Abstract
Description
Technical Field
[0001] This utility model relates to the field of safety protection equipment technology, and in particular to a three-section foldable rigid bulletproof shield. Background Technology
[0002] In modern law enforcement and counter-terrorism operations, bulletproof shields serve as essential protective equipment for frontline personnel. Whether responding to sudden terrorist attacks, handling high-risk criminal incidents, or carrying out routine patrols, bulletproof shields are an indispensable tool for protecting the lives of law enforcement officers.
[0003] Currently, some bulletproof shields employ a foldable design to enhance their portability and mobility. This design allows the shield to be transported and deployed more quickly without sacrificing protective performance. However, most existing foldable rigid bulletproof shields use hinges to connect the shield plates. When unfolded, if supported only by the hinges, the shield is prone to slight wobbling or structural deformation, affecting its stability. Furthermore, when folded, without additional securing devices, the shield may accidentally unfold due to external forces or vibrations, impacting carrying safety and rapid deployment efficiency.
[0004] Therefore, a three-section foldable rigid bulletproof shield needs to be designed. Utility Model Content
[0005] In order to overcome the shortcomings of existing foldable bulletproof shields in that they lack effective locking in both unfolded and folded states, this utility model provides a three-section foldable rigid bulletproof shield.
[0006] The technical solution is as follows: A three-section foldable rigid bulletproof shield includes a main shield plate, a right shield plate, a left shield plate, a folding locking mechanism, a fixed plate, a rotating plate, an unfolding locking mechanism, a handle, and an observation window. The main shield plate has a left shield plate and a right shield plate on its left and right sides respectively. The left and right shield plates are arranged symmetrically, and a folding locking mechanism is provided between the left and right shield plates. Multiple fixed plates are fixedly connected to the left and right sides of the rear of the main shield plate. Rotating plates are rotatably connected to the fixed plates. The rotating plates are connected to the left and right shield plates on the same side. An unfolding locking mechanism is provided between the fixed plates and the rotating plates. Two handles are fixedly connected to the rear of the main shield plate, and an observation window is installed on the upper part of the main shield plate.
[0007] Preferably, the folding locking mechanism includes a wedge-shaped locking block, a first elastic element, a push block, and a second elastic element. Two wedge-shaped locking blocks are slidably provided in the middle of the right shield plate, and the first elastic element is connected between the wedge-shaped locking blocks and the right shield plate. Two locking slots are provided in the middle of the left shield plate, and the wedge-shaped locking blocks are locked into the slots. A push block is slidably provided in the middle of the left shield plate, wherein the push block slides in the slot and is aligned with the wedge-shaped locking blocks. The second elastic element is connected between the push block and the left shield plate.
[0008] Preferably, the locking mechanism includes a locking rod, a cam, a limiting block, and a third elastic element. The locking rod is rotatably connected to the fixed plate, and the locking rod abuts against the rotating plate. The locking rod is connected to the pivot of the locking rod. The main shield plate is slidably provided with a limiting block, which is concave in shape and engages with the cam. The limiting block is connected to the main shield plate with a third elastic element.
[0009] Preferably, it also includes a cushioning pad, with a cushioning pad located on the rear side of the main shield plate, between the two handles.
[0010] As a preferred option, it also includes support legs, with support legs rotatably installed on both the left and right sides of the rear of the main shield plate.
[0011] As a preferred option, the handle is made of rubber and the observation window is made of bulletproof glass.
[0012] Beneficial effects:
[0013] 1. This utility model achieves reliable locking in the folded state through the wedge-shaped locking block and slot cooperation structure of the folding locking mechanism, preventing accidental unfolding due to external force or vibration.

Detailed Implementation
[0021] Example: A three-section foldable rigid bulletproof shield, such as Figures 1-5 As shown, the shield includes a main shield plate 1, a right shield plate 2, a left shield plate 3, a folding locking mechanism, a fixed plate 4, a rotating plate 5, an unfolding locking mechanism, a handle 6, and an observation window 7. The main shield plate 1 has a left shield plate 3 and a right shield plate 2 on its left and right sides, respectively. The left shield plate 3 and the right shield plate 2 are arranged symmetrically, and a folding locking mechanism is provided between the left shield plate 3 and the right shield plate 2. Multiple fixed plates 4 are fixed to the left and right sides of the rear of the main shield plate 1. Rotating plates 5 are rotatably connected to the fixed plates 4. The rotating plates 5 are connected to the left shield plate 3 and the right shield plate 2 on the same side. An unfolding locking mechanism is provided between the fixed plates 4 and the rotating plates 5. Two handles 6 are fixed to the rear of the main shield plate 1. The handles 6 are made of rubber and provide a stable grip support point. The rubber material enhances grip stability and comfort. An observation window 7 is installed on the upper part of the main shield plate 1. The observation window 7 is bulletproof glass, which allows the user to observe the external situation while maintaining protection, improving tactical judgment and response capabilities.
[0022] like Figure 3 and Figure 4 As shown, the folding locking mechanism includes a wedge-shaped locking block 8, a first elastic element 9, a push block 10, and a second elastic element 11. Two wedge-shaped locking blocks 8 are slidably provided in the middle of the right shield plate 2, and the first elastic element 9 is connected between the wedge-shaped locking blocks 8 and the right shield plate 2. Two locking slots are provided in the middle of the left shield plate 3, and the wedge-shaped locking blocks 8 are locked into the slots. The push block 10 is slidably provided in the middle of the left shield plate 3, wherein the push block 10 slides in the slot, and the push block 10 is aligned with the wedge-shaped locking blocks 8. The second elastic element 11 is connected between the push block 10 and the left shield plate 3.
[0023] like Figure 5 As shown, the locking mechanism includes a locking rod 12, a cam 13, a limiting block 14, and a third elastic element 15. The locking rod 12 is rotatably connected to the fixed plate 4, and the locking rod 12 abuts against the rotating plate 5. The cam 13 is connected to the pivot of the locking rod 12. The limiting block 14 is slidably provided on the main shield plate 1. The limiting block 14 is concave and is engaged with the cam 13. The third elastic element 15 is connected between the limiting block 14 and the main shield plate 1.
[0024] like Figure 2As shown, it also includes a cushioning pad 16 and a support leg 17. The cushioning pad 16 is located on the rear side of the main shield plate 1. The cushioning pad 16 is located between the two handles 6, conforming to the user's body, reducing impact and improving shield holding comfort. The support legs 17 are rotatably installed on the left and right sides of the rear of the main shield plate 1, providing additional support when the shield is erected, enhancing overall stability, and suitable for long-term protection missions.
[0025] In actual use, the shield is initially folded. The wedge-shaped locking block 8 on the right shield plate 2 engages with the locking groove on the left shield plate 3 to lock and secure the folded shield, preventing accidental unfolding due to external force or vibration. When the shield needs to be unfolded, the user pushes the push block 10, compresses the second elastic element 11, and pushes the wedge-shaped locking block 8 to disengage it from the locking groove, thereby unlocking the left shield plate 3 and the right shield plate 2. Then, the user can rotate the left shield plate 3 and the right shield plate 2 along the rotating plate 5 to unfold them.
[0026] After unfolding, the user rotates the locking lever 12 on the fixed plate 4 towards the rotating plate 5. At this time, the locking lever 12 drives the cam 13 to rotate synchronously. As the cam 13 rotates, its outer edge gradually contacts the limiting block 14 and applies downward pressure. Since the limiting block 14 has a concave structure, the cam 13 gradually embeds itself into the groove while pressing down on the limiting block 14, at which time the third elastic element 15 is compressed. When the cam 13 is fully embedded in the groove, the third elastic element 15 recovers its deformation and provides a reverse force, so that the cam 13 is stably locked in the limiting block 14, thereby achieving the locking and limiting of the rotating plate 5. Through the above operation, the left shield plate 3 and the right shield plate 2 are firmly locked in the unfolded position, ensuring that the shield as a whole has good structural rigidity and impact resistance. The entire device is compact, easy to operate, and reliable in function, and is particularly suitable for the practical needs of modern law enforcement and counter-terrorism missions that require both high mobility and high protection.
