Abstract

This invention relates to a convenient lock cylinder and lock head connection structure, comprising a lock head and a lock head connected to the lock head. The lock head includes a lock housing, which includes an inner part for mounting to the inside of the door and an outer part for mounting to the outside of the door. The lock head includes a connecting shaft for connecting to the lock head. A connecting hole is provided on one side of the outer part of the lock housing. A rotary locking mechanism for locking / unlocking the connecting shaft and the lock housing is provided between the connecting shaft and the lock housing. The connecting shaft is pluggably connected to the connecting hole via the rotary locking mechanism. The rotary locking mechanism can be rotated from the inner part side to lock / unlock the connecting shaft and the lock housing. This invention solves the problem of the lock head not being directly replaceable by providing a rotary locking mechanism between the connecting shaft of the lock head and the lock housing of the lock head, allowing the connecting shaft of the lock head to be pluggably connected to the connecting hole. Locking and unlocking of the connecting shaft and the lock housing can be achieved simply by rotating the rotary locking mechanism, thus solving the problem of the lock head not being directly replaceable.
