Abstract
Description
Technical Field
[0001] This application relates to the technical field of ropes, and in particular to an integrated soft shackle trailer rope. Background Technology
[0002] Shackles are widely used as connecting components in lifting, rock climbing, rescue, and marine engineering. Traditional shackles are mainly made of metal materials (such as carbon steel and alloy steel), which have high strength and durability, but have some limitations, such as being heavy, lacking flexibility, and having material corrosion problems.
[0003] In response, there are already some improved solutions in the field of flexible connections, which form flexible shackles by weaving ropes. For example, Chinese patent application number 202120088212.5 discloses a new type of flexible shackle with long service life and high strength. When using this type of shackle, the diamond knots and ring buckles at both ends are connected, and then it is connected to the rope for use.
[0004] These types of soft shackles are formed by weaving a single rope, so they are separate from the connecting telescopic lock. Although it is relatively convenient to connect them with metal rings or other connecting structures, using metal rings will lead to the problems of traditional shackles. Connecting them with ropes requires a high level of skill in the connection method, and it is difficult for untrained personnel to operate them. Utility Model Content
[0005] To address the aforementioned issues, this application provides an integrated soft shackle trailer rope.
[0006] This application provides an integrated soft shackle trailer rope, which adopts the following technical solution:
[0007] An integrated soft shackle tow rope includes a tow rope and a soft shackle. The soft shackle has a fork for connecting the tow rope. One end of the tow rope is folded in half, wrapped around the fork, and then woven together.
[0008] In one embodiment: the soft shackle includes an integrally formed first shackle rope and second shackle rope, and the fork is formed by the first shackle rope passing through the second shackle rope and then the second shackle rope passing through the first shackle rope.
[0009] In one embodiment: the first shackle cord passes through the second shackle cord to form a loop hook; the section where the first shackle cord and the second shackle cord are parallel after passing through the second shackle cord is an adjustment section; the section of the second shackle cord that passes through the first shackle cord is the main cord section; after the second shackle cord passes out of the first shackle cord, the first shackle cord passes through the second shackle cord to form the fork; the ends of the first shackle cord and the second shackle cord are woven to form a diamond knot; the loop hook, adjustment section, main cord section, fork, and diamond knot are arranged sequentially.
[0010] In one embodiment: the distance between the fork and the ring buckle is at least 1.5 times the distance between the fork and the diamond knot.
[0011] In one embodiment: the trailer rope includes an integrally formed first rope and second rope, and the connection structure between the trailer rope and the soft shackle is such that the first rope passes through the fork, wraps around once, and then passes through the fork again.
[0012] In one embodiment: the first rope and the second rope are interlaced to form a woven structure of a trailer rope.
[0013] In one embodiment: the second rope is shorter than the first rope, and the first rope passes through the end of the second rope.
[0014] In one embodiment, the first rope and the second rope interweave each other at least twice. Attached Figure Description
[0015] Figure 1 This is a structural schematic diagram of this embodiment.
[0016] In the diagram, 100 is the soft shackle; 110 is the first shackle rope; 120 is the second shackle rope; 130 is the loop soft shackle; 140 is the adjusting section; 150 is the main rope section; 160 is the fork; 170 is the diamond knot; 200 is the trailer rope; 210 is the first vehicle rope; and 220 is the second vehicle rope. Detailed Implementation
[0017] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.
[0018] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0019] An integrated soft shackle tow rope, such as Figure 1 As shown, it includes a trailer rope 200 and a shackle 100. The shackle 100 is provided with a fork 160 for connecting the trailer rope 200. One end of the trailer rope 200 is folded in half, wrapped around the fork 160, and then woven together.
[0020] The soft shackle 100 includes an integrally formed first shackle rope 110 and second shackle rope 120, which are formed by bending the same rope.
[0021] At the bend, the first shackle cord 110 passes through the second shackle cord 120 to form a loop snap 130. The section where the first shackle cord 110 and the second shackle cord 120 are parallel is the adjusting section 140. The adjusting section 140 allows the first shackle cord 110 to move on the second shackle cord 120, thereby adjusting the size of the loop snap 130. It should be noted that the loop snap 130 is at its smallest size when the lengths of the first shackle cord 110 and the second shackle cord 120 on the adjusting section 140 are equal.
[0022] The second shackle rope 120 is inserted into the first shackle rope 110 as a main rope segment 150. The main rope segment 150 forms a single rope structure. The second shackle rope 120 is located inside the first shackle rope 110. This structure has better overall integrity and can form better structural strength.
[0023] After the second shackle rope 120 passes through the first shackle rope 110, the first shackle rope passes through the second shackle rope 120 to form a fork 160. It should be noted that the main rope segment 150 is not a necessary structure; in some soft shackles 100, the main rope segment 150 may be omitted. In this case, the fork 160 is formed by the first shackle rope 110 passing through the second shackle rope 120, and then the second shackle rope 120 passing through the first shackle rope 110. Of course, it is acceptable for either the first shackle rope 110 to pass through the second shackle rope 120 first, or vice versa.
[0024] Finally, the ends of the first shackle cord 110 and the second shackle cord 120 are braided to form a diamond knot 170, and the ring soft buckle 130, adjustment section 140, main rope section 150, fork 160 and diamond knot 170 on the soft shackle 100 are set in sequence.
[0025] The distance between the fork 160 and the ring buckle 130 is at least 1.5 times the distance between the fork 160 and the diamond knot 170. This arrangement allows the stress point of the soft shackle 100 to be located in the adjustment section 140 or the main rope section 150 during use, preferably in the main rope section 150.
[0026] In addition, the size of the fork 160 is set as small as possible. This can prevent the tow rope 200 from moving relative to the fork 160, thereby reducing the wear caused by friction between the two and improving the service life.
[0027] The tow rope 200 includes an integrally formed first tow rope 210 and second tow rope 220. In this embodiment, the distinction between the first tow rope 210 and the second tow rope 220 can be seen from the dotted lines in the figure. However, it should be further explained that the first tow rope 210 and the second tow rope 220 are integral; therefore, there is actually no clear dividing line between them. The naming in this application, using the terms "first tow rope 210" and "second tow rope 220," is only for better explanation and illustration.
[0028] The connection structure between the tow rope 200 and the soft shackle 100 is such that the first tow rope 210 passes through the fork 160, wraps around once, and then passes through the fork 160 again. This structure allows the first tow rope 210 to be connected to both the first shackle rope 110 and the second shackle rope 120 simultaneously, resulting in a stronger connection.
[0029] In addition, the first rope 210 and the second rope 220 are interwoven with each other in sequence to form the woven structure of the trailer rope 200, and the first rope 210 and the second rope 220 are interwoven with each other at least twice.
[0030] Furthermore, in order to avoid the ends of the first rope 210 and the second rope 220 being exposed and affecting the aesthetics, in this embodiment, the length of the second rope 220 is set to be less than that of the first rope 210. After the first rope 210 and the second rope 220 are threaded through multiple times, the first rope 210 is finally threaded into the second rope 220 until the first rope 210 emerges from the end of the second rope 220.
[0031] It should be noted that the first shackle cord 110, the second shackle cord 120, the first machine rope 210, and the second machine rope 220 are all woven from multiple strands of ultra-high molecular weight polyethylene (UHMWPE) single ropes, typically using an even number of UHMWPE single ropes of 8, 12, 16, or 18 strands. Therefore, the aforementioned threading refers to connecting a needle to the ends of the first shackle cord 110, the second shackle cord 120, the first machine rope 210, and the second machine rope 220, and then directly threading the multiple strands of UHMWPE single rope through the needle. After threading, it is usually required that the multiple strands of UHMWPE single rope be divided into two equal parts.
[0032] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
