Title:
MECHANICAL LOCK FOR JOINING BUILDING COMPONENTS
Document Type and Number:
WIPO Patent Application WO/2022/099874
Kind Code:
A1
Abstract:
A mechanical lock for joining building components, comprising a plug assembly (1) and a lock body assembly (2). The plug assembly (1) comprises a plug housing (10), a latch structure (11) and a plug transmission structure. The latch structure (11) is movably mounted on the plug housing (10), the plug transmission structure is in transmission connection with the latch structure (11), and one end of the latch structure (11) is provided with a stop part (110). The lock body (2) comprises a lock body housing (20), a stretching structure (21) and a lock body transmission structure. The lock body housing (20) is provided with an insertion passage (23) which cooperates with the latch structure (11). The lock body transmission structure is in transmission connection with the stretching structure (21). The stretching structure (21) has a jacking part which moves in the extension direction of the insertion passage (23). The jacking part is fitted with and retains the stop part (110) of the latch structure (11). Since the jacking part retains the stop part (110) of the latch structure (11) and prevents the latch structure (11) from exiting the insertion passage (23), an effective connection is formed between the plug assembly (1) and the lock body assembly (2) such that the two assemblies are firmly and reliably connected.
