The invention discloses an auxiliary triggering device of pit-free home elevator safety tongs. The auxiliary triggering device comprises a triggering assembly, a locking assembly and a connecting rodassembly, wherein the triggering assembly comprises a tensioning wheel and an elastic reset piece, a cable is pressed on the tensioning wheel to enable the elastic reset piece to be compressed to be in an energy storage state, and then the locking assembly is located at a non-braking position; and the cable is separated from the tensioning wheel so that the elastic reset piece can release the stored elastic potential energy, then the locking assembly can be switched from the non-braking position to the braking position, the locking assembly can clamp a guide rail, and the situation that a carsuddenly falls down due to breakage of the cable is prevented. By means of the structure, the safety and stability of a home elevator in the running process can be improved, accidents and injuries caused by sudden falling of the car and passengers in the car due to breakage of the cable are prevented, the state of the elevator after cable breaking is protected, and the injury degree to the passengers in the car is greatly reduced.

    本发明公开了一种无底坑家用电梯安全钳的辅助触发装置,包括触发组件、锁止组件和连杆组件。其中,触发组件包括张紧轮和弹性复位件,缆绳压持于张紧轮以使弹性复位件压缩处于蓄能状态,进而使得锁止组件处于非制动位置;缆绳与张紧轮分离以使弹性复位件将存储的弹性势能释放,进而使得锁止组件由非制动位置向制动位置切换,从而实现锁止组件对于导轨的夹持,防止因缆绳断裂导致轿厢突然下坠。这种结构能够提升家用电梯运行过程的安全性和稳定性,防止轿厢、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。
