The upper end of the lower protective cover 35 is fixedly connected with evenly distributed spring plates 37 (each spring plate 37 has a protrusion fixedly connected to the upper end of its outer arc surface). The upper ends of the spring plates 37 are engaged with the inside of the annular rib groove 33. A rubber sealing gasket 13 is provided in the middle of the outer arc surface of the lens barrel 1. A rubber sealing gasket 2 14 is provided at the lower end of the inner wall of the upper protective cover 31. The rubber sealing gasket 1 13 and the rubber sealing gasket 2 14 are installed together. The protective mechanism 3 also includes an annular rib groove 2 34, a connecting cylinder 36, an annular rib 38, and a hexagonal rib block 39. The annular rib groove 2 34 is provided at the lower end of the upper protective cover 31. The annular rib 38 is fixedly connected to the upper end of the lower protective cover 35. The annular rib 38 is inserted into the annular rib groove 2 34. The connecting cylinder 36 is fixedly connected inside the lower protective cover 35. The outer surface of the connecting cylinder 36 is provided with external threads. The lower end of the inner wall of the lens barrel 1 is provided with internal threads 6. The internal threads 6 are threadedly connected to the external threads on the outer surface of the connecting cylinder 36. The lower end of the outer arc surface of the lower protective cover 35 is fixedly connected with a hexagonal rib block 39. The protective mechanism 3 also includes an annular groove 34. 2. An annular groove 32 is located inside the upper protective cover 31. A corrugated protective plate 4 is fixedly connected to the upper end of the lens barrel 1. The outer surface of the corrugated protective plate 4 is inserted into the interior of the annular groove 32.

The upper protective cover 31 is fitted onto the outer surface of the lens barrel 1 from top to bottom. The corrugated protective plate 4 is inserted into the interior of the annular groove 32. At the same time, the second rubber sealing gasket 14 passes through the first rubber sealing gasket 13, and the upper end of the second rubber sealing gasket 14 and the lower end of the first rubber sealing gasket 13 are in contact, improving the sealing performance at the connection between the upper protective cover 31 and the lens barrel 1.

After application, accumulated dust can be easily washed away by rainwater, reducing significant manual maintenance costs and maintaining cleanliness for a long time. It is transparent and does not affect the light transmittance of the glass. It is super-hydrophilic with a water contact angle of less than 5 degrees and also has anti-static properties. The corrosion-resistant layer 9 of lens 2 can be a fluoride coating. By coating a layer of fluoride with a thickness of one-quarter wavelength on the surface of lens 2, the reflection of specific wavelengths of light by lens 2 can be minimized. Multi-layer coating can work on a variety of colors of light, greatly improving the light transmittance of lens 2 and reducing diffuse reflection between lenses, thereby improving image contrast and sharpness. At the same time, the fluoride coating has an anti-oil function, preventing oil stains from adhering and ensuring image quality without affecting the lens transparency. Lens layer 10 can be made of optical glass, and high-strength layer 11 can be made of optical-grade polycarbonate. Optical-grade polycarbonate has good light transmittance, allowing light to pass through the material with high transmittance, while also providing a certain degree of strength support, making it suitable as a high-strength support layer for lens 2.

[0026] The working principle of the high wear-resistant transparent lens cover provided by this utility model is as follows: When the lens barrel 1 is not in use, the operator places the upper protective cover 31 onto the outer surface of the lens barrel 1 from top to bottom. The corrugated protective plate 4 is inserted into the annular groove 32. Simultaneously, the second rubber sealing gasket 14 passes through the first rubber sealing gasket 13, and the upper end of the second rubber sealing gasket 14 and the lower end of the first rubber sealing gasket 13 are in contact, improving the sealing performance at the connection between the upper protective cover 31 and the lens barrel 1. Then, the lower protective cover 35 is placed onto the outer surface of the lens barrel 1 from bottom to top. Simultaneously, the operator rotates the lower protective cover 35 through the hexagonal rib 39. The external thread of the connecting cylinder 36 inside the lower protective cover 35 connects with the internal thread 6 at the lower end of the inner wall of the lens barrel 1, achieving a stable connection between the lower protective cover 35 and the lens barrel 1. During the upward connection of the upper protective cover 35, the spring sheets 37 are all compressed by the inner wall of the upper protective cover 31, causing the spring sheets 37 to undergo elastic deformation towards the center of the lens barrel 1. When the annular rib 38 is inserted into the annular rib groove 34, the protrusions on the upper end of the outer arc surface of the spring sheet 37 are engaged with the inside of the annular rib groove 33, realizing a quick and stable connection between the upper protective cover 31 and the lower protective cover 35, achieving comprehensive protection for the lens barrel 1. Furthermore, under the threaded connection between the connecting cylinder 36 and the lens barrel 1, a stable connection is achieved between the upper protective cover 31 and the lower protective cover 35 and the lens barrel 1, preventing external dust from entering the interior between the upper protective cover 31 and the lower protective cover 35, thereby preventing dust from causing wear on the lens 2.
