Description

Towline and winch with same

Technical Field

The invention belongs to the technical field of ropes, and particularly relates to a towing rope and a winch with the same.

Background

Towlines are widely used for traction and rescue of vehicles or boats. In the related art, the two ends of the towing rope are respectively provided with the eye, and when the vehicle towing hook is used, the eye at one end of the towing rope can be sleeved on the towing hook of the vehicle, and the eye at the other end of the towing rope can be sleeved on the towing hook of the other vehicle. However, such a towing rope has a problem of inconvenient use, for example, when a vehicle uses the towing rope for self-rescue, a loop eye at one end of the towing rope is sleeved on a towing hook of the vehicle, the other end of the towing rope needs to be connected with other fixedly connected objects such as trees or fixing piles, and the loop eye at the other end of the towing rope cannot be directly sleeved on the trees or the fixing piles, so that the use is inconvenient. The related art also proposes a tow rope having a eyelet formed at one end and a knot (generally referred to as a diamond knot) formed at the other end. When the novel combined type towing rope is used, the knot at one end of the towing rope is buckled with the eye at the other end of the towing rope, so that the towing rope is integrally formed into a ring shape, but the problem that the eye and the knot are inconvenient to connect and the towing rope is inconvenient to connect with other objects exists particularly when the towing rope is long, in addition, the length of the towing rope is reduced due to the fact that the one end of the towing rope is connected with the other end of the towing rope, the use convenience is reduced, and the problem of inconvenience still exists due to the fact that the towing rope is integrally formed into the ring shape.

The embodiments described below by referring to the drawings are illustrative and intended to explain the present invention and should not be construed as limiting the invention.

A tow rope 100 according to an embodiment of the present invention is described below with reference to fig. 1-11. As shown in fig. 1, the tow rope 100 includes a rope body 11 and a first diamond knot 21. The rope 11 has a first end and a second end in its length direction, the second end of the rope 11 not being shown in fig. 1. The first end of the rope 11 is provided with a first eye 111, the first diamond knot 21 is connected with the rope 11, and the connection position of the first diamond knot 21 and the rope 11 is adjacent to the first eye 111. The first diamond 21 and the first eyelet 111 may be snapped onto to form a first eyelet 22, as shown in fig. 2, and the first diamond 21 and the first eyelet 111 may be separated, as shown in fig. 1.

Wherein the "first diamond knot 21 is connected to the string body 11" includes that the first diamond knot 11 is directly provided on the string body 11, and the first diamond knot 11 is connected to the string body 11 through a connecting string body of a certain length. In the embodiment shown in fig. 1 and 2, the first diamond knot 11 is connected to the string 11 by a first connecting string 23.

"the connection position of the first diamond knot 21 and the string 11 is adjacent to the first eye 111" means: in the case where the first diamond knot 21 is directly provided on the string body 11, the distance of the first diamond knot 21 from the first end of the string body 11 is smaller than the distance of the first diamond knot 21 from the second end of the string body 11; in the case where the first diamond knot 21 is connected to the string 11 through the first connection string 23, the distance between the connection location of the first connection string 23 to the string 11 and the first end of the string 1 is smaller than the distance between the connection location and the second end of the string 1. Preferably, the length of the first connection string 23 is smaller than the distance between the connection location and the first eye 111. For example, the distance between the connection location and the first eye 111 is preferably 200-400 mm, and the length of the first connection string 23 is preferably 50-150 mm. The length of the string 11 is not particularly limited, and may be, for example, 3 meters to 50 meters.

Referring to fig. 2, the first diamond knot 21 is fastened to the first eyelet 111 means that the first diamond knot 21 passes through the first eyelet 111 and is caught to form a ring-shaped first eyelet 22 at the first end of the string body 11, and the first eyelet 22 may be fitted over the connection object. Referring to fig. 1, the first diamond knot 21 is separated from the first eyelet 111, which means that the first diamond knot 21 is pulled out of the first eyelet 111, and the first eyelet 22 is not formed at the first end of the string 11.

According to the towing rope provided by the embodiment of the invention, the first ring hole is arranged at the first end of the rope body, the first diamond knot is arranged adjacent to the first end of the rope body, the first diamond knot is buckled with or separated from the first ring hole, and the first button hole is formed when the first diamond knot is buckled with the first ring hole. In addition, as the first diamond knot is adjacent to the first eye, the convenience of buckling and separating operations between the first diamond knot and the first eye is not affected by the length of the rope body, and the length of the towing rope is not shortened due to the formation of the first eye, so that the towing rope provided by the embodiment of the invention has greatly improved use convenience compared with the towing rope in the related art.

When the traction object is used, if the traction object has an existing towing hook or shackle (such as a vehicle), the first eye can be directly sleeved on the towing hook or shackle, namely, the traction object is directly sleeved and connected by the first eye, and if the traction object main body has no connection point (such as a tree or a fixed pile) which can be directly sleeved, the first eye can be used for connecting the frame of the traction object main body. Therefore, the towing rope provided by the embodiment of the invention has the advantages of multiple functions, strong universality and convenience in use.

The towing rope of the embodiment of the invention can also be a safe and high-strength multifunctional trailer extension integrated rope.

Alternatively, the rope 11 is a fiber rope. The rope 11 comprises an ultra-high molecular polyethylene fiber rope core, an ultra-high molecular polyethylene tightly woven sheath coating the rope core and a polyurethane coating coated outside the sheath, and has the advantages of wear resistance, light weight, chemical corrosion resistance and ultraviolet resistance.

In some embodiments, the first eyelet 111 is formed by splicing a first end of the rope 11. "splicing" refers to the joining of two or more lengths of rope by braiding. As an example, as shown in fig. 1 and 2, the first end of the string body 11 is connected to the string body 11 by twisting to form a ring-shaped first eyelet 111. The first eye 111 is formed at the first end of the rope body 11 in a splicing manner, namely, the rope body section forming the first eye 111 is integrated with other parts of the rope body 11, the integrity of the towing rope 100 is stronger, meanwhile, the splicing position has strong connection strength, the connection position is not easy to break, and the towing rope 100 has stronger reliability.

In some embodiments, the first diamond knot 21 is directly connected to the string 11, i.e., the string 11 is directly provided with the first diamond knot 21 adjacent to its first end, the first diamond knot 21 being against the string 11.

Preferably, the first diamond knot 21 is spliced with the rope body 11, that is, the rope thread forming the first diamond knot 21 and the rope thread forming the rope body 11 are connected by knitting at a position adjacent to the first eyelet 111, in other words, the rope body 11 is split at a position adjacent to the first eyelet 111, the split rope strands are knotted to form the first diamond knot 21, and the first diamond knot 21 is spliced with the rope body 11 so that the first diamond knot 21 and the rope body 11 are integrated, and the connection between the two is more firm and reliable.

In other embodiments, as shown in fig. 1 and 2, the towing rope 100 further includes a first connecting rope 23, where the first connecting rope 23 has a first free end 231 and a first connecting end 232, and the first diamond knot 21 is disposed at the first free end 231, and the first connecting end 232 is connected to the rope 11. In other words, the first diamond knot 21 is connected to the string 11 by the first connecting string 23, and the connection position of the first connecting string 23 and the string 11 is adjacent to the first eye 111.

With the first connection string 23, the first diamond knot 21 can be more conveniently arranged and the first diamond knot 21 can be buckled with and separated from the first eye 111. When the first diamond knot 21 is fastened and tightened with the first eye 111, the position where the first eye 111 is stopped is the connection position of the first connecting rope 23 and the first diamond knot 21. In addition, the connection between the first connection rope 23 and the rope 11 is easier than the connection between the first diamond knot 21 and the rope 11, so that the manufacturing difficulty of the towing rope 100 is reduced.

In some embodiments, as shown in fig. 1 and 2, the first connection end 232 of the first connection rope 23 is spliced with the rope 11, that is, the first connection rope 23 is integrated with the rope 11, so that the connection between the first connection rope 23 and the rope 11 is more firm, and the integrity of the towing rope 100 is stronger and the use is more reliable.

In some embodiments, as shown in fig. 1 and 2, the first diamond knot 21 is integrally formed with the first connecting string 23. For example, the first free end 231 of the first connecting string 23 is knotted to form the first diamond knot 21. The first diamond knot 21 is integrally formed with the first connecting rope body 23, so that the integrity of the towing rope 100 is stronger and the use reliability is higher.

In some embodiments, as shown in fig. 1 and 2, the length of the first connecting rope 23 is less than the length of the rope segment between the first connecting end 232 and the first eyelet 111, preferably the length of the rope segment between the first connecting end 232 and the first eyelet 111 is 1.5-3 times the length of the first connecting rope 23. The length of the rope segment between the first connection end 232 and the first eyelet 111 is 10-50 times the length between the first connection end 232 and the second end of the rope 11.

Of course, the length of the first connecting string 23 may be equal to or greater than the length of the string end between the first connecting end 232 and the first eyelet 111.

In some embodiments, as shown in fig. 1 and 2, the towing rope 100 further includes a first connection fastening sleeve 24 and a first fastening sleeve 25, where the first connection fastening sleeve 24 is sleeved at the connection position of the first connection rope 23 and the rope 11, and is used for fastening and reinforcing the connection strength of the first connection rope 23 and the rope 11, so as to avoid the first connection rope 23 from being separated or disconnected from the rope 11. The first fastening sleeve 25 is sleeved on the root of the first eye 111, and is used for fastening and reinforcing the strength of the root of the first eye 111, so as to avoid the root of the first eye 111 from being torn or separated due to external force.

As an example, as shown in fig. 1 and 2, the first connection fastening sleeve 24 and the first fastening sleeve 25 are each formed by winding a ligature wire. The ligature line of first connection binding sleeve 24 twines in the junction of first connection rope body 23 and rope body 11, and the ligature line of first binding sleeve 25 twines in the root of first eye 111.

In another example, the first connecting fastening sleeve 24 and the first fastening sleeve 25 may be made of other materials, such as rubber sleeves, metal sleeves, and the like.

In some preferred embodiments, as shown in fig. 1, the first connecting rope 23 has the same direction as the first end of the rope 11, in other words, the first connecting rope 23 naturally extends from the first connecting end 232 to the first eye 111, and the first diamond knot 21 is fastened to the first eye 111 to stretch the towing rope 100, and the first connecting rope 23 is tightened.

In some embodiments, as shown in fig. 1 and 6, the tow rope 100 further includes a first stop collar 26, the first stop collar 26 is positioned around the root of the first eyelet 111, and the first stop collar 26 is positioned between the first fastening collar 25 and the root of the first eyelet 11. The first stopper 26 is movable along the length direction of the string body 11 to change the size of the first eye 111. When the first stop collar 26 moves toward the first eye 111, the first eye 111 is contracted, and when the first stop collar 26 moves away from the first eye 111, the first eye 111 can be enlarged. Fig. 6A to 6C show a process in which the first stopper 26 is gradually moved toward the first eye 111 and the first eye 111 is gradually contracted.

After the first annular hole 111 is buckled with the first diamond knot 21, the first limiting sleeve 26 is moved towards the first annular hole 111 to reduce the first annular hole 111, so that the first diamond knot 21 can be better clamped, the first diamond knot 21 is prevented from being separated from the first annular hole 111, and the first annular hole 111 is buckled with the first diamond knot 21 more firmly. After the use of the towing rope 100, the first stop collar 26 is moved away from the first eye 111 to enlarge the first eye 111, so as to facilitate the detachment of the first diamond knot 21 from the first eye 111. As shown in fig. 6A, the first eye 111 has the largest size. As shown in fig. 6C, the first eye 111 is the smallest in size.

The first stop collar 26 effectively avoids the possible deviation and loosening rebound conditions during use, avoids personal safety problems or property compliance caused by the deviation and loosening rebound conditions, and ensures the safety and stability of the towing rope 100 during use.

Optionally, the first stop collar 26 is a rubber collar. Thus, the first stopper 26 can be reliably fitted to the rope 11 by deforming the first stopper 26, and loosening of the first stopper 26 is avoided.

As an example, as shown in fig. 7 to 11, the first spacer 26 has a first through hole 261 and a second through hole 262 side by side, and an isolation portion 263 for isolating the first through hole 261 and the second through hole 262 is provided in the first spacer 26. The end face of the isolation portion 263 far away from the first annular hole 111 is flush with the end face of the first stop collar 26 far away from the first annular hole 111, and the end face of the isolation portion 263 near the first annular hole 111 is lower than the end face of the first stop collar 26 near the first annular hole 111.

The first stop collar 26 is disposed at the root of the first eyelet 111, that is, at the crotch of the first end of the rope 11, and two rope segments of the rope 11 for forming the first eyelet 111 respectively pass through the first through hole 261 and the second through hole 262, and the isolation portion 263 is located between the two rope strands.

As shown in fig. 7-11, the first through hole 261 is a circular hole, and the inner wall surface of the first through hole 261 is provided with a plurality of protrusions for increasing friction force, the second through hole 262 is a flat hole, and the width and length of the second through hole 262 are smaller than the diameter of the first through hole 261, so that the second through hole 262 can clamp a rope body more tightly, the friction force between the first stop collar 26 and the rope body is increased, and the first stop collar 26 is prevented from loosening.

Alternatively, the first through hole 261 of the first stop collar 26 may be a flat hole similar to the second through hole 262, or the second through hole 262 may be a circular hole similar to the first through hole 261. In other examples, the first stop collar 26 may be provided with a through hole that is directly sleeved on the root of the first eye 111.
