Description

Technical Field

[0001] This invention relates to the field of police equipment technology, and in particular to a continuous firing structure and firing device controlled by an insulating block. Background Technology

[0002] A primer is a pyrotechnic device installed at the bottom of a cartridge case, ignited by the input of mechanical or electrical energy, used to output a flame to ignite the propellant. When an electric primer is used to ignite, it can typically fire only one bullet at a time, and cannot achieve continuous fire. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous firing structure and firing device controlled by an insulating block, which can achieve continuous firing when the primer is fired with electrical energy.

[0004] To achieve the above objectives, the present invention provides the following solution:

[0005] This invention discloses a continuous firing structure controlled by an insulating block for mounting on a riot control device, comprising:

[0006] The housing assembly includes an insulating housing, a front cover, and a rear cover, the front cover and the rear cover being fixed to the front end and rear end of the insulating housing, respectively; the front cover is made of metal and is used to connect to one of the discharge electrodes of the riot control device.

[0007] A metal pressure-bearing tube is fixed inside the insulating shell, and the metal pressure-bearing tube is used to load riot control bullets; the front cover is provided with a first through hole that is directly opposite the front end of the metal pressure-bearing tube, and the front cover is electrically connected to the metal pressure-bearing tube;

[0008] A discharge electrode fixed inside the insulating shell includes an electrode body and multiple bends, each bend including a connecting section and a discharge section; the front end of the connecting section is perpendicularly fixed to the discharge section, and the rear end of the connecting section is perpendicularly fixed to the electrode body; the length direction of the connecting section is parallel to the front-back direction; the electrode body is used to connect to another discharge electrode of the riot control device.

[0009] Multiple primer assemblies are slidably installed within the insulating housing. Each primer assembly includes a primer and an insulating block located behind the primer. A metal pressure-bearing tube is provided on the front side of each primer, and a discharge segment abuts against the rear side of each insulating block. A second through-hole is provided on the insulating block in the front-rear direction, allowing the discharge arc between the discharge segment and the primer to pass through. The length of the second through-hole is the distance between the discharge segment and the primer, and the length of the second through-hole corresponding to each insulating block is different. The insulating block is used to break or bend the corresponding discharge segment backward when its corresponding primer is fired, thereby increasing the discharge distance of the discharge arc and enabling multiple primers to fire continuously.

[0010] Preferably, the electrode body is a strip-shaped plate electrode.

[0011] Preferably, there are four bending portions, and there are also four metal pressure-bearing pipes, four primers, and four insulating blocks.

[0012] Preferably, the discharge electrode further includes a lead strip, the first end of which is connected to the electrode body, and the second end of which is used to connect to one of the discharge electrodes of the riot control device.

[0013] Preferably, in the front-to-back direction, each primer is equidistant from the electrode body.

[0014] Preferably, the first through hole has a contraction structure, with the front diameter of the first through hole being smaller than the rear diameter, so that the riot control projectile breaks upon impact with the inner wall of the first through hole, and the internal filling material of the riot control projectile is released outward through the first through hole.

[0015] Preferably, the bent portion is a copper sheet metal part with a thickness of less than 0.5 mm.

[0016] The present invention also discloses a launching device, including the above-mentioned continuous firing structure controlled by the insulating block and the riot suppressor, wherein the front cover and the electrode body are respectively used for electrical connection with the two poles of the riot suppressor.

[0017] The present invention achieves the following technical effects compared to the prior art:

[0018] When the discharge electrode discharges between the primer and the discharge electrode, the current automatically selects to pass through the shortest second through hole. When the primer corresponding to the shortest second through hole is fired, the insulating block containing that through hole slides backward under the recoil force of the primer, breaking or bending the discharge segment corresponding to that insulating block, thus increasing the discharge path of that segment to a length greater than any second through hole. At this point, the discharge arc selects to pass through a second through hole on another insulating block, igniting the primer corresponding to that through hole and firing the corresponding riot control projectile. This process continues until all primers are fired and all riot control projectiles are fired, at which point the continuous firing process of the riot control projectiles ends. Therefore, this invention enables continuous firing of riot control projectiles, avoiding the danger of missing a projectile when selecting single-shot mode. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] The purpose of this invention is to provide a continuous firing structure and firing device controlled by an insulating block, which can achieve continuous firing when the primer is fired with electrical energy.

[0027] 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. In this embodiment, the riot suppressor refers to an stun gun.

[0028] Reference Figures 1-4 This embodiment provides a continuous firing structure controlled by an insulating block for installation on a riot control device, including a housing assembly, a metal pressure-bearing tube 3, a discharge electrode 4, and a primer assembly.

[0029] The outer casing assembly includes an insulating outer casing 1, a front cover 2, and a rear cover (not shown in the figure). The front cover 2 and the rear cover are fixed to the front and rear ends of the insulating outer casing 1, respectively. The front cover 2 is made of metal and is used to connect to one of the discharge electrodes of the riot control device. A metal pressure-bearing tube 3 is fixed inside the insulating outer casing 1 and is used to load riot control ammunition. The front cover 2 has a first through hole 21 that is directly opposite the front end of the metal pressure-bearing tube 3, and the front cover 2 is electrically connected to the metal pressure-bearing tube 3. The discharge electrode 4 is fixed inside the insulating outer casing 1 and includes an electrode body 41 and multiple bends. Each bend includes a connecting section 43 and a discharge section 42. The front end of the connecting section 43 is perpendicular to and fixedly connected to the discharge section 42, and the rear end of the connecting section 43 is perpendicular to and fixedly connected to the electrode body 41. The length of the connecting section 43 is horizontal. The electrode body 41 is used to connect with another discharge electrode of the riot control device. Multiple primer assemblies are slidably installed in the insulating shell 1. Each primer assembly includes a primer 5 and an insulating block 6 located behind the primer 5. A metal pressure-bearing tube 3 is provided on the front side of each primer 5, and a discharge section 42 is abutted on the rear side of each insulating block 6. A second through hole 61 is provided on the insulating block 6 along the front-back direction. The second through hole 61 allows the discharge arc between the discharge section 42 and the primer 5 to pass through. The length of the second through hole 61 is the distance between the discharge section 42 and the primer 5. The length of the second through hole 61 corresponding to each insulating block 6 is different. The insulating block 6 is used to break or bend the corresponding discharge section 42 when the primer 5 is fired, so as to increase the discharge distance of the discharge arc and enable multiple primers 5 to be fired continuously.

[0030] The working principle of this continuous firing mechanism is as follows:

[0031] After the front cover 2 and electrode body 41 are electrically connected to the two poles of the riot control device, pulling the activation lever of the riot control device causes the discharge arc output by the riot control device to pass through the second through hole 61 and ignite the primer 5, igniting the propellant in the primer 5, causing the riot control projectile to be fired from the first through hole 21. The front cover 2, metal pressure-bearing tube 3, primer 5, and discharge electrode 4 are connected in series to realize the flow of current in the continuous firing structure. When the discharge electrode 4 discharges between the primer 5, the current will automatically choose the path of least resistance. When the discharge arc breaks through the air, the shorter the path it travels, the lower the corresponding resistance. Therefore, when the discharge electrode 4 discharges between the primer 5, the current will automatically choose to pass through the second through hole 61, which has the shortest length. When the primer 5 corresponding to the shortest second through-hole 61 is fired, the insulating block 6 containing the second through-hole 61 slides backward under the recoil force generated by the primer 5, breaking or bending the discharge segment 42 corresponding to the insulating block 6, thus increasing the discharge path of the discharge segment 42 to be greater than the length of any second through-hole 61 (the discharge path changes from a straight line to a broken line). At this time, the discharge arc chooses to pass through the second through-hole 61 on another insulating block 6 (the second shortest second through-hole 61), causing the primer 5 corresponding to the second through-hole 61 to be fired, and the corresponding riot control projectile is launched. This process continues until all primers 5 are fired and all riot control projectiles are launched, at which point the continuous firing process of the riot control projectiles ends.

[0032] Reference Figure 2 As one possible example, the electrode body 41 is a strip-shaped plate electrode. Depending on the actual needs, those skilled in the art may also choose other shapes of electrode bodies 41, such as circular plate electrodes.

[0033] Reference Figure 2 As a possible example, there are four bends, and there are also four metal pressure pipes 3, four primers 5, and four insulating blocks 6.

[0034] Reference Figure 2 As a possible example, in order to facilitate the connection of the electrode body 41 to the discharge electrode of the riot control device, the discharge electrode 4 also includes a lead bar 44, the first end of which is connected to the electrode body 41, and the second end of which is used to connect to one of the discharge electrodes of the riot control device.

[0035] Reference Figure 2 , Figure 3 Since the length of the connecting segment 43 has little effect on the discharge resistance, as a possible example, each primer 5 is equidistant from the electrode body 41 in the front-to-back direction, meaning the lengths of the connecting segments 43 are different. Depending on the actual needs, those skilled in the art may also make each connecting segment 43 the same length.

[0036] Reference Figure 1As one possible example, the first through-hole 21 has a constricted structure, with the front diameter of the first through-hole 21 being smaller than the rear diameter. This allows the riot control projectile to break upon impact with the inner wall of the first through-hole 21, releasing the internal filling material through the first through-hole 21. After the primer 5 is fired, the riot control projectile slides forward within the metal pressure-bearing tube 3 and impacts the inner wall of the first through-hole 21. Upon impact, the outer shell of the riot control projectile breaks, and the pepper powder, pepper liquid, or other filling material inside the riot control projectile is released outward through the first through-hole 21, achieving the purpose of riot control. It should be noted that in this example, the riot control projectile should be a riot control projectile with internal powder or liquid filling material, such as a tear gas projectile. Depending on the actual needs, those skilled in the art may also choose a first through-hole 21 with a uniform cross-section, allowing a solid riot control projectile (e.g., a rubber bullet) to pass directly through the first through-hole 21.

[0037] As one possible example, the insulating shell 1 is made of plastic. The insulating shell 1 can be used by the user to hold the device or to connect it to other external structures to prevent electric shock. Depending on the specific needs, those skilled in the art may also choose other commonly used insulating materials.

[0038] As a possible example, in order to ensure that the insulating block 6 can break or bend its corresponding discharge tip 52, the thickness of the discharge tip should be reasonably selected. The bending part is a copper sheet metal part with a thickness of less than 0.5 mm, and preferably 0.2 mm.

[0039] This embodiment also provides a launching device, including the aforementioned continuous firing structure controlled by an insulating block and a riot control device. The front cover 2 and the electrode body 41 are respectively used for electrical connection with the two poles of the riot control device. This launching device can also be called a riot control device or a police riot control device; since this launching device has the aforementioned continuous firing structure, it also has the corresponding technical effects of the continuous firing structure, which will not be elaborated here.

[0040] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
