Description

Technical Field

[0001] This application relates to the field of shield technology, and more specifically, to an explosion-proof shield. Background Technology

[0002] Explosion-proof shields are protective equipment used to protect personnel from threats such as explosive fragments, impact objects, and projectiles when handling emergencies. They have high impact resistance and ensure personnel safety.

[0003] When traditional shields are threatened by explosive fragments or impact objects, their planar structure can cause the impact force to concentrate at a single point, potentially leading to shield breakage or localized damage and affecting their protective effectiveness. Furthermore, the lack of effective cushioning when the impact energy is transmitted to the shield user can easily cause arm tremors or injury.

[0004] In view of this, this application proposes an explosion-proof shield. Utility Model Content

[0005] The purpose of this application is to provide an explosion-proof shield that solves the technical problems mentioned in the background art.

[0006] This application provides an explosion-proof shield, including a shield back plate. An explosion-proof shield plate is fixedly connected to the front end of the shield back plate, a gripping mechanism is provided above the rear end of the shield back plate, and a fixing mechanism is provided below the rear end of the shield back plate.

[0007] The fixing mechanism includes a support plate located below the rear end face of the shield back plate. An anti-slip friction plate is fixedly connected to the end face of the support plate away from the shield back plate. A flipping cylinder is fixedly connected to the lower end face of the support plate. Fixed blocks are rotatably connected to both ends of the flipping cylinder, and the fixed blocks are fixedly connected to the support plate. A fixed column is provided inside the flipping cylinder, and the two ends of the fixed column are fixedly connected to the two fixed blocks respectively.

[0008] Optionally, the gripping mechanism includes a pad fixedly connected to the upper rear end face of the shield backplate, and a handle is fixedly connected to one side of the pad.

[0009] Optionally, an arc-shaped strip is fixedly connected to the other side of the pad, and a pile piece is fixedly connected to the outer wall of the arc-shaped strip.

[0010] Optionally, the lower end of the arc-shaped strip is hinged with a strap, and barbs are sewn onto the lower part of the strap away from the shield back plate. A retaining ring is fixedly connected to the lower part of the other side of the pad.

[0011] Optionally, a torsion spring is sleeved around the fixed column, one end of the torsion spring is fixedly connected to the fixed column, and the other end of the torsion spring is fixedly connected to the flipping cylinder.

[0012] Optionally, the explosion-proof shield plate is internally fixedly connected with a connecting strip, and both sides of the explosion-proof shield plate are fixedly connected with a buffer hard rubber strip, and both the connecting strip and the buffer hard rubber strip are attached to the shield back plate.

[0013] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0014] 1. This application utilizes an arc-shaped blast-resistant shield plate installed at the front end of the shield backplate. The arc design of the shield plate disperses the impact force along the curved surface throughout the entire shield frame, preventing concentrated stress at a single point and subsequent breakage. This structure evenly transmits the impact force to the shield backplate, reducing the risk of localized damage, improving the overall impact resistance of the shield, and effectively protecting the shield user. A buffer strip and connecting strip are installed in the hollow area between the blast-resistant shield plate and the shield backplate. Upon impact, the buffer strip and connecting strip absorb energy through compression deformation, prolonging the impact duration and reducing the peak instantaneous impact force. This design significantly weakens shock transmission, preventing the shield user from arm tremors or injury due to severe impact.

[0015] 2. This application requires the shield to be placed vertically on the ground. When the user steps on the support plate, the flipping cylinder and anti-slip friction plate flip and land. The tiny spikes on the surface of the anti-slip friction plate embed into the ground, and together with the elasticity of the torsion spring, provide strong friction, making the shield stand firmly on the ground and not easily pushed over or shifted by external forces. After use, releasing the foot on the support plate causes the torsion spring to automatically return to its original position, retracting the anti-slip friction plate without affecting the shield's portability and regular use. This significantly improves the shield's conversion efficiency in different combat scenarios. Attached Figure Description

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] Reference Figures 1-3 This application provides an explosion-proof shield, including a shield back plate 1, an explosion-proof shield plate 2 fixedly connected to the front end of the shield back plate 1, a gripping mechanism 3 located above the rear end of the shield back plate 1, and a fixing mechanism 4 located below the rear end of the shield back plate 1. The arc-shaped design of the explosion-proof shield plate 2 disperses the impact force along the curved surface to the entire shield frame, avoiding concentrated force at a single point that could lead to breakage. This structure evenly transmits the impact force to the shield back plate 1, reducing the risk of localized damage, improving the overall impact resistance of the shield, and effectively protecting the safety of the shield user.

[0022] The explosion-proof shield plate 2 is internally connected with connecting strips 5, and buffer hard rubber strips 6 are fixedly connected to both sides of the interior of the explosion-proof shield plate 2. Both the connecting strips 5 and the buffer hard rubber strips 6 are attached to the shield back plate 1. The buffer hard rubber strips 6 and connecting strips 5 are installed in the hollow area between the explosion-proof shield plate 2 and the shield back plate 1. When subjected to impact, the buffer hard rubber strips 6 and connecting strips 5 absorb energy through compression deformation, prolonging the impact time and reducing the peak instantaneous impact force. This design can significantly weaken the shock transmission and prevent the shield holder from experiencing arm tremors or injury due to severe impact.

[0023] The fixing mechanism 4 includes a support plate 401 located below the rear end face of the shield back plate 1. An anti-slip friction plate 402 is fixedly connected to the end face of the support plate 401 away from the shield back plate 1. A flipping cylinder 403 is fixedly connected to the lower end face of the support plate 401. Fixing blocks 404 are rotatably connected to both ends of the flipping cylinder 403, and the fixing blocks 404 are fixedly connected to the support plate 401. A fixing post 405 is provided inside the flipping cylinder 403, and the two ends of the fixing post 405 are fixedly connected to the two fixing blocks 404 respectively. A torsion spring 406 is sleeved around the fixing post 405. One end of the torsion spring 406 is fixedly connected to the fixing post 405, and the other end of the torsion spring 406 is fixedly connected to the flipping cylinder 403. When the shield is placed vertically on the ground, the user steps on the support plate 401, which causes the flipping cylinder 403 and the anti-slip friction plate 402 to flip and land. The tiny spikes on the surface of the anti-slip friction plate 402 embed into the ground, and together with the elasticity of the torsion spring 406, provide strong friction, keeping the shield firmly planted on the ground and preventing it from being pushed over or shifted by external forces. After use, releasing the foot on the support plate 401 causes the torsion spring 406 to automatically return to its original position, retracting the anti-slip friction plate 402 without affecting the shield's portability and regular use. This significantly improves the shield's efficiency in different combat scenarios.

[0024] The gripping mechanism 3 includes a pad 301 fixedly connected to the upper rear end face of the shield back plate 1. A handle 302 is fixedly connected to one side of the pad 301, and an arc-shaped strip 303 is fixedly connected to the other side of the pad 301. A fleece piece 304 is fixedly connected to the outer wall of the arc-shaped strip 303. A strap 305 is hinged to the lower end of the arc-shaped strip 303. A barbed piece 306 is sewn onto the lower part of the strap 305 away from the end face of the shield back plate 1. A retaining ring 307 is fixedly connected to the lower part of the other side of the pad 301. The user puts on the shield through the arc-shaped strip 303 and the handle 302 on the pad 301, and passes the strap 305 through the retaining ring 307. The tightness can be adjusted according to the arm size using the Velcro structure of the barbed piece 306 and the fleece piece 304 to ensure a secure fit and prevent the shield from falling off during vigorous movements. This design can meet the needs of high-intensity activities while avoiding the problem of poor blood circulation caused by traditional tight binding.

[0025] The pad 301 is in direct contact with the arm. It is made of soft material and has a certain cushioning performance, reducing the pressure of wearing it for a long time. The arc strip 303 conforms to the curve of the arm, distributing the weight of the shield and further improving comfort, allowing the shield user to maintain a combat state for a long time.

[0026] Working principle: The user can pass their arm through the arc-shaped strip 303 on the pad 301, hold the handle 302, pass the strap 305 on the arc-shaped strip 303 through the retaining ring 307, tighten the strap 305, and fit the arc-shaped strip 303 against their arm. Then, attach the barbs 306 on the strap 305 to the fleece pieces 304 on the arc-shaped strip 303, thus installing the blast shield onto the arm. It is not easy to fall off. At the same time, the pad 301 can conform to the arm, improving comfort and providing a certain cushioning effect. The front end of the shield back plate 1 is equipped with an arc-shaped blast shield plate 2. The blast shield plate 2 and the shield back plate 1 are hollow. When the arc-shaped blast shield plate 2 is impacted, the arc surface can disperse the impact force along the curved surface to the entire shield frame, avoiding excessive force at a single point that could cause breakage. The hollow area between the explosion-proof shield plate 2 and the shield back plate 1 is provided with a pair of buffer hard rubber strips 6 and connecting strips 5. When an impact occurs, the hollow layer absorbs energy through the compression deformation of the buffer hard rubber strips 6 and connecting strips 5, prolongs the impact time, and further reduces the instantaneous impact peak, thereby protecting the shield holder from shock injury.

[0027] When the shield needs to be placed vertically and stably on the ground, the user holds the handle 302 and the curved strip 303 with both hands, places the blast shield plate 2 vertically on the ground, and steps on the support plate 401, causing the support plate 401, the flipping cylinder 403 and the anti-slip friction plate 402 to flip, so that the anti-slip friction plate 402 is in contact with the ground. The torsion spring 406 deforms and generates elasticity. The surface of the anti-slip friction plate 402 has a large number of small spikes. When the user steps on it, the anti-slip friction plate 402 is in close contact with the ground. The anti-slip friction plate 402 plays a good role in preventing slippage and stabilization, so that the shield back plate 1 and the blast shield plate 2 are not easy to shift during use. When not in use, the user no longer steps on the support plate 401, the torsion spring 406 rebounds, and the flipping cylinder 403, the support plate 401 and the anti-slip friction plate 402 are flipped back to their initial positions.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
