Description

Technical Field

[0001] This utility model relates to the field of riot shield technology, and in particular to a riot shield with good impact resistance. Background Technology

[0002] Riot shields are defensive equipment used by armed police to push away others and protect themselves during riot control operations. They can withstand attacks from hard objects, blunt instruments, and unidentified liquids, as well as low-velocity bullets. They have good impact resistance, therefore, riot shields with good impact resistance are required.

[0003] According to the description in the patent application (CN217083498U) regarding a police riot shield with good impact resistance, "This utility model provides a police riot shield with good impact resistance, relating to the field of police equipment technology. The police riot shield with good impact resistance includes a riot shield body, with two reinforcing plates fixedly connected to one side of the riot shield body. The two reinforcing plates are symmetrically distributed with respect to the vertical center line of the riot shield body. A connecting seat is provided on one side of the riot shield body. In this police riot shield with good impact resistance, multiple square rods are slidably connected to the connecting seat through multiple square grooves. Due to the elastic compression and buffering effect of multiple buffer springs, the impact resistance of the riot shield body is improved on the one hand, and the impact force received by the user is reduced on the other hand. The two reinforcing plates fixedly connected to one side of the riot shield body further improve the strength of the riot shield body and enhance the protective effect of the riot shield body on the user."

[0004] Regarding the above description, the applicant believes the following issues exist: Multiple square rods are slidably connected to the connecting seats via multiple square slots. Due to the elastic compression and cushioning effect of the buffer springs, this design not only improves the impact resistance of the riot shield body but also effectively reduces the impact force on the user. Furthermore, two reinforcing plates are fixedly connected to one side of the riot shield body. This further enhances the strength of the riot shield body and improves its protective capability. However, this device has a drawback: its overall structure is fixed and cannot be adjusted according to actual needs. It cannot adjust the size of the protective equipment according to individual body size or specific usage scenarios, which may affect the protective effect and user comfort to some extent. Utility Model Content

[0005] To overcome the problem that the size of protective equipment cannot be adjusted according to actual needs, or according to individual body shape or specific usage scenarios, which may affect the protective effect and user comfort.

[0006] The technical solution of this utility model is as follows: a riot shield with good impact resistance, including a riot shield plate; it also includes a mounting box and a fixing component. The mounting box is fixedly connected inside the riot shield plate. The fixing component is provided on the front of the riot shield plate. A rotating plate is rotatably connected inside the riot shield plate. A limit plate is fixedly connected to the outside of the rotating plate. A ratchet block is rotatably connected inside the mounting box. A spring is provided at the middle position between the outside of the ratchet block and the inside of the mounting box. A ratchet wheel is rotatably connected inside the mounting box. A gear is fixedly connected to the outside of the ratchet wheel. A toothed plate is meshed with the outside of the gear. An adjusting plate is fixedly connected to the toothed plate. A toothed plate is meshed with the end of the gear away from the toothed plate. An adjusting plate is fixedly connected to the outside of the toothed plate.

[0007] Preferably, the riot shield plate and the corresponding positions of the adjusting plate one and adjusting plate two are provided with sliding grooves, and the adjusting plate one and adjusting plate two are slidably connected inside the riot shield plate.

[0008] Preferably, the riot shield plate has a sliding groove at the corresponding position of toothed plate one and toothed plate two, and toothed plate one and toothed plate two are slidably connected inside the riot shield plate.

[0009] Preferably, a through hole is provided at the corresponding position of the mounting box and the gear, and the gear is rotatably connected inside the mounting box.

[0010] Preferably, there are two sets of ratchet blocks and springs, which are symmetrically arranged on the outside of the ratchet.

[0011] Preferably, the mounting box and the limiting plate are provided with through holes at corresponding positions, and the limiting plate is rotatably connected inside the mounting box.

[0012] Preferably, the fixing component includes a grip handle, which is fixedly connected to the front of the riot shield plate. An adjustment strap is fixedly connected to the front of the riot shield plate, and a buckle is provided on the outside of the buckle.

[0013] The beneficial effects of this utility model are as follows: By rotating the rotating plate, it causes the limiting plate to rotate until it contacts one side of a set of ratchet blocks. At this time, a set of springs pushes the ratchet blocks to abut against the limiting plate. Then, the adjusting plate two is pulled, causing the gear outside the toothed plate two to start rotating. The rotation of the gear then causes the adjusting plate one outside the toothed plate one to slide inside the riot shield. Through this operation, adjusting plate two and adjusting plate one can slide out from inside the riot shield, thereby adjusting the size of the device. After the size adjustment is completed, the rotating plate is reset. At this time, the two sets of springs push the ratchet blocks to restrict the ratchet, ensuring that the adjusted state of the riot shield is maintained. This adjustment mechanism is conducive to adjusting the size of the protective equipment according to individual body size or specific usage scenarios, thereby improving the protective effect and user comfort.

[0022] Please see Figures 1-6This utility model provides an embodiment of a riot shield with good impact resistance, including a riot shield plate 1; it also includes a mounting box 21 and a fixing component. The mounting box 21 is fixedly connected inside the riot shield plate 1. The fixing component is provided on the front of the riot shield plate 1. A rotating plate 22 is rotatably connected inside the riot shield plate 1. A limit plate 23 is fixedly connected to the outside of the rotating plate 22. A ratchet block 24 is rotatably connected inside the mounting box 21. A spring 25 is provided at the middle position between the outside of the ratchet block 24 and the inside of the mounting box 21. A ratchet wheel 26 is rotatably connected inside the mounting box 21. A gear 27 is fixedly connected to the outside of the ratchet wheel 26. A toothed plate 28 meshes with the outside of the gear 27. An adjustment mechanism is fixedly connected to the toothed plate 28. A gear 27, located on the outer side of a gear 29 away from the gear 28, meshes with a gear 210. An adjusting plate 211 is fixedly connected to the outer side of the gear 210. Rotating the rotating plate 22 causes the limiting plate 23 to rotate to one side of a set of ratchet blocks 24. This causes a set of springs 25 to push the ratchet blocks 24 against the limiting plate 23, pulling the adjusting plate 211. The adjusting plate 211 then drives the gear 27 outside the gear 210 to rotate. The gear 27 causes the adjusting plate 29 outside the gear 28 to slide inside the riot shield plate 1. This allows the adjusting plate 211 and adjusting plate 29 to slide out of the riot shield plate 1, adjusting the size of the device. The rotating plate 22 is then reset, and the two sets of springs... Spring 25 pushes ratchet block 24 to restrict ratchet 26, thereby completing the adjustment of riot shield plate 1; slid grooves are provided at corresponding positions of riot shield plate 1 and adjusting plate 1 29 and adjusting plate 211, and adjusting plate 1 29 and adjusting plate 211 are slidably connected inside riot shield plate 1. The presence of riot shield plate 1 facilitates the provision of an installation base for other components; slid grooves are provided at corresponding positions of riot shield plate 1 and toothed plate 1 28 and toothed plate 210, and toothed plate 1 28 and toothed plate 210 are slidably connected inside riot shield plate 1. The presence of toothed plate 1 28 and toothed plate 210 facilitates the rotation of gear 27, allowing adjusting plate 1 29 and adjusting plate 211 to slide out of the interior of riot shield plate 1. The installation of the riot shield plate 1 helps protect the user. A through hole is provided at the corresponding position of the mounting box 21 and the gear 27, with the gear 27 rotatably connected inside the mounting box 21. The mounting box 21 provides a foundation for other components. Two sets of ratchet blocks 24 and springs 25 are provided, symmetrically arranged outside the ratchet wheel 26. The springs 25 help to restrict the rotation of the ratchet wheel 26 in conjunction with the ratchet blocks 24. A through hole is provided at the corresponding position of the mounting box 21 and the limiting plate 23, with the limiting plate 23 rotatably connected inside the mounting box 21. The limiting plate 23 helps to restrict the ratchet blocks 24 in conjunction with the springs 25.

An adjustment strap 32 is fixedly connected to the front of the riot shield plate 1, and a buckle 33 is provided on the outside of the buckle 33. The grip handle 31 is provided to facilitate the user's grip.

[0024] During operation, the riot shield 1 is secured to the arm by gripping the handle 31 and using the adjusting belt 32 in conjunction with the buckle 33. Then, by rotating the rotating plate 22, the limiting plate 23 is rotated to the side of a set of ratchet blocks 24. A set of springs 25 pushes the ratchet blocks 24 to abut against the limiting plate 23, pulling the adjusting plate 211. The adjusting plate 211 drives the gear 27 outside the toothed plate 210 to rotate. The gear 27 drives the adjusting plate 29 outside the toothed plate 28 to slide inside the riot shield 1, thereby allowing the adjusting plate 211 and adjusting plate 29 to slide out from inside the riot shield 1. The size of the adjusting device is adjusted by resetting the rotating plate 22 and having the two sets of springs 25 push the ratchet blocks 24 to restrict the ratchet wheel 26, thus completing the adjustment of the riot shield 1.

[0025] Through the above steps, by rotating the rotating plate 22, it causes the limiting plate 23 to rotate until it contacts one side of a set of ratchet blocks 24. At this time, a set of springs 25 pushes the ratchet blocks 24 to abut against the limiting plate 23. Then, the adjusting plate 211 is pulled, causing the gear 27 outside the toothed plate 210 to start rotating. The rotation of the gear 27 then causes the adjusting plate 29 outside the toothed plate 28 to slide inside the riot shield plate 1. Through this operation, the adjusting plate 211 and the adjusting plate 29 can slide out from inside the riot shield plate 1, thereby adjusting the size of the device. After the size adjustment is completed, the rotating plate 22 is reset. At this time, the two sets of springs 25 push the ratchet blocks 24 to restrict the ratchet 26, ensuring that the adjusted state of the riot shield plate 1 is maintained. This adjustment mechanism is beneficial for adjusting the size of protective equipment according to individual body size or specific usage scenarios, thereby improving the protective effect and user comfort.
