PC Conbination shield

The shield is composed of two pieces: a 1600 × 550 × 3.5 large shield and a 1200 × 550 × 3.5 small shield. Both large and small shields are composed of shield body, reinforcing layer, foam liner, grip, handle, etc. The shield bodies and reinforcement layers of both the large and small shields are integrally formed by hot pressing PC boards. There is a semi-circular overlap surface on each side of the left and right sides, which allows multiple shields to overlap with each other to form a shield wall. The lower end of the small shield reinforcement layer has a V-shaped slot placed at the upper end of the large shield, forming an upper and lower protective connection. Multiple combination riot shields can be connected to each other using semi-circular grooves formed on both sides of the width to form a row of shield walls. Each set of combinations is operated simultaneously by two people, one in front and one behind. The shield wall resists attacks from external knives, sticks, rods, stones, etc., effectively covering the advance, evacuation, and obstruction of the enemy's advances behind.
