Description

Technical Field

[0001] This invention relates to the field of rope technology, and more particularly to a traction rope. Background Technology

[0002] In fields such as fisheries, mining, animal husbandry, vehicle towing and rescue, ropes are often used as towing ropes. People usually tie the ropes to connecting rings or hooks. However, tying the ropes directly to connecting rings or hooks is troublesome and can easily come loose, causing problems for people to use.

[0003] To make it easier for people to use, many traction rope products have loops at both ends, making it convenient for users to connect the traction rope to the connecting ring or hook. However, such products also have problems. The length of the traction rope is fixed. After directly connecting the two loops, the length of the rope in the middle is also fixed. This is often inconvenient for users, as they cannot adjust the rope length according to the usage scenario, resulting in poor applicability.

[0013] As an improvement of the present invention, the diameter D3 of the traction part and the diameter D2 of the second connecting neck are both smaller than the diameter D1 of the knot.

[0014] As an improvement of the present invention, the first end of the rope body is inserted into the rope loop at the first connection position, along the gap between two adjacent second strands, and the portion of the rope body between the first end of the rope body and the first connection position forms the first loop.

[0015] As an improvement of the present invention, the second end of the rope body is inserted into the rope loop at the second connection position, along the gap between two adjacent second strands, and the portion of the rope body between the second end of the rope body and the second connection position forms the second loop.

[0016] As an improvement of the present invention, the lasso assembly is made of a lasso rope body, which is woven from a plurality of third strands.

[0023] The beneficial effects of this invention are: through the above-described structure, users can select different connection methods according to their needs to adapt to different distance requirements between the traction device and the object being pulled. Specifically, when the distance between the traction device and the object being pulled is large, the user can connect the first and second loops to the traction connection points on the traction device and the object being pulled, such as hooks. In this case, the distance between the traction device and the object being pulled is approximately equivalent to the length of the rope body, i.e., L1 + L2. When the distance between the traction device and the object being pulled is short, the user can choose to connect either the first or second loop to one of the traction device and the object being pulled, connect the knot assembly to the lasso assembly to form a third loop, and connect the third loop to the other of the traction device and the object being pulled. In this case, the distance between the traction device and the object being pulled is approximately equivalent to the length L1 of the first rope unit or the length L2 of the second rope unit. When the distance between the traction device and the object being pulled is short, the user can choose to connect either the first or second loop to one of the traction device and the object being pulled, connect the knot assembly to the lasso assembly to form a third loop, and connect the third loop to the other of the traction device and the object being pulled.

When the distance is greater than L1 but less than L1+L2, the second loop can be connected to one of the traction device and the towed object, the third loop can be connected to the first loop to form a fourth loop, and the fourth loop can be connected to the other of the traction device and the towed object. In this case, the distance between the traction device and the towed object is approximately 0.5L1+L2. Alternatively, the first loop can be connected to one of the traction device and the towed object, the third loop can be connected to the second loop to form a fifth loop, and the fifth loop can be connected to the other of the traction device and the towed object. In this case, the distance between the traction device and the towed object is approximately L1+0.5L2. Thus, users can freely choose different connection methods according to their needs to adapt to the requirements of using traction ropes of different lengths. Attached Figure Description

[0033] Reference Figures 1 to 10 A traction rope, comprising: A rope body 100 is provided with a first connecting position 103, a second connecting position 104 and a third connecting position 105. A first loop 130 is provided at the first connecting position 103, and a second loop 140 is provided at the second connecting position 104. The first loop 130 and / or the second loop 140 are configured to connect to a traction connection. The distance between the end of the first loop 130 away from the third connecting position 105 and the third connecting position 105 is L1, and the distance between the end of the second loop 140 away from the third connecting position 105 and the third connecting position 105 is L2. L1 is greater than L2. Lasso assembly 200, the lasso assembly 200 being connected to the third connection position 105; A knot assembly 300 is connected to the third connection position 105 and is disposed adjacent to the lasso assembly 200. The knot assembly 300 and the lasso assembly 200 are releasably engaged to form a third loop 230. The third loop 230 is configured to connect to one of the traction connection, the first loop 130, and the second loop 140. When the third loop 230 is connected to the first loop 130, the first loop 130, the first rope unit 100a and the third loop 230 together form a fourth loop 233, which is configured to connect to the traction connection. When the third loop 230 is connected to the second loop 140, the second loop 140, the second rope unit 100b and the third loop 230 together form a fifth loop 234, which is configured to connect to the traction connection.

[0034] With the above-described structure, users can select different connection methods according to their needs to adapt to varying distance requirements between the traction device and the object being pulled. Specifically, when the distance between the traction device and the object being pulled is large, the user can connect the first set of rings 130 and the second set of rings 140 to the traction connection points on the traction device and the object being pulled, such as hooks. In this case, the distance between the traction device and the object being pulled is approximately equivalent to the length of the rope body 100, i.e., approximately L1 + L2. Figure 1 As shown; when the distance between the traction device and the object being pulled is short, the user can choose to connect one of the first loop 130 or the second loop 140 to the traction device and the object being pulled, connect the knot assembly 300 to the lasso assembly 200 to form a third loop 230, and connect the third loop 230 to the other of the traction device and the object being pulled. At this time, the distance between the traction device and the object being pulled is approximately equivalent to the length L1 of the first rope unit 100a or the length L2 of the second rope unit 100b, such as... Figure 4 As shown; when the distance between the traction device and the towed object is greater than L1 and less than L1+L2, the second ring 140 can be connected to one of the traction device and the towed object, and the third ring 230 can be connected to the first ring 130 to form a fourth ring 233. The fourth ring 233 is then connected to the other of the traction device and the towed object. At this time, the distance between the traction device and the towed object is approximately 0.5L1+L2. Figure 5As shown, alternatively, the first ring 130 can be connected to one of the traction device and the towed object, the third ring 230 can be connected to the second ring 140 to form a fifth ring 234, and the fifth ring 234 can be connected to the other of the traction device and the towed object. In this case, the distance between the traction device and the towed object is approximately L1 + 0.5L2. Figure 6 As shown, users can freely choose different connection methods to suit the needs of using traction ropes of different lengths.

[0035] In this embodiment, as Figure 3 As shown, the rope body 100 is woven from several strands 110, and the rope body 100 is generally cylindrical.

[0036] In this embodiment, the strands 110 include a plurality of first strands 11a made of a first material and a plurality of second strands 11b made of a second material. The first strands 11a are woven to form an inner core 111, and the second strands 11b are woven to form a rope loop 112, with the inner core 111 disposed on the rope loop 112. The first strands 11a are generally made of a high-tensile-strength material, such as at least one of high molecular weight polyethylene fiber, carbon fiber, nylon fiber, polyester fiber, polypropylene fiber, polyamide fiber, or aramid fiber. The second strands 11b are generally made of a high-abrasion-resistant material, such as at least one of ultra-high molecular weight polyethylene fiber, aramid fiber, polyetheretherketone fiber, polyphenylene sulfide fiber, carbon fiber, nylon fiber, polyester fiber, polypropylene fiber, or glass fiber. The rope loop 112 formed by the second strands 11b has strong abrasion resistance and can effectively protect the inner core 111. The inner core 111 formed by the first strands 11a has high tensile strength, allowing the product to withstand greater loads. The combination of the two balances strength, durability, and functionality.

[0037] In this embodiment, the ratio of L1 to L2 is between 1.5 and 1.9. Preferably, the ratio of L1 to L2 is 1.8. For example, if L1 is 2.5 meters and L2 is 1.5 meters, then different usage methods can be combined to form five usage lengths: 1.5 meters, 2.5 meters, 2.75 meters, 3.25 meters, and 4 meters. This makes the product more adaptable, applicable to more usage scenarios, and meets the diverse needs of users.

[0038] In this embodiment, as Figure 2As shown, the lasso assembly 200 includes a lasso loop 210 and a first connecting neck 220, and the knot assembly 300 includes a knot 310 and a second connecting neck 320. A first end 22a of the first connecting neck 220 is connected to the rope body 100, and a second end 22b of the first connecting neck 220 extends outward from the third connecting position 105 and is connected to the lasso loop 210. A first end 32a of the second connecting neck 320 is connected to the rope body 100, and a second end 32b of the second connecting neck 320 extends outward from the third connecting position 105 and is connected to the knot 310. The knot 310 is configured to releasably pass through the lasso loop 210. When in use, the knot 310 is passed through the lasso ring 210, and the lasso ring 210 abuts against the second end 32b of the second connecting neck 320 and the lower surface of the knot 310. The first connecting neck 220 is bent to form the third lasso ring 230. The connection and disassembly are very convenient, and the lasso ring 210 and the knot 310 are not easy to loosen, making the product safer to use.

[0039] In this embodiment, the circumference of the inner edge of the lasso loop 210 is approximately equal to the circumference of the outer edge of the knot 310. Therefore, when connecting the lasso assembly 200 and the knot assembly 300, the lasso loop 210 deforms, and its inner edge becomes approximately circular, just allowing the knot 310 to pass through. However, when the product is in use, due to the traction force acting on the product, the shape of the inner edge of the lasso loop 210 becomes a flat, elliptical shape. At this point, it is difficult for the knot 310 to pass through, effectively preventing loosening and making the product more stable in use.

[0040] In this embodiment, the knot assembly 300 further includes a traction part 330, which is connected to the knot 310 and extends outward in a direction away from the second connecting neck 320.

[0041] In this embodiment, as Figure 9 As shown, the diameter D3 of the traction part 330 and the diameter D2 of the second connecting neck 320 are both smaller than the diameter D1 of the knot 310. In use, the traction part 330 is first inserted along the lasso ring 210. Pulling the traction part 330 causes the outer surface of the knot 310 to press against the inner edge of the lasso ring 210, deforming the lasso ring 210 into a roughly annular structure. This makes it easier for the knot 310 to pass through the lasso ring 210, facilitating user assembly and use of the product. Furthermore, the smaller diameter D3 of the traction part 330 compared to the diameter D1 of the knot 310 makes it easier for the user to insert the traction part 330 into the lasso ring 210. The smaller diameter D2 of the second connecting neck 320 compared to the diameter D1 of the knot 310 allows the lasso ring 210 to stably abut against the second end 32b of the second connecting neck 320 and the lower surface of the knot 310.

[0042] In this embodiment, as Figure 7As shown, the first end 101 of the rope body 100 is inserted into the rope loop 112 at the first connecting position 103, along the gap between two adjacent second strands 11b. The portion of the rope body 100 between the first end 101 and the first connecting position 103 forms the first loop 130. During product manufacturing, the first end 101 of the rope body 100 can be inserted into the rope loop 112 at the first connecting position 103, along the gap between two adjacent second strands 11b. Then, a connecting wire harness can be used to fix the first end 101 of the rope body 100, forming an integral first loop 130. The rope body 100 inserted into the rope loop 112 makes full contact with the adjacent rope loop 112 and inner core 111. The friction and the binding force provided by the connecting wire harness make the first loop 130 structure more stable and stronger than a knotted structure. Furthermore, the product has no protruding knots, making it both aesthetically pleasing and convenient to use.

[0043] In this embodiment, as Figure 8 As shown, the second end 102 of the rope body 100 is inserted into the rope loop 112 at the second connecting position 104, along the gap between two adjacent second strands 11b. The portion of the rope body 100 between the second end 102 and the second connecting position 104 forms the second loop 140. During product manufacturing, the second end 102 of the rope body 100 can be inserted into the rope loop 112 at the second connecting position 104, along the gap between two adjacent second strands 11b. Then, a connecting wire harness can be used to fix the second end 102 of the rope body 100, forming an integral second loop 140. The rope body 100 inserted into the rope loop 112 makes full contact with the adjacent rope loop 112 and inner core 111. The friction and the binding force provided by the connecting wire harness make the second loop 140 structure more stable and stronger than a knotted structure. Furthermore, the product has no protruding knots, making it both aesthetically pleasing and convenient to use.

[0044] In this embodiment, as Figure 9 and Figure 10 As shown, the lasso assembly 200 is made of a lasso rope 240, which is woven from a plurality of third strands 24a. The lasso rope 240 has a first end 241, a second end 242 and a fourth connecting position 243. The first end 241 of the lasso rope 240 is inserted into the lasso rope 240 at the fourth connecting position 243, along the gap between two adjacent third strands 24a, to form the lasso loop 210.

[0045] In this embodiment, the second end 242 of the lasso rope 240 is inserted into the loop 112 and the inner core 111 at the third connection position 105, along the gap between two adjacent second strands 11b and the gap between two adjacent first strands 11a. The portion of the lasso rope 240 between the third connection position 105 and the fourth connection position 243 forms the first connecting neck 220. When manufacturing the product, the first end 241 of the lasso rope 240 can be inserted into the lasso rope 240 at the fourth connecting position 243, along the gap between two adjacent third strands 24a. Then, the first end 241 of the lasso rope 240 can be fixed with the connecting wire harness to form an integral lasso ring 210. The lasso rope 240 inserted into the lasso rope 240 is in full contact with the adjacent third strand 24a. The friction and the binding force provided by the connecting wire harness can make the structure of the lasso ring 210 more stable and stronger than the structure connected by a knot. Moreover, there are no protruding knots on the product surface, which is both beautiful and convenient to use. Then, the second end 242 of the lasso 240 is inserted into the loop 112 and the inner core 111 at the third connection position 105, along the gap between two adjacent second strands 11b and the gap between two adjacent first strands 11a. The lasso 240 inserted into the loop 112 and the inner core 111 rubs fully with the first strands 11a and the second strands 11b. The lasso 240 is firmly fixed by friction and the connecting wires, making the product structure more stable.

[0046] In this embodiment, as Figure 9 and Figure 10 As shown, the knot assembly 300 is made of a first knot rope body 340 and a second knot rope body 350. Both the first knot rope body 340 and the second knot rope body 350 are woven from a plurality of fourth strands 345. The first knot rope body 340 has a first end 341, a second end 342 and a fifth connecting position 343. The second knot rope body 350 has a first end 351 and a second end 352. The first knot rope body 340 and the second knot rope body 350 are knotted together to form the knot 310. The portion between the first end 341 of the first knot rope body 340 and the knot 310, and the portion between the first end 351 of the second knot rope body 350 and the knot 310, together form the traction part 330. By using the first knot rope body 340 and the second knot rope body 350 to tie a knot, a protruding knot 310 can be formed conveniently and quickly, resulting in high production efficiency and a stable structure.

[0047] In this embodiment, the second end 352 of the second knot rope body 350 is inserted into the first knot rope body 340 at the fifth connection position 343, along the gap between two adjacent fourth strands 345.

[0048] In this embodiment, the second end 342 of the first knot rope body 340 is inserted into the rope sleeve 112 and the inner core 111 at the third connection position 105, along the gap between two adjacent second strands 11b and the gap between two adjacent first strands 11a. The portion of the first knot rope body 340 and the portion of the second knot rope body 350 between the third connection position 105 and the fifth connection position 343 form the second connection neck 320. The second end 352 of the second knot rope body 350 is inserted into the first knot rope body 340. The second knot rope body 350 inside the first knot rope body 340 is in full contact with the fourth strand 345. The second end 352 of the second knot rope body 350 and the first knot rope body 340 are fixed together by friction and connecting wires to form an integral insertion part. Then, the second end 342 of the first knot rope body 340 and the insertion part are inserted into the rope sleeve 112 and the inner core 111. Similarly, the first knot rope body 340 and the second knot rope body 350 are stably connected to the rope body 100 by friction and connecting wires, thereby improving the strength of the product.

[0049] In this embodiment, the first end 341 of the first knot rope body 340 and the first end 351 of the second knot rope body 350 are provided with wrapping tape 360, which connects the first end 341 of the first knot rope body 340 and the first end 351 of the second knot rope body 350. Using wrapping tape 360 ​​to connect the first end 341 of the first knot rope body 340 and the first end 351 of the second knot rope body 350 makes it easier for the male user to insert the traction part 330 into the lasso ring 210, which is convenient to use. It can also restrain the multiple fourth strands 345 forming the first knot rope body 340 and the second knot rope body 350 to prevent them from loosening.

[0050] In this embodiment, the surface of the rope body 100 is coated with a coating, which is at least one of waterborne polyurethane, waterborne acrylic resin, waterborne polyester resin, waterborne silicone-containing resin, fluorinated resin, waterborne amino resin, waterborne alkyd resin, waterborne epoxy resin, waterborne phenolic resin, waterborne oil, waterborne polybutadiene, and waterborne hyperbranched polymer. Applying a polyurethane coating to the surface of the rope body 100 is an important functional optimization treatment of this solution. This coating forms a strong, continuous, and elastic protective film on the surface of the rope body. Its main functions are: first, significantly improving surface abrasion resistance, protecting the strands 110 from damage caused by friction and scratching during use, thereby extending the overall life of the traction rope; second, enhancing environmental protection, effectively blocking the corrosion of internal fibers by moisture, salt spray, ultraviolet rays, and some chemicals, broadening the applicability of the traction rope in harsh environments such as outdoor, marine, or industrial environments; third, improving surface performance and operability, making the surface of the traction rope smoother and reducing resistance during use, and possibly providing certain antistatic properties.
