Description

TECHNICAL FIELD

[0001] The present application relates to the field of explosion-proof shields, and in particular to a multifunctional shield. BACKGROUND

[0002] Explosion-proof shields are a type of safety equipment, commonly used by law enforcement and military units in situations where there is a risk of rioting or other potential explosive threats. They are designed to protect the user from explosive fragments, shrapnel, stones, sticks, and even bullets in some cases;

[0003] However, the explosion-proof shields in the prior art have the following disadvantages:

[0004] Lack of adaptability: lack of adjustment mechanisms to adapt to different environments and defense needs, such as inability to adjust the degree of window obstruction or change the protective performance of the shield.

[0005] Response speed: when under attack, traditional shields cannot quickly enhance defense strength, lacking the ability to quickly respond and adaptively strengthen.

[0006] Limited observation function: existing shields do not integrate observation components, or these components have limited functionality, do not support dynamic adjustment or rotation to change the observation angle.

[0007] Weight and portability: old-style shields are heavy and not easy to carry, especially when not under attack, their weight affects mobility and flexibility.

[0008] Material and structure: the shields in the prior art are not sufficient in material or structure to provide adequate explosion-proof performance, or the improvement in explosion-proof performance is at the expense of portability and field of view. SUMMARY

[0009] The purpose of the present application is to provide a multifunctional shield to solve the problems raised in the background art.

[0010] Based on the above idea, the present application provides the following technical solution: a multifunctional shield, characterized in that it comprises:

[0011] a shell;

[0012] an adjustment assembly;

[0013] an enhancement assembly;

[0014] and an observation assembly;

[0015] The adjustment assembly is arranged at the middle position of the shell, and the adjustment assembly comprises a window and a baffle;

[0016] The enhancement assembly is arranged at one side of the shell and extends into the interior of the shell;

[0017] The observation component is rotatably mounted on the other side of the housing;

[0018] By changing the positional relationship between the baffle and the viewing window, the reinforcement component is driven to increase the strength of the outer shell and the limiting relationship between the observation component and the outer shell. When the shield bearer walks with the shield, the baffle is located inside the outer shell and does not obstruct the view through the viewing window. When attacked, the baffle can be rotated to the position of the viewing window to ensure the strength of the shield. At the same time, the reinforcement component is triggered to increase the strength of the shield, and the limiting change between the observation component and the outer shell is also triggered, allowing it to rotate relative to the outer shell. This makes it convenient for the person behind the shield to observe the external situation and remove the baton, transforming it from a convenient container for storing the baton into a convenient observation tool. This allows the shield bearer to achieve shield lightness when walking, while ensuring the strength of the shield when attacked, and also ensuring that the user's vision is not interfered with by the obstruction of the viewing window.

[0019] Preferably, the adjustment component further includes: a knob;

[0020] The outer casing is hollow, and the viewing window is located in the middle of the outer casing. The knob is rotatably connected to the lower side of the viewing window. The knob extends into the interior of the outer casing and is fixedly connected to the baffle. The size of the baffle corresponds to the viewing window. By rotating the knob, the position of the baffle can be made to correspond perfectly with the viewing window.

[0021] Preferably, the viewing window is made of tempered glass in the cutout of the outer casing, and the baffle is made of alloy material.

[0022] Preferably, the adjustment component further includes:

[0023] Gears, racks, and slides;

[0024] The gear is fixedly disposed in the middle of the connection position between the knob and the baffle. The lower side of the gear meshes with the rack. The inner wall of the housing is provided with a slide rail that slides with the rack.

[0025] Preferably, the enhancement component includes:

[0026] Pump body, rollers, connector, tubing, and cavity;

[0027] The cavity is located in the middle of the interior of the outer shell, the plug-in interface is located on one side of the outer shell and communicates with the cavity, the pump body is an external device, the pump body is connected to the plug-in interface through the through pipe, and the roller is rotatably located on the lower side of the pump body.

[0028] Preferably, the enhancement component further includes:

[0029] Valve body, fixed pulley, and traction rope;

[0030] The valve body is located at the point where the insertion port and the cavity pass through. One end of the traction rope is located at the end of the rack near the reinforcing component, and the other end of the traction rope is connected to the switch of the valve body. The fixed pulley is rotatably connected inside the housing, and the traction rope is wound around the fixed pulley. The pump body contains a high-strength Newtonian fluid. When the shield bearer is attacked and turns the knob, the rack moves, causing the traction rope to move along the fixed pulley, triggering the switch of the valve body, so that the non-Newtonian fluid inside the pump body rushes into the cavity to increase the shield strength.

[0031] Preferably, the observation component includes:

[0032] Main tube, observation tube, observation port, light inlet tube, lens, and spring;

[0033] The main tube is rotatably disposed on the side of the housing away from the reinforcing component. The observation tube is disposed on the lower side of the main tube, and the light inlet tube is disposed on the lower side of the main tube. The observation tube has an observation port. The main tube, the observation tube, and the light inlet tube are provided with lenses at special angles so that the light source entering through the light inlet tube can be observed through the observation port. The lens inside the main tube is connected to the inner wall of the main tube by the spring.

[0034] Preferably, the observation component further includes:

[0035] Rotary wheel, slot, lever, vertical bar, horizontal bar, and diagonal block;

[0036] The main tube and the outer casing are rotatably connected by the rotating wheel, which extends into the interior of the outer casing. The lower side of the rotating wheel is provided with the slot. The rack is fixedly provided with the crossbar on the side near the observation component. The lower side of the crossbar is provided with the inclined block. The inner wall of the outer casing near the observation component is provided with the vertical rod that slides up and down. The vertical rod is driven by the inclined block. The lower side of the vertical rod is provided with the locking rod that cooperates with the slot. An elastic element is provided between the connection position of the vertical rod and the outer casing to keep it in an upward force.

[0037] Preferably, it further includes:

[0038] The baton engages with the main tube when the rotating wheel is limited by the locking lever. When the baton engages with the main tube, it compresses the spring. If the shield-bearer is not attacked, and while walking with the shield, the upward force of the elastic element on the vertical rod causes the locking lever to engage with the locking slot, thus limiting the main tube. At this time, the main tube can serve as a container for storing the baton. The connection between the spring and the lens further facilitates the engagement of the baton. When the shield-bearer is attacked, the knob is turned, disengaging the main tube from the outer casing. The main tube rotates relative to the outer casing, allowing the baton to be removed. At this time, through the lens installed in the main tube, observation tube, and light inlet tube, the user can safely observe the external situation from behind the shield.

[0039] Preferably, it further includes:

[0040] Handle; the handle is fixedly disposed on the inside of the housing.

[0041] Compared with the prior art, the beneficial effects of the present invention are:

[0042] The adjustment component, located in the center of the outer shell, includes a viewing window and a baffle. The degree of occlusion of the viewing window can be adjusted by changing the position of the baffle. The reinforcement component, located on one side of the outer shell, increases its strength. The observation component, located on the other side of the outer shell, can rotate to allow the user to observe the outside environment. In the event of an attack, the baffle can rotate to face the viewing window to protect the shield, simultaneously activating the limit changes of the reinforcement and observation components to strengthen the shield and ensure the user's line of sight. The shield provides lightweight convenience for easy movement, offers necessary protection during attacks, and ensures an unobstructed view for the user.

[0043] The adjustment assembly also includes a knob, fixedly connected to the baffle, allowing the user to precisely adjust the relative position of the baffle and the viewing window by rotating the knob. The viewing window is made of tempered glass, while the baffle is made of an alloy material, ensuring a balance between visibility and protection. Furthermore, the adjustment assembly includes gears, racks, and slides, all of which are mechanical components used to adjust the baffle's position.

[0044] The reinforcement components include a pump body, rollers, and valve body, which are connected to the valve body by a traction rope. Once attacked, turning the knob will cause the non-Newtonian fluid in the pump body to rush into the cavity inside the shield, thereby rapidly increasing the shield's strength.

[0045] The observation assembly consists of a main tube, observation tube, light intake tube, and lenses. Their specially angled design allows light transmission, enabling the user to safely observe the outside world from behind the shield. The assembly also includes wheels, slots, and levers, which allow it to remain in a fixed position when not in use for storing items such as batons. Attached Figure Description

Detailed Implementation

[0056] Example 1:

[0057] like Figures 1-9 A multi-functional shield, characterized in that it comprises:

[0058] Outer shell 1;

[0059] Adjustment component 2;

[0061] And observation component 4;

[0062] The adjustment component 202 is located in the middle of the housing 1, and the adjustment component 202 includes a window 202 and a baffle 204;

[0063] The reinforcing component 3 is disposed on one side of the housing 1 and extends into the interior of the housing 1;

[0064] The observation component 4 is rotatably mounted on the other side of the outer casing 1;

[0065] By changing the positional relationship between the baffle 204 and the viewing window 202, the reinforcement component 3 is driven to increase the strength of the outer shell 1 and the limiting relationship between the observation component 4 and the outer shell 1. When the shield bearer walks with the shield, the baffle 204 is located inside the outer shell 1 and does not obstruct the view of the viewing window 202. When attacked, the baffle 204 can be rotated to the position of the viewing window 202 to ensure the strength of the shield. At the same time, the reinforcement component 3 is triggered to increase the strength of the shield, and the limiting change between the observation component 4 and the outer shell 1 is also triggered, allowing it to rotate relative to the outer shell 1. This makes it convenient for the person behind the shield to observe the external situation and remove the baton 6, turning it from a container for storing the baton 6 into a tool for convenient observation. This makes the shield bearer lighter when walking, while ensuring the strength of the shield when attacked, and also ensuring that the user's vision is not interfered with by the obstruction of the viewing window 202.

[0066] Specifically, the adjustment component 2 further includes: a knob 201;

[0067] The outer casing 1 is hollow, and the viewing window 202 is located in the middle of the outer casing 1. The knob 201 is rotatably connected to the lower side of the viewing window 202. The knob 201 extends into the interior of the outer casing 1 and is fixedly connected to the baffle 204. The size of the baffle 204 corresponds to the viewing window 202. By rotating the knob 201, the position of the baffle 204 can be made to correspond completely with the viewing window 202.

[0068] Specifically, the viewing window 202 is provided with tempered glass in the hollowed-out area of ​​the outer shell 1, and the baffle 204 is made of alloy material.

[0069] Specifically, the adjustment component 2 further includes:

[0070] Gear 203, rack 205 and slide 206;

[0071] The gear 203 is fixedly disposed in the middle of the connection position between the knob 201 and the baffle 204. The lower side of the gear 203 meshes with the rack 205. The inner wall of the outer casing 1 is provided with the slide 206 that slides with the rack 205.

[0072] Specifically, the enhancement component 3 includes:

[0073] Pump body 301, roller 302, connector 303, pipe 304 and cavity 305;

[0074] The cavity 305 is located in the middle of the interior of the outer shell 1. The insertion interface 303 is located on one side of the outer shell 1 and communicates with the cavity 305. The pump body 301 is an external device. The pump body 301 is connected to the insertion interface 303 through the through pipe 304. The roller 302 is rotatably disposed on the lower side of the pump body 301.

[0075] Specifically, the enhancement component 3 also includes:

[0076] Valve body 306, fixed pulley 307 and traction rope 308;

[0077] The valve body 306 is located at the through-hole position between the insertion port 303 and the cavity 305. One end of the traction rope 308 is located at the end of the rack 205 near the reinforcing component 3, and the other end of the traction rope 308 is connected to the switch of the valve body 306. The fixed pulley 307 is rotatably connected inside the housing 1, and the traction rope 308 is wound around the fixed pulley 307. The pump body 1 contains a high-strength Newtonian fluid. When the shield bearer is attacked and turns the knob 201, the rack 205 moves, causing the traction rope 308 to move along the fixed pulley, triggering the switch of the valve body 306, so that the non-Newtonian fluid inside the pump body 301 rushes into the cavity 305 to increase the shield strength.

[0078] Specifically, the observation component 4 includes:

[0079] Main tube 401, observation tube 402, observation port 405, light inlet tube 407, lens 408, and spring 409;

[0080] The main tube 401 is rotatably disposed on the side of the outer casing 1 away from the reinforcing component 3. The observation tube 402 is disposed below the main tube 401. The light inlet tube 407 is disposed below the main tube 401. The observation tube 405 has an observation port 405. The main tube 401, the observation tube 402 and the light inlet tube 407 are provided with lenses 408 at special angles so that the light source entering through the light inlet tube 407 can be observed through the observation port 405. The lens 408 inside the main tube 401 is connected to the inner wall of the main tube by the spring 409.

[0081] Specifically, the observation component also includes:

[0082] Rotating wheel 403, slot 404, lever 406, vertical bar 410, horizontal bar 411, and inclined block 412;

[0083] The main tube 401 and the outer shell 1 are rotatably connected by the rotating wheel 403, which extends into the interior of the outer shell 1. The lower side of the rotating wheel 403 is provided with the slot 404. The rack 205 is fixedly provided with the crossbar 411 on the side near the observation component 4. The lower side of the crossbar 411 is provided with the inclined block 412. The inner wall of the outer shell 1 near the observation component 4 is provided with the vertical rod 410, which slides up and down. The vertical rod 410 is driven by the inclined block 412. The lower side of the vertical rod 410 is provided with the locking rod 406 that cooperates with the slot 404. An elastic element is provided between the connection position of the vertical rod 410 and the outer shell 1 to keep it in an upward force.

[0084] Specifically, it also includes:

[0085] The baton 6 is inserted into the main tube 401 when the rotating wheel 403 is limited by the locking rod 406. When the baton 6 is inserted into the main tube 401, it compresses the spring 409. When the shield holder is not attacked and is walking with the shield, the vertical rod 410 receives the upward force of the elastic element, causing the locking rod 406 to engage with the locking slot 404, thereby limiting the main tube 401. At this time, the main tube 401 can be used as a container to store the baton 6. The connection between the spring 409 and the lens 408 further facilitates the engagement of the baton 6. When the shield holder is attacked, the knob 201 is turned, and the main tube 401 is disengaged from the outer shell 1. The main tube 401 rotates relative to the outer shell 1 to remove the baton 6. At this time, through the lens set in the main tube 401, the observation tube 402 and the light inlet tube 407, the user can safely observe the external situation behind the shield.

[0086] Specifically, it also includes:

[0087] Handle 5; the handle 5 is fixedly disposed on the inner side of the outer casing 1.

[0088] How to use:

[0089] Walking with the shield: When walking with the shield, the shield is located inside the outer shell and does not obstruct the view, so as to make observation possible; the handle is fixed to the inside of the outer shell, making it convenient for the shield holder to carry; the hollow cavity makes the shield as lightweight as possible, saving the shield holder's physical strength.

[0090] Adjusting the viewing window: Adjust the degree of obstruction of the viewing window by turning the knob. The knob connects to the baffle and the gear. The gear meshes with the rack and pinion, allowing the baffle to slide within the track to adapt to different observation and protection needs.

[0091] Observing the external situation: The observation direction is adjusted by rotating the main tube of the observation component. The lens is placed inside the main tube to ensure that light can be transmitted from the light inlet tube to the observation port, so that the user can safely observe the outside world from behind the shield.

[0092] Enhanced protection when attacked:

[0093] Turn the knob to move the baffle in front of the viewing window to defend against attacks.

[0094] The rotation of the knob simultaneously triggers the valve body of the reinforcement component via the rack and traction rope, causing non-Newtonian fluid to be injected into the cavity, rapidly increasing the shield's strength.

[0095] Rotating the main tube of the observation assembly disengages the lever from the slot, allowing the main tube to rotate relative to the housing for removal of the baton or other operations.

[0096] Retrieve the baton in an emergency: In the event of an attack, the baton stored in the main unit of the observation component can be quickly retrieved for the shield-wielder to counterattack or defend themselves.
