Dummy Ammo

Abstract

A dummy ammo comprises a counterweight component and a contour component, wherein the counterweight component comprises at least one counterweight block, and the contour component comprises at least one cartridge shell; the cartridge shell is provided with at least one inner wall, and the inner wall defines at least one cavity; the counterweight block is arranged in the cavity; when the counterweight block is fixed, the dummy ammo has a weight distribution close to that of a live ammo, so that the problem of being difficult to eject during training can be solved, and the experience is better when being used.

1 . A dummy ammo, comprising at least one counterweight component and at least one contour component, wherein said contour component has at least one longitudinal axis, and said contour component defines at least one front end and at least one rear end; and
 said contour component comprises at least one cartridge shell, and said counterweight component comprises at least one counterweight block, wherein said cartridge shell is provided with at least one inner wall; and said inner wall defines at least one cavity, and said counterweight block is fixed in said cavity; and said cartridge shell is provided with at least one counterweight opening which is close to said front end; and   wherein when said counterweight component is fixed, a center of gravity of said counterweight component is close to said counterweight opening and far away from said rear end in a direction parallel to said longitudinal axis.   
     
     
         2 . The dummy ammo according to  claim 1 , wherein said counterweight block is fixed in said cartridge shell by ultrasonic fixing. 
     
     
         3 . The dummy ammo according to  claim 1 , wherein said counterweight block is fixed in said cartridge shell by gluing. 
     
     
         4 . The dummy ammo according to  claim 1 , wherein said cartridge shell further comprises a basic positioning part, and said counterweight block is fixedly connected with said cartridge shell through said basic positioning part. 
     
     
         5 . The dummy ammo according to  claim 4 , wherein said basic positioning part is formed by the protrusion of said inner wall of said cartridge shell. 
     
     
         6 . The dummy ammo according to  claim 5 , wherein said basic positioning part is provided with at least one counterweight accommodating cavity, which is larger than an inner diameter of said cartridge shell and smaller than an outer diameter of said cartridge shell. 
     
     
         7 . The dummy ammo according to  claim 6 , wherein said counterweight block is fixed in said counterweight accommodating cavity by way of fixed connection. 
     
     
         8 . The dummy ammo according to  claim 6 , further comprising at least one pressing block, which is arranged at said counterweight opening and cooperates with said basic positioning part to fix said counterweight block into said counterweight accommodating cavity. 
     
     
         9 . The dummy ammo according to  claim 6 , wherein the contour component comprises two cartridge shells, and when the two cartridge shells are spliced with each other, the corresponding two basic positioning parts enclose to form said counterweight accommodating cavity. 
     
     
         10 . The dummy ammo according to  claim 9 , wherein the two cartridge shells are spliced by ultrasonic welding. 
     
     
         11 . The dummy ammo according to  claim 4 , wherein said contour component has a same external contour as a live ammo, and said contour component further comprises at least one base, which is close to said rear end; and said cartridge shell is connected with said base, the whole counterweight block is completely fixed in said cavity, and a density of said counterweight block is different from that of said cartridge shell. 
     
     
         12 . The dummy ammo according to  claim 11 , wherein one end of said cartridge shell far from said counterweight opening is provided with at least one cartridge shell receiving part, and said cartridge shell receiving part is provided with at least one cartridge shell receiving cavity. 
     
     
         13 . The dummy ammo according to  claim 12 , wherein said base defines at least one top surface and at least one bottom surface opposite to said top surface; and a joint part is set on said top surface, and comprises at least one receiving sidewall which has a tendency to protrude away from said bottom surface; and the joint part further comprises at least one joint cavity, and said receiving sidewall covers at least a part of said joint cavity; and
 wherein, when said cartridge shell is connected with said base, said cartridge shell receiving part contacts said top surface, and said cartridge shell receiving cavity covers at least part of said receiving sidewall.   
     
     
         14 . The dummy ammo according to  claim 11 , wherein said base comprises at least one top surface and at least one bottom surface opposite to said top surface, and said bottom surface comprises at least one primer cavity. 
     
     
         15 . The dummy ammo according to  claim 14 , wherein said primer cavity is provided with a shock absorber, which is made of a shock absorbing material. 
     
     
         16 . The dummy ammo according to  claim 11 , wherein said cartridge shell is made of a material with a hardness lower than that of said base, and said base is made of a metal material. 
     
     
         17 . The dummy ammo according to  claim 1 , further comprising at least one distinguishing part, which is arranged on said contour component and used for distinguishing the dummy ammo from a live ammo. 
     
     
         18 . The dummy ammo according to  claim 17 , wherein said distinguishing part comprises at least one distinguishing hole, and said distinguishing hole is arranged on said cartridge shell. 
     
     
         19 . The dummy ammo according to  claim 18 , wherein said distinguishing hole is a circular opening arranged in said cartridge shell, and said circular opening penetrates through said cartridge shell. 
     
     
         20 . The dummy ammo according to  claim 17 , wherein said distinguishing part comprises a recess arranged on said cartridge shell, and said recess is filled with pigment.
