Double splay knot is to fold the rope in half, directly tie a splay knot and make a rope loop. Thread the splayed knot backwards and connect the rope with other things with double splayed knots. First tie a splayed knot in the middle of the rope, and the end of the rope passes through the end of the rope from the opposite direction along the knot, and then tighten it after adjustment.
1, use:
It is used for fixing and anti-skid. In the mountain world, whether it is a rope loop or a tether, the effect of the figure-eight knot is quite extraordinary. In addition to mountaineering, it is often used, and it is indispensable in all kinds of scenes in outdoor life.
2. Main features:
The double splayed knot has the advantages of strong endurance and firmness, and is very trustworthy in terms of safety; It is often used as a life-saving knot by mountaineers. However, the fly in the ointment is that it is difficult to adjust the size of the double-figure-eight knot, and it is difficult to untie the rope because of too heavy load, tight knot and damp.
3. Weave a splayed knot.
Introduction: Also known as climbing figure-eight knot or figure-eight hollow knot, it is firm and lasting. Usage: Tie the climbing rope to the protective gear, which can be used as a rope. Disadvantages: it is difficult to untie after falling.
4, continuous eight-character knot.
A continuous figure-of-eight knot is the same as a continuous single knot. Tie several figure-of-eight knots on the same rope. Because the figure-of-eight knot is relatively large, it can play a great role in outdoor games and emergency evacuation.
First, arrange the rope into several splays, then pass the end of the rope through all the rope loops, and a continuous splay knot is completed. The trick of continuous figure-eight knots is to start with the first loop that passes through the end.
1, flat knot: widely used in daily life to connect two ropes with the same thickness and material. The flat knot is mainly used when it is not necessary to untie or connect the two ends of the same rope after completion. In actual transportation, a single knot can be tied around the long rope, and a short rope head is used at the end of the knot to prevent the rope from loosening.
2. Double knot: commonly known as "trotter buckle", it is a double knot that ties the rope to the object. It can be quickly fastened to semi-closed objects and closed objects, and the more it is pulled, the tighter it is, which is simple and practical.
When the two ends of the rope are balanced, the double knot can play a great role. If the force is applied to only one end of the rope, you can tie a single knot around the long rope with a short rope head at the end of the knot to prevent the rope from loosening.
