technical field

The utility model relates to a scope for a gun, more specifically, it relates to a replaceable and fast gun calibration device.

Background technique

On guns equipped with scopes, a gun calibration device is generally installed on the scopes to adjust the trajectory to ensure shooting accuracy. Nitrogen gas is filled in the internal structure gap of the gun calibration device and the assembly structure gap between the gun calibration device and the scope, so as to provide necessary anti-mildew protection for precision parts. In different environments, due to the different shooting factors such as light and wind speed, the adjustment accuracy of the gun sights used is often different. The ideal way to use the gun calibration device is to select a gun calibration device with appropriate calibration accuracy according to the environment. , but in order to ensure the sealing of nitrogen gas in the existing gun calibration device, the gun calibration device is usually permanently fixed on the scope, and will not be removed after installation, so it is impossible to replace the calibration with different calibration accuracy on the same gun. gun device. The utility model patent with the publication number CN201706979U disclosed on January 12, 2011 a W/E adjustment screw mechanism with a locking structure for a scope, including an adjustment bolt, a dial, a knob seat, an index ring, a dial and an adjustment screw mechanism. The bolts are fixed together by at least three fixing screws. A positioning screw is embedded axially inside the adjusting bolt. The upper end of the positioning screw is equipped with an adjusting hand wheel, and its lower end is a cam or eccentric wheel structure. The lower end of the positioning screw A locking pin radially penetrating through the adjusting bolt is connected to the top of the side. The head of the locking pin is covered with a first spring, and a straight groove matching the top end of the locking pin head is opened on the inner wall of the knob seat. Compared with the prior art, the utility model has the following advantages: improved product stability and precision, easy to use, various functions, waterproof function, W/E adjustment screw with uniform and light hand feel, easy to switch between locking and loosening states , Reliable, clear positioning, and also has a zero return function. But this utility model can not solve the replacement problem of the school gun device of same gun.
