Title:
SHACKLE FOR PREVENTING SCREW-BOLT FROM BEING LOOSENED BY REVERSE ROTATION
Document Type and Number:
WIPO Patent Application WO/2016/153196
Kind Code:
A1
Abstract:
The present invention relates to a shackle for preventing a screw-bolt from being loosened by reverse rotation and, more specifically, to a shackle for preventing a screw-bolt from being loosened by reverse rotation that can prevent a heavy object from falling on account of the separation of the screw-bolt from a shackle main body by reverse rotation, which is caused by continuous vibration or external impact when a hoist lifts the heavy object, by installing and using a rotation control device that prevents the reverse rotation of the screw-bolt. The shackle for preventing a screw-bolt from being loosened by reverse rotation, according to the present invention, comprises: a shackle main body having insertion holes formed in opposite sides thereof; a screw-bolt inserted into the insertion holes that are formed in the shackle main body; and a rotation control device that is fixedly coupled to the outside of the shackle main body and selectively restricts the rotational direction in which the screw-bolt is rotated by an external force.
