Description

Technical Field

[0001] This invention relates to the field of firearm structure technology, and in particular to a double-click firing mechanism suitable for a double-chamber riot gun. Background Technology

[0002] Dual-chamber riot guns allow for controlled lethality. Depending on the environment and target, the shooter can flexibly adjust the muzzle velocity of the projectile to regulate the terminal impact kinetic energy and achieve the desired effect. Traditional firearms typically use mechanical ignition, while electric ignition, limited by structural size and complexity, is often used in artillery. However, dual-chamber riot guns require strict control of ignition timing to ensure simultaneous firing of both chambers. Therefore, electric ignition is chosen to guarantee consistent firing delay. Furthermore, due to the dual-prime, dual-circuit design of dual-chamber ammunition, a double-pin firing mechanism is needed to meet the shooter's firing selection requirements when using dual-chamber ammunition, reliably and rapidly transmit the firing signal, and maintain a compact size to meet basic firearm design requirements. Summary of the Invention

[0003] In view of the above-mentioned problems existing in the prior art, the present invention provides a double-click firing mechanism suitable for dual-chamber riot guns, for non-lethal firearm structural design. The firing circuit of the double-click firing mechanism is optional and can meet the usage requirements of dual-chamber riot guns; it has a simple and compact structure; reliable insulation and high safety; it uses a spring as the energy for firing pin extension and retraction, ensuring reliable operation and strong environmental adaptability.

[0004] This invention provides a double-click firing mechanism for a dual-chamber riot gun, the method comprising:

[0005] The firing pin assembly includes two firing pins, a firing pin insulating assembly located between the two firing pins for isolation, two firing pin springs respectively sleeved on the firing pins and pushing against the firing pins to keep the firing pins in contact with the bottom of the ammunition, and a firing pin plug for sealing the firing pin insulating assembly.

[0006] A conductive rod assembly includes two conductive rods, a conductive rod insulating assembly located between the two conductive rods for isolation, two conductive rod springs respectively sleeved on the conductive rods and pushing against the conductive rods to keep the conductive rods and conductive blocks in a continuous state, and a conductive rod plug for sealing the conductive rod insulating assembly.

[0007] The firing mode selection component includes a main body, a knob installed in the main body and capable of rotating to change the firing mode, four ejector pin assemblies installed inside the knob, four conductive plates fixed at the input and output interfaces of the main body respectively, thin wires connected to the outside of the conductive plates, and the inside of the conductive plates connected to the ejector pin assemblies, with the tails of two ejector pin assemblies with the same path connected. By rotating the knob, different firing modes are selected.

[0008] During feeding, firing, and ejection, when the bolt is in the rear-hook position, the firing pin protrudes from the cartridge base under the action of the firing pin spring, and the conductive rod retracts under the pressure of the receiver. After the bolt pushes the cartridge into the chamber and completes the locking, the firing pin is pressed back into the bolt by the bottom surface of the cartridge, and the conductive rod connects with the conductive plate on the receiver under the action of the conductive rod spring, completing the conduction of the entire circuit. When the bolt unlocks and moves rearward to extract the cartridge, the conductive rod retracts immediately under the pressure of the receiver, and the firing pin extends after ejection, cutting off the circuit.

[0009] In some embodiments of the present invention, the firing position selection component provides three position selections. When the knob is rotated to a fixed position, the ejector pin assembly protrudes to conduct the circuit. When the knob is in other positions, the circuit is disconnected.

[0010] In some embodiments of the present invention, the firing pin, the conductive rod, and the two pins in the same path as the firing position selection component are all connected by wire welding with a margin to ensure reliable conduction when the mechanism is in operation.

[0011] In some embodiments of the present invention, the firing pin assembly and the lower half of the conductive rod assembly are installed inside the bolt and reciprocate with the bolt, and the upper half of the conductive rod assembly and the firing position selection assembly are fixedly installed on the receiver.

[0012] When the bolt is in the locked position, the upper and lower halves of the conductive rod assembly are in contact, and the firing mechanism is activated. When the bolt is in any other position, the firing mechanism is deactivated.

[0013] In some embodiments of the present invention, the ejector pin assembly includes an ejector pin head, an ejector pin body, and an ejector pin spring. After the ejector pin head presses the ejector pin spring into the ejector pin body, the movement space of the ejector pin head is restricted around the ejector pin body using a mortise and tenon process. A welding cup structure is provided at the tail of the ejector pin body.

[0014] In some embodiments of the present invention, the firing pin insulation assembly includes a first firing pin insulator, a second firing pin insulator, and a third firing pin insulator, wherein the firing pin spring is sleeved on the second firing pin insulator and one end abuts against the third firing pin insulator.

[0015] In some embodiments of the present invention, the conductive rod insulation assembly includes a first conductive rod insulation, a second conductive rod insulation, and a third conductive rod insulation, wherein the firing pin spring is sleeved on the second conductive rod insulation and one end abuts against the third conductive rod insulation.

[0016] Compared with the prior art, the beneficial effects of the double-click firing mechanism for dual-chamber riot guns provided by the embodiments of the present invention are as follows: it provides technical support for the next generation of constant kinetic energy strike weapons, and provides a knob structure with three gear selection, which can be widely used in the field of electrical signal control; in addition, it can also be used in pin structures in confined spaces, and can be widely used in the field of circuit connection of precision instruments and equipment.

[0039] The above and other aspects, features and advantages of this application will become more apparent when taken in conjunction with the accompanying drawings and in view of the following detailed description.

[0040] Specific embodiments of this application are described below with reference to the accompanying drawings; however, it should be understood that the claimed embodiments are merely examples of this application, which can be implemented in various ways. Well-known and / or repeated functions and structures are not described in detail to ascertain the true intent based on the user's historical operations, and to avoid unnecessary or redundant details that would obscure this application. Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in various ways with substantially any suitable detailed structure.

[0041] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0042] This invention provides a double-click firing mechanism for a dual-chamber riot gun, such as... Figures 1 to 9 As shown, the method includes:

[0043] The firing pin assembly 1 includes two firing pins 6, a firing pin insulating assembly located between the two firing pins 6 for isolation, two firing pin springs 7 respectively sleeved on the firing pins 6 and pushing against the firing pins 6 so that the firing pins 6 can always be in contact with the bottom of the ammunition, and a firing pin plug 11 for sealing the insulating assembly.

[0044] The conductive rod assembly 2 includes two conductive rods 12, a conductive rod insulating assembly located between the two conductive rods 12 for isolation, two conductive rod springs 13 respectively sleeved on the conductive rods 12 and pushing against the conductive rods 12 so that the conductive rods 12 and the conductive block 18 can always be in a connected state, and a conductive rod plug 16 for sealing the conductive rod insulating assembly.

[0045] The firing position selection component 3 includes a body 19, a knob 21 installed inside the body 19 and capable of rotating to change the firing position, four ejector pin assemblies 22 installed inside the knob 21, four conductive plates 20 fixed at the input and output interfaces of the body 19 respectively, thin wires connected to the outside of the conductive plates 20, and the inside of the conductive plates 20 connected to the ejector pin assemblies 22, with the tails of two ejector pin assemblies 22 connected to the same path. By rotating the knob 21, different firing positions can be selected.

[0046] During feeding, firing, and ejection, when the bolt 4 is in the rear-hook position, the firing pin protrudes from the cartridge base under the action of the firing pin spring 7, and the conductive rod 12 retracts under the pressure of the receiver 5. After the bolt 4 pushes the cartridge into the chamber and completes the locking, the firing pin is pressed back into the bolt 4 by the bottom surface of the cartridge, and the conductive rod 12 connects to the conductive plate 20 on the receiver 5 under the action of the conductive rod spring 13, completing the conduction of the entire circuit. When the bolt 4 unlocks and moves rearward to eject the cartridge, the conductive rod 12 retracts immediately under the pressure of the receiver 5, and the firing pin extends after ejection, cutting off the circuit.

[0047] In the aforementioned double-click firing mechanism for a dual-chamber riot gun, interfaces are provided between each component for connection with thin wires, and sufficient slack is left to ensure normal operation of the mechanism. The above scheme adopts a longitudinal arrangement of the double-click pins. Compared with other arrangements, its advantage is that although it occupies longitudinal space, it does not require a hammer due to the use of electric ignition, and therefore does not increase the overall size compared to traditional firearms.

[0048] Specifically, the firing position selection component 3 provides three firing positions. Only when the knob 21 is rotated to the fixed position does the firing pin protrude, thus completing the circuit. When the knob 21 is in other positions, the circuit is disconnected. The firing pin, the conductive rod 12, and the two firing pin assemblies 22 that share the same path with the firing position selection component 3 are soldered together with a thin wire, leaving a certain margin to ensure reliable conduction even when the mechanism is in operation.

[0049] To facilitate understanding of the above technical solutions, a detailed description of the technical solutions is provided below with reference to the accompanying drawings:

[0050] like Figure 1 As shown, the double-firing mechanism for a dual-chamber riot gun consists of a firing pin assembly 1, a conductive rod assembly 2, a firing position selection assembly 3, and several connecting wires. The firing pin assembly 1 and the lower half of the conductive rod assembly 2 are installed inside the bolt 4 and reciprocate with the bolt 4. The upper half of the conductive rod assembly 2 and the firing position selection assembly 3 are fixedly installed on the receiver 5. Only when the bolt 4 is in the locked state do the upper and lower parts of the conductive rod assembly 2 contact, activating the firing mechanism. When the bolt 4 is in other positions, the firing mechanism is disengaged, greatly improving shooting safety.

[0051] like Figure 2 As shown, the firing pin assembly 1 consists of a firing pin 6, a firing pin spring 7, a first firing pin insulator 8, a second firing pin insulator 9, a third firing pin insulator 10, and a firing pin plug 11. The firing pin 6, firing pin spring 7, and firing pin insulator assembly are inserted from the rear of the bolt 4, and finally, the push rod is tightened to complete the installation of the firing pin assembly 1. The compression force of the firing pin spring 7 ensures that the firing pin 6 remains in contact with the bottom of the ammunition.

[0052] like Figure 3As shown, the conductive rod assembly 2 consists of a conductive rod 12, a conductive rod spring 13, a first conductive rod insulator 14, a second conductive rod insulator 15, a third conductive rod insulator 17, a conductive rod plug 16, and a conductive block 18. The assembly of the conductive rod assembly 2 is similar to that of the firing pin assembly 1, and the conductive rod spring 13 also ensures the connection between the conductive rod 12 and the conductive block 18.

[0053] like Figure 4 As shown, the firing position selection component 3 consists of a body 19, conductive plates 20, a knob 21, and a firing pin assembly 22. The knob of the firing position selection component 3 is installed inside the body 19 and can rotate freely in all directions to change positions. Four conductive plates 20 are fixed at the input and output interfaces of the body 19, respectively. Thin wires are connected to the outside of the conductive plates 20, and the inside of the conductive plates 20 is connected to the firing pin assembly 22. The firing pin assembly 22 is installed inside the knob, and the tails of two firing pins with the same path are soldered with thin wires, thus forming a complete circuit for one position. The three positions of the firing position selection component are as follows: Figures 5 to 7 As shown.

[0054] like Figure 8 As shown, the ejector pin assembly consists of an ejector pin head 23, an ejector pin body 24, and an ejector pin spring 25. After the ejector pin head presses the ejector pin spring into the ejector pin body, the movement space of the ejector pin head is restricted around the ejector pin body using a mortise and tenon joint process. A welding cup structure is designed at the tail of the ejector pin body to facilitate welding operations.

[0055] like Figure 9 As shown, the dual-chamber variable muzzle velocity ammunition includes a main cap 26, a spherical projectile 27, a sabot 28, a gasket 29, a pressure control plate plug 30, a pressure control plate 31, a high-pressure chamber 32, a primer 33, an annular primer assembly 34, a main pressure ring 35, and a cartridge case 36.

[0056] As can be seen from the above technical solutions, the double-click firing mechanism for dual-chamber riot guns provided by the above embodiments of the present invention provides technical support for the next generation of constant kinetic energy strike weapons, and provides a knob structure with three gear selection, which can be widely used in the field of electrical signal control; in addition, it can also be used in pin structures in confined spaces, and can be widely used in the field of circuit connection of precision instruments and equipment.

[0057] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
