Door lock capable of being automatically locked
The invention provided a door lock capable of being automatically locked. The door lock comprises a shell, a dead bolt unit, a latch bolt unit, an anti-picking bolt unit and a linkage unit; the dead bolt unit comprises a dead bolt and a positioning handle; the latch bolt unit comprises a latch bolt and an actuating handle; the anti-picking bolt unit comprises an anti-picking bolt; the linkage unitcomprises an unlocking sheet, a linkage plate and a baffle; and the linkage plate is provided with a rear arm. When the door lock is moved from a door opening state to a door locking state, the latchbolt and the anti-picking bolt touch a door frame and move backwards to enable the rear arm to swing upwards in a pivoted mode; and when the latch bolt penetrates out of the shell again, the actuating handle pushes and abuts against the rear arm of the linkage plate and pushes the linkage plate and the unlocking sheet to move forwards, so that the baffle is separated from the positioning handle,the dead bolt penetrates out of the shell and is automatically locked, and the use safety can be improved.
一种可自动上锁的门锁，包含外壳、方舌单元、斜舌单元、防撬舌单元，及连动单元。所述方舌单元包括方舌及定位柄。所述斜舌单元包括斜舌及作动柄。所述防撬舌单元包括防撬舌。所述连动单元包括解锁片、连动板，及挡板。所述连动板具有后臂。所述门锁由开门状态移动至锁门状态的过程中，所述斜舌与所述防撬舌碰到门框而朝后移动使所述后臂向上枢摆，所述斜舌再次穿出所述外壳时，所述作动柄推抵于所述连动板的后臂并推动所述连动板与所述解锁片朝前移动使所述挡板脱离所述定位柄，而使所述方舌穿出所述外壳而自动上锁，能够提高使用安全性。
