Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of riot control, and particularly relates to a hand-throwing type riot control device for aerodynamic release of riot control agents. BACKGROUND

[0002] Group events can seriously affect the social stability of an area. Stimulant riot control equipment is important equipment for handling the above-mentioned events, and through the principles of smoke generation, explosion, and air pressure, the riot control agents are dispersed in the air, so that the target crowd feels burning and pain on the skin and nose, and the eyes are irritated and tearful, so as to disperse the target crowd. Common riot control agents include o-chlorobenzalmalonitrile (CS) and capsaicin (OC), and according to the release principle of the riot control agent, the equipment can be divided into smoke type equipment, explosive type equipment, and air pressure dispersion equipment.

[0003] The smoke type equipment mainly vaporizes the irritating agent in it to form smoke through the heat generated by combustion, and the representative equipment is smoke type tear gas ammunition; the explosive type equipment mainly releases the irritating agent in it to form smoke through the explosion of explosives, and the representative equipment is explosive type tear gas ammunition; the air pressure dispersion equipment mainly sprays the irritating agent solution in it directly through the pressing force, and the representative equipment is a hand-held anti-wolf spray.

[0004] The current air pressure dispersion equipment mainly sprays the irritating agent solution through the pressing force of the fingers, and the action distance is relatively short, about 5-8 meters. Therefore, a hand-throwing type riot control device for aerodynamic release of riot control agents is needed to increase the action distance, act on a distance of 20-40 meters, release the torque through the pressure at one end to make the device rotate, form a rotating spraying state, increase the action range, and have the function of anti-throwing. SUMMARY

[0005] (I) Technical problem to be solved

[0006] The application provides a hand-throwing type riot control device for aerodynamic release of riot control agents to solve the technical problem of safety hazards of related department personnel in riot control operations due to the short action distance of the hand-held pressing type spraying device.

[0007] (II) Technical scheme

[0008] In order to solve the above technical problem, the application provides a hand-throwing type riot control device for aerodynamic release of riot control agents, which comprises a container shell, a constant-pressure compression spring, a piston plate, a container outer cover, a cover body sealing ring, a one-way liquid inlet valve, a container inner cover, a handle, a split pin, a safety pin, a pressure rod, a compression spring, a screw, a fluid channel, and a riot control agent solution; wherein,

[0009] The container shell is divided into upper and lower spaces by a piston plate. The explosion control agent solution is filled into the upper space under certain pressure. A pressure-stabilizing compression spring is installed in the lower space of the container shell, which is normally kept compressed and at the same pressure as the explosion control agent solution. When the explosion control agent solution is released, as the pressure in the upper space decreases, the pressure on the pressure-stabilizing compression spring decreases, allowing the spring to rebound upwards. This pushes the piston plate to move, slowing down the pressure decay in the container shell and allowing the explosion control agent solution to be fully released. The outer cap is installed on the top of the container shell and sealed by a cap sealing ring. A one-way inlet valve is installed on the outer cap for pressurizing the explosion control agent solution into the container shell. The inner cap is installed in the central threaded hole of the outer cap via external threads.

[0010] A handle is installed on the inner lid of the container. A safety pin passes through the lug of the handle and the inner lid of the container to fix the handle to the inner lid of the container. Before throwing, the safety pin is pulled out to release the safety, so that the handle can rotate around the support axis on the inner lid of the container. The inner lid of the container is provided with an arc-shaped slide. A cotter pin passes through the lug of the handle and the inner lid of the container and can slide to the end position in the slide to limit the rotation angle of the handle.

[0011] The inner lid of the container has a central hole and an L-shaped liquid flow channel. The top of the central hole is located on the upper surface of the inner lid, and the bottom of the central hole is connected to the bend of the liquid flow channel. The vertical channel of the liquid flow channel is connected to the explosion control agent solution, and the horizontal channel of the liquid flow channel is connected to the atomizing nozzle through the side wall of the inner lid. A compression spring is fitted onto the pressure rod and installed on the top of the central hole of the inner lid. Under the action of the compression spring, the rear end face of the pressure rod facing outward abuts against the top of the handle, and the front end face abuts against the bend of the liquid flow channel. When the handle is not released, the front end face of the pressure rod prevents the explosion control agent solution from flowing out from the horizontal channel of the liquid flow channel.

[0012] Furthermore, two O-rings are provided on the outer periphery of the piston plate.

[0013] Furthermore, the outer lid of the container is attached to the top of the container shell by screws.

[0014] Furthermore, the connection between the inner lid and the outer lid of the container is a raised shoulder structure.

[0015] Furthermore, the shoulder area is sealed using a sealing ring between the covers.

[0016] Furthermore, two pressure bar sealing rings are provided at the front end of the pressure bar to prevent leakage of the explosion control agent solution.

[0017] (III) Beneficial Effects

[0018] This invention proposes a pneumatically operated, hand-thrown riot control device for dispensing riot control agents. The device includes a container shell, a pressure-stabilizing compression spring, a piston plate, an outer container cover, a cover sealing ring, a one-way liquid inlet valve, an inner container cover, a handle, a cotter pin, a safety pin, a pressure rod, a compression spring, a screw, a fluid channel, and a riot control agent solution. After being thrown, the pressure rod rises under the pressure inside the container shell, causing the handle to rotate around a support shaft on the inner container cover. The cotter pin slides to its termination position within an arc-shaped track, restricting the rotation of the handle and thus limiting the upward distance of the pressure rod. The rising pressure rod opens the liquid channel, allowing the riot control agent solution to flow through it under internal pressure and be sprayed into the external environment through an atomizing nozzle connected to the end of the channel. During spraying, because the force at one end of the device is not at the same point as the center of mass, the device rotates rapidly, thus providing anti-reverse-throw functionality. This device is applicable to situations such as handling mass incidents. This invention enriches the range of devices used in riot control operations, providing diverse options for such actions. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the hand-thrown riot control device of the present invention;

[0020] Figure 2 This is an enlarged view of the top structure of the hand-thrown riot control device of the present invention. Detailed Implementation

[0021] To make the objectives, contents, and advantages of the present invention clearer, the specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0022] This embodiment proposes a hand-operated riot control device for pneumatically releasing riot control agents, the structure of which is as follows: Figure 1 As shown, it mainly includes a container shell 1, a pressure-stabilizing compression spring 2, an O-ring seal 3, a piston plate 4, an outer container cover 5, a cover seal 6, a one-way inlet valve 7, a cover seal 8, an inner container cover 9, a handle 10, a cotter pin 11, a safety pin 12, a pressure rod 13, a compression spring 14, a screw 15, a pressure rod seal 16, a fluid channel 17, and a storm control agent solution 18.

[0023] The interior of the container shell 1 is divided into upper and lower spaces by a piston plate 4. The explosion control agent solution 18 is filled into the upper space under certain pressure. Two O-rings 3 are provided on the outer periphery of the piston plate 4 to prevent the explosion control agent solution 18 from flowing into the lower space of the container shell 1. A pressure-stabilizing compression spring 2 is installed in the lower space of the container shell 1. Normally, it is kept compressed, matching the pressure of the explosion control agent solution 18. When the explosion control agent solution 18 is released, as the pressure in the upper space decreases, the pressure on the pressure-stabilizing compression spring 2 decreases, allowing it to rebound upwards. This pushes the piston plate 4 to move, slowing down the pressure decay in the container shell 1 and allowing the explosion control agent solution 18 to be fully released. The outer cover 5 is installed on the top of the container shell 1 by screws 15 and sealed by a cover sealing ring 6.

[0024] The outer cover 5 of the container is equipped with a one-way inlet valve 7 for pressurizing and filling the explosion control agent solution 18 into the container shell 1. The inner cover 9 of the container is installed in the central threaded hole of the outer cover 5 via external threads. The connection between the inner cover 9 and the outer cover 5 is a shoulder structure, and the shoulder is sealed by the inter-cover sealing ring 8.

[0025] like Figure 2 As shown, a handle 10 is mounted on the inner lid 9 of the container. A safety pin 12 passes through the lug of the handle 10 and the inner lid 9 of the container to secure the handle 10 to the inner lid 9. Before throwing, the safety pin 12 is pulled out to release the safety, allowing the handle 10 to rotate around the support axis on the inner lid 9. The inner lid 9 of the container is provided with an arc-shaped slide 20. A cotter pin 11 passes through the lug of the handle 10 and the inner lid 9 of the container and can slide within the slide 20 to the termination position 11' to limit the rotation angle of the handle 10.

[0026] The inner lid 9 of the container has a central hole and an L-shaped liquid flow channel 17. The top of the central hole is located on the upper surface of the inner lid 9, and the bottom end communicates with the bend of the liquid flow channel 17. The vertical channel of the liquid flow channel 17 communicates with the explosion control agent solution 18, and the horizontal channel of the liquid flow channel 17 extends from the side wall of the inner lid 9 to the outside and connects to the atomizing nozzle 19. A compression spring 14 is fitted onto the pressure rod 13 and installed on top of the central hole of the inner lid 9. Under the action of the compression spring 14, the rear end face of the pressure rod 13 facing outward abuts against the top of the handle 10, and the front end face abuts against the bend of the liquid flow channel 17. When the handle 10 is not released, the front end face of the pressure rod 13 prevents the explosion control agent solution 18 from flowing out of the horizontal channel of the liquid flow channel 17. Two pressure rod sealing rings 16 are provided at the front end of the pressure rod 13 to prevent leakage of the explosion control agent solution 18.

[0027] The device is used as follows: Hold the handle 10 and the container shell 1, pull out the safety pin 12, and throw the device. Under the pressure inside the container shell 1, the pressure rod 13 rises, causing the handle 10 to rotate around the support shaft on the inner cover 9 of the container. The cotter pin 11 slides to its stop position within the arc-shaped slide 20, restricting the rotation of the handle 10 and thus limiting the rising distance of the pressure rod 13. After the pressure rod 13 rises, the liquid flow channel 17 opens, and the explosion control agent solution 18 flows through the liquid flow channel 17 under internal pressure and is sprayed into the external environment through the atomizing nozzle 19 connected to the end of the liquid flow channel 17. During spraying, because the force at one end of the device is not at the same point as the center of mass, the device rotates rapidly, thus providing an anti-reverse-throw function.

[0028] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
