Description

Technical Field

[0001] The utility model relates to the field of bow-shaped shackles, in particular to a high-strength bow-shaped shackle. Background Art

[0002] The bow shackle is a connector used for lifting and pulling. It is called a bow shackle because of its shape similar to a bow and arrow. The bow shackle is also often called a horseshoe shackle or a B-type shackle. The bow shackle is widely used in various industries such as electricity, metallurgy, petroleum, machinery, railways, chemicals, ports, mining, and construction.

[0003] The bow shackle is made of bent U-shaped metal with threaded holes or pin holes at both ends for connecting hooks, chains or ropes, etc. This design makes the bow shackle have a higher load-bearing capacity and can carry different weights according to different specifications and models.

[0004] Existing bow shackles are usually connected to the shackle rod through a nut to achieve connection with the bow shackle body. However, after the bow shackle has been used for a period of time, the nut is likely to loosen, and the connection between the shackle rod and the bow shackle body will become loose, which may easily cause the shackle rod to separate from the bow shackle body, and in serious cases, may even cause a safety accident.
