Abstract

A mechanical lock for building component connection includes a plug element (1) and a lock bod part (2). The plug element (1) includes a plug shell (10), a plug pin structure (11), and a plug transmission structure. The plug pin structure (11) is movably installed in the plug shell (10). The plug transmission structure is in transmission connection with the plug pin structure (11). An end of the plug pin structure (11) is provided with a stop part (110). The lock bod part (2) includes a lock body shell (20), a bracing structure (21), and a lock body transmission structure. An insertion channel (23) matched with the plug pin structure (11) is formed in the lock body shell (20). The lock body transmission structure is in transmission connection with the bracing structure (21).
