Description

Technical Field

[0001] This utility model relates to the field of missile aiming barrels, specifically to a structure for a vehicle-mounted missile aiming barrel. Background Technology

[0002] The scope barrel of the vehicle-mounted missile sight is the heart and shell of the optical aiming system. It provides a precise and stable mounting reference and support structure for the objective lens, lens group, beam splitter, sensor and other components. The coaxiality and spacing of all optical components are guaranteed by the high-precision machining of the scope barrel, forming a robust sealed or semi-sealed environment to protect the delicate optical components and sensors inside from physical impact, dust, moisture and other external environmental damage.

[0003] As a component directly connected to the lens in an optical aiming system, the scope barrel has extremely small dimensional tolerances, especially those within 0.02 mm and the sectional position tolerances. These tolerances are key factors in determining the ease of debugging the optical aiming system. Therefore, making the structure of the scope barrel simpler and more reasonable, thus easier to manufacture, is an urgent problem to be solved. Accordingly, this utility model proposes a scope barrel structure for a vehicle-mounted missile aiming device. Utility Model Content

[0019] To better illustrate the content of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments:

[0020] have Figures 1-2 As shown, this utility model discloses a vehicle-mounted missile sight barrel structure, including an annular head end 1, a hollow annular middle section 2 with a frustum-shaped upper end, and an annular connecting end 6. The middle section 2 is fixedly connected to the head end 1 by a bracket 5 of three annular arrays. The head end 1 is provided with a first annular groove 9 and a second annular groove 8. The middle section 2 is provided with a columnar inner cavity 15. The upper end of the columnar inner cavity 15 is provided with a central hole 10. The upper side of the columnar inner cavity 15 is also provided with a third annular groove 12 located below the central hole 10. The connecting end 6 is provided with a fourth annular groove 13.

[0021] Furthermore, a first protruding ring 3 is provided on the outside of the connecting end 6, and a second protruding ring 4 is provided on the lower side of the first protruding ring 3 on the connecting end 6.

[0022] Furthermore, the inner wall of the columnar inner cavity 15 is also perforated by two through holes 14.

[0023] Furthermore, a first step portion 11 is also provided on the upper side of the third annular groove 12.
