Safety protective net of playground

Abstract

The invention belongs to the technical field of protective nets, and particularly provides a safety protective net of a playground. T-shaped sliding grooves are formed in the vertical directions of the two side walls of U-shaped mounting frames; mounting clamping grooves are formed in the horizontal direction of a mounting cross beam, and the U-shaped mounting frames are clamped into the mountingclamping grooves; elastic net protecting plates are slidingly inserted into the U-shaped mounting frames through T-shaped inserting strips arranged in the vertical directions of the two sides; an airguide pipe is inserted into the horizontal direction in a fixing cross beam; expansion cavities are formed in the elastic net protecting plates, connecting air pipes are inserted into the vertical directions in limiting inserting strips, the connecting air pipes communicate with the air guide pipe, and air control valves are arranged at the bottom ends of the connecting air pipes; air guide holesare formed in one side walls of the connecting air pipes; and air inlets are formed in the side walls of the U-shaped mounting frames and the limiting inserting strips. The situations that when an athlete does exercise, the athlete hits against a safety protective net of the playground due to the inertia of exercise of himself / herself, then the athlete is hurt, and then the safety of exercise of the athlete is affected are effectively avoided.
