Abstract

An anti-torque safety hook includes a main body, a gate member, and a detent member. The main body has a hook opening passing through the front and back sides thereof, a passage communicating to the right side of the hook opening, a female buckle arranged on the passage, a connection unit arranged below the hook opening, and an energy absorption area arranged on the left side of the hook opening. The gate member has a first end mounted on the main body and a second end comprising a male buckle, adapted for detachably coupled with the female buckle, so as to allow the gate member to open and close the passage. The detent member is coupled on the main body and maintained at a first position, so as for ensuring that the gate member closes the passage, while when the detent member is operated and switched to a second position, the safety is disarmed. The present invention mainly utilizes the detent member to ensure the gate member to close the passage. When the main body bears the designated torque, the energy absorption area allows the main body to distort in response while the gate member may still close the passage, so as to prevent the risk of decoupling and in order to meet the standard of ANSI/ASSP Z359.12-2019.
