Description

Technical Field

[0001] This utility model relates to the technical field of anti-riot forks, specifically a dust-spraying anti-riot fork. Background Technology

[0002] An explosion-proof fork is a safety device used to deal with emergencies such as danger, violence, or potential explosions. It mainly plays a role in law enforcement and security. It is a long rod-shaped device made of high-strength materials, with a U-shaped or semi-circular fork at one end, designed to effectively control and restrain personnel without causing serious injury.

[0003] In law enforcement scenarios, when law enforcement officers face suspects who are extremely agitated and violently resist law enforcement, relying solely on the physical control of traditional riot control forks is limited in function. Law enforcement officers often need to approach the suspect at close range to exercise control, making it difficult to effectively deter them from a distance. On the other hand, traditional riot control forks do not have fire extinguishing capabilities. In some special law enforcement scenarios, when suspects ignite flammable materials in an attempt to create chaos or obstruct law enforcement, traditional riot control forks cannot extinguish the flames in time and control the spread of the fire. To address these issues, we offer dust-spraying riot control forks. Utility Model Content

[0004] 1) Technical problems to be solved This utility model proposes a dust-spraying anti-riot fork, which solves the problems of existing products having limited functionality, difficulty in effectively deterring enemies from a distance, and lack of fire extinguishing effect by setting up a drive mechanism and plastic hoses and other components.

[0005] (ii) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a dust spray explosion-proof fork, comprising a main rod, one end of which is detachably connected to an explosion-proof fork; a through hole is provided inside the main rod, and a plastic hose is fixedly connected inside the through hole, thereby forming a channel for the flow of medium; a nozzle is fixedly installed on the inner side of the explosion-proof fork for spraying out the medium; a drive mechanism is provided at the end of the main rod away from the explosion-proof fork for injecting the medium into the interior of the plastic hose.

[0006] Furthermore, the end of the explosion-proof fork is provided with two restraint mechanisms to restrain the actions of the rioters.

[0007] Furthermore, the restraint mechanism includes a stop bar, the end of which is fixedly connected to a pin, the outer surface of which is rotatably connected to an explosion-proof fork, and the end of the explosion-proof fork is integrally formed with a protrusion for restricting the stop bar from rotating outward.

[0008] Furthermore, an arc-shaped rod is slidably connected to the inner wall of the explosion-proof fork, and a spring is sleeved on the outer surface of the arc-shaped rod. One end of the spring is fixedly connected to the stop rod, and the other end of the spring is fixedly connected to the explosion-proof fork.

[0009] Furthermore, the drive mechanism includes a dust canister, the upper part of which is detachably connected to a canister opening. A valve is fixedly installed at the upper end of the canister opening, and the end of the valve is detachably connected to the main rod. An air valve is also fixedly installed on the outer surface of the dust canister.

[0010] Furthermore, the driving mechanism includes a fixed rod, the end of which is detachably connected to the main rod, a fixing hoop is fixedly installed on the outer surface of the fixed rod, and a fire extinguisher is fixedly installed inside the fixing hoop.

[0011] Furthermore, a pressure gauge is fixedly installed on the outer surface of the dust can, which is used to detect the air pressure inside the dust can.

[0012] Furthermore, the dust canister has a double-layer structure, comprising an inner layer and an outer layer with a space between them. The inner layer is a plastic layer, and the outer layer is a metal protective shell. The space between the plastic layer and the metal protective shell is filled with heat-insulating material.

[0013] Furthermore, the dust in the dust canister is any one of flour, dry powder, or talcum powder.

[0014] Furthermore, each end of the explosion-proof fork is provided with a detachable explosion-proof rod.

[0015] (iii) Beneficial effects: Compared with existing technologies, this dust-spraying anti-riot fork has the following advantages: I. This dust-spraying riot control fork, through the setting of a drive mechanism and plastic hoses, etc., when remote deterrence is needed, the dust medium enters the plastic hose inside the main rod, and flows rapidly along the hose channel to the nozzle on the inside of the riot control fork. The dust forms a directional jet airflow through the nozzle, precisely acting on the suspect's face or limbs. The irritant effect of the dust forces the suspect to stop resisting, while avoiding serious injury. When a fire occurs, the replaceable drive mechanism allows the fire extinguishing medium to be sprayed in the same directional manner to extinguish the fire. This solves the problems of existing single-function forks that are difficult to effectively deter from a distance and lack fire extinguishing effect.

[0016] II. This dust-spraying riot control fork, through the setting of components such as a stop bar, allows law enforcement officers to approach a suspect with the riot control fork. The suspect's limbs press inward against the stop bar, causing the stop bar to tilt inward around a pivot pin, guiding the limbs smoothly into the fork. Once the limbs are fully inside the fork, the external force disappears, the spring releases its elastic potential energy, and pushes the stop bar to rotate in the opposite direction around the pivot pin to reset. Because the integrally formed protrusion at the end of the riot control fork restricts the stop bar from rotating outward, the reset stop bar will be perpendicular to the inner wall of the fork, preventing the suspect's limbs from escaping outward from the fork, thus achieving the purpose of restraint.

[0020] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-5As shown, this utility model provides a technical solution: a dust spray riot control fork, including a main rod 1, one end of which is detachably connected to a riot control fork 2. A through hole 3 is provided inside the main rod 1, and a plastic hose 4 is fixedly connected inside the through hole 3, thus forming a channel for the flow of media. A nozzle 5 is fixedly installed on the inner side of the riot control fork 2 for spraying media. A drive mechanism 6 is provided at the end of the main rod 1 away from the riot control fork 2, for injecting media into the plastic hose 4. The main rod 1 and the riot control fork 2 are threadedly connected and can be unscrewed. In use, the main rod 1 drives the riot control fork 2 closer to the rioter for physical control. When the rioter cannot approach, the drive mechanism 6 injects media into the plastic hose 4 and then sprays it out at the nozzle 5 to spray at the rioter, facilitating the subjugation of the rioter, or using the appropriate media for on-site fire extinguishing, so as to extinguish the fire as soon as it starts and prevent it from becoming too large.

[0022] The end of the blast fork 2 is equipped with two restraint mechanisms 7, which are used to restrain the movement of rioters. The restraint mechanisms 7 block the rioters, making it difficult for them to break free after entering the blast fork 2.

[0023] The restraint mechanism 7 includes a stop bar 701, with a pin 702 fixedly connected to the end of the stop bar 701. The outer surface of the pin 702 is rotatably connected to the blast fork 2. A protrusion 705 is integrally formed at the end of the blast fork 2 to restrict the stop bar 701 from rotating outward. The stop bar 701 can rotate at a fixed point through the pin 702. When the rioter's legs or other parts are pressed against the stop bar 701 from the outside, the stop bar 701 can rotate and tilt to allow the rioter's body to enter the interior of the blast fork 2. The protrusion 705 is used to prevent the stop bar 701 from rotating outward, so that it can only rotate in the direction of the blast fork 2.

[0024] An arc-shaped rod 703 is slidably connected to the inner wall of the blast fork 2. A spring 704 is sleeved on the outer surface of the arc-shaped rod 703. One end of the spring 704 is fixedly connected to the stop rod 701, and the other end of the spring 704 is fixedly connected to the blast fork 2. When a rioter enters the interior of the blast fork 2, the stop rod 701 is reset under the action of the spring 704, thereby blocking the rioter's body and restricting him to the interior of the blast fork 2.

[0025] Optionally, the ends of the blast-proof fork (2) are respectively provided with detachable blast-proof batons, which can be firmly connected to the fork body through quick disassembly and assembly structures such as threaded connection, snap-on or socket connection. After disassembly, the operator can hold the blast-proof baton to perform a variety of tactical actions: first, it can be used for close-range defense and attack. After the target breaks through the control distance of the long fork, it can effectively block, chop and stab, and realize the offensive and defensive conversion; second, it is suitable for tactical actions in narrow spaces (such as carriages and cabins), solving the problem that long-handled blast-proof forks cannot be used in restricted environments; third, it can be used as an inspection tool to move or move suspicious items and maintain a safe distance. This design significantly improves the tactical flexibility, environmental adaptability and individual combat effectiveness of the equipment, and realizes the comprehensive combat effect of "one fork with multiple functions".

[0026] The drive mechanism 6 includes a dust canister 601. A canister opening 602 is detachably connected to the upper part of the dust canister 601. A valve 603 is fixedly installed at the upper end of the canister opening 602. The end of the valve 603 is detachably connected to the main rod 1. A valve 604 is also fixedly installed on the outer surface of the dust canister 601. In the first embodiment of the drive mechanism 6, the valve 603 is connected to the main rod 1 by bolts. The canister opening 602 is threadedly connected to the dust canister 601. Both can be unscrewed to add dust, such as flour, dry powder, graphite powder, talcum powder, etc., into the dust canister 601. When the dust is flour, it can be sprayed remotely at rioters; when the dust is multi-functional dry powder, it can be used for fire extinguishing. Different types of dust are added depending on the situation. The valve 604 can be pressurized using an air pump. Optionally, a pressure gauge can be installed in the dust canister 601 to detect the pressure value of the dust canister and monitor pressure changes during the inflation process in real time. Operators can precisely adjust valve 603 to stabilize the pressure within the required process range, ensuring product quality, reaction efficiency, and process consistency. During dust loading / unloading, pressurization, and depressurization operations, pressure data provides crucial information for operational decisions. For example, during dust unloading, a pressure drop can indicate whether the material has been emptied, preventing misoperation. When the system malfunctions, pressure readings can quickly distinguish between tank leaks and drive mechanism failures (such as valve jamming), significantly narrowing the troubleshooting scope and saving repair time.

[0027] The drive mechanism 6 includes a fixed rod 605, the end of which is detachably connected to the main rod 1. A fixing hoop 606 is fixedly installed on the outer surface of the fixed rod 605, and a fire extinguisher 607 is fixedly installed inside the fixing hoop 606. As a second embodiment, the fire extinguisher 607 is fixed by the fixing hoop 606. The output head of the fire extinguisher 607 is inserted into the interior of the fixed rod 605. When in use, the sprayed extinguishing medium enters the interior of the plastic hose 4 to facilitate the spraying out of the fire. The drive mechanism 6 can be set to two modes, namely, fire extinguishing or subduing rioters, through a detachable and replaceable method. Where practically permissible, two people can be equipped with each mode.

[0028] The dust canister 601 has a double-layer structure, comprising an inner layer and an outer layer with a space between them. The inner layer is a plastic layer, and the outer layer is a metal protective shell. Insulating material is filled in the space between the plastic layer and the metal protective shell. The outer metal protective shell has greater rigidity and can withstand larger external impacts without easily deforming, and is less likely to cause adverse impacts to the internal sprayed medium. The inner layer is made of plastic, which has a certain degree of deformation capability, thus possessing high pressure resistance. Even if the pressure of the internal dust sprayed medium changes within a certain range, it can be absorbed by the deformation of the plastic layer. The insulating material filling the space between the inner and outer layers effectively isolates the influence of external ambient temperature on the pressure of the internal sprayed medium, improving the structural stability of the dust spray riot control fork and enabling stable use in various harsh outdoor weather environments.

[0029] Working principle: Before use, law enforcement officers can assemble and fix the blast-proof fork 2 to the main rod 1 through a threaded connection. The long rod of the main rod 1 is used to maintain a safe distance. At the same time, the U-shaped fork structure of the blast-proof fork 2 is used to accurately aim at the suspect's legs, torso, and other non-lethal parts. When close to the target, the law enforcement officers push the main rod 1 to make the blast-proof fork 2 fit around the suspect's limbs. The fork body, made of high-strength material, forms an initial physical limit, avoiding the law enforcement risks caused by direct limb contact. This process completely follows the safety control logic of the traditional blast-proof fork 2, ensuring the stability of basic law enforcement functions. The device features a restraint mechanism 7 with a one-way locking function at the end of the explosion-proof fork 2. When law enforcement officers approach a suspect with the explosion-proof fork 2, if the suspect's limbs, such as legs, press against the stop bar 701 inside the fork opening, the stop bar 701 will tilt inwards around the pin 702 as the rotation center, guiding the limbs smoothly into the fork opening. At the same time, it compresses the spring 704 sleeved on the outer surface of the arc-shaped rod 703, converting mechanical energy into the elastic potential energy of the spring 704. When the limbs are fully inside the fork opening, the external force disappears, the spring 704 releases its elastic potential energy, and pushes the stop bar 701 to rotate in the opposite direction around the pin 702 to reset. Because the protrusion 705 integrally formed at the end of the explosion-proof fork 2 restricts the rotation of the stop bar 701 outwards from the fork opening, the reset stop bar 701 will be perpendicular to the inner wall of the fork opening, preventing the suspect's limbs from escaping from the fork opening in the opposite direction, thus achieving the purpose of restraint. In scenarios where it is impossible to approach from a distance or where the suspect resists law enforcement, the first implementation of the drive mechanism 6 allows law enforcement officers to open the valve 603 at the top of the canister 602 when remote deterrence is required. The high-pressure dust medium will enter the plastic hose 4 inside the main rod 1 through the valve 603 and flow rapidly along the hose channel to the nozzle 5 inside the explosion-proof fork 2. Finally, the dust forms a directional jet airflow through the nozzle 5, which is precisely applied to the suspect's face or limbs. The irritant properties of the dust force the suspect to stop resisting, while avoiding serious injury. In response to the special scenario where a suspect ignites flammable materials, the device can be implemented in a second way via the drive mechanism 6. When a fire occurs at the scene, law enforcement officers can directly press the spray switch of the fire extinguisher 607. The extinguishing medium, such as dry powder or carbon dioxide, will enter the plastic hose 4 through the fixed rod 605, be transmitted along the channel to the nozzle 5 of the explosion-proof fork 2, and act on the fire source in a directional spray manner.
