Description

Technical Field

[0001] This utility model relates to the technical field of rope connection components, specifically a double-headed rope connector with detachable and rotatable functions. Background Technology

[0002] As is well known, in various rope connection scenarios, rope connectors, as core connecting components, directly impact operational efficiency, safety, and scenario adaptability. However, existing rope connectors still suffer from several technical shortcomings in practical applications that urgently need to be addressed:

[0003] Traditional rope connectors are mostly fixed connection structures, capable of only straight or single-angle connections, and cannot adjust the connection angle according to actual usage requirements. In outdoor operations (such as mountaineering, rock climbing, and high-altitude rescue), ropes often need to adapt to complex spatial layouts, and the force in different directions requires the connector to have angle adjustment capabilities. Existing fixed structures will cause the rope to bend forcibly, which not only limits operational flexibility but also easily causes localized stress concentration on the rope, accelerating rope wear and even breakage. In industrial production (such as hoisting and traction operations), the rope angle changes dynamically during workpiece movement. Fixed connectors are difficult to adapt to such dynamic scenarios, easily causing rope entanglement and pulling, affecting the smoothness of operations.

[0004] Most existing rope connectors use an integrated or multi-bolt fastening structure, requiring specialized tools such as wrenches and screwdrivers for assembly and disassembly, and the process is cumbersome. For example, in outdoor emergency scenarios, operators often cannot carry a full set of tools, making it difficult to quickly assemble or disassemble the connector in an emergency, potentially delaying rescue efforts. In industrial batch operations, frequent connector assembly and disassembly consume a lot of time and manpower, reducing production efficiency. In routine maintenance, the complex assembly and disassembly process also increases the difficulty of operation for users, which is not conducive to the long-term use of the equipment.

[0005] Meanwhile, existing connectors have relatively simple functional designs, making it difficult to balance flexibility, convenience, and safety, and thus failing to meet the diverse usage needs in different scenarios, limiting their application scope. Therefore, there is an urgent need for a rope connector with optimized structure and comprehensive performance to address the many shortcomings of existing technologies. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a double-headed rope connector with detachable and rotatable functions.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution: a double-headed rope connector with detachable and rotatable functions, including an installation head and a fixing head. The top of the installation head is provided with a positioning post, and the top of the positioning post is provided with a limiting plate. The bottom of the fixing head is provided with a T-shaped groove, and an arc groove is provided on the T-shaped groove. The positioning post and the limiting plate abut against the T-shaped groove and contact the arc groove. A T-shaped baffle is provided on the T-shaped groove, and a positioning hole is provided on the T-shaped baffle. Fastening holes are provided between the two sides of the T-shaped groove and the fixing head. A fixing pin is provided in the positioning hole and passes through the two fastening holes. An adjustment hole is provided on both the installation head and the fixing head, and an adjustment pin is provided in the adjustment hole. A U-shaped ring is provided on the adjustment pin, and through holes are provided at both ends of the U-shaped ring. An anti-loosening mechanism is provided on the adjustment pin, and a nut is provided at one end of the adjustment pin. The nut is threadedly connected to the adjustment pin.

[0010] Furthermore, the anti-loosening mechanism includes an annular groove and a fixing hole. The annular groove is formed on the adjusting pin, and the fixing hole is formed on the U-shaped ring. The fixing hole is connected to a through hole of the U-shaped ring, and a threaded post is provided in the fixing hole, which abuts against the annular groove.

[0011] Furthermore, the U-shaped ring is made of alloy steel.

[0012] Furthermore, the nut is a lock-lock nut.

[0013] Furthermore, the positioning post and the limiting plate are integrally formed.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a double-ended rope connector with detachable and rotatable functions, which has the following advantages:

[0016] This detachable and rotatable double-headed rope connector features a precise fit between the positioning post and limiting plate at the top of the mounting head and the T-slot and arc groove on the fixing head. The close fit design of the limiting plate and arc groove ensures stability during rotation and reduces frictional wear between components. The mounting head can rotate 360 ​​degrees around the fixing head, allowing for real-time adjustment according to rope connection angle requirements. This adapts to dynamic angle changes in various scenarios such as outdoor operations, industrial traction, and daily use. It also prevents localized stress concentration caused by forced bending of the rope, effectively reducing rope wear and extending rope life. For example, in mountaineering, operators can quickly adjust the direction of rope force by rotating the mounting head, avoiding hard friction between the rope and rocks or equipment. In hoisting operations, the rotation function adapts to angular shifts during workpiece movement, ensuring uniform rope force and improving operational safety and smoothness.

[0022] 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.

[0023] Please see Figures 1 to 4This utility model is a double-headed rope connector with detachable and rotatable functions, including an mounting head 1 and a fixing head 2. The mounting head 1 has a positioning post 3 at its top, and a limiting plate 4 at its top. The fixing head 2 has a T-shaped groove 5 at its bottom, and an arc groove on the T-shaped groove 5. The positioning post 3 and the limiting plate 4 both abut against the T-shaped groove 5 and contact the arc groove. The T-shaped groove 5 has a T-shaped baffle 6 with a positioning hole. Fastening holes are formed between the two sides of the T-shaped groove 5 and the fixing head 2. A fixing pin 7 is provided in the positioning hole, and the fixing pin 7 passes through the two fastening holes. The mounting head 1 and the fixing head 2... Each head is provided with an adjustment hole 8, and an adjustment pin 9 is provided in the adjustment hole 8. The adjustment pin 9 is provided with a U-shaped ring 10. The two ends of the U-shaped ring 10 are provided with through holes. The adjustment pin 9 is provided with an anti-loosening mechanism. One end of the adjustment pin 9 is provided with a nut 11. The nut 11 is connected to the adjustment pin 9 by a thread. In this embodiment, the positioning pin 3 and the top limiting plate 4 of the mounting head 1 are aligned with the T-shaped groove 5 of the fixing head 2 and inserted, so that the limiting plate 4 fits with the arc groove in the T-shaped groove 5. The T-shaped baffle 6 is placed on the T-shaped groove 5, so that the positioning hole of the T-shaped baffle 6 is aligned with the fastening holes on both sides of the fixing head 2. The fixing pin 7 is inserted through the positioning hole and the two fastening holes to complete the detachable connection between the mounting head 1 and the fixing head 2. Align the through hole of the U-ring 10 with the adjusting hole 8, then pass the adjusting pin 9 through the through hole and the adjusting hole 8, and then thread the nut 11 onto the adjusting pin 9, so that the U-ring 10 is assembled on the mounting head 1 and the fixing head 2. Pass the two ropes to be connected through the U-ring 10 on the mounting head 1 and the fixing head 2 respectively. During use, the mounting head 1 can rotate around the fixing head 2 through the contact between the limiting plate 4 and the arc groove, so as to meet the connection requirements of the ropes at different angles. If disassembly or adjustment is required, unscrew the nut 11, take out the adjusting pin 9, pull out the fixing pin 7, and remove the T-shaped baffle 6 to separate the mounting head 1 and the fixing head 2 and complete the disassembly.

[0024] In this design, the anti-loosening mechanism includes an annular groove 12 and a fixing hole. The annular groove 12 is formed on the adjusting pin 9, and the fixing hole is formed on the U-shaped ring 10. The fixing hole connects to a through hole in the U-shaped ring 10. A threaded post 13 is provided in the fixing hole, and the threaded post 13 abuts against the annular groove 12. By forming an annular groove 12 on the adjusting pin 9 and a fixing hole connecting to the through hole on the U-shaped ring 10, the threaded post 13 is screwed into the fixing hole, and its end abuts against the inner wall of the annular groove 12, forming a radial clamping force. This structure restricts the axial movement and circumferential rotation of the adjusting pin 9 through mechanical contact, forming a double anti-loosening mechanism with the axial locking of the nut 11. This enhances the connection stability between the adjusting pin 9, the U-shaped ring 10, and the adjusting hole 8, preventing the adjusting pin 9 from loosening due to vibration, impact, or other working conditions, and reducing the risk of rope slippage.

[0025] In this design, the U-shaped ring 10 is made of alloy steel. Alloy steel possesses high strength, high hardness, and excellent fatigue resistance and wear resistance. Compared to ordinary steel, its mechanical properties are better suited to the tensile and shear force bearing requirements of rope connections. This enhances the load-bearing capacity and deformation resistance of the U-shaped ring 10, preventing breakage, bending, and other damage under long-term stress or heavy loads, extending the overall service life of the connector, and making it suitable for complex working conditions such as outdoor and industrial applications.

[0026] In this solution, the nut 11 is a lock-lock nut 11. The lock-lock nut 11, through its structural design such as nylon inserts, locking grooves, and metal elastic sheets, increases the friction at the threaded connection between the nut 11 and the adjusting pin 9, or forms a mechanical engagement, thus preventing the relative rotation tendency of the threaded pair. This solves the problem of ordinary nuts 11 easily loosening under vibration environments, achieving stable locking without additional lock-locking parts, simplifying the installation process, reducing maintenance frequency, and ensuring the long-term reliability of the rope connection.

[0027] In this design, the positioning post 3 and the limiting plate 4 are integrally formed. This integral forming process eliminates the seams and weak points in the connection between the positioning post 3 and the limiting plate 4, creating a complete load-bearing structure. It also ensures the coaxiality and dimensional accuracy of the positioning post 3 and the limiting plate 4. This enhances the connection strength between the positioning post 3 and the limiting plate 4, preventing breakage or detachment under stress and extending the service life of the core components. Precise dimensional accuracy ensures a good fit with the T-slot 5 and the arc groove, making the rotation of the mounting head 1 smoother and reducing jamming.

[0028] 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.
