[0002] At present, when the public security or military conducts live-fire shooting training, bullet-proof walls are usually needed for live-fire interception. Existing bullet-proof walls generally use steel plates as the base of the wall, and then a layer of rubber plates is set on the steel plates to block the rebound of bullet slag. However, after the traditional bullet-proof wall is subjected to live-fire shooting, the bullet will pass through the rubber plate and get stuck directly on the steel plate, making it inconvenient to clean the bullet, and it is easy to reduce the bullet-proof wall's bullet-receiving area. Utility Model Content

[0003] The utility model discloses a mobile bulletproof wall L-shaped corner which can be quickly constructed in an indoor training environment. The utility model mainly solves the problem that after being shot with live ammunition, the bullets of the traditional bulletproof wall will be directly stuck on the steel plate after passing through the rubber plate, which makes it inconvenient to clean the bullets.
