AI Technical Summary
The existing fall protection structure has separate support mechanisms and fall protection nets, which are inconvenient to install and difficult to store efficiently after use.
Design a structure including a support base, a support arm, and a fall protection net. The support base is provided with a side groove and a swing arm groove. The support arm is connected by a pin. A telescopic rod and a winding rod are sleeved on the support arm. The fall protection net is unfolded by a motor driven by the winding rod, and can be quickly unfolded and retracted by a positioning screw and a limiting screw.
It enables the rapid deployment and efficient storage of fall protection nets, improving installation efficiency and space utilization.
