Description

Technical Field

[0001] This invention relates to the field of police bulletproof shields, and more specifically, to a mounted bulletproof shield. Background Technology

[0002] Bulletproof shields are a common type of police equipment. They are made of high-strength polyethylene, aramid, UHMWPE, ceramic and other high-strength fiber materials and high-strength flame-retardant fiberglass using a special process. They can effectively block shrapnel, fragments and some projectiles, providing safety for personnel.

[0003] Patent CN221147357U discloses a bulletproof shield supported by a robotic arm, comprising: a bulletproof shield with a mounting rod on one side, the bulletproof shield being mounted to a handle via the mounting rod; a handle with a horizontal robotic arm on one side, the handle and the horizontal robotic arm being rotatably connected; a horizontal robotic arm with a vertical robotic arm mounted on one side, the horizontal robotic arm and the vertical robotic arm being rotatably connected; a vertical robotic arm with a fixed waist belt at the other end of the horizontal robotic arm, the vertical robotic arm and the fixed waist belt being rotatably connected; a fixed waist belt with a wearing mechanism mounted inside the fixed waist belt; and a wearing mechanism with its bottom mounted to the inside of the fixed waist belt via a waist strap.

[0004] The bulletproof shield described above can distribute the pressure of holding it with one hand to the waist and shoulders, improve the stability of walking while holding the bulletproof shield, offset the impact force of objects, extend the time that the bulletproof shield can be held with one hand, and improve combat efficiency. However, this bulletproof shield does not have the ability to be quickly disassembled, and it cannot free up both hands, making it impossible to carry out effective counter-shooting.

[0005] Therefore, a new solution is needed to address this problem. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a mountable bulletproof shield. The inward-sloping structure mechanically counteracts the forward-leaning moment, preventing the shield from tilting, swaying, or becoming fatigued during prolonged wear. It can also maintain a protective posture without the need for hand contact. Furthermore, it features a quick-release structure that allows the shield to be quickly separated from the police officer, instantly improving portability. The bulletproof shooting component can also provide the police officer with the conditions for rapid counterattack while ensuring their safety.

[0007] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a mountable bulletproof shield includes a shield body and bulletproof glass installed on the shield body. Several fixing plates are fixedly connected to the shield body. Buckles are detachably connected to the fixing plates. Both the buckles and the fixing plates are provided with slots. Adjacent buckles and fixing plates are respectively engaged by two slots in a cross-shaped interlocking manner. A bracket is fixedly connected to the shield body. A support block is fixedly connected to the bracket. The support block is made of a material with elastic deformation capabilities, such as sponge or silicone, to ensure that the shield does not cause strong discomfort during long-term use. When the shield body is in use, the upper part of the shield body is tilted towards the human body, that is, the shield body will tilt inward by 6-12 degrees. A through slot is opened on the shield body. The shield body is provided with a bulletproof shooting component for mobile shooting.

[0008] According to the design, the bulletproof shield is designed with an inward tilting structure and is equipped with buckles and fixing plates. When the buckles are fixed to the front of both sides of the external belt using existing technology, the shield body can be quickly hung on the external belt through the fixing plates. Then, the support block will abut against the hip of the human body, providing forward support force, which can mechanically counteract the forward tilting torque, so that the shield does not tilt down, does not wobble, and has low fatigue during long-term wear.

[0009] The invention is further configured such that: the bulletproof shooting assembly includes a positioning block slidably connected in a through groove, a bulletproof plate fixedly connected to the positioning block, a bracket fixedly connected to the shield body, a sliding block slidably connected to the bracket, and a handle rotatably connected to the sliding block; the inner walls of the bracket are serrated on both sides; a bidirectional spring telescopic rod is fixedly connected inside the sliding block; a limiting block is fixedly connected to both telescopic ends of the bidirectional spring telescopic rod; the limiting block can be placed into the toothed groove of the serrated part of the bracket; two connecting rods are connected between the sliding block and the positioning block; and a shooting hole is provided on the bulletproof plate.

[0010] According to the plan, a bulletproof plate with firing ports is installed for defensive and counter-firing purposes. It is also equipped with a hand rest to further improve the comfort of holding the gun and the accuracy of aiming. At the same time, the hand rest and bulletproof plate adopt a multi-level adjustable structure, which can adjust the distance according to the police officer's height and gun-holding habits to improve the comfort of holding the gun and the accuracy of shooting.

[0011] The present invention is further configured such that: the upper end of the connecting rod is serrated, a bidirectional spring telescopic rod II is fixedly connected inside the positioning block, and a limit block II is fixedly connected to both telescopic ends of the bidirectional spring telescopic rod II, and the retractable limit block II can be placed into the tooth groove of the serrated part of the connecting rod.

[0012] According to the scheme, by opening a serrated groove on the connecting rod and cooperating with the limiting block 2, the relative distance between the firing port and the hand rest can be adjusted to adapt to the holding posture of different firearms.

[0013] The invention is further configured such that: a hook is rotatably connected to the fixed plate, and a torsion spring is provided on the rotating shaft of the hook. The two ends of the torsion spring are respectively fixedly connected to the hook and the fixed plate. When the buckle is in the installation state, the hook restricts the buckle.

[0014] According to the solution, when the buckle is installed on the fixed plate, the buckle can be automatically locked by the hook to prevent the shield body from falling off the external belt when moving.

[0015] The present invention is further configured such that: the sliding block is fixedly connected to a plurality of limiting plates on the upper side of the support.

[0016] According to this scheme, the rotation angle of the stock can be limited to prevent excessive rotation when the stock is in a gun-holding position.

[0017] The invention is further configured such that a protective ring is fixedly connected to the firing port.

[0018] According to this plan, the gun barrel can be protected to prevent barrel wear.

[0019] In summary, the present invention has the following beneficial effects: 1. The inward tilting structure can mechanically counteract the forward tilting torque, so that the shield does not tilt down or sway, and the fatigue is reduced when wearing it for a long time. It also frees up the hands, so that while holding the shield and gun for vigilance, the hands can still be freed up to perform other tactical actions. 2. The support frame 5 is adjustable in length to suit different body types; 3. The quick-release structure allows the shield to be quickly separated from the police officer, instantly improving portability. 4. Multi-level adjustment and strong adaptability: The hand rest and bulletproof plate adopt a multi-level adjustment structure, which can adjust the distance according to the police officer's height and gun-holding habits, adapt to different usage scenarios, and improve the comfort of holding the gun and shooting accuracy; 5. The firing port position can be quickly adjusted by pressing with the thumb and forefinger. It can be operated quickly with one hand without delaying holding the gun, aiming, and firing. It conforms to the logic of actual combat operation and can quickly raise and lower the firing port during continuous firing to expand the firing range. 6. When the firing port is in its lowest position, it is completely covered by the shield. When firing, the firing port is blocked by the firearm, providing full protection for the police officers without any gaps in protection. 7. Equipped with a rubber protective ring to protect the gun barrel and prevent barrel wear; 8. The overall structure is simple, with no complex transmission structure, low failure rate and easy maintenance. Attached Figure Description

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] A type of mounted bulletproof shield, such as Figures 1-8 As shown, the shield includes a shield body 1 and a bulletproof glass 2 mounted on the shield body 1. Several fixing plates 3 are fixedly connected to the shield body 1, and buckles 4 are detachably connected to the fixing plates 3. A bracket 5 is fixedly connected to the shield body 1 (the bracket 5 can be extended and adjusted in length to suit different body types; the specific extension and retraction methods and how to fix it after extension are existing technologies and will not be described in detail). A support block 6 is fixedly connected to the bracket 5. When the shield body 1 is in use, the upper part of the shield body 1 is tilted towards the human body. A through groove 7 is provided on the shield body 1 (the through groove 7 is positioned slightly to the right of the center when viewed from the protective surface of the shield body 1, which facilitates right-handed shooting). The shield body 1 is equipped with a bulletproof shooting component for mobile shooting. A hook 19 is rotatably connected to the fixing plate 3. When the buckle 4 is in the installation state, the hook 19 restricts the buckle 4.

[0024] like Figures 1-8As shown, when in use, the buckle 4 is first fixed to the external tactical belt using existing technology. Then, the shield body 1 can be lifted, and the slot on the fixing plate 3 is inserted into the slot of the adjacent buckle 4 to form a cross-lock. During this process, the buckle 4 will contact the inclined surface of the hook 19 and drive the hook 19 to rotate. When fully engaged, the hook 19 will reset and rotate due to gravity. At this time, the bent part of the hook 19 will be under the buckle 4 to restrict the buckle 4. At the same time, the support block 6 will abut against the hip of the human body to provide forward support force. In this way, the forward tilting torque can be mechanically counteracted, so that the shield body 1 does not tilt down, does not sway, is not fatigued after long-term wear, and can move freely and be used for counter-firing through the ballistic shooting components.

[0025] like Figures 2-6 As shown, the bulletproof shooting assembly includes a positioning block 8 slidably connected in the through groove 7, a bulletproof plate 9 fixedly connected to the positioning block 8, a bracket 10 fixedly connected to the shield body 1, a sliding block 11 slidably connected to the bracket 10, and a handle 12 rotatably connected to the sliding block 11 (which hangs down naturally in the absence of external force). The inner walls of the bracket 10 are serrated on both sides. A bidirectional spring telescopic rod 13 is fixedly connected in the sliding block 11. Limiting blocks 14 are fixedly connected to both telescopic ends of the bidirectional spring telescopic rod 13. The limiting blocks 14 can be inserted into the toothed grooves of the serrated part of the bracket 10. Two connecting rods 15 are connected between the sliding block 11 and the positioning block 8. A shooting hole 16 is opened on the bulletproof plate 9.

[0026] like Figures 2-6As shown, when adjusting the position of the firing port 16, the two limiting blocks 14 can be moved closer together by the thumb and forefinger (the two-way spring telescopic rod 13 is in the retracted state). When the two limiting blocks 14 disengage from the toothed grooves of the bracket 10, the positioning block 8 can slide down or up simultaneously. At this time, the positioning block 8 will drive the bulletproof plate 9 to move up and down through the connecting rod 15 and the sliding block 11. At this time, the firing port 16 will also move up and down simultaneously. When the firing port 16 moves to the appropriate position, the thumb and forefinger can be released. At this time, the two-way spring telescopic rod 13 will reset, driving the two limiting blocks 14 to move away from each other and into other toothed grooves of the bracket 10. In this way, the position of the firing port 16 can be adjusted according to the needs of the police officer; when counter-firing is required... When firing, first pass the barrel through the firing port 16, then use your left hand to support the handrail 12, and then let the handrail 12 support the firearm (e.g., the support of a pistol is the magazine). At this time, you can quickly counter-fire (because this is a counter-fire, there is no need to aim, just rely on muscle memory to quickly draw the gun and fire). When counter-firing, you can also use your left thumb and forefinger to control the two limit blocks 14 to move closer to each other, and quickly adjust the position of the firing port 16 temporarily. When the shield body 1 is in a fully protected state and the firing port 16 is not needed, you can control the positioning block 8 to slide to the bottom of the bracket 10. At this time, the firing port 16 will be blocked by the shield body 1 (the bulletproof plate 9 will still completely block the through slot 7), and provide full shielding protection to ensure that there is no gap in the protection.

[0027] like Figure 2 , Figure 4 , Figure 6 As shown, the upper end of the connecting rod 15 is serrated. A two-way spring telescopic rod 17 is fixedly connected inside the positioning block 8. Limiting blocks 18 are fixedly connected to both telescopic ends of the two-way spring telescopic rod 17. The limiting blocks 18 can be placed into the toothed grooves of the serrated part of the connecting rod 15. When it is necessary to adjust the relative position of the firing port 16 and the hand rest 12, the two limiting blocks 18 can be pressed and controlled to move closer to each other according to the needs of the selected firearm. When the two limiting blocks 18 are dislodged from the toothed grooves on the two connecting rods 15, the sliding block 11 can be controlled to slide and drive the bulletproof plate 9 to slide. At this time, the firing port 16 will move away from or closer to the hand rest 12. When the firing port 16 reaches the desired position, the thumb and forefinger can be released. At this time, the two-way spring telescopic rod 17 will be reset, causing the two limiting blocks 18 to move away from each other and be placed into other toothed grooves of the connecting rod 15, thereby changing the distance between the firing port 16 and the hand rest 12.

[0028] like Figures 4-5 As shown, the sliding block 11 is fixedly connected to several limiting plates 20 on the upper side of the handle 12. When the handle 12 rotates from its natural vertical state by 90 degrees to 80 degrees, the limiting plates 20 will block the handle 12 to prevent it from continuing to rotate and overturn.

[0029] like Figure 1 , Figure 3 As shown, a protective ring 21 is fixedly connected to the firing port 16, which can protect the barrel and reduce barrel wear.

[0030] Working principle: In use, first, fastener 4 is fixed to the external tactical belt using existing technology. Then, the shield body 1 is raised, and the slot on the fixing plate 3 is inserted into the slot of the adjacent fastener 4 for cross-locking. During this process, fastener 4 contacts the inclined surface of hook 19 and drives hook 19 to rotate (at this time, the torsion spring deforms). When fully engaged, hook 19 will rotate and return to its original position due to the torsion spring's reset. At this time, the bent part of hook 19 will be under the fastener 4, restricting it. Simultaneously, support block 6 will abut against the hip, providing forward support force. This mechanically counteracts the forward tilting torque, preventing the shield from tilting, swaying, and causing fatigue even after prolonged wear. The overall weight of the police bulletproof shield is ≤8kg (weight varies depending on the bulletproof material; for example, 8mm...). The shield body is constructed using UHMWPE + 1.5mm ceramic + 0.5mm resin, while the viewing window is made of 4.5mm ceramic + 0.2mm graphene composite film + 10mm high-impact PC. The shield's ballistic protection level easily surpasses GA3. The weight is calculated as follows: Shield body area: 0.5*0.9 - 0.34*0.22 = 0.3752 square meters; UHMWPE weight: 0.3752 × 0.008 × 970 ≈ 2.91 kg; Ceramic (bottom 200mm uncovered): 0.275*0.0015*3900 ≈ 1.61 kg; Resin weight: approximately 0.18 kg; Viewing window area: 0.34*0.22 = 0.0748 square meters; Viewing window ceramic: 0.0748 × 0.0045 × 3900 ≈ 1.31 kg; Viewing window PC: 0.0748 × 0.010 × 1200 ≈ 0.90 kg, graphene 0.02 kg, structural components approximately 0.6 kg. Total weight is 2.91 + 1.61 + 0.18 + 1.31 + 0.9 + 0.02 + 0.6 ≈ 7.53 kg. (For GA2 ballistic protection, the total weight is approximately 6.14 kg.) Allows for free movement and allows for counter-fire through the ballistic protection firing components.

[0031] When counter-firing is required, the two limiting blocks 14 can be moved closer together by the left thumb and forefinger to adjust the position of the hand rest 12. The hand rest 12 can then be lifted up by the palm of the hand, at which point the firing port 16 will be exposed. Then, simply pass the barrel through the firing port 16 and place the gun on the hand rest 12. At this point, a rapid counter-firing can be carried out. In addition, during the counterattack, the two limiting blocks 14 can be moved closer together by the left thumb and forefinger to quickly adjust the position of the firing port 16.

[0032] When it is necessary to remove the shield body 1, the hook 19 can be rotated to disengage from the underside of the buckle 4, thus removing the restriction on the buckle 4. Then, the shield body 1 can be lifted to remove it. Alternatively, a quick-release tactical belt can be used (existing technology allows for one-click disengagement and quick removal of the belt). The buckle 4 can then be fixed to the quick-release tactical belt. At this point, the quick-release tactical belt can be removed directly from the body, and the shield body 1 will fall off.

[0033] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
