AI Technical Summary
Existing elevators lack multi-stage cushioning during a fall, resulting in a huge impact force that threatens personal safety.
An elevator fall prevention safety mechanism was designed, including a buffer arm, a buffer block, a buffer spring, and a guide groove structure. By sliding the buffer arm in the guide hole and sliding the buffer block in and out of the buffer hole, combined with the rebound force of the multi-stage buffer spring, multi-stage buffering is achieved to reduce the impact of falling.
It effectively reduces the impact force when the elevator falls, ensures passenger safety, avoids direct breakage caused by strong impact, and achieves a multi-level buffering effect.
