LOCKSET
Document Type and Number:
WIPO Patent Application WO/2022/021635
Kind Code:
A1
Abstract:
The present invention relates to a lockset, which comprises a front handle device, a rear handle device, a lock body, a lock core device, a lock tongue and a square core. The lock tongue and the lock core device are arranged in the lock body. The front handle device comprises a front handle, and the front handle is arranged at one side of the lock body. The rear handle device comprises a rear handle, and the rear handle is arranged at the other side of the lock body. The lock core device comprises a push arm for driving the lock tongue to move, a front lock piece for driving the push arm to move, a rear lock piece for driving the push arm to move, a limiting rod for locking the movement of the front lock piece, and a limiting piece for locking the movement of the limiting rod. The front handle drives the front lock piece by means of the square core to rotate, and the rear handle drives the rear lock piece by means of the square core to rotate. When the rear handle is lifted up, the front lock piece cannot move, causing the front handle to be unable to rotate, thus implementing reverse locking. When the rear handle is pressed down, both the front handle and the rear handle may rotate freely and drive the lock tongue to move, thus unlocking.
