Ammunition primer side firing structure

Abstract

The invention discloses an ammunition primer side firing structure, belongs to the field of ammunition primers, and relates to a mechanical side firing structure device for launching an ammunition primer for a non-seating gun. The lighter the weight of a single-soldier carried weapon is required, the better the single-soldier carried weapon is required, the safety requirement is high, a traditional single-soldier barrel type weapon ignition device mostly adopts bottom direct striking type ignition, a primer is installed at the center bottom of ammunition, the weight is heavy, and in the latch closing process, danger may be generated due to the fact that a latch body strikes a pin and the primer is hit in the latch closing process; aiming at the situation, the ignition tube structure of the ignition device is designed, the firing mode is changed into lateral firing from original direct firing, and on the basis that the weight of a firing device is reduced, the risk generated when direct firing fails can be effectively avoided.

Description

Technical Field

[0001] This invention belongs to the field of ammunition primers and is a side-firing structure for ammunition primers, used in a recoilless rifle to fire ammunition primers via a mechanical side-firing structure device. Background Technology

[0002] Lightweight individual soldier weapons are essential for ease of transport and maneuverability, while also prioritizing safety, directly impacting soldier well-being. Traditional individual cylindrical weapons typically employ bottom-firing direct-fire mechanisms, with the primer mounted at the center bottom of the ammunition. This not only results in significant weight but also poses a risk of malfunction during breech closing, where a firing pin failure could cause the breech to strike the primer, creating a dangerous situation. Therefore, to address these issues, a new ignition tube structure has been designed for the ignition device. This design changes the firing method from direct-fire to side-fire, effectively reducing the weight of the firing mechanism and mitigating the risks associated with direct-fire malfunctions.

[0003] In the design process of recoilless rifles, due to the special open-type balanced internal ballistic principle of recoilless rifles, the nozzle of the ammunition cartridge is circumferentially open, which is completely different from the bottom of the ammunition of closed-bolt guns. Therefore, the traditional bottom-face firing method cannot be used. Thus, a mechanical structure that fires the primer of the ammunition from the side needs to be designed to meet the requirements of recoilless rifles.

[0004] Therefore, in view of the above situation, a recoilless gun ammunition primer side-firing structure was designed. Summary of the Invention

[0005] The purpose of this invention is to design a firing structure that can be reliably fired from the side, is lightweight, and is safe and reliable. The side firing structure is characterized by being composed of a firing mechanism (1), a firing pin spring (2), a firing rod (3), a hammer (4), a hammer shaft (5), a cartridge case (6), a primer (7), a breech (8), a firing pin (9), and a firing pin chamber (10). The mechanism is such that the firing mechanism (1) fires and releases the firing pin spring (2), which drives the firing rod (3) and changes the firing direction through the hammer (4) and the hammer shaft (5) to strike the firing pin (9) on the breech (8). The firing pin (9) strikes the primer (7) on the cartridge case (6), thereby realizing the side firing function.

[0006] This side-firing method not only enables side-firing but also has higher firing energy efficiency than traditional bottom-firing. It not only satisfies the open-balanced internal ballistics of recoilless guns but also reduces the firing spring force (2) from 150N to 80N for the Type 78 82 recoilless gun. Furthermore, it ensures a 5-fold safety factor for firing energy. Attached Figure Description

[0011] This invention provides a side-firing structure for recoilless rifles. For example... Figure 1 In the schematic diagram of the side-firing structure of the recoilless rifle shown, during firing, the firing mechanism (1) releases the firing pin spring (2), which drives the firing rod (3). The firing rod (3) accelerates continuously under the energy of the firing pin spring (2) and eventually strikes the hammer (4). The hammer (4) rotates circumferentially under the drive of the hammer shaft (5), changing the firing direction and striking the firing pin (9). The firing pin (9) strikes the primer (7) positioned by the breech (8) and the ammunition cartridge (6) under the guidance of the firing pin chamber (10), transferring the energy of the firing spring (2) to the primer (7), thus achieving side firing and completing the firing.
