Self-adaptive gas regulator for semi-automatic shotgun

Abstract

The invention discloses a self-adaptive gas regulator for a semi-automatic shotgun. The self-adaptive gas regulator comprises a regulator body, a sealing gasket, a sealing spring, a spring seat and apositioning block; the large end face of the front end of the regulator body is provided with a bump to form a closed air surface; a plurality of vent holes are uniformly distributed along the axial direction on the closed air surface; the vent holes communicate with a cavity of the regulator body; the regulator body and the spring seat are in threaded fastened connection with each other and are connected with the positioning block through connecting screws; the positioning block is connected to the spring seat; the sealing gasket is arranged on the regulator body in a sleeving manner; as thesealing spring is tightly attached to the closed air surface of the regulator body, the sealing spring is sleeved between the sealing gasket and the spring seat; when the regulator is installed in cooperation with a gun body, positioning is realized by virtue of the spring seat and the positioning block. According to the self-adaptive gas regulator disclosed by the invention, the semi-automatic shotgun is additionally provided with a spring regulation structure, so that the automatic regulation of the energy of an air guide system can be realized without switching the regulator when the shotgun is firing bullets at different chamber pressure.

Description

technical field [0001] The invention belongs to the technical field of firearms and relates to an adaptive gas regulator for a semi-automatic shotgun. Background technique [0002] 12 gauge semi-automatic shotgun uses 2 3 / 4 Inch and 3-inch shotgun ammunition, because there are many types of ammunition in the market, the energy difference is very large. The traditional gas regulator needs to set multiple gears for energy adjustment, and the structural space of firearms is limited. Generally, only 3 gears can be set. to 4 gears, such as "0", "1", "2" and "3" (such as figure 1 shown), where "0" is the manual operation gear (generally people don't like to use it), and the remaining 2 to 3 gears correspond to semi-automatic firing. There are too many bullets without corresponding gears, resulting in many shooting failures or large recoil when firing these bullets, making the shooting experience uncomfortable.

[0002] 12 gauge semi-automatic shotgun uses 2 3 / 4 Inch and 3-inch shotgun ammunition, because there are many types of ammunition in the market, the energy difference is very large. The traditional gas regulator needs to set multiple gears for energy adjustment, and the structural space of firearms is limited. Generally, only 3 gears can be set. to 4 gears, such as "0", "1", "2" and "3" (such as figure 1 shown), where "0" is the manual operation gear (generally people don't like to use it), and the remaining 2 to 3 gears correspond to semi-automatic firing. There are too many bullets without corresponding gears, resulting in many shooting failures or large recoil when firing these bullets, making the shooting experience uncomfortable

[0003] Italian-made Benelli shotguns have regulators with similar principles, but they cannot be disassembled, which limits the interchangeability of the two regulators and reduces the fun of the shooting experience.
