Technical Field
[0001] This utility model relates to the field of wire rope, and in particular to a wire rope that is easy to connect. Background Technology
[0002] Steel wire rope is a metal product composed of multiple strands of helical steel wires woven according to specific rules to form a helical wire bundle structure. This structure mainly consists of steel wires, a core, and lubricating grease. The steel wires are made of carbon steel and alloy steel, produced through cold drawing or cold rolling processes, and their cross-sections are circular or irregular (such as T-shaped, S-shaped, and Z-shaped). Irregularly shaped cross-section steel wires are mainly used to produce sealed steel wire ropes, favored for their high tensile strength and toughness. The core is divided into two main categories: steel core and fiber core. Fiber cores are further subdivided into natural fiber cores and synthetic fiber cores. Natural fiber cores include sisal, jute, and cotton yarn, while synthetic fiber cores are composed of polyethylene and polypropylene filaments. Natural fiber cores can store more lubricating grease, which lubricates the steel wire rope and extends its service life. During the steel wire rope twisting process, the application of lubricating grease is primarily for lubrication, reducing wear on the steel wire surface. Simultaneously, the lubricating grease isolates the steel wire surface from oxygen in the air, effectively inhibiting oxidation and corrosion.
[0003] When subjected to lifting loads, a wire rope that does not rotate or barely rotates around its longitudinal axis is defined as a non-rotating wire rope. This characteristic stems from the opposite lay directions of the inner and outer strands. When a non-rotating wire rope is under load, the torque generated by the core cancels out the torque generated by the outer strands, achieving torque balance. Non-rotating wire ropes are easy to handle due to their excellent fatigue resistance and flexibility. When subjected to tensile loads, the wire rope undergoes different stages of elongation.
[0004] In practical applications of wire ropes, although joints and fasteners are used for secure connections, the robustness of these joints is crucial, especially since wire ropes are commonly used for lifting, tying, traction, and securing operations. Insufficient tightening of fasteners can cause the joints to loosen under stress, reducing work efficiency and potentially leading to accidents. For example, when lifting objects, if the splice of the wire rope is pulled apart due to insufficient tightening, the object may fall, potentially causing serious accidents with property damage and loss of life.
[0005] Insufficient tightening force may be caused by quality problems with the fasteners themselves, improper installation, or wear and loosening due to prolonged use. Furthermore, the stress on the wire rope varies under different environmental and operational conditions, further increasing the challenge of ensuring a secure joint connection. Utility Model Content
[0006] The main objective of this invention is to provide a steel wire rope with convenient joints, which can effectively solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A convenient wire rope includes a wire rope body, a rope sleeve, and a free end. One end of the wire rope body is a free end, which is bent to form a rope sleeve, which is a wire rope hook end.
[0009] The wire rope body and the folded part of the free end are fitted with a fastening sleeve, and the side wall of the fastening sleeve is provided with a through groove. The upper and lower ends of the fastening sleeve are provided with multiple protruding threaded tubes. A rotating handle is inserted into each of the protruding threaded tubes. The rotating handle is provided with a threaded part that matches the protruding threaded tube. The inner end of the rotating handle is a T-key.
[0010] The groove has arc-shaped fastening plates at the top and bottom, which are adapted to the number of rotating handles. The lower end of the arc-shaped fastening plate has a T-shaped hole adapted to the T-key. The T-key and the T-shaped hole realize the limiting connection between the arc-shaped fastening plate and the rotating handle. Different rotating handles drive the arc-shaped fastening plate connected to it to press against the steel wire rope and the fold at the free end. Different pressing forces realize the fixation of the fold.
[0011] In a further optional embodiment, the end face of the rope loop is provided with a perforation, and the inner wall of the rope loop is connected with an anti-slip ring. The inner wall of the anti-slip ring is provided with anti-slip texture, and the anti-slip ring is adapted to the shape of the rope loop. The anti-slip ring is a soft rubber sleeve and is connected to the wire rope body by an adhesive.
[0012] In a further alternative, the wire rope body, the rope sleeve, and the free end are designed as a single unit, the cross-section of the fastening sleeve is an elliptical ring, the inner wall of the fastening sleeve is provided with anti-slip texture, and the width of the through groove is the same as the diameter of the wire rope body.
[0013] In a further alternative, multiple protruding threaded tubes are equidistantly distributed on the fastening sleeve, the tube holes of the protruding threaded tubes are threaded, the protruding threaded tubes and the fastening sleeve are designed as an integral unit, and the protruding threaded tubes at the upper and lower ends of the fastening sleeve are symmetrically designed.
[0014] In a further alternative, the rotating handle and the T-shaped key are designed as a single unit. The cross-section of the T-shaped key is T-shaped, and the outer end of the T-shaped key is a disc with an arc-shaped edge. The disc is placed in the T-shaped hole, and the cross-section of the rotating handle is T-shaped.
[0015] In a further alternative, the cross-section of the arc-shaped fastening plate is designed in a "C" shape, and the inner wall of the arc-shaped fastening plate is connected with multiple anti-slip strips by adhesive. The upper and lower sets of the arc-shaped fastening plates are symmetrically designed, and the wire rope joint is fixed by extrusion.
[0016] Compared with the prior art, the present invention has the following beneficial effects:
[0017] The fastening sleeve design securely holds the wire rope body and the folded end of the free end, while the through groove and protruding threaded tube facilitate the installation and adjustment of the rotating handle. The anti-slip texture on the inner wall of the fastening sleeve increases friction during gripping, ensuring a tight fit between the fastening sleeve and the wire rope body, preventing slippage.
[0018] The arc-shaped fastening plate and the rotating handle are connected by a T-key and a T-hole for limiting, allowing the arc-shaped fastening plate to press against the fold of the wire rope body and the free end, achieving a fixation force of varying degrees. This design not only enhances the robustness of the wire rope joint but also allows for adjustment according to different usage requirements, improving the flexibility and applicability of the equipment.
[0019] The threaded part of the rotating handle matches the protruding threaded tube, allowing the rotating handle to be firmly fixed inside the threaded tube and not easily loosened. The integrated design of the rotating handle and the T-key makes operation more convenient. Users can easily adjust the fixing force of the arc-shaped fastener by rotating the rotating handle, improving work efficiency.
[0020] The design of the T-type limit mechanism, namely the cooperation between the T-key and the T-hole, ensures a stable connection between the arc-shaped fastening plate and the rotating handle, preventing the arc-shaped fastening plate from sliding or falling off during the fixing process, thereby ensuring the stability and reliability of the wire rope joint.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figure 1 - Figure 4 As shown, a convenient wire rope for splicing mainly consists of several parts: a wire rope body 1, a loop 2, and a free end 3. One end of the wire rope body 1 is designed as a free end 3, which is bent to form a loop 2 for easy hooking. This loop 2 is located at the hook end of the wire rope, making the entire wire rope more flexible and convenient to use.
[0028] To further enhance the strength of the wire rope joint, a fastening sleeve 6 is fitted over the folded section of the wire rope body 1 and the free end 3. A through groove 7 is provided on the side wall of the fastening sleeve 6 for easy operation. Multiple protruding threaded tubes 8 are provided at the upper and lower ends of the fastening sleeve 6, and a rotating handle 13 is inserted into each protruding threaded tube 8. The rotating handle 13 is equipped with a threaded portion 12 that matches the protruding threaded tube 8, allowing the rotating handle 13 to be securely fixed inside the protruding threaded tube 8. The inner end of the rotating handle 13 is designed with a T-key 11 for easy operation and fixation.
[0029] The upper and lower parts of the through groove 7 are equipped with arc-shaped fastening plates 9, matching the number of rotating handles 13. Each arc-shaped fastening plate 9 has a T-shaped hole 10 at its lower end that matches a T-shaped key 11. The cooperation between the T-shaped key 11 and the T-shaped hole 10 achieves a limiting connection between the arc-shaped fastening plate 9 and the rotating handle 13. Different rotating handles 13 drive the arc-shaped fastening plates 9 connected to them, which can press against the folded joint of the wire rope body 1 and the free end 3, thereby achieving different levels of fixation and ensuring the stability of the wire rope joint.
[0030] A through hole 5 is provided on the end face of the rope loop 2 to facilitate the insertion and fixation of the wire rope. An anti-slip ring 4 is connected to the inner wall of the rope loop 2. The inner wall of the anti-slip ring 4 has anti-slip texture to increase friction and prevent the wire rope from slipping during use. The anti-slip ring 4 perfectly matches the shape of the rope loop 2, ensuring overall stability. The anti-slip ring 4 is made of soft rubber material and is firmly attached to the wire rope body 1 with adhesive.
[0031] The wire rope body 1, the rope sleeve 2, and the free end 3 are designed as a single unit, making the entire wire rope joint more compact and durable. The fastening sleeve 6 has an elliptical ring cross-section and an anti-slip texture on its inner wall, increasing friction when gripping. The width of the through groove 7 is exactly the same as the diameter of the wire rope body 1, ensuring a tight fit between the fastening sleeve 6 and the wire rope body 1.
[0032] Multiple protruding threaded tubes 8 are evenly distributed on the fastening sleeve 6, and each protruding threaded tube 8 has a threaded hole to ensure that the rotating handle 13 can be firmly screwed in. The protruding threaded tubes 8 and the fastening sleeve 6 are integrated into one piece, making the entire structure more robust. The protruding threaded tubes 8 at the upper and lower ends of the fastening sleeve 6 are symmetrically designed, enhancing the overall aesthetics and practicality.
[0033] The rotating handle 13 and the T-shaped key 11 are designed as a single unit, making operation more convenient. The cross-section of the T-shaped key 11 is T-shaped, with the outer end designed as a disc shape and the edge curved for easy gripping and operation. The disc is placed in the T-shaped hole 10, and the cross-section of the rotating handle 13 is also T-shaped, making it easy to use with the T-shaped key 11.
[0034] The arc-shaped fastening plate 9 has a "C"-shaped cross-section, and its inner wall is connected with multiple anti-slip strips by adhesive, which increases the friction with the wire rope body 1 and prevents slippage. The upper and lower sets of arc-shaped fastening plates 9 adopt a symmetrical design, and achieve a firm fixation of the wire rope joint through compression, ensuring the stability and reliability of the wire rope joint during use.
[0035] Bend the free end 3 of the wire rope body 1 to form a loop 2, ensuring that the loop 2 is located at the hook end of the wire rope. Then, slip the fastening sleeve 6 onto the folded portion of the wire rope body 1 and the free end 3. Next, screw the rotating handle 13 into the protruding threaded tube 8 on the fastening sleeve 6 by rotating the threaded portion 12 on the handle 13. The T-shaped key 11 at the inner end of the rotating handle 13 engages with the T-shaped hole 10 at the lower end of the arc-shaped fastening plate 9. By adjusting the position of the rotating handle 13, the arc-shaped fastening plate 9 is pressed against the folded portion of the wire rope body 1 and the free end 3, thus achieving fixation.
[0036] If the size of the through hole 5 on the end face of the rope loop 2 needs to be adjusted to accommodate wire ropes of different diameters, this can be achieved by adjusting the rotating handle 13 on the fastening sleeve 6. First, loosen the rotating handle 13 to reduce the fixing force of the arc-shaped fastening plate 9 on the wire rope body 1 and the free end 3. Then, adjust the curvature of the free end 3 appropriately by enlarging or reducing the size of the through hole 5 as needed, thereby changing the shape of the rope loop 2 and the size of the through hole 5. After adjustment, tighten the rotating handle 13 again. Through the cooperation of the T-key 11 and the T-hole 10, as well as the locking effect of the arc-shaped fastening plate 9, the stability and firmness of the wire rope joint are ensured. The free end 3 can also pass through multiple T-keys 11 and be wound to achieve winding and knotting operations.
