Title:
BUCKLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/202317
Kind Code:
A1
Abstract:
A buckle device, comprising a male buckle (10), a female buckle (20), a snap-fit member (30), and an elastic unlock component (40). The elastic unlock component (40) is movably provided in the female buckle (20), and is provided with an unlock operation portion (43), an elastic portion (44), an ejection portion (41), and a snap-fit actuation portion (42); the elastic portion (44) can act on the ejection portion (41); the ejection portion (41) can move to a binding portion formed between a lock tongue (12) and the female buckle (20); the snap-fit actuation portion (42) can actuate the snap-fit member (30); when the unlock operation portion (43) moves in an unlock direction (A) to perform unlock operation, the elastic portion (44) is pressed, and the ejection portion (41) has, under the action of the elastic portion (44), the trend of driving the lock tongue (12) to move out of a lock hole (221); and when the unlock operation portion (43) moves to the snap-fit actuation portion (42) to actuate the snap-fit member (30) such that the snap-fit member (30) is disengaged from the lock tongue (12), the ejection portion (41) can drive the lock tongue (12) to move out of the lock hole (221). When the buckle device is unlocked, the snap-fit member (30) does not immediately move out of the lock tongue (12) along with the operation of the elastic unlock component (40), but moves out of the lock tongue (12) to be disengaged from the lock tongue (12) when an opening force reaches a certain degree, so that accidental unlocking can be effectively avoided, thereby improving the safety.
