[0003] However, existing range ammunition receiving wall structures are difficult to repair when damaged, and their simple structure results in poor bullet cushioning capabilities. Utility Model Content
[0004] The purpose of this application is to at least address the problems of inconvenient repair of existing range ammunition receiving wall structures when damaged, and the poor buffering capacity of existing range ammunition receiving walls for bullets. This purpose is achieved through the following means:
[0005] This application discloses a bullet receiving device, comprising: a deflection layer, a buffer layer, and a blocking layer. The deflection layer is used to deflect the bullet when it passes through it; the buffer layer has multiple rubber units, which are used to deform when the bullet passes through them and can absorb the bullet's kinetic energy; the blocking layer is used to block the bullet's movement when it passes through it; wherein the deflection layer, the buffer layer, and the blocking layer are sequentially and detachably connected.
[0006] The bullet-collecting device of this application deflects the bullet through a deflection layer, thereby increasing the energy consumption of the bullet during its motion. The rubber unit deforms when the bullet passes through it, absorbing the bullet's kinetic energy. The blocking layer further increases the bullet's energy consumption, thus blocking the bullet. Therefore, the bullet is buffered in multiple stages through the deflection layer, buffer layer, and blocking layer, thereby increasing the bullet's blocking capability. Furthermore, the synergistic effect of the deflection layer and buffer layer increases the difficulty for the bullet to pass through the rubber unit, further increasing the bullet's blocking capability. By making the deflection layer, buffer layer, and blocking layer detachably connected, when one or more of these layers are damaged, the damaged part can be disassembled and replaced, reducing maintenance difficulty. Moreover, because the deflection layer, buffer layer, and blocking layer are detachably connected, the bullet-collecting device of this application embodiment can be transported in parts, thereby reducing the transportation difficulty of the bullet-collecting device of this application embodiment.

The second rubber group includes a plurality of rubber units. The plurality of rubber units are arranged sequentially along the width direction of the buffer layer.
[0008] In some embodiments, along the thickness direction of the buffer layer, two adjacent rubber units in each second rubber group overlap each other, and the buffer layer includes a plurality of first rubber groups, which are stacked sequentially along the thickness direction of the buffer layer.
[0009] In some embodiments, the rubber unit is a tire rubber component.
[0010] In some embodiments, the deflection layer includes a polyurethane matrix and a plurality of metal particles disposed within the polyurethane matrix to impede the bullet upon contact with it, thereby enabling the bullet to deflect.

[0038] A bullet collection wall is an important structure in a shooting range used to absorb and collect bullets generated during firing, ensuring personnel safety, protecting facilities and equipment, and maintaining the environment.
[0039] However, existing range ammunition receiving walls are difficult to repair when damaged, and their ability to cushion bullets is poor.
[0040] In order to at least solve the problems of the inconvenience of repairing the existing range ammunition receiving wall structure when it is damaged, and the poor buffering capacity of the existing range ammunition receiving wall for bullets, the embodiments of this application propose an ammunition receiving device 100, which can reduce the difficulty of repair and can increase the buffering capacity for bullets through multi-stage buffering.
[0041] The receiving device 100 of this application embodiment is described below with reference to the accompanying drawings.
[0042] Figure 1 This is a schematic diagram of the ammunition receiving device according to an embodiment of this application; Figure 2 A schematic diagram of the deflection layer in an embodiment of this application; Figure 3 for Figure 2 A half-section schematic diagram of the deflection layer in the buffer layer, wherein the sectional view is a sectional view taken by planes through the thickness direction and the length direction of the buffer layer; Figure 4 This is a half-sectional schematic diagram of the deflection layer according to another embodiment of this application, wherein the sectional view is a sectional view taken by planes through the thickness direction and the length direction of the buffer layer; Figure 5 This is a cross-sectional view of the buffer layer according to an embodiment of this application, wherein the cross-sectional view is a cross-sectional view taken by planes through the thickness direction and the length direction of the buffer layer; Figure 6 for Figure 5 Sectional view at point A in the middle; Figure 7 This is a schematic diagram of a buffer layer according to another embodiment of the present application, wherein the cross-sectional view is a cross-sectional view taken by a plane through the thickness direction and the length direction of the buffer layer; Figure 8 for Figure 7 Sectional view at point B.
[0043] like Figure 1 As shown, this application proposes a bullet receiving device 100, comprising: a deflection layer 10, a buffer layer 20, and a blocking layer 30. The deflection layer 10 is used to deflect the bullet when it passes through it; the buffer layer 20 has a plurality of rubber units 2111, which are used to deform when the bullet passes through them and can absorb the kinetic energy of the bullet; the blocking layer 30 is used to block the movement of the bullet when it passes through them; wherein, the deflection layer 10, the buffer layer 20, and the blocking layer 30 are detachably connected in sequence.
[0044] In this embodiment of the bullet receiving device 100, when the bullet is absorbed, the bullet sequentially passes through the deflection layer 10, the buffer layer 20, and the blocking layer 30. As some examples, the direction of the bullet's entry is as follows: Figure 1As indicated by the arrow at point e, when the bullet passes through the deflection layer 10, it is deflected under the action of the deflection layer 10, causing the bullet to move along a curved or broken trajectory within the bullet collection device 100 of this embodiment. This increases the energy consumption of the bullet within the bullet collection device 100, thereby improving the bullet-trapping effect of the bullet collection device 100 in this embodiment. Furthermore, the deflection under the action of the deflection layer 10 changes the bullet's projectile angle, causing the bullet body to rub against the bullet collection device 100 of this embodiment. This further increases the energy consumption of the bullet within the bullet collection device 100, thereby further improving the bullet-trapping effect of the bullet collection device 100 in this embodiment.
[0045] When the bullet passes through the buffer layer 20, it comes into contact with the rubber unit 2111 of the buffer layer 20. The rubber unit 2111 deforms when the bullet passes through it and absorbs the bullet's kinetic energy. This further increases the energy consumption of the bullet in the bullet-collecting device 100 of this embodiment, thereby further improving the bullet-trapping effect of the bullet-collecting device 100 of this application embodiment. Moreover, since the bullet deflects when it passes through the deflection layer 10, the resistance of the bullet passing through the rubber unit 2111 is further increased. Under the synergistic effect of the deflection layer 10 and the buffer layer 20, the energy consumption of the bullet in the bullet-collecting device 100 of this embodiment is further increased, thereby further improving the bullet-trapping effect of the bullet-collecting device 100 of this application embodiment.
[0046] As an example, in some shooting scenarios, using .22LR bullets as the firing bullets, through the synergistic effect of the deflection layer 10 and the buffer layer 20, the rubber unit 2111 can consume 30% to 40% of the bullet's kinetic energy, thereby greatly increasing the bullet's stopping effect.
[0047] When the bullet passes through the stabilizing layer 30, the bullet's kinetic energy is relatively low. The stabilizing layer further consumes the bullet's energy, thus trapping the bullet.
[0048] As an example, in some shooting scenarios, when using .22LR bullets as the firing bullets, and the bullet's initial velocity is 320 m / s, the bullet's retention rate can reach 99.8% when passing through the bullet collection device 100 implemented in this application.
[0049] By making the deflection layer 10, buffer layer 20 and blocking layer 30 detachably connected, when one or more of the deflection layer 10, buffer layer 20 and blocking layer 30 are damaged, the damaged part can be disassembled and replaced, thereby reducing the difficulty of maintenance.
[0050] Furthermore, since the deflection layer 10, the buffer layer 20, and the blocking layer 30 are detachably connected, the ammunition receiving device 100 of this application embodiment can be disassembled during transportation, so that the deflection layer 10, the buffer layer 20, and the blocking layer 30 can be separated from each other and transported. In other words, the ammunition receiving device 100 of this application embodiment can be transported in parts, thereby reducing the transportation difficulty of the ammunition receiving device 100 of this application embodiment.
[0051] The bullet receiving device 100 of this application embodiment can deflect the bullet through the deflection layer 10, thereby increasing the energy consumption of the bullet during its movement. The rubber unit 2111 deforms when penetrated by the bullet, absorbing the bullet's kinetic energy. The blocking layer 30 further increases the bullet's energy consumption, thus blocking the bullet. Therefore, the deflection layer 10, buffer layer 20, and blocking layer 30 provide multi-stage buffering for the bullet, thereby increasing its blocking capability. Furthermore, the synergistic effect of the deflection layer 10 and buffer layer 20 increases the difficulty for the bullet to penetrate the rubber unit 2111, further enhancing its blocking capability. By making the deflection layer 10, buffer layer 20, and blocking layer 30 detachably connected, when one or more of these layers are damaged, the damaged part can be disassembled and replaced, reducing maintenance difficulty. Furthermore, since the deflection layer 10, the buffer layer 20, and the blocking layer 30 are detachably connected, the ammunition receiving device 100 of this application embodiment can be transported in parts, thereby reducing the transportation difficulty of the ammunition receiving device 100 of this application embodiment.
[0052] Combination Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in some embodiments, the buffer layer 20 includes a first rubber group 21 and a buffer substrate 22. The first rubber group 21 is disposed within the buffer substrate 22. The first rubber group 21 includes a plurality of second rubber groups 211. The plurality of second rubber groups 211 are arranged sequentially along the length direction b of the buffer layer. The second rubber group 211 includes a plurality of rubber units 2111. The plurality of rubber units 2111 are arranged sequentially along the width direction c of the buffer layer.
[0053] The buffer matrix 22 is a matrix formed of a material with a buffering effect; as an example, the buffer matrix 22 is a polyurethane matrix. Polyurethane has a strong energy absorption capacity and a strong buffering effect against bullets. Polyurethane has good resilience, which can increase the service life of the buffer layer 20. Polyurethane has good sound absorption capacity, which can reduce the noise generated by the buffer layer 20. Polyurethane has a low density, which can reduce the weight of the buffer layer 20, making the buffer layer 20 easy to transport.
[0054] By providing the rubber unit 2111 on the buffer substrate 22, the buffer substrate 22 can prevent the rubber unit 2111 from deforming, thereby further increasing the bullet-receiving device 100 of this application embodiment can resist bullets.
[0055] By making the first rubber group 21 include multiple second rubber groups 211, which are arranged sequentially along the length direction b of the buffer layer, and each second rubber group 211 includes multiple rubber units 2111, which are arranged sequentially along the width direction c of the buffer layer, the rubber units 2111 can be densely arranged along the length direction b and the width direction c of the buffer layer. This ensures that when a bullet enters the buffer layer 20 from different positions, the rubber units 2111 have a high probability of contacting the bullet, thereby enabling the buffer substrate 22 to effectively buffer the bullet.
[0056] In some optional embodiments, during the production of the buffer layer 20, the rubber units 2111 are suspended and fixed, and the molding material of the buffer substrate 22 is poured in to form the buffer substrate 22, thereby forming the buffer layer 20. Therefore, during the production process of the buffer layer 20, the suspension density, shape, hardness of the rubber units 2111, and the ratio and thickness of the buffer substrate 22 material can be flexibly selected according to actual conditions, thus giving the production process of the rubber units 2111 high flexibility.
[0057] Combination Figure 7 and Figure 8 As shown, in some optional embodiments, the edges of two adjacent rubber units 2111 abut against each other to achieve close packing.
[0058] Combination Figure 5 and Figure 6 As shown, in some embodiments, along the thickness direction a of the buffer layer, two adjacent rubber units 2111 in each second rubber group 211 overlap each other, and the buffer layer 20 includes a plurality of first rubber groups 21, which are stacked sequentially along the thickness direction a of the buffer layer.
[0059] Along the thickness direction a of the buffer layer, two adjacent rubber units 2111 in each second rubber group 211 overlap each other, thereby further increasing the blocking effect on the bullet when it passes through the overlapping part of the rubber units 2111, thereby further increasing the blocking effect of the bullet receiving device 100 of this application embodiment on the bullet.
[0060] Multiple first rubber groups 21 are stacked sequentially along the thickness direction a of the buffer layer, so that when the bullet passes through the buffer layer 20, it needs to pass through the rubber units 2111 of the multiple first rubber groups 21, which can further increase the blocking effect on the bullet, thereby further increasing the blocking effect of the bullet receiving device 100 of this application embodiment on the bullet.
[0061] Furthermore, the rubber unit 2111 in one second rubber group 211 overlaps with the adjacent rubber unit 2111 in another second rubber group 211, thereby increasing the overlapping area of the rubber units 2111 in different second rubber groups 211, which in turn can further increase the bullet-retarding effect of the bullet receiving device 100 in this application embodiment.
[0062] Optionally, multiple first rubber groups 21 are stacked in a staggered manner along the thickness direction a of the buffer layer, thereby reducing the dead angles of the buffer layer 20 and increasing the probability of the rubber unit 2111 contacting the bullet, so that the buffer substrate 22 can effectively buffer the bullet.
[0063] In some embodiments, the rubber unit 2111 is a tire rubber component.
[0064] By using tire rubber to manufacture rubber units 2111, waste rubber can be utilized, thereby increasing the environmental friendliness of tire rubber processing and significantly reducing the production cost of rubber units 2111. For example, by using tire rubber to manufacture rubber units, the cost of some types of buffer layers 20 can be reduced by at least 80%, thus significantly reducing production costs.
[0065] Combination Figure 3 and Figure 4 As shown, in some embodiments, the deflection layer 10 includes a polyurethane matrix 11 and a plurality of metal particles 12 disposed within the polyurethane matrix 11 to impede the bullet when in contact with it, thereby enabling the bullet to deflect.
[0066] As an example, the metal particles 12 can be steel particles, tungsten particles, etc.
[0067] When the bullet moves in the deflection layer 10 and comes into contact with the metal particles 12, the metal particles 12 exert resistance on the bullet as the bullet moves, thereby hindering the bullet and causing it to deflect. This deflects the bullet's trajectory and changes the bullet's head angle, thus achieving the deflection of the bullet and further improving the bullet-receiving device 100 of this application embodiment's blocking effect on the bullet.
[0068] Polyurethane has strong energy absorption capacity and a strong cushioning effect against bullets. It also has good resilience, increasing the service life of the deflection layer 10. Furthermore, polyurethane has good sound absorption capabilities, reducing the noise generated by the deflection layer 10. Its low density reduces the weight of the deflection layer 10, making it easier to transport.
[0069] like Figure 3 and Figure 4 As shown, in some embodiments, the deflection layer 10 has a deflection surface 13 facing away from the buffer layer 20, and the deflection surface 13 is set at an angle to the vertical direction d, the angle being 15° to 45°.
[0070] The deflection surface 13 is set at an angle to the vertical direction d, such as... Figure 4 As shown, when the deflection layer 10 is suspended vertically, both the length direction b and the width direction c of the buffer layer intersect the deflection surface 13; combined with Figure 2 and Figure 3 As shown, when the deflection layer 10 is suspended vertically, the length direction b and the width direction c of the buffer layer are both parallel to the deflection surface 13, and the deflection layer 10 is suspended in a way that is relatively inclined to the vertical direction, so that the deflection surface 13 is at an angle to the vertical direction d.
[0071] When a bullet enters the deflection layer 10, it enters the deflection layer 10 through the deflection surface 13. By setting the deflection surface 13 at an angle to the vertical direction d, with the angle ranging from 15° to 45°, the probability of the bullet tumbling after entering the deflection layer 10 can be increased, thereby further improving the bullet-receiving device 100 of this application embodiment's blocking effect on the bullet.
[0072] Taking the 5.56mm NATO round (23mm warhead length, 940m / s muzzle velocity) as an example, when the angle between the deflection surface 13 and the vertical direction d is 15°, the probability of tumbling is 12%-18%, and when the angle between the deflection surface 13 and the vertical direction d is 45°, the probability of tumbling can reach 60%.
[0073] like Figure 3 and Figure 4 As shown, in some embodiments, the deflection surface 13 is provided with flame-retardant fabric 14.
[0074] The flame-retardant fabric 14 can prevent sparks from being generated when it comes into contact with the bullet, thereby improving the safety of the bullet receiving device 100 in this application embodiment.
[0075] In some alternative embodiments, the oxygen index of the flame-retardant fabric 14 is greater than or equal to 32.
[0076] The oxygen index is an important indicator for measuring the combustion performance of materials, mainly used to evaluate the flame retardancy of materials under specific conditions. The oxygen index reflects the minimum oxygen concentration required for a material to sustain combustion and is a quantitative characterization of the material's flame retardant properties.
[0077] When the oxygen index is greater than or equal to 32, the flame-retardant fabric 14 is difficult to burn and decomposes but does not burn at high temperatures, thereby further improving the safety of the bomb collection device 100 in this application embodiment.
[0078] As some examples, flame-retardant fabric 14 with an oxygen index greater than or equal to 32 can be polyimide, glass fiber, etc.
[0079] like Figure 2 As shown, in some embodiments, steel wire cords 40 are connected to both the upper and lower sides of the deflection layer 10. The angle between the steel wire cord 40 on the upper side of the deflection layer 10 and the vertical direction d is 15°, and the angle between the steel wire cord 40 on the lower side of the deflection layer 10 and the vertical direction d is 30°.
[0080] By having the steel wire cord 40 located on the upper side of the deflection layer 10 at an angle of 15° to the vertical direction d, and the steel wire cord 40 located on the lower side of the deflection layer 10 at an angle of 30° to the vertical direction d, the deflection layer 10 can be kept at a suitable angle, thereby increasing the probability of the bullet tumbling after entering the deflection layer 10, and further improving the bullet-receiving device 100 of this application embodiment for blocking the bullet.
[0081] In some embodiments, the receiver 100 further includes a frame, to which the deflection layer 10, the buffer layer 20, and the blocking layer 30 are detachably mounted.
[0082] By mounting the deflection layer 10, buffer layer 20, and retardation layer 30 onto the frame, the installation stability of the deflection layer 10, buffer layer 20, and retardation layer 30 can be increased.
[0083] As examples, the deflection layer 10, buffer layer 20, retardation layer 30 and frame are all bolted together, thereby enabling a detachable connection between the deflection layer 10, buffer layer 20, retardation layer 30 and frame, and facilitating disassembly between the deflection layer 10, buffer layer 20, retardation layer 30 and frame.
[0084] In some embodiments, the barrier layer 30 is a polyurethane layer.
[0085] Polyurethane has strong energy absorption capacity and a strong cushioning effect against bullets. It also has good resilience, increasing the service life of the damping layer 30. Furthermore, polyurethane has good sound absorption capabilities, reducing the noise generated by the damping layer 30. Its low density reduces the weight of the damping layer 30, making it easier to transport.
[0086] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
