Manual latch bolt and safety bolt linkage structure
The invention discloses a manual latch bolt and safety bolt linkage structure. The linkage structure is characterized by comprising a lock shell, a safety bolt, a safety shifting block, a push plate,a latch bolt and a shifting piece set synchronously rotating with a lever handle, the shifting piece set is linked with the latch bolt and the push plate, the push plate is linked with the safety shifting block, external force drives the safety shifting block to rotate to push the safety bolt to move linearly and extend out of the lock shell, a locking groove is formed in the tail portion of the safety bolt, the safety shifting block falls into the locking groove to limit linear retraction of the safety bolt, a linkage piece is arranged on the push plate, the linkage piece drives the safety shifting block to rotate in one direction and drives the safety bolt to retract into the lock shell, and the latch bolt and the safety bolt retract at the same time. The linkage structure has the advantages that unlocking of the safety bolt is achieved by means of a lever handle shifting piece, the latch bolt and the safety bolt can retract into the lock shell at the same time, when a door is opened, the door can be opened only by rotating the lever handle, and therefore, more convenience is achieved.
本发明公开了手动斜舌与保险舌的联动结构，特点是包括锁壳、保险舌、保险拨头、推板、斜舌、与执手同步旋转的拨件组，拨件组分别与斜舌和推板联动，推板与保险拨头联动，外力驱动保险拨头旋转，推动保险舌直线运动且向锁壳外伸展，保险舌尾部设有锁止槽，保险拨头落入锁止槽中限制保险舌直线回退，推板上设有联动件，联动件驱动保险拨头单向转动且驱动保险舌回缩至锁壳内，斜舌与保险舌同时回缩，优点是可以通过执手拨件来实现对保险舌的解锁，使斜舌与保险舌能同时回缩至锁壳内，开门时只需转动执手即可开门，更加方便。
