Technical Field
[0001] This utility model relates to the field of connector technology, and in particular to a shotgun adapter that can be installed on a grenade launcher. Background Technology
[0002] In modern military and law enforcement operations, facing complex and ever-changing combat environments and diverse target types, single-function weapons often cannot meet actual needs. For example, in missions such as urban counter-terrorism, border patrol, and security of important locations, there may be simultaneous encounters with targets that need to be struck at long range and emergencies that need to be dealt with at close range.
[0003] Traditional grenade launchers are mainly used to fire grenades, with a large kill radius and long range, making them suitable for striking group targets or conducting area blockade. However, in certain situations, such as when it is necessary to accurately strike small targets like drones or to conduct rapid fire in close-range environments, the limitations of grenade launchers become apparent. While shotguns have powerful lethality and high accuracy at close range, their range is relatively short, and they are relatively inconvenient to carry and operate. Therefore, this application provides a shotgun adapter that can be mounted on a grenade launcher to meet the requirements. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a shotgun adapter that can be installed on a grenade launcher to solve the technical problem that traditional grenade launchers are good at firing grenades, with a large kill radius and long range, and are suitable for striking group targets and area blockade, but are not accurate when precisely striking small targets such as drones. Shotguns, although powerful at close range and with a high hit rate, have short range and are inconvenient to carry and operate.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

Detailed Implementation
[0023] The following is a detailed description of a shotgun adapter that can be installed on a grenade launcher, provided by the present invention, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.
[0024] like Figures 1-3 As shown, an embodiment of this utility model provides a shotgun adapter that can be installed on a grenade launcher, including a grenade launcher 1 and an adapter 2 connected inside the grenade launcher 1. The adapter 2 includes a firing tube 201, which is one of the core components of the entire adapter 2. The firing tube 201 is divided into a loading area 202 and a firing area 203. The loading area 202 is used to load shotgun shells 6. When performing interception missions against targets such as drones, shotgun shells 6 are inserted into the loading area 202. The firing area 203 is responsible for guiding the shotgun shells 6 out when the grenade launcher 1 is fired. The end of the firing tube 201 near the loading area 202 is specially provided with an ejection groove 4, which is used to smoothly eject the shotgun shells 6 after they are fired, facilitating subsequent continuous loading and firing operations.
[0025] The adapter tube 204 is circular with a diameter of 35mm, which can be tightly and securely connected to the interior of common grenade launchers 1. The main function of the adapter tube 204 is to act as a bridge between the shotgun shell 6 and the grenade launcher 1, so that the shotgun shell 6 can be installed in the grenade launcher 1 and the launcher originally used to fire grenades can be compatible with the firing of shotgun shell 6.
[0026] A connector 3 is installed on the launch tube 201 to increase the connection strength between the adapter tube 204 and the grenade launcher 1. The connector 3 includes a fixing sleeve 301, which is firmly fixed to the outer wall of the launch tube 201. Several first connecting strips 302 are fixedly arranged on the side of the fixing sleeve 301 near the adapter tube 204. Simultaneously, several second connecting strips 303 are also fixedly arranged on the outer wall of the grenade launcher 1. Connecting rings 304 are detachably connected to both the first and second connecting strips 302 and 303. Connecting ropes 305 are fixed to the connecting rings 304. The connecting ropes 305 are elastic connecting straps. The connecting rope 305, made of elastic rubber, effectively buffers the vibration and impact generated during firing while ensuring connection strength, further enhancing connection stability. Furthermore, the connecting ropes 305 are fixedly connected by wire 306, ensuring that the adapter tube 204 and grenade launcher 1 are tightly connected during firing and will not detach. In addition, the outer wall of the fixing sleeve 301 is provided with equidistant anti-slip textures 5. When the user installs or removes the adapter 2, the anti-slip textures 5 provide better grip friction, facilitating operation and preventing installation errors or equipment damage due to slippage.
[0027] When it is necessary to install shotgun shell 6 in grenade launcher 1 for tasks such as intercepting drones, first, insert shotgun shell 6 into the loading area 202 of launch tube 201. Then, hold launch tube 201 and slowly and accurately insert one end of loading area 202 into grenade launcher 1. Next, connect connecting ring 304 to the first connecting strip 302 and the second connecting strip 303 respectively. At this time, the elastic rubber strip connecting rope 305 will naturally stretch and be in a taut state. Finally, use wire 306 to fix the connecting ropes 305 together, completing the entire installation process of adapter 2. After completing the firing mission, if it is necessary to disassemble adapter 2, simply follow the reverse steps. First, remove connecting ring 304, then remove launch tube 201 from grenade launcher 1, eject shotgun shell 6 along ejection groove 4, then load new shotgun shell 6, and then insert one end of loading area 202 of launch tube 201 into grenade launcher 1.
[0028] It should be noted that after the shotgun 6 adapter 2 is installed, the firing mechanism of the grenade launcher 1 is activated, and the firing pin strikes the primer of the shotgun 6. After the primer is ignited, it ignites the propellant inside the shotgun 6. The propellant burns rapidly and generates a large amount of high-temperature and high-pressure gas. These gases form a strong pressure in the firing zone 203 of the firing tube 201, which propels the shotgun 6 forward along the firing tube 201 and finally ejects it from the front end of the firing tube 201, thereby achieving the purpose of launching the shotgun 6. During this process, the structural design of the adapter 2 ensures that the shotgun 6 can be launched stably under the action of the grenade launcher 1 and has a certain accuracy and range to meet the needs of intercepting targets (such as drones). The specific existing technology will not be elaborated here.
[0029] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details have been described in detail in the above preferred embodiments; however, those skilled in the art can fully understand this utility model even without these detailed descriptions.
[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
