Fusible link comprising damper and backstop

摘要

A link including a rod with a connection member at each end with an axis passing through both connection members. The rod includes a fusible zone as a narrow section lying between a first rod portion connected to a first connection member and a second rod portion connected to a second connection member. The fusible zone breaks when tensile force to which the link is subjected is greater than a predetermined value. The two rod portions are inseparable in event of the fusible zone breaking by a cylinder coaxial about the axis and secured to the first rod portion, and having an end wall through which the second rod portion passes. The second rod portion includes a collar that can slide into the cylinder if the fusible zone breaks. The inside wall of the cylinder includes teeth configured to be broken by the collar if the fusible zone breaks.
