Description

Technical Field

[0001] The invention relates to a rope ring and a ring forming method thereof, in particular to a self-locking knotless rope ring and a ring forming method thereof. Background Art

[0002] At present, the known operation of making a rope loop is an ordinary knotting process. However, since the rope loop is subjected to greater force when in use, the knotted part is more likely to slip and loosen, which greatly affects the stability and reliability of the rope loop. In addition, the mechanical properties of the rope are seriously lost after the knotting process, which also greatly reduces the safety of the rope loop when in use. In severe cases, it may cause huge loss of life and property.

[0003] The existing fishing nets use knotless nets, where the lines are woven and connected to each other, and the ends that need to be looped are bent into two ropes: Rope 1 with a free end and Rope 2 without a free end. The end of Rope 1 that is connected to Rope 2 is left empty for looping, and the remaining part is split into two large strands: Strand 1 and Strand 2. Strand 1 is passed through the middle of Rope 2, and then Strand 1 and Strand 2 are split into n small strands. Each time, a small strand is taken out from Strand 1 and Strand 2 respectively, and alternately woven into Rope 2 until all n small strands are woven into Rope 2. To ensure the stability of the rope loop, the length of the braided part is greater than or equal to the length of the looped part. The loop is knotless, which meets the requirements of not being easy to slip and loosen and having good stability, but the braiding process is time-consuming and labor-intensive, and in addition, before weaving, in order to facilitate the weaving of Rope 2, it is also mostly necessary to use auxiliary tools to drill holes. Summary of the invention

[0004] Aiming at the technical problem that it is time-consuming and labor-intensive to weave knotless rope loops for existing fishing nets, the present invention provides a time-saving and labor-saving self-locking knotless rope loop and a loop forming method thereof.

[0005] To this end, the present invention provides a method for forming a loop of a self-locking rope without a knot, comprising the following steps:

[0006] Step 1: Take the end of the rope to be looped, and divide it into two halves at a point on the rope to form a first small hole; the first small hole divides the rope into two parts, namely the first rope segment including the end and the second rope segment;

[0007] Step 2: Bend the first rope segment, insert the end portion into the first small hole, until the first rope segment passes through the first small hole, and tighten the first rope segment in a direction away from the second rope segment to flatten the first small hole to form a first eye ring;

[0008] Step 3: Take a point on the second rope segment and divide it into two halves to form a second small hole; the second small hole divides the second rope segment into two parts, namely the third rope segment and the fourth rope segment located between the first eye ring and the second small hole;

[0009] Step 4: Bend the first rope segment and the third rope segment, insert the ends into the second small hole, until the first rope segment and the third rope segment pass through the second small hole, and tighten the first rope segment and the third rope segment in a direction away from the fourth rope segment, flatten the second small hole, and form a second eyelet;

[0010] Step 5: Fold the third rope segment and insert it into the first eyelet, until the second eyelet and part of the fourth rope segment pass through the first eyelet to form a pseudo rope ring;

[0011] Step 6: Fold the third rope segment and insert it into the second eyelet to form a second pseudo rope loop;

[0012] Step 7: Pull the second pseudo rope ring and the fourth rope segment in opposite directions, and the two ends of the third rope segment are pulled out from the first eyelet and the second eyelet respectively, and the first small hole and the second small hole gradually approach each other to self-lock; at this time, the fourth rope segment is completely withdrawn from the first eyelet, the second pseudo rope ring becomes a rope ring, and a self-locking knotless rope ring is formed.

[0013] Preferably, the insertion direction in step 5 is opposite to the direction in which the end portion is inserted into the first small hole in step 2.

[0014] Preferably, the insertion direction in step 6 is the same as the direction in which the end portion is inserted into the second small hole in step 4.

[0015] Preferably, the first eyelet and the second eyelet are untied, the first eyelet is transformed back into a first small hole through which the fourth rope segment is passed, and the second eyelet is passed through a second small hole through which the third rope segment is passed.

[0016] Preferably, the distance between the second small hole and the first small hole in step 3 is determined according to the required circumference of the rope loop.

[0017] Preferably, the method further comprises step 8: making a small hole on the fourth rope segment, inserting the end portion into the hole and smoothing the hole.

[0018] The present invention also provides a self-locking knotless rope ring, comprising a first rope segment, a rope ring and a fourth rope segment, the tail end of the first rope segment is connected to the head end of the rope ring, and the tail end of the rope ring is connected to the head end of the fourth rope segment; a first small hole is provided at the tail end of the first rope segment, and the head end of the fourth rope segment is inserted into the first small hole; a second small hole is provided at the tail end of the rope ring, and the head end of the rope ring is inserted into the second small hole.

[0019] Preferably, the second small hole is located above the first small hole, and the second small hole and the first small hole are close to each other.

[0020] Preferably, the first rope segment, the rope ring and the fourth rope segment are an integral structure.

[0021] Preferably, the end is inserted into the fourth rope segment.

[0022] The beneficial effect of the present invention is that a self-locking knotless rope loop can be made with only one end of the rope through the method of the present invention, which is particularly suitable for self-locking knotless looping of longer ropes. There is no negative behavior of loosening the knot, and there is no mechanical loss behavior caused by knotting. It can not only effectively avoid the strength loss of the rope caused by knotting, but also ensure the stability and reliability of the rope loop. No auxiliary tools are required, the time spent is greatly shortened, and time and labor are saved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention will be further described below in conjunction with embodiments.

[0034] A method for forming a self-locking and knot-free loop of a cord, comprising the following steps:

[0035] Step 1: If Figure 1 As shown, take the end 1 of the rope body 2 to be looped, take a point on the rope body 2 to divide it into two halves, and form a first small hole 3. The first small hole 3 divides the rope body 2 into two parts, namely, a first rope segment 7 including the end 1 and a second rope segment 8;

[0036] Step 2: Bend the first rope segment 7 and insert the end 1 into the first small hole 3 (see Figure 1 ), until the first rope segment 7 passes through the first small hole 3, and the first rope segment 7 is tightened in the direction away from the second rope segment 8, the first small hole 3 is flattened, and the first hole 3 is formed to form a first eyelet 4 (see Figure 2 );

[0037] Step 3: If Figure 3 As shown, a point is taken on the second rope segment 8 and divided into two halves to form a second small hole 5. 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 located between the first eye ring 4 and the second small hole 5;

[0038] Step 4: Bend the first rope segment 7 and the third rope segment 9, and insert the end 1 into the second small hole 5 (see Figure 3 ), until the first rope segment 7 and the third rope segment 9 pass through the second small hole 5, and the first rope segment 7 and the third rope segment 9 are tightened in the direction away from the fourth rope segment 10, and the second small hole 5 is flattened to form a second eyelet 6 (see Figure 4 );

[0039] Step 5: Figure 5 As shown, the third rope segment 9 is folded and inserted into the first eyelet 4, until the second eyelet 6 and part of the fourth rope segment 10 pass through the first eyelet 4 to form a pseudo rope loop 11, and the insertion direction is opposite to the direction in which the end 1 is inserted into the first small hole 3 in step 2;

[0040] Step 6: Figure 6 As shown, 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 in which the end portion 1 is inserted into the second small hole 5 in step 4;

[0041] Step 7: Figure 6 As shown, the second pseudo rope ring 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 of the first eyelet 4 and the second eyelet 6 respectively; the first eyelet 4 and the second eyelet 6 are untied and turned back into the first small hole 3 through which the fourth rope segment 10 is passed and the second small hole 5 through which the third rope segment 9 is passed respectively; the first small hole 3 and the second small hole 5 gradually approach each other until they are self-locking, at which time the fourth rope segment 10 is completely withdrawn from the first eyelet 4, and the second pseudo rope ring 12 is turned into a rope ring 13 (see Figure 7 ), a 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, that is, the distance between the first small hole 3 and the second small hole 5.

[0042] Step 8: Make a small hole in the fourth rope segment 10, insert the end 1 into it and smooth it. (See Figure 8 )

[0043] When actually used as a trawl net, the distance between the first small hole 3 and the end 1 is usually 10-15 cm, and the circumference of the rope loop is 20-30 cm, that is, the distance between the first eyelet 4 and the second small hole 5 is usually 20-30 cm.

[0044] like Figure 8 As shown, the present invention also provides a self-locking knotless loop of a rope, comprising a first rope segment 7 with a free end 1, a rope ring 13 and a fourth rope segment 10, the tail end of the first rope segment 7 is connected to the head end of the rope ring 13, and the tail end of the rope ring 13 is connected to the head end of the fourth rope segment 10; a first small hole 3 is provided at the tail end of the first rope segment 7, and the head end of the fourth rope segment 10 is inserted into the first small hole 3; a second small hole 5 is provided at the tail end of the rope ring 13, and the head end of the rope ring 13 is inserted into the second small hole 5.

[0045] The second small hole 5 is located above the first small hole 3 , and the second small hole 5 and the first small hole 3 are close to each other.

[0046] The first rope segment 7 , the rope ring 13 and the fourth rope segment 10 are an integrated structure, and the end portion 1 is inserted into the fourth rope segment 10 .

[0047] Taking a 12-strand rope as an example, the time required to complete a rope loop using the existing method is about 8 minutes and 40 seconds, of which the rope splitting takes about 40 seconds, and each time two small strands are braided, it takes about 1 minute and 20 seconds. However, using the method of the present invention, the time required is 1 minute and 29 seconds, which is approximately equal to the time required to braid two small strands. For the same knotless loop, the looping method saves about 83% of the time compared with the existing method, greatly shortening the time cost and improving the braiding efficiency.

[0048] The method of the present invention can produce a self-locking knotless rope loop with only one end of the rope, which is particularly suitable for self-locking knotless looping of a relatively long rope. There is no negative behavior of loosening the knot, and there is no mechanical loss behavior caused by knotting. It can not only effectively avoid the strength loss of the rope caused by knotting, but also ensure the stability and reliability of the formed rope loop. No auxiliary tools are required, the time spent is greatly shortened, and time and labor are saved.

[0049] However, the above are only specific embodiments of the present invention and should not be used to limit the scope of implementation of the present invention. Therefore, the replacement of equivalent components, or equivalent changes and modifications made according to the scope of protection of the present invention should still fall within the scope covered by the claims of the present invention.
