The present invention relates to the technical field of telescopic sight accessories, in particular to a fast flipping bracket for a telescopic sight. The fast flipping bracket for the telescopic sight mainly comprises a bracket, the bracket being composed of a body (1) and a press plate (2), and the press plate (2) being fixed to the right side of the body (1) via a press plate screw (3), and further comprises a flipping support (4), wherein a connecting block (401) perpendicular to the flipping support (4) is arranged at the bottom of the right side of the flipping support (4); a groove is provided in the left side of the body (1); and the connecting block (401) is embedded in the groove, and the connecting block (401) is connected to the body (1) by means of a positioning mechanism. Compared with the prior art, the fast flipping bracket for the telescopic sight is designed in such a manner that the bracket body is fixed to a gun, the telescopic sight is locked onto the turning support (4), and the bracket is connected to the flipping support (4) by means of the positioning mechanism, so that the flipping support (4) can be rotated on the bracket, thus realizing fast flipping of the telescopic sight on the gun and achieving the purpose of intermittently using the telescopic sight. Double-lock positioning is precise and firm, same is easily started with a button, and devices such as a night vision device can also be fixed to the flipping support (4), thereby achieving fast flipping and intermittent use of different gun accessories, and the range of application thereof is wide.

An impregnating detection system and method. The system comprises a liquid impregnating device (100) used for placing a workpiece to be detected and performing underwater high-pressure airtightness detection. The liquid impregnating device (100) is connected to a pressurization device (200) for increasing water pressure and a correction device (300) for detecting and correcting the experiment accuracy. After the experiment accuracy is corrected via the correction device (300), the interior of the liquid impregnating device (100) is pressurized via the pressurization device (200), so as to enable a water pressure in the liquid impregnating device (100) to reach a pre-set experiment demand value. By means of using the impregnating detection system and method, various deep water simulative airtightness detection experiments can be conveniently performed, the operation is easy and convenient, and the experiment efficiency is improved.
