Description

Folding walking stick

Technical Field

The invention relates to the field of outdoor exercise auxiliary equipment, in particular to a foldable walking stick.

Background

A walking stick (also called a alpenstock) refers to an auxiliary apparatus used when engaging in outdoor sports such as outdoor hiking, skiing, walking, cross-country mountain running, mountain climbing, and the like. The reasonable walking stick can support people on steep and rugged mountains, snowfields and paved roads, so that the body of the people is kept balanced, the load on the human body is shared, the burden of knees and legs is reduced, the sports injury is reduced, and the sports time is prolonged. The application of the walking stick in outdoor sports is more and more extensive, and basically, the walking stick is a walking stick in outdoor sports.

The walking sticks can be divided into walking sticks, alpenstock, ski sticks, hiking sticks, cross-country running sticks and the like according to the movement function; according to the number of the joints, the walking stick can be divided into a single joint, a double joint, a three joint (Z type), a four joint (M type) … 7 joint (blind stick) and the like.

For a multi-section cane, the multi-section cane usually has an inner cable locking system, and the two sections of the cane are held to perform rope tightening in different directions, so that splicing and fixing of two adjacent sections of cane rods are realized. The inner cable locking system mainly comprises three structural forms: 1. the structure form is tightened by the self elasticity of the rope; 2. the pull rope is fixed by a knot; 3. the drawing rope is fixed by the buckle elastic sheet. However, these inner wire locking systems have the following disadvantages: 1. the rope in the crutch rod needs to be pulled forcefully during adjustment each time, the pulling and unlocking are inconvenient, and sometimes the rope needs to be wound on a hand in order to pull the rope fastening, so that the skin is easily injured; 2. the walking stick is usually operated by two hands at the same time, the walking stick is held by one hand and pulled by the other hand, particularly when the walking stick is operated by wearing gloves, the operation is not flexible and quick enough, and the gloves are usually required to be taken down for locking the walking stick, so that the risk of frostbite is easily caused in an extremely cold environment; 3. as the material ages, the elastic force of the elastic cord may fade quickly, causing the cane to be unable to lock completely, and possibly failing to retract during use.
