The service is good. The 97 18.4mm riot gun consists of 78 parts and the clock weighs 4.78 kg. During the 60th anniversary of the founding of New China, the parade armed police team held an improved 97-type 18.44mm explosion-proof gun. The whole gun can't be completely decomposed into gun body and firing machine. Cylinder barrel, bolt assembly and floating body assembly 5. In an emergency, even without tools, guns can be quickly disassembled and replaced with keys, which fully embodies the convenience of disassembly and assembly of guns. Disassembly method: unscrew the cylinder fixing nut 1 counterclockwise by hand, and then remove the cylinder. Press the left switch reed with your right thumb, push the front handle forward, and then remove the downstream valve body assembly and bolt assembly. If necessary, you can also punch out the front connecting shaft 2 and the rear connecting shaft 3 with a punch, and pull the trigger holder outward to take out the starter assembly. The whole gun didn't completely decompose.
If it is a used gun, it can be wiped after it is not completely decomposed. The order of combination is opposite to that of decomposition.
(2) various shapes,
The 97 18.4mm riot gun, which is suitable for various environments, can have various shapes on the premise that the basic structure remains unchanged. This shape change is achieved by replacing the front handle, the hand guard, the rear handle, the fixed bracket and the folding bracket. Due to the difference in shape and structure, the shape, size and holding mode of riot gun have changed, which is more suitable for police officers who perform tasks in different environments and occasions. The transformation method is very simple, and the operator can replace it in a few minutes according to the requirements of the manual, which meets the wishes of users.
This gun can be changed into four shapes. For example, changing the front handrails of two shoulder guns into front handrails becomes six shapes.
Basic types of riot guns. This model has front and rear grips, and the whole gun is short, which is easy to carry and conceal. The front and rear handles are made of high-strength nylon reinforced plastic injection molding, which is finger-shaped and has a more comfortable grip. Front armguard and rear handle types. Different from the basic model, the front handle is replaced by a hand guard, which is more convenient to carry, and the height of the fire line is greatly reduced, which improves the concealment. The hand guard is also injection molded with nylon reinforced plastic.
Types of front armguard and rear fixed stock. Compared with the front armguard and the rear handle, the latter is a fixed stock rather than a rear handle. This gun is characterized by stable shooting, high aiming accuracy and good stability, especially when firing tear gas.
Front hand guard and rear folding inventory types. Compared with the front armguard and the rear fixed thigh, the latter is a folded thigh rather than a fixed thigh. This kind of gun is characterized in that the stock can be folded when it is equipped with a belt, and it has the characteristics of basic type, front armguard and rear handle type. When it is used, it has the characteristics of opening and fixing the stock with the front armguard.
(3) the structural design is reasonable,
The 97 18.4mm riot gun with good reliability pays attention to safety requirements in structural design. In order to prevent the bolt from going off when the locking is unreliable, there is a limit groove at the end of the locking clip. When the lock clip does not rise in place, even if the needle is struck, the needle cannot move forward, so the primer of the bullet cannot be fired, which plays an insurance role.
In order to ensure that the locking clamp iron is locked in place before firing, the gun is also equipped with a non-locking safety to ensure that the traveling body parts can be fired only after they are in place, while the traveling body parts are in place behind the locking clamp iron and the bolt is in place in front of the locking clamp iron. The constraint relation of this structure ensures that the bolt is in place first, then the clamp iron is locked in place, and finally the driving body is in place, and the movement of the driving body and the walking body assembly is synchronous, so this constraint relation ensures that the hammer can be hammered. In order to prevent the trigger from accidentally touching and firing when not shooting, the gun is also equipped with a trigger safety, which can be realized by pressing left and right when using, which is very convenient. Due to the effective measures taken in the structure, the 97 18.4mm riot gun has high safety and reliability in use.
Adopt advanced processing technology to ensure the reliable performance of products, and at the same time strive to reduce the manufacturing cost of products. Therefore, some chip-free or chip-less processing techniques, such as spinning, die casting, precision casting, stamping, etc., are adopted, and a large number of injection molded parts are also used. Among 78 parts, as many as 29 parts are processed by the above method, which not only saves materials, but also reduces costs and improves efficiency.
The main elements are caliber 18.4mm, total gun length 660mm, barrel length 425mm, total gun weight 2.65kg, firing mode, single magazine capacity 5, ammunition type 18.4mm, tear gas 18.4mm, and dye cartridge 18. 4mm riot kinetic energy bomb 18.4mm riot kinetic energy shotgun 18.4mm killing shotgun (if necessary) The failure rate of 40mm tear rifle Grenade is less than 5‰, and its service life is more than 3,000 rounds.
Type 97 18.4mm riot gun passed the technical appraisal organized by the Ministry of Public Security in May 1997 and obtained the national patent. For more than a year, it has been tried out in the police forces of 10 provinces and municipalities directly under the central government, and it has been well received by users because of its simple structure, reliable performance, convenient use, easy maintenance, various types of missiles and high initial hit rate.
Type 97 18.4mm riot gun is a new member of China's police riot weapon. The gun has reliable performance, and its processing quality ranks at the leading level in China. It has been exported to many countries in the world and has a place in the international market.
