[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0025] As Figures 1-4 shown, a thornless wire rope sling includes a sling body 1, and the sling body 1 is formed by twisting six strands of wire ropes 3 and one strand of rope core 4 together. The part where the ends of the sling body 1 are twisted together is divided into two identical wire strands. The two wire strands pass through the circle in sequence around the separated ends and are inserted into the sling body 1 according to the method of pressing two and inserting one to form a socket 2. Two sockets 2 are sleeved with a connection component for connecting a hook.

[0026] The connection component includes a U-shaped rod 6 and a limiting rod 8. The U-shaped rod 6 is sleeved outside the socket 2. One end of the U-shaped rod 6 is provided with an installation groove 7 for installing the limiting rod 8. The limiting rod 8 is rotatably connected to the installation groove 7 through a rotating shaft. One end of the U-shaped rod 6 is provided with a docking groove 10 that cooperates with the limiting rod 8. A connection bolt 11 is threadedly penetrated through the inner bottom surface of the docking groove 10. A threaded hole 12 that cooperates with the connection bolt 11 is provided at the end of the limiting rod 8. When in use, the staff first loosens the connection bolt 11 to release the fixation of the limiting rod 8, and then the limiting rod 8 can be flipped open. The connection ring of the external hook is sleeved on the limiting rod 8, and then the limiting rod 8 is flipped closed. The connection bolt 11 is screwed into the threaded hole 12 at the end of the limiting rod 8 to realize the fixation of the limiting rod 8, that is, to realize the rapid installation of the external hook.

[0027] Further, a threaded ring 9 is sleeved outside the limiting rod 8, and a threaded circle that cooperates with the threaded ring 9 is provided on the outer surface of the limiting rod 8 near the rotating shaft. When the limiting rod 8 is fixed, by rotating the threaded ring 9, the threaded ring 9 abuts against the outer edge of the installation groove 7, further restricting the deflection of the limiting rod 8, that is, achieving the effect of double limiting constraints on the limiting rod 8, and effectively ensuring the stability of the limiting rod 8 after fixation.

[0028] Further, an arc-shaped plate 14 is fixedly provided on the outside of the U-shaped rod 6, and two L-shaped reinforcing plates 13 that cooperate with the outer edge of the installation groove 7 are symmetrically provided at the lower end of the arc-shaped plate 14. By providing the L-shaped reinforcing plates 13, the threaded ring 9 is screwed tightly against the outer surface of the L-shaped reinforcing plate 13, effectively avoiding the low thickness at the edge of the installation groove 7 from being easily deformed under pressure.

[0029] Further, one end of the rotating shaft movably penetrates outside the installation groove 7 and is rotatably connected to the L-shaped reinforcing plate 13, further ensuring the stability of the rotating connection of the rotating shaft of the limiting rod 8.

[0030] Furthermore, protective cushion rings 5 are fixedly arranged inside both of the two cable sleeves 2, achieving the effect of protecting the cable sleeves 2, avoiding wear of the cable sleeves 2, and further improving the service life of the sling body 1.

[0031] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
