Description

A fastener with a safety latch Technical Field

[0001] This utility model relates to the field of fastener technology, and mainly to a fastener with a safety buckle. Background Technology

[0002] Fasteners are widely used as suspension and connection components in various fields such as industrial production, logistics and transportation, and home life. They are applied to scenarios such as hoisting goods, hanging tools, and organizing and storing. Traditional fasteners have a relatively simple structure, usually consisting of only a single S-shaped hook made of metal or plastic, which has some shortcomings in practical use.

[0003] On the one hand, existing fasteners often lack robust and reliable connections when linked to other components. For example, in situations requiring frequent loading and unloading or bearing significant tensile forces, connections can easily loosen or even detach, impacting work efficiency and potentially causing safety accidents, posing a threat to personnel and equipment. On the other hand, traditional S-hooks lack structural flexibility, making them difficult to adapt to different working environments and usage requirements. In some specialized installation scenarios, the fixed angle and position of the fastener prevent effective adjustments, hindering its compatibility with other components and limiting its application scope.

[0004] Furthermore, the installation and removal of existing fasteners are often cumbersome, requiring the use of specific tools, which increases both usage and time costs. Moreover, when fasteners are damaged and need replacement, their unreasonable structural design makes disassembly and replacement difficult, impacting equipment maintenance efficiency.

[0005] To address the problems existing in the prior art, this invention provides a fastener with a safety buckle. Through a unique S-shaped hook structure and a clever design of the plastic buckle, it effectively improves the connection stability and structural flexibility of the S-hook, while simplifying the installation and disassembly process. It has broad application prospects and practical value. Utility Model Content
