The invention discloses a safety gear triggering structure of a pit-free home elevator. Reversing pulleys are arranged at the two ends of an elastic plate, so that when the elevator works normally, the two ends of an elastic plate move upwards by a certain distance under the pulling force of a mooring rope, and when the mooring rope is broken, the elastic plate does not bear the upward pulling force of the mooring rope any more and moves downwards any more, so that the triggering assembly located below the elastic plate is triggered, the triggering assembly triggers a locking assembly to switch the state, and the lift car is rapidly braked; the triggering assembly drives a trigger piece to trigger the locking assembly in a rotating manner, structures are matched more stably, the safety gear triggering structure avoids accidents and injuries caused by sudden falling of the lift car and passengers in the lift car due to breakage of the mooring rope, the state of the broken rope of the elevator is protected, the injury degree to the passengers in the lift car is greatly reduced, and meanwhile the stability and safety of the elevator are improved.
本申请公开了无底坑家用电梯的安全钳触发结构,该安全钳触发结构通过在弹性板的两端设置换向滑轮,使电梯在正常工作时弹性板的两端经缆绳的拉力而向上具有一段位移,当缆绳断裂时,弹性板不再受到缆绳向上的拉力而向下移动,从而触发位于弹性板下方的触发组件,由触发组件触发锁止组件切换状态,对轿厢进行快速的制动;触发组件通过转动的方式带动触发件触发锁止组件,结构以及结构之间的配合更为稳定,该安全钳触发结构避免轿厢、轿厢内的乘员因缆绳断裂而突然下坠导致发生意外以及损伤,对电梯断绳后的状态进行了保护,大大降低了对轿厢内部乘员的伤害程度,同时也增加了电梯的平稳性以及安全性。
