The invention provides an automatic lock catch for an ultrathin elevator lock. The automatic lock catch comprises a crank arm ratchet wheel, a lock column and a linkage assembly, wherein the linkage assembly communicates with the crank arm ratchet wheel; and the linkage assembly can drive the crank arm ratchet wheel to clamp onto the lock column. The crank arm ratchet wheel and a limiting wrench are arranged, so that the automatic lock catch is more compact in structure and is higher in space utilization rate in comparison with a lock catch structure in the prior art, and saves space of a lockbody; a right arm of the limiting wrench is blocked into blocking teeth of the crank arm ratchet wheel, so that the crank arm ratchet wheel can be prevented from freely rotating to affect locking effect; and the blocking teeth are arranged, so that the crank arm ratchet wheel is provided with multiple clamping positions, and therefore, the automatic lock catch is higher in practicability.

    本发明提供了一种超薄电梯锁的自动锁扣,包括曲臂棘轮、锁柱、和联动组件,所述联动组件与所述曲臂棘轮相连通,所述联动组件能够驱动所述曲臂棘轮卡紧在所述锁柱上,通过曲臂棘轮和限位扳手的设置,相较于现有技术中的锁扣结构更加紧凑,空间利用率更高,节约了锁体的空间,同时通过限位扳手的右臂卡在曲臂棘轮的卡齿中,可以避免曲臂棘轮自由转动影响锁紧效果,同时卡齿的设置使得曲臂棘轮具有多个卡紧位置,具有较强的实用性。
