Description

Technical Field

[0001] This invention belongs to the field of firearms design, specifically relating to a closed non-disintegrating ammunition belt that enables single-pass feeding of large-rimmed ammunition. Background Technology

[0002] The threat posed by drones, especially micro-drones, is increasing. However, counter-drone technology, particularly large air defense weapons and electronic jamming equipment targeting swarms, is primarily used for positional defense and cannot be widely deployed to individual soldier squads. Individual soldier squads face the threat of micro-drones in combat, and conventional individual weapons are ineffective in such close-range, terminal-stage drone interception scenarios. Real-world testing has shown that shotguns have a high interception probability against drones, making them a crucial countermeasure for individual soldier squads against the micro-drone threat. Shotguns fire multiple projectiles at once, creating a spatial dispersion barrage that inflicts area damage on incoming drones. This method offers advantages such as direct response, no need for precise aiming, and low cost. It is precisely the inherent destructive power and low cost of shotguns in terminal-stage drone counter-attacks that enhances the ability of individual soldiers to counter the drone threat.

[0003] However, conventional shotguns also have some shortcomings in countering drones. Shotguns mostly use tubular magazines or pouches for ammunition feeding. Due to the large size of shotgun shells, the capacity is relatively small, making it impossible to sustain a continuous counter-drone capability. Belt-fed systems, on the other hand, have a large capacity and can provide a continuous and stable ammunition supply. However, existing shotgun feeding methods do not use belt structures. A key reason for this is that shotgun shells have a large, outward-protruding rim. If the shell is pushed forward like a conventional belt-fed ammunition, the rim diameter of the shotgun shell is larger than the shell's diameter and also larger than the aperture that the belt can pass through. This protruding rim will interfere with the belt, hindering forward movement. This makes it impossible for shotgun shells, with their large rims, to achieve a single-pass, single-feed operation like other types of ammunition. Therefore, a new belt structure needs to be designed to enable single-pass feeding of shotgun shells, providing a continuous and stable firepower output for individual soldiers and squads in countering drones. Summary of the Invention

[0004] The purpose of this invention is to provide a closed, non-disintegrating ammunition belt that enables single-pass feeding of large-rimmed ammunition, thereby solving the problem that existing standard large-rimmed shotgun shells cannot use a single-pass feeding belt, and realizing high-capacity continuous firepower output of shotgun weapons.

[0005] The technical solution to achieve the purpose of this invention is as follows:

[0006] A closed non-disintegrating ammunition belt for single-feeding of large-rimmed munitions includes:

[0007] Multiple closed links are used to secure the ammunition, preventing it from loosening, falling off, or shifting in attitude during feeding, and ensuring that the ammunition axis coincides with the axis of the closed links; during feeding, it can elastically deform to expand the inner diameter, enabling one-time ammunition feeding;

[0008] Multiple connecting rings are set between the front and rear sides of the first connecting ring fixing seat and multiple closed links, connecting the first connecting ring fixing seat and multiple closed links in series to form the main body of the ammunition belt, ensuring that the ammunition is arranged neatly and with consistent spacing; two adjacent connecting rings on the same side partially overlap and fit into the same closed link, realizing the sequential connection of closed links and the connection between adjacent connecting rings.

[0009] The spring hook, together with the boss on the main body of the chain, restricts the position of the connecting ring in the direction of the first connecting ring fixing seat and multiple closed chain links, keeping the chain from falling apart;

[0010] The initial connecting ring fixing seat is used to fix the initial connecting ring and acts as a guide for loading the ammunition belt into the ammunition feeding mechanism.

[0011] The significant advantages of this invention compared to existing technologies are:

[0012] (1) This ammunition belt structure is the first to realize the one-time feeding method of ammunition belt for large rim ammunition, which solves the difficulty of one-time feeding of large rim ammunition and can provide a continuous, stable and large-capacity ammunition supply.

[0013] (2) The spring belt has a simple structure, few parts, stable and reliable operation, and is not prone to failure.

[0014] (3) The main component of the ammunition belt is made of engineering plastic, which is lightweight. Compared with metal ammunition belts, it can carry more ammunition and provide better firepower sustainability when carrying the same weight of ammunition and ammunition belt.

[0015] (4) The link of the ammunition belt can rotate around the center of the link axis. Compared with the general non-disintegrating ammunition belt, the rotation angle between its links is larger, the rotation is more flexible, the applicable scenarios are wider, and it effectively saves space. The ammunition belt box of the same volume can hold more ammunition.

[0016] (5) This ammunition belt can be adapted to shotgun shells of different lengths, making it highly versatile. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] Combination Figure 1 This invention discloses a closed, non-disintegrating ammunition belt for single-feeding of large-rimmed ammunition, comprising a closed link 1, a connecting ring 2, a spring hook 3, and a first connecting ring fixing seat 4. The connecting ring 2 connects the closed link 1 to the first connecting ring fixing seat 4 in series, and the spring hook 3 constrains the ammunition belt to prevent it from disintegrating. The closed link 1 secures the ammunition, preventing it from loosening, falling off, or shifting during feeding, and protecting it from impacts and dust corrosion. The first connecting ring fixing seat 4 fits onto the front and rear connecting rings 2, using its stepped end face and cooperating with the spring hook 3 to constrain and fix the front connecting ring 2, protecting the unused portion of the front connecting ring 2 from collision and breakage with the gun body, and also serving as a guide for loading the ammunition belt into the feeding mechanism, facilitating personnel operation.

[0026] Combination Figure 2 Multiple connecting rings 2 are fitted onto both the front and rear sides of the closed link 1 and the first connecting ring fixing seat 4. Adjacent connecting rings 2 on the same side are arranged in two overlapping rows, fitting into the closed link 1 and the first connecting ring fixing seat 4 from both ends, and tightly abutting the boss in the middle of the closed link 1 and the first connecting ring fixing seat 4. By partially overlapping two adjacent connecting rings 2 on the same side into the same link 1, both the sequential connection of the links 1 and the connection between adjacent connecting rings 2 are achieved. The first connecting ring fixing seat 4 provides support and fixation for the connecting ring 2 portion of the first end of the closed link 1 that is not fitted with the first ring. Its outer and inner diameters are consistent with those of the closed link 1 to avoid interference with the feeding and feeding mechanisms due to its special structure when installed in the ammunition feeding mechanism. The width of the boss in the middle of the first connecting ring fixing seat 4 is greater than the width of the boss in the middle of the closed link 1.

[0027] Combination Figure 3To ensure the planar and torsional flexibility of the ammunition belt, a certain gap is left between the diameter fit of the closed link 1, the connecting ring 2, and the first connecting ring fixing seat 4. To prevent the ammunition belt from unraveling, the spring hook 3 is inserted into the through holes on the upper and lower sides of the connecting ring 2 to connect the connecting rings 2 on both sides of the boss, providing a pulling force from the front and rear sides towards the middle of the connecting ring 2. Together with the boss in the middle of the closed link 1, it restricts the position of the connecting ring 2 to remain unchanged, preventing the connecting ring 2 from gradually loosening in the direction of the ammunition axis due to the accumulation of gaps as the ammunition belt grows. The connecting ring 2 is used to connect the individual links to form the main body of the ammunition belt, ensuring that the ammunition is arranged neatly and with consistent spacing, facilitating ammunition feeding.

[0028] Combination Figure 4 The connecting ring 2 can rotate around the side wall of the closed link 1. When rotating, there is no need to consider the interference between the side walls of adjacent links. Compared with the non-disintegrating elastic chain that generally uses spiral steel wire as the middle part of the link, it requires a smaller pitch, has a wider range of rotation angles (greater than ±90 degrees), is more flexible in rotation, and is applicable to a wider range of scenarios.

[0029] Combination Figure 5 , Figure 6 The closed link 1 has three circumferentially evenly distributed legs at 120 degrees on each of its front and rear outer walls. As the ammunition is pushed inward from the front of the link, the projectile flange sequentially opens the front and rear legs. The inclined surfaces at the ends of the three rear legs contact the inclined surfaces of the projectile flange, securing the projectile flange between the inclined surfaces of the legs and the tail end face of the closed link 1. The diameter of the circle formed by the inner walls of the legs is slightly smaller than the diameter of the ammunition casing. The contact friction between the legs and the projectile, along with the elastic deformation of the legs, provides resistance to the projectile, preventing it from accidentally falling out of the link. Furthermore, the diameter of the circle formed by the three front legs and the three rear legs, slightly smaller than the diameter of the ammunition casing, also provides radial centripetal force to the ammunition, ensuring that the ammunition axis coincides with the link axis, preventing attitude deviation and facilitating projectile feeding.

[0030] During feeding, the firearm's feeding mechanism extends from the hole at the tail of link 1, pressing against the bottom face of the ammunition and pushing it forward. The protruding bottom edge of the ammunition first contacts the inclined surface of the rear support leg of link 1, generating a radially outward force on the support leg. This causes the support leg to elastically deform, and the diameter of the circle formed by the three rear support legs gradually increases until it exceeds the diameter of the ammunition's bottom edge, forming an aperture through which the ammunition's bottom edge can pass. The ammunition passes over the rear support leg. At this time, the diameter of the circle formed by the front support leg remains unchanged, still providing a radial centripetal force on the side wall of the ammunition to prevent attitude deviation and ensure that the ammunition is aligned with the chamber. As the ammunition continues to be pushed forward, it passes over the front support leg in the same way, and the ammunition is completely disengaged from the ammunition belt. This achieves a single-pass, single-feed operation for ammunition with a large bottom edge.

[0031] Combination Figure 7The tail end of link 1 has a square notch on its side wall, allowing personnel to easily check whether the ammunition is properly installed when loading it into the ammunition belt. The main body of the ammunition belt (closed link 1 and connecting ring 2) is made of engineering plastic, which is lightweight. Compared to metal ammunition belts, it can carry more ammunition while carrying the same weight of ammunition and ammunition belt, providing better firepower sustainability.
