Description

Technical Field

[0001] The utility model relates to a 9 mm training cartridge, belonging to the technical field of ordnance manufacturing. Background Art

[0002] At present, there is no training cartridge for 9 mm series firearms. When cleaning, repairing firearms or when recruits practice operating firearms, only dry firing can be carried out. At this time, the firing pin rigidly impacts the bolt without buffering, which has an adverse effect on the service life of the firing pin and the bolt. Summary of the Invention

[0003] The purpose of the utility model is to provide a reusable training cartridge without pyrotechnics, which is safe to use and can protect the firing pin during the operation practice, cleaning and repair of firearms.

[0004] The technical solution of the utility model: a 9 mm training cartridge, including a bullet head 1, a cartridge case 2, a buffer pad 3, and a primer shell 4; the buffer pad 3 is placed into the primer shell 4; the primer shell 4 containing the buffer pad 3 is pressed into the cartridge case 2; the bullet head 1 is pressed into the cartridge case 2 and is subjected to circumferential crimping.

[0005] The cartridge case 2 is a barrel-shaped body, the inner hole diameter of which is adapted to the bullet head 1 and has an interference fit with the outer diameter of the primer shell 4.

[0006] The buffer pad 3 is a columnar structure, made of rubber or silica gel material, and its outer diameter is matched with the inner diameter of the primer shell 4.

[0007] The buffer pad 3 is made of rubber or silica gel material.

[0008] The primer shell 4 is a barrel-shaped structure with a hole at the bottom, and the diameter is 2 mm to 3 mm.

[0009] The mouth part of the training cartridge is circumferentially crimped for 1 mm to 3 mm.

[0010] The beneficial effect of the utility model: the utility model is a reusable training cartridge without pyrotechnics, which is safe to use and can protect the firing pin and the bolt during the operation practice, cleaning and repair of firearms. Brief Description of the Drawings

[0016] The present utility model will be further described below in conjunction with the accompanying drawings:

[0017] As Figure 1 shown, a 9-mm training cartridge includes a bullet head 1, a cartridge case 2, a buffer pad 3, and a primer case 4; the buffer pad 3 is placed in the primer case 4; the primer case 4 containing the buffer pad 3 is pressed into the cartridge case 2; the bullet head 1 is pressed into the cartridge case 2 and subjected to circumferential crimping.

[0018] As Figure 2 shown, the cartridge case 2 is a barrel-shaped body, the inner diameter of which is adapted to the bullet head 1 and has an interference fit with the outer diameter of the primer case 4.

[0019] As Figure 4 shown, the buffer pad 3 is a columnar structure and is made of rubber or silica gel material, and its outer diameter is matched with the inner diameter of the primer case 4.

[0020] As Figure 5 shown, the primer case 4 is a barrel-shaped structure with a hole at the bottom, and the diameter is 2 mm to 3 mm.

[0021] As Figure 3 shown, there is a circumferential crimping at 1 mm to 3 mm at the mouth of the cartridge.
