Benefits of technology

This innovation improves upon existing structures for ensuring secure connections between parts without being affected by external factors like weather conditions during construction work. It also prevents loose threads from getting stuck due to high temperatures that could damage sensitive components such as electronic devices used inside buildings.

Problems solved by technology

This patents describes different ways to secure connections between parts that can move relative easily during normal operation or accidentally due to factors like external shock loading. However, there may still exist situations where these connections become loose over time without being able to detect any issues with them. These technical problem addressed by this patented technology include improving resistance against frictional movement caused by environmental conditions (vibrations) while also maintaining safety standards when connecting components together through mechanical means.

Abstract

The invention discloses a novel lock bolt comprising a screw, a first locking member and a second locking member. The first locking member comprises a first nut, a boss and a small taper expansion sleeve, the first nut, the boss and the small taper expansion sleeve are integrally arranged, the outer wall of the boss is provided with a first external thread, and the inner wall of the first lockingmember is provided with a first internal thread matched with the screw; and the second locking member comprises a second nut, the two ends of the inner wall of the second nut are provided with a second internal thread and a third internal thread which are matched with the first external thread and the screw correspondingly, the middle portion of the inner wall of the second nut is provided with aninner tapered surface in interference fit with the small taper expansion sleeve, and the axes of the second nut and the first nut are eccentric. The novel lock bolt is of a new structure, ensures bolt strength, is more reliable in loosening prevention and can solve the problem about safe connection of equipment with large vibration or large temperature differences.
