WIPO Patent Application WO/2021/179537
Kind Code:
A1
Abstract:
A latch bolt sliding assistance apparatus, comprising a lock box (10), a latch bolt mechanism (20) and rolling pieces; the latch bolt mechanism (20) comprises a latch bolt (21), a latch bolt hole for the latch bolt (21) to pass through is arranged on a side plate of the lock box (10), the rolling pieces are rotatably connected to the latch bolt mechanism (20) and cooperate with the lock box (10) in a rolling manner, and when the latch bolt (21) moves back and forth along the latch bolt hole, the rolling pieces are connected to the lock box (10) in a rolling manner; when the latch bolt (21) retracts into the lock box (10), the rolling pieces cooperate with the lock box (10) in a rolling manner, thereby reducing friction between the latch bolt (21) and the lock box (10), and facilitating unlocking; when the latch bolt (21) extends out from the lock box (10), the rolling pieces cooperate with the lock box (10) in a rolling manner, thereby reducing friction between the latch bolt (21) and the lock box (10), and facilitating locking. Since the rolling pieces cooperate with the lock box (10) in a rolling manner, for a fully automatic lock body, movement friction of the latch bolt (21) is reduced, thereby reducing current consumption.
