Description

Technical Field

[0001] This utility model relates to the field of aiming scope technology, specifically to a clear and stable low-light aiming scope. Background Technology

[0002] Low-light sights are used to improve shooting accuracy in low-light environments. The weak light reflected from the target is converged by the objective lens and imaged on the cathode surface of the image intensifier. The light is converted into electrons through photoelectric conversion. These electrons are amplified step by step by the image intensifier, and the infrared light is converted into visible light. Finally, an image with sufficient brightness and clarity is formed on the fluorescent screen for the user to observe and aim. Low-light sights are usually used at night. However, during nighttime use, the surface of the objective lens may form water droplets due to temperature differences, which can lead to unclear imaging. Utility Model Content

[0003] The technical problem to be solved by this invention is to provide a clear and stable low-light aiming scope that addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A clear and stable low-light aiming scope includes a scope barrel, an objective lens mounted at the front end of the scope barrel, a connecting seat in the middle of the scope barrel, an image intensifier and a reticle mounted inside the connecting seat, an eyepiece assembly mounted at the rear end of the scope barrel, a ring-shaped outer shell surrounding the front end of the scope barrel, a ring-shaped heating wire connected inside the outer shell, an extension shell below the front end of the scope barrel, a conductive wire connected inside the extension shell, a power supply mounted on the connecting seat, one end of the conductive wire connected to the ring-shaped heating wire, and the other end connected to the power supply inside the connecting seat, and heat dissipation holes evenly distributed on both sides of the front end of the scope barrel corresponding to the position of the ring-shaped heating wire.

[0005] Furthermore, the outer shell and the extended shell are welded to the outer wall of the lens barrel.

[0006] Furthermore, a connecting sleeve is installed at the front end of the lens barrel, the outer ring of the connecting sleeve is connected to the inner wall of the lens barrel by threads, a convex ring is machined at the tail end of the connecting sleeve, and a groove is opened on the front side wall of the lens barrel, with the convex ring disposed in the groove.

[0007] Compared with the prior art, the present invention provides a clear and stable low-light aiming scope. The heat generated by the heating wire is blown from the heat dissipation hole to the surface of the objective lens, so that the surface can be kept dry. The heat dissipation hole is located on the side of the scope barrel to prevent water droplets from entering the heat dissipation hole. At the same time, a connecting sleeve is installed at the front end of the scope barrel. When the aiming scope is not in use, the connecting sleeve can block the heat dissipation hole to prevent dust and other objects from entering the heat dissipation hole. Attached Figure Description

[0009] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0010] like Figure 1 and Figure 2 As shown, a clear and stable low-light aiming scope includes a scope barrel 1, an objective lens 2 mounted at the front end of the scope barrel 1, a connecting seat 3 in the middle of the scope barrel 1, an image intensifier and a reticle mounted inside the connecting seat 3, an eyepiece group 4 mounted at the rear end of the scope barrel 1, an outer shell 5 on the outer side of the front end of the scope barrel 1, and an extension shell 6 below the front end of the scope barrel 1. The outer shell 5 and the extension shell 6 are welded to the outer wall of the scope barrel 1. An annular heating wire 7 is connected inside the outer shell 5, and a conductive wire 8 is connected inside the extension shell 6. A power supply is installed in the connecting seat 3. One end of the conductive wire 8 is connected to the annular heating wire 7, and the other end is connected to the power supply inside the connecting seat 3. When the aiming scope is used at night, the power supply is turned on to control the temperature of the heating wire. Heat dissipation holes 9 are evenly distributed on both sides of the front end of the scope barrel 1 corresponding to the position of the annular heating wire 7. The heat generated by the annular heating wire 7 blows hot air through the heat dissipation holes 9 to dry the water droplets and fog on the surface of the objective lens 2, so that the surface of the objective lens 2 dries as quickly as possible.

[0011] In this embodiment, the heat dissipation holes 9 are located on both sides of the front end of the lens barrel 1 to prevent water droplets from accumulating and flowing into the heat dissipation holes.

[0012] A connecting sleeve 10 is installed at the front end of the scope barrel 1. The outer ring of the connecting sleeve 10 is connected to the inner wall of the scope barrel 1 by threads. When the scope is in use, the connecting sleeve 10 is screwed outward to expose the heat dissipation hole. A convex ring 11 is machined at the tail end of the connecting sleeve 10. A groove 12 is opened on the front side wall of the scope barrel 1. The convex ring 11 is placed in the groove 12 to prevent the connecting sleeve 10 from being screwed out too much and detaching from the scope barrel 1. After the scope is used, the connecting sleeve 10 is screwed inward to block the heat dissipation hole and prevent dust from entering the heat dissipation hole.

[0013] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
