Description

Technical Field

[0001] The utility model relates to an infrared sight, belonging to the technical field of infrared sights. Background Art

[0002] Infrared sights, also known as infrared sights, are instruments that use near-infrared light sources to illuminate targets, and targets reflect infrared light, which is converted into photoelectric images for nighttime aiming. They are composed of infrared searchlights, photoelectric transformers, sights, and power supplies. By installing a ferrule at the bottom of the infrared sight, the ferrule is snapped onto the card bar seat on the infrared sight device, wherein a threaded hole is provided on one side of the ferrule, and a positioning screw for limiting the relative position of the card bar and the card bar seat is threadedly connected in the threaded hole. Since the threaded connection between the positioning screw and the threaded hole is in an exposed state, small debris can easily enter the threaded connection between the positioning screw and the threaded hole. Since the threaded hole is closed, it is more troublesome to remove small debris in the threaded hole. Therefore, it is necessary to design an infrared sight that is easy to clean small debris in the threaded connection. Utility Model Content

[0012] 2. Insert the clamping strip seat into the clamping sleeve, and then turn the positioning screws between the upper internal thread sleeve and the lower internal thread sleeve to achieve the purpose of limiting the relative position of the clamping sleeve and the clamping strip seat by using the positioning screws. When small debris enters the space formed by the upper internal thread sleeve and the lower internal thread sleeve and affects the turning of the positioning screws, the lower internal thread sleeve can be separated after removing the connecting screws, so as to conveniently clean the small debris that enters the threaded connection part.
