Abstract
A connection lock for prefabricated components includes an auxiliary part and a main part which are each provided with a fixing structure for connecting with a prefabricated component in an anchoring fit manner. The auxiliary part includes an auxiliary part body, an auxiliary part transmission structure, and a lock pin structure which is movably mounted to the auxiliary part body. The auxiliary part transmission structure is in transmission fit with the lock pin structure. The main part includes a main part body, a main part transmission structure, and a locking structure. An inserting channel fitted with the lock pin structure is formed in the main part body. The locking structure is adjustably mounted in the main part body. The main part transmission structure is in transmission fit with the locking structure. It is rapid and convenient to operate, and the construction efficiency is higher than traditional construction methods.
