] In an umbrella frame, a movable cover located on the umbrella pole is usually called a "slider" or "sliding cover".

[0003] These sliders are one of the key components of the umbrella frame, they work with the umbrella pole to allow the umbrella frame to be smoothly opened or closed when needed. Sliders are usually made of metal or plastic, with an inner diameter that matches the umbrella pole to ensure that they can fit tightly on the umbrella pole and slide along it.

[0004] When the umbrella is opened, the support rods of the umbrella frame can be extended outward along the umbrella pole by pushing or pulling the sliders, thereby unfolding the umbrella cover. When the umbrella needs to be folded, the sliders will slide down along the umbrella pole to close the support rods, thereby folding the entire umbrella frame and umbrella cover.

[0005] The sliding sleeve is generally provided with round holes, through which the support rod can be firmly fixed on the sliding sleeve and can be expanded or retracted as the sliding sleeve moves on the umbrella pole. This connection method ensures the stability and reliability of the umbrella frame.

[0006] However, due to its circular geometric shape, the edge of the circular hole is more likely to experience stress concentration when subjected to external force, resulting in reduced overall stability of the sliding sleeve. Due to shape and size limitations, the circular hole may easily generate more friction and resistance during the sliding process. Therefore, a new umbrella pole sliding sleeve structure is proposed to solve the above problems. Utility Model Content
