Description

Technical Field

[0001] This utility model relates to the field of rigid shield technology, and in particular to a folding rigid shield with a bulletproof viewing window. Background Technology

[0002] Riot shields are commonly used defensive equipment by modern riot police and military forces. Their construction includes a shield plate and a support plate. The shield plate is typically convex, rounded, or rectangular with an arc surface. The support plate is fixed to the back of the shield plate via connectors. The support plate has straps and a handle. Riot shields are usually made of lightweight materials such as polycarbonate, PC, and fiberglass. Riot shields used by riot police are generally used to deal with low-level conflicts such as mass disturbances, effectively blocking impacts and thrusts from objects such as bricks, stones, sticks, and glass bottles. Riot shields used by special police forces generally also have bulletproof, shockwave, and glare protection capabilities.

[0003] Existing rigid shields are bulky and poorly portable, making them cumbersome to move, and concealment is also a requirement for shields. Utility Model Content

[0004] In order to overcome the shortcomings of existing rigid shields in terms of portability and concealment, the technical problem of this utility model is to provide a folding rigid shield with a bulletproof viewing window.

[0005] Technical Solution: A folding rigid shield with a bulletproof viewing window, comprising a front shield plate, a hinge frame, an energy-absorbing plate, side shield plates, pull rods, four corner levers, a telescopic spring, a guide rail, a slider, webbing, and a handle. The three front shield plates are arranged longitudinally, with the central front shield plate positioned further forward. A hinge frame symmetrically connects each pair of front shield plates. Each front shield plate contains an energy-absorbing plate. Side shield plates are rotatably connected to both sides of each of the three front shield plates. A pull rod is symmetrically positioned on the upper part of the central front shield plate, and pull rods are also provided on the rear sides of the upper and lower side shield plates. Four corner levers are fixed to the bottom of each of the four sides. The upper and lower side shields and the central front shield all have slots on their upper parts. Four corner levers are fixed to the bottom of each of the four levers, and the four corner levers are slidably connected to the slots of the corresponding front or side shields. A telescopic spring is fitted on the lower outer side of the lever and is connected between the lever and the corresponding front or side shield. The lower front of the central front shield has symmetrical guide rails, and two guide rails are slidably connected to sliders. A webbing is connected between the two sliders. A handle is rotatably connected to the upper front of the central front shield.

[0006] In addition, it is particularly preferred that it also includes bulletproof windows, with bulletproof windows provided on the upper front shield plate and the two side shield plates.

[0007] Furthermore, it is particularly preferred that the device also includes a limiting rod, with the lower part of the two upper side windows that are close to each other being fixedly connected to the limiting rod, and the upper part of the two lower side windows that are close to each other being fixedly connected to the limiting rod.

[0008] Furthermore, it is particularly preferred that the device also includes storage bags, with two storage bags provided on each side of the two lower side windows that are close to each other.

[0009] Furthermore, it is particularly preferred that the device also includes light strips, which are fixedly attached to the rear of the upper and lower frontal shields on the sides that are close to each other.

[0010] Furthermore, it is particularly preferred that the energy-absorbing panel is made of ultra-high molecular weight polyethylene.

[0011] Beneficial effects: Through the articulated frame and multi-modal design, the shield can achieve 180-degree folding of the three-layer front shield plate and 270-degree rotational folding of the side shield plate. After folding, the volume is reduced by more than 60%, which is convenient for transportation and carrying, and is especially suitable for rapid deployment and operation in narrow spaces.

[0021] A folding rigid shield with bulletproof viewing windows, such as Figures 1-7 As shown, the system includes a front shield 1, a hinge frame 5, an energy-absorbing plate 2, a side shield 4, a pull rod 30, four corner levers 31, a telescopic spring 32, a guide rail 8, a slider 6, a webbing 7, and a handle 9. The three front shields 1 are arranged longitudinally, with the central front shield 1 positioned further forward. A hinge frame 5 is symmetrically and rotatably connected between every two front shields 1. An energy-absorbing plate 2 is fitted inside each front shield 1. Side shields 4 are rotatably connected to both sides of each of the three front shields 1. A pull rod 30 is symmetrically provided on the upper part of the central front shield 1, and pull rods 30 are also provided on the rear side of the side shields 4 located at the upper and lower parts on both sides. Four corner levers 31 are fixed to the bottom of each pull rod 30. Both the side shield plate 4 and the central front shield plate 1 have slots at the top. The bottom of the pull rod 30 is fixed with four corner levers 31, and the four corner levers 31 are slidably connected to the slots of the corresponding front shield plate 1 or side shield plate 4. The lower outer side of the pull rod 30 is fitted with a telescopic spring 32, and the telescopic spring 32 is connected between the pull rod 30 and the corresponding front shield plate 1 or side shield plate 4. The lower front side of the central front shield plate 1 is symmetrically provided with guide rails 8, and the two guide rails 8 are slidably connected with sliders 6. The two sliders 6 are connected with a webbing 7. The upper front side of the central front shield plate 1 is rotatably connected with a handle 9. The energy-absorbing plate 2 is made of ultra-high molecular weight polyethylene material with strong impact resistance and good durability.
