The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] Please see Figures 1 to 6 The present invention preferably provides the following technical solution: an easily adjustable fire safety sling, comprising: a waist belt structure; a shoulder strap structure and a hip strap structure respectively assembled to the upper and lower parts of the waist belt structure, wherein the hip strap structure is provided with a buckle structure; the buckle structure includes a buckle body 119, the buckle body 119 including a plurality of concave and convex parts connected end to end, and the concave and convex parts on both sides are symmetrically distributed to form a first docking groove, and the concave and convex parts at both ends form a second docking groove; and a first hook assembly and a second hook assembly respectively provided on the waist belt structure and the shoulder strap structure, wherein the first hook assembly is connected to the first docking groove, and the second hook assembly and the hip strap structure are connected to the second docking groove, for quick assembly of the waist belt structure, the shoulder strap structure and the hip strap structure.

[0019] In this embodiment, the shoulder strap structure, waist belt structure, and hip belt structure, assembled sequentially from top to bottom, can form a safety harness structure through the connection of the buckle structure, such as... Figure 1 , 2 As shown in Figure 3, specifically: the buckle body 119 where the buckle structure is located is composed of several concave and convex parts connected end to end. The concave and convex parts on both sides are symmetrically distributed and form a first docking groove to be hooked with the first hook assembly on the waist belt structure. The concave and convex parts at both ends can form a second docking groove and can be hooked with the second hook assembly on the shoulder strap structure and the hip belt structure. Therefore, by adjusting the hooking or unhooking state of the first and second hook assemblies and the buckle body 119, the safety harness can be quickly put on and taken off, thereby significantly improving the convenience, efficiency and practicality of the safety harness. Furthermore, due to the structural characteristics of the ring buckle structure, the waist circumference and length of this safety harness can be flexibly adjusted by adjusting the buckle position of the first hook assembly and the first docking groove, thereby adapting to wearers of different body types. This design not only expands the applicability of this safety harness, but also significantly improves the ease of operation while ensuring the protective effect.
