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 splashes. However, the rubber bricks on the traditional bullet-proof wall are generally spliced. When live-fire shooting is carried out, there will be gaps between two adjacent rubber bricks. When the bullet passes through the gaps between adjacent rubber bricks, there is no buffering effect on the bullet. The impact of the bullet on the steel plate will be greater, and the effect of suppressing the splash of shrapnel will be seriously reduced. Utility Model Content

The bulletproof steel plate comprises a T-shaped structure, wherein the outer surfaces of the bulletproof steel plate are respectively provided with steel structure frames, and the sides of the steel structure frames away from the bulletproof steel plate are provided with wooden boards, and the sides of the wooden boards away from the steel structure frames are provided with an anti-bouncing rubber brick layer, wherein the anti-bouncing rubber brick layer comprises a plurality of anti-bouncing rubber bricks spliced ​​with each other, and the two adjacent edges of the anti-bouncing rubber brick are respectively provided with a plurality of outwardly convex first side splicing blocks, and adjacent first side splicing blocks are spaced to form splicing grooves, and the other two adjacent edges of the anti-bouncing rubber brick are respectively provided with second side splicing blocks which match the splicing grooves, so that the second side splicing blocks of the anti-bouncing rubber bricks are embedded in the splicing grooves of the adjacent anti-bouncing rubber bricks.

[0006] In one embodiment, the side of the bulletproof steel plate facing the wooden board, the inner surface of the steel structure frame and the side of the wooden board facing the bulletproof steel plate surround a bullet collecting chamber, and the bottom of the steel structure frame is penetrated by a bullet discharge port communicating with the bullet collecting chamber.

[0007] In one embodiment, the top edge of the steel structure frame is provided with fixing holes for splicing.

[0008] In one embodiment, the anti-bouncing rubber brick has a thickness of 50 mm.

[0009] In one embodiment, the thickness of the first side joining block and the second side joining block is 16 mm.

[0010] In one embodiment, the wooden board is a flame retardant wooden board.

[0011] In one embodiment, universal casters and foot cups are provided at the bottom of the steel structure frame.

[0012] The advantages or beneficial effects of the above technical solution at least include: when conducting live-fire shooting training, since the T-shaped corner of the mobile bulletproof wall includes a bulletproof steel plate with a T-shaped structure, the outer surfaces of the bulletproof steel plates are respectively provided with steel structure frames, and wooden boards are provided on the side of the steel structure frames away from the bulletproof steel plates, and an anti-bouncing rubber brick layer is provided on the side of the wooden boards away from the steel structure frames, and the anti-bouncing rubber brick layer includes a plurality of anti-bouncing rubber bricks spliced ​​with each other, and the two adjacent edges of the anti-bouncing rubber bricks are respectively provided with a plurality of outwardly convex first side splicing blocks, and adjacent first side splicing blocks are spaced to form a splicing groove, and the other two adjacent edges of the anti-bouncing rubber bricks are respectively provided with second splicing blocks matching the splicing groove. The side splicing block makes the second side splicing block of the anti-ricochet rubber brick embedded in the splicing groove of the adjacent anti-ricochet rubber brick. Therefore, under the setting of the first side splicing block and the second side splicing block at the edge of the adjacent anti-ricochet rubber bricks, when the live bullet passes through the gap between the adjacent anti-ricochet rubber bricks, the first side splicing block and the second side splicing block will have a buffering effect on the bullet, so that the bullet can reduce the impact force on the steel plate when passing through the gap between the adjacent anti-ricochet rubber bricks, so as to ensure the effect of suppressing the splash of shrapnel at this position. At the same time, under the action of the anti-ricochet rubber bricks being spliced ​​with each other, the stability of the connection between the anti-ricochet rubber bricks can be improved to ensure the buffering effect of the anti-ricochet rubber bricks.

[0033] See also Figure 1 , Figure 3 and Figure 4 The embodiment of the utility model provides a mobile bulletproof wall T-shaped corner for rapid construction in an indoor training environment, including a bulletproof steel plate 1 of a T-shaped structure, a steel structure frame 2 is respectively arranged on the outer surface of the bulletproof steel plate 1, a wooden board 3 is arranged on the side of the steel structure frame 2 away from the bulletproof steel plate 1, and an anti-jump rubber brick layer 5 is arranged on the side of the wooden board 3 away from the steel structure frame 2, and the anti-jump rubber brick layer 5 includes a plurality of mutually spliced ​​anti-jump rubber bricks 51, and the two adjacent edges of the anti-jump rubber brick 51 are respectively provided with a plurality of outwardly convex first side splicing blocks 52, and adjacent first side splicing blocks 52 are spaced to form splicing grooves 53, and the other two adjacent edges of the anti-jump rubber brick 51 are respectively provided with second side splicing blocks 54 matching the splicing grooves 53, so that the second side splicing blocks 54 of the anti-jump rubber brick 51 are embedded in the splicing grooves 53 of the adjacent anti-jump rubber brick 51. Among them, the wooden board 3 is a flame-retardant wooden board, so that the wooden board 3 has a flame-retardant effect.

[0034] With the above structure, during live-fire shooting training, since the mobile bulletproof wall T-shaped corner includes a bulletproof steel plate 1 with a T-shaped structure, the outer surface of the bulletproof steel plate 1 is respectively provided with a steel structure frame 2, and the side of the steel structure frame 2 away from the bulletproof steel plate 1 is provided with a wooden board 3, and the side of the wooden board 3 away from the steel structure frame 2 is provided with an anti-bouncing rubber brick layer 5, the anti-bouncing rubber brick layer 5 includes a plurality of anti-bouncing rubber bricks 51 spliced ​​with each other, and the two adjacent edges of the anti-bouncing rubber brick 51 are respectively provided with a plurality of outwardly convex first side splicing blocks 52, and the adjacent first side splicing blocks 52 are spaced to form a splicing groove 53, and the other two adjacent edges of the anti-bouncing rubber brick 51 are respectively provided with a second side splicing block 54 matching the splicing groove 53, so that the anti-bouncing rubber brick 51 can be used for real-time shooting training. The second side splicing block 54 of the ricochet rubber brick 51 is embedded in the splicing groove 53 of the adjacent anti-ricochet rubber brick 51.
