Description

Technical Field

[0001] This utility model belongs to the field of safety equipment technology, and in particular relates to a detachable life-saving chair that is easy to transport. Background Technology

[0002] A life chair is a specialized piece of equipment installed at the edge of swimming pools, beaches, and scenic waters. It typically consists of a support frame, a seat, and safety handrails. It is used to allow lifeguards to observe and stand by from a high position so as to promptly detect and handle emergencies on the water. It is an important component of public water safety facilities.

[0003] However, existing lifesaving chairs still have some shortcomings. First, while lifesaving chairs are usually equipped with rescue poles and parasols, the chairs themselves often lack structures for mounting or storing these items. This necessitates separate brackets for the parasols, requiring them to be moved simultaneously with the chair, which is cumbersome and space-consuming. Rescue poles are typically placed against a wall or directly on the ground, affecting accessibility and increasing the risk of clutter and damage. Second, most existing lifesaving chairs use an L-shaped seat structure, with the corresponding frame also typically L-shaped. Bolt holes are usually placed at the front and corners of the frame for installation, but these corners are stress concentration areas; drilling holes weakens their strength, leading to deformation, cracks, or even breakage under prolonged use or uneven stress, posing a safety hazard. Furthermore, the frame structure of existing lifesaving chairs is usually welded, which adds inconvenience during handling and transportation. Utility Model Content
