Abstract

The invention relates to a mountain-climbing hook and a processing technology thereof. The mountain-climbing hook comprises a movable rod and a hook body with an articulation hole, wherein the outer peripheral surface of the hook body is encircled by an inner arc-shaped surface, an outer arc-shaped surface and two flat planes; the cross section abutting against the bottom of a gap and the cross section at the lower end of a mounting plate are intersected at a point A; when the movable rod is rotated, the upper end of the movable rod and the inner arc-shaped surface are intersected at a point B, the point A and the point B are connected to form a straight line Z, the shortest straight-line distance between a central point C of the cross section of the articulation hole and the outer arc-shaped surface is L3, and the shortest straight-line distance between the point C and the straight line Z is L4. The processing technology of the mountain-climbing hook is specifically as follows: smelting a well prepared alloy into an aluminum solution, degassing, refining, standing, skimming, and then casting into an aluminum alloy round cast bar; performing extrusion forming in a reverse direction; and performing heat treatment on a cast piece to obtain the mountain-climbing hook. The mountain-climbing hook provided by the invention has the advantages of relatively high tensile strength, corrosion resistance and fracture toughness, as well as long service life.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and relates to a climbing tool, in particular to a climbing hook. Background technique [0002] Mountaineering: refers to a sports activity in which athletes climb from low-altitude terrain to high-altitude peaks with bare hands or special equipment under specific requirements. Mountaineering can be divided into mountaineering expeditions (also known as alpine expeditions), competitive climbing (including rock climbing, ice climbing, etc.) and fitness mountaineering. Mountaineering tools are essential supplies for climbers. Mountaineering tools should adapt to the environmental conditions of mountaineering. In terms of design, material selection, materials, and production, they should be as light, strong, efficient, and multi-purpose as possible. Often going out for mountaineering and camping activities is of great benefit to the human body. From a medical point of view, it has direct ...
