Presided over the design of QSZ92 9mm pistol, QSZ92 5.8mm pistol and CF05 9mm light submachine gun.
design
Teacher Qing Shangsheng has shown extraordinary design talent in many projects. When developing the 64-type 7.62mm self-defense pistol, he innovatively designed the rifling spiral groove to increase the virtual mass of the automaton, thus delaying the unlocking and reducing the recoil speed of the automaton. In the development of Dongfeng-1 type 5.6 mm short bullet rapid-fire sport pistol and Dongfeng -5 type 5.6 mm standard sport pistol, the structure of pull back pressure built-in hammer was innovatively designed. In the development of 7.62mm gun family, the No.2 and No.3 firing mechanisms were successfully designed for the first time, and were successfully applied to submachine guns. When developing the 56-2 7.62mm submachine gun, four rows of compound arc magazines were developed and tested for the first time. When developing the 92-type 9mm pistol, it pioneered the forward-leaning large-capacity double-row compound magazine, obtained the national patent, innovatively designed the built-in hammer loading mechanism, and applied the barrel rotation locking mechanism to the pistol for the first time. When developing the 92-type 5.8mm pistol, the deceleration mechanism of the barrel rotary semi-free gun was pioneered and obtained the national patent.
Brief introduction of inventor
Teacher Qing Shangsheng has made such great achievements in the field of light weapons design. Today, he is still struggling in the front line of light weapons design and continues to display his talents for the cause he loves.
Recently, the reporter was delighted to hear that the CF05 9mm light submachine gun, with You Ching as the chief designer, passed the foreign trade design. The submachine gun pioneered a spiral cartridge feeding system with double-port support and random loading of displaced ammunition, and successfully designed an envelope structure with the spiral cartridge arranged directly above the barrel and the bolt parallel to the barrel. This unique and ingenious design structure gives people a refreshing feeling. With a keen interest in exploring the mystery of weapons, the reporter came to Chongqing Changfeng Machinery Co., Ltd. and had a long talk with Qing Lao about the design and research of the submachine gun.
Qing Shangsheng, 1940, 1 1, born in June, graduated from Chongqing Institute of Technology (now Chongqing University of Technology) majoring in light weapons, and was awarded the title of "Top Ten Scientific and Technological Workers in Southwest Military Industry" in June. 1996.
CF05 9mm light submachine gun was conceived in 1993 ~ 1994. When the design was finalized in 2005, four schemes were gradually improved. In the first scheme, the cartridge is used as the stock, and a two-way ammunition supply system is adopted (both the cartridge and the magazine can be used for ammunition). In the first scheme, I- 1 is equipped with two firing mechanisms and I-2 is equipped with three firing mechanisms. In the second scheme, the barrel is changed to be directly above the barrel, and a telescopic stock, an inertial locking mechanism and a closed chamber are adopted. The diameters of the first scheme and the second scheme are both 5.8 mm. The third scheme is to improve the caliber to 9mm on the basis of the second scheme. The main improvement is to change the telescopic butt stock into a downward rotating folding butt stock, and the barrel and the barrel seat are detachable. The fourth scheme is a stereotyped scheme, which adopts telescopic stock, and the barrel and barrel seat are integrated.
