Title:
LOCK HAVING CLUTCH DRIVE MECHANISM
Document Type and Number:
WIPO Patent Application WO/2023/123594
Kind Code:
A1
Abstract:
A lock (100) having a clutch drive mechanism (50). The clutch drive mechanism (50) comprises a drive input portion (40), a clutch assembly (51), a deadbolt transmission assembly (55), and a latch bolt transmission assembly (54). One end of the drive input portion (40) is driven, and the other end is connected to the clutch assembly (51); one end of the clutch assembly (51) is driven, and the other end thereof drives one of the deadbolt transmission assembly (55) or the latch bolt transmission assembly (54). One end of the deadbolt transmission assembly (55) is driven in a first direction, and the other end implements door locking by a deadbolt (72); and one end of the latch bolt transmission assembly (54) is driven in a second direction, and the other end implements door opening. Therefore, the deadbolt (72) of the lock can be mechanically double locked without a key, and a latch bolt (81) still maintains a normally open mode without using a key every time the deadbolt (72) is double locked, and only when the double locking of the deadbolt (72) is released does a key or motor need to be used for driving, thereby greatly reducing the time required for double locking, and making the use of the lock more convenient and faster.
