Description

Technical Field

[0001] This utility model relates to the technical field of rope connection components, specifically a detachable three-way rope connector. Background Technology

[0002] As is well known, in outdoor operations (such as mountaineering and high-altitude maintenance), logistics bundling, sports rope connection, and emergency rescue scenarios, it is often necessary to connect multiple ropes in a three-way intersection to achieve force transmission, load distribution, or rope redirection. Therefore, the reliability, ease of assembly and disassembly, and rope protection provided by the three-way rope connector, as a core connecting component, directly affect the overall safety and efficiency of the operation.

[0003] The existing three-way rope connectors have the following main drawbacks:

[0004] Some connectors use a one-piece molded structure, which is simple in structure but takes up a lot of space during transportation, and the whole unit needs to be replaced if a single part is damaged, resulting in high maintenance costs; other detachable connectors rely on complex clips or special fasteners, which require special tools for disassembly and assembly, making them inconvenient to operate and difficult to meet the needs of rapid outdoor operations.

[0005] Most connectors are fixed by a single thread or snap-fit, which can easily loosen or slip under vibration, impact or long-term stress, posing a safety hazard, especially under heavy load conditions. Some products have unreasonable positioning structure design, which causes the bolts to move axially, further reducing the stability of the connection.

[0006] Traditional connectors often have fixed-angle lifting rings, which can easily lead to sharp bends and localized stress concentrations after the ropes are connected, resulting in a significant decrease in rope strength. Some lifting rings also have point or angular contact points with the ropes, which can cause rope wear and shorten its lifespan with long-term use.

[0007] In view of the shortcomings of the existing technology, there is an urgent need for a detachable three-way rope connector that is structurally reasonable, easy to assemble and disassemble, reliable in connection, and can reduce the loss of rope strength, so as to meet the safety requirements of various scenarios.

[0008] (a) Technical problems to be solved

[0009] To address the shortcomings of existing technologies, this utility model provides a detachable three-way rope connector.

[0010] (II) Technical Solution

[0011] To achieve the above objectives, this utility model provides the following technical solution: a detachable three-way rope connector, comprising a triangular block and a lifting ring, wherein an assembly mechanism is provided between the lifting ring and the triangular block, the assembly mechanism comprising a positioning hole, a locking hole, and an assembly hole, the assembly hole being formed on the triangular block, the positioning hole being formed at both ends of the lifting ring, the locking hole being formed on one side of the lifting ring and communicating with one of the positioning holes on the lifting ring, the other positioning hole having a polygonal groove, a bolt being provided in the assembly hole, the bolt passing through the two positioning holes, a nut being provided between one end of the bolt and the polygonal groove, a limiting ring being provided on the bolt, the limiting ring having an annular groove, a locking bolt being provided in the locking hole, the locking bolt abutting against the annular groove, and three lifting rings being provided and arranged in a circular array around the triangular block as the axis.

[0012] Furthermore, the triangular block has an equilateral triangle structure, and the three assembly holes are respectively opened at the three vertices of the triangular block.

[0013] Furthermore, the polygonal groove is a regular hexagonal groove, the nut is a hexagonal nut adapted to the regular hexagonal groove, and the nut and the regular hexagonal groove are interference fit.

[0014] Furthermore, the lifting ring has a U-shaped structure.

[0015] Furthermore, the triangular block and the lifting ring are both made of high-strength aluminum alloy, and the bolts, nuts and locking bolts are made of stainless steel.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a detachable three-way rope connector, which has the following advantages:

[0018] This detachable three-way rope connector uses an assembly mechanism consisting of bolts, nuts, and locking bolts to achieve a detachable connection between the lifting ring and the triangular block. Assembly is simple: align the positioning holes and assembly holes, insert the bolt, tighten the nut, and lock the locking bolt. Disassembly is the reverse process. No special tools are required, and the operation is simple, facilitating rapid outdoor work and allowing for individual replacement of damaged lifting rings or fasteners, reducing maintenance costs. Its compact size after disassembly facilitates transportation and storage. The nut engages with a polygonal groove for circumferential fixation, preventing loosening; the locking bolt abuts against the annular groove on the bolt's limiting ring, restricting axial movement and effectively preventing connection failure under vibration and impact conditions. This double-locking structure significantly improves the connector's resistance to loosening, ensuring connection stability under heavy loads or long-term use and reducing safety risks.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4This utility model is a detachable three-way rope connector, including a triangular block 1 and a lifting ring 2. An assembly mechanism is provided between the lifting ring 2 and the triangular block 1. The assembly mechanism includes a positioning hole 3, a locking hole 4, and an assembly hole 5. The assembly hole 5 is opened on the triangular block 1. The positioning holes 3 are opened at both ends of the lifting ring 2. The locking hole 4 is opened on one side of the lifting ring 2 and connects to one of the positioning holes 3 on the lifting ring 2. A polygonal groove is opened on the other positioning hole 3. A bolt 6 is provided in the assembly hole 5. The bolt 6 passes through the two positioning holes 3. A nut 7 is provided between one end of the bolt 6 and the polygonal groove. A limiting ring 8 is provided on the bolt 6. An annular groove 9 is opened on the limiting ring 8. A locking bolt 10 is provided in the locking hole 4. The locking bolt 10 abuts against the annular groove 9. There are three lifting rings 2 arranged in a circular array with the triangular block 1 as the axis. In this embodiment, the positioning holes 3 at both ends of the lifting ring 2 and the assembly holes 5 on the triangular block 1 are aligned so that the axes of the three coincide. Insert the bolt 6 through the positioning hole 3 on one side of the lifting ring 2, then through the assembly hole 5 and the positioning hole 3 on the other side, until the end of the bolt 6 extends into the polygonal groove. Install the nut 7 in the polygonal groove and tighten the nut 7 to initially fix the lifting ring 2 and the triangular block 1 together. Insert the locking bolt 10 into the locking hole 4 and tighten the locking bolt 10 so that its side abuts against the annular groove 9 on the limiting ring 8 of the bolt 6, completing the axial positioning of the bolt 6. Repeat the above steps to fix the three lifting rings 2 to the triangular block 1 respectively through the assembly mechanism, forming a three-way connection structure. Tighten the locking bolt 10 in the opposite direction so that its end disengages from the annular groove 9 of the bolt 6, releasing the axial limitation on the bolt 6. Loosen and remove the nut 7 in the polygonal groove. Pull the bolt 6 out of the positioning hole 3 and the assembly hole 5 to separate the lifting ring 2 from the triangular block 1. Disassemble the remaining lifting rings 2 as needed to complete the overall disassembly. The three lifting rings 2 can easily fix the rope in three directions, making it convenient to assemble or disassemble the rope and the corresponding lifting ring 2, and providing a reliable connection and fixing method. It is more convenient to form short-distance connections with other ropes, and the connection design of all three ends can be rotated 180 degrees, which effectively avoids the loss of rope strength during use.

[0026] In this design, the triangular block 1 is an equilateral triangle structure, and the three mounting holes 5 are respectively located at the three vertices of the triangular block 1. The equilateral triangle structure has natural symmetry, with the distances from the three vertices to the center being equal, and the included angle between adjacent vertices being 120°. The mounting holes 5 are located at the vertices, ensuring that the circular array of the three lifting rings 2 is completely uniform. This ensures that the ropes in the three directions experience consistent force and balanced force direction, avoiding localized stress concentration; it also improves the overall structural stability of the connector and reduces deformation or damage caused by uneven force during use.

[0027] In this design, the polygonal groove is a regular hexagonal groove, and the nut 7 is a hexagonal nut 7 adapted to the regular hexagonal groove. The nut 7 and the regular hexagonal groove are interference-fitted, with the distance between opposite sides of the regular hexagon precisely matching the opposite side dimensions of the hexagonal nut 7. This interference fit eliminates any gap between the nut 7 and the groove. The polygonal structure restricts the circumferential rotation of the nut 7, providing a reaction force for tightening the bolt 6. This prevents the nut 7 from loosening due to vibration during use, improving connection reliability. No additional fixing of the nut 7 is required during assembly, simplifying the operation. The interference fit enhances the overall structural integrity, preventing connection failure caused by nut 7 displacement.

[0028] In this design, the lifting ring 2 has a U-shaped structure with an arc-shaped transition and no sharp edges, resulting in surface contact rather than point contact when in contact with the rope. The arc-shaped structure can adapt to the bending shape of the rope and possesses a certain degree of elastic deformation capability. This reduces localized pressure at the contact point between the rope and the lifting ring 2, reduces rope wear, and extends the rope's service life. The arc-shaped inner wall facilitates rope winding and threading, improving loading and unloading convenience. It also adapts to ropes of different diameters, enhancing versatility.

[0029] In this design, the triangular block 1 and the lifting ring 2 are both made of high-strength aluminum alloy, while the bolt 6, nut 7, and locking bolt 10 are made of stainless steel. High-strength aluminum alloy combines high strength with lightweight characteristics, with a density only about 1 / 3 that of steel, and also possesses a certain degree of corrosion resistance. Stainless steel (such as 304 and 316 types) has high hardness, wear resistance, and strong rust resistance, making it suitable for components subjected to shear and friction forces. This significantly reduces the overall weight of the connector, making it easy to carry and use outdoors; the triangular block 1 and the lifting ring 2 are not easily deformed, and vulnerable parts such as the bolt 6 and nut 7 are wear-resistant and rust-resistant; it is suitable for complex environments such as outdoors and in humid conditions, extending the overall service life of the connector.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
