The light adjustment part 11 corresponds to the light transmission part 10 to adapt to the light intensity in different environments.

[0027] The scope tube 1 is connected to the base 8 via the positioning protrusion 9, making the installation position more accurate; the light transmission part 10 and the light adjustment part 11 work together to adjust the brightness of the reticle; the fast focus adjustment ring 32 drives the eyepiece lens group 31 to achieve magnification switching; the protective cover 12 covers the objective lens end 2 and the eyepiece end 3 to prevent external damage; the overall structure ensures the stable use of the scope through sealing treatment and modular design.

[0028] The mounting base 8 includes a guide rail mounting seat 81, with arc-shaped bases 82 at both ends of the guide rail mounting seat 81. A first rotating seat 83 is provided on the side of the arc-shaped base 82, and an arc-shaped upper plate 84 is rotatably connected to the first rotating seat 83. The arc-shaped upper plate 84 is in contact with the outer wall of the scope tube 1. A fixing hole 85 is provided on the arc-shaped upper plate 84, and a connector 86 is provided in the fixing hole 85 for fixing the arc-shaped base 82 and the arc-shaped upper plate 84.

[0029] The guide rail mounting base 81 of the mounting base 8 and the arc-shaped base 82 are connected to the arc-shaped upper plate 84 through the first rotating seat 83. Combined with the fixing hole 85 and the connector 86, the scope tube 1 and the base 8 can be quickly disassembled and assembled.

[0030] The guide rail mounting base 81 is provided with a positioning groove 87, and the lower part of the scope tube 1 is provided with a positioning protrusion 9. The positioning protrusion 9 corresponds to the positioning groove 87 and is used for positioning when the scope tube 1 and the mounting base 8 are connected.

The brightness of the lighting element 116 can be controlled by adjusting the knob 117. The reticle can be clearly displayed under strong light or dim light conditions, avoiding aiming deviation caused by glare or insufficient brightness. The battery compartment 114 is independently set on the side of the dimming part 11. It can be equipped with button batteries or rechargeable lithium batteries, etc., and adopts a separate design from the lighting element 116, which facilitates battery replacement without affecting the optical path calibration.

[0036] The scope tube 1 is provided with protective covers 12 at both ends. The protective covers 12 include objective lens protective cover 121 and eyepiece protective cover 122, which correspond to the objective lens end 2 and the eyepiece end 3, respectively.

[0037] The objective lens cover 121 and the eyepiece cover 122 cover the objective lens end 2 and the eyepiece end 3 respectively. They can be made of impact-resistant polycarbonate material and silicone sealing rings to prevent the lens from being scratched or bumped during transportation or field use.

[0038] The working principle of the scope zoom device provided by this utility model is as follows:

[0039] The scope tube 1 is connected to the base 8 via the positioning protrusion 9, making the installation position more accurate; the light transmission part 10 and the light adjustment part 11 work together to adjust the brightness of the reticle; the fast focus adjustment ring 32 drives the eyepiece lens group 31 to achieve magnification switching; and the protective cover 12 is made of impact-resistant material to protect the lens.
