Technical Field

[0001] The utility model belongs to the technical field of walls, and particularly relates to a bulletproof wall structure. Background Technique

[0002] At present, the tactical training rooms widely used in the national military and police systems mainly include reinforced concrete structures, brick-wood structures, frame structures, tire structures, etc. Among them, the walls of reinforced concrete structures and brick-wood structures are mainly built with reinforced concrete or bricks, which are relatively close to real buildings. However, such structures have high manufacturing costs and cannot be changed once built, and the walls themselves cannot effectively resist bullets; the walls of frame structures are mainly composed of steel frames and decorative panels. During training, personnel cannot touch such walls, nor can they be used for live ammunition tactical training.

[0003] At present, a single-layer buffer plate is used for buffering before bulletproof. During the shooting process, the bullet speed cannot be quickly reduced, and it cannot contract quickly. It cannot prevent the splashing of bullets, which will cause bullet ricochet, and the safety is not high. At the same time, it cannot be assembled according to the shooting range, and the use range is limited. For this reason, we propose a bulletproof wall structure. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a bulletproof wall structure to solve the problems mentioned in the above background technique, that is, a single-layer buffer plate is used for buffering before bulletproof.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figure 1 - Figure 2 , the present utility model provides a technical solution: a bullet - proof wall structure, including a bullet - proof steel plate 4. On both sides of the bullet - proof steel plate 4, multi - layer buffer assemblies 1 for preventing bullet ricochet are respectively arranged. The multi - layer buffer assemblies 1 are detachably connected to the bullet - proof steel plate 4 through the connection assembly 3, and the multi - layer buffer assemblies 1 are also horizontally spliced with the multi - layer buffer assemblies 1 in another group of bullet - proof walls through the clamping assembly 2;

[0025] The multi - layer buffer assembly 1 includes an outer bullet - proof panel 11 and an inner bullet - proof panel 15. The outer bullet - proof panel 11 and the inner bullet - proof panel 15 are connected by a plurality of inclined connecting bullet - proof panels 12. A closed buffer cavity 13 is formed between the outer bullet - proof panel 11, the inner bullet - proof panel 15 and the connecting bullet - proof panel 12. The buffer cavity 13 can be filled with corresponding buffer materials to further improve the anti - ricochet effect of the device. Specifically, the multi - layer buffer assembly 1 is formed by mixing and casting polyurethane, flame retardant and plasticizer, and has corresponding toughness and shrinkage. When a bullet penetrates the outer bullet - proof panel 11 and the inner bullet - proof panel 15, the outer bullet - proof panel 11 and the inner bullet - proof panel 15 can quickly reduce the bullet speed and quickly recover, avoiding bullet splashing. The buffer cavity 13 is one of a rhombus, a trapezoid, a regular polygon or a honeycomb shape.

[0026] First, connect the bulletproof steel plate 4 with two sets of multi-layer buffer components 1 through the connecting component 3. During actual use, the multi-layer buffer component 1 on one side can be used to connect with the bulletproof steel plate 4. When a bullet shoots, the bullet first penetrates the outer bulletproof panel 11. The outer bulletproof panel 11 conducts primary buffering on the impact force of the bullet. At the same time, the buffer material in the buffer cavity 13 can conduct secondary buffering on the impact force of the bullet. Meanwhile, the inner bulletproof panel 15 can conduct tertiary buffering on the impact force of the bullet, greatly improving the bulletproof effect. When the bullet penetrates the outer bulletproof panel 11 and the inner bulletproof panel 15, the bulletproof steel plate 4 provides bulletproof protection for the bullet. When the bullet impacts the bulletproof steel plate 4 and splashes or ricochets, the inner bulletproof panel 15 and the buffer material in the buffer cavity 13 can prevent the occurrence of bullet ricochet, greatly improving the use safety.

[0027] Furthermore, the outer bulletproof panel 11, the inner bulletproof panel 15, and the connecting bulletproof panel 12 are integrally cast and molded structures of polyurethane, flame retardant, and plasticizer, which is convenient for the production and processing of the multi-layer buffer component 1 and improves its retraction performance at the same time.

[0029] Please refer to Figure 1 - Figure 3 , the connecting component 3 includes an adapter steel plate 31. An adapter opening 34 is provided on the adapter steel plate 31. An adapter plate 33 is clamped in the adapter opening 34. The adapter plate 33 is connected to the bulletproof steel plate 4. Specifically, the adapter plate 33 and the bulletproof steel plate 4 are integrally formed structures, which can improve the overall strength of the bulletproof steel plate 4 and enable the quick connection between the adapter steel plate 31 and the bulletproof steel plate 4. An integrally formed skirt part is also provided on the adapter steel plate 31. The skirt part is connected to the connecting part 14 through a locking bolt 32. The connecting part 14 is arranged on one side of the connecting bulletproof panel 12, which can connect the adapter steel plate 31 with the multi-layer buffer components 1 on both sides.

[0030] First, place the adapter steel plate 31 on both sides of the bulletproof steel plate 4, and insert the adapter plate 33 into the adapter opening 34. Then, respectively fit the connecting parts on the two sets of multi-layer buffer components 1 to both sides of the adapter steel plate 31, and fix and connect the adapter steel plate 31 with the connecting part through the locking bolt 32, thereby fixing the two sets of multi-layer buffer components 1 on both sides of the bulletproof steel plate 4.

The first clamping portion 22 is provided on the outer bulletproof panel 11, and the second clamping portion 25 is provided on another group of outer bulletproof panels 11. The first clamping portion 22 and the second clamping portion 25 are respectively clamped in the first clamping groove 21 and the second clamping groove 24. The first clamping groove 21 and the second clamping groove 24 are respectively provided on both sides of the buckle 23, which can splice adjacent multi-layer buffer components 1, thereby expanding the use range of the device.

[0033] When it is necessary to expand the use area of the device, place adjacent devices flush with each other. Align the first clamping groove 21 and the second clamping groove 24 on the buckle 23 with the corresponding first clamping portion 22 and the second clamping portion 25 respectively, and push the buckle 23 downward, so that the first clamping portion 22 and the second clamping portion 25 are clamped in the first clamping groove 21 and the second clamping groove 24 to complete the quick connection of two groups of the device. Finally, according to the usage requirements, connect and assemble the corresponding number of the devices.

[0034] Furthermore, a T-shaped clamping block 26 is also provided on one side of the buckle 23. The T-shaped clamping block 26 is used to assist in positioning adjacent two groups of outer bulletproof panels 11. When the buckle 23 moves, the T-shaped clamping block 26 can fit with the inner wall of the adjacent outer bulletproof panel 11, which can further improve the firmness when connecting adjacent multi-group buffer components.
