Description

1 TOW ROPE TECHNICAL FIELD [0001] The present disclosure relates to the technical field of ropes, in particular to a tow rope. BACKGROUND [0002] In fields such as fisheries, mining, animal husbandry, vehicle towing, and rescue operations, ropes or cables are frequently employed as tow elements. Conventionally, users secure a rope by directly knotting or lashing it around a connecting ring or a connecting hook. However, such direct attachment is not only cumbersome and time-consuming but also prone to loosening or detachment during use, thereby causing inconvenience and potential safety hazards to the user. [0003] To facilitate easier connection, many existing tow rope products incorporate preformed loops (splices or grommets) at both ends, enabling the user to readily attach the tow rope to a connecting ring or hook. Nevertheless, such conventional products suffer from a significant limitation: the length of the rope is fixed. Once the two loops are respectively connected to the towing device and the object to be towed, the effective length of the rope extending therebetween remains constant and cannot be adjusted. In many practical scenarios, this fixed length proves inconvenient, as it fails to accommodate varying distances between the towing device and the towed object, resulting in poor adaptability and limited applicability. SUMMARY [0004] To overcome the shortcomings of the prior art, the present disclosure provides a tow rope having a simple structure and capable of meeting diverse user requirements [0005] To realize the above objective, the present disclosure provides a tow rope, including: a rope main body having a first crossing point, a second crossing point, and a third crossing point; a first loop is formed at and connected to the first crossing point, a second loop is formed at and connected to the second crossing point; wherein at least one of the first loop and the second loop is configured to be secured to one of an object to be towed and a towing device; wherein a distance between an end of the first loop remote from the third crossing point and 2 the third crossing point is L1, and a distance between an end of the second loop remote from the third crossing point and the third crossing point is L2, with L1 > L2; a ring assembly connected to the third crossing point; a knot assembly connected to the third crossing point and arranged adjacent to the ring assembly; wherein the knot assembly is releasably engaged with the ring assembly to form a third loop, and the third loop is configured to selectively connect to another one of the object to be towed and the towing device, the first loop, or the second loop; wherein, when the third loop is connected to the first loop, the first loop, a first rope segment of the rope main body, and the third loop together enclose and form a fourth loop, and wherein the fourth loop is configured to be secured to another one of the object to be towed and the towing device; wherein, when the third loop is connected to the second loop, the second loop, a second rope segment of the rope main body, and the third loop together enclose and form a fifth loop, and wherein the fifth loop is configured to be secured to another one of the object to be towed and the towing device. [0006] Furthermore, the rope main body is formed by braiding a plurality of strands, and the rope main body is substantially cylindrical in shape. [0007] Furthermore, the plurality of strands comprises a plurality of first strands made of a first material and a plurality of second strands made of a second material; wherein the plurality of first strands is braided to form an inner core, the plurality of second strands is braided to form a sheath, and the inner core is disposed inside the sheath. [0008] Furthermore, a ratio of L1 to L2 is in a range of 1.5 to 1.9. [0009] Furthermore, the ring assembly comprises an eye loop and a first neck connection part, the knot assembly comprises a knot and a second neck connection part; wherein a first end of the first neck connection part is connected to the rope main body, and a second end of the first neck connection part extends outwardly from the third crossing point and is connected to the eye loop; wherein a first end of the second neck connection part is connected to the rope main body, and a second end of the second neck connection part extends outwardly from the third crossing point and is connected to the knot; wherein the knot is configured to be releasably passed through the eye loop. [0010] Furthermore, an inner perimeter of the eye loop is approximately equal to an outer perimeter of the knot. 3 [0011] Furthermore, the knot assembly further comprises a pulling portion, and the pulling portion is connected to the knot and extends outwardly in a direction away from the second neck connection part. [0012] Furthermore, a diameter of the pulling portion and a diameter of the second neck connection part are both smaller than a diameter of the knot. [
