Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a power cable safety hook. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They are commonly used in urban underground power grids, power station lead-out lines, internal power supply for industrial and mining enterprises, and underwater transmission lines across rivers and seas. Safety hooks are a component used to limit and support power cables. They are a common tool used by circuit companies. The current installation hooks are generally implemented through threads, bolts, etc. during installation or assembly between components. Although this method is stable, it requires tools to assist during use and is slow to install.

[0003] The patent with publication number CN220022116U discloses a power cable safety hook, which realizes rapid assembly between two hooks by setting an installation device and a fixing device. No special tools are required for on-site assembly, which can improve assembly efficiency. However, the hook still has the same disadvantages as the existing hooks: when the cable is inside the hook, there is no structure above the hook to limit the cable position. During the cable laying and pulling process, the cable may fall off from the top of the hook; secondly, when the cable moves inside the hook, it will rub against the hook, causing the cable surface to be easily worn, so further improvement is needed.
