Abstract
Description
Technical Field
[0001] This invention relates to the field of braided rope technology, specifically to an adjustable flexible connecting rope and its usage method. Background Technology
[0002] Braided ropes have a wide range of applications in daily life, industrial production, and outdoor work. Traditional braided ropes typically only have basic functions such as binding and traction, which are clearly insufficient in some special scenarios. In the field of outdoor adventure, activities such as rock climbing, camping, and hiking place even higher demands on the precision of braided rope length. In rock climbing, if the rope is too long, it increases the fall distance and impact force, threatening the user's safety; if it is too short, it cannot cover the entire climbing route. In camping, the fixed-length design of braided ropes used for setting up tents and securing equipment makes it difficult to adapt to different terrains and equipment sizes.
[0003] In existing technologies, the length of a braided rope is usually adjusted by cutting off the excess part after knotting the rope. However, this method is destructive and cannot restore the original length, resulting in a reduced rope reuse rate and material waste.
[0004] Therefore, it is necessary to provide an adjustable flexible connecting rope and a method of using it. Summary of the Invention
[0005] The purpose of this invention is to provide an adjustable flexible connecting rope and its usage method to solve the problem of low rope reuse rate caused by the existing method of adjusting the length of the braided rope by tying knots and cutting off the excess part.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable flexible connecting rope, comprising: The rope has a first knot at both ends and a plurality of buttonholes that are arranged at intervals along the length of the rope to cooperate with the first knots. An adjustment assembly is threaded onto the rope, and the rope is wound inside the adjustment assembly; A limiting component for engaging with the buttonhole, the limiting component being fixedly connected to the first knot.
[0007] Furthermore, the rope is divided into a first strand and a second strand, which together form the buttonhole.
[0008] Furthermore, it also includes: a second knot spaced apart from the first knot, and the rope body has at least one continuous arrangement of the first knot and the second knot.
[0009] Furthermore, the adjustment component includes: A shell is inserted through the rope, and two first through holes are symmetrically opened at both ends of the shell for the rope to pass through or out. A first rotating shaft is disposed inside the housing. A second through hole is provided on the side of the housing near the first rotating shaft. One end of the first rotating shaft is rotatably connected to the inner wall of the housing via a bearing, and the other end passes through the second through hole and is hinged to an operating handle. The first rotating shaft is rotatably connected to the second through hole via a bearing. A limit rod is hinged to the end of the operating handle away from the first rotating shaft. A groove is provided on the outer wall of the housing to adapt to the limit rod. The drive gear is fixedly connected to the first rotating shaft; A second rotating shaft is spaced apart from the first rotating shaft, and both ends of the second rotating shaft are rotatably connected to both ends of the housing via bearings; a drum is fixedly sleeved on the second rotating shaft, and the rope portion is wound around the drum; The driven gear is fixedly connected to the second rotating shaft, and the driven gear meshes with the driving gear; the driven gear is spaced apart from the drum.
[0010] Furthermore, the limiting component includes: The first connecting block, the connecting rod, and the second connecting block are connected in sequence. The second connecting block has an arc-shaped connector fixedly connected to the side away from the connecting rod, and the connector is fixedly connected to the first knot. Multiple fins are spaced apart and arranged in an array around the connecting rod. One end of each fin is connected to the first connecting block, and the other end is a free end. A sleeve is slidably fitted onto the outside of the first connecting block. One end of the sleeve has an opening, and a limiting block is fixedly connected to the opening for abutting against the side of the second connecting block near the fin. The inner wall of the limiting block is pressed and connected to the fin.
[0011] Furthermore, the rope is integrally woven from ultra-high molecular weight polyethylene fiber, polyester, polyamide, polypropylene, aramid, or any one or more of the above fiber materials.
[0012] Furthermore, the rope is woven using a plain weave method.
[0013] Furthermore, the rope body is fitted with multiple anti-wear sleeves at intervals.
[0014] Furthermore, the rope also includes multiple segments of luminescent fibers, which are arranged in a ring array.
[0015] A method of using the adjustable flexible connecting rope as described above includes the following steps: S1, Inspect the rope, including the first knot, the second knot, and the buttonhole; S2, Loop the rope over the human body or object, so that the first knot and the second knot pass through the same buttonhole in sequence; tighten the rope, and the second knot is locked in place with the buttonhole.
[0016] Furthermore, after the first knot and the second knot pass through the same buttonhole in turn, the first knot passes through another buttonhole.
[0017] Furthermore, in step S2, the first knot and the second knot are passed through different buttonholes respectively, the rope is tightened, and the first knot and the second knot are secured with different buttonholes respectively.
[0018] Furthermore, in step S1, the adjustment component is installed at the corresponding position on the safety rope, and the first knot is connected to the limiting component.
[0019] The present invention has the following beneficial effects: 1. This invention can adjust the effective length by changing the connection position of the first knot and the second knot with the buttonhole. The buttonhole and the knot form an "interlock". Changing the position can improve the connection firmness and prevent the knot from slipping.
[0020] 2. This invention extends the usable length of the rope by removing the limiting rod from the groove, thus freeing it from restricting the rotation of the operating handle. Then, by simultaneously pulling the ropes at both ends of the housing, the rope wound on the drum is pulled out of the housing. By manually rotating the operating handle, the first shaft drives the drive gear, which in turn drives the second shaft. The second shaft then drives the drum, causing the rope to wind around it, thereby shortening the usable length of the rope. This solves the problem of low rope reuse rates caused by the existing method of adjusting the length of braided rope by knotting and cutting off excess portions.
[0021] 3. In this invention, the limiting block is slid to the second connecting block by sliding the sleeve, thereby retracting all the fins into the sleeve. Then, the sleeve drives the first knot through the eyelet. Then, the sleeve is slid in the opposite direction to slide the limiting block to the first connecting block. At this time, since the fins are no longer under the squeezing force of the limiting block, all the fins spread out in all directions. When the rope is tightened, the eyelet is engaged between the fins and the connecting rod, effectively preventing the rope from breaking. Attached Figure Description

[0024] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example
[0025] Reference Figure 1In this embodiment, an adjustable flexible connecting rope includes: a rope body 1, with a first knot 2 at both ends of the rope body 1, and a plurality of buttonholes 3 spaced along the length of the rope body 1 to cooperate with the first knots 2; an adjustment component 6 threaded onto the rope body 1, with the rope body 1 wound inside the adjustment component 6; and a limiting component 5 for engaging with the buttonholes 3, the limiting component 5 being fixedly connected to the first knots 2.
[0026] Rope 1 is made of ultra-high molecular weight polyethylene fiber, polyester, polyamide, polypropylene, aramid, or any one or more of these fiber materials in a one-piece braided structure. These fiber materials have good elongation (breaking elongation of approximately 20-30%), which allows them to absorb impact energy through moderate stretching during a fall, reducing the impact on the climber and anchor points, thus providing cushioning protection. During rock climbing, the rope frequently rubs against rocks and carabiners; its abrasion resistance is superior to natural fibers such as cotton and linen, and it has strong fatigue resistance, capable of withstanding multiple stretch-recovery cycles. Its low water absorption (approximately 4-8%) means that even in humid environments, its strength decreases only slightly (usually ≤10%), and it is not easily rotten due to moisture, making it suitable for complex outdoor environments. The breaking strength of the fiber material can reach 4-9 grams per denier (a unit of fiber strength), capable of withstanding the enormous impact force of a climber's fall (international standards require a maximum single-rope impact force ≤12kN, approximately equivalent to the impact force of 1.2 tons). Rope 1 is woven with twelve strands, which has excellent load-bearing capacity and strong tear resistance (after a single strand breaks, the other strands can still share the tension); the surface is smooth and dense, and its wear resistance and cut resistance are outstanding.
[0027] The rope body 1 also includes multiple segments of luminous fibers arranged in a ring array. The surface of the luminous fibers is waterproofed and stores light energy during the day or when illuminated by lamps. When used at night, the luminous fibers enable the rope body 1 to emit fluorescence, making the rope body 1 more visible and improving safety to a certain extent.
[0028] Specifically, refer to Figure 4 The rope 1 is divided into a first strand 301 and a second strand 302, which together form a buttonhole 3. Both the first strand 301 and the second strand are made of various fiber materials wound and polymerized through a rotational twisting process, forming a stronger rope structure. This operation improves the overall integrity, strength, and durability of the rope by changing the arrangement of the fiber materials.
[0029] More specifically, the rope body 1 is fitted with multiple polyurethane (PU) coated abrasion sleeves at intervals. The polyurethane (PU) surface is smooth and has moderate hardness, which reduces the coefficient of friction with the rock while forming a hard protective layer to resist the penetration of sharp objects. The polyurethane (PU) material has good water resistance, preventing water from seeping into the rope body (although most climbing ropes are waterproof, long-term dampness may still affect their strength). In addition, its thinness and strong fit, usually using a thin coating design, hardly affect the feel and operation of the rope body, making it suitable for free climbing, competitive climbing, or scenarios where lightweight requirements are extremely high, or where it is frequently used on wet rock faces (such as waterfall climbing areas).
[0030] In this embodiment, an adjustable flexible connecting rope further includes a second knot 4 spaced apart from the first knot 2, and the rope body 1 has at least one continuously arranged first knot 2 and second knot 4. In use, by continuously passing the first knot 2 and the second knot 4 through the buttonhole 3, the double knots prevent the rope body 1 from loosening, thus improving safety.
[0031] The first method of using the adjustable flexible connecting rope in this embodiment includes the following steps: S1, Inspect the rope, including the first knot, the second knot, and the buttonhole; S2, Loop the rope over the human body or object, so that the first knot and the second knot pass through the same buttonhole in sequence; tighten the rope, and the second knot is locked in place with the buttonhole.
[0032] The second method of using the adjustable flexible connecting rope in this embodiment includes the following steps: S1, Inspect the rope, including the first knot, the second knot, and the buttonhole; S2, Loop the rope around the human body or object, so that the first knot and the second knot pass through the same buttonhole in turn, and then the first knot passes through another buttonhole; tighten the rope, the second knot is locked with the buttonhole, and the first knot is locked with another buttonhole.
[0033] The third method of using the adjustable flexible connecting rope in this embodiment includes the following steps: S1, Inspect the rope, including the first knot, the second knot, and the buttonhole; S2, loop the rope around the human body or object, so that the first knot and the second knot pass through different buttonholes respectively, tighten the rope, and the first knot and the second knot are locked in place with the buttonholes respectively.
[0034] In this embodiment, by changing the connection position of the first knot and the second knot with the buttonhole, the effective length can be adjusted, and the buttonhole and the knot form an "interlock". Changing the position can improve the connection firmness and prevent the knot from slipping. Example
[0035] Reference Figure 5-6In this embodiment, the adjustment component 6 includes a housing 601 that is threaded onto the rope 1, and two first through holes are symmetrically opened at both ends of the housing 601 for the rope 1 to pass through or out.
[0036] A first rotating shaft 603 is disposed inside the housing 601. A second through hole is provided on the side of the housing 601 near the first rotating shaft 603. One end of the first rotating shaft 603 is rotatably connected to the inner wall of the housing 601 through a bearing, and the other end passes through the second through hole and is hinged to an operating handle 604. The first rotating shaft 603 is rotatably connected to the second through hole through a bearing. A limit rod 605 is hinged to the end of the operating handle 604 away from the first rotating shaft 603. A groove 6011 is provided on the outer wall of the housing 601 to be adapted to the limit rod 605.
[0037] The driving gear 602 is fixedly connected to the first rotating shaft 603. A second rotating shaft 607 is spaced apart from the first rotating shaft 603, with both ends of the second rotating shaft 607 rotatably connected to both ends of the housing 601 via bearings. A drum 608 is fixedly sleeved on the second rotating shaft 607, and part of the rope 1 is wound around the drum 608. The driven gear 606 is fixedly connected to the second rotating shaft 607 and meshes with the driving gear 602; the driven gear 606 and the drum 608 are spaced apart.
[0038] In this embodiment, by removing the limiting rod 605 from the groove 6011, it no longer restricts the rotation of the operating handle 604. Then, by simultaneously pulling the ropes 1 at both ends of the housing 601, the ropes 1 wound on the drum 608 are pulled out of the housing 601, thereby extending the usable length of the ropes 1. By manually rotating the operating handle 604, the first rotating shaft 603 drives the driving gear 602 to rotate, while the driven gear 606 drives the second rotating shaft 607 to rotate. The second rotating shaft 607 drives the drum 608 to rotate, and the rotation of the drum 608 winds the ropes 1 onto the drum 608, thereby shortening the usable length of the ropes 1. This solves the problem of low rope reuse rate caused by the existing method of adjusting the length of the braided rope by knotting the rope and cutting off the excess part.
[0039] It needs to be explained in detail that, referring to Figure 7-10 In this embodiment, the limiting component 5 includes: a first connecting block 502, a connecting rod 507, and a second connecting block 505 connected in sequence; an arc-shaped connector 506 is fixedly connected to the side of the second connecting block 505 away from the connecting rod 507, and the connector 506 is fixedly connected to the first knot 2.
[0040] Multiple spaced fins 503 are arranged in an array around a connecting rod 507. One end of each fin 503 is connected to a first connecting block 502, and the other end is free. A sleeve 501 is slidably fitted over the first connecting block 502. One end of the sleeve 501 has an opening, at which a limiting block 504 is fixedly connected for abutting against the side of a second connecting block 505 near the fin 503. The inner wall of the limiting block 504 is pressed against the fin 503. The fins 503 are made of corrosion-resistant, moderately hard stainless steel, suitable for outdoor and humid environments (such as backpack eyelets and climbing equipment eyelets). They are not easily deformed during snap-fitting and have a long service life.
[0041] In this embodiment, by sliding the sleeve 501, the limiting block 504 is slid to the second connecting block 505, thereby retracting all the fins 503 into the sleeve 501. Then, the sleeve 501 drives the first knot 2 through the buttonhole 3. Then, the sleeve 501 is slid in the opposite direction, and the limiting block 504 is slid to the first connecting block 502. At this time, since the fins 503 are no longer under the squeezing force of the limiting block 504, all the fins spread out in all directions. When the rope 1 is tightened, the buttonhole 3 is engaged between the fins 503 and the connecting rod 507, effectively preventing the rope 1 from breaking.
[0042] The method of using the adjustable flexible connecting rope in this embodiment includes the following steps: S1, inspect the rope 1, including the first knot 2, the second knot 4 and the eyelet 3, install the adjusting component 6 in the corresponding position of the safety rope, and connect the first knot 2 to the connector 506. S2, by removing the limiting rod 605 from the groove 6011, it no longer restricts the rotation of the operating handle 604. Then, by simultaneously pulling the ropes 1 at both ends of the housing 601, the ropes 1 wound on the drum 608 are pulled out of the housing 601, thereby extending the usable length of the ropes 1. By manually rotating the operating handle 604, the first rotating shaft 603 drives the driving gear 602 to rotate, while the driven gear 606 drives the second rotating shaft 607 to rotate. The second rotating shaft 607 drives the drum 608 to rotate, and the rotation of the drum 608 winds the ropes 1 onto the drum 608, thereby shortening the usable length of the ropes 1. S3, the rope 1 is placed on the human body or object. By sliding the sleeve 501, the limiting block 504 is slid to the second connecting block 505, thereby retracting all the fins 503 into the sleeve 501. Then, the sleeve 501 drives the first knot 2 through the buttonhole 3. Then, the sleeve 501 is slid in the opposite direction, and the limiting block 504 is slid to the first connecting block 502. At this time, since the fins 503 are no longer under the squeezing force of the limiting block 504, all the fins 503 spread out in all directions. When the rope 1 is tightened, the buttonhole 3 is engaged between the fins 503 and the connecting rod 507, effectively preventing the rope 1 from breaking. Example
[0043] See attached document Figure 11 The first knot 2 and the second knot 4 are preferably figure-eight anti-slip knots. A figure-eight anti-slip knot is a common anti-slip knot, usually tied at the end of the rope to prevent it from slipping out of holes, pulleys, etc. Its structure is relatively simple, and its anti-slip effect is good. Figure 11 As you can see, the knot has a shape similar to the number "8". This type of knot is often used in scenarios such as rock climbing and sailing when anti-slip treatment is needed at the end of the rope.
