For example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or connected through an intermediate medium, or the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.
[0030] Embodiment one:
[0031] As Figures 1-2As shown, the replaceable target plate bullet stopping device in the embodiment comprises a support frame 1, a base 2, a fixed target plate 3, a buffer target plate 4, a buffer spring 5, a first screw rod 6 and a first nut 7. The base 2 is arranged on both sides of the bottom of the support frame 1, and is used to support the support frame 1 and fix it on the ground.
[0032] The fixed target plate 3 is detachably arranged on the support frame 1. The fixed target plate 3 is connected with the support frame 1 through the second bolt 8 at each corner, and is locked through the second nut 9. In this way, the fixed target plate 3 can be quickly disassembled and replaced.
[0033] As shown, Figure 3 A plurality of first buffer pads 10 are arranged between the fixed target plate 3 and the support frame 1, and are used to reduce the vibration and noise after the bullet hits the target plate. The first buffer pad 10 is arranged at the connection between the second bolt 8 and the support frame 1, and is penetrated by the second bolt 8. The first buffer pad 10 can be made of flexible materials such as rubber, silicone and sponge.
[0034] The buffer target plate 4 is arranged obliquely on the front side of the fixed target plate 3. A group of first screw rods 6 are arranged on the upper and lower sides of the back of the buffer target plate 4. One end of the first screw rod 6 is fixedly connected with the back of the buffer target plate 4, and the threaded part of the other end penetrates through the adjusting hole 11 on the fixed target plate 3. The back of the fixed target plate 3 is connected with the threaded part of the first screw rod 6 through the first nut 7. The length of the group of first screw rods 6 on the upper side of the buffer target plate 4 is greater than the length of the group of first screw rods 6 on the lower side. In this way, the upper side of the buffer target plate 4 is inclined outward, and the buffer target plate 4 and the fixed target plate 3 form an inclination angle of 8°-15°, so that the bullet slows down after hitting the buffer target plate 4 and falls towards the ground.
[0035] The buffer spring 5 is sleeved on the outer side of the first screw rod 6 and abuts against the front of the fixed target plate 3 and the back of the buffer target plate 4 at both ends, so as to realize the buffering and deceleration of the bullet after hitting the buffer target plate 4.
[0036] The group of adjusting holes 11 on the upper side of the fixed target plate 3 is a round rectangle, and the group of adjusting holes 11 on the lower side of the fixed target plate 3 is a circle. When the upper buffer spring 5 is compressed after the bullet hits the buffer target plate 4, the corresponding first screw rod 6 on the upper side will swing to a certain amplitude, and the round rectangular adjusting hole 11 facilitates the swinging of the first screw rod 6.
[0037] The surface of the fixed target plate 3 is provided with a first fire-retardant layer 12, and the surface of the buffer target plate 4 is provided with a second fire-retardant layer 13. The first fire-retardant layer 12 and the second fire-retardant layer 13 can be made of fire-retardant cotton, fireproof cloth and other materials, which can reduce the impact force of the bullet and prevent high-temperature combustion caused by friction of the bullet.
[0038] By setting up structures such as the fixed target plate 3, the buffer target plate 4, and the buffer spring 5, the bullet can be blocked and slowed down. Furthermore, the buffer target plate 4 can slow down the bullet as it falls towards the ground under the action of the tilt angle, thus playing the role of blocking the bullet and recovering the bullet. The fixed target plate 3 and the buffer target plate 4 are easy to disassemble and replace, and their design life is no less than 40,000 bullet impacts. Without replacing the target plate, it can meet the needs of a basic unit for 3-5 years, and the economic benefits are very considerable.
[0039] Example 2:
[0040] like Figures 4-5 As shown, the ballistic blocking device with replaceable target plate in this embodiment is based on the first embodiment. A baffle 14 is provided on the upper side and the left and right sides of the support frame 1. The support frame 1 and the baffle 14 are provided with multiple threaded holes. The baffle 14 is detachably connected to the support frame 1 by a third bolt 15 passing through the threaded hole.
[0041] When an individual projectile impacts the edge of the fixed target plate 3 or the buffer target plate 4, it may glide and change direction. The baffle 14 can block the deflected projectile and prevent it from ricocheting.
[0042] Multiple second buffer pads 16 are provided between the baffle 14 and the support frame 1. The second buffer pads 16 can be set at the connection between the baffle 14 and the support frame 1 and are penetrated by the third bolt 15. The second buffer pads 16 can be made of flexible materials such as rubber, silicone, or sponge.
[0043] Example 3:
[0044] like Figure 6 As shown, the ballistic blocking device with replaceable target plate in this embodiment, based on embodiment two, has three vibration sensors 17 equidistantly spaced along the same straight line at the bottom edge of the fixed target plate 3. The vibration sensor 17 is a device that converts vibration signals into electrical signals. According to different working principles, it can be divided into piezoelectric vibration sensors, capacitive vibration sensors, eddy current vibration sensors, magnetoelectric vibration sensors, and resistance strain vibration sensors.
[0045] Taking a piezoelectric vibration sensor as an example, the three vibration sensors 17 in this embodiment can be Y1001, Y1001T-01A, Y1003 series piezoelectric vibration sensors, which are connected to the background reporting system through a double-headed M5 low-noise shielded cable; the reporting system is existing technology in this field and will not be described in detail here.
[0046] like Figure 7When the bullet hits the fixed target plate 3 or the buffer target plate 4, corresponding vibration and sound waves are generated, and the vibration waves (sound waves) are transmitted to each vibration sensor 17 respectively. Since the positions of the three vibration sensors 17 are different, the transmission distances of the vibration waves and the times when the vibration waves are received are also different, so that the bullet drop point distances (S1, S2, S3) from the three vibration sensors 17 can be calculated according to the formula S (the distance between the bullet drop point and the vibration sensor) = V (the transmission speed of the vibration wave≈340m / s)·T (the time when the vibration wave is transmitted to the vibration sensor) respectively, the bullet drop point can be at any point on the circular path with the vibration sensor 17 as the center, then the intersection point of the three circular paths is taken, the actual bullet drop point position after each shot can be determined, and the distribution statistics of the bullet drop area are realized, so that the shooting training effect is improved.
[0047] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of ordinary skilled persons in the art; when the combination of the technical solutions appears contradictory or unachievable, it shall be considered that the combination of the technical solutions does not exist, and is not within the protection scope required by the present application.
