AI Technical Summary
The complex transmission mechanism of existing push-pull door locks results in a large lock thickness, and the increased length of the lock cylinder due to high security requirements further increases the lock thickness.
The design employs a lock cylinder seat and a lock hook seat, connected by a snap-fit device. The rotation of the lock cylinder drives the lever device, which in turn drives the lifting device to rise and fall. The lifting is converted into the rotation of the lock hook through a lever mechanism, simplifying the transmission structure.
This design achieves a slimmer and lighter sliding door lock, simplifies the structure of the transmission mechanism, and improves security.
