Detailed Description

The present invention will be further described with reference to the following examples.

As shown in fig. 7 and 8, a line self-locking knotless ring comprises a first rope segment 7 with a free end portion 1, a rope ring 13 and a fourth rope segment 10, wherein the tail end of the first rope segment 7 is connected with the head end of the rope ring 13, and the tail end of the rope ring 13 is connected with the head end of the fourth rope segment 10; the tail end of the first rope segment 7 is provided with a first small hole 3, and the head end of a fourth rope segment 10 penetrates through the first small hole 3; the tail end of the rope ring 13 is provided with a second small hole 5, and the head end of the rope ring 13 is threaded in the second small hole 5.

The second small hole 5 is positioned above the first small hole 3, and the second small hole 5 and the first small hole 3 are close to each other.

The first rope portion 7, the rope loop 13 and the fourth rope portion 10 are of an integral structure, and the end portion 1 is inserted into the fourth rope portion 10.

The ring forming method of the self-locking knotless ring of the utility model comprises the following steps:

step 1: as shown in fig. 1, an end portion 1 of one end of a rope body 2 to be looped is taken, and a part of the rope body 2 is divided into two parts to form a first small hole 3, wherein the first small hole 3 divides the rope body 2 into two parts, namely a first rope section 7 and a second rope section 8 which comprise the end portion 1;

step 2: bending the first rope segment 7, inserting the end part 1 into the first small hole 3 (see fig. 1) until the first rope segment 7 passes through the first small hole 3, tensioning the first rope segment 7 towards the direction far away from the second rope segment 8, and flattening the first small hole 3 to form a first eyelet 4 (see fig. 2);

and step 3: as shown in fig. 3, a part of the second rope segment 8 is divided into two parts to form a second small hole 5, and the second small hole 5 divides the second rope segment 8 into two parts, namely a third rope segment 9 and a fourth rope segment 10 which are respectively positioned between the first eyelet 4 and the second small hole 5;

and 4, step 4: bending the first rope segment 7 and the third rope segment 9, inserting the end part 1 into the second small hole 5 (see fig. 3) until the first rope segment 7 and the third rope segment 9 penetrate out of the second small hole 5, tensioning the first rope segment 7 and the third rope segment 9 in the direction far away from the fourth rope segment 10, and flattening the second small hole 5 to form a second eyelet 6 (see fig. 4);

and 5: as shown in fig. 5, the third rope segment 9 is folded and inserted into the first eyelet 4, until the second eyelet 6 and a part of the fourth rope segment 10 pass through the first eyelet 4, forming a pseudo rope loop 11, the insertion direction is opposite to the insertion direction of the end part 1 into the first small hole 3 in the step 2;

step 6: as shown in fig. 6, the third rope segment 9 is folded and inserted into the second eyelet 6 to form a second pseudo rope loop 12, and the insertion direction is the same as the direction of inserting the end part 1 into the second eyelet 5 in the step 4;

and 7: as shown in fig. 6, the second dummy rope loop 12 and the fourth rope segment 10 are pulled in opposite directions until the two ends of the third rope segment 9 are completely pulled out from the first eyelet 4 and the second eyelet 6 respectively; the first eyelet 4 and the second eyelet 6 are untied and respectively changed back to the first small hole 3 penetrated with the fourth rope segment 10 and the second small hole 5 penetrated with the third rope segment 9; the first small hole 3 and the second small hole 5 gradually approach to self-locking, at this time, the fourth rope segment 10 is completely withdrawn from the first eyelet 4, the second pseudo rope ring 12 is changed into a rope ring 13 (see fig. 7), the self-locking knotless rope ring is formed, and the circumference of the rope ring 13 is also the length of the third rope segment 9, namely the distance between the first small hole 3 and the second small hole 5.

And 8: a small hole is made in the fourth rope portion 10, into which the end 1 is inserted and flattened. (see FIG. 8)

When the fishing net is actually used, the distance between the first small hole 3 and the end part 1 is usually 10-15 cm, the circumference of the rope ring is 20-30 cm, and the distance between the first hole ring 4 and the second small hole 5 is usually 20-30 cm.

Taking 12 strands of rope as an example, the time required for completing a rope loop by adopting the existing method is about 8 minutes and 40 seconds, wherein the strand division takes about 40 seconds, and each two small strands take about 1 minute and 20 seconds after being woven. By adopting the method of the utility model, the required time is 1 minute and 29 seconds, which is approximately equal to the time required for weaving two small strands.
