As shown inFIG.1andFIG.2, the present invention provides a dummy ammo, which includes a contour component and a counterweight component, wherein the contour component comprises a cartridge shell220and a base260; the contour component has approximately the same outline as the live ammo; and the counterweight component comprises a counterweight block120and a connector110.

The contour component is a rotating body, has at least one longitudinal axis, defines at least one front end and at least one rear end, and the base260is close to the rear end.

The cartridge shell220is provided with a counterweight opening223and an inner wall2201. The cartridge shell220has a generally cylindrical external structure. The counterweight opening223is close to the front end, and the counterweight opening223and the inner wall2201define a cavity, which is arranged inside the cartridge shell220, and the counterweight block120is arranged in the cavity.

The counterweight block120has a counterweight connecting part122, and a joint part2610is arranged on the base260.

At least one baffle ring is arranged at the rear end of the contour component, and the baffle ring has an outer diameter larger than that of the cartridge shell220, so as to better simulate the shape of live ammo and smoothly realize the function of loading ammunition.

The inner wall2201is provided with a basic positioning part2203, which protrudes from the inner wall2201and tends to approach the central axis of the cartridge shell220.

As shown inFIGS.1and2, in this embodiment, the basic positioning part2203has a cylindrical structure, the diameter and height of the basic positioning part2203are smaller than those of the inner wall2201, and the outer diameter of the counterweight block120is larger than that of the basic positioning part2203but smaller than that of the inner wall2201, therefore the basic positioning part2203can limit the position of the counterweight block120in the cartridge shell220. The connector110has a head, and the outer diameter of the head is larger than the inner diameter of the counterweight connecting part122. When the connector110is closely connected with the joint part2610, the counterweight block120can be limited to a specific position in the cartridge shell220, so that the dummy ammo can simulate the distribution of the center of gravity of the live ammo, and the problem that the dummy ammo is not easy to pop up when the center of gravity is low is solved, and the center of gravity does not change when it is used.

The basic positioning part2203is also provided with a reinforced positioning part2206, which protrudes from the basic positioning part2203and tends to approach the central axis of the cartridge shell220. In this embodiment, the reinforced positioning part2206has a slender rectangular parallelepiped shape and the length is consistent with the basic positioning part2203.

In this embodiment, the number of reinforcing positioning parts2206is four, and in other embodiments, it can be other numbers that meet the requirements of functions, such as single, two, and other shapes and structures, such as triangles, isosceles trapezoid, and the like.

In this embodiment, the counterweight block120has a cylindrical cross-sectional shape, and in other embodiments, it can also have other shapes such as triangle and square, and there is a structure or cavity inside the cartridge shell220that can match the shape of the counterweight block120.

The reinforcing positioning part2206can better restrict the movement of the counterweight block120, but it is not necessary. Therefore, in another embodiment, there may not be the reinforcing positioning part2206, and the position of the counterweight block120can be restricted only by the basic positioning part2203, which can be a single protrusion arranged on the inner wall2201, or a circular structure in another embodiment.

In this embodiment, the connector110is a bolt, the counterweight connecting part122is a through hole arranged in the center of the counterweight block120, and the counterweight block120can move on the connector110, and the joint part2610has a threaded part matched with the bolt. The connector110passes through the through hole to connect the counterweight block120, the cartridge shell220and the base260.

In another embodiment, the counterweight block120is fixed on the connector110, for example, the counterweight block120cannot move on the connector110by gluing, welding, hot melting, etc. At this time, there is no need to set the basic positioning part2203.

In another embodiment, the counterweight block120and the connector110are designed as an integral structure, therefore the head of the connector110is large and has a certain weight, which can also ensure the distribution of the center of gravity of the dummy ammo with simulated live ammo, and there is no need to set the basic positioning part2203.

As shown inFIG.2andFIG.3, the cartridge shell220is provided with a cartridge shell receiving part2210, a cartridge shell receiving cavity2215, a bottom surface2615on the base260opposite to the top surface2605, and a primer cavity270on the bottom surface2615. The primer cavity270is internally provided with a shock absorber300, and the shock absorber300includes at least a part of materials that can absorb shock.

In this embodiment, the shock absorber300is rubber. The shock absorber300is a solid structure with a cylindrical appearance and is fixed in the primer cavity270by bonding. In other embodiments, the shock absorber300can be made of other materials, such as silica gel, clastic synthetic materials and other materials that can meet the use requirements. The main function of the shock absorber300is to protect the structure of the firing ammunition of firearms and prolong the service life of firearms.

In other embodiments, the shock absorber300can be directly pressed into the primer cavity270, and the shock absorber300can only contain part of the shock absorber material.

As shown inFIGS.2to4, the joint part2610includes a receiving sidewall275and a joint cavity2612. The receiving sidewall275protrudes from the top surface2605in a direction away from the bottom surface2615, and the receiving sidewall275covers the joint cavity2612, which has a higher height than the receiving sidewall275, therefore a part of the joint cavity2612exceeds the top surface2605in a direction away from the bottom surface2615, while part thereof is from the top surface2605to the direction close to the bottom surface2615. This arrangement has the advantage of reserving more space and ensuring that the connector110can firmly confine the counterweight block120in the cartridge shell220.

In this embodiment, the cartridge receiving part2210is concave and the base260is convex, and the inner diameter of the cartridge receiving cavity2215is larger than the outer diameter of the receiving sidewall275, so that the cartridge receiving cavity2215can accommodate the receiving sidewall275, and when the base260is connected with the cartridge shell220, the base260is partially inserted into the cartridge shell220, and the base260can be better positioned.

In another embodiment, the cartridge shell receiving part2210is convex and the base260is concave, and the cartridge shell receiving part2210is inserted into the base260.

In other embodiments, the cartridge shell220and the base260do not adopt a concave-convex structure, and the cartridge shell220and the base260are in contact with each other through two planes, and the two planes are fixedly connected by gluing, hot melting and the like; the cartridge shell220and the base260can also be integrally cast or integrally formed without concave-convex structure.

As shown inFIG.2andFIG.5, in this embodiment, there is one connector110, and the connector110, the counterweight block120, the base260, the cartridge shell220and the shock absorber have a common axis, but it is not limited to this. In other embodiments, there may be two or more connectors110or two or more counterweight blocks120. At this time, the axes of the connector110, the counterweight block120, the base260, the cartridge shell220and the shock absorber are parallel.

As shown inFIG.6, this is the second embodiment of a dummy ammo, which includes a counterweight block120, a cartridge shell220, a base260, and a pressing block240. The counterweight block120is arranged at one end of the cartridge shell220near the counterweight opening223, and the cartridge shell220is provided with a basic positioning part2203protruding from the inner wall2201, so that the position of the counterweight block120can be limited. A pressing block240is arranged in the cartridge shell220in contact with the inner wall2201. The pressing block240can be made of a plastic material with certain elasticity or can be installed with the cartridge shell220by interference fit, therefore when installed in the cartridge shell220, the pressing block240can limit the movable position of the counterweight block120without other parts for connection.

In this embodiment, there is an interference fit between the base260and the cartridge shell220, and the base260is inserted between the cartridge shell220, therefore the base260and the cartridge shell220can also be closely connected.

In other embodiments, screw connection, snap connection, hot melt, cold pressing and other fixed connection methods can be adopted between the base260and the cartridge shell220.

In another embodiment, the base260and the cartridge shell220can also be integrally cast.

As shown inFIG.7, this is the third embodiment of a dummy ammo, which includes a counterweight block120, a cartridge shell220and a base260. By adopting an inlay injection molding process between the counterweight block120and the cartridge shell220, the cartridge shell220forms a counterweight accommodating cavity225around the counterweight block120at a position close to the counterweight opening223. At this time, the cavity of the cartridge shell is no longer a cylindrical structure, but a structure composed of two cylinders with different diameters. Since the counterweight accommodating cavity225has a diameter larger than the inner wall2201of the cartridge shell220, the counterweight block120can be stably fixed at a specific position in the cartridge shell220.

As shown inFIG.8, this is the fourth embodiment of the dummy ammo, which includes a counterweight block120, a cartridge shell220and a connector110. Compared withFIG.5, the fourth embodiment cancels the base260, and the cartridge shell220is made of metal. Because of its high density, the wall thickness of the cartridge shell220needs to be thinned to maintain the original weight and center of gravity distribution. At the same time, in order to adapt to the thinned cartridge shell220, the diameter of the counterweight block120changes and the diameter of the counterweight block120becomes larger. In order to maintain the original weight and center of gravity distribution, L2 is smaller than L1.

A joint cavity2612is arranged in the cartridge shell220, and the connector110enters the joint cavity2612, and the counterweight block120is fixed at a specific position in the cartridge shell220through the basic positioning part2203.

As shown inFIG.9, this is the fifth embodiment of a dummy ammo, which includes a counterweight block120, a cartridge shell220and a base counterweight280. The counterweight block120and the base counterweight280are all fixed in the cartridge shell220by an insert injection molding process. The counterweight block120and the base counterweight280are made of metal materials, and the cartridge shell220is made of plastic or nylon.

As shown inFIG.10, this is the sixth embodiment of a dummy ammo, which includes a counterweight block120, a cartridge shell220, a connector110, a base260and a bushing140.

The bushing140has a cylindrical structure. The inner diameter of the bushing140is larger than the outer diameter of the connector110, therefore the connector110can be put into the bushing140. The maximum outer diameter of the bushing140is smaller than the inner diameter of the inner wall2201of the cartridge shell220, therefore the bushing140can be put into the cartridge shell220. Both ends of the bushing140are in contact with the cartridge shell220and the counterweight block120respectively, and the base260has a joint cavity2612for matching the connector110. When the connector110enters the joint part2612, tightly connect the counterweight block120, bushing140, cartridge shell220, and base260.

As shown inFIG.11, this is the seventh embodiment of a dummy ammo, which includes a counterweight block120, a cartridge shell220and a base260. After the counterweight block120is put into the cartridge shell220through the counterweight opening223, the counterweight block120is fixed at a specific position of the cartridge shell220by gluing or ultrasonic fixing.

In this embodiment, the inner wall2201of the cartridge shell220is provided with the basic positioning part2203, which can limit the position of the counterweight block120and make it difficult for the counterweight block120to fall off. In another embodiment, the inner wall2201is not provided with the basic positioning part2203, and the counterweight block120is fixed at a specific position of the cartridge shell220only by gluing or ultrasonic fixation, and the counterweight block120is fixed at a specific position of the cartridge shell220.

As shown inFIG.12, this is the eighth embodiment of the dummy ammo, which includes a counterweight block120, a cartridge shell220, a connector and a base260. It further includes a distinguishing part330arranged on the cartridge shell220.

The function of the distinguishing part330is to distinguish live ammo from dummy ammo, so as to avoid confusing the two kinds of ammunition in actual use. In this embodiment, the distinguishing part330is a circular opening arranged in the cartridge shell220, which runs through the cartridge shell220. In other embodiments, the distinguishing part330can be an opening with other shapes, such as square, triangle and the like. It can also be a recess that does not penetrate the cartridge shell220, and the distinguishing part330is more obvious by filling the recess with pigment. The distinguishing part330can also be arranged at other positions, such as a recess on the base260.

As shown inFIG.13, this is the ninth embodiment of a dummy ammo, which includes a counterweight block120, two cartridge shells220and a base counterweight280. The two cartridge shells220are assembled by ultrasonic welding. Before assembling, the counterweight block120and the base counterweight280are put into the cartridge shells220.

As shown inFIG.14, this is the tenth embodiment of a dummy ammo, which includes two cartridge casings220, which are assembled by ultrasonic welding. The cartridge casings220are provided with protrusions at the position close to the counterweight opening223and at the other end far from the counterweight opening223. After assembling, a hollow cavity is formed in the middle of the cartridge casings220, so the weight distribution of ammunition is still close to that of live ammo.

In other embodiments, the hollow cavity is filled with other materials with lower density than the cartridge shell220, and there is no hollow cavity, but the weight distribution of ammunition is still close to that of live ammo.

The present invention has been described by preferred embodiments, and those skilled in the art will know that various changes and equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. The present invention is not limited by the specific embodiments disclosed here, and other embodiments that fall within the claims of this application are within the scope of protection of the present invention.
