Abstract

The invention belongs to the technical field of quick locking, and relates to a three-lock clamp locking mechanism with a redundancy design. The locking mechanism is composed of four hinge pins, threelock clamps, a pair of auxiliary lock clamps and three connecting pieces. The relative positioned of the three connecting pieces connecting the hinge pins are distributed in a triangular mode, and are coplanar with center faces of the three lock clamps at the corresponding positions. The locked lock clamps can cover the connecting pieces at the corresponding positions. Square grooves are formed in the centers of the root positions of the auxiliary lock clamps. The three lock clamps are adopted to achieve locking of the locking mechanism. A redundancy protection structure is arranged, and reliability of the locking structure is better improved.

Description

technical field [0001] The invention belongs to the technical field of fast locking, and relates to a three-lock clamp locking mechanism with redundant design. Background technique [0002] The clamp-type locking structure is widely used in engineering applications. The principle of the common locking structure is the same. The locking forms include double-lock structure, three-lock structure and four-lock structure. On the premise of convenient operation, the greater the number of locks, the higher the reliability. For aviation products used in important parts, there is a requirement for redundant design. When one part fails, other parts can work normally without affecting product performance, which minimizes the risk of product failure. Therefore, for the clamp locking structure, the lock locking method alone cannot fully meet the requirements. Generally, the connection components with redundant design use the combination of locks and auxiliary locks for redundant locki...
