Idling type back locking lock body
The invention discloses an idling type back locking lock body which comprises a lock shell and a spring bolt, a spring bolt driving piece matched with the spring bolt is arranged on the lock shell, and a rotating driving piece matched with a square shaft is further arranged on the lock shell. A linkage rod and a linkage torsional spring are arranged on the rotary driving piece, and the linkage torsional spring can press the linkage rod to be matched with the linkage concave part of the spring bolt driving piece, so that the rotary driving piece can push the spring bolt driving piece to rotate through the linkage rod; a back locking driving piece matched with the back locking strip is further arranged on the rotary driving piece, the back locking driving piece can rotate relative to the rotary driving piece, the linkage rod is pushed by the back locking driving piece through the protruding part to be separated from the linkage concave part, at the moment, the rotary driving piece cannot push the spring bolt driving piece to rotate through the linkage rod, and the back locking function is achieved. The lock body is simpler in structure and more compact in size.
本发明公开了一种空转式反锁锁体，包括锁壳和锁舌，在锁壳上设置有与锁舌相配合的锁舌驱动片，所述在锁壳上还设置有与方轴相配合旋转驱动件；所述旋转驱动件上设置有联动杆和联动扭簧，所述联动扭簧能按压联动杆与锁舌驱动片的联动凹陷部相配合，使得所述旋转驱动件能通过联动杆推动锁舌驱动片旋转；在旋转驱动件上还设置有与反锁条相配合的反锁驱动片，所述反锁驱动片能相对旋转驱动件旋转，并且其通过凸起部推动联动杆与联动凹陷部相分离，此时所述旋转驱动件无法通过联动杆推动锁舌驱动片旋转，实现反锁功能，该锁体结构更加简单，体积更加紧凑。
