[0002] The stun gun can fire various types of ammunition, including stun rounds, restraint rounds, and pepper spray rounds; among them, restraint rounds are mainly used in situations with low conflict levels and do not cause significant pain to the human body.

[0003] However, the existing restraint rounds are all single-shot restraint rounds. In operation, if a single restraint round misses the target or goes astray after being fired, it is easy to fail to solve the actual problem.

[0004] Therefore, there is an urgent need to provide a multi-constrained projectile structure capable of continuous firing. Summary of the Invention

The rear end of the excitation tube is installed in the corresponding excitation channel, and the flying needle assembly is disposed in the corresponding excitation tube.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] The purpose of this invention is to provide a structure for continuously firing multiple restraint projectiles and a riot control device to solve the problems existing in the prior art, thereby enabling the continuous firing of multiple restraint projectiles and improving the riot control effect.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figures 1-4 As shown, this embodiment provides a continuously firing multi-constraint projectile structure, mainly including: a main shell 1, and: constrained projectiles, primers 5, and conductive components installed inside the main shell 1; wherein, the rear end of the main shell 1 can be installed on the main body of the riot control device, and the front end of the main shell 1 is provided with multiple firing channels; the constrained projectiles correspond one-to-one with the firing channels, and each firing channel is equipped with one constrained projectile; the primers 5 correspond one-to-one with the constrained projectiles, and each constrained projectile has a primer 5 at its rear end, which can fire the corresponding constrained projectile, and the primer 5 is provided with an arc trigger point; the minimum distance from the arc trigger point on the primer 5 to the conductive component is the firing distance of the primer 5, and the firing distances of any two primers 5 are different. When the conductive component is energized, the primers 5 can be fired sequentially in order of increasing firing distance, thereby firing each constrained projectile sequentially, realizing the continuous firing of multiple constrained projectiles, avoiding the risk of a single constrained projectile missing the target, and improving the riot control effect.

[0035] It should be noted that when the conductive component is energized, it is electrically connected to one of the positive or negative terminals of the power supply, while the primer 5 is electrically connected to the other terminal of the power supply. After the power supply is connected, an electric arc can be generated between the arc trigger point on the primer 5 and the conductive component, thereby activating the primer 5. All primers 5 are activated sequentially in order of increasing activation distance, thereby achieving continuous activation of the constrained projectile.

[0036] It should be further explained that in this embodiment, "rear end" refers to the end closest to the main body of the riot control device after the continuously activated multi-constraint projectile structure is installed on the main body of the riot control device, while "front end" is the other end opposite to "rear end".

[0037] In this embodiment, an opening is provided at the front end of the main housing 1, and a projectile cover 2 is provided at the opening. The projectile cover 2 can be fixed to the main housing 1 by snap-fit ​​or other means, which can prevent the restrained projectile from being exposed, improve the aesthetic effect, and prevent dust from entering the main housing 1. Moreover, some markings can be added to the projectile cover 2 later to achieve publicity or warning effects. It should be noted that when the restrained projectile is fired, it can break through the corresponding projectile cover 2 and thus be fired out from the main housing 1.

[0038] In this embodiment, each of the restraint projectiles preferably includes two flying needle assemblies 3, the rear ends of which are connected by a connecting rope. When the restraint projectile is activated, the rear ends of the two flying needle assemblies 3, along with the connecting rope, fly out together. When the connecting rope acts on the target, due to the force, the two flying needle assemblies 3 respectively drive the two ends of the connecting rope to begin wrapping around the target. After wrapping, the flying needle assemblies 3 hook onto the target, ultimately achieving the restraint purpose. It should be noted that the above-described working principle of the restraint projectile is a mature existing technology in the field and will not be described in detail in this embodiment. It should be noted that the front ends of the two flying needle assemblies 3 should be far apart from each other to form an angle between them, which facilitates the restraint of the target.

[0039] In this embodiment, the constrained projectile may also be equipped with other numbers of flying needle components 3 according to specific working needs, such as four or six flying needle components 3, as long as the rear ends of all flying needle components 3 are connected by connecting ropes and can achieve the constraint of the target.

[0040] In this embodiment, the number of restraining projectiles can be selected according to specific operational needs, preferably two, or three or four restraining projectiles can also be set.

[0041] In this embodiment, each of the excitation channels includes two sub-channels, and each sub-channel is configured in a one-to-one correspondence with a flying needle assembly 3. The two flying needle assemblies 3 of the constrained projectile are respectively installed in the two sub-channels. The rear openings of the two sub-channels are located close to the primer 5. When the primer 5 corresponding to the constrained projectile is excited, the released energy can be transmitted along the two sub-channels to the flying needle assembly 3 therein to excite the flying needle assembly 3.

[0042] As a preferred embodiment, in this embodiment, such as Figure 4 As shown, the two sub-channels form a V-shaped excitation channel, and the two flying needle assemblies 3 of the same constrained projectile are also arranged in a V-shape, and the included angle between the two flying needle assemblies 3 is preferably an acute angle.

[0043] In this embodiment, the flying needle assembly 3 includes a flying needle 301 and a syringe 303. The flying needle 301 is mounted on the front end of the syringe 303, and the rear end of the syringe 303 is connected to the connecting rope. Specifically, the syringe 303 can fix the flying needle 301. The flying needle 301 can be installed on the front end of the syringe 303 by welding or bonding. The rear ends of the two syringes 303 are respectively connected to the two ends of the connecting rope.

[0044] In this embodiment, the flying needle 301 is preferably a multi-claw flying needle. After various tests, the multi-claw flying needle is more likely to grip the target object, and the tip of the multi-claw flying needle has barbs to prevent it from falling off after hooking the target; more preferably, the flying needle 301 is a four-claw flying needle.

[0045] In this embodiment, the continuously excited multi-constraint projectile structure further includes an excitation tube 302, which corresponds one-to-one with the flying needle assembly 3. The rear end of the excitation tube 302 is installed in the sub-channel of the corresponding excitation channel, and the flying needle assembly 3 is disposed in the corresponding excitation tube 302. Each sub-channel has one excitation tube 302 installed. When the primer 5 corresponding to the flying needle assembly 3 is excited, the released energy can drive the flying needle assembly 3 to move from back to front along the excitation tube 302 to achieve the excitation of the flying needle assembly 3.

[0046] In this embodiment, the excitation tube 302 is a metal tube, preferably an aluminum tube. The rear end of the excitation tube 302 can be assembled into the main housing 1 by means of snap-fit ​​or welding to prevent the excitation tube 302 from moving when the constrained projectile is excited, thereby improving the connection between the excitation tube 302 and the main housing 1. Moreover, the front end of the excitation tube 302 extends out of the corresponding sub-channel, and the connecting rope can be wrapped around the outer wall of the front end of the excitation tube 302 to increase the winding space.

[0047] In this embodiment, a primer ignition cavity 4 is provided inside the main housing 1. The front end of the primer ignition cavity 4 is provided with a V-shaped ignition channel, and the rear end is provided with a primer channel. The primer channel and the ignition channel correspond one-to-one, and the rear end of the ignition channel is connected to the corresponding primer channel to form a Y-shaped cavity. The primer 5 is installed in the primer channel. When the primer 5 is ignited, it can release energy along the V-shaped ignition channel to ignite the flying needle assembly 3, and the primer 5 can move backward along the primer channel.

[0048] In this embodiment, the primer ignition cavity 4 is preferably a metal cavity, which improves the overall strength and can better absorb the energy released when the primer 5 is ignited.

[0049] In this embodiment, a conductive part is provided at the rear end of the primer 5, and the rear end face of the conductive part forms the arc trigger point. The sidewall of the conductive part is insulated (with an external insulating layer such as insulating tape or an insulating coating, etc.). Preferably, the conductive part is cylindrical, and its diameter is smaller than that of the primer 5. A cavity cover 6 is provided at the rear end of the primer ignition cavity 4. The cavity cover 6 has a through hole, which allows the conductive part to pass through and blocks the primer 5 from passing through, thereby resisting the recoil of the primer 5 and the energy released backward after the primer 5 is ignited. The cavity cover 6 is also preferably made of metal.

[0050] In this embodiment, the conductive component is preferably a conductive spring 8. A base 7 is also provided inside the main housing 1. The base 7 is located at the rear end of the primer ignition cavity 4, and the conductive spring 8 is disposed inside the base 7. The conductive spring 8 is provided with a plurality of through holes, and the through holes correspond one-to-one with the primer 5. When the primer 5 is ignited, the arc trigger point on the primer 5 can pass through the corresponding through hole. At this time, the insulating position on the conductive part sidewall (with threads) is located in the through hole of the conductive spring 8, while the arc trigger point is away from the conductive spring 8 to prevent re-ignition and ensure that the next ignition is of another primer 5.

[0051] In this embodiment, since the primer ignition cavity 4 is a metal cavity, the primer 5 can be connected to one of the positive or negative poles of the power supply through the metal cavity, and the conductive spring 8 can be connected to the other pole of the power supply, and the metal cavity and the conductive spring 8 are insulated from each other.

[0052] As a preferred implementation method, such as Figure 3 As shown, a positive interface 10 is provided on one side of the main housing 1. The primer ignition chamber 4 is electrically connected to the positive terminal of the power supply through the positive interface 10. After the positive current is input, it passes through the primer ignition chamber 4, the primer 5, and the conductive part in sequence, and then reaches the vicinity of the conductive spring 8. On the other side of the main housing 1, a negative interface 11 is provided. The negative interface 11 is arranged opposite to the positive interface 10 and can be electrically connected to the negative terminal of the power supply. The negative interface 11 is electrically connected to the conductive spring 8 through a conductive element (copper foil or copper wire, etc.). When the negative current is input, it is transmitted to the conductive spring 8 through the conductive element.

[0053] In this embodiment, an insulating sheet 9 is provided between the primer ignition cavity 4 and the conductive component for insulation, and an insulating sheet 9 is also provided between the end of the conductive spring 8 away from the conductive component and the inner wall of the main housing 1 for insulation.

[0054] The working principle of the continuously excited multi-constraint elastic structure in this embodiment is as follows:

[0055] When the continuously activated multi-constraint projectile structure is installed on the main body of the riot control device, the main body of the riot control device provides high-voltage current to the two constrained projectile bodies; such as Figure 3As shown, the positive current passes sequentially through the primer ignition cavity 4, primer 5, and conductive part, and then reaches the vicinity of the conductive spring 8; while the negative current passes through the conductive part and is transmitted to the conductive spring 8. Since the minimum distance from the arc trigger point of the primer 5 of the two constraint bodies to the conductive spring 8 is different (the ignition distance of the lower primer 5 is less than that of the upper primer 5), when there is a high voltage current, the lower primer 5 is ignited first. Due to the recoil, the primer 5 will shift in the opposite direction of ignition after ignition. After shifting, the part of the primer 5 located in the through hole of the conductive spring 8 is the insulating position on the side wall of the conductive part, and the distance from the arc trigger point to the conductive spring 8 becomes farther. At this time, the distance from the arc trigger point on the upper primer 5 to the conductive spring 8 is closer. Therefore, after power is supplied again, the upper primer 5 is ignited first.

[0056] After primer 5 is ignited, as Figure 4 As shown, the generated energy acts on the two corresponding syringes 303, which are at an acute angle. The powerful energy propels the syringes 303, along with the flying needle 301, to break through the projectile cover 2 and propel them out. When the flying needle 301 flies out, the tail of the syringe 303, along with the connecting rope, also flies out. When the connecting rope acts on the target, due to the force, both ends of the connecting rope begin to wrap around the target, and then the flying needle 301 hooks onto the target, ultimately achieving the restraint purpose.
