Back locking structure and door lock
The invention discloses a back locking structure and a door lock. The back locking structure comprises a first shell, a second shell, a rotating wheel and a back locking piece. The first shell is provided with a first through hole, the edge of the first through hole is provided with a first notch, the second shell is provided with a second through hole, the edge of the second through hole is provided with a second notch, the rotating wheel is rotationally connected between the first through hole and the second through hole, and the edge of the rotating wheel is provided with a notch groove; when the counter locking piece clamps the first notch, the notch groove and the second notch at the same time, counter locking is achieved. According to the door lock, the first notch, the notch groove and the second notch are clamped at the same time through the counter locking piece to achieve counter locking, the counter locking structure of a conventional door lock is simplified, the product cost is reduced, and the product assembling efficiency is improved.
本发明公开了一种反锁结构及门锁；所述反锁结构，包括第一壳体、第二壳体、转轮及反锁件；第一壳体设有第一通孔，第一通孔的边缘设有第一缺口，第二壳体设有第二通孔，第二通孔的边缘设有第二缺口，转轮转动连接于第一通孔与第二通孔之间，转轮的边缘设有缺口槽；当反锁件同时卡住第一缺口、缺口槽及第二缺口时，以实现反锁。本发明通过反锁件同时卡住第一缺口、缺口槽及第二缺口，以实现反锁，简化了常规门锁的反锁结构，降低了产品成本以及提升了产品的组装效率。
