Description

Technical Field

[0001] The invention relates to the technical field of aiming baseline zero position detection, and in particular to a portable detection device for aiming baseline zero position of an infrared sight. Background Art

[0002] The infrared sight is composed of an infrared image converter tube, a reticle, etc. It is used on firearms and can aim at targets at night. Infrared sights are also used in medical treatment, firefighting, and industry, such as observing inflammatory lesions in the human body, observing the hidden situation of a fire, or the erosion of the blast furnace wall. The infrared sight needs to be calibrated before leaving the factory. During use, due to the aging of the infrared image converter tube and vibration, the aiming baseline zero position will move, reducing the aiming accuracy, and frequent calibration is required. In addition, after long-term use of the infrared sight, if the zero position movement detected during calibration exceeds a certain limit, it can be used to judge whether the infrared sight is scrapped.

[0003] At present, the traditional detection method of the zero position movement of a gun sight is to observe the scale and read the readings with the human eye, that is, the inspector observes a special scaled target through the gun sight and reads the readings before and after the shooting test. The difference between the two readings is the zero position movement of the sight. The efficiency of detecting the zero position movement of a gun sight by the logarithmic method of the human eye is low and is prone to large errors. In view of this, we propose a portable detection device for the zero position of an infrared sight aiming baseline. Summary of the invention

[0012] Preferably, the chassis assembly includes a steel section, and grooves are formed on both sides of the upper end surface of the steel section, and a special-shaped protrusion is formed in the middle of the upper end surface of the steel section by means of the groove, and angular protrusions are formed on the edges of both sides of the upper end surface of the steel section by means of the groove.

[0013] Preferably, the upper end surface of the mounting seat is provided with a groove body that is adapted to slide against the outer edge surface of the movable seat, and an arc-shaped positioning strip is formed in the center of the inner wall of the groove body. The outer edge surface of the movable seat is provided with an arc-shaped positioning groove that is slidably adapted to the arc-shaped positioning strip in the center, and the lower end surface of the mounting seat is provided with a limiting groove 1 in the center that is adapted to be engaged with the special-shaped protrusion, and limiting grooves 2 that are adapted to be engaged with the angular protrusion are provided on both sides of the lower end surface of the mounting seat, and angle markings are provided on one side of the movable seat and the mounting seat.
