Single-bolt counter-locking lock body
The invention discloses a single-bolt counter-locking lock body which comprises a lock shell, a bolt with a lock rod is arranged on a bolt hole of the lock shell, a bolt driving part matched with the bolt is arranged in the lock shell and can push the bolt to retract into the lock shell, and a counter-locking device for limiting rotation of the bolt driving part is further arranged in a spin lock shell. The back locking device comprises a blocking piece, a blocking torsional spring and a back locking driving piece matched with the back locking lock cylinder, one end of the blocking piece is rotationally arranged on the lock body through a rotating shaft, and the other end of the blocking piece abuts against the back locking driving piece through the blocking torsional spring; the back lock driving piece can push the blocking piece to swing upwards to be matched with the lock groove of the spring bolt driving piece, and the spring bolt driving piece is locked. Therefore, the back locking function is achieved by directly limiting rotation of the spring bolt driving piece through the back locking device, a back locking spring bolt does not need to be added, and the structure is simplified.
本发明公开了一种单锁舌反锁锁体，包括锁壳，所述锁壳的锁舌孔上设置有一个带有锁杆的锁舌，在锁壳内设有与锁舌相配合的锁舌驱动件，所述锁舌驱动件能推动锁舌缩回锁壳内，所述旋锁壳内还设有限制锁舌驱动件旋转的反锁装置；所述反锁装置包括阻挡件、阻挡扭簧以及与反锁锁芯相配合的反锁驱动件，所述阻挡件的一端部通过转轴转动设置在锁体上，另一端部通过阻挡扭簧抵靠在反锁驱动件上；所述反锁驱动件能推动阻挡件向上摆动与锁舌驱动件的锁槽相配合，将锁舌驱动件进行锁定。因此本发明通过反锁装置直接限制限制锁舌驱动件旋转来实现反锁功能，而不需要增加反锁锁舌，简化结构。
