Description

Technical Field

[0001] The utility model belongs to the field of anti-slip hooks, in particular to a portable anti-slip hook for climbing transmission line iron towers. Background Art

[0002] Climbing hooks usually refer to hooks or protective equipment used on rock walls or in rock climbing. Their main uses include: fixing climbing equipment, hanging equipment, etc. to improve safety during climbing. In some climbing work, hooks can be used as protection points to help users reduce the risk of falling.

[0003] When the existing anti-drop hook is used for tower climbing, since the lower end of the general hook is often equipped with a secondary rope, and the upper end hook is hung on the user's body, when using it, it is often necessary to first remove the hook from the user's body and then hang it on the main rope, which is very inconvenient. In addition, the surface of the general hook is relatively smooth, and there is a possibility of accidental slipping when used at high altitude.

[0004] Therefore, in order to solve the problem that the above-mentioned anti-slip hook is cumbersome to use and difficult to carry when used for climbing towers, a portable anti-slip hook for climbing transmission line towers is developed. By adding a snap-type installation structure, a pin structure and a double fixing structure to the anti-slip hook, the convenience of the hook when in use can be effectively improved, the safety of the hook when in use can be improved, and the portability of the hook can be further improved.
