THREADFORM LOCKING DEVICE AND METHODS |
摘要 |
Locking devices and methods are described. The locking device includes a non-resilient locking threadform that is expandable and a threaded expander. The threadform includes a threaded exterior portion and an axially-oriented, threaded interior recess at a proximal end of the threadform. The threaded exterior portion has a length and is configured to connect two articles in an axial direction. The threaded expander has a threaded exterior that is oversized relative to the threaded interior recess so as to expand the threaded exterior portion radially as the threaded expander is positioned in the threaded interior recess. |

1. A locking device, comprising:
a non-resilient locking threadform that comprises a threaded exterior portion having a length, being configured to connect and retain two adjacent external articles in an axial direction, and having an unexpanded state and an expanded state, and an axially-oriented, threaded interior recess at a proximal end of the threadform; and a threaded expander having a threaded exterior and being oversized relative to the threaded interior recess so as to expand the threaded exterior portion radially from the unexpanded state to the expanded state as the threaded expander is positioned in the threaded interior recess. |
