Description

Technical Field

[0001] This utility model relates to the field of defense equipment technology, specifically to a riot shield. Background Technology

[0002] Riot shields are key equipment in the fields of public safety, counter-terrorism and emergency response, and military protection. Their core function is to protect the user's life by using physical barriers to resist the impact of explosions, shrapnel, projectiles and violent impacts.

[0003] Currently, existing riot shields have shortcomings in terms of functional expansion, especially in their weak defense capabilities against sudden close-quarters combat scenarios. When faced with violent attacks by terrorists, police or armed police officers must rely on shields to directly confront the terrorists' bodies. When there are many terrorists and they continue to launch violent attacks, our personnel will suffer excessive physical exhaustion and lose control of the situation, thereby emboldening the terrorists to rely on physical assaults. Utility Model Content

[0004] The purpose of this invention is to provide a riot shield to solve the problems mentioned in the background art, such as the weak defensive capabilities against sudden close combat scenarios.

[0005] To achieve the above objectives, this utility model provides a riot shield, including a shield body and a protruding area assembly. The shield body has an opening, the opening direction of which is consistent with the thickness direction of the shield body. The protruding area assembly is inserted into the shield opening and includes a protruding fixing component and a protruding body. The protruding fixing component is slidably installed within the shield opening and can slide between a first preset position and a second preset position. One end of the protruding body is fixedly connected to the side of the protruding fixing component facing away from the user, and the other end has a pointed tip.

[0006] Furthermore, the first preset position is where the protrusion is fully embedded in the surface of the shield body on the side away from the user, and the second preset position is where the protrusion extends out of the surface of the shield body on the side away from the user.

[0007] Furthermore, the riot shield also includes a power unit, which is fixed on the side of the shield body closer to the user and is used to provide power for the protruding area components to move from a first preset position to a second preset position.

[0008] Furthermore, the power unit includes a cylinder, a piston, an inflation port, a deflation port, and electrodes. The cylinder is a barrel structure with one open end. The piston is slidably mounted inside the cylinder, dividing the interior of the barrel into a sealed cavity and an open cavity. The motors for both the inflation port and deflation port are mounted on the cylinder and are connected to the sealed cavity, which is located within the sealed cavity. The opening of the cylinder is fixed to the surface of the shield body near the user, and the cylinder opening communicates with the shield opening. A protruding fixing component can slide between the shield opening and the cylinder. The piston, facing the open cavity, is fixedly connected to the protruding fixing component.

[0009] Furthermore, the power unit also includes a piston rod, which is disposed between the piston and the protruding fixing component, and the piston and the protruding fixing component are fixedly connected by the piston rod.

[0010] Furthermore, the protruding fixing component is a cylindrical structure; the protrusion is serrated, including a conical segment and a cylindrical segment, and the central axis of the conical segment coincides with the central axis of the cylindrical segment. One end of the cylindrical segment is fixedly connected to the protruding fixing component, and the other end of the cylindrical segment is connected to the cone bottom of the conical segment, and the diameter of the bottom surface of the cylindrical segment is the same as the diameter of the cone bottom of the conical segment.

[0011] Furthermore, the riot shield also includes a limiting component, which is fixed to the side of the shield opening away from the user, to prevent the protruding area components from detaching from the shield body from the side away from the user.

[0012] Furthermore, a viewing window is provided on the main body of the shield.

[0013] Furthermore, the riot shield also includes a hand-held component, which consists of a grip and a securing strap, both of which are fixed to the center of the shield body on the side closest to the user.

[0014] Furthermore, the riot shield also includes a ground support component, which includes support legs and connecting blocks. The connecting blocks fix the upper inner side of the shield body, and the ground support component is used to provide support for the wolf tooth protective shield to be placed on the ground.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. This utility model features a protruding area component on the shield body. These protrusions create a psychological deterrent against terrorists, reducing their willingness to engage in a frontal assault, enhancing defensive effectiveness, forcing them to maintain distance, avoiding direct collisions, and reducing the risk of close-quarters combat. In close-quarters combat, the shield's spikes can be used to hinder the opponent's approach when pushed, even forcing them to retreat, thus gaining the user the initiative.

[0017] 2. This utility model ignites the combustible gas in the cylinder cavity, causing a rapid increase in the air pressure inside the cavity, thereby quickly pushing the protruding area component out, realizing a rapid conversion from a safe state to a deterrent state. It can be reused by refilling with combustible gas. It is easy to operate and responds quickly. Daily maintenance only requires periodic lubrication and inspection of mechanical parts, and the cost is low.

[0018] 3. This utility model can switch between a safe state and a deterrent state. In the safe state, the protrusion is fully embedded in the surface of the shield body on the side furthest from the user, and it can be used as a regular riot shield. In the deterrent state, the protrusion extends beyond the surface of the shield body on the side furthest from the user, and can deter terrorists from maintaining distance when they appear. By switching between the safe and deterrent states, it adapts to different scenarios, expanding the scope of application of this utility model and improving its operational flexibility.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0027] like Figures 1 to 5As shown, an embodiment of this utility model provides a riot shield, including a shield body 1 and a protruding area assembly 2. The shield body 1 has a shield opening 31, the opening direction of which is consistent with the thickness direction of the shield body 1. The protruding area assembly 2 is inserted into the shield opening 31, and includes a protruding fixing member 21 and a protruding body 22. The protruding fixing member 21 is slidably installed within the shield opening 31 and can slide between a first preset position and a second preset position. One end of the protruding body is fixedly connected to the side of the protruding fixing member facing away from the user, and the other end is provided with a pointed tip.

[0028] The shield body 1 can adopt either a convex arc-shaped structure or a flat structure. In this embodiment, the shield body 1 adopts a convex arc-shaped structure, which can better resist the impact force during confrontation. The shield body 1 is provided with a protruding area component 2. The protrusion 21 forms a psychological deterrent to terrorists, thereby reducing their willingness to conduct a frontal assault and improving our defensive effectiveness. This embodiment is typically used in military or police scenarios.

[0029] The first preset position is where the protrusion 22 is fully embedded in the surface of the shield body 1 on the side away from the user, and the second preset position is where the protrusion 22 extends out of the surface of the shield body 1 on the side away from the user.

[0030] When the protruding area component 2 is in the first preset position, the riot shield is in a safe state; when the protruding area component 2 is in the second preset position, the riot shield is in a deterrent state. In the safe state, the riot shield can be used as a regular riot shield or stored away when not in use. In the deterrent state, the protrusions 22 extending beyond the surface of the shield body 1 can be used to deter terrorists and prevent physical contact and confrontation with them.

[0031] In this embodiment, the riot shield also includes a power unit 4, which is fixed to the side of the shield body 1 closest to the user and is used to provide power for the protruding area component 2 to move from a first preset position to a second preset position. The power unit 4 can be a pneumatic drive or an electric drive. The pneumatic drive can be a cylinder, which has strong explosive force, extremely fast response, and no electrical dependence, but requires the carrying of flammable materials for replenishment; the electric drive can be a DC motor driving a gear set or a screw control structure for extension and retraction, which has fast response and a compact structure, but depends on a stable power supply.

[0032] like Figure 4 and Figure 5As shown, the power unit 4 includes a cylinder 41, a piston 42, an air inlet 44, a vent 45, and an electrode 46. The cylinder 41 is a barrel structure with one open end. The piston 42 is slidably disposed inside the cylinder 41, dividing the interior of the cylinder 41 into a sealed cavity and an open cavity. The air inlet 44 and the vent 45 are both disposed on the cylinder 41, and both the air inlet 44 and the vent 45 are connected to the sealed cavity. The electrode 46 is disposed inside the sealed cavity and is used to ignite the flammable material inside the sealed cavity. The opening of the cylinder 41 is fixed to the surface of the shield body 1 near the user, and the opening of the cylinder 41 communicates with the shield opening 31. The protruding fixing component 21 can slide between the shield opening 31 and the cylinder 41. The piston 42 is fixedly connected to the protruding fixing component 21 on the side facing the open cavity.

[0033] In this embodiment, the power unit 4 can be a pneumatic drive device, specifically a cylinder. The cylinder body 41 and the shield body 1 can be connected by welding or by setting matching threads. The opening of the cylinder body 41 has the same inner diameter as the shield opening 31, and the opening of the cylinder body 41 is fixed to the surface of the shield body 1 near the user, so that the opening of the cylinder body 41 and the shield opening 31 are in communication. The protruding fixing component 21 can slide between the shield opening 31 and the cylinder body 41. The pneumatic drive device provides power for the riot shield to change from a safe state to a deterrent state. After filling the sealed cavity with combustible material or setting blank cartridges, the motor ignites the combustible material or fires the blank cartridges to make the pressure in the cavity increase sharply, thereby pushing the piston 2 to drive the piston rod 3, and quickly pushing out the protruding area component 2, so that the protruding body 22 extends outward, realizing the rapid change of the riot shield from a safe state to a deterrent state.

[0034] In this embodiment, the power device also includes a piston rod 43, which is disposed between the piston and the protrusion fixing component 21. The piston 42 and the protrusion fixing component 21 are fixedly connected by the piston rod 43, which increases the extension distance of the protrusion area assembly 2 and ensures that the protrusion 22 can extend beyond the surface of the shield body 1 away from the user.

[0035] In this embodiment, the protruding fixing component 21 is a cylindrical structure, and the protruding body 22 can be a wolf-tooth-shaped structure. Specifically, the structure can include a conical segment and a cylindrical segment, and the central axis of the conical segment coincides with the central axis of the cylindrical segment. One end of the cylindrical segment is fixedly connected to the protruding fixing component 21, and the other end of the cylindrical segment is connected to the cone bottom of the conical segment. The diameter of the bottom surface of the cylindrical segment is the same as the diameter of the cone bottom of the conical segment.

[0036] In this embodiment, the protruding fixing component 21 adopts a cylindrical structure. The axisymmetry of the cylindrical structure results in a continuous arc surface at the contact surface during sliding, leading to uniform friction distribution, effectively reducing the risk of jamming and extending service life. The protrusion 22 adopts a combination structure of a conical segment and a cylindrical segment, with the sharp part of the cone's apex rounded. The purpose of the protrusion 22 extending beyond the shield body 1 is to deter terrorists and avoid direct contact and confrontation, rather than to cause injury through an overly sharp protrusion 22. If terrorists insist on contacting the riot shield with their bodies, the rounded tip of the cone is sufficient to concentrate pressure at the tip, causing pain and achieving a deterrent effect.

[0037] like Figure 3 As shown, the riot shield also includes a limiting component 32, which is fixed to the side of the shield opening 31 away from the user, to prevent the protruding area assembly 2 from detaching from the shield body 1. The limiting component 32 limits the movement distance of the protruding fixing component 21, preventing it from moving outward and detaching from the shield body 1 after being pushed by the piston rod 43, thus rendering it ineffective. The limiting component 32 can be a ring structure, a retaining ring for the hole, or a protruding structure on the outside of the opening.

[0038] In this embodiment, the positioning component 32 can adopt a ring-shaped structure and be fixed to the side of the shield opening 31 away from the user by welding. The welding method is more secure and can prevent the positioning component 32 from falling off and failing due to collision with the protruding fixing component 21. When colliding with the protruding fixing component 21, the ring-shaped structure has a larger contact surface and the force is more evenly distributed during the collision, which can prevent structural damage to the protruding fixing component 21.

[0039] like Figure 1 As shown, the shield body 1 is provided with a viewing window 5. The shape of the viewing window 5 can be rectangular, circular, or other shapes, used to observe the situation in front from behind the shield. The viewing window 5 can be made by setting a protective cover of riot-proof glass or metal mesh structure in the opening of the viewing window 5 to protect the safety of personnel behind the shield.

[0040] In this embodiment, the riot shield also includes a handheld component 61, which includes a handle 63 and a fixing strap 64. Both the handle 63 and the fixing strap 64 are fixed to the middle of the surface of the shield body 1 on the side closest to the user. The handle 63 serves as the main grip point, bearing most of the weight of the shield and the impact force during combat. The fixing strap 64 is used to distribute the pressure of the handle 63, prevent the shield from slipping out of the hand, and improve stability.

[0041] like Figure 2As shown, in this embodiment, the riot shield also includes a ground support component 62. The ground support component 62 includes support legs 65 and connecting blocks 66. The connecting blocks 66 are fixed to the surface of the shield body 1 near the user, and the support legs 65 are hinged to the connecting blocks 66. The ground support component 62 can adopt a structure supported by the support legs 65. The hinge between the support legs 65 and the connecting blocks 66 enables the retraction and extension of the support legs 65. The connecting blocks 66 are bolted to the shield body 1, and the ends of the two support legs 65 away from the connecting blocks 66 are connected by a connecting rod 67 to increase stability during support. By bolting the connecting blocks 66 to the shield body 1, the ground support component 62 can be installed on the shield body 1 when it needs to be erected on the ground. When only handheld operation is required, the ground support component 62 can be removed to reduce the overall weight of the shield and reduce the pressure on the handheld shield.

[0042] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
